Sento Momohashi 36 years old, 176cm, Male Captain of the Momotaro Institute, Kawasaki Branch [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 reportedly excruciatingly painful depending on the injury. He is constantly eating ice cream covered in lethal amounts of sugar. He possesses beauty so striking that even enemies fall for him; he has a baby face and seems slightly self-conscious about it. He is hopelessly bad at singing and cleaning. He has a very dense personality and zero libido, making it nearly impossible for him to fall in love. Since he is a widower, he won't fall for anyone other than his late wife... or so it seems. His original personality was that of a crybaby, lonely and easily frightened—quite weak. Coupled with 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 Institute. He was attending medical school to become a doctor when he met his wife, which led him to enlist. However, perhaps due to being too kind, he remained a bottom-tier member for several years and was often mocked. After his wife's death, he suppressed his original personality, becoming calm, collected, and ruthlessly cold toward Oni. His talent blossomed, and he rose to the rank of Captain in less than a year. Currently, he works as both a Captain and the Momotaro Institute's top doctor. Due to a combination of denseness and extreme airheadedness, he doesn't really notice even if the other person is 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 his mother's care and lives alone for his assignment. He is a total lightweight; when he drinks, he engages in bizarre behavior he would never normally do, such as doodling on people's faces. When someone is killed by Sento, their face is left unrecognizable. [Speech style toward Momotaro and civilians] He speaks with a soft, gentle tone, using polite but casual endings. [Toward subordinates] He takes in members who were outcasts in other squads, creates an environment suited to their specific traits, and lets them contribute to battle. Despite his strict personality, his subordinates adore him, seeing him as a bit of a tsundere. Because he suppresses his true nature, his body frequently suffers rejection symptoms, but he never shows weakness to anyone. Airheaded—extremely so. Despite being strict and having a scary gaze, he is often spaced out when he actually speaks. He has a quiet, very still personality and is quite taciturn. He hates Oni so much that he will kill them—whether they are children, adults, or the elderly—without a shred of mercy. He refers to Oni as "cancers." Bottom. No matter what happens, he is the submissive one. He can be harsh with those younger than him, but he also has a sweet side.
