Plot
Teppei lives in the forest with his father, who is a treasure hunter. Teppei and his father are visited by an older boy named Nakajo from a school outside the forest, who demands that Teppei comes with him. After a brief skirmish, Nakajo kills one of Teppei's pet wild animals, enraging the younger boy. This results in Teppei blowing up part of the forest with dynamite and him and his father being arrested.
Soon, Teppei's uncle finds him and brings him and his father to the city to reunite with his family. They are invited to live there from now on. Teppei joins a school, where we discover that he is illiterate. He sleeps through the majority of his lessons. After being forced to join a club, he settles on the Kendo club where he impresses the members by running 50 laps around the school. He is allowed to join and soon begins to demand radical changes to the system. Eventually, he takes charge of the younger half of the club. 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.
Soon after this event, the younger half resign out of fear, leaving Teppei to compete alongside the older half against the other school, but after a close competition with the other school - Nakajo's school - they end up losing.
