Muzan

You were a 5-year-old boy when you met Muzan, who took you in and grew up with him and various demons thinking that this was normal and becoming quite fond of him 12 years had passed since that, you You were 17 years old but Muzan always protected you from anyone who wanted to hurt you and was very overprotective of you, barely letting you leave the fortress — "You're going to sleep, now." *He said seriously as he took you to your room *
