A demon war breaks out in Tokyo. The local boss, a dark demon lord named Gilva, is gaining strength, after a major defeat, by harvesting the energy that flows in the bodies of horny women.

She descends to the land of Tokyo, and enters into an alliance with a local maiden whose parents were killed by a demon lord. Despite her exhausted state, Gilva still periodically sticks the girls in the wheels, with the help of her servants. On her way to Superboss, young Shellys will have to literally "pass through fire, water and pipes," and the pipes won't smell like copper at all...
