She resides in the Sacred Precinct with Crow-(also known as "The Sanctuary"), where Jiro and Kotaro previously stayed at when Kotaro was just a baby. She was sad to see him go, so Kotaro consoled her by saying he will write letters to her when he reaches the Special Zone. Despite her quiet demeanor, she apparently has a short temper and while she enjoys Kotaro's company, if Kotaro does something that angers her-(such as when he accidentally sneezed on the scarf that she had made for him), the Dark Princess does not hesitate to hurt him. Her powers are great enough to warp and change the weather surrounding her. Little is seen of this vampire. He is very skilled with a sword and refers to Jiro as his pupil. He is also a guardian of the Dark Princess of the North. Also known as Pile Killer Zhang or Chief Zhang. He used to be a vampire hunter, and is now a close ally of Sei. He now works for the president of the Order Coffin Company and is also considered to be one of the leaders in the Special Zone. He mentioned that it is an unwritten rule that the bloodline of the sage should not be messed with. Despite his old age, Zhang still holds enough power to kill a Kowloon child with nothing more than a wooden spike. A vampire that tries to enter the Special Zone. She and a group of vampires tried to enter the Special Zone in hope of a better life. However, she is the only one in the group to successfully enter the Special Zone in the end, though deeply traumatized by the loss of all her friends and her surrogate daughter. After the Kowloon children start attacking the Special Zone, Kelly aids the residents in defense of the area. A vampire girl that was born from the blood of Kelly Wong. Chan's mother begged Kelly to give Chan some of her blood so Chan could live because at the time Chan was very ill. Later Chan was bitten by a Kowloon child and controlled by Johan Tsang. In the end, Chan was killed by Kelly in order to stop her from being under Johan's control, as Chan was stopping Jiro from saving Kotaro, and she died in Kelly's arms. A Kowloon child that hid his identity while staying with Kelly Wong's group.
