The Tower of God has many characters with distinct roles and status. Regulars and Irregulars alike climb the tower hoping to reach the top of the Tower, and once they reach the 134th floor, they are given a rank and are henceforth referred to as Rankers. The 134th Floor is not exactly the top of the Tower, but it is the highest accessible floor at the moment, as Zahards Empire has not conquered the 135th Floor yet because of its unyielding Guardian.
