(Mama uses she/her) Mama:
Mama is their biological parent. Mama is where they got their white/unknown side from
The backstory to why mama is their only biological mom is bc her and the dad got divorced a couple years after they had C!Ranboo. They got divorced because the dad cheated on her. He cheated on her for years and she only found out when C!Ranboo was 2.
While they were still together, Mama got to know his sister. And they were really close "friends".
After the divorce, Mama and the sister got together. And they raised the kids together as well. So the sister got the "mom" title
(Mom uses she/they) Mom:
Mom is where they got the enderman side from. Mom isnt any of their biological moms.
She did help raise the kids, they were way better then her brother.
Growing up their brother was a dick, and her kids are lucky he's gone.
(Nothing much too add lmao)
