B-class: Suppression - A practical expert capable of resolving various incidents alone.

A-class: Tactical - A skilled individual capable of neutralizing a small elite unit alone. Villain organization executive level.

S-class: Disaster - A level capable of completely paralyzing a large city or changing the map. The Association's top star heroes and heads of villain organizations.

X-class: Out-of-Spec / Mythic - A disaster capable of destroying a nation or continent single-handedly. An absolute threat that the entire S-class battalion of the existing Hero Association can barely stop or seal at best.

Unmeasurable: Identity / Providence - Also called 'Those Chosen by God.' Absolute beings on a different dimension who transcend even X-class. A divine realm where limits cannot be defined by any measurement standards or specifications created by humans. The grade for god-like disasters within the worldview.

Hero

• A licensed ability user registered with the Association, operating within the boundaries of laws and regulations.
• They receive public cheers and financial support but are bound by the Association's instructions and discipline. Known as those who work with a true sense of justice... or so it is said.

Association - KHA

A group of 'Guardians of Justice' who protect the safety and peace of citizens. A state-authorized institution that exposes S-class star heroes to the public, allowing them to enjoy popularity comparable to celebrities, while controlling and managing ability users by grade.

Villain

• Those who destroy social systems and commit crimes due to their own desires, ideologies, or overload (rampage) of their abilities.
• They are absolute evil that tramples on the lives of others through self-interest and destructive impulses.

Villain Alliance - Shackles of the Abyss

Their goal is to collapse the Association, which pressures ability users with control, taxation, and identity registration, and to create a 'world of the law of the jungle where power is everything.' They commit powerful acts of terror and crime. A cruel and extreme anarchist/criminal group.

Magical Girl

• Girl warriors born out of the world's necessity after seeing the shortage of guardians in the Association.
• They focus more on magical beasts or monsters than villains, aiming to purify them rather than eliminate them.

Magical Girl

Unlike heroes and villains who receive abilities through awakening, this is a group that exerts powerful strength through 'contracts' based on the girls' purity. But, what if that power is bent or broken...? Could it be used for something else...
