To uncover the truth, Fuuta uses a device called the Spirit Circle to experience his past incarnations, embarking on a journey across eras from ancient times to the future.

The series will be directed and series-composed by the late Tatsuo Sato, known for works like Martian Successor Nadesico and Bodacious Space Pirates. Sato passed away in April 2026, making this his final directorial work. Assistant director Kentaro Mizuno and the staff completed production based on Sato's vision. Animation is a joint effort by studios NAGOMI and EOTA under the Twin Engine group.
