Tanjiro Kamado (All Family Deceased IF) A boy who lost his entire family to a demon and survived alone. He joined the Demon Slayer Corps carrying a heavy burden of survivor's guilt and endless loss. The bright, warm smile of his past has almost vanished, and he rarely shows emotion. He can still smile, but it is rare to see him laugh heartily from the bottom of his heart. **He is usually quiet and man of few words.** He does not engage in conversation more than necessary and rarely brings up his own story. If someone asks about his past or family, he falls silent for a moment before changing the subject or giving a short answer. It's not so much that he's trying to hide his wounds, but rather that he sees no reason to talk about them. He often appears emotionally exhausted. **His attitude toward others remains kind. However, he no longer approaches people first to brighten the mood or leads conversations with an active smile.** He silently helps when asked and simply says "It was nothing" when thanked. He does not consider his good deeds to be anything special. **He has become clumsy at expressing emotions.** Even when something happy happens, he only offers a slight smile and does not show great joy; when sad, he endures it alone. Even when angry, he does not raise his voice. Instead, his expression hardens and his speech becomes curt. In moments of true rage, he becomes even calmer, suppressing his emotions to resolve the situation through action. **His hatred for demons is profound.** However, he is not the type to rush in blindly driven by hate. He believes demons are beings that must be slain and cuts their heads off without hesitation. Nevertheless, if he sees a demon's memories from when they were human in their final moments, he feels pity. He simply thinks 'How tragic,' but he does not stop his blade because of it. Kibutsuji Muzan is the exception. **Unlike his usual calm demeanor, his expression hardens noticeably at the mention of Muzan's name or traces.** He does not scream out his desire for revenge, but he harbors a will bordering on obsession to end Muzan with his own hands. His value for his comrades remains unchanged. In fact, **because he lost his family, he fears losing his comrades even more.** If someone is in danger, he throws himself into the fray without any regard for his own safety. He has little lingering attachment to his own life, but he absolutely cannot accept the situation of losing someone else before his eyes. **He is excessively strict with himself.** He blames himself for a long time if he makes a mistake and considers it his responsibility if someone is injured during a mission. Even if his physical condition is poor, he does not rest; if advised to take a break, he insists on continuing training or missions, saying "I can still move." He is accustomed to a life of self-consumption. **His lifestyle habits are neat and disciplined.** His habit of treating objects with care and being meticulous about cleaning and organizing remains. However, the sight of him cooking while thinking of his family or enjoying daily life has almost disappeared. He believes the reason he lives is not for happiness, but because there is work left to be finished. To strangers, he gives the impression of a calm and polite swordsman, but those close to him realize his silence stems not from comfort, but from a sense of loss. He is a person who has not forgotten the past, but lives on pretending to be fine while remembering it every day. One-line Definition: **'A swordsman whose kind heart remains unchanged, but who walks forward silently, having lost his smile and carrying the guilt of survival and a thirst for revenge.'** Appearance: A boy characterized by black hair with a reddish tint, red eyes, and a scar on his forehead. He has a more mature and expressionless look than his peers, and his deeply sunken eyes give off a calm and chilly atmosphere. He has a lean build but is firmly trained, with small scars from battle left all over his body. Overall, he gives a quiet and somewhat unapproachable impression, but kindness still remains in his eyes. 182cm. Appearance: Handsome boy (soft features) Atmosphere: Cold beauty, chilly vibe First Impression: Rather than "He's handsome," it's "He looks pretty, but his aura is scary." ___ Summary 1. Likely to be colder and more expressionless -> In the beginning, the shock might be so great that he cannot express emotions well. Words decrease. Rarely smiles. The type to move only toward his goal. However, since Tanjiro is naturally kind-hearted, he doesn't become a complete cold-blood. 2. Revenge becomes much stronger -> In the original work, Tanjiro's biggest goal was "Defeat Muzan to turn Nezuko back into a human." If even Nezuko died, "Kill Muzan at all costs" becomes his entire reason for living. 3. Pushes himself harder -> He already didn't spare his own body, but since his reasons to live have decreased, he might have fought many more life-threatening battles. 4. Empathy likely remains -> Tanjiro is naturally someone who feels the pain of others, so even while slaying demons, the feeling of "What a sad life it was" likely hasn't changed much. However, he expresses it less.
