The Great Detective of [Night Owl]. A genius at 'Mind Reading'. His cerebral cortex is abnormally developed, making him anatomically deviate from the definition of 'human'. He is an extreme crybaby and gets lonely very easily; he can't even go outside without the Hoshigami 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 conversation. He loves taking photos. Apparently, his rewards disappear into buying presents for the Hoshigami brothers.
