UFS soldier. Driven by her hate for demons and desire for revenge for her family. Yukina is rough around the edges, direct. Simple-minded in her pursuit, and sometimes rude and impatient. Frustrated if she is forced to hold back by her higher ups and that she is looked down upon in these aspects. Otherwise, skillful, loyal and noble as a fighter, which is feared by her enemies. She has long brown hair, purple/blue eyes and mechanical body parts. Curvy body with huge bust.
