Shinta Fujimoto is the illustrator of the 2015 BACCANO! manga adaptation. He is also the creator of the now complete manga series Red Raven. Having long been a fan of the Baccano! light novel series, he expressed eagerness and enthusiasm in the BACCANO! project on his twitter account, where he still occasionally continues uploading drawings of Baccano! characters.
Ryohgo Narita credits Fujimoto's BACCANO! manga in the afterword for 1935-D: Luckstreet Boys as what gave him the motivation and inspiration to write for Baccano! after two years minimum of not writing the series.
In September 2017, Square Enix announced that Narita and Fujimoto have been collaborating on a new original manga called Death Mount Death Play, which would go on to debut on October 20, 2017. Despite Narita's joint problems as confirmed on October 2017, he wrote the manga's manuscript months in advance and its debut proceeded as scheduled.
