- In the afterword, Narita explains that the 1933 arc was inspired by the issue of Jing Shinonome's joke-based comic Four-Panel Jack that appeared in Volume 29 of the magazine Dengeki hp. Shinonome often parodied light novels in Four-Panel Jack, and happened to be parodying Baccano! in that volume; one strip featured Firo, the other featured Tick and Maria. Narita had asked Chief Editor Suzuki if he could treat the 4-koma jokes from Four-Panel Jack as fact, and, upon receiving approval, plotted out 1933 accordingly.
- The title of the volume is a reference to the band The Clash.
