The Mystic Archives of Dantalian

About the story

Huey (voiced by Daisuke Ono) comes from an aristocratic family. His grandfather, an obsessive collector of rare books, dies in an accident, leaving behind an old estate and a house full of books. His will states that anyone wishing to inherit the mansion must also inherit the Bibliotheca Mystica de Dantalian. After receiving the letter, Huey visits the mansion and encounters a mysterious girl named Dalian (voiced by Miyuki Sawashiro) among the piles of books in the basement. While investigating his grandfather's death, Huey goes to Conrad's mansion and witnesses terrifying scenes caused by a Phantom Book. "Phantom Books" are fantastical volumes that should not exist. They contain powerful forbidden forces that can grant their readers boundless blessings, but can also overturn the world and cause its collapse. The Bibliotheca Mystica de Dantalian seals these books away. Dalian orders Huey to produce the key and recite an incantation. The enormous lock on her chest gleams with a metallic sheen: Dalian herself is the entrance to the Bibliotheca Mystica de Dantalian… This anime is adapted from Gakuto Mikumo's light novel of the same name.
