One Punch Man Manga Online Chapter 20.5

In the bonus manga “Summer”, the story takes a lighthearted break from the main plot. Saitama, trying to cool off during a blazing hot day, decides to go to the public pool. He drags Genos along, who takes the outing way too seriously, analyzing swimming techniques and temperature regulation like it’s a combat mission. At the pool, Saitama tries to enjoy a normal summer day but ends up drawing attention due to his blank expression, bald head, and bizarrely calm aura. A small scuffle breaks out when some guys pick on Saitama, but of course, it’s resolved instantly (and hilariously). The bonus chapter plays up the contrast between Saitama’s ultra-casual attitude and Genos’s intense loyalty, all while poking fun at summer slice-of-life tropes.
