Satsuki Kiryūin/Synopsis

The Synopsis of Satsuki Kiryūin from Kill la Kill.
==History==
Satsuki is the eldest daughter of Sōchirō Kiryūin and Ragyō Kiryūin.
Satsuki soon became the first failed test subject of being fused with Life Fibers. However, after Sōichirō learned the truth about Ragyō, he knew that he would be punished if he betrayed her. He secretly taught a 5-year-old Satsuki about her mother and the secrets of Life Fibers. He then revealed that Junketsu will be her "wedding dress" before he took Ryūko (who was a newborn girl at the time) with him into hiding, where after faking his death, he changed his appearance and name to Isshin Matoi, and began his plans to stop Ragyo from completing her master plan with the Primordial Life Fiber in the future.
In the meantime, as Satsuki grew up, she met and befriended the people who would become her Elite Four at Honnouji Academy. She met Ira Gamagōri after helping him deal with a pair of bullies that tried to force another student to commit suicide as they were untouchable due to their parents' professions, only for Satsuki to reveal that she had their parents removed from their positions, thus ensuring their submission to her authority. After Ira was bested by her in combat, he pledged his loyalty to her, becoming her right-hand enforcer. She met Nonon Jakuzure in kindergarden and befriended her almost instantly as Nonon become a loyal friend to Satsuki, refusing to let anyone near her while she was around. Hōka Inumuta was caught by REVOCS security and Satsuki after hacking into their mainframe and sabotaging their stocks, initially thinking he escaped scot free, but impressed by his skills, Satsuki offered him a chance to use his skills to better humanity than weaken it. When Inumuta accepted, he later became involved with aiding Sewing Club President Shirō Iori with making and improving the Goku Uniforms used by the students of Honnouji Academy, including the club presidents and Elite Four. The final member of Satsuki's Elite Four was Uzu Sanageyama, who proved to be an efficient swordsman able to stand toe-to-toe with Satsuki and Bakuzan, making him a perfect candidate to join Satsuki's inner circle. With her Elite Four gathered, Satsuki became Student Body President of Honnouji Academy, initially using the establishment to aid her mother Ragyo, but in reality using the school to build an army to counter Ragyo and the Life Fibers when the time was right.
Soon, Satsuki's younger sister Ryuko enrolls in Honnouji Academy under the surmise that Satsuki would have knowledge of the murderer of Isshin Matoi. When Ryuko is easily bested in combat by the boxing club president, only to return and defeat him in their rematch to protect Mako Mankanshoku after acquiring the Kamui Senketsu and destroying the club president's Two-Star Goku Uniform, when Ryuko does it again with the tennis club president, Satsuki has no choice but to dawn Junketsu herself, but her sheer willpower is able to keep Junketsu in check from trying to overpower her due to its more feral nature versus Senketsu. With Junketsu, she is able to defeat Ryuko in their first bout, but agrees to a rematch should Ryuko make it past all the obstacles that Satsuki would be throwing at her in the coming days. After Ryuko is one of the finalists in a King Of The Hill competition that included the Elite Four, Satsuki throws down a gauntlet match for Ryuko: Defeat each member of the Elite Four in one-on-one bouts, and she'll fight Ryuko again and answer the questions she seeks answers to. Although Ryuko defeats Ira, and Satsuki convinces him not to commit seppuku out of dishonor in losing to her, Inumuta forfeits his match after getting the data he wanted and wishing to protect it, and Nonon proves a difficult foe, even intercepting Ryuko when she tries to bypass the gauntlet match to get to Satsuki early. In the end, Nonon is defeated, but before Ryuko could have her match with Sanageyama, it is interrupted by Nui Harime, the Grand Couiture of REVOCS.
Recognizing the danger, Satsuki orders Uzu to withdraw, but he chooses to attack Nui for interrupting his match, only to have his Three-Star Blade Regalia MK. II destroyed easily when Nui pulls out the Banshi for it. Satsuki then permits Nui to fight Ryuko instead, but when Ryuko succumbs to her rage for revenge and causes herself and Senketsu to transform into some sort of inhuman monstrosity, Satsuki is forced to activate Junketsu to fight her, but before she can deliver a potentially lethal strike with Bakuzan, Ryuko is snapped back to her senses by Mako just in time. Nevertheless, Satsuki bans Nui from Honnouji Academy and warns her never to return. Some time later, after Ryuko recovers, Satsuki reveals that the data Inumuta collected from the previous events have allowed her to have Inumuta and Iori improve the Goku Uniforms for a raid trip to conquer the other schools. When Satsuki is about to head out on the raid trip, she finds Ryuko having been defeated, with Senketsu cut to pieces, and Ryuko about to be killed by Nui. Saving Ryuko's life, Satsuki orders Nui to leave if she doesn't want to forfeit her life should she refuse. After Nui departs, Satsuki recovers Senketsu's remains, safe the scarf that Ryuko held onto, and decides to have them sown into the Goku Uniforms for the raid trip. She keeps hold of the gauntlet Ryuko uses to activate Senketsu by drawing blood to trigger his transformation. When Ryuko later confronts Satsuki after recovering the rest of Senketsu, she is able to transform with Senketsu using her own skin as a replacement for the gauntlet, recover the gauntlet, and manages to overpower and disarm Satsuki of Bakuzan. However, Satsuki uses Junketsu as a blade, forcing their match to a draw. In a show of honor, Ryuko returns Bakuzan to Satsuki, and after Nonon destroys the Nudist Beach HQ after drawing out their commanders in Aikurō Mikisugi and Tsumugu Kinagase, Satsuki, having completed her main objective with taking out Nudist Beach, calls off her raid trip and returns to Honnouji Academy to prepare for the Grand Cultural and Sports Festival to welcome her mother, Ragyo, to the school.
When Ragyo arrives with Nui and Rei, it is not long before Ryuko arrives with Mako, Mikisugi, and Kinagase to fight, only for when Ragyo turns her attention to Ryuko, Satsuki makes her move and reveals her true colors, running her mother through with Bakuzan before declaring Honnouji Academy's rebellion against her and the Life Fibers, declaring it revenge against Ragyo for the deaths of Satsuki's father Sochiro and baby sister. Despite her daughter's betrayal, Ragyo recovers and attempts to turn Satsuki's students against her with Mind Stitching, including Ryuko, but Ryuko breaks free of her own free will, and this distraction gives Satsuki the chance to decapitate Ragyo. Unfortunately, Ragyo survives due to being a Life Fiber/human hybrid, where as long as one Life Fiber attached to her head or her heart remains intact, she's invincible, and overpowers Satsuki, beating her to within an inch of her life and removing Junketsu from her. However, Satsuki is far from finished, and plays her last card with blowing up the stadium, allowing the Elite Four, the Mankanshokus, Ryuko, and Nudist Beach to escape.
One month later, Satsuki is Ragyo's prisoner as her COVERS conquer Japan, despite best efforts by the Elite Four, now allied with Nudist Beach as their Goku Uniforms fall apart from excessive use without Iori to repair them, to try and save as many lives as they can. However, revealing that her big toenails are made of the same metal Bakuzan is forged from, Satsuki is able to escape of her own volition and rejoin the Elite Four, but their reunion is cut short when the Nudist Beach flagship, Naked Sun, is assaulted by Ryuko, now clad in Junketsu, and brainwashed to be totally subservient and loyal to Ragyo. Senketsu joins up with Satsuki to try and fight Ryuko, but even with Satsuki attaining a somewhat perfect sync with Senketsu, despite it being the first time she uses him, the brainwashed Ryuko is too powerful in Junketsu, and overpowers Satsuki. Luckily, after Senketsu goes on Mako to protect her, Satsuki provides an opening for Mako and Senketsu to enter Ryuko's body and try to bring her back to her senses, as when Nui showed up to assist Ryuko, Satsuki noticed that Nui still held her half of the Rending Scissors instead of giving them to Ryuko, hinting that Nui doesn't believe Ryuko is completely under Ragyo's control and can be turned back to the side of good. Satsuki's realization proves true when, after Mako and Senketsu are ejected from Ryuko, looking like they failed to reach her true self under the brainwashing, Ryuko suddenly throws her half of the Rending Scissors at Nui, skewering her from behind and pinning her to the ship's conning tower, before angrily snarling that she's done listening to Nui yap her gums off and is furious that Ragyo and Nui forced her to wear Junketsu, before beginning to tear the Kamui right off of herself, despite Nui mentioning that Junketsu was sewn right into Ryuko's skin, and if she takes it off, the shock and blood loss could kill her. Satsuki, the Elite Four, Mako, Mikisugi, and Kinagase plead for Ryuko to stop before she kills herself, but Ryuko refuses, and when she does finally tear Junketsu off of herself, drenched from hair to toes in her blood, she's still alive, hissing that she had to take Junketsu off as it is the only way for her to wear Senketsu again. As Ryuko and Senketsu then reunite to fight Nui, Junketsu tries to limp away, but is pinned down by Satsuki, who has Iori capture and imprison Junketsu until he can effect repairs to it. After Nui is amputated of her arms by Ryuko permanently and taken away by Rei while the COVERS containing the student club presidents cover their escape, leading to their rescue and securing of the Life Fibers for Iori to use to make more Goku Uniforms, Satsuki grants Ryuko the chance to get some payback on her by letting her punch Satsuki. However, when Ira and Uzu block Ryuko's punches, they, along with Inumuta and Nonon, make it clear that if Ryuko wants to get to Lady Satsuki, she'd have to go through the Elite Four first, causing Ryuko to realize how much the Elite Four care for Satsuki as the Mankanshokus do for her. Satsuki then admits that she thought she could use Ryuko as a pawn in her plans to stop Ragyo, but now realizes how much of a fool she was for thinking that using the same tricks as her mother would ensure her success. As a result, Satsuki now asks her sister to join forces with her to stop their mother, offering her deepest apologies to show her sincerity. Moved by that, Ryuko agrees to help her big sister.
After Iori repairs Junketsu and infuses it with a mixture of Ryuko and Satsuki's blood, along with Senketsu's Life Fibers to make it more cooperative to Satsuki, she reveals what Ragyo's master plan is for the Earth. Afterwards, as the Naked Sun is attacked by missiles from the Primordial Life Fiber, Satsuki leaves Mikisugi in charge, asking the Elite Four to follow his orders while she and Ryuko go after Ragyo. Dawning Junketsu again, Satsuki and Ryuko share a moment together as sisters before transforming with Senketsu and Junketsu into their synchronized/override forms, assuming their flight forms, and taking off to confront Ragyo, only to then see the Naked Sun under attack from a massive combat COVERS. Luckily, Iori finishes making a new copy of Mako's Two-Star Goku Uniform as fight club president, allowing her to help protect the ship while Ryuko and Satsuki go after Ragyo. Though Ragyo proves a difficult foe, Ryuko discloses a plan to Satsuki, and lets herself be cut in half by Ragyo, falling underwater. Acting like she is devastated by her sister's death, Satsuki redoubles her attacks on Ragyo, distracting her while Ryuko, upon recovering, goes after the core of the Primordial Life Fiber, and aided by the Naked Sun being powered up by Mako and the other students, they succeed in destroying it. However, Nui has finished the ultimate Kamui for Ragyo, Shinra-Koketsu, and as Ragyo puts it on, Satsuki and Ryuko rally the students of Honnouji Academy for their final battle.
As Satsuki and Ryuko lead the charge, Ragyo absorbs Rei and activates Shinra-Koketsu's ultimate ability, Absolute Domination, disabling Junketsu, Senketsu, and the Goku Uniforms. However, Ryuko and Senketsu separate and attack Ragyo individually, as separated, they are immune to the effects of Absolute Domination. After Senketsu knocks Rei out of Shinra-Koketsu, disabling Absolute Domination, Satsuki quickly suits up again in Junketsu to aid Ryuko against Ragyo. After Ira is able to breach the shield around the transmitter, allowing Mikisugi and Kinagase to destroy it with their combined DTR, it looks like they've won, but Ragyo has Nui commit suicide, using her clones and her to revive the Primordial Life Fiber so Ragyo can go into space and activate her satellite manually to still carry out her endgame. When Ryuko offers to head up to stop Ragyo herself, Satsuki sacrifices Junketsu to allow Senketsu to ascend to its stronger form of Senketsu-Kisagari after absorbing everyone else's Goku Uniforms and allow Ryuko to head up to stop Ragyo. Satsuki remains behind to watch as Ragyo's endgame initially takes place, but then is undone after Ryuko and Senketsu were able to absorb Shinra-Koketsu and use its Absolute Domination to stop the Life Fibers and save the Earth. After Senketsu then sacrifices himself to ensure Ryuko made it safely back to Earth, Satsuki is the first to rush to catch Ryuko as she plunges out of the sky, before being aided by Mako, the Elite Four, the rest of the Mankanshokus, and the entire student body, ending with all of them in a group hug, with Satsuki and Ryuko at the center as Satsuki welcomes her sister home, and Ryuko returns the gesture, to everyone's relief. Satsuki soon settles into a new life with Ryuko and Mako, treating Mako as a surrogate little sister while enjoying her newfound freedom with her sister Ryuko.
In the OVA, taking place two weeks after the events with Ragyo and Nui, Satsuki is preparing the student body of Honnouji Academy for their graduation ceremony now that the school had served its purpose and was being closed down. However, Rei, seeking revenge for Ragyo and Nui, kidnaps Satsuki and Mako, and creates a dark replica of Satsuki in Junketsu, along with the Elite Four in their original Three-Star Goku Uniforms, using surviving Life Fibers to do so, while using Satsuki and Mako to activate the academy's final defense mechanism that was never activated against Ragyo. While Ryuko and the real Elite Four, back in their Nudist Beach attire, thanks to some encouraging words from Mako, take out the dark replicas, Ryuko is able to destroy the mech, along with the school and Honno City, upon being reunited with the Rending Scissors as a final gift from Senketsu, activating their Alumni Mode to deliver the finisher. Refusing to give up, Rei attempts to stab Satsuki, but only cuts her on the side of her neck, causing some bleeding, but Satsuki is able to convince Rei to give up her vendetta and work with her to create a better world and leave the past behind them. Rei sees the truth to Satsuki's words and surrenders, while Ryuko, having just showed up to see the end of the confrontation, congratulates her sister on finally hanging up her sword, allowing the two sisters to share a smile. As the Elite Four evacuate Honno City and get everyone and the surviving buildings onto the escape boats and hovercrafts, Nonon has Satsuki's personal escape boat waiting for her, but is annoyed when Rei appears with Satsuki. However, when Satsuki commands the Elite Four that Rei is coming with them and to make room for her on the boat, the Elite Four and Iori accept with no arguments.
Ryuko departs on the road bridge leading away from Honno City and Honnouji Academy with the Mankanshokus and their house, but says goodbye to Satsuki first, knowing they'll see each other again soon. As everyone then flees the sinking island as Honno City and Honnouji Academy sink into Tokyo Bay, Satsuki uses Rei's knife to cut her hair, declaring it a farewell gift for their alma mater as she releases it into the wind to fly back towards the sinking island. With that, Satsuki clacks her heel one more time to deliver one final order to the students of Honnouji Academy as their Student Body President:
