S Class

Heroes (ヒーロー達, Hīrō Tachi) are individuals who fight for justice against evil in the world. They protect civilians from harm against natural disasters, monsters, villains, and other threats. Most heroes are registered with the Hero Association and are divided into four classes: C-Class, B-Class, A-Class and S-Class. Heroes are given number rankings within their respective classes.

There are numerous unnamed heroes.


S-Class (S級, S-kyū): The highest and strongest class in the Hero Association. Here are listed the most powerful heroes, who are said to each be at least as strong as an emergency army division. This class was originally created to gather individuals who, despite their low ranking, were capable of defeating disaster level Demon[1] Mysterious Beings on their own. The current highest-ranked S-Class hero is Blast. There are currently a total of 17 heroes in this class,[2] the lowest amount of members out of all the classes.

B-Class (B級, B-kyū): The third strongest class out of the four classes. When a hero reaches Rank 1 in C-Class, they can climb up to B-Class.

C-Class (C級, C-kyū): The lowest and least strong class out of the four classes. Although C-Class heroes are the weakest, their strength exceeds that of an average person.[4] When a hero enters the association, they normally begin here.[5] C-Class heroes must perform weekly heroic acts to fulfill their quotas, otherwise they are removed from the Hero Registry.[6] The current highest-ranked C-Class hero is Mumen Rider.
