Somewhere in a desert region, a two-person hitman team finishes off a mafia turncoat before heading to their next assignment.
In Dubai, Koko and her crew are resting in a fancy hotel while they try (and fail) to teach Jonah some basic math skills. Koko also talks about the previously-hinted duet of hitmen calling themselves the "Orchestra," previously a six-man crew who was all but wiped out in a shootout with police where they emptied nearly 20,000 rounds of ammunition in one firefight.
Valmet then pops up to take Koko out on a date around town, and Koko accepts. Jonah soon sneaks out of the room and follows them, but so do the assassins on the streets of Dubai. While Valmet decides to buy a watch that Koko has her eye on, the Orchestra assassin Chinatsu and her teacher open fire, beginning a prolonged firefight with Valmet, Koko, Jonah on one side, and Orchestra on the other.
Police soon get involved, but Chinatsu destroys them with her grenade launcher. Then the rest of Koko's team arrives as reinforcements. Orchestra retreats, preparing to get a .50 cal machinegun and retaliate as Koko and her team prepare their next moves.
