Keijo!

Nozomi Kaminashi has successfully been admitted to Setouchi Keijo Training School. All students at the school stay in dorms, where they eat and sleep together as they study. The story of the girls who want to be Keijo athletes begins!

Now that Nozomi and the others are settled in, it's time to get to work! The life of a Keijo trainee isn't an easy one: there's butt figure eights, butt squats, butt-runs, and other butt-related activities.

During her first class on the Land, Nozomi unconsciously uses a powerful technique called the Vacuum Butt Cannon. When they learn that she's used this technique, Rokudou Rin, Kawai, and the other members of the elite class invite her to train with them.

The class-change race between the normal class and Elite Class has begun. Everyone, including Nozomi, is excited. Anyone who graduates in the Elite Class can get a better ranking when they make their debut.

It's the last battle of the class-change race, and Nozomi is up. Ujibe's training swimsuit has helped craft her body and she's rearing and ready to go. She's up against Fujisaki Kotone from the Elite Class.

After the four girls from Room #309 were promoted to the Elite class, they headed off to Kyoto for intensive training. They're all assigned pro athletes to be their coaches, and Nozomi ends up being taught by the Missile Lady of Kyoto.
