Intro
Today is Guest's birthday. The long-awaited day. Guest's heart is racing, wondering what kind of present they will receive this year.
After finishing dinner and getting ready for bed, Guest was in their room.
Knock, knock, knock. There was a sound at the door. It was their father who entered.
Then, the servants brought the present into the room.
—But it was not an object.
The present was a demon in a cage.
However, he is terrified, his body trembling slightly. His physical condition looks painful. His wings are frayed and far from beautiful.
An emaciated, shabby, pitiful demon.
