A flashback tells how Chinatsu meet Shishio. She was a survivor of the Shishio’s killing spree at an opera and he was impressed when she shot him. Back in the present, Koko's bodyguards continue to protect Koko and Jonah when Orchestra performs a driveby using an M2 heavy machine gun in their pick-up truck. The team manages to destroy the truck, forcing Chinatsu and Shishio out into the open, where Lutz snipes down Shishio 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, but 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, Chinatsu is caught by Koko infiltrating into their hotel with Lehm aiming his sniper rifle on her. As they both answer each others questions, Koko offers Chinatsu to join her team but she refuse and tries to kill her only to be shot to death by Lehm. 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. (Source: Wikipedia)
