The Kidnapping of a Popular Artist Case (人気アーティスト誘拐事件 Ninki Ātisuto Yūkai Jiken) is the 81st and 82nd episode of Detective Conan anime.

Ran and Sonoko are getting ready to attend a huge concert by the very popular J-Pop band Two-Mix. Some hours before that, Conan and the Detective Boys go to a coffee parlor and meet a lady with sunglasses and a cap, who turns out to be the singer of the group, a woman named Minami Takayama whose voice is rather similar to Conan's.

At some point, however, Takayama gets outta the parlor and is confronted by two mysterious men in a car. She's then forcibly pushed into the backseat of the vehicle, where her partner Shiina Nagano is bound and gagged! The children witness this and notify Megure and Takagi, trying to help as much as they can to rescue the two artists.
