Aoi Tsubaki inherited her grandfather's ability to see spirits--and his massive debt to them! Now she's been kidnapped and taken to Kakuriyo, the spirit world, to make good on his bill. Her options: marry the head of the inn her grandfather trashed, or get eaten by demons. But Aoi isn't the type to let spirits push her around, and she's determined to redeem her grandfather's IOU on her own terms!

Aoi is finally ready to open her restaurant on the grounds of the Tenjin-ya inn, but not everyone is as excited about it as she is. Some of the chefs of the main restaurant are doing everything they can to destroy her business before it even has a chance to start! Aoi is determined to keep going, but her detractors are deadly serious about stopping her.
