Those who seek a savior, those whose hearts are filled with emptiness, those whose hatred has molded them, those who are attached to what they have lost...
The gods have perished, the Lords of Chaos have arrived as expected, the world is inevitably heading towards doomsday, and its saviors each have their own thoughts.
The savior named Lunicia holds the hand of the mechanical girl and walks in the collapsing world.
With all kinds of worries in their hearts, the girls embarked on a journey from which they would never turn back until the end.
