It's no surprise that the Demon Lord's warriors are terrified of the Crimson Demons, the clan from which Megumin and Yunyun are from. Even if the Demon Lord's generals invade their settlement, the Crimson Demons will easily defeat them because to their ultimate mastery of advanced and overpowering magic. When Yunyun gets a supposedly serious letter warning of a potential tragedy in her hometown, she alerts Kazuma Satou and the rest of his party right away. It turns out to be a hoax by her fellow demon who aspires to be a novelist after a series of bizarre misunderstandings. Nonetheless, Megumin gets concerned about her family and joins the party in their journey to the Crimson Demons' hamlet. Kazuma and the others decide to go sightseeing while they're there.
