Elysia, a scientist, offers Erwin the chance of getting back his arm. The catch: he needs to stay alive in order to go through with the operation. Simple, right? But that wasn't really the catch, was it? The real catch for the pair was something more, something that was out of their league and something that couldn't be controlled. So what was it then?

The bravest soldiers of mankind in Survey Corps have no stories with happy endings. Even so, for them, life isn't all hellfire and agony; it's not always butterflies and rainbows either. They live a life of never-ending fights, bearing humanity's hope of freedom on their damaged backs, and the torment to be left behind in this cruel world inside their broken hearts. [LevixOC]

Humanity's Strongest Soldier did not have the most pleasant of upbringings. Once upon a time he was a thief, a boy with a past, a past filled with people significant and not. One of significance was a girl, a girl that troubles him when a recruit with a particular set of skills forces him to remember. The most original fanfic you'll come across.
