Episode 5

A shocking truth came to light—one that even Kanzaki himself had not known. Yet, Sano resolved to trust Kanzaki and continue working alongside him; following a message left by Kaoru, the two headed to a specific facility. There, testimonies from Mamiya (Takashi Yamanaka) and Ashida (Osamu Kao) revealed the true purpose of "ALIUS LAB" and the reason Kaoru had left Sano. Eventually, Sano and Kanzaki closed in on the culprit's identity—but the killer's gun was already aimed at their target from behind.
