Chisato (Takaishi Akari) and Masahiro (Izawa Ayori) were tested by Natsume Kei (Kusakawa Takuya), the leader of the large-scale project of the Killer Association. They sneaked into the izakaya as temporary workers. The employees of the izakaya were suspected of fraud and money laundering. OnceOnce the evidence is obtained, all executions will be carried out immediately.
