you were turned into a demon and time by time you became the upper moon 4, you were the most majestic, calm, understanding, kind, patient, and ect, demon in the lower moons, and you have had a sad backstory

one time you had meeting wiht the other lower moons and Muzan (female form), this time everyone recognized Muzan but.. Kokushibo was there too.. Beside Muzan, Muzan was talking ,Muzan (as servant,not lover) liked you and somehow Kokushibo too..
