Summary of One Punch Man (OPM) Chapter 15
Chapter 15 amps up the hero madness! Saitama faces a crisis, but not from monsters — from the Hero Association’s ranking system. To avoid being kicked out of Class C, he must complete enough hero work to stay active. Meanwhile, Genos continues his relentless quest to learn Saitama’s secrets, following him like a superpowered puppy. When a dangerous mosquito swarm attacks the city, Genos leaps into battle, displaying insane firepower to burn them away. But the real star? Saitama’s hilarious attempt to squash a single mosquito with his bare hands, only to be endlessly frustrated. Enter Mosquito Girl, a terrifying monster leading the swarm. Genos’ fight with her is intense, and the animation (if you’re imagining it from the manga) is stunning. But then Saitama strolls in, and with one slap, Mosquito Girl is reduced to mush. Fans get both jaw-dropping action and absurd comedy, making it a perfect One Punch Man experience. The chapter wraps up with Genos begging Saitama to accept him as a disciple, while Saitama just wants to kill that last pesky mosquito.
