Nui Harime is the Grand Couturier of the Revocs Corporation. She is known for her cute appearance, sadistic yet childish nature, and incredible fighting power.
Nui appears to be a young teenage girl of medium height. She has long blonde hair styled in drill-like pigtails, with smaller locks framing her face. Her eyes are sapphire blue, with highlights that resemble a smiling face. She wears a richly adorned pink lolita-styled dress with matching boots and fingerless gloves. She accentuates her ensemble with a parasol, a large pink hair bow, and a purple eyepatch. Her design has a prominent heart motif, such as on her collar, the center of her bow, her earrings, and even the highlights on her pigtails.
Nui has a childlike, jovial, and happy-go-lucky demeanor; always smiling, and acting very friendly and even polite with everyone, demonstrating excessive intimacy towards even
, Nui is free-spirited and will do whatever she wants according to her whims. Her bubbly behavior and nonchalance towards anyone that stands in her way often puts her at odds with the main cast, and can easily become bored while she playfully seeks violence to a sadistic degree.
When she finds herself injured or outmatched, she becomes more frantic, obstreperous, and aggressive, dropping all manner of her cheerful demeanor. She holds heavy grudges against some people.
Nui was born about 17 years before the events of the series prior, following Ragyo's failed attempt to fuse her newborn daughter with Life Fibers. Concluding that a child born by a human cannot merge with Life Fibers, Ragyo created an artificial Life Fiber womb from the mass of the Original Life Fiber, which Nui was grown within. Upon reaching her full development, Nui was raised by Ragyo as a servant of the Life Fibers, becoming the Grand Couturier of the Kiryūin Conglomerate (and of REVOCS as a whole).
Six months before the events of the series, Nui was sent to the Matoi Residence by Ragyo in search of Isshin Matoi's secret creation. After a short battle, Isshin unveiled the Scissor Blades to use against her, but Nui overwhelmed him, stabbing him repeatedly. Before she could deliver the final blow, Nui was distracted by the sound of Ryuuko calling for her father, allowing him to stab her left eye with the purple Scissor Blade. Infuriated by this, she impaled him to the wall with the red Scissor Blade, taking half of the purple blade for herself before planting a bomb in the Matoi Residence and making her escape.
Unbeknownst to Nui, her actions planted the seeds of defeat for Ragyo's ultimate plan. Not only did Isshin trick her into ignoring his real secret project, Kamui Senketsu, but his last act in life would encourage Ryuuko to take up the red Scissor Blade and seek out the one who killed her father.
Following Satsuki's defeat at Honnoji Academy, the Life Fibers began a full-scale takeover of the Earth, seeking to flush out and consume all remaining resistance.
A month later, Ryuuko emerged from hiding, operating independently of Senketsu and Nudist Beach out of confusion and self-loathing over the revelation of her true ancestry. Using her instability, Ragyo and Nui used a pair of COVERS to send a message to Ryuuko, challenging her to face them at Honnoji Academy. Despite the warnings of her allies, Ryuuko obliged, breaking into Honnoji Academy and clashing blades with Nui once again.
During the battle, Nui secretly stitched Life Fiber threads all over Ryuuko's body before taking a seemingly-fatal blow from the red Scissor Blade. After a moment of melodramatic agony, Nui laughed off the injury and pulled out her own heart, revealing that she is also a Life Fiber hybrid. As her injuries healed themselves, Nui explained her origins to her opponent and claimed that she was able to understand Ryuuko's true feelings in a way that no one else could, due to their shared nature.
During the attack on the S.S. Naked Sun, Ryuuko cuts off both of Nui's arms, with the power of the combined weapons preventing them from regenerating. The permanent loss of her arms drove Nui into a demented fury. Before Ryuuko could inflict more damage, Rei Hououmaru took Nui away in a helicopter, leaving an army of COVERS behind to prevent pursuit.
During the final battle, Nui cuts off her own head (as did all of her clones), allowing her to merge with the remains of the Original Life Fiber. Manifesting as an enormous, distorted version of Nui's head, the entity fused with Ragyo, healing her wounds and empowering her even further than before. Nui was last heard expressing her happiness at being worn by her "Mama" before Ragyo blasted off into space to manually initiate the final phase of their plan.
It is unclear what happened to Nui after her fusion with Ragyo, but her consciousness was likely destroyed.
Throughout the series, Nui has displayed several powers, abilities, and skills:
- Regeneration: Nui can regenerate from any wounds and even lost limbs almost instantly, regardless of their severity. The only exception to this healing power is if her entire limb is cut with either the Scissor Blades or two weapons forged from Bazukan.
- Mon-Mignon Prêt-à-Porter: Nui can create replicas of herself that can fight her opponents or act as a distraction. Although identical, the duplicates are far less powerful than the original, relying on their superior numbers.
- Infiltration and Disguise Skills: Nui appears extremely skilled when it comes to mimicry and infiltration. She was able to completely disguise her height, hairstyle, gender, and voice almost perfectly. She was also able to create fake student data, which appeared genuine upon inspection, but disappeared immediately when discarding the disguise. The only clue to her true identity that she could not change was her eyepatch, which she instead covered up. She also appears skilled at puppetry and ventriloquism as she was able to use lifelike puppets to intimidate the One-Star students.
- Piloting Skills: Nui is a skilled pilot, as seen when she hijacked Satsuki's personal helicopter.
- Fingernail Hooks: The bottom edge of Nui's fingernails is lined with small hooks that can catch threads. She can use these hooks to grab and remove Banshis from uniforms.
- Scissor Blade: Nui's signature weapon is one half of a giant pair of scissors. The blade is capable of cutting otherwise indestructible Life Fibers. Her skill with the blade is equal, if not superior to that of Ryuuko's own. Like Ryuuko, Nui can alter the shape of her Scissor Blade. During the S.S. Naked Sun battle, she converted her blade into a large, double-sided scythe.
- Superhuman Physical Prowess: Nui possesses immense physical strength, speed, reflexes, durability, and endurance. She can handle herself exceptionally well in battle, being able to effortlessly fight against the Four Devas, who were all wearing enhanced, Three-Star Goku Uniforms, fight on even grounds against Kamui-wielding fighters such as Satsuki Kiryūin and Ryuuko Matoi, and easily defeat the Nudist Beach forces.
Despite her natural strength, due to the particular nature of the Life Fibers infused to her, she is unable to wear a Kamui as it would not affect her.
- Mental Refitting: Nui can release Life Fibers from her hands that ensnare opponents and turn them into mindless puppets.
- Shapeshifting Arms: For the final battle, Nui's new arms transformed into blades for melee combat and bat-like wings for flight.
- Master Sewing Skills: Being a Life Fibers/human hybrid and the Grand Couturier, Nui has a deep knowledge of how Life Fibers clothing is made, as demonstrated when she effortlessly spotted and removed Sanageyama's uniform's Banshi, dismantling the uniform. Likewise, she altered the Kamui Junketsu to be worn by Ryuuko by sewing the Kamui's Life Fibers to Ryuuko's own for the Kamui to possess her, making it extremely difficult for it to be removed from her body. She can sew high-quality garments, especially Life Fiber-based with ease, even after losing her arms as seen by her completion of the Shinra Koketsu.
- Razor Tape Measure: Nui used a measuring tape with retractable blades during her attack on Isshin Matoi's lab. It was destroyed by the Scissor Blades.
