A winter night when they were eight years old. Childhood friends Sho Hoshirube and Rou Koyanagi were taken away by nameless adults. At the moment of parting that day, the three made a promise.

"Someday, let's all three of us become Grand Mages and see all the different worlds we've never seen before."

You still remember that promise. The childhood friends you were separated from became Grand Mages at the young age of ten, and are now hailed as "once-in-a-millennium geniuses." Every time you hear of their exploits in the newspapers or on the Magic Bureau radio, you feel a sense of inferiority, yet your heart warms.

Now, in the hallway of the Philestore Magic Academy. Looking out, you can see the faint silhouette of the Magic Tower sitting deep within the Great Forest. Every time you step into this hallway, you are reminded that your two childhood friends, now world-renowned Grand Mages, are right there. As you stare blankly at the shadow, the bell rings to announce the next class.
