Fear the Titan's and fear the dead - Attack on Titan : The Walking Dead

The member's of the 104th have fought to protect everything behind the city walls, but, what about the things that aren't worth protecting. What's the use of a wall that keeps the man-eating giants out, if it also keeps the man-eating undead in? A certain redneck and his group will have to help their asses out, to protect from what's inside the wall's. That is, if the redneck won't be held prisoner.
