Momo Kasuga is pretty much on ass shaking duty only in what I have seen of Super Sexy Heroine Dirty Gemini so far.
Super Sexy Heroine Dirty Gemini (from what bit I have been able to see) is clearly a Dirty Pair knock off with Asami Sugiura as the Kei and Momo Kasuga as the Yuri. I have only been able to see the first ten minutes in poor video quality. Seems to be typical bikini action fare from our Pacific friends. No idea who the bad guy is supposed to be, but he wears camouflage and a Dracula cape, so… I got nothing.
According to the Anime World Order podcast, The Dirty Pair was inspired by female wrestling team The Beauty Pair. Who knew?
