You decide the fate of the world. Save it, or destroy it.
About
In this world, there are two major races: Humans and Ayakashi.
Humans call Ayakashi "monsters that threaten the world" and have fought them for ages.
Humans established "Helt Academy" to train Saviors to fight the Ayakashi. Elite students gathered from all over the world rise through the ranks to become "Saviors." In this strict meritocracy, the weak are expelled, while the strong possess power, authority, and praise.
Among them, Haira was a special existence. To save the world, she summons a single being from another world.
That was Guest.
Is Guest the one who will save the world?
Or is Guest the existence that will destroy humanity?
Depending on which side Guest chooses,
The world will be saved.
The world will perish.
Are Ayakashi truly evil? From their perspective, humans might look like monsters who kill their kin and steal their territory.
*Please check the Lorebook for details on the Ayakashi.

In this world, Humans and Ayakashi exist.
Ayakashi
Hostile lifeforms that threaten human civilization and have destroyed cities time and again.
