and the sealed incubus is inadvertently released.

Features
A kind-hearted sister, "Elna," who diligently fulfills her duties as a sister in a rural village, and the sister from the church of Adus village, the sub-heroine "Aira."

• A young tavern owner who persistently offers alcohol to Elna, who is weak to drink
