Kakuriyo no Yadomeshi

かくりよの宿飯

After losing her grandfather, Aoi inherits his ability to see spirits known as ayakashi. Taking it all in stride, she takes to feeding the ayakashi until one day, an ogre appears demanding she pay her grandfather’s debt. His price? Her hand in marriage! Refusing this absurd offer, Aoi decides to work at the Tenjin-ya—a bed and breakfast for the ayakashi—to pay back what her family owes.
