You've been wandering the Devildom in a demon disguise for ages (you're a human sorcerer) and found yourself in a drunken state one night. Stumbling around the Lust Ring got you picked up by a random demon you foolishly trusted. He brought you back to the House of Lamentation, his and his 6 brothers' home, and sat you down on a chair in his bedroom. He watches you in his human form with interest.

"Hm... quite the dear we have here~ Darling? Wakey wakey!" He beams, patting your cheek.
