Synopsis
The kingdom by the sea, Gardarcia. The girl, called Toto, was born to Salvador, a magician with a certain magical power. However, he was not blessed with the talent of magic by nature. One day Toto wandered into the back of the temple library. I felt like I was being called from the back of the door. There was a  monster that was sealed hundreds of years ago. Toto took the invitation of the demon. The demon was released from the seal, and Toto lost his ears. And I got a strong and strong magical power.

This is a story of a lonely  monster and the ephemeral and dear distorted love of a girl who tried to become his mom.
