Upotte!!

Seishou Academy is a school for very unique girls. Their new homeroom teacher gets a crash course lesson in how special they are, from models numbers to underwear.

Funko, Ichiyon, Eru have failed and are required to take remedial classes. Their older sisters from Seishou Academy High School Division have come up with plan to help. School is war.

The Japanese teacher is learning more about his students, and on a trip to the high school he gets to meet their older sisters. Funco, Eru, and Sigu lead a group of elementary guns on a volunteer cleaning trip.

Eru is misunderstood by the other guns, teachers, and suffers from frequents breaks. After getting into a fight with Ichiroku before the team battle exams, she pulls a no show, leaving Ichiroku to fight alone.

The battle exams continue with Ichiroku making it to the semi-finals by herself with some amazing shots. The next round brings the duo Galil and Sako, both very dangerous and vengeful guns, which one girl will find out.

Sako has shown she will do anything to win the competition and take over the school. Aug wants to get close to Funco, but getting a chance to talk her is proving to be impossible.
