Synopsis

Ran and Sonoko were preparing for a massive concert by Two-Mix, the immensely popular J-Pop duo. Several hours before the event, Conan and the Detective Boys found themselves in a coffee shop, where they encountered a woman shielded by sunglasses and a cap. This woman, it transpired, was Minami Takayama, the group's singer, possessing a voice remarkably akin to Conan's own.
