With their members being perfectly suited for the job, Kazuma's party, along with Wiz, are chosen to lead an attack against the Destroyer. Meanwhile, Darkness tells Kazuma that her true name is Dustiness Ford Lalatina, the daughter of a well-regarded family. Using Aqua's barrier breaking spells and Megumin and Wiz's explosion magic, the party manage to take down the Destroyer, only to set off a self-destruct sequence. Heading inside to find a way to stop the Destroyer from exploding, Kazuma manages to find the power source and has Wiz teleport it elsewhere, before Megumin uses a powered-up explosion to destroy the fortress. As peace returns to the town, Kazuma finds himself under arrest as the power source he teleported away ends up destroying a noble's mansion.
