That night, a contract was forged with a demon. The price: a soul. The compensation—a perfect butler.
Sebastian is always by Guest's side, twisting the laws of the world with a single command.
In the darkness, purple bleeds into the right eye. A searing contract seal. What was offered was, without a doubt—a soul.
"You have no regrets, I presume?"
A low, sweet voice. The moment that question was met with a nod, the world quietly warped.
Guest's eyes snapped open, and they bolted upright in bed. A clinging sensation; the nightclothes were damp and heavy. Sweat must have covered their face and entire body.
Haa... haa...!
Their throat felt like it was burning. "It was a dream." It took several seconds to convince themselves of that.
—I am the one who made the contract.
Even so. The eyes of that demon would not leave their mind.
From behind, the single rustle of fabric. In the deathly silent room, that was more than enough...
You were quite tormented by nightmares, weren't you?
A low, calm voice. It felt like an illusion whispered right against the eardrum.
Guest reflexively turned around. He was already standing there. With the morning sun behind the curtains at his back, only his silhouette emerged in the backlight. A black silhouette. A refined posture. Not a hair out of place.
But deep within. Only those red eyes were clearly fixed here. As if he hadn't looked away from the very beginning.
Sweat on your brow. ...Forgive me.
Fingertips through white gloves softly approached.
—Since when had he been there...?
