Kazuma has crashed Darkness's wedding to Aldarp and pays him the two billion eris he says he's owed. Aqua and Kazuma try to make off with Darkness but Aldarp won't relinquish her so easily and orders his guards to stop their escape.

Darkness departs the mansion leaving behind a note. Not satisfied by a single note, Kazuma, Aqua, and Megumin protest in front of the Dustiness manor but are rudely turned away. Kazuma, frustrated with everything, is approached by Dust who needs his help.

Evading the angry mob, the gang discover that the source of the town's water is being poisoned by the man from earlier, who is revealed to be one of the Devil King's army leaders, Hans the Deadly Poison Slime.

Darkness is back, but not to stay, if Kazuma and her father have anything to say about it.

Darkness's wedding to Aldarp is imminent. Despite Aqua's and Megumin's pleas, Kazuma has no intention of intervening. Vanir then visits the mansion and reveals a shocking secret to Kazuma.

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

As a result of a magic circle that Aqua had drawn in Keele's dungeon, strange explosive doll monsters have started to appear, putting the town at risk.

The Devil King's army attack alarm rings in the royal capital! The adventurer's guild calls on high-level adventurers to join the battle. Having failed to capture the thief at Alderp's mansion, Kazuma joins the fight in order to redeem his reputation.

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.

"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 thinks of a way to stay in the capital for Iris's sake, and declares that he will capture the thief who's causing a stir in the streets! Since the thief targets nobles with bad behavior, Kazuma and his friends decide to stay at Alderp's mansion.

Kazuma and his friends return to Axel and receive 300 million eris as a reward for subjugating Sylvia, an executive of the Devil King's army. Kazuma and Aqua go to high-end restaurants, and Aqua enjoys her long-awaited life as a celebrity.

Gamer Kazuma dies in a freak accident, and is met in the afterlife by a crass goddess, Aqua.

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.

What started as dinner at Darkness's mansion with Princess Iris has turned into Kazuma being dragged back to the castle! Rain explains the situation, and Kazuma agrees to keep Iris company. His wild stories leave the princess with stars in her eyes.

Vanir gives Kazuma the choice of either selling the intellectual rights for his real world products for a one-off payment of 300 million eris, or maintaining a profit-sharing contract of 1 million eris a month.

A low-grade goddess turned arch priest who works hard to acquire party trick skills, a disappointing arch wizard who can only unleash explosion magic once per day, and Kazuma himself, whose only redeeming quality is his good luck. Kazuma despairs over the completely useless party that's been formed.

Darkness, Aqua, and Megumin are back to continue their quest against the Devil King. Kazuma is back too, but the only adventures he has waiting for him exist within the criminal justice system.
