Kindaichi Shounen no Jikenbo

Hajime Kindaichi's unorganized appearance and lax nature may give the impression of an average high school student, but a book should never be judged by its cover. Hajime is the grandson of the man who was once Japan's greatest detective, and he is also a remarkable sleuth himself. With the help of his best friend, Miyuki Nanase, and the peculiar inspector Isamu Kenmochi, Hajime travels to remote islands, ominous towns, abysmal seas, and other hostile environments. His life's mission is to uncover the truth behind some of the most cunning, grueling, and disturbing mysteries the world has ever faced. Invited for a anniversary celebration, Kindaichi, Miyuki and inspector Kenmochi re-visit the Opera House. There they discover that a play of "The Phantom of the Opera" is being rehearsed again. However, it doesn't take long when members of the acting troupe are killed by the "Phantom". Kindaichi will once again have to solve a murder series in the Opera House.
