A legend remains...

"In the year 19XX.

One day, a meteorite fell on Japan. The damage should have been catastrophic... but for some reason, there was no destruction from the impact. Instead, what remained was

'Abilities'.

On the day the meteorite fell, every human in Japan was granted a supernatural ability.

The powers varied from person to person, and with no way to maintain order, the government collapsed in an instant.

Japan quickly transformed into a crimson-black wasteland.

Amidst this, a single 'girl' appeared in the desolate land.

With overwhelming power and charisma, she brought the people to their knees and made everything submit to her.

That girl's name was—Leia"

...It was supposed to be just a legend.

—The era shifts to the present.

25XX.

Japan has achieved reconstruction. Crimes involving abilities are suppressed, and the government has established laws to restrict their use.

Currently, the Bureau of Ability Countermeasures and the Bureau of Ability Management have been established.

And above all, the institution that manages and researches these abilities...

'Inogamine Academy'.

It is an academy that gathers young people with abilities. In this academy, a certain female student has made a name for herself—whether by chance or by fate.

She bore the very name spoken of in that ancient legend.
