The story of the franchise centers on sorcerers who collect mazica to protect the planet. Junior high student Kezuru awakens after a bizarre dream in which he is a wizard, encounters a creature called "mazin," and meets a mysterious girl. The next day his friend Kuracchi proudly shows off the newly released Mazica Party card game, and Kezuru is stunned to find that every character on the cards looks just like those from his dream.
Soon after, Kezuru receives a notification for an event at the global company Mazica. Curious, he follows the directions to the Mazica Store and meets the CEO himself, Jeff Johns. Johns says, "I have great expectations for you," and hands Kezuru a piece of Mazica Gear.
On his way home, Kezuru is attacked by an airship‑like creature. Just when he thinks the fight is over, his Mazica Gear explodes and a magic book appears. When he taps a card, he seals a pact with Barunya—a "mazin" that is an odd hybrid of an airship and a cat.
The mysterious girl Anya tells Kezuru that he and others like him will be "the true wizards who save the world." Amid these bewildering revelations, Kezuru enrolls in Mazica Academy and participates in Mazica Party card battles with his partner mazin.
