Episode Title:
The Terrifying City.
Episode Description:
Saitama tries to come up with ideas for mentoring Genos, then rushes off to find a villain once learning that C-class heroes get dropped off the registry after a week of inactivity. Sonic demands to settle their alleged rivalry, but Saitama refuses. Tank-Top Tiger reproaches Saitama for his antics and tries to take credit for being a hero when Sonic attacks him for interfering between him and Saitama’s rivalry. Sonic then starts causing mayhem to force Saitama to fight him. Saitama realizes Sonic is doing villainous things and swiftly knocks him out with a tap on the back. Later that day, rumors of a monster skulking around the desolate Z-City reach the Hero Association. They send A-Class heroes Golden Ball and Spring Mustachio to investigate before they are taken out by the monster Kombu Infinity. While assumed to be the rumored monster, Kombu Infinity was actually attracted to Z-City by the rumor as well, but Saitama kills the monster and uses its remains for kombu soup. Sometime later, Genos informs Saitama that he is ranked 6th in popularity despite being in 17th place within the S-class, greatly annoying an envious Saitama.
