After possessing superpowers, Crystal's biggest dream became to protect the earth and become a superhero who would scare the evil forces. In order to realize this dream, in addition to going to school, eating and sleeping, Crystal also has an additional daily task - to fight against evil forces.

What's distressing is that she has a new competitor recently, and she can't even catch the thief! But it doesn't matter, the thief is gone, and there are other criminals, such as the professor who attempts to transform humans and turn into some kind of animal, the doctor who experiments to fuse himself with tentacles, and the terrifying demon hidden in the doll. Wait, what the hell is that last one? Even ghosts are under the control of superheroes? Purpose: The greater the ability, the greater the responsibility
