The party runs into Megumin's self-proclaimed rival, Yunyun, during a trip to Wiz's shop. Kazuma then notices a choker at his feet and casually tries it on. It's a magical choker designed to make wishes come true and it will continue to tighten around the wearer's neck until that happens. The others work hard to make Kazuma's "dreams" come true, but will it be enough to free him from the choker?
