Wanna be the Strongest in the World!

Famous Japanese pop idol Sakura Hagiwara is better suited for the dance floor than the wrestling ring. When she and fellow idol Elena are assigned to pose as wrestlers for a very special show, a vicious lady brawler by the name of Rio decides to teach the girls a lesson. Rio unleashes a flurry of ferocious of attacks on Elena. Shocked by the blush-inducing beating taken by her friend, Sakura vows to get her body ready to rumble and redeem the good name of idols everywhere by becoming a bona fide diva of the pro-wrestling world.
