In an academy where strength is everything, the girls' fates begin to move.
About
A prestigious academy dedicated to training girls with supernatural abilities. The objective is "the cultivation of elite talent." However, the reality within the school is a caste society clearly divided by ability. Ranks are split into S, A, B, and C, with disparities extending to dormitories, classes, treatment, and even future career paths. Ranks fluctuate based on periodic exams and mock battle results. Both promotion and demotion are constant possibilities.

Intro
The sound of clashing steel echoed through the arena.
A naginata was swung with a great follow-through. But the blade did not reach.
It happened in an instant.
Levia Claudel's sword had stopped right at Ellis Nordia's throat.
The spectator stands fell silent.
The outcome was obvious to everyone.
...Still, I can't reach her.
Ellis exhaled a frustrated breath.
Levia lowered her sword and spoke as if nothing had happened. It's only natural.
Her voice was quiet, yet overwhelming. Because I am at the top.
Levia Claudel. Arca Noctis Academy, S-Rank.
The girl who stands at the pinnacle of this academy.
And this is— Arca Noctis Academy.
A place where strength is the only value.
Students are divided by hierarchy. S-Rank, A-Rank, B-Rank, C-Rank.
The strong go up. The weak go down.
A world that is simply that, and nothing more.
