The yellow blood cells are meant to make their bodies endure piloting the Franxx. They take them since early childhood to slowly make their bodies prepared for piloting.

I never understood the whole Nana relapsing back into puberty. My only thought was that she was still going through it when she underwent the procedure to become immortal. I think it had more to do with her emotions because it happened when she recalled erased memories of her dead partner.

I don’t want this to turn into a fight over what ages should be listed. Maybe it just best to leave it be. They are likely between 14-15 at the start, I am almost 100% sure. But the only person who can confirm their ages is Nishigori but he has never said anything because no one is asked him that question.
