Heroes/Hero Association

The Heroes Association, also known as the Superhero Society, is an organization founded by the multi-millionaire Chinner that manages all of Japan's superheroes. Chinner has also established the National Superhero Registry, the database that embraces every recognized superhero in Japan. The Association uses a class-system, with 4 classes and ranks within those classes, to organize every superhero accordingly.

History
Three years berfore the current storyline, the Heroes Association was founded by multi-millionaire Chinner whose grandchild was attacked by a mysterious being and saved by a passing man. After hearing what happened, Chinner came up with the idea and founded the Heroes Association and the National Superhero Registry from private funds.

National Superhero Registry
The National Superhero Registry is a database that contains the names of every officially recognized superhero in Japan. Any person not registered in the National Superhero Registry is not recognized as a hero and as such is always looked upon as a delusional weirdo, regardless of how many times they save the world.
