Senketsu (鮮血 lit. fresh blood?) is a Kamui created by Isshin Matoi who is later revealed to be Sōichirō Kiryūin, and is the deuteragonist of Kill la Kill. Appearing as a sentient sailor uniform, he was found by his creator's daughter, Ryūko Matoi, becoming her primary ally in her battle against Satsuki Kiryūin and, later, Ragyō Kiryūin and COVERS. Senketsu appears to be a navy-blue and red sailor suit with the midriff shown and a lower-cut skirt. When Senketsu is on his own, the section between the shirt and skirt resembles a mouth, in that he is attached to his lower jaw at the back. When he is worn, however, the skirt is connected to the upper body by three suspenders. He speaks to Ryūko with a deep male voice and everyone refers to him with male pronouns, even though Kamui are technically agender entities. In most circumstances, Senketsu is a composed and analytical individual, calmly observing and assessing situations as they occur. He maintains this level-headedness even in the heat of battle, thinking of attack strategies, giving Ryūko advice and warning her whenever she is about to run out of energy. He initially shows a manic and aggressive craving for Ryūko's blood, as he needs it to remain active, although this is satiated once she starts wearing him regularly. Despite being an article of clothing, Senketsu is shown to have undeniably humanistic qualities, such as genuine and even fatherly love of Ryūko, crying when getting sentimental and feeling lonely whenever Ryūko is not wearing him, which is accentuated by the fact that only she can hear his voice. Senketsu is horrified of being washed by hand, as it is quite painful for him. However, he is fond of being ironed, which he finds soothing.
