Ghost Tears.Togusa investigates the death of Detective Naoharu Mizuki, killed by an explosion at a dam while holding a suitcase containing prosthetic legs from the Mermaid's Leg corporation.[14] Togusa questions Dr. Zhinzhee Bekka Arr Thied, head of a Kuzan water company owning the dam, and also a Qhardi, but is told to back off. Meanwhile Major Kusanagi's team of Batou, Ishikawa, Borma, Paz and Saito is called out to stop a Qhardi separatist organization. When they catch them, Kusanagi is intrigued by their contaminated ghosts. Aramaki says they are dealing with a false memory virus that can infiltrate, hack, and brainwash simultaneously created by a programmer known as "Fire Starter", leader of the Qaurdi separatists in Kuzan. The captured separatists all have Scylla (スクラス, Sukurasu) tattoos.[15] Meanwhile, Kusanagi gets closer to her prosthetics specialist boyfriend Akira Hose, but Togusa confronts Kusanagi about him, suggesting a link between Akira, the dam explosion, prosthetics-related crimes and his involvement with her. Kusanagi eventually realizes that Akira is the key, but also a puppet in a complex web involving Japanese weapons manufacturer Harimadara Heavy Industries, weapons smuggling, explosive prosthetics and propagation of the false memory virus. When she finally confronts Akira, he takes his own life, terminating himself as a virus host. Batou later tells Kusanagi that he figured she was the original Scylla and leader of the separatist army, but she replies that she's stopped switching bodies so often since then. Later Kusanagi asks Togusa to join her team, even if he is just a natural, married, and a father.
