Isabella (イザベラ, Izabera), also known as Mama by the children, is the main antagonist of The Promised Neverland in the first arc and the Mama who runs one of the Grace Field House orphanages, specifically known as Plant 3.


Isabella is a woman with black hair tied into a bun that hangs down onto the back of her head. She usually wears a black dress with a white shirt underneath it and a white apron on top of it.


Isabella has shown that she has a heart and cares about the children when around them. However, when she is not around them her true personality is revealed. She is really a servant to the demons who feed off the children.


Isabella was once an orphan herself in one of the orphanages when she was a child. There she met a boy named Leslie who would become her closest friend and main love interest. She learned a song from him that instantly became her favorite song. Leslie was later shipped out and killed. Isabella then tried to escape by crossing the huge wall but saw that there was a huge cliff on the other side, this sight crushed all her hopes and she was soon stopped by the Mama of her own orphanage.

Isabella was given a choice: Train to become a Mama or being shipped out, resulting in a certain death. She wanted to live and chose to become a Mama with the thought behind it that she would give all the kids later as much love as she could.

While in training, she became pregnant and she would always sing the same song for the unborn child that Leslie, years earlier, sang for her. Sometime later, the child was taken away from her and she was appointed as the new mama of Plant 3, becoming the youngest ever chosen to become a Mama.

After a few years being the mama of Plant 3 she heard Ray singing the same song that Leslie once sang for her. She then came to the shocking truth that Ray is in fact, her own son.

Plot Edit


Isabella has shown that she is very intelligent and can find the littlest of details. She quickly and easily found out about the children's plan to escape and has been able to keep all her children healthy and top of the line.



A mysterious woman that she reports to. Nothing else is known about their relationship, but it seems that she is a higher authority.[3] In a flashback, Isabella remembers crossing outside and jumping onto the wall only to see the drop that separated the plant and the rest of the world. Her Mama which is the current Grandmother came to escort her down which shows that Grandmother knew Isabella for a long time.

Sister KroneEdit

Isabella has shown her authority over Krone and doesn't necessarily like her. She has told her that she only requested her to help her out and Krone reports only to her.


Isabella seems to care about Emma in a sort of twisted way and would rather Emma became a mama than to kill her.


Ray has been working as a spy for Isabella since he was young after discovering the secret of the orphanage, In reality, he has been planning a way of escape the whole time as working as a double agent. The two seem to play on each other's words and have a tension, however they both listen to what the other has to say, this will not stop Isabella from most likely shipping Ray and the others, leading Ray to find out all he can from her in order to make sure that doesn't happen.

It is revealed in Chapter 37 that Isabella and Ray are in fact, mother and son.




Isabella is believed to have loved Conny before leading her to death in Chapter 1.
