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!

The nationwide All-High Magic Thesis Competition is lauded as a more cerebral and refined contest than the action-packed Nine School Competition. After seeing more than enough gunfights and magical duels in between classes, this change of pace suits Tatsuya just fine. Unfortunately, not every spectator is content with simply enjoying the event. With rival students, intelligence operatives, and a foreign assassin all in attendance, Tatsuya might need more than just his wits to keep everyone safe!

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!

April 2096 has arrived. Despite the commotion they were involved in, Tatsuya and Miyuki safely passed all of their classes and are now returning as juniors for another semester. In light of Tatsuya’s accomplishments, a magic engineering curriculum has been established, granting him a new lease on proper student life. With his new classes and his position as acting student council vice president, Tatsuya is certain that this year for sure, he’ll be able to enjoy a peaceful time at school with his sister...until three freshmen form the elite Numbered families start raising hell in their First High debut!

December, 2095. In exchange for Shizuku going to study in the USNA, Lina has been attending Magic High School in Japan. Tatsuya figured out her true identity as a member of USNA special forces right away but as soon as one mystery is solved, another breaks out. Right around the same time as Lina's arrival in Japan, there has been a series of attacks on magicians by something called the "vampire." But while Tatsuya and Mikhiko try to use old magic to discover the identity of this criminal, an assault on their school occurs!

Miyuki's classmate Shizuku Kitayama is on her way to study abroad. For magicians, this is normally impossible, since allowing the genes of someone who can use magic outside their home country's borders is tantamount to giving up national secrets. But it's allowed to happen in one case-exchange programs. And that's how Angelina has arrived in Japan from the USNA to study at First High. But it seems she's a part of something much bigger than a simple cultural exchange!

At the same that the leader of the USNA's elite magician unit, the Stars, traveled to Japan under the identity of an exchange student named Lina, the parasite incident wreaked havoc on the First Magic High School until Tatsuya and his friends saved the day and brought the incident to a peaceful conclusion. However, the parasite merely lost its first host and continues to wander this world. More importantly, it's found its next host-a humanoid helper robot. After copying Honoka Mitsui's behavior and patterns, the parasite has been reborn as Pixie, vowing to follow and serve Tatsuya. After learning more about parasites from Pixie, Tatsuya gathers Miyuki and the others to head towards the Aoyama Cemetery to fight against a new impending danger!
