Ragyō Kiryūin

Ragyō Kiryūin (鬼龍院 羅暁 / きりゅういん らぎょう) is the mother of Satsuki Kiryūin and Ryūko Matoi. She is the CEO of the Revocs Corporation, as well as the chair of Honnōji Academy's board of directors. In Episode 17, she becomes the primary antagonist of Kill la Kill, and replaces Satsuki.

Appearance
Ragyō's most prominent feature is her resplendent multi-colored hair, with a silver color on top. She has a very attractive and authoritarian appearance, and is at all times flaunting glamorous dresses. She seems to be quite tall as well.

She has seven star-shaped scars on her back that greatly resemble the ones emblazoned in Goku Uniforms possibly because of her being fused with Life Fibers leaving those seven scars.

Personality
Ragyō is a character bathed in luxury, and it shows in her overall presentation and attitude. She is vain and proud, and boasts her power and status abundantly. According to Rei Hōōmaru, her character and morals are at the very least questionable.

She is impeccably devoted and loyal to the Life Fibers, and has little regard for human life-seeing herself above human-using her infant daughters as experiments. Ragyō, like Satsuki, is willing to indulge her inferiors whims, and is quite personable with those loyal to her. She even, in some way, takes some pride in her daughter's success, and is surprised that Satsuki would betray her. However, she is is also shown to be quite sadistic and ruthless, brutalizing Satsuki while maniacally taunting and laughing at her. She even went as far as to ambush and tear out Ryūko's heart and show it to her, simply to make a point. She enjoys domination and control, lusting for power over everyone and everything in the world.

Her cruelty is shown to be even more sinister, as she has on many occasions been disturbingly inappropriate with her daughter, fondling and even sexually assaulting Satsuki. It is implied that this abuse has gone on for years. This is later seen again with her younger daughter Ryūko. She also does this to herself in episode 23. All of this may be done because she just enjoys the mere fact of dominating someone or something.

Satsuki Kiryūin
She is Ragyō Kiryūin's eldest daughter, and they share a complicated relationship. Ragyō exposed Satsuki to Life Fibers in an experiment to attempt to lower the infant's resistance to them. When the experiment showed that Satsuki could not overcome her body's natural resistance to fibers, Ragyō decided instead to use Satsuki as a tool for COVERS. Upon Satsuki's betrayal, although surprised, Ragyō had no qualms with brutalizing her daughter and taking her captive. Ragyō also sexually abuses her, and it is implied that Satsuki has been enduring this abuse for years.

Ryūko Matoi
She is Ragyō's younger daughter who was presumed dead after a supposedly failed experiment that involved fusing Ryūko's body with Life Fibers. It was found out that the experiment did not quite fail, and as a result Ryūko's body is completely merged with Life Fibers. Later, Ragyō would try to lure Ryūko to Honnōji Academy in order to trap her with help of Nui Harime. The plan succeeded; Nui and Ragyō managed to forcibly have Ryūko wear Junketsu, brainwashing her in the process and making her attack Nudist Beach and the Student Council.

Nui Harime
Nui assists Ragyō with her plan, although she says that she does what she wants on her own whim. She seems to be on friendly terms with Ragyō. Nui, however, was created by Ragyō in an artificial Life Fiber womb, presumably after having believed that she failed at fusing her newborn daughter with Life Fibers.

Rei Hōōmaru
As a Revocs Corporation officer and Ragyō Kiryuin's personal secretary, Rei has shown to be fiercely dedicated to Ragyō and her insane ambitions. Rei has even gone so far as to risk her own life to defend Ragyō from physical harm.

Powers & Abilities

 * Life Fibers Manipulation
 * Superhuman Physical Prowess - Ragyō's physiology has been enhanced with Life Fibers. Because of this, she has superhuman strength, speed, reflexes and durability, enough to physically overpower two Kamui-wearing opponents, Ryūko and Satsuki with relative ease, even though both had substantially developed their Kamui and Life Fiber-based powers. She was also able to break Satsuki's blade, Bakuzan, a blade develop to sever Life Fibers with her bare fist.
 * Enhanced Healing - Due to the power of Life Fibers dwelling inside of her body, Ragyō can regenerate any wound inflicted on her almost instantly, even being decapitated at the hands of her daughter Satsuki. The exception to this is if she is cut by either the Bakuzan or the Scissor Blades from two different directions.
 * Mental Refitting (精神仮縫い) - By sewing Life Fibers known as Marionette Threads into the brains of her victims, Ragyō can bend anyone to do her bidding. An exception to this power is Ryūko Matoi. She has been able to break free of Ragyō's control, possibly because of the Life Fibers implanted into her body.
 * Life Fiber Restoration -  Ragyō was also capable of recreating Harime Nui's arms by sewing new Life Fibers into them. Although she noted they were not as good as her original ones.
 * Flight - Much like her daughters, Ragyō is capable of flying at high speeds, although she does not require the use of a Kamui to do so.
 * Life Fiber Swords -  During the battle against her daughters, Ragyō wielded a pair of giant, sewing needle-like swords, which acording to her were made from ultra-hardened Life Fibers produced by the Original Life Fiber, that can sever Life Fibers and which served as the basis for the development of the Bakuzan and Scissor Blades. She also demonstrated the ability to alter their form, shaping them into a pair of spiked, tree branch-like blades.
 * Shinra-Kōketsu (神羅纐纈)
 * Life Fiber Domination (人衣君臨) - Shinra-Kouketsu does not not seem to undergo any sort of transformation after being put on or "activated", and its current capabilities are unknown.

Former Powers and Abilities

 * Kamui Junketsu (神衣純潔)
 * Life Fiber Override (人衣圧倒) - After donning Junketsu, Ragyō is able to activate Life Fiber Override, transforming the Kamui into a variation of Satsuki's Life Fiber Override form and increasing Ragyō's strength exponentionally. Unlike her daughter Satsuki, Ragyō is able to draw out the Kamui's full power, as she herself is a being who's merged with the Life Fibers. With the full power of Junketsu, Ragyō was able to easily move behind Ryūko, stab her through her chest with her bare hand and pull out her heart (despite Ryūko using True Life Fiber Synchronise at the time).
