Louis Theroux's Forbidden America (2022)

All of the weak monsters have gone into hiding since a leader of the devil king's army has settled in near town. Kazuma, who had been focusing on improving his skills, is stuck at a standstill. With nothing else to do, Kazuma tags along with Megumin's training, which consists of unleashing explosion magic into an abandoned castle.

With debt looming over her, Aqua convinces Kazuma to accept a high difficulty quest to purify a lake, which doesn't require killing any monsters.

Dullahan, a top leader in the Devil King's army, yet again appears at the city in a frenzied rage.

"I want money." After paying back the debt Aqua has racked up, Kazuma and Aqua's monetary situation grows even more dire. The party accepts a quest to kill helpless Snow Sprites and heads for the snowy mountains in order to escape from the stables during this winter so cold it freezes Kazuma's eyelashes solid.

Kazuma and Aqua can't properly accept rewards from quests due to their mediocre party lineup, and are so destitute that even keeping wood on the fire is difficult. Kazuma comes up with a plan and visits a magical accessories shop run by a woman called Wiz.

Kazuma runs into some adventurers he knows while out for a walk and decides to go with them to a shop run by succubi said to show its customers enticing dreams.

The rampaging ancient weapon: the mobile fortress, Destroyer, is headed straight for Kazuma and party's city!
