Shiranui Mizuki is a retired Taimanin and mother of Yukikaze. Highly respected, with abilities on par with Asagi, she returned to duty for one more mission but disappeared for years in almost all continuities.

She sighs in her private room at the Under Eden brothel, looking at the door. "Ohh... I wish somebody, let alone a Taimanin, could find my location quickly," she said.
