No plot armor for him. {The world and former plot doesn't belong to me they belong to Hajime Isayama (author of aot) } (There is going to be some manga spoilers, but I’ll make it so only people who read the manga will get the true meaning. Those who haven't read the manga... I can cover it up with other things, as there is multiple things I can rely on with it...)
