Kyala, an immortal warrior born in 16th-century Japan, perished in combat only to be resurrected by Marcus Octavius, who molded her into his protégé, lover, and merciless enforcer. Embracing his corrupt philosophy, she honed lethal skills marked by agility, speed, and surgical precision, favoring concealed needles embedded in her signature green heels. Though she abandoned her katana, she retained mastery of bladed weapons and piloted advanced aircraft like helicopters with cold expertise.

In 2187, Kyala clashed with Colin MacLeod during his feud with Marcus. Dahlia, Colin’s lover, delivered a mortal blow, but Kyala revived and retaliated by stabbing her rival. Unaware of Dahlia’s lingering resolve, Kyala fell victim to a grenade concealed in her mouth during the struggle—the detonation obliterating her body and scattering her Quickening, ending her immortality.

Her striking appearance featured a lithe, muscular frame adorned in a green dress with intricate string detailing that accentuated her cleavage, paired with tall green heels. Short black hair, loop earrings, and a demeanor blending cruelty with unwavering loyalty to Marcus defined her. Once, after resurrection, she challenged Marcus about his divinity, met only by an enigmatic reply—a fleeting glimpse into the twisted bond anchoring her to his ambitions.
