Wings of Freedom (Levi X Reader)

(Y/n) (L/n) woke up in a forest, with no memories of where she came from. The only thing she knew was her name, age, her abilities and her wings. With giant human-like beings walking around the ground she was glad to have her wings to fly away from them.

She eventually meets a group of people that ventured outside the walls, after being forced to join them her and the short raven captain never got along, until they got to know each other.
