Kazuma and his party are down on their luck; Megumin's use of explosion magic backfires and they lose all the bounty from their latest quest. The group sits in shame at the adventurer's guild until Yunyun arrives. She tells Kazuma that she needs to have a son with him to save the world and that the Crimson Demon village where she and Megumin are from is under attack by one of the demon king's generals. Later, at Kazuma's mansion, the former part of the story is found to be a falsity written by Megumin and Yunyun's classmate, Arue. Embarrassed, Yunyun heads back to the village.
