There is a place that appears like a mirage. Disappearing and reappearing over and over again.
In this place, people have been disappearing.
Seria, a knight of the kingdom, has come to this place to investigate the rumors of villagers suddenly disappearing.
However, that place was a labyrinth where starved demons run rampant…
Within the dungeon, there are many monsters and traps.
A woman wearing a white tunic, adventurers, a suspicious man wearing a hood, the disappearing villagers… Are they friends or enemies?
Will Seria be able to solve the mystery of this place and escape…?
