In one of the final scenes, several yakuza members approach a theatre playing Onna Toseinin, aka Okoma: The Orphan Gambler (1971) and ogle the poster featuring Sumiko Fuji as the latter movie's theme music plays. Onna Toseinin is a "ninkyo eiga" or "chivalry film" in which yakuza are portrayed in a romanticized way as honorable, upstanding citizens, or cool, wandering gamblers. This is certainly meant as a strong contrast to the "jitsuroku eiga" / "actual record film", or true crime style of this Battles Without Honour and Humanity series, in which modern yakuza are more accurately portrayed as brutally destructive, craven goons engaging in chaotic violence and murder. Ironically, Yumiko Nogawa who appears in this film as a yakuza wife, 12 years earlier appeared in an early ninkyo eiga series of her own as a similar wandering woman gambler character, Toba no mesu neko (1965).
