Spirit Circle Anime Arrives December 2026 as Director's Final Work

Spirit Circle is getting an 18-episode anime adaptation, and this one lands differently. Director Tatsuo Sato's final project, the series premieres in December 2026—months after Sato passed away in April 2026.

The story follows Fuuta Okeya, a high school student who can see spirits. His world shifts when Kouko Ishigami shows up determined to kill him, the two bound by a curse that stretches across multiple lifetimes. Fuuta has to dig into his past lives to understand what ties him to Kouko and whether the cycle can break.

NAGOMI and EOTA are handling production, with TWIN ENGINE overseeing the full project. The voice cast has Kazuki Ura as Fuuta, Anna Nagase as Kouko, Eri Yukimura, and Yuichi Nakamura in supporting roles. Nagase also performs the ending theme, "Koko ga Donna Sekai Demo."

Satoshi Mizukami's Spirit Circle already has a following for how it handles reincarnation and interconnected destinies. Eighteen episodes means the production is giving the source material real room to breathe—enough space to work through the manga's layered narrative and the reveals about how these characters' fates connect, without cutting corners.
