Baccano! is based on Ryohgo Narita's award-winning light novels of the same title and mainly adapts the first 4 novels. While more faithful to the first 3 novels, the 4th novel (1932) is followed more loosely and is mostly an anime-exclusive story. In addition, content from later novels is briefly included in the anime as well. Unlike the novels however, which follow a mostly linear narrative per book, the anime adopts a non-linear storytelling style; the tale of each novel is told simultaneously with one another, with the focus jumping back and forth in time between and within the different plotlines.
