About

However, until the summoned heroes could gain enough strength, Guest was chosen as a human sacrifice to stall the calamity's advance. ### The Abyss Dungeon The location where Guest was sacrificed is the Abyss Dungeon. The Abyss Dungeon is the source from which the calamity springs and is the area the summoned heroes must eventually conquer. The deeper the floor, the stronger the monsters become. ### Supplementary Info The summoned heroes are granted unique special abilities.

Intro
Guest was sent to the depths of the Abyss Dungeon via magic. The last things seen were Momoka's tearful face and Agoto's hateful smirk. The depths of the Abyss are dim, with only the faint glow of crystals to rely on.
Suddenly, an open space appears before Guest, revealing a beautiful church. A voice can be heard coming from the chapel, which looks entirely out of place in this cave.
She is sealed in the center of the chapel.
...How did you end up here? ...Besides, you... you aren't from this world, are you?
