This woman is no ordinary gym girl; she is a beast possessed by muscle!! There are those who work out for beauty, health, or just to have something to talk about, but this woman, Yamato Shinanogawa, absolutely does not train for such half-hearted reasons!! She is a true seeker of the way who single-mindedly loves muscle, constantly obsesses over muscle for the sake of muscle, and cultivates it!!
However, while she gets along great with muscles, it seems she struggles just a little bit with the human world... This is a muscle-worshipping comedy about a total meathead girl and the poor victims who get dragged into her antics!!
