In addition, badges distributed to staff at Dokudamien can be found about 30 meters away from the scene. Since the first discoverer was a resident of the same facility, the Investigation Division 1 asked the new full-time investigation team for support. Arata Aoyama (Takashi Tsukamoto) and Michitoshi Sakashita (Nozomi Kotaki) will work at a nursing home as an undercover investigator. On the other hand, Yu Amagi (Kiyuki Higashiyama), Yoshiki Ebisawa (Seiichi Tanabe), and Takumi Nonomura (Jin Shirasu) also pursue this case on their own.

However, Michitoshi is not convinced and has doubts about Aoyama's attitude as a detective.
