It's March of 2097 when Synchroliner Fusion is deployed in South America, and the worldwide upheaval that rose up in its wake has finally reached Japan. The following month, Tatsuya and Miyuki receive a message from the head of the Juumonji clan, Katsuto. They are both formally invited to a conference of the Eighteen Support Clans over rising hostilities directed at the group, ensuring yet more trouble in Tatsuya's future.
The Ten Master Clans and the Eighteen Support Clans have gathered for a conference to raise concerns about Tatsuya's behavior. His official position is that all his actions were necessary to protect Miyuki and he has the full support of the Yotsuba, including the current head of the clan, Maya. Naturally, some of the other families are not so easily convinced. And while this captures everyone's attention, Mitsuya Shiina vanishes without a trace, kicking off yet another incident that may affect more than just First High...
Spring is here and the graduating students are planning a trip to sunny Okinawa. Shizuku and Honoka have invited Miyuki and Tatsuya to a party that sounds like the perfect opportunity to relax for once. It sadly won't be all fun and games because the siblings have also been tasked with stopping a terrorist plot while they're in the south islands. What are the chances? Romance is in the air and danger is on the horizon-this is sure to be a vacation to remember!
Gu Jie, a magician who orchestrated a sinister suicide bombing by manipulating corpses to do his bidding, has gone into hiding somewhere in Japan. As public outcry against magicians builds and humanist forces gain momentum, the Ten Master Clans task Tatsuya, Katsuto, Mayumi, and Masaki to determine the whereabouts of the mastermind behind the bombings. But when Major Benjamin Canopus, the second in command of the most powerful magic unit in the United States, starts gunning for Gu Jie as well, Tatsuya grows inexplicably enraged!
A suicide bombing brings the Master Clans Council to an abrupt close! Armed with only the knowledge that the explosion was triggered by corpse manipulation magic, Tatsuya sets off in search of the perpetrator along with Juumonji. After being egged on by his father, Masaki trails behind them to Tokyo in an attempt to one-up Tatsuya's investigation. But things take a turn for the unexpected when Masaki summons up the courage to propose to Miyuki...
Every year the Yotsuba Clan gathers it's most influential and powerful members. And like always, Miyuki has gotten an invitation. There's only one big difference this time: direct orders from the Yotsuba matriarch requesting her presence on New Year's Day and a bargain that may repeal Tatsuya's status as a pariah if Miyuki is willing to do whatever it takes...
As soon as Tatusya and Miyuki's engagement has been made public, there are already people lining up to raise an objection, starting with the Ichijou Family. And of course, they have a counteroffer-for Miyuki to marry their scion Masaki Ichijou instead! As the tremors of this announcement ripple through the world, the Shiba siblings will have to navigate more than just their bethrothal!
"All that remains in the Nine Schools Competition are the Monolith Code finals, but with Miyuki's win, the champions have already been decided: First High! Yet, even in victory, not everyone's celebrating: Miyuki can do nothing but worry about Tatsuya. He's left to hunt down the dark organization pulling the strings behind the scenes of the competition, and he won't stop until he's had his revenge. With thoughts of Miyuki filling his head, will he emerge triumphant?"--Back cover.
Two months have passed since the nefarious events surrounding the latest Nine School Competition, and its cerebral counterpart, the Thesis Competition, is fast approaching. Helping out First High with the event, Tatsuya will surely have his work cut out for him even if everything goes according to plan. Of course, nothing ever does, which might explain the letter from Maya Yotsuba containing a curious request: to assist in the capture of Gongjin Zhou, one of the masterminds behind the recent Parasidoll incident. Tatsuya and Miyuki depart for Kyoto, where they'll have to keep their wits about them to safely navigate the hidden schemes and shadowy conflicts that lurk just beneath the surface of the ancient capital!
Though there are only a few scant days left before the National Thesis Competition, instead of preparing for the big day, Tatsuya and Miyuki have traveled to Kyoto in search of the fugitive Zhou Gongjin. They coordinate with Kudou Minoru in what seems like a fruitless search, following leads that lead nowhere-until a Saegusa bodyguard turns up dead by the Katsura River. As they close in on their quarry's hideout, Mayumi joins to seek vengeance and Tatsuya calls upon an old rival for help...
