Sayaka Yumi

Sayaka Yumi is the daughter of Dr. Gennosuke Yumi, head of the Photon Power Laboratory. She became the test pilot for Aphrodite A, a robot originally designed for geological research that was later adapted for combat.
When Dr. Hell and his army of Mechanical Beasts threaten Japan, Sayaka joins Koji Kabuto and Boss in defending the country. While Boss harbors an unrequited crush on her, Sayaka’s relationship with Koji is marked by friction due to his brash attitude and tendency to undervalue her contributions. Despite their frequent disagreements, Sayaka, Koji, and Boss form a formidable team, learning to respect and rely on each other as they face the ongoing threat.
