The rookie competition is one of the most highly anticipated spectacles of the Nine School Competition and a chance for freshman athletes to shine. First High's beloved Miyuki Shiba takes center stage during these matches to give a beautifully elegant performance. Her brother, Tatsuya, doesn't have a moment to waste as he works around the clock as part of the engineering team, relaxing only when he gets a chance to admire his sister from behind the scenes. But after his teammates fall prey to a horrific accident, Tatsuya is suddenly thrust into the spotlight and set on a direct collision course with the Crimson Price, Masaki Ichijou!

It's time for the National Thesis Competition to take place in Yokohama but what was supposed to be a grand event for the participating students has been turned into a battlefield. A mysterious band of armed magicians and mechanized weapons have stormed in and it may be up to Tatsuya and the others to get everyone home safely!

Looking at Miyuki and Tatsuya now, it might be hard to imagine them as anything other than loving siblings. But it wasn't always this way... Three years ago, Miyuki was always uncomfortable around her older brother. The rest of their family treated him no better than a lowly servant, even though he was the perfect Guardian, watching over Miyuki while she lived a normal middle school life. But what really bothered her was that he never showed any emotions or thoughts of his own. However, when danger comes calling during a fateful trip to Okinawa, their relationship as brother and sister will change forever...

July 2096. Another year means another summer, and that means a new Nine School Competition. Just to spice things up, the participants are informed only weeks before the event that there are some massive rule changes! While everyone’s running around frantically trying to figure out what they should do, Tatsuya catches wind of another plot that might be brewing behind the scenes of this year’s competition. As the shadows rise for the second year in a row...let the games begin!

The year is 2095. Magic has been tamed as another form of technology, and the practice of magic is now a rigorous discipline. Brother and sister Tatsuya and Miyuki Shiba are just about to start their first year at the renowned First Magic High School of Japan. But the school's ironclad rules mean that the brilliant Miyuki enters the prestigious Course 1, while her older brother, Tatsuya, is relegated to Course 2--and that's just the beginning of their troubles!

Spring is here, and the graduating seniors of First High are planning a getaway to sunny Okinawa. At the same time, Tatsuya and Miyuki will be on the island as the Yotsuba family’s representatives at a memorial service for the victims of the invasion there several years earlier. Of course, this is just a cover for their true purpose: foiling a terrorist plot hatched by some deserters and Australian operatives. Their primary target is a party that Shizuku and Honoka will be attending—What are the chances? Romance is in the air, and danger is on the horizon, making this a vacation they’ll never forget!

After the conclusion of the Nine School Competition, summer arrives in force, bringing with it that most precious salvation for students--vacation! Shizuku invites Tatsuya, Miyuki, and their friends to her family's island villa for a bit of fun in the sun, but all of this is just a pretext to set the perfect tropical stage for Honoka's romance. Meanwhile, the ace of Third High, Masaki, entertains Kichijouji at home, unaware of his partner's struggle with self-doubt. Shun finds himself playing bodyguard to a beautiful foreigner, and Eimi is cornered for a secret she can't reveal at any cost. The one who's got it toughest, though, is Mayumi, who's desperate to find the next student council president before time runs out!

Late April 2097—the use of strategic-class spells doesn’t stop with the Brazilian military, as the Great Asian Alliance deploy Thunderclap Tower in the Gulf of Guinea. Magic fans the flames of war, which soon engulf the entire world. As public opinion inevitably turns against magicians as a whole, Edward Clark, a researcher of the USNA, proposes an expansive space development endeavor called the Dione Project to promote the peaceful use of magic. Taurus Silver’s name appears on the list of chosen candidates, which leads to people uncovering the truth—that this is in fact Tatsuya, throwing him and Miyuki into yet another trial.
