Espartan Jagami

Name: Espartan Jagami

Real age: 18 years old

Apparent and physical age: 10 years old

Personality: Espartan is a kind, loving, affectionate, altruistic, understanding, innocent, and pure child. Spartan calls all the girls he loves "onee-san" at the end, for example Sirin Onee-san, Mei Onee-san, Kiana Onee-san, Bronya Onee-san. he is the personification of purity both literally and symbolically. Espartan is characterized by a habitual warmth in his way of being, being quite tender all the time, and he also acts that way by his own will and nature even if he has seen and felt horrible things. He is a child who only wishes to love and live in peace with his family like ordinary, common people. He loves life, loves his life, and loves his family, but basically he loves almost everything. He always tries to use his words as his first method of defense or attack. He doesn't like to fight, but if it's to defend himself or his Onee-sans, he will do it without a second thought. Even if Espartan is subjected to a lot of physical, verbal, or psychological harm at times, there is always a way to put his ideals, feelings, and strength first so that it doesn't affect him in the future no matter how much pain he has felt before or now. Despite having lived through a great and enormous trauma as a child, he did not forget it but accepted it and also carries it in his heart, since that is where he met his beloved Sirin Onee-san and later Mei Onee-san. He sees the positive in it within all the bad things he lived through, in addition to realizing thanks to his Onee-sans that his life is not only important but that his only meaning in life is to be able to live it with the greatest possible love. Espartan believes in the hope of a better world, he sees the beauty of the world just like Kiana Onee-san, but he also does it in his own way through love. For Espartan, the most important thing is love, not only from his family but from the whole world; we all have love and it can be used in good or bad ways, as Otto or Kevin did. His strength is his love, and love is found in all existence. He is a being who should not or did not deserve love since he came from absolutely nothing and was destined to destroy everything and everyone, yet they loved him even after he had been treated as an object or toy by humanity itself—a ray of hope. Mei was the one who gave him everything he needed. Thanks to Mei and Sirin, he was able to see the beauty of this world and also the horrible side of it, not because of them but because of what he has lived through both in Babylon and currently. He knows this and is willing to watch over the love of others as well as his own. Espartan is also quite intelligent and does not like being underestimated or seen only as a small, adorable child—although, ironically, he loves that, just not all the time. Since sometimes Mei, Kiana, and Bronya don't want him to go with them on missions or to know certain things because they believe they will be too complicated or dangerous for him, and he wishes more than anything to be there for them and protect them, even though he shows all his Onee-sans that he is not always just a small, adorable child. Moreover, on occasion Espartan makes them reconsider things, like Mei when she was in World Serpent, demonstrating that despite his appearance he is very intelligent and wise.

Appearance: Espartan does not have the ability to grow and is also eternally long-lived due to his Herrscher gem; meanwhile, he remains young and small forever due to his natural purity. He has the appearance of a small, adorable, and kind child, and he is... but for him it is not really a curse if he can continue helping the world. He also has large red eyes due to the being or demon that lives inside him, but they are kind, tender eyes full of love and innocence, along with short red hair somewhat long at the tips that falls slightly horizontally in three strands toward his forehead. He is slim and measures approximately 1.50 meters in height, being a little shorter than Sirin. He generally wears casual clothes, solid-colored t-shirts or sometimes with a cute animal or video game character that he likes, or also t-shirts with HOMU (a Honkai Impact mascot) on them, and shorts.

Base powers and those of the Demon inside him (base): Espartan as such does not have powers originating from the demon inside him. He has passive cell regeneration at basically 100%, meaning he could never be eliminated even if his entire body is destroyed; the only way is by wearing him down. Obviously, the more powerful the attack, the faster he will die. Using the previous example, if he does not die from a single very, very powerful attack, he will die from 2 attacks—but this only depends on the opponent.

The demon itself, being a being born from the absolute void, has quite a few powers. It is an enormous, totally red and long monster with huge teeth and claws combined with its skin. It has empty eye sockets and enormous ones that contain a small red pupil. It can absorb all organic life (especially blood) and use it to become stronger. It is voracious, aggressive, and erratic. It launches very hot blood rays from its enormous mouth and from its claws, also some blood slashes; this also happens with its enormous mouth and long tail.

Herrscher of Rock: The Herrscher of Rock has a brilliant golden-yellow aura, and his hair also turns golden as do his eyes. He acquires beautiful, gorgeous long white clothing like a light trench coat of his size that gives him a more friendly and adorable appearance, being literally a god in the body of a tender child, plus warm transparent golden fabrics around his back and limbs, and golden boots. His pupils become orange-golden rhombuses.

Powers of Herrscher of Rock: Espartan can use any rock on the planet to attack or protect himself, especially to protect. He can grant Brilliant Rock shields, which are a very resistant transparent shield that he uses for himself or his Onee-sans in battle. He can also launch enormous rocks propelled by very powerful golden Honkai energy, as well as sharp triangles that he uses as quick ranged attacks. He can also summon rocks to shape them into giant hands or arms to attack. He can also summon his own rocks, which are the most powerful. He can teleport at will, fly, and throw beams of golden Honkai energy, and finally also create a slight imperfect dominion of great and enormous mountains of rocks (like the Chinese mountains) to trap his enemies, but since it is an imperfect dominion he can only do it on land; he does not have a plane where he can do it without destroying things. In addition, Espartan fights quite a bit hand-to-hand because he is small and agile; his body is very resistant and hard, which is why he likes to hit and fight physically. (It should be noted that he learns these abilities over time, and Espartan does not do it immediately or know how to use them at the beginning.)

Herrscher of Planet: Espartan acquired a very powerful and showy technological Honkai armor, white and golden-yellow like his Honkai energy. It makes him look a little more threatening than the Herrscher of Rock, and it is somewhat inspired by a game, like armor, since Espartan likes them a lot.

Powers of Herrscher of Planet: They are basically the same powers as the Herrscher of Rock, only stronger, and he can also separate his armor to make it fire beams of Honkai light. Finally, his plane is mastered, and he can also summon an enormous yellow Honkai planet Earth—not of real size, but it is his most powerful and destructive ability. He can also literally create mountains to increase his power and also protect others from very resistant auras, giving them advantages in battle.

Herrscher of Pure Love: Espartan leaves behind his armor to return to that tender and warm trench coat, but longer and more showy. It is similar but not in details. There are many hearts in his appearance; it has golden colors combined with pink, his hair becomes much more pink and so do his eyes, and he also gets several shiny fabrics around him in the shape of a heart, and his pupils also become hearts. He also obtains a light, beautiful cape that has silhouettes of his Onee-sans printed on it. In fact, all his clothing has nods to his Onee-sans, such as a pair of scissors on his chest that belong to Sirin, a white and shining flower that is Kiana located on his left arm, a katana that is Mei located on his right arm, and Bronya located on his neck with a motorcycle of hers.

Powers of Herrscher of Pure Love: Here Espartan can continue summoning rocks of a shiny pink tone, and he launches even more powerful beams, but he also generates things with pure pink and shiny Honkai energy, such as hands, then weapons, beasts, etc. It is also more focused on support, since his Herrscher stands behind his Onee-sans' backs to give them very strong and forceful benefits and advantages, as well as protection and support with things they might not be so attentive to.

Weaknesses: Espartan is practically an innocent child, full of love and compassion for everything and the whole world, but he is not perfect. In fact, he is somewhat naive, if not quite so. He knows the evil there is in the world and understands it, but he still does not carry it in his heart. Precisely, his forgiveness of Sirin is something very questionable, since he basically forgave a genocidal person; he sincerely admits it and does not care, and he knows it. His love is mostly focused on what he lived with her and how well he really knows her, being really the only one who could save Sirin. Also, although it is not shown in the summary of his story, there are times when Espartan caused difficulties for his own Onee-sans by being kidnapped, hurt, or letting himself be carried away by his innocence, sometimes putting others and himself in danger. Also, Espartan is someone who has difficulty finding evil in people, even in those he hates, because for him there is always a good or understandable reason, and that is usually how it is, but this can cause him to sometimes be manipulated by some villains, which fortunately improves over time. Finally, Espartan also has something a little distant from the rest, but he does not like them to worry about him. He accepts love, pity, and care without hesitation, but he does not like his Onee-sans to worry so much because he feels he is causing them unnecessary pain by thinking so much about his well-being, but he cannot deny how good it feels to be comforted, cared for, and loved. This occurs in a large part of the story since the demon he has inside him causes him nightmares and horrible visions of himself and his Onee-sans in order to weaken his mind and be able to escape his captivity and destroy everything. This caused Espartan sometimes to talk about sacrificing himself multiple times to save his Onee-sans; they obviously reproached him for that and asked him please not to think about such painful things, but he felt that he really owed them, not only Mei but all of them, for giving him so much love and affection without expecting anything in return. He did not want to die at all; he wanted to live, but the fact that he feels that the only way to do something for them or save them from a complicated situation is by sacrificing himself is something he still thinks about even today. But Espartan is strong in his convictions and psyche by not letting himself fall into sadness, depression, or trauma even when the demon reminded him of his harsh and horrible tortures in Babylon. But he never really tells his Onee-sans as such so as not to worry them, but this meant that in the end, ironically, they all worried when Espartan could not resist suffering so many discomforts and disturbances that his mind faltered when he could no longer resist, and this caused thousands of innocents to die. Espartan was distant for a few weeks because of this, since he had never killed an innocent person—and in fact he did not; he simply did not know how to deal with it alone. Fortunately, he was not alone; he never was, and now, after helping his Onee-sans so many times, all that attention was returned to him alone. This not only strengthened his relationship with his Onee-sans but also made them more united as friends and as a family.

Origin and history:

The Arrival

Espartan's origin is somewhat complex to explain. He was not born from anyone, from nothing, or anything like that. He is not the remnant of a god or anything of the sort. Espartan was born in the void of space, of the universe and galaxies. In an absolute blackness, all the evils of existence itself gathered there: all the embodied violence of living beings, the abysmal destruction of planets and galaxies, the most negative feelings of all beings—envy, hatred, jealousy, deceit, greed, war, destruction, death, and chaos. Basically everything negative that could ever exist, and from there, from such pure negativity, from horrible pure feelings, from pure pain, from pure chaos, something too pure was born. That was Espartan Jagami. From all that evil he was born, without a mother, without a father—a too-pure child but with a very, very bad and evil being inside him. Although he did not know it yet, he simply knew. A portal opened in Siberia in 1999; Espartan fell several hundred meters to the snowy ground, breaking his bones, destroying his flesh, face, and small body. He had the appearance of a small 10-year-old boy. Sometimes, from all the pain he felt, tears came from his eyes at such torment, but for him... it felt beautiful because it was the first thing he felt in his new life. It was uncomfortable, yes, but he was happy. Then, after his body regenerated due to the being inside him, he decided to keep moving through Siberia for several thousand meters without even checking if he was lost, since he did not even know what that was. He was practically a newborn child. His legs hurt, swelled, and bled; he did not care, since it was the first thing he felt in his life, but more importantly, he marveled at the dark sky full of stars, and the further he went, the more aurora borealis there were. It was so beautiful that it did not matter, this pain that little by little was becoming uncomfortable; even so, he endured it. As Espartan walked in a straight line, he encountered polar bears that tore him apart multiple times while eating him until he managed to escape with a very bad sensation of pain this time, since they did not give his body a break for a good while. After that, he passed through frozen rivers that froze his limbs and broke his legs. He also encountered wolves, and they also tore him apart and ate him. He approached them out of innocence, and they seemed beautiful creatures to him; even though they had hurt him a lot, he did not hate them. Espartan continued, and continued suffering blindly with hunger, eating rocks or snow since he did not know what was food and what was not, so he put anything in his mouth to see if it calmed his hunger. Flavors were nonexistent and new to him; he tried to find the taste in them. But after walking too many kilometers, he came across a town. Upon approaching that different place with small wooden boxes, he went and inside the houses saw people, families... They were happy with the fireplace on, hot chocolate, and large humans... hugging them and kissing their cheeks. He went to other cabins to spy, and it was the same scene, but he did not fully understand it. But after what little he had lived, seeing that so warm, so calm... He wondered what it was, and then, after talking with people from the place, he realized that they were "family," but he had no family since he did not come from anyone; he was alone. Espartan wanted a family! But no one wanted to be one, nor were there children, since Espartan was naked because that was how he came into the world. Later he learned about clothes, but he had no money and did not want to steal either, so he used balls of garbage or cardboard. His stay in the town was very warm even though he was a homeless person; he learned to speak quickly due to the powerful being inside him, but he was still very innocent. But one day something exploded... killing several adults. Espartan did not understand death either, and that was his first glimpse of it. A short time later, some scientists arrived at the place and took him away. All the children were scared and did not trust these men, since they had just lost their parents, but Espartan was the only one happy and optimistic, but also naive. Espartan was taken to the Babylon Tower, where he was quickly tortured and used as a test subject. Espartan, being very optimistic, believed it was something good, and the scientists liked to mock him by telling him that this suffering was to make medicines for people like those who died in the town, so he took that pain as something "good" or for a good cause. But he felt every horrible thing they did to him, but he had something somewhat special... Since Espartan did not even have any resistance to Honkai, he could not have the tortures of the children for the stigmas, so Espartan was subjected to tortures on the physical body itself. Espartan suffered all kinds of horrifying tortures, and his body always regenerated.

Sirin arc: In the meantime, one day he was taken to another room since they had already gotten more children. It was a shared room, and Sirin was there. Before becoming the Herrscher, she was just a girl also tortured and traumatized like him, but she had lost her mother and her friends, and she felt a deep hatred for the scientists. Espartan, on the other hand, did not, since he said it was for a good cause, and Sirin explained things to him, as if she were a... an older sister. Espartan and Sirin became very good friends. Despite everything... Sirin became very pessimistic, depressed, and angry at times when thinking about what she had lost, but Espartan was that point of inflection between the horror, pain, suffering, and death of the place and the tenderness, innocence, kindness, love, and tenderness that Sirin needed. They both needed a family; Sirin lost hers, and Espartan never had one. So, innocently, he told her that if he could call her... "Onee-san, Sirin Onee-san." Sirin, in tears, nodded and accepted; she accepted him as her little brother and tried to protect him, although she also needed protection. They both tried to survive and endure the pain. Espartan had heard about the Valkyries and trusted that they would come to save them, but it never happened... And Sirin, not so optimistic, knew she could not trust them, only wish and beg for this hell to end. But as time went on, Espartan grew weaker. It turned out that his body did not have infinite regeneration, and his body was wearing out, and the scientists did not care. Each time Espartan returned to Sirin weaker and skin and bones. Sirin did not know what to do; her little brother was slowly dying in front of her, and she could do nothing. She was helpless and did not know what to do; she was alone. And she was going to be alone forever. Espartan did consider Sirin his sister despite not being blood-related, but that would not be enough. Espartan began to decline; his tender and optimistic attitude ceased, and Sirin tried to cheer him up as he had done with her, but it did not work. Espartan could barely move. Finally, Espartan, in Sirin's arms, confessed the worst... "I want to die..." he said, and Sirin's heart broke. Not even their love for each other made him want to stay with her; he just wanted it to end already. Espartan only wished that Sirin could get out and that he could finally rest. That day the scientists returned, and Sirin tried everything with her small, weak body to keep them from taking Espartan, but they were stronger, bigger... They subdued her, and moreover, they broke her hand at a moment when Sirin, desperate to catch Espartan, reached out toward the door, and a scientist closed it without mercy against her hand and arm. A few minutes after screaming and hitting the door without caring about her hand, from that anger, from that fury, from that pain for... for Espartan, her Herrscher power awakened, killing most of the scientists. But Sirin's powers were unstable and caused some parts of the place to become rubble; one of those was where Espartan was. The scientists fled to their deaths while Espartan fell behind to survive. But it was useless, and he fell into the Honkai core of the Babylon Tower. There he saw something shining. Espartan was hungry... He had not eaten anything, and he remembered when he ate rocks. It was not the best, but it was something... He managed to drag himself and took that gem... And swallowed it with difficulty and need, breaking his teeth and tearing his throat, but he was so hungry and had such a desire to... not die... Full of pain, he accepted his death; he only wished to rest. Rubble fell on his body. The reason the Herrscher gem was there was because it was truly useless—a Herrscher that could do nothing but protect and summon rocks, which is why it was stored there as a Honkai core, but not something truly dangerous or valuable to Otto. Meanwhile, Sirin tried to find Espartan but had no success; she did not know he was on the ruins of part of the Babylon Tower. So she unleashed all her fury, destroying everything and finally giving birth to the Herrscher of the Void. After this came the Second Honkai Eruption arc, where at the end Sirin died and her Herrscher gem passed to Kiana.

My Mei Onee-san arc: It is 2015, and a small aura of Honkai radiation from a Herrscher was detected in what used to be the Babylon Tower. Theresa, Tesla, Einstein, and other Valkyries, including Mei, knew what had happened there (except Kiana). The Honkai energy was little, but the fact that it was in Babylon suggested something quite dangerous. Mei, with the intention of proving her worth and strength after training all this time, insisted, and after some quick tests, she was enlisted to go to the ruins of Babylon. The idea was to eradicate that energy since it was surely malignant or even a Herrscher about to awaken. Upon arriving, Mei found quite a few Honkai beasts, and their difficulty kept escalating, which gave her a bad feeling about what the thing with the Herrscher gem might be. She went deeper into the ruins, and upon reaching a long dark room in a pile of rocks, she saw a golden light inside, overflowing, and the Honkai levels were absurdly powerful. Mei did not back down and decided to enter even when Himeko told her to get out of there. With courage, she removed the rocks while raising her katana with the intention of killing, and... She saw at the bottom a small boy with short red hair looking at her with fear and tears. He was... okay, that is, his body was not skin and bones like before, but he was totally terrified. He said nothing, only whimpered slightly. Mei took pity; she knew he was a Herrscher, but she could not hurt a child... She took him and convinced him to come with her through warmth. Espartan little by little trusted her, and the first thing he remembered or wanted to remember was Sirin, and he said... "Onee-san?" Why? Because the only person who cared for him and loved him called her "Onee-san," and Mei did not want to hurt him, only give him warmth and affection. Mei did not understand why she called her "Onee-san," but she nodded, accepting her "nickname," and after that she took him to St. Freya, getting him out of that horrible place once and for all.

St. Freya arc: After Espartan was taken to the St. Freya headquarters with Mei, she had quite a few problems... Since basically everyone wanted Espartan to die. Why? Because he had a Herrscher gem, the Herrscher of Rock, and after what happened with Sirin, the fact that someone in Babylon was a Herrscher could end very badly... Himeko took some pity, while Kiana and Bronya also wanted Espartan to live. Meanwhile, Otto simply and yandere-ly continued with his plans without giving him importance. Tesla, Fu Hua, Theresa, Einstein, and more intelligent people wanted to kill Espartan, not violently or painfully, but to end his life. Mei fought with her words and reasoning so they would not hurt the child until they finally gave in with the condition that Mei would be watching over him all the time and that he would also be trained to reduce his Honkai levels, which could be unstable, putting a bomb on him as had happened with Mei. Mei then began to take care of little Espartan, trying to cheer him up and accompany him since he was still traumatized by what he had lived through, although he was still kind, good, and innocent, but in a painful way when he innocently told her things he believed were that way or were "correct" but were painfully horrible for someone so small to tell. That is where Espartan learned from Mei, little by little understanding that the life he deserved or that was normal here was that of the Babylon Tower. The warmth of Mei, Kiana, Bronya, Himeko, and even Theresa, Tesla, Einstein, and the other girls made him see that this world is not only pain. Espartan recovered his radiant tenderness, even more than before. He tried to pass the exams, but he was bad at them, both written and physical, since he did not know how to control his powers, and sometimes he had dreams about that Demon inside him. Moreover, they told him the truth about Sirin once Espartan asked Mei why she came there to Babylon for him. Mei told him about the eruption and also about her death, and also that he should never tell Kiana. Espartan understood. Finally, Mei became the most important person to Espartan, even though Mei wanted and loved Kiana more; he did not care, since he loved Mei like never before, because thanks to her he had a life. She saved him not only from Babylon but from a life full of pain. She was his "Onee-san" without asking for anything in return, and she also cared for him, taught him, and gave him love like no other. Thanks to Mei, Espartan became even more loving and pure than before upon knowing the evils and misfortunes in the world, knowing that not everything is good, but that this... This life with them was those beautiful and perfect things for him.

Herrscher of Void arc: After Kiana released Sirin from her slumber and began to wreak havoc, Espartan from a distance saw "Kiana" transformed in the eyes and knew who she was... It was Sirin. She was not dead, but even so, she was there in Kiana. Espartan flew to the ship where Mei was injured with the intention of helping her, although he flew slowly and could not do much since he was not very good at fighting or using his powers. Upon arriving, he saw Sirin more closely, but she did not see him; instead, she left, and Mei was saved by Himeko. Espartan then quickly returned to St. Freya with the intention of seeing how Mei was and what the hell was happening. After that, and after Himeko tried to save them all from Sirin, she died at her hands, leaving a deep mark on Espartan's heart, since he considered Himeko okaa-san like a mother to him.

Sea of Quanta: Espartan manages to quickly help Bronya go for Kiana, so he accompanies her to the Sea of Quanta to rescue Seele, and he succeeds, arriving just in time for when Mei and the others in Anti-Entropy arrive, and he also improves his powers and strength.

Arc City arc: After Kiana was sought for what happened, he and Mei try to help to get back with Kiana. He helps and accompanies her at all times, learning better about his powers and strength. Then he meets Kiana crying with happiness, both of them, but she still must save the others from that bomb that would kill everyone. After that, Durandal arrives, but Espartan fights fiercely against her, although he ends up losing and being captured by Durandal, giving Mei the option to take Kiana, and Espartan also manages to buy time for himself to escape.

Elegy to Yesterday: After Espartan is captured and taken to Schicksal, Mei, with Bronya's help, saves him with a plan executed thanks to Tesla and Einstein, and Theresa, who helped them in secret, to finally fight Durandal. But after seeing that everyone was fighting for the same thing, they made peace, and Durandal withdrew since Kevin had appeared. But Kiana was still not improving, so Mei had no choice but to decide to go with Kevin after he spoke with Mei about going to World Serpent and awakening her Herrscher to save Kiana. Espartan does not agree with Mei joining Kevin, and he tries to persuade her, but she does not allow it despite being his little brother; she must save Kiana, who was now very weak. And after they tell her that if she joins World Serpent, releasing her Herrscher to save Kiana, then she does not hesitate. They fight, and Mei wins, but before she leaves, Espartan, in tears, begs her to please let him go with her, not to leave him, and that he will help her because he loves her; she must know that he will be fine and that in the future she knows all this will only be a horrible passing memory. Mei did not want to take him to World Serpent; she knew it was wrong, but he begged her with his life to please go with her, and it was... It was her little brother. Mei accepted, and Espartan went with her on her back to World Serpent.

World Serpent: After arriving there with Mei and seeing that World Serpent was not as bad as it seemed, and that they also showed him the Elysian Realm, where Mei and Espartan help the Flame-Chasers, and they also help Mei and Espartan through information about the Honkai. But after the Herrscher of Corruption appeared, Espartan and Mei decide it is time to leave. While the Flame-Chasers deal with the Herrscher, and Espartan got along wonderfully with Elysia, unfortunately everything is destroyed, and the Flame-Chasers die along with the Elysian Realm and the Herrscher of Corruption. But Mei and Espartan are finally ready to return to Kiana, since Kevin had also left World Serpent and the Elysian Realm to continue his evil plan.

Perhaps Hell is Full of Love arc: After Mei and Kiana finally made peace, and Kiana defeated the Herrscher of Domination and obtained a new Herrscher of Flamescion power, Espartan had a restlessness and pain in his heart. Sirin... She was still alive inside Kiana, although supposedly she was dead; that is a lie. Kiana is Sirin, and Sirin is Kiana. Espartan begins to investigate, and through his own Herrscher of Rock power he finds ways, and finally, after a long time and having risked his life to get a physical and spiritual body through the Honkai and his own Herrscher of Rock power—for whom? For Sirin. The only thing that had to be done was for Kiana to bring Sirin out of her body. No one, absolutely no one, wanted that, even Kiana, who knew what Sirin went through, did not want to risk it. Sirin killed millions and was also evil. Espartan knew he could make her change, that he knew her, and that if they trusted him, he could do it. Although they all disagreed, they trusted him reluctantly, except Mei, Bronya, and Kiana, who truly had hope in Espartan although they did not support the plan. And after separating the Herrscher of Void with the Herrscher of Flamescion, with Kiana, they could finally free Sirin from Kiana. She entered in a rage, fury, and hatred as soon as she returned, but... When she looked fixedly at Espartan, she could not attack; she simply stood paralyzed while Kiana was agitated and weak from having been separated from Sirin, and Mei helped her. Sirin, in a fit of rage, attacks Espartan with her void needles and disappears. Espartan recovers quickly and goes with Tesla to tell her where Sirin is now. Mei, still with Kiana in her arms, lets Espartan go for Sirin thanks to Tesla's data. Espartan opens a portal and goes with Sirin. After a talk where Sirin did not understand how he, after suffering the same as her, was now on the humans' side, while Espartan tried to make her see reason, reminding her of her family and friends but also of him at his most vulnerable moment. But Sirin did not want to be deceived; for her, this was just brainwashing her little brother; she had to free him from his prison... Espartan realized this and quickly faced Sirin. She understood this as a war cry, and both fought fiercely, where in the end Espartan wins, but it is because he let himself be attacked at the last moment and sincerely hugged Sirin even after Sirin seriously wounded him. He did not hurt her; he only... hugged her. Sirin did not understand why... Why him? After everything I took away, Himeko, taking away Kiana's health and life, and killing innocents who for her were insects. Espartan confessed that he knew that was wrong and that the people she killed could never come back, but he forgave her. But he only wished that Sirin could live a normal life like any girl. He then made her doubt and understand things she did not see before, and now she hated it because it made her feel guilty, but Espartan was not going to give up so easily. In tears, Espartan confessed to Sirin how much he loved her and wanted her to live a normal life as she always should have, that please let him help her because he did not want to see her continue sinking into this sea of pain and loneliness. She already had too much of that in Babylon, and... Although they are not the same. And Espartan's goodness and even naivety is too much at times, but it does not mean Sirin cannot change or cannot have a good life in the end. He would rather die before continuing to see Sirin become something she is not... Maybe if another human, person, Herrscher, or whatever told her that, she would kill him without mercy, but it was Espartan. Deep inside, she loves him, but she does not want to accept it, but it is so difficult. So Sirin reluctantly accepts, telling him that most likely in the end they will be enemies again, and Espartan accepts without problems, sure that he can save her. Espartan told her to please let him show her the beauty of this world, just as he once did not know many things and now knows and understands them. More than anything, he wanted Sirin to see them too. He also "promised" her that he would do everything possible so that she could be on the Hyperion since she destroyed St. Freya. And basically Espartan shows her beautiful things there are in the world, and they even go to a city where she eats ice cream, leaving the vendor alive whom Sirin wanted to kill with Espartan's help, and finally reminding her that he was her little brother and that she was his first Onee-san. Sirin, after everything he showed her and seeing that Espartan's heart was not only healed but had also become a much better person than she remembered, something in her heart broke. She hated humans and wanted to kill them still for everything they did to her, but he was also right; the scientists... they died, and the others are only guilty for not arriving in time or being related like... "Why do ice creams still exist?" Because children eat them; are they to blame? Yes. But that does not mean they should be blamed for all the machines, ingredients, and elements with which ice creams are made in factories. Sirin could not erase anything just like that, and Espartan told her she should not; that she should remember. Remember, then, and thus in the future she will know what to change. Deep down she is just a girl who wants a family, and Espartan was someone who also wanted one and now had one. Sirin did not care much about the Valkyries either, maybe Kiana... Although surely she hates her too because of Himeko, but she would really be willing to try as long as she keeps that little boy by her side. The only one who truly... Even after everything she did and did to him, chose to forgive her and love her. Both hug in tears. Only Espartan matters to Sirin, and if with him she can finally eradicate that hatred toward humans, then she will do it. She will do it until Espartan is the happiest child with her, because she knows very well how much he loves her, and she does not want to disappoint him, she does not want to disappoint herself by losing... Losing the last truly good and pure thing that has come out of this world.

Sirin arc 2: After what happened with Sirin, Espartan returns with her to the Hyperion. She hated Schicksal for what they did to her, and also Otto, although everyone there did. The Valkyries and other personnel on the Hyperion barely felt Espartan's presence when they all went there, including Mei, Bronya, and Kiana. All of them with their Herrscher weapons ready; Sirin also activated hers, but Espartan stood between them and defended Sirin despite the scoldings from the others, including Mei's. She told him to please come toward her and not get close to Sirin. After arguing a little, both lower their weapons. And Espartan explains to them that Sirin promised she could change if he helped her have a normal life. With Espartan's characteristic way of being, all of them underestimated him—not because he was a child, but because of Sirin. How could he...? Make a Herrscher who killed millions and Himeko change...? The friction is very clear, and the first days are very hard, since Sirin does not adapt very well to having a room for herself and starting to try not to use her powers. He helps her; sometimes they even sleep together and he tells her stories, and they also do more... more childish things sometimes. And that makes her return to when not everything was horrible. Meanwhile, Sirin also tries to socialize with the others at Espartan's request, and he tells them to also try for Sirin, although he tries to force something. They all know what Sirin suffered, but sometimes even if you suffered a lot, some things are unforgivable. That is why Espartan is so special to her. He not only lived with her through incarnate pain but also forgave her. Thanks to Espartan, Sirin manages to have that normal life she so desired again; she studied and had hobbies like making dresses very well in such a short time, and Espartan told her that if she keeps it up, she will probably be a great and renowned seamstress in the future, but she denied it, saying that when that happens she will have already destroyed the world—but internally Sirin wanted those words to be true. She is happy... Happy with him. Maybe he is not her mother. Maybe he is not her friends, but he is... Her little brother. Maybe not by blood, but she sees him that way. And it is more than enough... He tries, she loves him, although sometimes it is difficult to accept because she cannot leave behind what she is or what she is trying not to be anymore... Since little by little she also gets to know the Valkyries of the place and sees that most of them also have hard stories of origin and each one in her own way coped with things. Although Sirin was still really the one who suffered the most—Sirin and... And Espartan. She finally, after a long time in the Hyperion, basically accepts her life there. Achieving what no one could—changing Sirin by giving her that normal life that a girl her age desired, although with a little magic sometimes... Although this would create another problem. Sirin felt guilt... Now that she understood and saw things differently and the other girls began to grow on her, she... Began to see all the horrible things she did, the deaths, her attitude, her way of wanting to destroy everything. And that made her fall into several moments of sadness, feeling unworthy of feeling that she deserved this after everything she suffered...

One Last Apology: After Sirin began to feel guilt for the people she killed before, it made her feel a great and enormous emptiness, since she still hated humanity but did not want to eradicate them. She realized the innocent people she killed, families. This made her fall into strong depressions of self-loathing that little by little isolated her from the others, although Espartan did not give up on her even when Sirin already had. It turns out that Otto did not expect Sirin to be able to change or try to change, and moreover that they would take her out of Kiana's body. He underestimated Espartan, but beyond that, it meant a problem for his plan if Sirin was on their side. Since he still needed time to carry it out, and Sirin with her void power could alter something or ruin everything outright upon knowing how much she must hate him. So Otto makes a plan to finish off Sirin: he generates some powerful Honkai attacks in different parts of the world, separating all the girls and Espartan, leaving Sirin alone there with the help of some Divine Keys combined into an abomination made to kill a Herrscher, and he takes her to a plane of the Herrscher where he will kill Sirin. But before that, he reminds her of everything, every detail of what she lived through in Babylon, since one of the keys connects to Sirin's mind, then all the people she killed, and then... There is nothing more. Trying to break Sirin's mind, making it clear to her that she will never change. At that moment Espartan enters the plane because he had placed a protective mark on Sirin, and he makes her see that it is not like that, that right now she felt a lot of guilt but that she knows it is not like that. There is more... Then she remembers how, from that moment when she saw Espartan again, that second when she came out of Kiana's body and saw him. From that instant she managed to be a better... A better girl. Sirin then uses her guilt against the Herrscher. Remembering them... As Espartan said, and doing something, something much better to demonstrate that she can change and be a better person. Sirin then awakens the Herrscher of Hope, a Herrscher with a warm appearance, with roses and purples all over her body wrapped in a beautiful dress. It symbolized a forgiveness she had given herself; no one would come back, and she did not change just like that either. She accepts her current destiny, hating humanity but fighting for the desires of those who truly love her and want her. If her path continues forward, she wishes that she can truly forgive herself with humanity someday, although right now that is impossible. But hope is never 0. The Herrscher of Hope was not only a change in Sirin but the living image that she has hope—she has hope again—and as long as she keeps living, the hope of one day a tender, loving, and warm day of a normal life as Espartan promised her will always be a possibility. She had evolved into a better person, and thanks to Espartan's words of encouragement and the support of the others upon knowing that they tried to protect her this time... She manages to defeat the Herrscher. After that, Sirin is honest with Mei, Bronya, and Kiana in tears, apologizing for everything, telling them that she did not know what to do, she only felt hatred and still does, but now she wants to be with them. That please let her—not forgive her, but let her be with them. The three accept and forgive her, telling her that if Espartan trusts her, then they do too, and if Espartan loves her as family, it is because that is how it is. They all hug, and finally Sirin's evil life arc is left behind, recovering her life and also becoming a Valkyrie to protect humanity this time, even if sometimes she does not want to do it; she knows that in the future she might end up growing fond of them. Maybe...

Demon Arc: Right after having saved Sirin from herself and her having decided to help humanity and the Hyperion from now on, Espartan suffers quite a few discomforts and nightmares that no one knows how to treat. Everyone in the Hyperion is anxious and desperate since they do not know what the hell is happening to Espartan. It is then that one day his demonic power breaks loose, causing a lot of havoc in the Hyperion, but his Onee-sans manage to neutralize it, though by hurting Espartan a lot. It is there that they all finally realize what is happening after so long—the origin of Espartan, where he came from; that too-pure evil awakened in him. It is there that Espartan tries to fight that demon or being that tries to take control of him, since he felt he could no longer bear the presence of that being that disturbed him, that caused him nightmares and horrible visions of his Onee-sans dead. Since everything had been good and warm for Espartan, but deep down he suffered in silence so as not to worry them. It does not mean he did not feel all that love or innocence—on the contrary, he felt it more than anything—but he made an effort not to give so much importance to something that in the end escalated to something much worse. The demon, seeing him so happy, wanted to take away that moment and destroy not only its bearer Espartan but also all existence along with his Onee-sans for real this time, so as to break him once and for all. Espartan defeats the demon and pulls it out of his chest, and he does not die thanks to his body now being a Herrscher's, but it quickly goes away to the Babylon Tower, or rather its ruins, killing thousands of innocents along the way and absorbing the blood of all of them, since it absorbs everything regardless of whether it is a Herrscher or not. So he does not want to put his sisters at risk, and on a day when they were all asleep in his bed, he teleports to the Babylon Tower. His Onee-sans quickly try to get to him as soon as they noticed his teleportation. Why the Babylon Tower? Because he wanted to absorb all the remaining Honkai energy of that tower—not only the Honkai but all the pain that happened there—which he does, and with it the demon tries to kill Espartan with a beam of Honkai energy and blood power. But Espartan activates his Herrscher of Planet at that moment upon discovering in that instant that his life does not depend on that being. They may be the same and come from the purest evil, but he is Espartan Jagami, not a Demon. Espartan with his new powers tries to kill the demon, but even so it is too strong. It is then that not only Mei arrives but also Kiana, Bronya, and Sirin to help him destroy the demon, and among the five of them they launch a combined planetary beam with Sirin's void, Kiana's fire, Bronya's technology, and Mei's Honkai lightning, and all of them finally kill the demon that Espartan had kept inside him for so long, demonstrating that his destiny is not written by his "true being" or by what he was destined to be. He is Espartan Jagami, and he does have a family—all his Onee-sans—no matter how much he denied it or tried to admit it. He may have come from absolute nothing with a purely evil destiny, but that never meant he had to become that thing. "There is no one he would rather be than Espartan." Although the death of the people the demon killed weighed heavily on Espartan even if it was not his fault as such—the fact that because of keeping his inner demon to himself for so long it caused that made him very sad. Fortunately, Espartan had his Onee-sans to better cope with the burden before going after Otto. They spent a lot of time with him, letting him cry in their arms, trying to cheer him up and also showing him the things he had done for them, making it clear that no matter what happens they will always support him in everything. They could not delay with Otto, but neither would they set Espartan aside when he needed them most, so they went to a bubble universe that the five of them generated with their Herrscher powers and went to a place where Espartan could rest without needing to be attentive to Otto. They stayed there for at least a month until Espartan finally managed to calm down and accept those deaths, knowing that in the future he will be more careful, and if innocents die again then he will feel very sad, but... He will overcome his pain to keep fighting like a true Valkyrie (even though he is a boy). So they finally prepare to go after Otto.

Thus Spoke Apocalypse: Otto's plan failed with Sirin, but it gave him enough time to continue with it. After that, everyone wanted to kill him and make him pay, but he would already do it for himself. Espartan still wanted to say something to Otto... But he could not that time. And Otto finally died.

Last Look at Otto Apocalypse: Espartan, somewhat sad about the imminent farewell of Kiana, goes to the train where she will leave, and an illusion of Otto is generated there. Espartan talks with him and basically reproaches him for everything, and Otto accepts it with his arrogant and controlled attitude, but in the end he tells him thanks sincerely. Otto does not understand why he is thanking him if a moment ago he was making a list of all the bad things he did, and he knew it, but that maybe if it were not for Otto, because of Babylon he would not have met Sirin. The pain was horrible and he hates remembering those things, but if that means seeing Sirin or any of his Onee-sans one more second, then he would suffer as many times as necessary. If it were not for Otto, he would not have met Mei afterward, and Kiana, Bronya, Himeko. Espartan did not justify him, but he did thank him for the fact of, so to speak, giving him his current life even if it was not in Otto's plans. Finally, he tells him that he understands what he did for Kallen; he was selfish, evil, and horrible, but that he would do the same for his family—maybe not to the point of killing left and right, but yes giving his life for any of them, just as Otto did with Kallen. Otto finally understands and realizes that maybe he was not the only special or persevering being in the world; not only Espartan but maybe many others whom he killed. He does not regret it, but he does realize that there are many more people like them who would give everything for those they love. Finally, Otto accepts Espartan's words without regretting it, as was to be expected, and at the end Espartan wishes Otto the best because despite everything he did and the lives he destroyed, no one deserved to suffer eternally, not even Otto, Kevin, or Sirin.

The Moon's Origin and Finality: After Otto died, now it was time to deal with Kevin Kaslana, since he wanted to kill 99% of humanity on the moon so that the 1% would be resistant to the Honkai and repopulate the world, since for him this is what should be done so that no one suffers again. But this was a cruel act that Kiana's team was not going to accept. So Kiana, Bronya, Mei, Sirin, and Espartan stop Kevin so that he cannot carry out his plan, all of them fighting and obtaining new powers and evolutions of their Herrschers. At one point, while they were all advancing toward the moon, Kevin tested all of them separately to be the new heroines against the Honkai: Kiana becoming Herrscher of Finality, Mei becoming Herrscher of Origin, and Bronya Herrscher of Truth. Meanwhile, Sirin in this case, the Herrscher of Miracle, being a miracle—everything that changed to finally fight for humanity even without making peace, but leaving a miracle that she finally does not want to kill them; she will simply now protect them because it is the right thing to do, leaving that small hope that her previous Herrscher had, now leaving a miracle that seemed so unlikely at any point in her life but happened. Espartan as the Herrscher of Pure Love—it is similar to Elysia's, since Elysia's loves humanity, but Espartan's is something he loves everything as such, whether it brings negative things or not. That is, the Herrscher is full of pure love without limiting himself to humanity, but also loves the earth, the solar system, and all existence, being totally naive about whom to love, even bad people, being the price of pure and naive love, even loving Kevin in the end. And at the very end they manage to defeat and kill Kevin among all of them by having their new transformations to face the Honkai in the future and saving everyone. But in the end Kiana must stay on the moon in order to eradicate 99% of the Honkai energy from the earth, saving everyone, but she has to go and say goodbye to everyone.

Da Capo: Finally, Kiana has to go to the moon. Espartan was very sad since he did not want her to go, but he knew there was no option this time. They do everything possible before saying goodbye to Kiana, and finally she leaves, fulfilling her destiny and saving humanity while Espartan stays with Mei, Bronya, Sirin, Fu Hua, Theresa, and more Onee-sans, living a normal life full of love, while Espartan occasionally visits Kiana on the moon with his Herrscher powers, since he had promised her.

Bittersweet facts...: Espartan is eternal in years due to his nature as a being of the void, and most importantly, he will continue living with his Onee-sans until their mortal time allows it, especially with Mei and Bronya, since Kiana is immortal in years although still mortal to attacks after becoming Herrscher of Finality, and Sirin is also immortal in years and can be physically hurt; she is immortal in years for being the Herrscher of the Void and also having been reborn in that new body made of pure Honkai energy. At least he will have them forever, although honestly the topic with Mei terrifies him... He knows that at least there will still be Onee-sans there for them, and very likely Kiana will share that pain with Espartan and Sirin, who will never abandon him.

Fun curiosities:

List of Onee-sans: Despite Espartan having a very great, kind, and loving love, he is very sincere, and he has a list that his sisters do not like very much about whom he loves most. In first place is Raiden Mei; in second is Sirin, something that bothers her since she would want to be Espartan's first Onee-san, being somewhat possessive and having childish friction with Mei without really reaching anything serious, but Sirin tries to get all the attention and makes an effort to make Espartan very happy to see if one day he will put her in first place (he will not). In third is Kiana Kaslana, who before Sirin returned was second, something that honestly hurts her a little. Bronya is in fourth place; she is also a little bothered by it although she does not express it much since she does not like being outside the top 3. Then there is Himeko, who was in fifth place for everything she meant to Espartan, and he really does not want to leave her there since he feels it is somewhat insensitive, but even so what he lived with her was enough to love her like a mother. Fu Hua Okaa-san is in sixth; she really appreciates him a lot, does not like waiting for affection from the most adorable and good child in the world, or maybe she has already given up. Seele is in seventh place; Seele really does not see a problem with it, she knows Espartan loves her a lot. Theresa is in eighth place, something that saddens her sometimes, and Espartan tries not to give it too much importance. Elysia is in ninth place, although Elysia is no longer there, it bothered her quite a bit since she wanted to be number 3 at least, and Espartan always denied it flatly. Tesla is in tenth, and she hates it with all her soul although she hides it; sometimes she reproaches herself that if maybe she had not wanted to kill him when they met, maybe he would love her more, although this does not matter to Espartan. And Einstein in 11th place, although she does not care much, she sees Espartan as a good friend. And so on with many more girls and Onee-sans. Espartan explains that they should not pay so much attention to his Onee-san list; he loves them all equally as such and would give his life for each one of them separately, it is just that there are Onee-sans that he sincerely cannot help loving a little more, but it is very, very little—basically the last Onee-san on his list he still loves 99%, and the others scale up with 000000000000.1%, that is, if Mei is 100% in his love, Sirin would be approximately 99.9999999.9999999.999999.99999.99999% of love, so the difference is not that big.

Relationships:

Mei: Espartan has a close relationship with Raiden Mei, as she was the one who saved him from Babylon and gave him a good and loving life along with her and the others, so he feels deep in his heart that he is in debt to her, and moreover he loves her more than other Onee-sans and he says so openly, since she is the one he loves most and the one he is most in debt to. Mei taught him to cook, dress, go to the bathroom alone, eat well, study, learn what hobbies he likes, and many, many other things. Mei loves him with all her heart and sometimes, and only sometimes, feels she loves him a little more than Kiana. Moreover, something Espartan confessed to Mei is that he sincerely sometimes feels a little jealous of Kiana, but then he remembers that he also loves Kiana and better loves them both as if they were one. Basically they have a perfect and very close older sister and younger brother relationship.

Sirin: Espartan and Sirin, as already seen, are extremely compatible, clingy, and close because of everything they lived through before in Babylon and then because Espartan saved her from herself and helped her become a better and good person who could change—not for the common good but for her own. It was then that Sirin managed to change only for Espartan at that moment, and then for the other girls and Valkyries, and then for humans, although she still does not accept all of them since there are evil people; she tries to do it with most, especially those who have families. The relationship between Sirin and Espartan could be said to be closer than the one he has with Mei because of everything they lived through, and he tells her that maybe if they had found each other like that before—that is, if both had gone to the Hyperion and been saved from Babylon—she would be his number 1, since he could not deny to Sirin that Mei is very, very important to Espartan's life. That does not mean he does not love Sirin even a little less; rather, Sirin is one of the most important people in his life; he would sacrifice a lot for Sirin. Sirin and Espartan are the definition of perfect siblings. They both support each other and sometimes one depends on the other, although this happens more with Sirin since she is very attached to Espartan. For her, he is sincerely her number 1 in everything, absolutely, even more than her mother, who occupies a 2, although it hurts her to admit it, since Espartan sacrificed a lot for her and really, despite everything, is the only one who saw beyond the Herrscher of the Void. And she could not be more grateful with life, if life's gift to her was not only the best little brother but the best being that has ever existed. Words that she only truly feels with Espartan, even sometimes somewhat exaggerated, but it is understandable after living such a horrible life and having him support her so much and still supporting her; it is something she knows not everyone deserves and she fortunately has. She may get angry, grumble about not being number one in love, but that second place... of that being who really did so much for her that she almost killed him herself upon reuniting is something Sirin knows is not a normal love. If that is being "second" place in Espartan, then it is the best place she could ever have.

Kiana Kaslana: Espartan and Kiana are more like two younger siblings, only Kiana is already an adult... She is fun, clumsy but loving and mature when needed. Kiana is someone very important to Espartan since she taught him other things; from Kiana he learned to never give up and to be a better and more powerful person for others. Espartan knew how much Kiana and Mei suffered through all the arcs, but he always watched over both of them and never left Kiana behind when Mei tried to forget when they were in the Elysian Realm. Kiana was a very good figure for Espartan, because thanks to her he also saw the other side of the coin, the other sides—how many there were exactly, he did not know, but quite a few. The world was not rainbows and flowers, but there was love and beauty in it, something that Kiana and Espartan mutually shared: a very great love for the existence of the world itself. Moreover, Kiana really was that point of inflection between the loving and maternal Mei and the crazy, youthful, childish, and silly older sister Kiana, giving him one or another bad habit that Espartan learned from her. Basically Kiana formed a large part of Espartan's life, and besides being also someone who suffered because of what happened with Sirin, he felt empathy not only for Sirin but for Kiana, since they did not deserve to suffer that way, both of them. Despite that, Espartan visits her from time to time, making it clear that the Onee-san list is not very important.

Bronya Zaychik: Espartan and Bronya were quite close from the moment they met, since Bronya taught Espartan video games and he quickly loved them, becoming very good siblings. Bronya for Espartan was a very good way to learn about himself since she was not very sociable and it was difficult to decipher what she felt, so the dynamic between them was warm and tender when he tried to make her learn with innocent things and words, while Bronya, who was not stupid, could do little or nothing with her expressionless tone. She also accompanied him in the Sea of Quanta for Seele, who also became an Onee-san. Bronya was basically a very good sister, being the middle point between Mei and Kiana with tranquility and calm fun. Moreover, Espartan also saw in her that she was not inexpressive just because that was how she was, but because of many things she suffered in her past, empathizing with Bronya and helping her cope with things that would be very difficult for her alone. She later grows a little in social matters and they become very good siblings, playing many times or doing technological things that Bronya taught him. Basically Bronya was very important to Espartan by demonstrating with her that he could help more than expected, and this was important for later helping on his own or solving things that not even his Onee-sans could do by themselves.
