Yes, this is supposed to be a female Michael Knight. And no, KITT's still a guy.
I'm writing a Knight Rider/Hyperdimension Neptunia crossover AU called Knight Rider Re;Birth. Michelle and KITT go around Gamindustri solving problems that are too big for your average guild quest, but too small to get the CPUs involved. Kei plays the role of Devon Miles, because Michelle and KITT work for Lastation in particular (Lastation built KITT, and Michelle is a Noire worshipper).
The last picture, which is just a repeat of the first picture except with a purple tint, is a reference to the intro sequence to Knight Rider, where half of the intro is tinted purple to give you the impression that it's dusk.
