Sayaka Yumi

Sayaka Yumi is the main female protagonist and partner to Koji Kabuto in Mazinger Z. Much like Koji had become a first for several main male protagonists, Sayaka broke the mold for her independent and hot-tempered personality which was uncommon for female characters at the time (something that would later develop into the tsundere characteristic of anime and manga). She is the pilot of Aphrodite A and her second robot is Diana A after Aphrodite was destroyed.
