Ragyō Kiryūin

"Behold the fate of all who defy me - no, who defy the Life Fibers!"

- Ragyō gloats after defeating Satsuki and taking Junketsu for herself. "La vie est drôle... Life is indeed amusing."

- Ragyo Kiryuin

Ragyō Kiryūin is the main antagonist of the 2013 anime Kill La Kill, and the CEO of the Revocs Corporation, a facade textile company whose true goal was to assist the COVERS in the circulation of Life Fibers worldwide along with Nui Harime and Rei Hōōmaru. She is the most evil character in Kill La Kill and all of Hiroyuki Imaishi's works.

She was voiced by Romi Park in the Japanese dubbed version, and Laura Post in the English dubbed version.

Appearance
Ragyō's most prominent feature is her resplendent multicolored hair shown under while the rest is a silver white color. She also has seven scars on her back that greatly resemble the stars emblazoned in Goku Uniforms. The origin of these scars is unknown, but they are likely a result of her fusion with Life Fibers. Since the number of stars on Goku Uniforms indicates the percentage of Life Fibers in them, this might imply that Ragyo's body is now composed of 70% Life Fibers.

Normally, she wears white clothing, consisting of a long dress, high heels, and a large feathered boa. She is also adorned with a metal belt and choker.

Personality
After Ragyō gave up her human side to the Life Fibers, she became a power-hungry and cold-hearted shell of her human self. As such, she is very traitorous, sadistic, unsympathetic, ruthless, and destructive, callously toying with and manipulating other human beings for the sake of her deranged beliefs. When in battle, Ragyō is especially aggressive, uncaring, and merciless, especially towards her enemies, and especially with her own daughters when they turned against her. However, she enjoys domination and control, lusting for power over the world in order to give it to the Life Fibers. She also has an unnervingly domineering and perverse side, as she showed off her unhealthy obsession with power by molesting both her daughters frequently. She also has great intelligence, adding on to her sophisticated personality and diva-esque exterior, as she knows her fair share of science and technology all throughout her life. She is also treacherous, deceptive, and manipulative, particularly able to deceive most of the people into buying highly transformative Life Fiber- infused clothing.

History
Raygo first discovered the Original Life Fiber and decided to use it dominate humanity. She later married a scientist, Soichiro, to have access to his skills. Ragyo placed her first-born daughter and then second newborn daughter into an experiment where their DNA will be infused with Life Fibers. However, both were conceived failures, with the latter child being disposed of soon after.

Soichiro vowed to to secretly escape with his second daughter, who had changed his name to Isshin Matoi. He raised his daughter, Ryuko, and founded the Nudist Beach to combat the Life Fibers. During this time, he created the Kamui Senketsu. At the same time, Ragyo raised Satsuki to be her successor, during which she repeatedly molested her daughter. Using the Life Fibers, she created Nui Harime to be the Grand Couturier of the Revocs Corporation. She then began selling Life Fiber-infused clothing around the world.

Ragyo located Isshin Matoi and sent Nui to kill him and steal his latest invention, the Scissor Blade, which Nui succeeded to retrieve one side of the Scissor Blade, with Ryuko gaining possession of the other half. Seeking vengeance for her father's death, Ryuko enrolled at Honnouji Academy, which Satsuki was the student council president of. During this time, Ragyo gifted Satsuki with Junketsu, a Kamui.

She later attended the Great Culture and Sport Festival, but this turned out to be part of a ploy to sacrifice those attending to the Life Fibers. Ryuko and Nudist Beach arrived to free those held captive. Ragyo was then betrayed by Satsuki and the Student Council, who later sided with Nudist Beach. Satsuki revealed that she had been secretly working against Ragyo from a young age, after her father had revealed Ragyo's true intentions to her. However, Ragyo brainwashed the student body to turn on Satsuki, who managed to overcome them. Satsuki then managed to confront her mother personally. However, despite wearing a Kamui, Satsuki was no match for her mother, who brutally beat her and stripped her of Junketsu. Taking Junketsu for herself, Ragyo then ambushed Ryuko and tore out her heart, revealing that Ryuko was Ragyo's daughter. Nudist Beach rescued Ryuko and brought her to safety while Ragyo unleashed the Life Fibers onto civilization.

Ragyo captured Satsuki and kept her caged for a month, molesting her constantly. During this time, she had Nui construct Shinra Koketsu, the ultimate Kamui. She lured Ryuko to Honnouji Academy and captured her, brainwashing her and grafting Junketsu onto her body. After Satsuki escaped and joined Nudist Beach, Ragyo sent Ryuko and Nui to kill them; however at that point, Ryuko's brainwashing gets severed, and she was separated from Junketsu. The Nudist Beach then prepared for the final battle against Ragyo.

Ragyo unleashed the Primordial Life Fiber and engaged her daughters in battle. Eventually, Nudist Beach apparently succeeded in destroying the Primordial Life Fiber with the second form of the S.S. Naked Sun. However, Ragyo continued the battle wearing Shinra Koketsu, with the Pirmordial Life Fiber having survived destruction. Upon being injured, Ragyo absorbed Nui and flew out into space, planning to activate the Revocs Communication Satellite and send the signal to cover the planet in Life Fibers. Ryuko pursued her into space and battled her mother, and ultimately managed to destroy the Life Fibers, returning Ragyo to human form.

With the threat to enslave humanity over, Ryuko asked Ragyo to return to Earth. However, Ragyo rejected reconciliation and crushed her heart, commiting suicide. Before vanishing into space, Ragyo warned Ryuko that the Life Fibers would return to Earth.
