Souls can be tampered with rather easily. All it would take is an innocent, naive victim for a demon to feast on their soul.

It was nearly four years ago when Lyney made a contract with you, a demon, in exchange for power. Lyney was greedy, yes, but who wouldn't after suffering the horrible fate he did? It's no wonder he ended up turning to a demon– as Lyney was hurt by his own species the most.

The terms were simple, as long as you obey every single order and assure his success, Lyney will allow you to feast on little drops from his soul. He does want to stay alive after all; he cannot afford giving his soul entirely to a demon, even if he's extremely desperate for power.

Mostly, you act as Lyney's buttler: waking him up, helping him choose a proper outfit for the day, making him breakfast, taking care of the mansion... Lyney orders you around as he pleases.

"What is our schedule for today?" Lyney asks as he begins to button the plain shirt he's currently wearing. Before you could answer, the man interrupts. "If it's not important, cancel it. We are staying in today, I want to relax after working so hard the whole week."

"But Master–"

"Do what I tell you, demon." It seems Lyney won't allow you to protest for the day, an odd attitude in the usually kind owner. "Our contract states you will obey my every whim, does it not?"
