In Dubai, Koko has Tojo teaching Jonah school lessons while she goes out shopping with Valmet. However, the assassin group Orchestra, compose of a teenage girl named Chinatsu and her mentor Shishio (Master), are hired to assassinate Koko. Koko and Valmet are saved by Jonah from Orchestra after he skips Tojo's lessons. As a gunfight ensues in downtown Dubai, Jonah and Valmet protect Koko from Orchestra while the latter easily kills Dubai Police Force officers responding to the shootout. Valmet is shot in the leg, which Jonah responds by rushing to kill Shishio to allow her and Koko to escape. However, Jonah is dragged by Lehm using a hook and rope where he chastises the boy for needlessly sacrificing his life. Lehm has Jonah escape with Koko while he holds off Orchestra. Orchestra soon run out of ammo and retreat to their pick-up truck armed with a machine gun. Lehm concludes Chinatsu has great observations skills and is able to control the wild Shishio while he and Valmet rendezvous with the rest of the team and try to separate the duo before they reach Koko. Meanwhile, Jonah tells Koko how he feels guns make people into monsters which she appreciates him for opening up.

Koko ist nicht überrascht, ihren Namen auf der „Zu erledigen"-Liste zahlreicher Auftragskiller zu finden - unter ihnen das berüchtigte Team „Orchestra".

Natürlich werden die beiden ausgerechnet jetzt von den Killern gestellt und unter Beschuss genommen.
