Vatican Miracle Examiner

The flyer from this year's AnimeJapan 2017 event revealed that Vatican Kiseki Chousakan will receive an OVA episode.

The year is 1928 A.D. The place is New York, U.S.A. The economic prosperity brought forth after the Great War also heightened the presence of something far darker and much more sinister: the demonic Sinners. The Magdalene Order is an organization that tries to counter this force. Two of its exorcists are Rosette Christopher and her assistant, Chrono. Both appear out of place in an organization like this, and they are in a quest to find Rosette's missing brother, Joshua. Their relationships, secrets and fates can only be revealed in time...

Takeru Aoyama, a young man, continues his journey in search of the Three Sacred Treasures in order to save humanity, bravely contending against the Chimimouryou (evil spirits of the mountains and rivers in the mythical Japanese bestiary).

The Miracle of Excalibur is the twelfth OVA of the anime and manga franchise Detective Conan. The plot is based on Gosho Aoyama's short story "Excalibur".
