The manga inspired the Ga-Rei: Zero prequel television anime in 2008 and Funimation released the series on home video in North America.
The novel is a prequel to both the main manga and Ga-Rei: Zero, and is labeled as the story “where it all begins.”
Segawa is credited for the original work and the novel’s illustrations, while Katsuhiko Takayama, the writer for the Ga-Rei: Zero prequel anime, wrote the novel.
Segawa published the supernatural action manga Ga-Rei from 2006 to 2010 and Kadokawa published the series in 12 compiled volumes.
