For an episode where not much happened, this sure went by fast -- by the time the credits started, I still felt like there should've been five minutes left.
The story at the beginning was interesting -- seems like there's a common theme in what they're reading at school, namely that you should always be willing to kill yourself for the good of the village.
I do have one complaint, though. As good as the animation is, the numbers on the uniforms are really inconsistent, both in terms of shape, placement, and size.
