While wandering through Wiz's enchanted shop alongside his companions, Kazuma Satou discovers a mystical wish‑granting choker and chooses to wear it. Only then does Wiz reveal that the necklace will crush its wearer after four days unless their longing is satisfied. This would pose a danger if Kazuma were unaware of his own wish. Worried for his safety to protect him from danger, Aqua, Megumin, and Lalatina Ford 'Darkness' Dustiness consent to carry out his requests in order to fulfill his desires and ultimately grant whatever he asks.
