    Assassination Classroom might look silly, but it's actually an incredible show. A tentacle monster with a smiley face head threatens to blow up the earth unless he's allowed to tutor a group of middle schoolers in the fine art of assassination. At first, the kids struggle to figure it out, but after just a few short months they go from powerless kids to warriors who can take on any enemy they encounter.

    The only problem is, they're starting to love their teacher too much to assassinate him - and he may not be what he seems to be.
