Satsuki Kiryūin

"Fear is freedom! Control is release! Contradiction is truth! That is the reality of this world! Listen well, you pigs in human clothing, and submit to that reality!"

- Satsuki Addressing the students of Honnōji Academy

Satsuki Kiryūin (鬼龍院 皐月) is one of the main characters in Kill la Kill. She is the president of Honnōji Academy's Student Council, and rules over the surrounding land. She has absolute authority over the academy, and is regarded with reverence by many of its residents. She is the main antagonist of the series until Episode 17, being replaced by Ragyō Kiryūin.

Personality
A very prideful woman who rules with an iron fist, she is extremely intelligent and calculating. Unlike Ryūko, she had no shame in wearing her Kamui in its most revealing form, instead describing her actions in donning Junketsu as "utterly pure". She describes people as "pigs in human clothing", and justifies that the weak and foolish must be ruled. However, she respects those with resolve and has been quite forgiving to the Elite Four. She also went out of her way to stop Ryūko when she went berserk, instead stopping Nui and allowing Mako to calm Ryūko down, congratulating her afterwards. Satsuki also seems to be aware of knowledge regarding the circumstances of Isshin Matoi's death, as shown when she demonstrated interest in Ryūko's Scissor Blade, among other instance.

Though she looks like a heartless person, it was seen in episode 16 that she also has a good heart even in childhood and has always been kind to Mitsuzo Soroi, her butler. She also treats the Elite Four as equals and works hard to ensure they are properly prepared before a fight. This even extends to her enemies as Satsuki is quite willing to spare her foes life if it is the better choice.

 * Satsuki es aceptado como el más poderoso luchador de la Academia con la fuerza física sobrehumana, velocidad, resistencia y reflejos. Su auto-escuela media era capaz de emitir un espíritu de lucha capaz de derribar 500 hombres, y ella fue capaz de incapacitar a Ira Gamagōri a pesar de su tamaño superior, la edad y con él se lleva una armadura de acero. Incluso cuando completamente desnudo, y con sus manos refrenado, todavía tenía la suficiente habilidad y el poder para matar a varios CUBIERTAS usando nada más que sus dos uñas alteradas. Ella también es muy inteligente y manipuladora como se ve por su plan para acabar con su madre y las distintas personas que ella engaña y manipula en el proceso.

Former Powers and Abilities

 * Kamui Junketsu (神衣純潔)
 * Life Fiber Override (人衣圧倒)
 * After her first clash with Ryūko, Satsuki donned the Kamui Junketsu and was able to force the blood-thirsty uniform to bow to her will. Her utter lack of shame at her appearance also allowed her to immediately attain Junketsu's Life Fiber Override and true form. Under Junketsu's power, Satsuki is granted incredible power, and even the smallest of attacks are capable of causing exceptional devastation. She is also capable of altering her Kamui's shape, as seen when she altered one of her shoulder guards into a drill to attack Ryūko. However, due to her inability to overcome the human race's resistance to the Life Fibers, she is unable to fully synchronize with her Junketsu, thus being shy of it's full power and capabilities, while exerting greater pressure and fatigue on her body.


 * Satsuki loses Junketsu after being defeated by Ragyo and imprisoned.

Ryūko Matoi
Satsuki appears moderately surprised when Ryūko brings up the latter's father's death; and with the Scissor Blade that Ryūko claims is the other half of the full weapon and demands to find the owner of that other half. Satsuki discloses little other than the speculation that there might have been involvement on her behalf. It should be noted however that Satsuki has shown no real desire to do Ryūko serious harm, even when she is left broken and defeated at her feet she is shown to have covered her with a blanket and left at least one piece of Senketsu with her. Satsuki seems to regard her as a useful tool help her achieve her goals, any other emotions towards her have yet to be seen. It is revealed in episode 18 that Ryuko is actually Satsuki's younger sister.

Junketsu
While Satsuki has never been seen communicating with Junketsu, her initial encounter with him and the fact that she has to override him in order to transform show that, unlike Ryūko with Senketsu, she has to actually bend Junketsu to her will through sheer willpower. In episode 16, Junketsu starts getting agitated after being worn by Satsuki in Override mode for a too long, prompting Shirō Iori to administer a Life Fiber inhibitor, allowing Satsuki to transform him to his normal state. This left her extremely tired.

Nui Harime
Satsuki is extremely cautious around Nui, as she seems to have some knowledge of her power. However, she still maintains her strong and impassive front when addressing her. They have known each other for an unknown amount of time.

Ragyō Kiryūin
Ragyō Kiryūin is Satsuki's mother. Little is known about her personality. However, as seen on anime, Ragyō often wears elaborate gowns made from Life Fibers and is not one to be without an extravagant entrance. It is revealed in Episode 16 that Ragyo and Satsuki have a less than pleasant relationship. Ragyo sees her daughter as little more than an heir to COVERS and is revealed to have been sexually abusing her daughter for some time now. In episode 18, Ragyō notes, how despite her daughter's impressives acheivements of wearing a Kamui and double-crossing her, she was ultimately a dissapointment due to being unable to draw out Junketsu's full power eventually defeating her and taking the Kamui for herself.

Nonon Jakuzure
Nonon first met Satsuki in kindergarten. Although Nonon didn't think much of Satsuki at first, Nonon became awestruck with Satsuki after Satsuki's sudden personality shift from happy and bubbly to serious and stone cold (due to Satsuki's father, Sōichirō Kiryūin, telling Satsuki the awful truth about Life Fibers and Satsuki's mother, Ragyō Kiryūin). From then on Nonon has pledged her undying loyalty and friendship to Satsuki. While it's apparent that Satsuki respects Nonon, it's unclear whether Satsuki shares the same level of closeness to Nonon, as Satsuki seems to regard all of her compatriots equally.

Mitsuzō Soroi
Soroi has served as Satsuki's personal butler ever since her childhood, and as such they developed a strong bond. While professional obligations are very clearly estblished, Satsuki shows great respect and consideration for Soroi, even pretending to like his tea (which in fact she finds way too bitter) so as not to offend him.

Senketsu
When Ryūko falls victim to Ragyō's brainwashing and wears Junketsu, Satsuki wears Senketsu in an attempt to stop them. She asks for Senketsu to lend her his power, even if he hates her. Apart from that, she does not seem to have any significant feelings for him, either friendly or hostile.
