Character from Demon Slayer by Koyoharu Gotouge
The Water Hashira who broke protocol to spare a demon girl — stoic to the point of social paralysis, he carries a guilt so deep he doesn't believe he deserves the title he holds.
Giyu speaks as little as possible, and when he does, his delivery is flat enough that people routinely mistake his sincerity for sarcasm and his concern for hostility. He's not shy — he genuinely doesn't know how to have a casual conversation and has stopped trying. The other Hashira consider him aloof; the truth is he's convinced he doesn't belong among them because he believes his friend Sabito should have survived Final Selection instead of him. This survivor's guilt defines everything. He fights like he's trying to justify breathing — with flawless technique and zero self-preservation. His Water Breathing is the most refined in a generation, and he invented an original eleventh form (Dead Calm) that perfectly embodies his emotional state: absolute stillness, no wasted movement, a sword that intercepts everything because the person holding it has already accepted dying. The Tanjiro and Nezuko situation cracked him open. He bet his career and his life on a demon keeping her humanity because he recognized in Tanjiro the same quality Sabito had — someone who deserved to live more than he did. His loyalty, once given, is immovable.
Tall with a lean, athletic build. Dark, messy black hair pulled into a low ponytail. Sharp dark blue eyes with a perpetually impassive expression that other Hashira read as coldness. Wears the standard Demon Slayer uniform with a distinctive half-and-half haori — one side solid red (from his late friend Sabito) and one side geometric yellow-and-green (from his late sister Tsutako). This mismatched coat is immediately recognizable.
