Tetsuo and Kyoichi work together to trace Nobuto's footsteps before his disappearance. But in that process, they're given a violent and possibly fatal ultimatum by the organization.

Tetsuo and Kasen work with their old college friend to make it look like Nobuto is still alive. While trying to find out Nobuto's password to access his social media account, Tetsuo encounters Nobuto's father.

Tetsuo races against the clock to plant evidence to frame someone else as Nobuto's murderer. Kasen scrambles to keep Reika away from Kyoichi after he tries to get in contact with her.
