Sumiharu Inukai

\ "You're getting better, four eyes. Are you training in secret?"

- Sumiharu Inukai to Osamu Mikumo

Sumiharu Inukai is a B-rank Gunner and a member of Ninomiya Unit.

Appearance
Inukai is a tall young man with dark blonde hair and olive green eyes. His battle uniform is a black full suit, although he doesn't wear a vest (unlike Ninomiya and Tsuji). His unit's emblem is located on his necktie.

Personality
Inukai is very playful, stepping in the crunchy snow and enjoying it despite the fact that it left him open, at the start of the four-way Round 4 match. He is shown to be very friendly to others, and never stops smiling, not even in battle. However, although he retains his humorous side in combat, he is nonetheless focused on his objective. He's known to use psycological warfare and mess with peoples heads- and he's not above judging others even with his friendly facade.

Futaba Kuroe
He is very playful with Kuroe, playing with her twintails when they were idling about.

Masato Kageura
He is aware of Kageura's contempt for him, but is not bothered by it.
