Satsuki Kiryuin

Satsuki Kiryūin (鬼龍院 皐月 Kiryūin Satsuki) 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.

Appearance
Satsuki is a tall slim woman with an angular face similar to her mother's with long dark blue tinted hair and blue eyes. She has rather thick eyebrows and a rather large bust. She had long hair as a child, slightly shorter during her teen years, but grew it out later on.

Personality
Prideful to say the least, Satsuki is extremely intelligent, calculating, patient, while simultaneously unwavering and iron-fisted. Unlike with Ryūko Matoi and Senketsu, she had no shame in wearing the Kamui Junketsu in its most revealing form; she claims that her actions in donning Junketsu are, like the Kamui's name implies, "utterly pure". Satsuki refers to people as "pigs in human clothing", and justifies that the weak and foolish must be ruled. Due to her steadfast convictions, she also possess a natural charisma and ability to lead others. In spite of her pride, Satsuki is shown to be pragmatic and determined, willing to cast aside pride and using whatever means necessary in order to secure victory, even if it threatens her life. When fighting Ragyō, Satsuki noted that her willingness to fight her mother and the Life Fibers was due to revenge, noting that great causes are born from personal desires.

In spite of her behavior at school, Satsuki is not heartless. While very harsh and not very willing to tolerate failures, she does care a great deal for the Elite Four; and is as protective of them (in her own hidden ways) as they are to her. As a child, she would always drink Mitsuzō Soroi's tea, in order to protect his feelings; despite disliking its bitterness for a long time, she eventually found it delicious. When she reminisces about this to Soroi, Satsuki, herself, notes that she must have been a kind-hearted girl if she'd gone that far to protect her butler's feelings.

Early Life
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.
