Kaiji and Akagi, both adapted by Madhouse from Nobuyuki Fukumoto manga, share many surface similarities — the art style is the most obvious, but they’re both also filled to the brim with scumbags who derive great pleasure from inflicting physical and psychological torture on any human who stumbles onto their path; shady mob underworld settings; and a focus on gambling through heavily psychological games. However, these elements lead both series down wildly different paths — this is most apparent with the protagonists.
