Conan, Ran, Mouri, and Sonoko travel to Shikoku to see the kabuki play Phantom of the Konpira. It is a play based on Phantom of the Opera. Things start to mimic the play. There are requests for a heroine change, sightings of a phantom, and a deliberate attempt on the heroine, just like Phantom of the Opera. The chief of the stage setting is killed, and the chairman and the sponsor are arrested by circumstantial evidence. Conan uses Sonoko to reveal that heroine tried to ruin the theater's play.
