Aoi is a female college student who inherited the ability to see spirits from her late grandfather. She prides herself on her cooking, and one day while feeding some agricultural spirits, a god and the master of the Tenshinya appears and takes Aoi away. He says that due to her grandfather's debts, she must become his bride. Aoi hates this idea and instead declares that she will pay back her grandfather's debt by working at the Tenshinya.
