Having nearly killed himself due to the influence of a cursed tome, Shougo has come to live at Fukurou in order to recover. While Shougo is rude and utterly selfish, Tsugumi finds herself concerned for him. Meanwhile, when a politician jumps to his death due to a cursed tome Fukurou learns that there may be some connection to the dark auctions held behind the scenes of an illustrious dance hall by an organization known as Karasu.
