Ucchare Goshogawara  

Utchare Goshogawara, うっちゃれ五所瓦

At Musashi Mountain High School's third grade class in Goshogawara, there is only one member of the school's sumo club. This student tries to attract more members by being enthusiastic and sincere. Thanks to his efforts, four additional individuals join the club: judo team captain Kaoru Kiyokawa; pro wrestler Takayuki Kannai; Nanno Ippei, a skinny thug wannabe; and Raiden Goro, a giant but shy person who is also an expert in Go. The five of them train together and later participate in a competition against a professional sumo club.
