After Rin's father died, One day, a group of men having white hair showed up at her house and demanded the money her father owed them. She failed to fulfil the demand and was forcibly taken to their Tairi Realm. There she came to know they are "Tairin", spirits who feed on people's greed.   She is introduced to a spirit named "Haiji", the leader of the "Ika Tairi" family. He explained that her father owed them 50kg gold, but now that he is dead, it should be paid by her daughter.   Haiji states that the only way to settle the debt is by marrying him or paying with her blood. She refuses and decides to pay the debt on her own terms - by getting a job in Tairi Realm.   This marks the start of a thrilling yet hilarious journey of solving mysteries, fighting Tairins and deception. Along the way, she proceeds to change and touch the lives of the Tairins, bringing chaos and unexpected trouble; she slowly realizes that Haiji holds more feelings for her than he is revealing.
