*Nui Harime is the secondary antagonist of the 2013 anime Kill la Kill. She is the Grand Couturier in service to Ragyo Kiryuin as one of her top two subordinates, alongside Rei Hōōmaru. She is also the one who killed Ryūko's and Satsuki's father, Sōichirō Kiryūin disguised as Isshin Matoi.

Nui is a human-Life Fiber hybrid that Ragyo created 17 years prior to the series by artificially incubating her within a Life Fiber womb created from the mass of the Original Life Fiber, raised to serve as the Life Fibers as the Grand Couturier of the Kiryūin Conglomerate and REVOCS.

Six months prior to the story, Nui was sent to the Matoi Residence on Ragyo's order to kill Isshin Matoi and take what he was developing, managing to fatally wound Isshin and took the half of the Rending Scissors that the scientist used to destroy her left eye.

But she later learned that she failed in her mission as Isshin's actual secret weapon, Senketsu, ended up with his daughter Ryuko Matoi who resolved to track down her father's killer. This motivates Nui to target Ryuko out of frustration over Isshin making a fool out of her.*
