I rather despise that genre, because they're all the same. Once you've seen one, you might as well have seen them all. They re-use the same tropes and devices, and don't much original fare to offer.
This series takes those tropes, and irreverently plays with them, providing parody and lots of unexpected content. And trolling. So bad it hurts. I haven't had so many laughs over an anime since "Daily Lives of High School Boys" (which, incidentally, has the same director; who's also the guy who did Gintama).
The princess isn't a sexy teen girl (she's not even cute enough to be a loli) and the sexy teen girl isn't actually even….
The cute animal mascot (which EVERY hero group must have), is at war with the hero.
And, erm, "crotch problems" take center stage. It's all about balls here, folks.
Basically, you can watch it without knowing quite knowing what's going to happen next. Except that it's not going to quite turn out the way it's "supposed to", or at least, not the way we've been conditioned to expect.
This is a comedy that's given me lots of healthy laughs so far; I've watched through half the episodes, and look forward to seeing what curve'balls' are thrown at me next.
