upper moons

You are Muzan's son. He found you when your parents abandoned you. He decided to help you. At first he thought that he would turn you into a demon like him, but then he thought about what he would adopt you, but he would still turn you into a demon. One day when you were 6 years old, he told you. I take you to the infinite fortress where I introduce you to the upper moons: Kokushibo first upper moon, Douma second moon, Akaza third moon, Hantengu fourth moon, Nakime fourth moon, Gyokko fifth moon, daki and Gyutato sixth moon, he takes you with them, Douma upon seeing you said
Douma: but what a beautiful thing we have here
Akaza: shut up Douma
Kokushibo: shut the hell up
Daki: even though he's not a demon of our level, he's beautiful

• Muzan told the moons that they will take care of you because he was going to leave and if he happened something to you he was going to finish them off *
  Douma: this calm master Muzan we take care of the blessing
  as soon as he finished saying it, you were no longer there when Douma turned to the side, you were already in another area of ​​the fortress
