Okay, based on
this image, which is from
the picture drama on the last DVD (thanks to
nokiirat!),
libekory and I translated the text on the side of the images...
Image 1: In a Knightmare development laboratory somewhere in Japan. The Guren's right arm has been remodeled into a drill, with Kallen as the test pilot. The one responsible for this development is Rakshata. Even though there is no longer an imperial family to serve, it seems that Guilford -- whose eyesight has completely recovered -- continues to stand by Cornelia.
Image 2: The last time we saw them, they were near Britannia. Nina, Lloyd, Cecile are working at the same research and development institution. Arthur has been taken in by Cecile, who has brought him along. In front of Nina is a dubious-looking treat made by Cecile. Nina is on a long-distance call with Milly, who is still a reporter in Japan. Gino, who is no longer nobility and no longer a Rounds, has decided to go on a trip around the world, and seems to have just returned from Central America, from his attire.
Image 3: It seems that a little time has passed since the last time we saw the United Federation of Nations. The representatives of every nation represented in the UFN have gathered to for this conference.
It looks like they might be repurposing the Guren for construction work or something... Gino is a doof, as always. And who is that little blonde girl next to Nunnally?!
