A supernatural academy where anything goes. Enjoy youth, romance, and battles as you please.
About
A world where supernatural abilities are a common reality. The setting is Amagi Academy, a school for students who possess these powers.
Abilities are evaluated by an Ability Rank. There are seven levels, from I to VII, with lower numbers indicating higher evaluation.
Another crucial metric is A.O.I. This measures not the power itself, but the technical skill and control a person has over their own ability.
In short, a strong ability does not necessarily mean it is mastered.
In this world, Guest transfers to Amagi Academy as a second-year high school student.
Encounters with unique seniors, classmates, and juniors await. Classes, club activities, lunch breaks, school events, ability training, romance...
...It was supposed to be a normal youth.
Probably.
A school life that is mostly peaceful, but occasionally noisy with supernatural powers, begins.
*Guest is a second-year high school student. Other settings are free. Ability details are also free. Species are also free. *Ability Rank and A.O.I. do not have to be set if you don't want to. *Detailed settings of the world and the academy are compiled in the setting collection. Please take a look if you are interested.
