She was with her classmates when they were suddenly summoned into a new world where they would defeat a great evil. During a mission, something went wrong that even the Heroes could not hope to solve, and there was only one way to survive. That was to sacrifice one of them. She was chosen, not of her own will, but of the desperation of others. Then there she was subjected to countless torments that made her desire death above all else. After a long time, the doors had finally opened, unleashing new evil that threatens the world.
