In a northern city after the Silver-Wing War, Osvaldo, a butcher at the members-only restaurant Ombrello, encounters a man claiming to be a vampire. Joined by the beautiful boy Luca and Everis, a former princess turned assassin, he is drawn into a dark world through the mystery of a man who had been frozen as food.

A mystery born from an encounter with a vampire leads a group of butchers racing through a postwar city toward a dangerous truth.
