Satoshi Mizukami's Spirit Circle is becoming a TV anime. Per Anime News Network, the 18-episode series premieres in December 2026 in Japan and streams globally at the same time. The first teaser, visual, cast and staff list went live on Thursday.
Quick answer
Spirit Circle is an 18-episode TV anime from Twin Engine, based on Satoshi Mizukami's manga (2012-2016, six volumes). It premieres in December 2026 with a global simulcast; the streaming service has not been named in the sources. Kazuki Ura voices Fuuta Okeya, Anna Nagase voices Kouko Ishigami, and the ending theme "No Matter the World" is performed by Nagase. Director Tatsuo Satō, who died before release, finished it as his final work.
The pitch
Fuuta Okeya is a middle schooler who can see spirits. A mysterious transfer student, Kouko Ishigami, tells him she will destroy his soul and break the cycle of reincarnation, because the two are bound by past lives. Fuuta then travels through his own previous lives, from the ancient past to the far future. It is a reincarnation tale built as a time-hopping mystery, and Mizukami has a reputation for that kind of structure.
The cast and the staff
Eri Yukimura plays Rune and Yūichi Nakamura plays East. Satō directed Martian Successor Nadesico, Stellvia and Atom The Beginning, and also handled the series scripts. Assistant director Kentaro Mizuno led the production to completion, Satoru Fujimoto designs the characters, and the work is credited to NAGOMI and EOTA with Twin Engine producing. Knowing it is Satō's last project gives the premiere extra weight for longtime fans.
Where it fits
If you liked reincarnation dramas that play with time, this lands in a crowded December slot. See what to watch in winter 2027 for the rest of the season's pipeline.
