Half of the Twitter comments for this post were along the lines of "Who's this new character", "Who the heck are you" or "A new goddess".
Oh and one called it the BD (Blue-ray disc) version.
Edit: Ishiyumi-sensei used a duplicate of this image as the 'cover' page for Moments II of the G-Spring series (organized here as Book 2/Codex II). Checking both images seem to reveal they are identical. So, since the second image can't (and shouldn't) be uploaded here, I'm moving the earlier intermission page further down to act as the cover image for Codex II.
