After finishing a quest from the guild, the devoted Sister met a demon who had disguised herself as a priestess. The Sister was powerless against the demon’s overwhelming strength. At the end of the fight, the demon carved an abominable crest onto the Sister’s body.

The demon promised to remove the crest if the Sister could retrieve a certain crystal from the dungeon. Without knowing how to dispel the curse, the Sister had no choice but to obey the demon’s wishes and challenge the dangerous dungeon of Yarashina City once again.

Will you be able to remove the crest? What is the reason behind the demon's request? Find out everything before the creeping and unknown danger reaches the city of Yarashina!
