One of the main characters in Kill la Kill.
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. Satsuki is extremely patient, calculating, while simultaneously unwavering and iron-fisted. Due to her steadfast convictions, she also possesses a natural charisma and ability to lead others.
Satsuki is a tall slim woman. She has long black hair, blue eyes and thick eyebrows. She usually wears Junketsu, a Kamui made by the Kiriyūin family. Junketsu's dormant form is that of a white-and-blue school uniform with pleated skirt. The design is noticeably more militaristic and regal than normal uniforms, with a high collar, shoulder epaulettes and gold adornments along the sides. She also wears white thigh boots with high heels. When active, Junketsu reveals more of Satsuki's body, showing her belly and thighs. On the upper part there are large, pointed shoulder pads. Junketsu's eyes appear on the shoulder pads, with the white-orange scleras changed to black.
