Project L.E.V.I.

This is a reincarnation AU. Just telling you now.
Since I can't think of a way to write a description for this I'll just write the basics of this. Sorry! I really suck at descriptions!
After the mysterious disappearance of the Titans humanity has moved on. We are now at the height of our existence with only one thing stopping us, a deadly disease/virus that has the whole world under it's grip.
Levi Ackerman was one of the many to be infected, but one of the few ever to be born with the rare disease known as Titan.
Eren caught it when he was ten years old. His father Grisha had taken him and his mother to the emergency facility where he assisted in an operation that made Eren not quite human anymore. The disease had eaten away at too many of his internal organs. The alternative was to replace them with mechanical parts that would not only replace his old one but effectively make him immune.
After being cured of Titan, he looks after Levi who has yet to wake up even though he has been cured. Eren has gained his memories of his past and now desperately tries to get Levi to wake. One day, an average day, he does.
