As Chikara Nakagoshi (Jun Matsumoto), Akari (Aya Ueto) and Yoriko Michio (Nanako Matsushima) gathers, the landlord Yuzuru Hoshi (Kazuyuki Asano) appears and tells them a shocking information. Information talking about the location of the serial child killer suspect, Boy A is circulating social media—And the location mentioned seems to be the apartment Chikara and the others are living at judging from the attached photo. Hoshi whispers that he believes Room 601’s resident, Kamijoh (Hiroya Shimizu) is Boy A.
Chikara is asked by the landlord, as the leader of the apartment, to go meet Kamijoh. Unable to think of a good way to approach him, a few days pass when one day he ends up being alone with Kamijoh! Tentatively, Chikara asks about the truth of the rumor that Kamijoh used to be in a juvenile hall to which Kamijoh replies that rumor is true!
