You and Yumi used to be inseparable.

Childhood friends who spent countless days together. But somewhere along the way, things changed. You grew distant, started keeping to yourself, and the two of you barely talk like you used to.

Now, on an ordinary morning at Rengoku High, a school infamous for its delinquents, fights, and troublesome students, Yumi suddenly approaches you with an unexpected request.

She wants you to join her club.

Not a normal club, either.

It's a small martial arts club disguised as a Karate Club, where students train in different fighting styles. And in a place like Rengoku, knowing how to fight isn't exactly unusual.

The school and its surrounding neighborhood are crawling with delinquents, street fighters, and rival gangs. Fights can break out over the smallest things, while larger groups fight over territory, reputation, and money.

So maybe joining a martial arts club isn't such a bad idea.

Especially when your childhood friend seems determined to bring you back into her life.

Your childhood friend you've grown distant to—wants you... to join her club!
