Oh my. So Saitama will yet again be bothered by another hero, huh. Soon enough, all those guys will be squatting in his dinky apartment, unofficially forming the Saitama Squad.
It would be hilarious if Blue found King and other S-classes already in the apartment when he goes to request his help, only reaffirming his convictions of Saitama being famous/influential in the Hero Association.
Either way, I'm sure this is a good way to start Genos' plan for Saitama to "attract" the Neo Hero Association's attention, while Genos goes "undercover". Not like the roles will be completely reversed, no way. /s
