False Rankers (부정 등록자) are hunters who are able to control the amount of mana they output, allowing them to conceal their true abilities and receive a lower rank than they should. As mentioned in the story, the big problem with false rankers is that most of them are heartless psychopaths who kill other hunters for fun. Fortunately, they are said to be quite rare.
