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.
