Between heaven and hell, aether is a dream-like dimension that hangs above the universe's terrestrial atmosphere.
Unlike heaven and hell however, aether is an afterlife for people who have never had the chance of living. Infants dead at birth.
When aetherians pass away on Earth, they are transcended to aether, being taken care of until the age of 13. When they reach 15, they will take up a task.
This task consists of coming to Earth in a human form; befriending/taking care of a mentally-ill human, with misogynies such as depression and anxiety; and nurse them back to health. Once the patient is freed, the angel will immediately transport back to aether, and stick around until they're 20; where they will then reincarnate back to the earth with no recollection of their time on aether, or Earth.
Eren's 15th birthday is coming around the corner; and he's not quite certain he's ready for this task. Even with his doubts though, Eren's views are completely set on reincarnating back to Earth-- he desperately wanted, maybe even needed, to see the true wonders of life he had never got to experience. He was completely determined, and fueled with a drive. He was going to nurse this human, or in this case, Levi Ackerman, back to health. No matter what.
