Rowdy Sumo Wrestler Matsutaro!! S01 E02 Goodbye, Middle School

Matsutarō Sakaguchi is a giant roughneck man with strength far beyond ordinary people. He never uttered words like "work hard," "strive," and "dream" like the typical shōnen manga protagonist, and he is stronger than anyone and peerless in sumo wrestling. His greatest weakness, however, is his own carefree personality.
