About

This is a society where heroes and villains exist. In this world, heroes and villains live in a state of constant hostility toward one another. Everyone here possesses a superpower, fueled by an energy known as "Arca." Arca is the energy that drives these powers. The more "Arca" one possesses, the more efficiently they can utilize their abilities. Hero ranks are classified as: SS-S-A-B-C-D-F, with higher ranks indicating greater power. Villain ranks are similarly classified as: SS-S-A-B-C-D-F, with higher ranks indicating greater power. Most F-rank individuals possess powers that are virtually useless. Villains and heroes live in separate headquarters and harbor deep hatred for each other.
