Arbiters

The four rules
1. Arbiters cannot quit making judgements, for that is the reason why they exist.

2. Arbiters cannot experience death, for that would bring them too close to being human.

3. Arbiters cannot feel emotion, for they are dummies.

The fourth rule was added in by Oculus after seeing Decim judge Black-haired Woman.

4. Arbiters may not work hand in hand with life, for that will ruin them.

Appearances
Arbiters can generally be male or female and can come in different shapes, sizes, and appearances. However, all of them appear to be inclined to wear uniforms. The uniforms mainly consist of a pair of black pants with black dress shoes and a matching black vest with a plain button up dress white shirt underneath and a red bow tie. All of the ariters also have eyes with cross like pupils.

Job
Their job is to be given two humans who have died at the same time and judge them by having them play the game then place extreme conditions and lead the customers into thinking that they are still alive and that if they lose the game they will die. The arbiters prevent the customers from leaving and pass judgement on the customers by making the games extreme and seeing how the customers react when they believe they will die; in essence, they draw out the darkness in human hearts and pass judgement.

Existence
Their existence remains a mystery. Nona has stated that they are not human, do not experience emotions like humans do, and have never lived or died. They are even made to look like humans but are created for the specific purpose of judging humans. However, Decim appears to be an exception as Nona has implanted human emotions in him which, though at the beginning did not yet seem to appear or were not yet tapped, appear to be surfacing with him as Chiyuki criticizes him for drawing the darkness of human hearts and passing judgement, stating that it is not right for them to be doing that since humans are more simple than the arbiters think. They are usually commanded by those higher up than them.

Bars
There are several floors in the building the arbiters work and each seems to contain a bar that one arbiter works. It seems only one arbiter is allowed though assistants, whether human or animal, seem allowed. The bars vary in style depending on who the owner is but all include elevators that link the bar to outside and a hallway with bathrooms. There is also a game-board that is used to select the game for the customers to play and what appears to be an extra room where the game is played. The floor for the extra room is equipped with a motorized platform to bring about what game the customers will play. The floor can also change depending on what game they are playing, possibly linking to other dimensions through the use of a remote control which is also used to manipulate the games.

Abilities
Each arbiter seems to possess their own set of unique supernatural powers most likely used to keep rowdy or disobedient customers in line. They vary though all arbiters are expected to know how to deal with alcohol and how to operate the bar to create games. They also receive the memories of the dead as a tool for judging them, though they can request for the memories to be sent to their assistants.
