Spirit Circle

Fuuta Okeya lives a quiet life in modern Tokyo until Kouko Ishigami transfers into his class and immediately claims he is her enemy. The conflict stems from a birthmark on Fuuta's neck, which triggers memories of their past lives as enemies during the Boshin War of 1868. As Kouko forces him to confront these fragmented recollections, Fuuta discovers that both of them are part of a larger circle of souls reincarnated from victims of that historical conflict.

The narrative shifts between contemporary Japan and the Bakumatsu era, revealing how specific betrayals and murders from the late Tokugawa period echo through centuries. Each character carries the trauma of their previous death, creating a cycle of vengeance that only ends when they understand the full scope of their shared history. Mizukami uses this structure to examine how unresolved guilt can haunt individuals long after the original events have concluded.

Published by Kodansha in Weekly Young Magazine, the series ran from 2008 to 2014 before concluding its run. Yen Press later handled the English translation, releasing the volumes over several years to reach Western audiences. The story stands out for its ambitious blending of real historical figures with fictional supernatural elements, offering a unique perspective on Japan's transition from feudalism to modernity. [edit]
