Although Takao Nakano's Sexual Parasite: Killer Pussy (Kiseichû: kirâ pusshî) was released on sale DVD in Japan just over a year ago, I'm posting about it here and now for the benefit of those who aren't familiar with it, and are interested in such movies. The sale DVD (DMN-059; NTSC, region 2, no subtitles) can be purchased on-line from Amazon Japan K.K..
There are two official pages (viewer discretion is advised) for Sexual Parasite: Killer Pussy on the website of Total Media Corporation (TMC K.K. / K.K. Tî Emu Shî). Also, there's a page with a downloadable trailer (viewer discretion is advised) for the movie on the J-sploitation subsite of GOMORRAHY.com.
Sexual Parasite: Killer Pussy starred Sachika Uchiyama, Natsumi Mitsu (viewer discretion is advised), Sakurako Kaoru, Tôgo Okumoto, Tomohiro Okada (he was also in (Takao) Nakano's Mikosurihan gekijô: namashibori sûpâ DX and Daisuke Yamanouchi's Uzuku gibo to musume: nekojita kurabe), Toshimichi Tasaki (he was also in Ryûhei Kitamura's Godzilla: Final Wars (Gojira: fainaru wôzu) and the late Teruo Ishii's Japanese Hell (Jigoku)), Kanji Tsuchiya, and Yumi Yoshiyuki (she was also in (Takao) Nakano's Mikosurihan gekijô: namashibori sûpâ DX, his Queen Bee Honey (Bikyonyû kosupure senshi: Kuinbî Hanî), Kenjirô Fujii's Pink Ribbon (Pinku ribon), and Hiroshi Takahashi's Ichi of Sodom (Sodomu no Ichi) - one of the four movies in Euro Space et al.'s Horror Bancho Series (Horâ banchô shirîzu)).
