When nude pictures of girls turn up on the school's noticeboard, everyone suspects the class outcast, Kenji. Only one girl, Atsuko, defends Kenji. He tells her if she REALLY wants to support him, she'll let him fuck her. And that shit actually works.
Her name is Erin. Together with the sword spirit Nighthawk, he is traveling the world to regain the magical power that was stolen. Erin and Hawk came to the Western-style building in the forest. Erin squeezes the spirits from the men in the maids' orgy.
