Kindaichi and friends visit an opera house to see a live performance of The Phantom of the Opera. Miyuki and Saki are excited to meet the famous actress Leona Kozuki, who plays the heroine. During the reception for theater members, Himori, who had left the theater company, approaches Leona, but is harshly rejected by Mikitani, a current theater company member. The other company members Izumi and Jo are also on high alert against Leona being scouted by another company. Eventually, rehearsal begins, and Izumi takes center stage under Director Kageshima's instruction. However, the very next moment, the chandelier falls down, taking Izumi's life. Shiragami, a journalist, claims that it was no accident, but the work of the Phantom who lurks within the opera house. The Phantom's shadow appears before Leona and Inspector Kenmochi, and further tragedy ensues. Kindaichi then learns about Kiryu, a prodigy actor who played the Phantom on that same stage three years ago.
