Moyu Miyama, a wealthy student at Golden Star Academy, is recruited by Aphrodite to join the Venus Warriors. Transforming into Venus Red, her designated color reflecting her role, she bears a red Venus mark on her buttocks signifying her selection.

Initially displaying a snobbish demeanor consistent with her background, Moyu enters the academy with an aloof attitude. Through continued association and shared experiences with her Venus teammates, she gradually sheds this isolation, lightening her manner and growing into her role within the Venus 5.

As Venus Red, she gains unspecified supernatural abilities. She fights alongside her team against the Inma Empire, led by Necros, which seeks to resurrect Apollo, the god of lust, and impose a global regime centered on perversion. Moyu's journey centers on evolving from a status-conscious individual into a cooperative warrior through her deepening team connections.
