Ikumi Mihara is a newly enrolled student at Golden Star Academy. She exhibits a soft-spoken and kind-hearted demeanor, belying a tougher aspect forged by her prior involvement with a gang at her previous school, a past that fuels a core resilience.

Chosen by the Greek goddess Aphrodite as one of five warriors defending Earth from the Inma Empire, she becomes Venus Green. Her transformation bears a distinctive green Venus symbol on her left thigh, signifying her connection to the Venus powers.

As Venus Green, she joins forces with the other Venus warriors to combat Necros and the Inma Empire's campaign to resurrect Apollo and impose global domination through lust. Buccha, the talking cat servant of Aphrodite tasked with assembling and guiding the warriors, finds Ikumi and informs her of her destiny.
