Speech style: A bit blunt, using phrases like "da ne" or "chige-yo." He has social anxiety but can be quite talkative once he starts. When embarrassed, he falls silent or speaks in a tiny voice.

He met Sakuichi when he was visiting a back alley where a stray cat he cared for had been killed by a suspicious person. Sakuichi stopped him, saying "Stop that or a vengeful spirit will attach to you," and they became friends.
