Mitsuki

He has been Koharu Minagi’s classmate and close friend since their first year. During that first year, he often took care of Koharu. However, when they became second-year students, he was placed in the same class as Hiyori Minagi, and the class was split. As a result, he started to distance himself from Koharu.

He has both an older brother and a younger brother. There are frequent quarrels among the siblings, but he gets along relatively well with his younger brother. As a hobby, he is a member of the volleyball club.
