|— Jean's mother's note to Jean|
Jean's mother is a stout, middle-aged woman. She has brown, shoulder length hair that she keeps in a tight ponytail in the back. As an average citizen of Trost, she usually wears a simple dress covered by a red apron.
She is a loving and caring mother, despite the insulting way Jean speaks to her. On several occasions, she has gone out of her way to make sure Jean has enough to eat and is enjoying his time or making friends.
Early one morning, Jean's mother is making breakfast for her and Jean. When he fails to come down after she has repeatedly called his name. She goes upstairs with an omelet she made still in the pan. Her intrusion infuriates Jean, he quickly forces her out of his room; slamming the door in her face.
Two years after Jean has left for military training, his squad is stationed in the Trost District to prepare for a likely attack on humanity's newest front line. As part of the training, the cadets are to evacuate the citizens, Jean's mother is among those who are evacuated.
Sometime after their training, Jean's mother makes her way to the cadets' barracks. She runs into Eren Jaeger and Mikasa Ackermann, and asks them whether the two of them have seen Jean. Shortly after, one of Jean's superiors lets her in. Worried, her motherly instincts take over and she begins bombarding him with questions. Embarrassed, Jean begins yelling at her; trying to get her to go home. She tries to give him a gift before she leaves, but he makes it painfully clear that he just wants her to go home.
She manages to hand the gift for Jean to the Garrison soldier who let her into the mess hall. In the gift was a note encouraging him to work hard and not be a burden on others, as well as an omelet she cooked for him. After seeing it, Jean thinks back to all the moments his mother was there for him. Because of this, he decides to make an omelet for the cook-off. After winning, Jean contemplates visiting his mother the next day.
The night before the Scout Regiment prepares to retake Wall Maria, Eren Jaeger mocks Jean at dinner by calling him "Jean-boy," which was the nickname that Jean's mother used when she visited him during training. Eren reminds Jean that he should be nicer to his mom.
- Jean Kirschtein - In his younger days, they shared a loving relationship. But as he got older, feeling stifled and confined, he began to resent his mother as well as his status in life. Because of this, he leaves to join the military in the hopes of joining the Military Police Regiment. Two years into his training, she unintentionally and indirectly helps Jean win a food competition against Sasha Braus. She has always cared for Jean; she even sent a letter, apples, and an omelet as a gift for him and his friends.
