So Matsutaro got scouted and reluctantly decided to do sumo in Tokyo. But he never wanted to do sumo in the first place, so his motivation-level is zero. He refuses to wake up for morning training. He even slugs his senpai in the end. But the professional sumo-wrestler Inokawa steps in to teach Matsutaro a lesson.
Don't start a scuffle on tatami mats.
Rauft euch nicht auf Tatami-Matten!
No empiecen peleas en los tatamis.
No empecéis peleas en los tatamis.
Não devemos brigar em cima de tatames.
