The official website for the In/Spectre anime has announced that the third season is scheduled to premiere in Japan on January 8, 2023.
The story of the series is described as:
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.
The first season of In/Spectre was a Crunchyroll co-production and part of the Crunchyroll Originals slate. The series premiered in Japan in January 2020, and Crunchyroll simulcast it as it aired in Japan. The service also streamed an English dub for the anime.
