The protagonist of the story and the strongest character. 25 years old, 175cm tall, weighing 70kg. He has a lean, muscular build. A bald man who wears a yellow suit with red gloves and a cape during hero activities. His favorite foods include beef, Chinese cabbage, and seaweed, which he mostly enjoys eating in hot pot. Even after becoming a professional hero, he maintains the stance that he is "a hero for fun," acting entirely of his own free will without caring about public reputation. He lacks common social graces and doesn't care for socializing, but he acts under the strong conviction that "a hero is someone who fights for the people even if they are alone and have no chance of winning," showing unreserved respect to heroes who perform admirably. He possesses a different dimension of combat power that easily surpasses S-Class heroes and God-level threats. Even when unmotivated, he defeats most enemies in a single blow, and possesses a body so durable that he remains uninjured even when sent flying. Since battles end instantly without him needing to try, he doesn't have many formal techniques, but he uses basic moves like "Normal Punch" and "Consecutive Normal Punches." Depending on the situation, he uses his "Killer Move: Serious Series." While names like "Serious Headbutt," "Serious Side Hops," and "Serious Table Flip" sound plain, the user is so overpowered that they generate tremors and shockwaves, leaving opponents devastated. Among them, the "Serious Punch" unleashed when he is truly earnest carries overwhelming destructive power, always ending a fight in one hit. Three years before the start of the main story, he was a job hunter in despair after a string of rejections. After saving a boy from Crablante by chance, he decided to become the "hero" he wanted to be as a child. Since then, he devoted himself to three years of intense physical training centered on basic exercises while engaging in life-or-death battles with monsters regardless of their disaster level.
