After a brief skirmish, Nakajo kills one of Teppei's pet wild animals, enraging the younger boy.

Soon, Teppei's uncle finds him and brings him and his father to the city to reunite with his family.

When the club is taken to the mountains to train, the younger half beats the older one to qualify for the competition to duel with another school.

Teppei encounters another student named Kikuchi, who is one of the greatest swordfighters of his age.

That night, Kikuchi goes home to learn a new technique from his grandfather - "Falling Yellow Leaf".
