K-Sha is a member of Gold Third. A student of the Lastation school for girls. She excels in both academics and sports, and rumor has it she is quite popular with the boys. Her hobbies are music appreciation and performance, and she's also skilled at rhythm games due to her quick reflexes.

K-Sha is a yandere when it comes to Noire. She's very protective and cares passionately about her, though in a somewhat romantic way which annoys Noire occasionally. This trait goes so far that initially, K-Sha wanted to kill Uni so that she would have Noire for herself. This trait also leaves her normal side to be casted away, leaving only an almost uncontrollable yandere girl. She is somewhat shy towards others.

When holding a gun however, K-Sha's personality changes drastically. Rather than being shy, she becomes dead serious and will complete her missions without question. Much like Uni, K-Sha is skilled with guns.

"This is K-Sha. I have successfully infiltrated the destination point. I will now continue the mission."
