After uncovering Ruby’s true identity, Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi) discover a cache of firearms and drugs. They inform only Special Investigation officer Sahara (Takayuki Kinba) that the incidents were not orchestrated by Kyowakai or the Marugami-kai, urging him to investigate those behind the scenes. Both Himuro and Sahara suspect corruption within the police, with Sahara casting doubt on Matsumiya (Gen Hongo) and others. As police suddenly move to arrest Mita (Shun Sugata), Himuro and Sahara find it suspicious that attention shifts from Kyowakai to the Marugami-kai following Mikawa’s (Yasuhiro Arai) appointment as deputy commissioner. Sahara struggles to investigate Mikawa due to his ties to the powerful Yoshioka family. Meanwhile, suspecting religion is linked to an impending terror plot, Himuro begins reaching out to those connected to the World Kamome Church.
