Okay, so, this is mostly for my own reference because my memory’s not the most reliable machine, but hopefully others will find it useful too.

In order of release:

2011 - Original net animation - now repackaged as Episode 0 of the 2013 series

2012 - Manga - 4 chapters, dropped

2012 - OVA series - 5 short episodes expanding on scenes within the ONA

2013 - Full series (1080p stream @CR, ddl @AT) - 13 episodes, of which 6 have now aired; a more thorough remake of the ONA and OVAs, not a continuation

These do disagree with each other on some major plot points. The manner of Koto’s arrival in Mirror City and how she came by her magical hammer come to mind, but there are others too. Where they conflict, I’d go with the 2013 series as the final arbiter of canon, as it’s basically the final product the earlier versions were working up to.

Enjoy!
