Seiji Tamiya

This enigmatic, white-haired woman, composed entirely of artificial parts, wields a glowing, rare jewel pendant and manipulates others with hypnotic power. She harbors a deep-seated desire to control Chiko and inflict despair, ultimately turning allies against her. Revealed as a former lover of Nijū Mensō during wartime scientific research focusing on cybernetics, her pursuit of him led to tragic consequences, culminating in her own demise after finally reuniting with him.
