University student Hinako Kotori doesn't believe in gods of any kind. If they were real, they would've prevented her parents' murder. So when she meets Aoi, who claims to be the god of unanswered prayers, she laughs him off. Her haughty, blatant disrespect for deities, however, displeases Aoi, who follows Hinako home and whisks her off to his shrine to prove his title of god.
Insistent that she's dreaming or delusional, Hinako attempts to flee, only to end up attacked by demons. Desperate for help, she strikes a deal with Aoi: in exchange for sparing her life, she agrees to assist him in granting the people of Japan their deepest desires -- forever.
Though Hinako's out of danger, she's now bound to Aoi for eternity. Her only hope of returning to the Human Realm is to fully embrace the existence of the gods that failed her. Yet, the deeper she dives into the world of the spirits, the more she learns what really happened to her parents all those years ago. Now Hinako must choose: hang on to the skepticism that's kept her safe, or surrender to the spirits and uncover the truth of her parent's murder.
