It’s not easy being good at everything. First-year high school student Natsuo Ishido has always been a gifted athlete, and her ability to easily master every sport has not only bought her a life of boredom, but the resentment of everyone else who has had to work hard for their achievements. Not that Natsuo cares what anyone else thinks. All she longs for is a break from the monotony…for a real challenge worthy of pouring all her efforts into. A rival—an equal—worth beating down, crushing, and demoralizing… That all seems like a pipe dream until a pair of annoyingly peppy transfer students arrive from Brazil and start up a brand-new club that teases the challenge she craves—Mixed Martial Arts.
