One Punch Man Manga Online Chapter 51

In Chapter 51, titled Headgear, the story opens in the Entertainment District where a Hero Association representative named Zeimeet is out promoting with two female escorts, behaving smugly and asking for kisses. Suddenly, the infamous hero hunter Garou appears and violently knocks Zeimeet out with a punch, clearly unimpressed by the hero’s weakness. Garou is on the lookout for strong opponents and is frustrated by how easy his latest target fell. Not long after, Saitama enters the scene, quietly appearing behind Garou while out shopping. Garou mistakes Saitama for a hero sent to stop him and attacks without hesitation, landing a blow to Saitama’s shoulder. However, Saitama, irritated more than hurt, casually responds with the same exact move—knocking Garou out cold in one effortless strike.

The scene then takes a humorous turn, revealing that Saitama wasn’t even looking for a fight—he had simply been shopping for a wig. The next morning, Garou regains consciousness in a pile of trash, dazed and unable to clearly recall what happened. Back at Saitama’s apartment, he’s trying on the new wig in front of a confused Genos. Seeing the sudden hair on Saitama, Genos becomes inspired and immediately contacts Dr. Kuseno to ask about the possibility of getting a hair transplant himself. Saitama clarifies that the wig is just a disguise—he plans to enter an upcoming martial arts tournament under a fake name, and he wants Genos to come with him.
