The Irregular School explores the foundations of the current controversies and argues that continuing to think in terms of the regular school or the special school obstructs progress towards inclusive education.
April, 2096. Despite all the commotion they were involved in, Tatsuya and Miyuki have safely advanced to become second years. In light of all of Tatsuya's accomplishments, a new curriculum known as the Magical Engineering Course has been established, granting him a new place in school. With his new classes and 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 new students from elite Numbered families raise hell as first years!!
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!
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...
In 2092, Okinawa was suddenly invaded without warning by an unknown enemy force. Miyuki and her mother were caught up in the battle that ensued, leaving them in dire straits where they were all but helpless, relying on the help of a lone young man...named Tatsuya. This is the story of how the Shiba siblings got where they are now!
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!
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. Meanwhile, the ace of Third High, Masaki, entertains Kichijouji at home, unaware of his partner's struggle...or jealousy. Shun finds himself playing bodyguard to a beautiful foreigner, and Emi 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!
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!
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!
