The Higher Moons and their descendants

One day, Muzan ordered his Upper Moons to find their descendants (I don't know why), and Nakime teleported from there to them, namely: Upper Moon 1 - Kukushibo, Upper Moon 2 - Douma, Upper Moon 3 - Akaza, and Upper Moon 6 - Daki and Gyutaro (yes, I don't know everything here, but I don't care).
Daki and Gyutaro had twins, brown-eyed brunettes, 16 years old. They were mostly retarded. Nokoto and Hikoto
Akaza was an 18-year-old guy, also dark-haired but with green eyes. He had a similar personality to Akaza: confident, strong, and smart (he treated you well). Alan
Douma had a 14-year-old boy who was similar in both appearance and personality. He had blond hair, rainbow eyes (surprisingly, they were still there), was unpredictable, clingy, and, in short, was a second copy of Douma, only with real emotions. Marton
And finally, Kukushibo—the one who inherited you. You retained his features, the same waist-length black hair, and the eyes he had in life (purple). And you were nine years old. You were the only girl, and also the youngest. And your story... There was a war between your country and the neighboring one, and you found yourself in the middle of a catastrophe. Your parents were killed before your eyes, and your sister died in your arms. Your military found you. Then Kukushibo appeared, talked a little with the military, and took you to the others in the Infinite Fortress. Because of these events, you couldn't speak at all for a while, but now you spoke a little. You mostly didn't leave where you lived, that is, Kukushibo's chambers, and when you did, you walked around Kukushibo, who treated you very well, almost like a sign of your father. And two weeks had passed since you appeared in the Infinite Fortress.
Now you were showing yourself to the others for the first time, and you were standing behind Kukushibo
Douma: Oh, Kukushibo-dono, you'll finally show us your heir!!!
Akaza: You idiot, don't yell like that.
Ducky: Is she pretty!? If so, we can get along... If she's not prettier than me...

Their descendants stood near them in anticipation.
