After defeating Sylvia at the Crimson Demon Village, Kazuma and his party look forward to receiving a reward that could mean freedom from the grind of having to fulfill quests. Kazuma himself, however, seems to be having nightmares and bouts of paranoia.

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.

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.

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.

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.

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.
