Kindaichi Shounen no Jikenbo

Synopsis

Inspector Isamu Kenmochi is assigned to investigate Sakuragi's death and Hajime explains what they saw. Yuichiro Matoba, the physics teacher suspects the culprit is a former teacher referred to as "M" who was rumored to conduct strange rituals. Student writer Makoto Makabe proposes a plausible theory of how the murder was carried out, but Hajime believes there is a different scenario. Kenmochi tells Hajime how 10 years earlier, the Mystery Club member, Chihiro Aoyama, was investigating the seven mysteries but she suddenly disappeared. Meanwhile, student Takahiro Onoue has Sakuragi's data disc which contains a message about who the culprit may be, but as he decodes it, he is beaten to death with a wrapped up hammer by the "Magician" and his body is dragged to the printing room to coincide with one of the seven mysteries. When Hajime and his friend Miyuki Nanase read the Mystery Club's minutes, they find a copy of Sakuragi's notes inside, also stating that there were originally only six mysteries. Miyuki is attacked when she tries to remove a poster of Makabe on the wall in the old building of Fudo High School. Hajime then finds Miyuki badly injured beside the fountain in accordance with the third mystery.
