Hokuto no Ken Episode 38, The Ranzan Kurenai Ken! This Era Has Given Rise to a Truly Tragic Woman! (蘭山紅拳！時代は悲しい女を生んだ！！)

Official synopsis "Your eyes are sad. You are not capable of killing." (Kenshiro). Toki has been taken from the village of miracles and imprisoned in Cassandra, the city where demons weep: a massive prison that the King of Fists, the mysterious man who intends to rule over the end of the century, had built to hunt down martial arts masters. Warned of Kenshiro's approach, the jailer Uighur, who rules over Cassandra, sends Bella, heir to the Ranzan Kurenaiken, against him to exploit his weakness: he cannot kill a woman. Having become heir at the cost of her femininity, by the will of her dying father, Bella reluctantly faces Kenshiro, for the sake of her mother held hostage.
