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.

Tatsuya and Miyuki are invited to a party to commemorate the completion of Japan's first hyper-building offshore tower, there Hayama introduces a young girl called Sakurai Minami. The two are shaken upon seeing her face which is that of a woman who died in an incident three years earlier. At such a time, there is intelligence that the party is being targeted by extremist magic advocates — The Advancement of Humanity Front.

But what really bothered her was that he never showed any emotions or thoughts of his own. However, when danger comes calling during a fateful trip to Okinawa, their relationship as brother and sister will change forever…
