Synopsis

A new teacher shows up to Seishou Academy only to realize he's completely lost. He tries asking around at a summer festival and stumbles across a girl with incredible marksmanship at a shooting range. When he compliments her skills, she casually tells him she's not a student—she's an assault rifle named FNC, and she goes to Seishou Academy. Yeah, she's literally a gun. The next day at school, he watches students who are also guns practice with M16s, and it finally hits him: this is not a normal school. Now he's got to figure out what his job even is at a place like this. Also includes the 4-koma spin-off Upotte!! Nano.
