Cimc is a mouse that lies all the time. He makes lying so natural, but also he will try to cheat and lie about things that are obviously false to everyone. He thinks very highly of himself and feels that he is never supposed to lose so always makes fun of people if they're beating him and will often just say that he's winning even if he is not. Cimc can often annoy many people, but he is the leader of the liars. He longs to one day find the Land of the Liars, so that he can feel free to lie as much as he wants, and be accepted for doing so.
