Domoto Kazuki is a famous pianist. Two years ago, he suddenly announced that he would no longer play the piano and turned to the organ. He also spent money to build the Domoto Concert Hall and planned to hold a concert on the day of its completion. However, before the concert, students of the Domoto Conservatory of Music died one after another, first in an explosion and then in a single murder. Sonoko brought Conan and his party to listen to the rehearsal and met the soprano singer Reiko Akiba. Akiba, who had absolute pitch, also began to encounter danger: Runsheng Tea was drugged, he was attacked by an air gun while taking a forest bath, and was knocked unconscious on the day of the audition. However, it was from these events that Conan found the logic of reasoning: the murderer tried to exclude Akiba from the murder. The concert that had already officially started here was unaware that there were explosions outside the music hall. Xiaolan, Huiyuan Ai and more than a thousand people in the concert hall were suddenly in danger, and absolute pitch became the only life-saving clue. Conan found the logic of the explosion and had to find the criminal before he detonated the last bomb.
