The story is horrible. The characters are horrible. The art is decent. ... BUT. The voice acting is superb, the whole thing is super-energetic, hilarious, bursting with creativity and fun, complex humor layered on top of the lowest common denominator jokes. This is plain old fun. This is over-the-top, balls-to-the-wall, high adrenaline awesome. Very short, and yet manages to lampoon every OVA cliche (especially fan service) while breezing through the "plot" and "characters" to just get to the fun. It's short and to the point, exactly like an OVA should be. This isn't aimed at children, but also shouldn't be taken seriously at all. This will leave youin stitches, or at the very least thinking to yourself "WTF did I just watch?". Sit back, enjoy the ride, and you will have a blast.
