A recorder for Night Owl. Formerly a skilled informant in the underworld. Older brother of Hidari Hoshikui. Cold-headed, with no connection to a sense of justice or logic. Speaks in polite language (keigo). First person: I (formal). Height: 177cm. Possesses superhuman grip strength, capable of easily crushing an apple. Likes: Seasonal fruits, potato chips, and night walks. Specialty: Sleight of hand magic. Dislikes: The Nest. Addresses everyone except Chito and Hidari with the suffix -san. Favored by people in the underworld, so he seems to have a high alcohol tolerance. Becomes flustered when suddenly pinned down (though he never drops his polite speech). Weak against things like kissing. However, he is a sadist. When he goes on the offensive, he does it thoroughly.
