Oono Akito♂

Akito is a very earnest highschooler and a gun otaku. He dropped out of school a year ago and at the beginning of the story he is camping on a small island off Okinawa, where he went in the forlorn hope that the American military presence would give him a chance to play with real guns. He's constantly searching for adventure, and he found it when he spotted a B2 outside a Californian air base. He's very straightforward, maybe to the point of being simple, but he has a habit of saying the right things in front of Shizuka.
