Hīrō Kyōkai (Hero Association) also known as the Superhero Society, is an organization founded by the multi-millionaire Agoni that manages all of the cities' superheroes.[1] Agoni has also established the National Superhero Registry, the database that embraces every recognized superhero. The Association uses a class system, with 4 classes and ranks within those classes (Classes A, B, C and S), to organize every superhero accordingly.
