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!

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!

Miyuki heads to the Nine School Battle, but there's trouble waiting for her--trouble in the form of Third High School's Airi Isshiki. The competition is fierce enough already--what does Airi want besides victory? Family politics and magical intrigue abound as the Nine School Battle arc begins!

USNA Major Angie Sirius's arrival in Japan as Lina the American exchange student was suspiciously coincident with the vampire attacks occurring in the vicinity of Magic High School. With the parasites behind the uproar finally neutralized, things have mostly settled down. However, since they merely vacated the bodies they were inhabiting, it's only a matter of time before the parasites find new hosts. As soon as Tatsuya learns the vampiric creatures are still on the loose, he rejoins his friends on the hunt to eliminate the monsters once and for all-even if Major Sirius hounds him in the process!

The Nine School Battle. Ever year in mid-July, students from magic high schools all over the country gather to participate in fierce competitions of magical skill. Miyuki Shiba is among the members of the team First High will send to the battle. The magical skill of the competitors will be a huge factor, but there's another one-the tuning of their CADs. Luckily, they've got someone with them who specializes in the field-Miyuki's older brother Tatsuya. But when the Nine School Battle is targeted by a sinister group, all the talent in the world may not be enough to secure victory...

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!
