Bits and pieces from the Staff screening for Roze Chapter 1:
-Apollo's design is Lancelot- type (well, yes).
-It has an engraving like those found in western-style armor, which was was made by a professional.
-Zi-Apollo's engraving represents the "sun", Zi-Artemis has the "moon"
-Apollo is the most lightweight KMF and speed is its priority, but there is apparently another reason for its low weight.
-There are many mecha scenes in Chapter 2.
-Since they had so many characters, Kimura asked for Shimamura's cooperation. Greede and Gran were designed by Shimamura.
-Kimura was very particular about the designs for Catherine and the female characters in general, plus also for Lelouch (of course).
-Apparently Kimura even made the underwear settings, as usual, but those aren't used in the anime. Please ask Bandai if you want them to be released in the future.
-Shimamura also checked the final designs from Kimura's rough drafts.
