Cyan Bluestar

Cyan is a mysterious artificial human girl who claims to be the younger sister of the protagonist Rouge, possessing the ability to transform into a blue gladiator. Initially under the control of the 'Puppeteer,' she repeatedly attacked Rouge, but after being defeated and reclaiming her own consciousness, she switched sides to fight alongside her. Even in the later stages of the story, when the Father of Artificial Humans, Roy, attempted to seize her mind, her formidable inner will allowed her to resist his manipulation, making her a pivotal figure in shaping the course of the narrative.
