Young at heart Akiyama is a manager at his company and has lots on his mind working at a manufacturer of washroom facilities. Naturally he relieves his day-to-day pressures and satisfies his fantasies by checking out the women he meets on his way. On occasion his fantasies combine the women (plural) that he comes across. Can he act on them?

Kondo Isami, a third-year high school student, has good grades but he is forced to decide which path to take because of his family’s financial situation. One day, he learns about the government-affiliated Defence Academy where students are not only exempt from admission fees and school fees, but are given an allowance every month. He wishes to go to this academy. After graduating from high school, Kondo enters the Defence Academy and meets Matsuhira Yosuke, Okita Soji, Harada Tadashi and Takei Tomoaki who become friends. He takes the first step to a new life, but when the entrance ceremony ends, the attitudes of the senior students including Sakaki Ryuya and Nishiwaki Takashi change drastically and strict coaching begins.
