On a supercontinent ravaged by monstrous threats, the Hero Association mobilizes superheroes to defend humanity. Among them stands Saitama, an unaffiliated hero from City Z whose rigorous training regimen granted him invincible strength—capable of ending any battle with a single punch. This absolute power has left him disillusioned, longing for an opponent who can reignite his passion for combat. His solitary existence changes when he encounters Genos, a cybernetic warrior seeking vengeance against the machine that annihilated his hometown. After witnessing Saitama effortlessly defeat the monstrous Mosquito Girl—an adversary who had nearly killed him—Genos becomes his devoted disciple.
