There are cases of disappearances around him. People will forget about someone, forget their name, and then their existence will be forgotten. That person will disappear. They are 'lost'. Nikk, a sixth-grader, has a father who locked him up at home after school. He despised him. He thought that there were people that should just disappear. And if there's someone that he doesn't want to disappear from the world, it's his dear friend, Rea.
