The franchise's story centers on wizards who gather mazica in order to save the world. Junior high school student Kezuru wakes up after a strange dream featuring himself as a wizard, a creature called "mazin," and a mysterious girl. The next day, his friend Kuracchi proudly shows off the newly launched Mazica Party card game. To Kezuru's shock, all the characters drawn in the game's cards are just like the ones in his dream. Meanwhile, Kezuru receives a notification for an event at the major international company Mazica. Intrigued, Kezuru goes to the Mazica Store as directed, only to meet the Mazica CEO himself, Jeff Johns. Johns says, "I have great expectations for you," and hands Kezuru Mazica Gear. On his way back home, Kezuru is attacked by an airship-like creature. Just when he thinks, "this is it!" to himself, his Mazica Gear erupts and a magic book appears. When he scratches a card, he seals a contract with Barunya, a "mazin" creature that is an odd remixed fusion between an airship and a cat. The mysterious girl Anya says Kezuru and those of his ilk will be "the true wizards who save the world." Amid all these mysterious revelations, Kezuru enrolls in the Mazica Academy and engages in Mazica Party card battles alongside his partner mazin. (Source: ANN)

High school student Haru Yoshioka is bored with the monotony of life. One day, she saves Prince Lune of the Cat Kingdom from being run over by a truck. As a token of gratitude, the Cat King sends her "presents" and invites her to the Cat Kingdom to become Lune's wife. Haru's inability to properly communicate with the cats leads to the misunderstanding that she has accepted the proposal.

As Haru ponders on ways to escape the predicament, a mysterious voice instructs her to search for the Cat Bureau. However, not long after she finally arrives at the bureau, a horde of cats swarms in and forcibly takes her to the Cat Kingdom, along with a member of the Cat Bureau. Concerned for their safety, owner of the Cat Bureau, Baron Humbert von Gikkingen, follows close behind.

The more Haru immerses herself in the activities of the Cat Kingdom, the more cat-like she becomes. To her dismay, she soon learns that, unless she can find her true self, she may become a cat permanently. Haru's adventures in the world of cats lead her down a path to self-discovery, allowing her to return as a more confident person.
