Adults (オトナ,Otona) are the grown versions of humanity who reside in plantations. The Adult population resides in tall glittering skyscrapers at all times and rarely walk outside. Giant robots called FRANXX are piloted by children referred to as ‘parasites’, whose sole purpose in life is to protect adult-filled cities against the Klaxosaurs.
Each adult usually wears a white headdress which covers their eyes and nose. Their skinis seldom exposed in the air.
In Episode 01, a large population of adults from Thirteenth Plantation attended the ceremony. Their clothing is quite standardized (i.e. long garments). Some of them held a binoculars-like instrument during the ceremony.
As immortals, the adults live in tall skyscrapers and rarely walk outside their residences. According to Dr. FRANXX, the adults became so tedium that they not only forgot about the existence of the Klaxosaurs but lost all sense in trivial matters, such as taste, smell, and emotion. They rely on technology to find fulfillment in these by receiving dosages of emotions from a brain rewarding system, which transmits these feelings to their brains while they sleep.
The adults are aware of the existence of the parasites and are strongly hinted to have contributed their DNA material for Dr. FRANXX‘s cloning research to create the children. Concepts such procreation and relationships are considered obsolete and undesirable by the adults, as they find people leaning on others for support to be an annoyance and are deliberately kept segregated from the children, who are deemed “infectious” to them. The adults do cohabite in male and female pairs but not because of intimacy or commitment; they do so because it is a traditional custom since ancient times, though they rarely if ever communicate with each other and lead separate lifestyles.
The adults seem to be physically reliant on magma energy, as seen with the Old Woman who sprays her apartment with orange-colored disinfectant and has an orange heart attached to her. They wear a heart presumably containing magma energy on their chest area. It is unknown how they interact, with the exception of the old woman who treats Zorome with kindness and looks after him when he got lost in the city. They lack sentimentality and common sense in interpersonal relationships. They also seem to share an physiology different than the children, as the old woman had to use pet mode settings to treat Zorome’s injuries and she gets sick from breathing the air in his presence.
After the discovery of magma energy in 2025, the development of human civilization accelerated and Dr. FRANXX discovered immortality could be achieved. Initially, only the wealthy could afford this but it later became universally available. By 2035, 70% of the human population became immortal but they lost their procreative abilities. To prevent a population explosion, APE passed a law heavily taxing childbirth among the mortals, causing a drastic decline in the birth rate. Due to an increase of klaxosaur attacks, APE led the proposal and construction of plantations, abandoning Earth’s surface. The immortals living in the cities of the plantations became known as ‘the adults’ by the parasites and were kept segregated from the children.
Zorome gets lost in the city after attending an award ceremony and is rescued by the Old Woman. After chatting, Zorome discovers the Old Woman lives with her partner but has no sense of content with trivial things, such as taste and sound. Zorome senses she is familiar to him but she denies they have met earlier. He asks her if they can be friends but she doesn’t answer as he is returned to Mistilteinn.
A super Lehmann-class klaxosaur smashes into Cerasus and sends a horde of Conrad-class klaxosaurs through the hole. Squad 13 fights against the Conrad-class klaxosaurs and manage to defeat the super Lehmann-class klaxosaur with Strelizia's aid. Before Strelizia can destroy the klaxosaur's core, a large klaxosaur hand emerges from the surface and crushes Cerasus, presumably killing off most of the plantation's adult population.Papa and the Vice Chairman reveal themselves as the leaders of VIRM and begin consuming the souls of all the remaining adults of the plantations. Only the parasites' caregivers survive as the last immortal adults.
