@Sypha: I can tell you with complete certainty that the girl after the Kasumi pics is none other than Aska from the Super NES version of Teenage Mutant Ninja Turtles: Tournament Fighters (a.k.a. Teenage Mutant Ninja Turtles: Mutant Warriors, as it was known as in Japan). The two girls in the kimono and the maid outfit respectively are lost on me. Fantastic CG set by the way. I hope you're able to get and post that recent one by Arikawa that has Shaia Hishizaki from Voltage Fighter Gowcaizer in it in the near future.
EDIT/ADD: I would like to add that I am SERIOUSLY glad to see some hentai of Racheal from Martial Champion based off her ending from that game.
@Sypha Arikawa loves obscure characters. I only recognize Taki, Rachel, Kasumi, Kunimitsu and Ibuki. Thanks Uploader and the guys who also managed to get all the girls names.
