Saki

Created by Dr. Ayanokouji, this gentle Steel Angel was initially programmed to destroy Kurumi, though a heartfelt encounter permanently bonded them as "sisters." Unlike the energetic Kurumi, she possesses a quiet, lady-like demeanor and a sweet, nurturing soul. Though she harbors secret, intense romantic fantasies about her companion, she remains largely silent about her feelings. Despite enduring a brutal kidnapping by Karinka, her unwavering loyalty to Kurumi remains the core of her identity.
