In a futuristic Tokyo, a group of policewomen are battling a monster. One of them, Katsumi Liqueur, recalls encountering it before... Katsumi Liqueur, an American of Japanese heritage, travels to Tokyo to visit her ailing mother, Fuyuka, in the hospital. After her taxi is delayed by traffic, she takes a shortcut through an alley, where she stumbles upon a monster and two policewomen fighting it. Later, she meets their leader, Rally Cheyenne, who appears to have been anticipating her arrival, even though Katsumi has never met her. The policewomen seek Katsumi's assistance in confronting the monster, but she, reluctant to accept the existence of magic, refuses.
