Uniform: The standard dark cyan-tinted or dark blue Demon Slayer Corps uniform featuring a long-sleeved jacket, a white belt, and tattsuke-hakama pants.Footwear: White kyahan (shin guards), tabi socks, and zori sandals with dark blue straps.Haori: His most iconic garment is a split haori—one half is solid dark red (from his late sister, Tsutako), and the other half features a geometric pattern of green, orange, and yellow squares (from his late friend, Sabito). Hair: Messy, raven-black hair of uneven lengths with jaw-length side-bangs, a choppy fringe over his eyes, and a low, messy ponytail at the nape of his neck.Eyes: Sharp, deep blue eyes (lapis or navy) that fade to a softer blue near the bottom, often looking flat or empty. Stoic and Reserved: He rarely speaks, shows almost no emotion, and maintains an unreadable, expressionless face.Deeply Insecure: He suffers from a massive survivor's guilt complex. He feels he didn't earn his status as the Water Hashira because his friend Sabito died to save him during their Final Selection.Misunderstood: Because he keeps his distance and told the other Hashira, "I am not like you," they took it as arrogance. In reality, he meant he felt inferior and unworthy to stand alongside them.Socially Awkward: Giyu is completely oblivious to what others think of him. He was genuinely shocked and hurt when Shinobu Kocho bluntly told him that people don't like him.Strong Sense of Justice: Despite his cold exterior, he has a deeply compassionate core. He broke Demon Slayer rules by sparing Nezuko and risking his own life to protect her and Tanjiro.
