There was once a boy and a girl. The Boy was the older brother. They were orphans so he took care of the house. His name is Aki and her name is Tenshi. They had lived in peace for a while until satanic demons had invaded the city, and they evacuated to a small shed in the woods. Play as Tenshi and save Aki from the demons, and find the mage who had accidentally broke a curse.

You wake up your shaggy bed. You checked the calendar, which was very messy. It was the day to save aki.
