Musica ex Machina phase.2.A flashback reveals that Chinatsu was a survivor of a killing spree at an opera caused by Maestro, who was impressed when she shot him from behind. Back in the present, Koko's bodyguards continue to protect Koko and Jonah when Orchestra performs a drive-by using the M2 Browning machine gun in their pickup truck. The team manages to destroy the truck, forcing Chinatsu and Maestro out into the open, where Lutz snipes down Maestro after he refuses to heed Chinatsu’s warning. Chinatsu vows revenge against Koko before she escapes. Meanwhile, a CIA agent named Scarecrow, who has been hunting down Koko for weapons dealing, tries to have her arrested and deported, but due to her father’s connections, the Dubai Police Force instead releases Koko and covers up the shootout. The chief of police tells Koko that she and her team are to be confined to their hotel for the time being. As she and Jonah return to their hotel, they have an in-depth discussion about arms dealing. Three days later, Koko catches Chinatsu trying to infiltrate into the hotel. During their conversation, Koko offers Chinatsu to join her team, but Chinatsu refuses and tries to kill Koko. However, Chinatsu is shot to death by Lehm with his sniper rifle from a distance. As Koko closes the eyes of the dead girl, Koko calls the chief of police to cover up Chinatsu’s death, while a hidden Jonah is listening.
