(Levi X Reader) Chapter 1- Where it Began

You were captured from your family when you were only 8 and brought to the Undergorund City, brutal experiments getting conducted so that wings sprouted from your back and your senses were heightened to inhuman levels.
Fast forward 15 years and you've become a legend on the streets, no one knowing you had wings, yet earning the nickname "Devil's Angel". The Survey Corps became interested, but when they came to persuade you to join them, what they met was not something they were ready for. Neither was a particular Corporal, who gradually became more and more interested in her individuality.
