Among other returning cast members here playing new and different but similar characters, Kyôsuke Machida appears as a different yakuza underling than in previous entries in the series, and Kôji Tsuruta again plays a soft-spoken single father, different than the one he previously portrayed. Kanjûrô Arashi here plays a new oyabun than the ones he portrayed in Red Peony Gambler 3: The Flower Cards Game (1969), Hibotan bakuto: Nidaime shûmei (1969), and Hibotan bakuto: Oryû sanjô (1970), dying in each instance. Oryu is apparently oblivious to their resemblance to her previously encountered friends.
