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. Tsugumi accompanies Shougo in an undercover mission to learn more information.
I see... But the occasional waltz isn't so bad.

Ya veo, pero un vals
ocasional no está mal.
Je vois.
Però di tanto in tanto

Entendo, mas uma valsa de vez em
quando não faz mal.
Понятно. Но иногда
станцевать вальс можно.
