Tomon Makoto (played by Naoto Fujiki) launched an action to prove the innocence of Hiroka Oto (played by Yasuko Matsuyuki), the suspect in the arson murder case developed by the KMT police, and finally found out that it was the work of the former KMT police researcher Shimogaki Manyou (played by Taro Nakajima).However, when the police broke into Xiayuan's residence, he found that he was dead, leaving a note of “H Tumen ” next to his body.
Immediately afterwards, Tommun received a call from Takashi Ichimoto (played by Keiro Horibe), who planned a series of events.Ice Room said: “Science will not lie... Do you still believe in this kind of fantasy?”Tumen realized that his real goal was not Odou but himself.
According to Tomaru Yuto (Nakazawa Motoki), Shimogaki's death was caused by poisoning.But that poison is probably an unknown compound, and Shigaki should not have the technology to make this poison.
In addition, the illegal access of the server of the Tech Police Research Institute also uses a high degree of technology, and the image of a prisoner who is good at science and IT has surfaced.
The next day, Tom and Odo university classmate Harada Toshigo (Yukana Yoshihiko), came to the appraisal center.
Tumen commissioned Harada, who is also an IT security expert, to lock down the person who invaded the server.Tumen began to identify the poisons ingested by Shigao, while Harada began to analyze the illegal deposit and withdrawal.
