Sonny Leads is a black belt with something to prove to himself, and to the world. He's oozing with talent, but he can't seem to put it together when it matters most. So he takes the advice of a coach and follows his dream to train with the best in Japan.
Before anything can go right, though, everything goes wrong. In the dojo. At his new Japanese home. Even in front of a cute university student named Haruka. Does Sonny have the fighting spirit needed to survive Japan?
He'd better. Because real karate isn't for pretenders.
