User blog:Nobody700/S-Class heroes and Humanity

As we have seen, throughout the series, multiple Humans have shown how strong they can be. Even C-Class heroes showed they can be badass. But S-Class heroes showed they can be far stronger then almost anyone. Even the weakest S-Class (King not included), are shown to be stronger then the worst demons. However, with the newest arc upon us, we see more and more people who haven't joined the HA, and may be S-Class worthy. How many S-Class heros can their be?
