Princess Cobra
King Cobra awakens the spirit of his daughter in the woman Rankha. Rankha is half-human (human mother) and half-Zensei Majin. This creates terrible conflict within the woman. Rankha has a compassionate heart but Princess Cobra is an unfealing monster. Rankha develops tender feelings for Rai, Kôtaru while Princes Cobra hates him for what he and Diamond Eye did to her father.
Although the Zensei Majin knew early on that there was a link between Rai, Kôtaru and Diamond Eye it was Rankha who figured out that it was Kôtaru's ring which allowed him to summon Diamond Eye.
Rankha usually carries a riding crop which she'll hit both her subordinates and her enemies with.
Rankha was played by Sumida, Kazuyo. She had previously played Rieko in Kikaida 01 (1973) and went on to voice Silencer Despar in "Inazuman Flash" (1974) episode 11.
Princess Cobra is put in charge of a plan to turn humans into Zensei Majin. Of course Rai, Kôtaru and Diamond Eye fight to put an end to this wicked scheme.
