Satsuki Kiryūin

Satsuki Kiryūin (鬼龍院 皐月) is the main antagonist 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.

Personality
Said to rule with an iron fist, she is extremely intelligent and calculating. Unlike Ryūko, she had no shame in wearing an absurdly revealing dress when she wore Junketsu, instead describing her actions in donning the Kamui 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 Ryuko when she went berserk, instead stopping Nui and allowing Mako to calm Ryuko 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 instances.

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.


 * Secret Sword Bakuzan (秘剣縛斬)
 * In battle, Satsuki wields the Bakuzan, a black-bladed katana in a white sheath with an edge that is claimed to be keener than Ryūko's Scissor Blade. Its strength is so great that one slash is enough to damage a transformed Kamui. Satsuki is highly proficient in using it.
 * Natural capabilities
 * Satsuki is accepted as the most powerful fighter of the Academy. Her middle-school self was able to emit a fighting spirit capable of downing 500 men, and she was able to incapacitate Ira Gamagōri despite him wearing steel armor.

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 Ryuko 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.

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 what appear to be wedding dresses as casual clothing.
