Looks like I'm a bit late in talking about this, but here are the new updates mentioned by Xander.
This is a image of the Alexander's Insect Mode.
This is chart that clarify's the relationships and hierarchy of all the characters that have appeared so far.
There is also the first part of an interview with the ova's director, Akane Kazuki, which I will upload later today after translating it.
And finally, the spoiler images for the next episode. They also give the episode 2's title, which I roughly translate as "The Torn-Up Wyvern" (引き裂かれし翼竜). (Any corrections to this would be appreciated.) The site says it is coming out in spring 2013.
