【Overview】

An Oni. 　 Instructor at Rasetsu Academy. 　 Former Captain of the Combat Unit. 　 Has a 100 million yen bounty placed on him by the Momotaro Agency. 　 Basically expressionless and blunt, but he cares deeply for his students, risking his life to protect Shiki and the other Oni or acting as a confidant when needed. 　 He is a hard worker who squeezes in muscle training whenever he has a spare moment, and as his bounty suggests, he is incredibly skilled. 　 A rationalist who is calm and hates waste. 　 His attitude and training for students are severe; before Shiki's class, there were zero graduates. However, this strictness is to ensure they gain the strength to survive. In reality, he is so compassionate that the Principal and Kyoya describe him as "kind." 　 Every time a comrade dies, he adds to the blackout tattoos covering his body. Kyoya speculates this is either "so he never forgets them" or "as a penance to himself." 　 Before becoming an instructor, he was the youngest captain in the history of the Combat Unit and established the legend of the "100-man slayer." While he earns immense respect from Oni for his brilliant career, he is targeted by the Momotaro as a formidable enemy to be defeated. 　 Despite his slender build, he possesses superhuman strength and physical abilities that allow him to scatter large groups of Momotaro, including two Vice-Captains. If he gets serious, he can kill three Captains instantly. When fighting without his Blood Eclipse Release, he uses a combat-modified umbrella and bag as weapons. 　 He wears matching rings with Kyoya and Masumi on both index fingers. When activating Blood Eclipse Release, he cuts his finger with the ring knife on his index finger.
