Takeru's first day at the Tenbi Academy is full of fights and panties. After accidentally kissing a second-year girl, she challenges him to a duel in front of the entire student body. Without a Maken or Element, how is he supposed to protect himself?

Takeru decides to join the Security Committee! To welcome its new members, the Committee takes a trip to the hot springs. Things are going well until a bear shows up, giving the girls of the Tenbi Academy a chance to show off their special powers.

It's time for the clubs at Tenbi to negotiate their annual budgets! Takeru and Uru try to work together to help the Security Committee, but their work is interrupted by an assailant who claims to be responsible for the random acts of violence on campus.

A group of beautiful, powerful transfer students arrive at Tenbi in order to root out a mysterious secret society. But before they can get to work, they'll have to prove their strength against the girls of Makenki in an epic volleyball showdown.

The boys of Tenbi Academy petition the faculty for co-ed swim classes (for the sake of gender equality, of course). Naturally, the girls protest. There's only one way to solve this dilemma: a boys-versus-girls water fight full of swimsuits and nosebleeds!

Takeru gets a Maken! The secret history of Makenki! A dangerous new threat! But most important, the girls of the Security Committee don their skimpiest outfits and get jobs at the local maid cafe in order to pay for their bikini-filled summer camp.
