Yuko Sagiri

Yuko Sagiri is one of the head doctors at Mochizuki Hospital and a member of Black Label. She is also Yoko Sagiri's younger twin sister and one of the main female protagonists of the series. Yuko is a beautiful, tall, and voluptuous young woman with big amber eyes, a large bust, and long brown hair that trails all the way down to her thighs. She is well-known for her good looks and her shapely figure, both of which had garnered her a great deal of attention from both genders. She also has an Ampoule tattoo on her left breast and her hair changes color to white whenever she's in combat. Her vigilante outfit consists of transparent combat glasses, white gloves, tight white pants, white high-heeled boots, and a low-cut white jacket that exposes both her stomach and her hips. When she was a teenager, Yuko's curves were not as prominent and her bust was noticeably smaller. Her hair was also much shorter and was barely long enough to reach her shoulders. Yuko is a gentle and warm individual who often behaves in a casual and carefree manner. She is also quite levelheaded and rarely ever shows signs of panic or distress. At the same time, however, she takes both her job as a surgeon and her role in Black Label very seriously. She also prides herself on being able to kill so efficiently that her victims die painless deaths and is absolutely merciless in battle, as shown by how she has no problem hacking her enemies into pieces in order to accomplish her missions.
