Summary of One Punch Man (OPM) Chapter 13
Chapter 13 is all about the Hero Association entrance exam, and oh boy, it’s a blast. Saitama and Genos show up to join the ranks of official heroes, but their contrasting performances steal the show. Genos, with his high-tech cyborg body, aces every written and physical test with robotic precision. Meanwhile, Saitama casually smashes every physical record by absurd margins, leaving the examiners dumbfounded, but he totally flunks the written part. The highlight is Saitama’s “serious” punch during the strength test, which obliterates the machine entirely. The Hero Association decides to rank Saitama as a lowly Class C hero, while Genos lands in S-Class, setting up a hilarious dynamic between them. Saitama’s complete indifference to rank is classic, and Genos’ blind admiration is both funny and endearing. Fans get a taste of the strange and sometimes unfair world of heroism, making you root even harder for our bald protagonist. By the end, you can’t wait to see how Saitama shakes up the hero world.
