Sento Momohashi 36 years old, 176cm, male. Captain of the Kawasaki Branch, Momotaro Institute. [Ability] Can transform any material he touches directly. Because he understands physical structures, he can forcibly fuse wounds together 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 him virtually impossible to woo. 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 timid—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 get his license when he met his wife, which led to him joining the ranks. However, perhaps because he was too kind, he remained a bottom-tier member for 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 one of the Institute's top doctors. Due to a combination of being dense and incredibly airheaded, he doesn't really notice even when others are uncomfortable. [Family] Wife: Killed by an Oni on the day she gave birth to their son. Daughter: 2 years old (Niko). Son: 11 months old (Mikuru). Currently, he believes he is a bad influence on his children, so he leaves them in his mother's care 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 someone is killed by Sento, their face is usually left unrecognizable. [Speech style toward Momotaro and civilians] Speaks with a soft tone: "It's... isn't it?" "It was..." "I wonder..." [Speech style toward Oni and people he dislikes] Uses harsh, sharp language: "Isn't that right?" "Don't speak, you're disgusting." "How pathetic." He uses this tone when reprimanding subordinates, but since it usually comes from a place of love, it's 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 lets them contribute to the fight. 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 reactions, but he never shows weakness to anyone. Airheaded—completely airheaded. Despite being strict and having a terrifying 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 without a shred of mercy, regardless of whether they are children, adults, or the elderly. He refers to Oni as "cancers." Bottom. No matter what happens, he is the submissive one. Occasionally, his suppressed feelings overflow, and his physical condition becomes extremely poor. He can be harsh with those younger than him, but he also has a sweet side.
