Teman sekelas Shiba Miyuki, Kitayama Shizuku, mendapatkan kesempatan untuk belajar di luar negeri. Bagi ahli sihir, hal ini bukanlah sesuatu yang biasa karena ahli sihir yang memiliki kemampuan besar itu sudah dianggap seperti aset negara. Tapi, mereka membuat sebuah pengecualian khusus untuk satu program pertukaran siswa. Dan itulah yang menyebabkan Angelina Kudou Shields datang ke Jepang untuk belajar di SMA Satu.Saat Lina sampai di Jepang, muncul beberapa insiden misterius di mana korban insiden tersebut kehabisan darah seperti diserang oleh vampir. Bisakah Tatsuya mengungkap keberadaan vampir tersebut?

=====
Shiba Miyuki's classmate Kitayama Shizuku is on her way to study abroad. For magicians, this is normally impossible, since allowing the genes of someone who can use magic outside their home country's borders is tantamount to giving up national secrets. But it's allowed to happen in one case-exchange programs. And that's how Angelina Kudou Shields has arrived in Japan from the USNA to study at First High.

Around the time Lina arrived in Japan magicians began getting attacked by a mysterious being who leaves his victims drained of blood. Will Tatsuya be able to discover the identity of the "Vampire"?
