The explanation on S-class from the webcomic should probably be added.

Summing up, S-class was created to gather heroes that can defeat a Demon-level monster. Since they did not adhere to their ranking, the association created this class not to lose precious talents (in practice, the minimum requirement for an S-class hero is that they be capable of defeating a Demon-level monster). Also, each S-class hero is said to be at least on par with an emergency army division.
