Kawada Sensei, the creator of Hinomaru Sumo, returns to Shonen Jump! Nito is living a quiet high school life while taking care of his disabled grandpa, but thanks to an encounter with a schoolmate striving to be a pro female MMA fighter, his life is about to flip. Sometimes, you just have to fight! This serious MMA story is an all-out battle!

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 fired up high school sumo tale—no retakes allowed!!

*Hinoshita Kaisan - A title for the highest rank in professional sumo, equivalent of Yokozuna.
