The franchise's narrative focuses on wizards who collect mazica to save the world. Junior high school student Kezuru awakens from a peculiar dream in which he appears as a wizard, alongside a creature known as a "mazin" and a mysterious girl. The following day, his friend Kuracchi proudly displays the newly released Mazica Party card game. To Kezuru's astonishment, every character illustrated on the game's cards mirrors those from his dream. Meanwhile, Kezuru receives a notification regarding an event hosted by the major international corporation Mazica. Intrigued, he proceeds to the Mazica Store as instructed, where he unexpectedly encounters the company's CEO, Jeff Johns. Johns states, "I have great expectations for you," and hands Kezuru a Mazica Gear. On his way home, Kezuru is attacked by a creature resembling an airship. Just as he thinks to himself, "this is it!", his Mazica Gear activates, causing a magic book to appear. By scratching a card, he forms a contract with Barunya, a "mazin" creature that is an odd hybrid fusion of an airship and a cat. The mysterious girl Anya declares that Kezuru and others like him will be "the true wizards who save the world." Amidst these enigmatic revelations, Kezuru enrolls in Mazica Academy and participates in Mazica Party card battles alongside his partner mazin.
