Kikune

The last and only female member of the four virtues, a group of four elite agents, who answer to both the white king and the blue king. Kikune specializes in inventions and has shown her ingeniousness on a number of occasions. It is also hinted upon that she and Ichimatsu are attracted to each other. Kikune was given a mission up north, where she was sent to spy on the black king and report what she observed back to the white and blue kings. When up north, she had her memory sealed, and took on the identity of Kasane. It was also then that she met Sarasa, who fled up north due to the shock of learning the red king's identity. They quickly became friends, and even after Kikune realized who she was, she remained Sarasa's friend, aiding her on a number of occasions. Eventually when she learns about the relationship between shuri and sarasa, she does whatever she can to help the two of them.
