The official website for the television anime of Kyo Shirodaira and Chasiba Katase's In/Spectre (Kyokō Suiri or Invented Interface) manga announced on Tuesday that Akari Kitō and Mamoru Miyano will star in the anime as Kotoko Iwanaga and Kuro Sakuragawa, respectively.
A commercial promotes the April 17 release of the 10th manga volume, and it previews the characters' voices:
When she was still just a girl, Kotoko was kidnapped by yokai. These spirits made her into a powerful intermediary between the spirit and human worlds, but this power came at a price: an eye and a leg. Now, years later, she watches out for dangerous yokai while developing feelings for a young man named Kuro, who is also special: an incident with a yokai has given him healing powers. He's surprised when Kotoko asks him to team up to handle renegade yokai, preserving the thin line between reality and the supernatural.
Keiji Gotoh (Kiddy Grade, Endride, Sengoku Collection) is directing the anime at Brains Base, and Noboru Takagi (Durarara!!, Golden Kamuy, Kuroko's Basketball) is in charge of the series scripts. Takatoshi Honda (RIN-NE conceptual design) is designing the characters and serving as chief animation director. NAS is presenting the project. The staff has not yet announced the broadcast schedule and cast.
Katase launched the manga based on a 2011 novel by Shirodaira (Spiral, The Record of a Fallen Vampire, Blast of Tempest) in Kodansha's Shōnen Magazine R in April 2015. The manga is Katase's first serialized work. It was nominated for Best Shōnen Manga in the 42nd Annual Kodansha Manga Awards in 2018.
Kodansha published the ninth compiled book volume of the manga in Japan last October and is publishing the manga's 10th volume in April. The first nine volumes have 2 million copies in print. Kodansha Comics published the ninth volume in North America in February.
