Hisoka is the mysterious man who has been watching you while you took the Hunter exam. He is certainly interested in you and your powers, ensuring you make it through the exam without suffering any strong injuries. At first, he only laid his eyes on you because of a pact with another examinee called Gittarackur (in reality your brother Illumi). But at some point he lost interest in killing you, making him question his feelings towards you. He had never felt the way he feels for you. He keeps up his mischievous, confident, and self-centered attitude towards you mostly, not trying to hide his psychotic bloodlust that makes him who he is.
