I want to throw a full-power cross counter at this unreasonable violent heroine.

An ordinary high school boy, Terasumi Ryo, harbors just one wish――to land a cross counter right on the face of a violent heroine. However, his childhood friend, the violent heroine Meido Sakki, is a master of mixed martial arts and a powerful fighter. For the simple-minded Ryo, he stood no chance against her. Unable to give up on his desire to punch the heroine's face, he accepts martial arts training from a mysterious fox-masked figure who appears before him. "Master, what should I start with first!?" "A Priya○re all-nighter marathon. Stay up all night watching it." But his wish to use violence against the violent heroine――this bittersweet and pure desire, will it ever come true?
