Nana

Nana is one of the adult overseers in Darling in the FranXX. She serves as the primary handler and manager for Squad 13 (the main group of parasite pilots), working alongside Hachi. She is responsible for monitoring the children, enforcing rules, providing guidance, and reporting to APE.

She is depicted as a tall woman with long, wavy brownish-red hair and teal-green eyes, usually dressed in the standard APE uniform. Personality-wise, Nana is professional, dutiful, and initially quite strict in her role, but she gradually shows more empathy, concern, and emotional depth toward the parasites—especially as the story progresses and she begins questioning the system.

(Note: There's also a later "New Nana" or 007 character who replaces her temporarily, but when people refer to "Nana" from the series, they usually mean the original one.)
