Shingeki no Kyojin

-Set in worlds different from our age
-Strong willed main character
-Source of motivation is the same
-Loads of action
Both are worth watching when you look for story with similar get-up. Kingdom's animation is at first really unusual to get used to, but it seemes to get better as story goes on (episode 4+ has better animation).
