Miyuki, also referred to as Myu-Myu, is a minor character in the live-action film adaptation of Ichi the Killer. She works as a prostitute and is connected to Ryu Long, a Zainichi Chinese gangster and member of the cleaning crew led by Jijii. Miyuki is deeply devoted to Ryu Long, who also functions as her pimp, and she longs for his affection and approval. She is self-conscious about certain aspects of her physical appearance. In the story, Miyuki acts as a link between the underworld figures involved in the conflict. She is later tracked down by the twin detectives Jiro and Saburo, who are working for Kakihara, and the information she provides or helps uncover contributes to the escalating violence and pursuit of Ichi. Her loyalty to Ryu Long places her within the orbit of Jijii's manipulations, but she remains a relatively passive figure whose primary motivation is her personal attachment to her boss rather than any larger agenda. Her role underscores the exploitative and transactional nature of the world the characters inhabit, and she does not undergo significant development or display any notable combat or special abilities.
