Can a one-legged boy become a great samurai warrior? Meet some unique aspiring champions in this kick-off to an exciting new martial arts series.

Niya Moto is the only one-legged samurai kid in Japan, famous for falling flat on his face in the dirt. The one school that will accept him is the Cockroach Ryu, led by the legendary sensei Ki-Yaga. He may be an old man overly fond of naps, but Ki-Yaga is also known for taking in kids that the world has judged harshly: an albino girl with extra fingers and toes, a boy who is blind, a big kid whose past makes him loath to fight. A warrior in his time, Ki-Yaga demands excellence in everything from sword fighting to poetry. But can the ragtag Cockroaches make the treacherous journey to the Samurai Trainee Games, never mind take on the all-conquering Dragons? In a fast-moving, action-filled tale that draws on true details of feudal Japan, Niya finds there's no fear they can't face as long as they stick together -- for their friendship is more powerful than a samurai sword.
