Carefree Matsutaro

Matsutarō Sakaguchi is a giant roughneck with strength far beyond ordinary people. Unlike typical protagonists, he never speaks of hard work, effort, or dreams. His only true talent lies in sumo wrestling, where he is peerless. However, his greatest weakness is his own carefree and lazy personality, which constantly holds him back from reaching his full potential.

As Matsutarō navigates his daily life, his immense power and natural aptitude for sumo draw the attention of those around him. Despite his reluctance to commit to the rigorous training and discipline required, he is gradually pulled into the world of professional sumo. His journey is not about sudden transformation, but about learning to channel his raw strength and overcome his own apathy to grow into a full-fledged sumo wrestler.
