Around 1975, mangaka "Monkey Punch" (Katou Kazuhiko) introduced two women, June (left) and Naomi (right), who work as a radio DJ team by day, and by night as... elite counter-terrorism agents! They go by the codename Shamu Neko <Siamese Cats> and had a brief spate of manga adventures eight years after Monkey Punch began publishing the series he is best and internationally known for -- Lupin III. Presently (July 2003), you can still catch a presentation of portions of Shamu Neko as an e-comic at his site.

During 2000, Monkey Punch supervised the animation of one of June and Naomi's stories as Shamu Neko: First Mission, which was released in theaters in the spring of 2001. A poster for the film is shown above. The seiyuu are Hayashibara Megumi (June) and Koyama Mami (Naomi).
