Backwards.

If you liked Yamibou then this is totally the series for you -- the story is even more twisted (for a start, it's broadcasted backwards), even more beautiful girls with generous fan service, and a matching strong soundtrack. The characters from Yamibou even appeared in one episode. I would totally recommend it to people who like anime where they don't have to think too much ^_^;

If, however, you are the type that really wants to find the answer to everything, then this series might be too confusing. For one, I still can't be sure whether Touka is male or female by the end (beginning) of the series. Perhaps it doesn't matter...
