The manga is set in a world where the gods have passed down their power to hold back calamity to family lines of shrine caretakers, who are only able to bear female heirs. The story centers on Souta, an unprecedented male heir to one such family, who has an encounter with a girl and the supernatural on his 18th birthday. Souta becomes involved in a conflict that stretches back to the mythological age of Japanese gods. (Source: ANN)
