At the boundary between this realm and another, there live eight million gods, dead spirits who serve the gods, and other assorted spirits who help and meddle in the affairs of humans. A sweet middle school girl named Hiyori Iki has been enduring bullying from her classmates, and she goes to the restroom by herself to cry. Scrawled on the bathroom wall is a phone number and the message, "I solve your troubles."
After Hiyori calls the number, she encounters a homeless boy wearing a jersey who calls himself a god. The boy, named Yato, is rough, moody, lazy, and never listens to anyone's wishes, but he had the power to be a god... that no one knew of.
