Spirit Circle Anime Set for December 2026 Premiere

A new supernatural adventure is heading to television this December, as Satoshi Mizukami's acclaimed manga Spirit Circle prepares to make its anime debut. Entertainment company REMOW has confirmed that the adaptation will consist of 18 episodes, with broadcasts scheduled in Japan alongside international streaming availability in December 2026. The announcement was accompanied by a first teaser trailer, promotional artwork, and details about the creative team and voice cast. The preview also introduces the ending theme, "No Matter the World" (Koko ga Donna Sekai Demo), an original song performed by Anna Nagase specifically for the series.

The story centers on Fuuta Okeya, a middle school student with the unusual ability to perceive spirits. His seemingly ordinary existence takes a dramatic turn following the arrival of Kouko Ishigami, a mysterious transfer student who claims that their souls have been connected across multiple lifetimes. Determined to end their cycle of reincarnation, Kouko confronts Fuuta with secrets surrounding his previous incarnations. As he searches for answers, Fuuta is drawn into an extraordinary journey spanning different historical periods and distant futures, gradually uncovering the truth behind their complicated relationship.

The anime features Kazuki Ura as Fuuta Okeya, Anna Nagase as Kouko Ishigami, Eri Yukimura as Rune, and Yūichi Nakamura as East. Production was handled by studios NAGOMI and EOTA, with TWIN ENGINE overseeing the project. The adaptation also carries particular significance as the final directorial work of Tatsuo Satō, known for Martian Successor Nadesico, Stellvia, and Atom The Beginning. Satō was responsible for both directing the series and its scripts before his passing in 2026. Assistant director Kentaro Mizuno subsequently supervised the completion of production, while Satoru Fujimoto handled character designs.

Originally serialized in Young King Ours between May 2012 and 2016, Spirit Circle concluded with six collected volumes. The manga previously reached international readers through Crunchyroll's digital publication service in 2014, while Seven Seas Entertainment later released its English print edition. Its creator, Satoshi Mizukami, is also recognized for The Lucifer and Biscuit Hammer and Sengoku Youko, which received anime adaptations in 2022 and 2024, respectively. The upcoming television series will introduce another of Mizukami's works to anime audiences worldwide.
