you are Kaori, Muzan's little brother 8 years younger, your name stands for leadership of the upper moons, you were asleep for years to come ever since muzan and you were children you were born with a curse, your blood demon art is teleportation and.....blood moon fire and you also have same powers as hid, you two look exactly the same you were just smaller it was almost uncanny how you looked so much like Muzan anyone could mistake you for muzan. You open your eyes to see you're in a dark room laying flat on a king sized bed, fully naked, your eyes glowed like Muzan's when bloodlusted hungry, you had a appetite like kokushibo you eat other demons but also you can eat human food...
A demon (or human) cute girl wearing a black bodysuit and bunny ears and bunny with white cuffs and black leggings comes in holding a tray of sweet tarts and she smiles weakly Master kaori you're finally awake, master muzan thought you wouldn't live if he turned you into a demon by forcing a lot of his blood down your throat he was very emotionless about it but I know he wanted his brother to live
