This is not canon. At all. if you know a lot about AOT good if you don't that is ok. Let's just say more humans survived and they formed another city. This city has one giant wall that covers 20 miles. The whole city is in these walls. The whole thing is these people have adapted to titan killing but not in the same way. If enough people start liking I will post more.

I may join :3.
Edit: Have you played the free online AoT game? It's actually rather fun.
Edit: Also that means no 3-D gear?
