Uki doesn't really work under Akumu, being more so an independant worker and the "sister" of Kiki. Just as malicious as her sister, Uki is a sadistic woman who follows more along the sensual way of doing things unlike her brutish sibling. Sex is a weapon- though not as much as her ACTUAL weapons- taking advantage of her curvy form. Her voice ranges from loving and sensual to nearly insane and malevolent, finding great pleasure in making her victim suffer.
