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!

Two of Aoi's new friends have been acting strangely ever since the guests from their rival inn Orio-ya arrived at Tenjin-ya. With the Ōdanna's support, Aoi decides some gentle meddling is in order. But while her good intentions seem helpful at first, she ends up biting off way more trouble than she can chew!
