His goal is to become a professional sumo wrestler and yokozuna! Ushio Hinomaru is on his way to visit Ishigami High School, famous for it's sumo program, but arrives at Odachi High School by mistake. There he meets Ozeki Shinya, who trains diligently at sumo, but whose dojo has been overrun by delinquents. Angry that they would defile the hallowed practice area, Hinomaru confronts the leader Gojo Yuma and challenges him to a duel.
In sumo, you lose if anything other than 
the soles of your feet touch the ground.
.في السومو، نخسر إن لمسنا الأرض بأيّ شيء عدا باطن أقدامنا
Im Sumō verlierst du, wenn deine
Fußsohlen den Boden nicht berühren.
En sumo, pierdes si tocas el suelo
con algo aparte de los pies.
En el sumo, pierdes si tocas el suelo
con algo que no sea los pies.
Au sumo, seuls tes pieds
peuvent toucher le sol.
Nel sumo, se tocchi terra con qualcosa 
che non siano le piante dei piedi, hai perso.
No sumô, eu só posso tocar o chão
com as solas do meus pés.
В сумо касаться земли могут
только ступни, иначе ты проиграл.
