The Amami family consists of Hasaku-kun, his older sister Mao and little sister Airi-chan. Their parents became the founders in founding the academy to foster love between students, but they died in an accident. Their birth aunt Mei took over the academy and forced older sister Mao to step down as founder. Her plan was to turn the academy into an elite Mecha-Con-type institution where girls must learn the craft of love and the ability to sell themselves to rich and wealthy men. In short, a sort of academy for perfect brides... Unfortunately for Aunt May, all of the academy's students must sign a charter, and since there are male students here, this is not possible. Mei forces the girls under her control to bully the boys and force them to leave the academy. Of course, in the end, almost all the guys left the academy, leaving only our protagonist Hassaku-kun. Auntie Mei tried her best to make him leave the academy, but she failed, because he turned out to be a really tough guy. Sex and humiliation were the only things the poor and exhausted aunt had left in store...
