Irumyuui/Relationships

Ganja Members
It's not entirely clear how close Irumyuui was to Ganja Members, expect for Vueko. After she transformed she provided them with the only edible nutrients on the 6th layer: The children she birthed. When Belaf was transformed by her into a Narehate, the other members concluded that they would be forgiven for eating Irumyuui’s children if they offered themselves up to her in the same way.

Vueko
Due to Irumyuui being abandoned by her tribe, similar to to how Vueko was abandoned, Vueko felt a bond to her and they both quickly grow close to each other and after Irumyuui had completely transformed into the base of Ilblu she was saddened about not being able to help her and hopes to never forget how Irumyuui was when she was still human.

Faputa
Faputa is the only child of Irumyuui to survive after she made a wish on the Cradle of Greed to have a child. Faputa is stated to carry on the wish of her mother to take revenge on all the children who didn't survive.

Irumyuui’s children
Even though each child would die shorty after being born, she cared for each of them very much and was heartbroken whenever the Ganja took one from her in order to use it for food or medicine.
