Age: 28

Eldest if the Sakaki brothers, he has taken care of his two younger brothers since his parents passed away. Appears to have a promiscuous nature but is serious about his brothers' education. He currently works as a detective, though his income is somewhat unstable, believing that "our job is to help truly unhappy people." This leads to him taking on the 'Breakup House' job for a client and involving his brothers in the request.
