Despite appearing in previous entries in the series The Valiant Red Peony (1968) as Hanaoka and Red Peony Gambler 3: The Flower Cards Game (1969) as Katagiri, here Ken Takakura plays entirely new but similar wandering character Koji Yashiro, even first arriving on screen in a similar manner carrying a parasol in the rain as in the previous film. Hibotan Oryu meets this third man and appears unfazed as to his unacknowledged resemblance to her other identical friends.
