While complete scans probably won’t surface until Famitsu’s digital release (about ten and a half hours from now), a few more shots of the AA6 article have surfaced, giving us a (partial) look at the game’s key art and the mysterious woman within! (The bottom scan also has a comparison between Phoenix’s AA5 and AA6 models.)
While the magazine doesn’t reveal her name or who she is, it explains that she appears in court shortly after Phoenix objects to an all-too-fast verdict. She seems to be self-confident and unimpressed by Phoenix, and is addressing the judge directly in the bottom screenshot.
Presumably we’ll find out more at TGS!
