On this episode, the school gets under attacked by units. Later, Tooru and his partner fights against the attack leader.
So the action was kinda random because the attack on the school wasn't introduced. I also almost thought I got behind on a episode because of the lack, somehow. Although they already gave a hint about it beforehand but that wasn't too clear. Other than that, it was pretty much all action along with more details on the antagonist. In conclusion, cool action and some more details about the antagonist.
