The Irregular at Magic High School (Simuldub)

Two months after the Scorched Halloween incident, Tatsuya and his friends hold a going-away party for Shizuku who will be studying abroad in America. With the start of the new semester, an exchange student from America arrives at First High School.

A string of bizarre murders occurred where the victims were found to have most of the blood drawn from their bodies. Due to the methods used by the killer, they were called "vampire incidents," and similar incidents were also occurring in America.

The vampire that attacked Leo was a demon called a "parasite." The Saegusa and Jumonji families decide to join forces to solve this case. Mikihiko and Erika search for the parasite to get revenge for Leo, and they confront a mysterious masked magician.

It turns out that the masked magician that engaged in a sword fight with Erika was Lina. With her identity blown, Lina uses the Parade spell to attack Tatsuya. Tatsuya attempts to disable the Parade spell by dismantling it but fails.

A parasite is an information body that was generated from the spirit dimension. How could an entity from another dimension appear in the physical world? An evil visitor of unknown origin infiltrates its way into First High School.

Valentine's Day is a day to gift chocolate to the one you love and confess your feelings. This tradition is a source of joy and grief for many even at a distinguished institution like Magic High School. What will happen this year on Valentine's Day?

Colonel Balance orders Lina to capture the caster who was behind Scorched Halloween. Balance gives Lina a custom-made device called "the Brionac" which converts Strategic-Class magic into a beam of high-energy plasma.

The Yotsuba Family intervenes to eliminate all threats to Tatsuya from the USNA military forces. After questioning Pixie about the remaining parasites, Tatsuya heads to Aoyama Cemetery with Miyuki and Honoka to lure them out.

Thanks to Pixie's psychic powers, Tatsuya and his friends are finally able to capture the parasites. They leave the scene after Erika and her team arrive, but a third faction disguised as the police appear before them and get in their way.

As instructed by Raymond, Tatsuya and his friends head to the outdoor training area behind First High School and detect the presence of parasites gathering at the scene. A clash with Lina, who is hell-bent on completing her mission, is inevitable.

About a month after the parasite incident, Tatsuya and his friends reluctantly bid farewell to Mayumi, Mari, Katsuto and the other seniors at the 29th graduation ceremony at First High School.

Tatsuya and Miyuki are invited to a party celebrating the completion of Japan's first hyperbuilding, Tokyo Offshore Tower. At the party, they are astonished when Hayama introduces them to a young girl named Minami Sakurai.

The New Breed Front announces that they are going to blow up the Offshore Tower in one hour. In order to foil the New Breed Front's plans, Tatsuya and Miyuki take Minami and head for the control center on the first underground floor.
