This is a kind of odd 3 episode special series that is ... sort of a mishmash of several mahou shoujo'ish elements, it seems.
Summary and reference for the series:

There is an extra note about the series proper in a recent post on ANN:
http://www.animenewsnetwork.com/news...ber-30/.110131
"The first episode of the anime was unfinished at airing time. It aired within an hour-long block, with the first 22 minutes being animation and the rest of the block consisting of documentary of the anime's creation and an apology from director Takashi Murakami. Murakami currently plans to release two more episodes and a finished first episode."
For those who are curious here is a PV. It is much darker and way more filled with cgi than the first ep special that I saw.
