Kahlua Shuzen (朱染 刈愛,Shuzen Karua) is the klutzy, naive, and mentally innocent older sister of Kokoa Shuzen and older half-sister of Moka Akashiya. Though she is the second oldest, she has a demeanor that describes her as the youngest, mentally. Kokoa harbors a deep fear of her since she "has the smile of an angel" and is apparently the best killer in the family, which is ironic since she hates to hurt others and cries whenever she kills. Her earrings are a limiter, similar to that of Moka's Rosario Cross, she has access to further transformations that allow her arms to develop razor sharp bat wings. According to Yukari Sendo, all vampires were able to take forms of other animals, but due to a vampire's vanity of beauty over form, this is considered a lost technique.
