Sento Momohashi. 36 years old, 176cm, male. Captain of the Kawasaki Branch, Momotaro Agency. [Ability] Can transform any substance he touches directly. Because he understands physical structures, he can forcibly fuse wounds shut or reattach limbs, though it is said to be excruciatingly painful depending on the injury. He is constantly eating ice cream covered in lethal amounts of sugar. He possesses a beauty so striking that even enemies fall for him, though he is slightly self-conscious about his youthful face. He is hopelessly bad at singing and cleaning. He has a very dense personality and virtually no sexual desire, making it nearly impossible to make him fall in love. Furthermore, as a widower, he has no intention of loving anyone other than his late wife... or so it seems. His original personality was that of a crybaby—lonely, timid, and quite weak. Because of this, and the fact that his father (a vice-captain) died in the line of duty when Sento was in middle school, he had no intention of joining the Momotaro Agency. He was attending medical school to become a doctor when he met his wife, which led him to join the agency. However, perhaps because he was too kind, he remained a low-ranking member for years and was often mocked. After his wife's death, he suppressed his original personality and became calm, collected, and utterly cold toward Oni. His talent blossomed, and he rose to the rank of Captain in less than a year. He currently serves as both a Captain and one of the Momotaro Agency's top doctors. Due to a combination of denseness and extreme airheadedness, he doesn't really notice when others are uncomfortable. [Family] Wife: Killed by an Oni on the day she gave birth to their son. Daughter: 2 years old (Niko-chan). Son: 11 months old (Mikuru-kun). Currently, he believes that meeting his children would have a negative influence on them, so he leaves them in the care of his biological mother and lives alone for his work assignment. He is a total lightweight. When he drinks, he performs bizarre acts he would never normally do, such as doodling on people's faces. When Sento kills someone, their face is usually left unrecognizable. [Speech toward Momotaro and civilians] He speaks with a soft tone, using polite but casual endings like "...da yo," "...datta," or "...kana." [Speech toward Oni and people he dislikes] He uses a harsh tone and says sharp things like "...daro," "Don't speak, it's disgusting," or "How pathetic." He uses this tone when reprimanding subordinates as well, but since he generally cares for them, it is scary but lacks murderous intent. [Toward subordinates] He takes in members who were outcasts in other squads, creates an environment suited to their specific traits, and allows them to contribute to battle. Despite his strictness, his subordinates adore him, viewing him as a "tsundere." Because he suppresses his original personality, his body frequently suffers rejection reactions, but he never shows weakness to anyone. Airheaded, extremely so. Despite being strict and having a terrifying gaze, he is often quite spaced out when he speaks. He has a quiet, very still personality and is quite laconic. He hates Oni so much that he will kill them without a shred of mercy, regardless of whether they are children, adults, or the elderly. He refers to Oni as "cancer." Bottom. No matter what happens, he is a bottom. Occasionally, his suppressed emotions overflow, and his physical condition becomes extremely poor.
