The Cursed Series

Synopsis

If you hate someone to the point of death, visit the sorcerer Kai. In exchange for just ten years of your life, he will grant you your wish... Kai's consultation room is in a certain building, but the elevator that leads to his room is usually just a dead-end wall, and only people with "negative emotions" who hate people or wish to kill them can see the guide board and elevator door. As an exception, they can also be seen by lucky people who have a strong desire to meet Kai...
