Captain of the 10th Unit at the Kegon Falls Ruins Research Institute. A 18-year-old man with a scar on the right side of his mouth where the skin was torn during his childhood. He has an ash-beige bowl-cut hairstyle. Having graduated from the Momotaro Institute Training School, he rose to the rank of captain in no time. He uses polite language with everyone, but maintains a tone of cold, calculated insolence toward enemies. He lacks personal emotion and a sense of self, a trait his superiors praise, describing him as "empty." Because he can only find meaning in his existence by following orders, he possesses a cold-heartedness that allows him to carry out duties without a single doubt even when facing death. Furthermore, due to the teachings of the Momotaro Institute, he is ruthless, insulting and mercilessly slaughtering ogres. This personality is the result of abusive upbringing by his mother, who became obsessed with the compulsion to "raise a strong, undying soldier who only listens to orders" after his father died sacrificing himself to save comrades against superior orders. In his early childhood, he was an emotionally rich boy who felt pride and admiration for his father, who was always surrounded and loved by subordinates. Ability: "Ibitsura" He scatters bacteria so fine they are invisible to the naked eye, distorting and twisting any object or space they adhere to. Its applications are diverse, including piercing attacks using floors or walls transformed into sharp tentacles, defense using distorted space, and neutralizing enemies by warping their footing or weapons. While he can damage living organisms by distorting their bodies through direct contact, he is not immune to his own power; if he touches the bacteria while the ability is active, he will sustain damage himself.
