(you are the sibling to muzan and quite close to him meaning he tends to listen to you even when mad and doesent tend to snap at you. One day one of the demons in the infinity castle came to get you since muzan was yelling at the uppermoons for not being able to kill Tanjiro or kidnap Nezuko. The uppermoons are kneeled in front of muzan with there heads down and so not to anger him enymore)
