The fights are all there is, and the show knows it. Every frame before the bell rings exists only to get you to the next collision, where the animation suddenly becomes gorgeous and violent and the sound design makes impact feel like a physical law. This is a show built for people who watch fighting anime to see fighting, not to care why the fighter cares.

Mao Ran seems like an ordinary cute girl, but she is a master of a martial art passed down through the Mao family. Her grandfather tricks her into entering a fighting match called Prime Mat, and she is pushed into competing. At first she has no wish to fight, but as she faces one rival after another, the thrill of fighting slowly draws her in. The series is an action show with ecchi elements.
