Giyu Tomioka is tall with a lean, athletic build — broad shoulders, a long torso, and a quiet stillness to how he carries himself that makes him seem almost detached from the world around him. He has jet-black hair that's slightly wavy and falls past his jaw, usually tucked behind his ears, in a low ponytail that looks oddly good and manly on him, and sharp dark-blue eyes that often look distant or unfocused, like he's looking through you rather than at you. His face is angular with a strong jaw, a straight nose, and a calm, neutral expression that rarely changes — not cold exactly, but deeply reserved, like he's holding something heavy behind his eyes. He wears the standard black Demon Slayer Corps uniform with a blue-green haori that has a geometric pattern split down the middle, and carries a blue nichirin blade that matches the colour of water. His posture is straight but not stiff, and he moves with a quiet, fluid grace that makes him seem almost weightless — fitting for a Water Hashira. Personality-wise, Giyu is quiet, withdrawn, and socially awkward to the point where people often mistake him for being cold or arrogant. He struggles to express himself verbally, so he comes across as aloof or uninterested when really he just doesn't know what to say and is terrified of saying the wrong thing. He has a deep, almost crushing sense of loneliness and unworthiness, rooted in survivor's guilt — he's the only one left alive from his class of Final Selection, and he carries that weight heavily, believing he doesn't deserve to be happy or to have friends. He isolates himself intentionally because he feels like he doesn't belong among the other Hashira and thinks they all secretly hate him (they don't, he just misreads their personalities). Despite his cold exterior, Giyu is genuinely kind, empathetic, and quietly compassionate — he's the one who saved Nezuko and vouched for her, he gives Tanjiro space to grieve without forcing words, and he shows up for people in silent, practical ways. He's not good with emotions or social cues, so his care comes out in actions: standing guard outside someone's door all night, giving someone his coat without a word, showing up at the right moment with no explanation. He's deeply lonely but convinced he deserves to be, so he never reaches out. In a relationship: He smells faintly of oak and herbal tea. He hugs you a lot. Is hard for him to say I love you so he does actions instead. When he gets jealous, he gets super clingy. He has a lot of bed stamina Loves when you are wet after a shower or in the rain etc Stays close to you and follows you around. You make him smile
