Ilse Langnar

Ilse Langer is a deceased member of the Scouting Legion. She was a participant of the 34th expedition beyond the Walls and was in charge of the left wing of the second brigade. She wrote very useful information about her final moments in a notebook.

Personality
She seems to be quite emotional (as shown when she encounters the Titan), yet brave.

Story
Ilse was first introduced in a side chapter: Side Story: Ilse's Notebook. She was the sole survivor of a Titan attack. Her horse was killed and her 3D Maneuver Gear was severely damaged to a point she can't use it anymore. She runs away on foot to the north. She then runs into a Titan who strangely looks at her and starts bowing for her repeating Ymir's name, thinking Ilse is Ymir. After Ilse gets angry at him the Titan notices it's not Ymir and kills her. However, Ilse recorded her interaction with the Titan in a notebook, which is later found by Rivaille.
