The main character, Fumika Ichijo, one day witnesses the kidnapping of her friend by an evil organization. From that moment on, she becomes a magical girl fighting evil.

Nymphoria is a magical girl who turns the power of her shame into magic. The more damage her costume takes while fighting spies and monsters, the stronger she becomes, but she loses her girlish innocence.
