Zhang Lei Kao

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.
