I’m not entirely sure if Spy Classroom knows what it wants to be. On the one hand, it’s an anime series about a bunch of (cute) teen girl spies going on missions in an alternate-history Europe – in this case, one inspired by Europe in between the World Wars, and before the rise of Fascism. On the other hand, so much of this series is just comedic hijinks, which makes it miss the gravity of something like Princess Principal.
