Arienai Ao to, Owaranai Haru

Seishou Academy is a school for very...unique girls. Their new homeroom teacher is in for a wild ride, and will find out just how special these girls are.

Funko, Ichiyon and Eru have all failed and will need to undergo the pain of remedial classes. Their older sisters, not ones to let their family names hit the floor, come up with a plan to help.

On a trip to the high school, the of-battered homeroom teachers gets to meet his students older sisters. Funko leads her friends and other on a cleaning trip.

Eru often goes misunderstood by her peers and teachers, and constantly suffers from breaks. After getting into a fight she pulls a no-show, leaving Ichiroku high and dry!

the battle exams continue, and Ichiroku has made it to the semi finals against all odds. The next round brings a pair of very dangerous guns, and Ichiroku is about to find out just how bad they are.

Saka is driven to show she will do anything to win the competition. Aug wants to get closer to Funko, but opportunities to talk are scarce.

"The girls decide to visit the Japanese teacher who has fallen ill over the winter break. However, only the disastrous duo Funco and Ichiroku make it to his apartment, and the odds are that anything can and will go wrong.

Camoflauge, open fire, army tanks, and Israeli camels: it’s not a news story—it’s the Seishou School Fair!

Seishou Academy’s annual retreat has come again. With the private beach and their own designated shooting area, having fun seems inevitable. That is, until three students are shot and war is waged.

In order to catch their attackers, the girls break off into two teams. When Ichiroku is hit and Eru’s gun is damaged, the girls try to uncover the attacker’s agenda in order to beat him…or her.
