In a special episode bundled with the 9th volume of the light novel, the gang stumbles upon Megumin's self-proclaimed rival, Yunyun, during a visit to Wiz's store. When Kazuma inadvertently triggers a magical choker that grants wishes but tightens around his neck until his desire is fulfilled, chaos ensues. To save Kazuma from a deadly fate, the group goes to great lengths to fulfill his whims: Wiz offers her thighs as pillows, Darkness showcases her chest with push-ups, and Megumin and Yunyun engage in a high-stakes game of strip rock paper scissors, while Aqua handles mundane tasks. Will their unconventional efforts be enough to break the choker's deadly grip?
