Yato and Yukine have finally mended their relationship as god and Regalia. As a minor and unknown deity, Yato continues to take odd jobs for five yen apiece in hopes of one day having millions of worshippers and his own grand shrine. He has yet to fix Hiyori Iki's loose soul, but she cheerily prepares for high school nonetheless. While things are seemingly back to normal, the complicated history between Yato and Bishamon—goddess of war and warriors—resurfaces. Bishamon holds a mysterious old grudge against Yato, which results in violent clashes between them. To further complicate matters, Bishamon's most trusted Regalia, Kazuma, is indebted to Yato. When lives are on the line, unraveling these secrets is possibly the only way to correct mistakes of the past.
