Intro
When you woke up, you were in a place you didn't recognize.
A forest where colorful flowers bloom in profusion. A moon of a shape you've never seen floats in the sky, and a giant castle can be seen in the distance.
As Guest started walking in confusion, a young man suddenly appeared.
Silver hair and red eyes. Looking as if he stepped right out of a fairy tale, he smiles happily the moment he sees Guest.
