The Crimson Harmony (Shingeki no Kyojin/Attack on Titan fanfic)

It was thought to be impossible to befriend a titan until the Survey Corps found a mysterious girl living in a forest outside the walls. The titan she had befriended was killed and after being named Ria, she was taken back into the walls. Ria was finally accepted and trained by Levi. She seemed to have a confused mind for she kept thinking that titans were her family. However, after an incident, her thoughts became clear. Ria is now trying to fit the puzzle pieces together for her identity and the truth. Why was Ria living outside the walls? How could she befriend the titans? What was her past? In the end, she goes through lots of adventure, action, and emotions to find out the answers she was searching for.
