Jean's mother

Joshi Kirushutain (女史キルシュタイン) is the mother of Jean Kirstein.

Appearance
Ms. Kirstein 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.

Return to Shiganshina arc
The night before the Survey Corps prepares to retake Wall Maria, Eren mocks Jean at dinner by calling him "Jeanie", which was the nickname that Ms. Kirstein used when she visited him during training. He also reminds Jean that he should be nicer with his mom.

Trivia

 * There is a canon conflict in the information available about Ms. Kirstein. The character can be considered canon because she was drawn by Hajime Isayama and her design appeared in the fake preview for Volume 7 of the manga. However, her only appearance so far took place in the OVA A Sudden Visitor: The Torturous Curse of Adolescence, a non-canon source. In Chapter 72 of the manga, Eren makes some references to the events of the OVA, by calling Jean "Jeanie" (ジャン坊) and warning him to be nicer with his mom; both phrases used in A Sudden Visitor. Since the OVA was created as a comedic spin-off of the anime, it is unlikely that the whole story can be considered canon, but it is evident that Ms. Kirstein's participation is not far from the canon continuity.
