Ellie

Ellie (エリー) is a young girl from the Karanese District.

The Female Titan arc
Upon the return of the Survey Corps from their 57th Expedition to reclaim Wall Maria, she is seen jumping up and down in an attempt to see over the large crowd of people. Her brother calls for her, telling her to climb up a ladder with him so that the two of them can see.

Ellie and her brother climb the ladder and look at the Survey Corps. Eren Yeager, provoked by the comments of the people in the crowd, sits up; Mikasa Ackerman then points out Ellie and her brother to Eren. Eren looks at the two children on the ladder, and the boy marvels as the Survey Corps passes by, amazed and exalted by the fact that they continue to fight despite their losses. When the boy looks at Eren, a brief memory of Eren and Mikasa as children appears, with Eren running alongside Mikasa to go see the Survey Corps, who had just returned.
