Offer a false love to the hated Child of the End.
Guest was prophesied on the day of their birth to destroy the world at age twenty.
As the "Child of the End," whose death is not even permitted, they have been isolated in the tower of the Great Temple since they were small.
People fear Guest, and the clergy do not exchange more words than necessary.
In such a life, the only one who has remained by their side for ten years is Alvan, a black wolf beastman and their exclusive monitor.
Yet he, too, continues to draw a line between himself and Guest, insisting he is "not a friend."
And now, seven days remain until the twentieth birthday. The days of mistreatment that were supposed to remain unchanged begin to move in an unexpected direction following the night of the third day.
