Nui Harime is the Grand Couturier of the Revocs Corporation, whose strength is even feared by Satsuki. She wields a purple scissor blade, the other half of Ryuuko's red blade. Nui also declares herself to be the one who murdered Ryuuko's father, Isshin. Nui revealed that she was born from an artificial womb made of life fibers, thus making her the same as Ragyo and Ryuuko. She goes on to say that Ryuuko and herself are sisters.
