A flyer from this year's AnimeJapan 2017 event revealed on Thursday that the television anime adaptation Rin Fujiki's Vatican Miracle Examiner ( Vatican Kiseki Chōsakan ) mystery novel series will have 12 episodes and one OVA. The anime will premiere this summer.

Yoshitomo Yonetani (Food Wars! Shokugeki no Soma, Brave King GaoGaiGar) is directing the anime at J.C. Staff (The Disastrous Life of Saiki K., Little Busters!). Kazunori Iwakura (Aria the Scarlet Ammo, Ai Yori Aoshi) is designing the characters, and Seishi Minakami (A Certain Scientific Railgun, Heaven's Memo Pad) is in charge of series composition.

The novels center on Hiraga Josef Kō, a genius scientist, and Roberto Nicholas, an archives and cryptanalysis expert. The two work as a team as the Vatican's "miracle examiners," traveling the world to investigate the authenticity of claims of miracles.

The flyer describes the story:

To detect lies, refuse fakes, and reach the miracle of God - that is our mission as Vatican Miracle Examiners. Hiraga, a scientific genius and Roberto, an expert on the decryption of cryptography and ancient documents are not only good partners but also "Miracle Examiners" belonging to Vatican branch. They are secret examiners, who are requested to examine and identify the authenticity of miracles from all over the world. They encounter strange events at the places they visit for examination, such as an emerging stigma and an image of the Virgin Mary shedding tears. A bizarre incident suddenly occurs while the authenticity of a miracle is identified. The case file of the genius priest duo has just begun!

Fujiki launched the series under Kadokawa's Horror Bunko label in 2011. Thores Shibamoto (Trinity Blood character design, Attack on Titan: Before the Fall illustrator) designs the covers of the novels. Kadokawa published the 15th volume on February 25. The novels have more than one million copies in print.
