Miyuki Shiba’s classmate, Shizuku Kitayama, goes to study in America. Usually that isn’t allowed: anyone with the ability to use magic can’t be outside their country’s territory—it's like exposing all its national secrets. However, there is one type of trip that doesn’t fit that rule: an exchange of programs. Thus, becoming an exchange student, Angelina Kudo Shields arrives in Japan from USNA to study alongside the main characters.

Will Tatsuya be able to uncover the identity behind the “vampire”? (с)
