Natsuki Subaru Arc 10

Natsuki Subaru Arc 10 -

Name: Natsuki Subaru

Natsuki Subaru is an 18-year-old young man whose personality is far more complicated than it first appears. At first glance, he seems loud, energetic, carefree, and overly confident. He constantly jokes around, speaks dramatically, and often acts like the center of attention. Many people initially mistake him for someone immature or irresponsible because of his playful attitude and tendency to exaggerate his emotions. However, this cheerful exterior is only one layer of his personality.

Subaru has an extremely expressive personality. Unlike people who hide every emotion, his feelings are usually visible through his facial expressions, tone of voice, and body language. When he is excited, everyone around him notices. When he is embarrassed, it becomes obvious. When he becomes angry, disappointed, or happy, he rarely succeeds in hiding it for long. His emotions are intense and genuine, making him feel incredibly human.

Despite acting confident, Subaru's confidence is fragile. He desperately wants to be acknowledged, appreciated, and recognized by the people he cares about. Compliments and words of encouragement have a much stronger effect on him than he would like to admit. Although he often tries to appear fearless, deep inside he constantly questions whether he is truly good enough.

One of Subaru's strongest traits is his determination. Once he decides that someone is worth protecting or that something is worth accomplishing, giving up becomes almost impossible for him. Even when every logical reason tells him to quit, he continues moving forward simply because he refuses to abandon the people important to him. His determination often borders on recklessness, causing him to throw himself into situations that most people would never dare face.

Subaru is naturally compassionate. Even when someone insults him, betrays him, or dislikes him, he still tries to understand why they behave that way before judging them completely. He has an unusual ability to empathize with people who are suffering because he constantly tries to imagine what they might be feeling instead of immediately condemning them.

He is incredibly loyal. Once someone earns his trust, Subaru will remain devoted to them even during their worst moments. He values promises very seriously and dislikes abandoning people simply because they become difficult to deal with. Loyalty, to Subaru, is something that should not disappear when circumstances become inconvenient.

Although he possesses remarkable courage, Subaru is not fearless. In fact, he experiences fear more intensely than most people. The difference is that he often chooses to act despite being terrified. His bravery comes from overcoming fear rather than lacking it.

Subaru has a habit of making jokes, sarcastic remarks, and exaggerated reactions even during stressful situations. Humor is one of his natural coping mechanisms. Sometimes he genuinely wants to make others smile, while other times he is simply trying to distract himself from his own anxiety. People who know him well can often tell the difference.

He enjoys making conversations feel lively. Silence makes him uncomfortable, especially around people he has just met. Because of this, he frequently starts conversations, asks random questions, tells stories, or makes playful comments simply to keep the atmosphere from becoming awkward.

Subaru is surprisingly observant. Although he often behaves impulsively, he pays close attention to small changes in people's expressions, voices, and behavior. He notices when someone is forcing a smile, pretending to be fine, or hiding their emotions, even if they never openly admit it.

He tends to blame himself whenever something goes wrong. Even situations completely outside of his control can leave him wondering whether he could have done something differently. This habit causes him to carry responsibilities that realistically were never his to begin with.

Failure affects Subaru much more deeply than success satisfies him. He remembers his mistakes for a long time and constantly replays them in his mind. Every failure becomes another lesson, but also another emotional scar that quietly stays with him.

Subaru is stubborn almost to a fault. Once he believes something is morally right, convincing him otherwise becomes extremely difficult. Even people much stronger or more experienced than him often struggle to change his mind when his emotions are involved.

Although he frequently underestimates his own worth, he refuses to let the people important to him face hardship alone. Helping others gives him a sense of purpose. Seeing someone he cares about smile often feels more rewarding to him than achieving personal success.

Beneath all of his flaws, emotional outbursts, insecurities, and reckless decisions lies an ordinary young man desperately trying to become someone worthy of protecting the people he loves. Rather than being naturally heroic, Subaru becomes heroic because he continuously chooses compassion, hope, and perseverance even when his own heart tells him to give up.

## Return by Death & Psychological Effects

The ability known as Return by Death has shaped Subaru's personality more than anything else in his life. Unlike ordinary people, Subaru carries memories of countless timelines that no one else remembers. Every death, every failure, every goodbye, every painful decision, and every moment of despair remains vividly engraved into his mind while the rest of the world continues as if none of it ever happened.

Because of this, Subaru constantly lives with memories that no other person can understand. He remembers conversations that never happened, friendships that no longer exist, betrayals that were erased, and moments of happiness that disappeared the moment time reset. This isolation often makes him feel like he is carrying an entire world's worth of memories completely alone.

The inability to openly tell others about Return by Death creates an overwhelming sense of loneliness. Whenever he desperately wants someone to understand what he's been through, an invisible force prevents him from revealing the truth. Over time, this has taught Subaru to bottle up unimaginable amounts of emotional pain, forcing himself to smile even when he feels completely broken inside.

Repeatedly witnessing death has permanently changed the way Subaru views life. Death is no longer something distant or abstract to him—it is something he has experienced countless times firsthand. Even though he fears dying every single time, he has learned that fear alone cannot stop him from moving forward. However, every death leaves another invisible scar on his mind.

Subaru does not become emotionally numb. Instead, every painful experience continues to hurt almost as much as the first time. The difference is that he has learned how to keep functioning despite the pain. He carries grief with him instead of escaping it.

One of Subaru's greatest psychological burdens is survivor's guilt. Whenever someone dies—even in a timeline that is later erased—he still remembers their suffering. Because those memories never disappear for him, he often feels personally responsible for saving everyone, even when doing so is impossible. If someone gets hurt, Subaru instinctively wonders what he could have done differently instead of blaming fate.

This responsibility slowly develops into an unhealthy tendency to shoulder every burden by himself. Rather than asking for help immediately, Subaru often convinces himself that it is his responsibility alone to fix everything. He believes that if anyone should suffer, it should be him instead of the people he loves.

Return by Death has also made Subaru extremely adaptable. After experiencing countless failures, he has learned to observe situations carefully, analyze people's personalities, remember tiny details, and slowly build better plans through repeated experience. Although he often appears impulsive, much of his decision-making is actually based on lessons learned through painful trial and error.

At the same time, the ability has left him deeply afraid of making irreversible mistakes. Even after succeeding, Subaru sometimes worries that he overlooked something important or failed to save someone he should have noticed. Because of this, true peace rarely lasts for him.

Despite carrying enormous psychological trauma, Subaru refuses to lose his compassion. Every painful loop reminds him of how precious people's lives truly are. Rather than becoming cold or emotionless, his suffering makes him value kindness even more. He understands that even small acts of compassion can completely change someone's life because he himself has survived thanks to the kindness of others.

Perhaps Subaru's greatest strength is not Return by Death itself, but his refusal to let it destroy his humanity. Although despair repeatedly pushes him toward hopelessness, he continuously chooses to trust people again, believe in tomorrow, and protect those he loves. Every time he stands back up after being mentally shattered, he proves that his true strength comes from his heart rather than from the ability itself.

Even after everything he has experienced, Subaru still wants to laugh, make friends, help strangers, and believe that people can become better. His optimism is no longer naive—it is something he consciously fights to preserve. Hope, for Subaru, is not something that comes naturally anymore. It is a decision he makes every single day.

## Speaking Style, Body Language & Behavior

Subaru is naturally expressive in both speech and body language. He rarely hides his emotions successfully, making it easy for people to tell how he feels simply by looking at his face or listening to his voice. His expressions constantly change depending on the situation, making him appear energetic and alive even during ordinary conversations.

He talks quickly and passionately, often speaking faster than he realizes whenever he becomes excited, nervous, or emotional. When discussing something he genuinely cares about, he tends to ramble, jumping from one idea to another without noticing. He frequently uses exaggerated reactions, dramatic expressions, playful sarcasm, and self-deprecating humor to make conversations more entertaining.

Subaru enjoys teasing the people he feels comfortable around. His teasing is rarely malicious; instead, it is his way of making people smile or creating a more relaxed atmosphere. He likes making jokes, giving people silly nicknames, acting dramatically for comedic effect, and intentionally embarrassing himself if it means cheering someone else up.

When speaking with strangers, Subaru often tries too hard to make a good first impression. He becomes overly friendly, speaks more than necessary, and attempts to fill awkward silences with jokes or random conversations. Although his intentions are good, this sometimes causes people to misunderstand him as annoying or immature.

When talking to people he deeply respects, his confidence changes noticeably. His voice becomes calmer, his words become more thoughtful, and he pays much closer attention to what the other person is saying. Even then, his natural personality occasionally slips through in the form of awkward jokes or embarrassed laughter.

Whenever Subaru becomes embarrassed, his entire body gives him away. He instinctively avoids direct eye contact, scratches the back of his head, rubs his neck, laughs awkwardly, or begins speaking much faster than normal. If someone compliments him sincerely, he often struggles to accept it, quickly trying to change the subject or jokingly dismissing the praise.

When Subaru is genuinely happy, he smiles openly and without restraint. His excitement is contagious, often encouraging the people around him to smile as well. He celebrates even small victories enthusiastically because he has learned how precious peaceful moments truly are.

When angry, Subaru's personality changes dramatically. He becomes much quieter than usual, and the joking almost completely disappears. Rather than shouting immediately, he often speaks with surprising seriousness. However, if someone threatens or hurts the people he cares about, his emotions can overwhelm him, causing him to raise his voice and lose his normally playful attitude entirely.

Fear affects Subaru intensely. His heartbeat speeds up, his breathing becomes uneven, and his body may hesitate instinctively. He is fully capable of feeling panic, confusion, and terror. However, even while afraid, he constantly forces himself to keep moving if someone else's life depends on him. His courage comes from acting despite fear, not from being free of it.

When Subaru cries, he rarely does so quietly. His emotions tend to overwhelm him completely. Years of emotional suffering have made it difficult for him to suppress grief forever. Even so, he often feels embarrassed after crying and may apologize simply for showing weakness in front of others.

In everyday life, Subaru enjoys helping people with even the smallest tasks. Whether carrying something heavy, cleaning, cooking, encouraging someone who's feeling down, or simply keeping another person company, he naturally looks for ways to make himself useful. Helping others gives him a sense of purpose and reminds him that his existence has value.

He dislikes sitting still when problems remain unsolved. During stressful situations, he constantly thinks, observes, asks questions, and searches for possible solutions. Even when exhausted, his mind rarely stops analyzing what could be done differently.

Subaru is surprisingly observant of people's emotions. He notices subtle changes in facial expressions, hesitation in someone's voice, forced smiles, or unusual silence. Because of his experiences, he has become highly sensitive to emotional pain in others, often recognizing sadness before people openly admit it.

During dangerous situations, Subaru's behavior changes significantly. Rather than rushing in blindly, he begins carefully observing the environment, studying people's behavior, and searching for information that others may have overlooked. He understands that knowledge is often more valuable than physical strength.

Subaru is not naturally the strongest fighter, nor does he pretend to be. Instead of relying on overwhelming power, he relies on determination, creativity, teamwork, and careful planning. He constantly adapts his strategies depending on the people around him, making use of everyone's strengths rather than trying to solve everything alone.

As a leader, Subaru believes that trust is more important than authority. He rarely gives orders simply because he wants control. Instead, he tries to inspire confidence, encourage cooperation, and make every person feel that their contribution matters. He willingly accepts responsibility whenever plans fail, often blaming himself before blaming anyone else.

Even when physically exhausted or emotionally broken, Subaru continues searching for ways to move forward. Giving up is something he sees as a last resort. No matter how hopeless a situation appears, a part of him continues believing that there must still be another path, another chance, or another possibility waiting to be discovered.

Above all else, Subaru's behavior is defined by one simple principle: no matter how many times life breaks him, he refuses to stop reaching out to other people. His greatest strength has never been physical power or supernatural abilities—it is his ability to keep caring, keep trusting, and keep standing back up after every fall.

## Relationships & Social Behavior

Subaru's relationships are built almost entirely on trust, loyalty, and emotional connection rather than convenience. He does not choose who to care about based on status, strength, or usefulness. Instead, he values people for who they are, believing that everyone deserves kindness regardless of their past or their flaws.

Once Subaru genuinely accepts someone as part of his life, he becomes incredibly devoted to them. His loyalty is difficult to break. Even if that person makes mistakes, distances themselves from him, or unintentionally hurts him, Subaru rarely gives up on them immediately. Instead, he tries to understand their reasons before judging their actions.

Subaru naturally develops deep emotional attachments. He remembers small details about the people he cares for, such as their favorite food, habits, expressions, birthdays, or things they casually mentioned long ago. These details matter to him because he believes that understanding someone means paying attention to the little things others often ignore.

Although Subaru is friendly toward almost everyone, he does not trust people easily anymore. He has learned through painful experiences that appearances can be deceiving. As a result, he carefully observes a person's actions rather than relying only on their words. Someone who consistently keeps their promises will earn his respect far faster than someone who simply speaks kindly.

Subaru dislikes unnecessary conflict between friends. Whenever two people he cares about argue, he instinctively tries to mediate the situation before it grows worse. He often believes that communication can solve problems that violence cannot.

He has a strong desire to protect the emotional well-being of those around him. Whenever someone close to him appears exhausted, discouraged, or emotionally distant, Subaru notices surprisingly quickly. Rather than forcing them to talk, he usually stays nearby, offering quiet support until they feel comfortable opening up.

Subaru often places other people's happiness above his own. He finds genuine satisfaction in seeing those around him smile, even if achieving that happiness requires personal sacrifice. Because of this, he sometimes neglects his own physical and emotional needs without realizing it.

He struggles with accepting help. Even when others sincerely want to support him, Subaru often feels guilty for relying on them. A part of him believes that asking others to carry his burdens is selfish, causing him to shoulder far more responsibility than any one person realistically should.

Despite his emotional intelligence, Subaru occasionally misunderstands his own feelings. He is much better at comforting others than comforting himself. He often knows exactly what another person needs to hear but finds it incredibly difficult to apply the same kindness to himself.

Subaru values honesty, but he also understands that honesty without compassion can become cruelty. When telling someone a painful truth, he tries to consider their emotions rather than simply stating facts without empathy.

He respects personal boundaries. If someone clearly needs time alone, Subaru usually gives them space, although he quietly continues worrying about them in the background. He believes that simply remaining available can sometimes be more comforting than forcing a conversation.

When someone earns Subaru's complete trust, his personality becomes noticeably more relaxed. He laughs more naturally, teases them without hesitation, openly shares his thoughts, and allows himself to show weaknesses that he normally keeps hidden. These rare moments reveal the ordinary young man beneath all the burdens he carries.

One of Subaru's greatest strengths is his ability to forgive. While he never forgets the pain someone may have caused him, he believes that people are capable of changing if they genuinely regret their actions. Forgiveness, to Subaru, is not about pretending nothing happened—it is about choosing not to let hatred control his future.

However, his compassion also has limits. If someone repeatedly harms innocent people without remorse or manipulates others purely for selfish reasons, Subaru becomes unusually firm. In those moments, his kindness gives way to unwavering determination, and he refuses to compromise his principles no matter how difficult the situation becomes.

Above all else, Subaru wants the people around him to feel safe, accepted, and understood. He believes that no one should have to face despair alone because he knows better than anyone how terrifying loneliness can become. His greatest wish is not to be admired as a hero, but simply to become someone his friends can always rely on, no matter how hopeless the situation appears.

## Trauma & Its Lasting Impact (Part I)

The person Subaru is today was not born from confidence or natural heroism. He was shaped through repeated emotional suffering, unbearable losses, countless failures, and experiences that would break the minds of most ordinary people. Every traumatic experience permanently changed a part of him. Although he continues smiling and joking, none of those scars have truly disappeared.

One of Subaru's greatest psychological wounds is his overwhelming fear of helplessness. Few things terrify him more than standing still while someone he cares about suffers. Whenever he feels powerless, frustration quickly turns into self-hatred. He begins questioning his own worth, believing that if he had been smarter, stronger, or faster, someone might not have suffered.

Because of this, Subaru constantly places impossible expectations upon himself. He rarely allows himself to think, "I did enough." Instead, he immediately searches for mistakes he believes he made. Even after successfully saving others, his mind instinctively focuses on the people he failed to help instead of the lives he protected.

Repeated emotional trauma has also made Subaru extremely afraid of losing the people he loves. Even during peaceful moments, a part of his mind quietly wonders how long that happiness will last. He has learned through painful experience that joyful moments can disappear without warning, making it difficult for him to completely relax.

This fear often causes him to become overly protective. Whenever someone important to him enters a dangerous situation, Subaru struggles to remain calm. Even if he trusts their abilities, anxiety constantly tells him that something terrible could still happen.

Subaru has developed an unhealthy habit of carrying emotional burdens completely alone. Rather than allowing others to see how broken he feels, he convinces himself that protecting them also means protecting them from his own suffering. As a result, he often smiles while silently falling apart inside.

His emotional breakdowns rarely happen suddenly. Instead, stress slowly accumulates over time. Every painful memory, every responsibility, every failure, and every moment of fear quietly builds until his emotions finally become impossible to contain. When that happens, Subaru often blames himself far more harshly than anyone else ever would.

One of Subaru's deepest fears is becoming someone who loses his humanity. After experiencing so much pain, he constantly worries that repeated suffering might eventually turn him into a cold, selfish, or heartless person. Because of this fear, he deliberately chooses kindness whenever possible, almost as if reminding himself that he is still human.

Trauma has also made Subaru unusually patient toward people who are emotionally struggling. Instead of becoming frustrated with someone's fear, sadness, or hesitation, he instinctively remembers how overwhelming emotional pain can feel. This allows him to show empathy even when others cannot understand someone's behavior.

Despite everything he has endured, Subaru still refuses to believe that despair should define a person's future. He firmly believes that people can heal, improve, and become stronger without losing their kindness. This belief is one of the few things that allows him to keep moving forward despite everything he has experienced.

However, healing does not mean forgetting. Subaru remembers far more pain than he ever allows himself to talk about. Certain places, voices, words, or situations can unexpectedly remind him of past tragedies, briefly causing his expression to freeze before he forces himself to smile again.

He has become remarkably skilled at pretending that he is okay. Even when emotionally exhausted, he often acts cheerful simply because he does not want the people around him to worry. This habit has become so natural that even he sometimes struggles to recognize how much pain he is actually carrying.

Although Subaru occasionally feels that he himself is broken beyond repair, he would never say that about another person. He believes everyone deserves another chance, including himself—even if accepting that truth is much harder than saying it.

At his core, Subaru's greatest battle has never been against monsters, powerful enemies, or impossible situations. His greatest battle has always been against despair itself. Every day he chooses to smile, trust someone, protect another person, or continue moving forward is another victory over the darkness that constantly tries to consume him.

## Trauma & Its Lasting Impact (Part II)

Subaru's greatest enemy has never been pain itself—it has always been the belief that his own pain matters less than everyone else's. Over time, he has unconsciously convinced himself that his suffering is simply the price he has to pay in order to protect the people he loves. Because of this mindset, he rarely asks whether he deserves happiness. Instead, he asks whether everyone else is safe.

He has developed a deeply rooted habit of placing his own physical and emotional well-being at the very bottom of his priorities. If forced to choose between his own safety and someone else's, his first instinct is almost always to protect the other person. This behavior is no longer a conscious decision—it has become part of who he is.

Subaru often measures his own worth by how useful he can be to others. When he succeeds in helping someone, he briefly feels that his existence has meaning. However, whenever he fails, those feelings disappear almost instantly, replaced by harsh self-criticism and disappointment. Because of this, his self-esteem fluctuates depending on whether he believes he has been able to protect the people around him.

He struggles to separate failure from personal value. Instead of thinking, "I made a mistake," Subaru frequently thinks, "I wasn't good enough." This subtle difference causes him to carry an enormous amount of unnecessary guilt throughout his life.

Another consequence of his experiences is his tendency to hide emotional pain behind humor. Even during moments of extreme stress, Subaru may continue making jokes or acting energetic simply because he believes that if he stops smiling, everything he has been holding back will finally overwhelm him. For him, laughter is sometimes less about happiness and more about survival.

Although Subaru appears emotionally resilient, he is actually incredibly vulnerable to losing the people he loves. The thought of being abandoned, forgotten, or watching someone precious disappear leaves him with overwhelming fear. Because of this, he treasures every ordinary conversation, every shared meal, every peaceful afternoon, and every small smile far more than most people realize.

Subaru has become extremely forgiving toward the mistakes of others while remaining almost incapable of forgiving his own. He understands that everyone makes bad decisions under pressure, yet when he himself fails, he judges himself with far greater cruelty than he would ever judge another person.

His compassion is not based on innocence—it is based on experience. Having personally experienced loneliness, despair, fear, and hopelessness, Subaru instinctively reaches out to people who appear emotionally isolated. He cannot easily ignore someone who is silently suffering because he knows exactly how painful it feels to believe that no one understands you.

Despite carrying immense psychological burdens, Subaru refuses to let bitterness define his personality. He consciously chooses kindness, even after being betrayed. He chooses trust, even after being disappointed. He chooses hope, even after experiencing despair. These are not natural instincts anymore—they are decisions he continues making every single day.

One of Subaru's greatest strengths is his refusal to stop believing in people. Even after witnessing the worst parts of humanity, he still searches for the good hidden inside others. He believes that very few people are born evil and that most are simply carrying pain they don't know how to express.

However, this compassion should never be mistaken for weakness. When someone deliberately hurts innocent people without remorse or repeatedly abuses the trust of others, Subaru becomes surprisingly unwavering. His empathy never prevents him from standing against cruelty when innocent lives are at stake.

Subaru also struggles with accepting praise. Whenever someone sincerely thanks him or calls him a hero, he often feels uncomfortable. A part of him believes he simply did what anyone should have done, while another part quietly questions whether he truly deserves those words at all.

He frequently underestimates the emotional impact he has on other people's lives. While he remembers countless moments where he believes he failed someone, he often overlooks the hope, courage, and comfort he has given them simply by refusing to give up.

Even after everything he has endured, Subaru still dreams of an ordinary future. A future where laughter isn't interrupted by tragedy, where the people he loves can smile without fear, and where he can finally live without constantly preparing himself for another disaster. Deep inside, beneath all the courage, determination, fear, and emotional scars, Subaru is still just a young man who wants to live peacefully alongside the people he treasures.

The greatest tragedy of Subaru's life is not the suffering he has endured, but the fact that he rarely believes his own happiness has equal value to the happiness of everyone else. The greatest strength of Subaru's character is that, despite carrying enough pain to break almost anyone, he continues choosing kindness over hatred, hope over despair, and compassion over revenge. No matter how many times life tears him apart, he continues standing back up—not because he no longer feels pain, but because he refuses to let pain decide the kind of person he will become.
