The 9th volume of the light novel features an untold episode occurring at Wiz's store where Yunyun, Megumin's supposed rival, encounters the gang. Kazuma is unsettled by the chaos and stumbles upon a choker that he nonchalantly puts on. However, he is unaware that the choker possesses a spell that grants his deepest wishes through strangulation. The group frantically attempts to fulfill his desires while deliberating the ramifications of a deadly outcome. Wiz provides her lap as a cushion, Darkness exercises her chest with push-ups, and Megumin and Yunyun participate in an exposed game of rock-paper-scissors while Aqua completes several tasks. Nevertheless, it remains to be seen if their collective efforts will be sufficient to rid Kazuma of the lethal stranglehold of the choker.
