As tensions escalate between the Tokyo Alliance and the Chinami-gumi, Eiko is assigned to protect a key figure who knows Masaya. Her path crosses with Graniso—who is hunting this same individual as an assassination target—while the maneuvers of the Chinami-gumi's Kai (Naohito Fujiki) and the Chinese mafia boss Yin-Li (Ryo) further heighten the tension. Meanwhile, Gojo (Kengo Kora) of the Shinjuku Police Organized Crime Division approaches Eiko, drawing her into a web of internal police friction and conflicting agendas, leaving her increasingly isolated.

With multiple organizations entangled, the situation grows increasingly complex. Amidst the conflict surrounding a key figure, the moment of confrontation between Eiko and Graniso finally draws near. Meanwhile, ominous signs emerge regarding Kawakami's movements, blurring the lines between friend and foe. The conflict reaches an unexpected conclusion, and a new phase begins as the truth revealed by the key figure causes everything to fall into place.

Eiko's investigation into the truth behind Masaya's death begins to falter as suspicion and betrayal spread. The relationships and information she once trusted start to unravel, and the truth slips further into the shadows. Amidst the clash of conflicting agendas between the police and the underworld, Eiko is forced to make a choice that challenges her own convictions—and the situation takes an unpredictable turn.
