|Birthday: August 8th|
Hachiman is anti-social in his behaviour, choosing to not engage in conversations unless he finds it necessary. While he will claim to have no friends he gets along well with his younger sister Komachi. After joining the Volunteers Club he begins interracting with a larger group of people and thus making his first friends.
Unlike Yukinoshita Yukino and Yuigahama Yui, Hachiman did not join the Volunteers Club by choice, but was forced into the club by his homeroom teacher Hiratsuka Shizuka in a attempt to change his personality to one more accepting of teengage life and the other students of the school.
