After meeting Karina Komiya face-to-face, Arata senses something unfathomable from her, but can’t find a clue to the case. Then Lee Aki, the secretary of her opponent, Kosuke "Heracles" Yakushiji, is murdered. Unit One decides to split up to investigate both the attackers and their victims, but…

Through a Mental Trace, Arata discovers that the supposedly-dead Kurisu is alive and uncovers the truth behind the terrorist bombings. Shimotsuki, meanwhile, has launched a forced search of Heaven’s Leap and brought Unit Two to locate Kei. Torri, cornered, takes Maiko hostage and confronts Kei, but Maiko takes advantage of a momentary opening to end his life.
