A national-level wrestler named Ogata experiences a strange curse that causes him to alternate between his usual muscular form and a more youthful, boyish appearance whenever he suffers a nosebleed. His life becomes complicated as he faces challenges from a group of individuals who are intensely drawn to his younger look, as well as members of the student council who have a strong preference for muscular builds.
