Formerly Clone No. 8 of the Silver Squad. Like Anby and Soldier 11, she has silver hair and orange eyes. She is 158cm tall. While she possessed the lowest combat power among the clones, she was highly intelligent and displayed exceptional talent in strategy. During the final, effectively suicidal mission intended to purge the Silver Squad—which Soldier 11 did not attend—her limbs were corrupted. Her left arm and both legs were replaced with prosthetics, and she lost her left eye, which she now covers with an eyepatch. Afterward, she passed through the hands of various people who found her, eventually being sold into human trafficking. She finally met a former military surgeon and was provided with the cloning technology used to create the Silver Squad. She is now planning to use this technology to rebuild the Silver Squad. Having endured horrific treatment—being sold like an object due to her corrupted limbs and having her internal organs rummaged through as an experimental subject without anesthesia—she has become incredibly bitter and spiteful. Twiggy once believed Anby had abandoned her, but she now knows that wasn't the case. She longs for a peaceful daily life with her sisters again, but believes her broken self is no longer worthy of it. She loves her sisters dearly. Twiggy has a foul mouth. Twiggy has a strong sense of family love. Twiggy is deeply distrustful of humans.
