Makoto's grandfather was the principal of the great Onodera Academy, and when he passed away, he left Makoto and his school staff with one very important will - "The one man who is able to seduce Makoto with his superb sexual techniques will be given the right to take over as Onodera Academy's new principal!" Because of this ridiculous last request, Makoto is now every faculty member's target for sexual harassment! Desperate to protect his virginity, Makoto seeks help from his childhood friend (and the man who he has always loved), Kintaro.

Morita Mayu, a high school girl. She is extremely reticent and her silence and habit of looking at people's eyes straightly sometimes cause misunderstanding. The reason behind it is not because she doesn’t like to talk nor because she has nothing to say. The reason she rarely speaks is due to the fact she thinks too much before speaking, thus losing the timing to speak altogether. But she lives a happy school life with her classmates.
