"Fear is freedom! Subjugation is liberation! Contradiction is truth! Those are the facts of this world! And you will all surrender to them, you pigs in human clothing!"History
Satsuki was the first-born child to Ragyō and Sōichirō Kiryūin, and 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 an infant Ryūko with him into hiding.While in kindergarten, Satsuki was friends with Nonon Jakuzure, who knew what Satsuki was thinking and decided to join her in her resolve.
During her rise to power, Satsuki helped Ira Gamagōri save a boy who was being forced into jumping off the roof of Rinne-Dō Junior High, discovered Hōka Inumuta following his hacking into the Revocs Corporation's computer systems, and was impressed with Uzu Sanageyama's fighting skills. Upon Honnōji Academy being established, she became the school president with her followers becoming the Student Council's Elite Four.
When Ryūko Matoi arrived at Honnōji Academy and bonded with Senketsu, Satsuki snuck into her mother's house and bonded with Junketsu. She then challenged Ryūko and easily defeated her, proving herself to be the more capable Kamui wearer at the time. She later decides to use Ryūko to help her rebuild Honnōji Academy's structure from the ground up by letting her destroy all the students who came in her way and thereby only leaving the strongest. After a while she takes this a step further and announces the First Naturals Election where only the most capable students would rise to the top, this being the Elite Four and Ryūko. Her plan was interrupted however, by the unexpected meddling of Nui Harime who manages to make Ryūko go berserk and be consumed by Senketsu and Satsuki has to intervene to stop the girl from destroying everything on the premises, though Mako Mankanshoku calms Ryūko down before Satsuki is able to land a finishing blow.
After this, Satsuki announces the Tri-City Schools Raid Trip to take over the Kansai region, the only area outside her control. Though in reality her real objective was to flush out Nudist Beach from hiding. The Raid Trip proves to be a success and Satsuki manages to take control of all the schools in Japan to allow Revocs Corporation to distribute it's clothing to them. She fights Ryūko again during the Raid Trip during the latter's self-appointed mission to rebuild Senketsu who had been destroyed by Nui Harime. The pieces were retrieved by Satsuki and distributed to students on the Raid Trip but Ryūko successfully managed to rebuild her Kamui, even managing to retake the Seki Tekkō from Satsuki herself.
After the attack on the S.S. Naked Sun, Satsuki allows Ryūko, still synchronized with Senketsu, to punch her, although the Elite Four protect her by standing in the way. After explaining the reasons for her actions to Ryūko, Satsuki calls herself a fool; she states that she cannot hope to win against Ragyō by employing her cruel methods—which include manipulating and using one's own family. Satsuki finally sees that the world's beauty comes not from being "cut from the same cloth", but from the innumerable, unexplained things that the world overflows with. She asks Ryūko to help her fight to protect that "beautiful world"; upon saying her part, Satsuki bows to Ryūko—a shocking sign of sincerity. Though Ryūko tries to stay angry at her, this uncharacteristic act convinces her to let her anger go.
After this, Satsuki becomes a bit more open and relatable to others. She shows this when the gang has a celebratory dinner of Sukuyo Mankanshoku's signature croquettes, when she agrees with Mako about their being delicious; and when Nonon Jakuzure and Uzu Sanageyama have an argument involving disrespect and lack of tact, telling Ira that hearing them bicker "makes it feel that I've truly come home". Satsuki displays that she is still dead-set on accomplishing the mission at hand. For example, in episode 23, she follows Ryūko's plan, distracting Ragyō while allowing Ryūko to reach the Life Fiber core unhindered. Later, she tells the Elite Four to destroy the transmitter while she and Ryūko fight Ragyō.
Later, back at Honnōji, Satsuki tells everyone there that Honnōji Academy has a month before being decommissioned as their plan against Ragyō had succeeded. During the "Honnōji Academy First Graduation Ceremony", she told Soroi to make tea for all the students to drink and thanking him for all he had done. As Soroi leaves, she planned to make a speech but was taken by a clone of herself.
After being captured by the false Satsuki, Rei Hōōmaru appears and tells her that she's getting revenge for the death of Ragyō and Nui. Rei uses Satsuki as a "first rate source for the activation of Life Fibers" for the Honnōji Academy Final Defense Apparatus. Satsuki comments that if she dies it will shut down but Rei reveals that Mako has also been captured and is also being used as a source. However, Rei was ultimately defeated thanks to Ryūko and the rest of the Academy's efforts.
Rei then returned to the captive Satsuki and Mako as they were trying to escape but Rei then lunged towards Satsuki, cutting her hair and the side of her neck. Satsuki tells Rei that she "can't imagine the hell she had lived through because people don't understand, the world needs you". Rei replied, saying that she was speaking nonsense to which Satsuki said "That's who we are." Rei drops her knife, accepting her offer. Ryūko appears and comments to Satsuki, saying that she had finally put her sword away, in which both sisters smiled at each other. They all leave the now-sinking Honnō City. During the evacuation, Satsuki uses the knife Rei dropped and cuts her hair leveled, as "a small offering to our alma mater". Satsuki then orders all students to salute to pay respect to Honnōji Academy.
