Kiana Kaslana

Kiana Kaslana is one of the main protagonists of Honkai Impact 3rd along with Raiden Mei and Bronya Zaychik. She is the adoptive daughter of Siegfried Kaslana, alongside being a vessel for the 2nd Herrscher — Herrscher of the Void.

In her casual state, Kiana has messy white hair that's often tied into two big braids. Normally, her eyes are a bright sea blue, which is in contrast to the quiet, yet deadly, golden eyes of the sleeping Herrscher within. She is 163cm tall and weight 49kg, she is born on December 7, 1998.

Kiana Kaslana, or K423, was at first (and in some ways, still is) a very boastful, overconfident and "idiotic" girl who took a great liking to food. She was happy-go-lucky, and confident she could do anything she set her mind to. She often smiled, even if she was injured, and adored the company of her friends, whom she showed great affection to. Her happy-go-lucky attitude and her overconfidence often caused her to make reckless decisions without a second thought, especially if it was to save others, even if it meant sacrificing herself.

Kiana and Mei have a special bond unlike anyone else's. Both of them were tossed aside by fate, and thrown into their own perspective chaos. But when they met, they were no longer alone in the world. Kiana has always been open about her romantic feelings for Mei. Mei usually scolded her for being too open about it on missions.

As a child born with no mother, and with a father that left her, Kiana naturally gravitated towards Himeko. At first, she was prickly. She thought that as a Kaslana, she was invincible, but Himeko proved her wrong by defeating her in a duel. After this, Kiana began respecting Himeko more. One time, on Fathers Day, Himeko found Kiana moping about the campus. Even in her drunken state, Himeko could tell something was wrong, so she asked Kiana about it before being brushed off. Eventually, though, Kiana admitted she was thinking about her dad. Himeko gave her a speech about her own issues in the past before bringing Kiana into a hug. Kiana protested, but let her do so. It's been shown various times that Himeko was a big pillar in Kiana's life. From changing her perspective on what it meant to be a Valkyrie, to her eventual final lesson, Himeko guided Kiana down her path. Kiana often called her 'Auntie', much to her chagrin.

Born on December 7th 1998, Kiana Kaslana was a carefree, bright and playful child. However, her family was torn apart as the Second Honkai War ravaged the land, and with her mother dead, and her father a fugitive, Kiana was taken by Otto Apocalypse to be examined. Otto kidnapped her to study the Kaslana genes and figure out how Siegfried got his powers. When he was unsuccessful, he instead started making clones of her, with the intention of using one of them as a vessel to bring back Sirin (the 2nd Herrscher). This was successful with clone K-423: in which the core was implanted during growth, with Kiana Kaslana's DNA infused within. The clone developed a consciousness and became sentient, unlike all the other attempts.

Presumably living with Otto for quite some time, K-423 was eventually taken back by Siegfried in 2007. Siegfried tried to bring both Kianas (the original and the clone) with him, but lost the original in the confusion and rush. He managed to escaped and fled to a cabin in the woods, where he and K-423 lived for three years. During this time Siegfried was still grieving for his losses, and refused to acknowledge the clone as his daughter. He gave her what she needed to survive, and gifts on her birthday, but otherwise ignored her. K-423 was lonely, but she still cared for him very much, tending to Siegfried's wounds when he'd go out and fight the Honkai.

One day, Siegfried came home heavily injured from fighting Honkai, and collapsed inside the cabin. K-423 wanted to help him, so she grabbed the Shamash guns and went outside, where she found a Templar class Honkai beast. Right before it stabbed her with its lance, Siegfried smashed its arm and kills it. Touched that K-423 wanted to fight the Honkai, he acknowledged her as a Kaslana and gives her the name of his daughter, Kiana. Kiana fondly remembers this moment, calling it the best birthday gift he had ever given her. The two make a pact to “fight for all that’s beautiful in the world”. One year later (2010), Sirin woke again, forcing Siegfried to put her back to sleep, losing an arm in the process. Siegfried left Kiana for unknown reasons, leaving her to wander the planet looking for him. She traveled to many countries in her search, including Italy, Haiti, and the Philippines.

This eventually led her to Chiba academy in Nagazora (Honshu, Japan), where she met Raiden Mei. Kiana reached out to the girl, and despite Mei's reluctance, the two quickly became friends. Kiana eagerly hung out with her, eventually freaking out when she tried Mei's homemade cooking. She begged Mei to make food for her as well, since any time she tried to cook it would end in disaster. Mei agreed to her ridiculous list of food requests, and began making lunches for the both of them. Kiana also stood up for Mei when others would bully and mock her, despite the rumours that they spread about Kiana as well. She frequently repaid Mei in whatever way she could think of, even giving her the only umbrella she had in a downpour. When Mei asked Kiana why she reached out to her with all the rumours of her father, Kiana only said that "Mei is Mei", no matter what her father may or may not have done.

The two found solace in each other, and were no longer as lonely as before.

Kiana and Mei lived peacefully until the latter unexpectedly rose as the 3rd Herrscher: the Herrscher of Thunder. Her eruption sparked a huge amount of Honkai energy accumulating; turning everyone but Kiana into mindless zombies. Kiana fought against the personality that took over her friend, and eventually defeated her. When Mei awoke and tried to commit suicide, Kiana grabbed her hand and told her not to give up. After coaxing her to reconsider, Kiana was able to pull her up. The two of them traveled Nagazora for some time before running into Bronya Zaychik, who joined them in their journey to escape the city.

There is another version told where Mei and Kiana only meet after the former became the Herrscher of Thunder. In this version Kiana is as persistent as ever, not giving up until she can "save" Mei from the Honkai. This version's Herrscher personality is the one who decides to jump off of the rooftop, afraid of Kiana's kindness. In the end, she still takes Kiana's hand.

One day, when the three were fighting against Honkai, they ran into an unusually big swarm of them. Bronya was thrown through a few buildings in the confusion, and Mei was too worried about her to notice an Emperor aiming for her. Kiana noticed, however, and pushed her out of the way, taking the blow for her. The two fell to the ground, Kiana bleeding out before Mei's eyes. The immense emotional stress caused Mei to erupt, which alerted Schicksal with the massive spike in Honkai energy. Schicksal sent their battleship Hyperion to investigate and put down whatever caused the spike. This team, led by Murata Himeko, arrived and tried to fight off the Herrscher personality. Unfortunately, it didn't take long for her to decimate a big portion of the ship. Kiana awoke during the fight, and broke Mei’s Herrscher wings in an attempt to get the normal Mei back. She fell unconscious soon after.

Kiana wakes up in the St. Freya medical ward, where she meets Theresa Apocalypse. Theresa makes a deal with Kiana: if Kiana enrolls in the academy and becomes a Schicksal Valkyrie, she will tell her where Siegfried is. Kiana accepts only after knowing that Mei is safe.

Kiana's overconfidence was challenged constantly at St. Freya. From the first day of training, to her first test, Kiana finds that even though she survived alone for so long, there were things she wasn't good at. Bronya decides to help her out with her remedial exams and sets up a virtual reality link so Kiana can learn history visually instead of using textbooks.

They go from the first recorded instance of animals infected by the Honkai (2717 BCE) to the 14th Century, and in that virtual reality, Kiana sees the Oath of Judah sitting out in the open. Curious about it, she places her hand on it. All of a sudden it recognizes her as a member of the Kaslana house, and pulls her into another virtual space. She falls from the sky and into the arms of Kallen Kaslana. The two can barely begin talking before a group of people in black robes appear.

They questioned her motives for leaving them, and Kallen simply said she wanted to save Kiana. While some of the guards didn't believe her, one in a more detailed mask stopped their complaints. The masked figure asked Kallen to make a confession so she wouldn't be executed, but Kallen refused.

One of the guards responded by tugging at her chains harshly, and Kiana kicked the assailant in retaliation. While boasting, she was attacked by another one of the masked figures and blacked out.

Kiana awoke in a prison cell with Kallen across from her. They introduced themselves and chatted for a bit: Kallen saying the masked person who took Kiana down was Lord Arthur, who formerly trained her. Kiana asked why she was in trouble, to which Kallen responded that she stole something. Kiana excitedly compared her to Robin Hood (aka stealing to give to the poor), but Kallen told her she had simply stolen an ancient artifact from those who wanted to use it for their selfish gain. Afterwards, she swiftly shut down discussion.

Kiana awoke the next morning to the message that her "mother" had been sent to pick her up. She was confused, but asked Kallen if she would be okay alone. Kallen reassured her before the prison guard shoved Kiana away from the cell. It turned out Bronya was pretending to be her mom, and had hacked her way into the data space Kiana had fallen into. Bronya stated it was a hidden sector of the memory archives only available to those of the House of Kaslana, and that she had some trouble getting in. She also mentioned it was advanced in the sense of having hyper-realistic and interactive feedback settings.

When Kiana brought up Kallen, Bronya told her that that was her ancestor: Kallen Kaslana. They had learned about her in history class, but Kiana hadn't been paying attention. Basically, she was the top Schicksal valkyrie before stealing a black box containing a Honkai Core (specifically belonging to the Herrscher of Corruption). She ran away to the Far East, where she fell in love with Yae Sakura, who was eventually corrupted by the being in the box Kallen stole. She was forced to seal her away.

She was brought back to Europe for questioning and in trial declared that she was in love with Sakura, and that she was an innocent person. Kallen was sentenced to death by hanging. Kiana seethed at this new information, saying that those corrupted by Honkai were once human, and they aren't at fault for being misled by it. She said that loving a Herrscher isn't a sin.

Kiana declared they should save Kallen. Bronya said that was ridiculous since this was a VR world, and that Kallen Kaslana was long dead in the real one. This didn't perturb Kiana, however, and she insisted it was the right thing to do. Bronya gave in, and they started planning how they would save her.

The plan was to set off explosives as a distraction. Kiana would take advantage of the confusion to defeat the masked people and save Kallen.

The day of the execution, everything was going as planned up until Kiana swooped in. Suddenly, Lord Arthur pointed them towards the harbor, where he had arranged ships to take Kallen to somewhere safe. All seemed to be going great, until large and unusual Honkai Beasts swarmed the city. Otto arrived, explaining he had set them loose from the underground facilities Schicksal carried them in, and was doing it to save Kallen.

Kallen slapped him and pronounced she would defend the citizens instead of going with him. Kiana joined in her efforts, but they were fruitless. Kallen saw a beast going for a child and stepped in, taking a huge spike through her stomach in the girl's stead. Kiana tried to fight back, but without weapons it was useless.

Bronya rushed to get Kiana and herself out of the simulation, when she fell from her vantage point. The real Otto Apocalypse caught her. He was impressed with the two of them, and decided to let them have access to data for the Godsbane Battlesuit: Knight Moonbeam. The suit was deployed onto Kiana and she easily defeated all the beasts that attacked the town.

Afterwards, Kiana comforted Kallen, saying that everyone was safe. Kallen thanked her, saying that as a VR character, it was unexpected to be treated so kindly. She went on to say she realized after a while that she was a VR character due to the repetitive script and being killed again and again in the same way. Kallen thought Kiana's appearance might change something, but that didn't seem to be the case.

Kiana told her the real Kallen had died more than 500 years ago and VR Kallen responded that Sakura must've been alone for that long, too. She asked Kiana to send a message from her to Sakura if they ever met. This message is not revealed to readers, but after hearing it, Kiana says her ancestors are just as dumb as her.

While Himeko was in her coma from an accidental stigma spike on the Chiyou mission, Kiana was left distraught. Sitting outside, worried, Kiana experiences a hallucination to which she meets her father, who strangely shoots her with the Judgement of Shamash, calling her monster that must be silenced. She immediately comes to her senses after being called a monster, and rushes to eat dinner at the dorms. The trio eats dinner with Kiana eating with a heavy heart, until Theresa comes and shares the good news: Himeko is on a good path to recovery.

The next day, Kiana does a virtual simulation of training that scans Kiana's brain for potential enemies and creates images of them, with a new battlesuit that is only given to B rank Valkyries, White Comet (which interestingly becomes her staple battlesuit later on). She defeats all the images summoned, with the last one supposed to be Mei as the 3rd Herrscher, however the 2nd Herrscher inside of her unconsciously alters it to be Siegfried, hinting that the 2nd Herrscher is afraid of Siegfried.

While fighting Siegfried, Theresa receives news that Mei has been attacked by a clone of the 1st Herrscher, with Mei disabling the bomb that should've blown her up if the Herrscher's will awakened. Upon hearing this, Kiana demands "Siegfried" to let her go, to which he refuses, saying that Mei is the 3rd Herrscher, stating that the Kaslana oath is to defeat the Honkai. Kiana suddenly remembers everything that occurred 4 years.

When Kiana is caught off guard, Siegfried unites the two twin guns into its Zweihander form, which shocks Theresa as she realizes that Kiana has seen the Judgement of Shamash in its complete form before. In her distress, Kiana remembers the words her father told her: "We're supposed to do whatever we can to protect those we love", and stands up to Siegfried. Siegfried surrenders, and tells Kiana to go save Mei.

Kiana in fact, arrives just in time to save Mei and even fights the 1st Herrscher clone, with her almost dying due to White Comet running out of battery. Just as the clone was about to land his blow, Mei opens a global time fracture which gives the two enough time for Mei to recharge Kiana's white comet with her Honkai power, allowing Kiana to fuse it into Moonbeam Empress and shoot a lasting blow on the clone. The two are then, finally left in safety.

Moon Shadow occurs one month after AE invasion, with Anti-Entropy making yet another Welt Joyce clone that assisted Dr. Magi in retrieving the Gem of Serenity from Schicksal. The two stay at Singapore to hide, and so Otto sends Fu Hua to take back the Gem of Serenity, alongside asking to bring Kiana along so that Otto can see how much his replica has progressed. Fu Hua disguises this as a mission to allow Kiana to get bonus points for her lowly grades.
