Five hundred years ago, the Liu clan founded the Spirit-Collecting Pawnshop, trading with the demon race and gathering the spirits of countless monsters. The monsters who traded with them suffered greatly and were left in misery. Five hundred years later, the various realms live in peace. Liu Tianchi, the twentieth-generation descendant of the Liu clan, returns the spirits collected by the pawnshop to their rightful owners, drawing him into one tale after another of old grudges and tangled affections. These stories reveal the suffering of the mortal world and the love and hatred entwining the various realms. Through them, Liu Tianchi also learns the truth about his origins and discovers his own feelings.
