Roze

Roze is the deuteragonist of the "Sky Striker" story. She is based on the card "Sky Striker Ace - Roze" from the Yu-Gi-Oh! Official Card Game and Trading Card game.

In the manga, as Raye's Sky Striker equipment vastly outclasses AI in combat but can only be used by a human operator, Roze was genetically engineered by the robotic "Pillars of Spectra" sorely to go toe-to-toe with her by using the same technology. However, as she starts developing a personality of her own, the Pillars plot to replace her with her clones Azalea and Camellia; Roze initially reacts by competing with them and redoubling her efforts to kill Raye, but eventually ends up siding with her.

In the anime, she is a normal girl raised like a weapon and used as one of the few human soldiers in the conflict itself, which is fought almost entirely with drones. However, one day she comes face to face with another human who is fighting for the other side: Raye.
