Rowdy Sumo Wrestler Matsutaro!!(暴れん坊力士！！松太郎)

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.
