The body of a classmate without a left arm was found on the rooftop. As the students panicked, Akane (Ioki Mao) found Kurokawa (Yamamura Ryuta) with a cold expression on his face on the other side of the crowd. In response to the incident, the students were forced to go home, but Akane went to the rooftop after the scene investigation was completed. Then, Eto (Higuchi Kohei) and others arrived and accused Akane of being the culprit. The motive was that the victim, who had recently become interested in Akane and was sniffing around her, had become a nuisance. However, Akane burst out laughing at such a naive idea. However, it seems that Kajitani (Takeda Rina) of the First Investigation Division also considered Akane to be one of the possible suspects, and Akane was questioned.

Meanwhile, Akane visits the Shinozaki family with Yohara (Mizuno Kyoshin) at the request of Shinozaki's (Yoshina Riru) father, Hirohiro (Kagaya Kei), who wants to talk to his daughter's classmates. However, while Hirohiro is crying over his daughter's sudden death, he also seems to be trying to extract some information from Akane and the others.
