Meet Mon, a violent killer faithful only to his own eruptive desires, and his timid companion Toshi, a demolition-devil with a fanatical thirst for destruction. Their killing-spree across Japan is destined to intersect the path of the enormous "Higumadon", a mysterious beast on a Godzilla-like rampage from Hokkaido to Tokyo.

A young, unemployed, seemingly unmotivated young man is moving through his life. As a teenager, he and some of his friends formed a "Boyz 4 Men" club, which was based on a hatred of sex and women. As arguably the most opinionated member, his view of sexuality as an adult is far from normal. After a highly sexual encounter in a park at night, he has decided to attempt to draw perverted fetish manga. This brings him once again to the presence of a woman from the park, Sawada Kazumi. She's a manga editor and single mother with a perverted and intense personality of her own. What will happen when their worlds collide?
