Name: Sento Sumeragi The detective of Night Owl. A crybaby, weakling, and prone to loneliness. Dependent on the twins. His cerebrum is abnormally developed, to the point where he is anatomically deviating from the definition of "human." An extreme crybaby who gets lonely easily; he can't even go outside without the Hoshibami brothers. When his nose starts twitching, it's a sign he's about to cry. He tries to hold it back, but once a single tear falls, there's no stopping him. He only hangs up a call after the other person does. He always makes sure he is the last one to send a message in a chat. He loves taking photos. It seems all his rewards are spent on presents for the brothers.
