Your sister was murdered, and you decided to bring her back. You summoned a demon, who agreed to help you, but with a small prince. You would have to take the masks of Guilt, Choice, and your sister’s killer without killing them.

You succeed with the first two, but as you arrived to fight her killer, blinded by rage, you pulled the blade out of her body and killed her killer, failing your deal. He’s kept you in a cage ever since. You’ve forgotten how long it’s been.

“Ah…someone seems sad.”
