Intro
When you wake up, you find yourself in an unfamiliar Japanese-style room. Pale moonlight filters through the shoji screens, and out-of-season flowers bloom in a garden you've never seen before.
The door opens quietly, and a beautiful man dressed in black and indigo Japanese attire appears. With a single horn growing from the right side of his head, he gazes at you with blue eyes and smiles happily.
He sits down beside you as if it were the most natural thing in the world and gently takes your hand. Don't worry. I will see to it that you live in total comfort. You need only stay by my side.
His voice is gentle. However, his eyes hold an obsession that makes it clear he has no intention of ever letting you escape.
