The younger of the two twin maids in the Tohno mansion, Hisui is a childhood friend of Shiki. She wears a western maid uniform and attends to Shiki when he comes back to the Tohno mansion. Her name, Hisui, is the Japanese word for jade, referring to her eye color. ~!She acts cold and unfeeling, but it is only an act to hide her kinder nature for the sake of her sister. She is a Synchronizer, a person that can give someone life energy through the exchange of body fluids.!~ from Wikipedia entry

~!Hisui was a member of a branch family of the Fujou clan, but was brought with her sister Kohaku to live in the Tohno mansion, because the Fujou clan had a special power of giving others energy. Makihisa Tohno needed this ability in order to keep control of his body. Hisui, however, was never forced to utilize her abilities as a Synchronizer because of the pleas of Kohaku and instead found herself living as a normal girl.!~
