The non-athletic head of the school newspaper department participates in various club activities, including a number of sports clubs, with disastrously hilarious results.

It's every high school baseball team's dream to go to the legendary Koshien Stadium Tournament. For the first time in years, Seido High School has a chance—star player Gorilla Matsui has finally given the team an opportunity to succeed. Most delighted at this prospect is Principal Kocho. However, the Head teacher reveals to him that the first game will be played against the Gedo High School, infamous for brutally killing all their opponents. Kocho instantly loses all hope, both for his students' lives and of winning the tournament.

It is a divine ritual, a martial art, a combat sport—it's sumo!! A "small" new student, Ushio Hinomaru, appears before the weak little sumo club of Oodachi High School! The words "big" and "heavy" are the rules to this sport, which does not fit this newbie any inch, but this guy goes and does what...!? Ushio and the small sumo club climbs its way to the top! The goal is Hinoshita Kaisan (A title for the highest rank in professional sumo, equivalent of Yokozuna)! A fired up high school sumo tale—no retakes allowed!!

There is a new student at Oobu High School. His name is Yakuda Daigo. With his buff body and a tough looking face that can make every one run, soon rumors spread about him. Some says he's a gang leader, others say he is involved with Yakuza business, still more say he rapes, steals and likes beating people. There are only a handful of people who know who Yakuda really is, including Manami-a. She is a girl Yakuda fell in love with. Yakuda loves to cook and he likes cute things. He also enjoys gardening, crafting and adores pets. He is a very caring person. He always carries around a cute sewing kit and a cute first-aid kit around. However, with many unfortunate events, he often gets involved with a gang fight or a criminal, along with other coincidental things that happens around him. People always assume the worse for him. Will everyone find out who he really is?
