Following the events of "Scorched Halloween," the UNSA dispatches the most powerful asset in its arsenal to Japan to uncover the identity of this person—the elite magician unit "Stars".

Meanewhile, Tatsuya and his friends are having a farewell party for Shizuku, who is leaving to study abroad. Around the same time, Tatsuya is informed about the USNA's plan to uncover his true identity.

Elsewhere in Tokyo, numerous reports arise of seemingly random bodies found drained of blood. It does not take long for Tatsuya to realize that it is not a mere coincidence.
