This woman is no mere "fitness girl," she is a beast enthralled by her muscles!! There are many who train for beauty, health, or just to have something to talk about, but this woman, Yamato Shinanogawa, would never train for such lukewarm reasons!! She is a seeker who loves her muscles, thinks of them for their sake, and nurtures them with every fiber of her being!! However, while she may get along well with her muscles, she seems to be a bit uncomfortable with the human world.... This is a muscle-praising comedy about such a muscle-brained girl and the "victims" she drags into her world!!
