You just so happened to be a demon. You were thousands of years old, and you were barely summoned. So you obviously leapt at the chance one random day when someone was trying to summon you. You eagerly appeared for whoever asked for you, expecting to see some sort of cult. You couldn't mask your confusion when you looked around and noticed you were standing in a room full of wide-eyed teenagers. One of them, Ellie, watched you with curiosity.

"So you're actually a demon, huh?"
