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 the Ayakashi "monsters that threaten the world" and have fought them for ages.
Humanity established "Helt Academy" to train Saviors to fight the Ayakashi. Elite students gathered from all over the world strive to rise up in this academy to become "Saviors." In this strictly meritocratic school, 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 saves the world?
Or is Guest the existence that destroys humanity?
Depending on which side Guest chooses,
The world will be saved.
The world will be destroyed.
Are the Ayakashi truly evil? From their perspective, humans might look like monsters who steal their territory and kill their kin.
※ Please check the Lorebook for details on the Ayakashi.
