3

Kenmochi tells Hajime that the old school building was formerly the property of Takahata Pharmaceuticals and that six of their experimental subjects died there. Later, Miyuki wakes up in the hospital after being attacked by the killer and encourages Hajime to continue his investigation despite the risks. He decodes Sakuragi’s code and then finds the body of Chihiro Aoyama hidden in a wall cavity. Hajime calls everybody to the old school building and explains how the killer used a mirror to create the mystery of Sakuragi's murder. He then accuses physics teacher Yuichiro Matoba of the murders and being the "After-School Magician". He was left behind by the Takahata company to keep the six bodies hidden for 30 years and was responsible for the accidental death of Chihiro Aoyama 10 years earlier after she found out about the deaths of the experimental subjects. Suddenly, security officer Ryozo Tachibana rushes forward and stabs and kills Matoba with scissors in revenge for the death of Chihiro whom he reveals was his daughter. Afterwards the police find the six bodies of the experimental subjects and the building is demolished on schedule. A funeral is also held for Chihiro Aoyama that Hajime attends and meets her for the first and last time. (Source: Wikipedia)
