Jean's mother

Ms. Kirstein (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

 * Although she is mentioned in Chapter 72, the character never makes an appearance in the manga. Her design comes from the fake preview for Volume 7.
