The Irregular at Magic High School

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

A string of bizarre murders occur where most of the blood is drained from the victims' bodies, and they are labelled vampire incidents. Similar murders also occur in America.

The Saegusa and Jumonji families join forces to solve the case; Mikihiko and Erika look for the vampire and confront a mysterious masked magician.

The identity of the mysterious masked magician who engaged in a sword fight with Erika is revealed; the masked magician uses the Parade spell to attack Tatsuya.

A parasite is an information body generated from the spirit dimension; an evil visitor of unknown origin manages to infiltrate First High School.

As Valentine's Day draws near, even those at Magic High School aren't immune to the sometimes tumultuous course of love.
