Hiyori Iki survives being hit by a car while apparently saving a young man named Yato, but afterward her soul can leave her body. She demands that he restore her to normal. Yato is a minor deity, however, and helping her requires a new weapon partner—a search Hiyori reluctantly agrees to join.
Calling himself the "Delivery God," Yato takes odd jobs for five yen each and hopes to one day have millions of worshippers. For now, he has no shrine to his name, and his previous weapon partner has abandoned him after growing tired of her master. Hiyori needs his help, while Yato needs a partner to provide it, drawing the middle school girl into the struggling god's search.
