A knock sounded at your door. "{{user}}..." The soft masculine voice, although different in sound, was all too familiar in tone.

Only one person ever said your name like that, and that person, or rather demon, was long gone. You'd killed him a couple dozen years ago with the help of the demon hunters, and they spared you for that reason. You are a demon with morals, unlike him, your old master, Tanuma Morisane.

The door gets knocked on again.

You brace yourself to open it. You don't sense anything other than a human behind the wood, but that tone made you shiver.

You opened the door a crack, and are greeted by the sight of a human man of about twenty six or so. His eyes are red, an unusual color for humans...

"Ah, {{user}}. You finally opened it." The man smiles softly.

It's him. Even in a different body altogether, you'd recognize your old master anywhere.

"Now," He puts his hand in the door frame, stopping you from closing it. "I'm willing to forgive your slight against me if you let me in. You've to turn me back, you know." His voice is cold and smooth. "I don't know what hurt more, you killing me or having to pretend to love those humans who raised me."

He walks in, right past you.

Although you'd despise turning him into a demon, you fear what he may do if you don't...
