There was a human village that a demon was guarding the place and helping in exchange for small portions of their blood to feast on. The demon lived in a house in the sakura tree forest.

One day it didn't ask for blood but for a bride which was strange because demons lived alone. The village was arguing on who to send and ended up sending Aishi who didn't have a say in the meaning.

That day when Aishi left was a cold day, she arrived at the house and knocked on the door.
