BACCANO! (2015 Manga)

From October 16, 2015 to January 6, 2017, a manga simply titled BACCANO! (バッカーノ! Bakkāno!) as drawn by Shinta Fujimoto was serialized in the Young Gangan magazine. The manga ran for twenty-two chapters altogether, which Square Enix compiled into three volumes.

Two months after Japanese serialization began, Yen Press announced on Twitter that it would start digitally releasing its English translations of the manga's early chapters leading up to simultaneous publication in January. Yen Press has since published all three volumes in digital and paperback formats. The translator, Taylor Engel, would later become the official translator of the Baccano! light novel series the manga is based on.

In early October 2019, Young Gangan announced on Twitter that BACCANO! would be made available to read on 'MangaUP!', Square Enix's official manga-reader app. In association with the announcement, Fujimoto drew and shared a small comic depicting how the manga was decided upon and greenlit.

BACCANO!'s first volume features a brand new mini-arc detailing the events of the Feast of San Gennaro in 1927 alongside a brand new character, both of which would consequently be referenced in the main text of 1935-D Luckstreet Boys. The rest of the manga adapts The Rolling Bootlegs, and is the most faithful visual adaptation of the novel to date.

In 1935-D Luckstreet Boys ' afterword, Ryohgo Narita enthusiastically praises the quality of Fujimoto's adaptation and credits it with further fueling his motivation to finish writing the novel.
