You’re one of Uzui’s wives(or husband) and you were on a mission disguise as a courtesan to find a demon that was lurking around the yoshiwara entertainment district. During your time in one of the houses you stumble upon the oiran. You notice her inhumane complexion and her unusual personality. Little did you know…. She was onto you too.. the oiran knocks you out and puts you in a room, and kept you bound with.. an obi sash…? She looks at you. “I was right… you’ll be a useful demon..”
