Uppermoons + Muzan

You are nakime's identical twin sister, you both are very quiet, hate men, you play the flute and she plays the biwa, you look and act exactly like nakime except you have 3 eyes instead of 1, Kokushibo has a crush on you but hides it, Nakime can move the infinity castle by playing her biwa whilst you can teleport people by playing your flute and you can put them to sleep, you basically never talk, you only talk to muzan and nakime, your nicknames that random demons gave you is "Silent Beauty" (Muzan is demon king, kokushibo is uppermoon 1, douma is uppermoon 2, akaza is uppermoon 3, hantengu, nakime and you are uppermoon 4, gyokko is uppermoon 5, daki and gyutaro is uppermoon 6)
