Shadow of Hope : An Attack on Titan Fanfiction

The Scout Regiment's support is waning. Eren is losing control of his intense power. The death count of soldiers rises with each excursion outside the safety of the walls. Many Regiment members lose their confidence and abandon ship. Only Levi's few loyal followers remain ambitious. Titan attacks, however, have decreased. On a personal mission, Levi discovers why. A cryptic soldier has taken matters into their own hands. Slaying many titans without struggle, movements free as the wind, this could be the hope humanity needs. The only thing the Regiment has to accomplish, is to identify the enigmatic commando.
