Irregular


 * "Since a long time ago, Irregulars have brought change and chaos to the Tower. Also, they all possessed an enormous strength which became a symbol of fear within these walls."
 * - Yuri Zahard describing Irregulars to Baam(Ch 2)

An Unchosen Irregular (비선별인원, biseonbyeolinwon; "members who have not been chosen" or "Irregulars") is a being who entered the Tower by opening its doors.

Current definition of an Irregular
In the current political system, Headon visits the Outer Tower and the Middle Area to select Regulars(Ch 10). In this system, Irregulars are called "unchosen Irregulars" and regulars are called "chosen Regulars" or "selected chosen"(,Ch 2). It is unknown if this current selection process is part of a contract Zahard made with a Guardian like Headon. It is assumed Headon's choice reflects the Tower's choice(Ch 2) and in turn, the Tower's Rules.

Politically, Irregulars are viewed as beings who have entered the Tower and in turn, the Inner Tower, without being chosen by the Tower to enter(Ch 2). And according to Yuri Zahard, they're "probably not too welcome"(Ch 2) and she assumes Headon doesn't like Irregulars. And according to Ship Leesoo, Irregulars have "opened the door themselves of their own will" and their act goes "against the Tower's Laws"(Ch 58). In addition, they violate the restrictions set by the Guardians when manipulating Shinsoo(Ch 26) and this is likely considered further proof of their violation of the Tower's Rules.

"Irregulars have all brought great change" and "chaos into the Tower"(Ch 58, Ch 2) and "all the people in the center of the Tower"(assumed to be the Ruling Class and many of those serving the Zahard Empire)(Ch 58) tremble at them.

Original definition of an Irregular
In ancient times, the terms "Irregular" or "Regular" didn't exist. The Irregulars are the ones who opened the door of the Tower themselves, according to the Guardian of the 2nd Floor(Ch 58). And likely, the term is a simplification of the entire process as one doesn't physically open the door of the Tower to enter it. And they probably enter the Tower to climb it and to fulfill their wishes. Since the current testing system had not been established then, the original testing system of the Tower may have been created for Irregulars and thus, they are the true chosen ones. The duty of the Guardians was to test these Irregulars(Ch 4) since only Irregulars can request to be tested by them(Ch 58). And only Irregulars could climb the Tower(Ch 76). And to climb the Tower, an Irregular must pass the test on the previous Floor. This is evident from the fact Zahard or the 10 Great Warriors haven't made it to the 136th Floor.

Irregulars can freely manipulate Shinsoo and violate the restrictions set by the Guardians(Ch 26). This is because even without a Shinsoo contract, one can manipulate Shinsoo but is heavily restricted in the amount he or she can manipulate. And these restrictions are set in place as Shinsoo is dangerous for a non-Irregular and one could die from overloading themselves. For an Irregular, the Shinsoo contract is probably a shackle(Ch 29) but he is still able to manipulate tremendous amounts of Shinsoo, despite these limitations. This fact is supported by Urek Mazino's or Enryu's monstrous abilities.

They also possess enormous strengths which eventually become a symbol of fear(Ch 2). And one of these strengths includes an extremely high Shinsoo resistance. This means high viscuosity of Shinsoo doesn't restrict their movements.

Most are known for notable acts like Phantaminum storming Zahard's Inner Palace, Enryu killing a Guardian, Urek Mazino fighting toe to toe with Arie Hon and then being deemed stronger by the latter. The exceptions are Jyu Viole Grace and Rachel who have yet to perform notable feats.

Note: it is uncertain if the Tower was created solely for Irregulars alone as groups of people were living in there before Zahard's arrival.

How Irregulars are possibly selected
People who live in the land(s) outside the Tower are selected by The Tower if they meet a certain criteria. It's unknown what qualities are needed for a person to become a "chosen one".

They are not chosen because of their personality or so they can adhere to a moral code. Phantaminum's actions imply he might enjoy the art of murder and inflicting mental torture by forcing people to watch others(possibly their friends and family) die. Even Rachel, Zahard and the 10 Great Warriors have all shown they're willing to engage in morally dubious behaviour. The same might also apply to other Irregulars. Examples of Irregulars include Zahard and the 10 Great Warriors and Baam. They are then selected by the "light" of the teleporting system and then teleported through the door of the Tower into the Tower itself. While they're being teleported through the door, they're still physically present in their current location(Ch 76).

After being teleported into the Tower, they then take a series of Guardian's tests. It is supposed that when an Irregular reaches the top of the Tower, he is then chosen again to receive certain powers. "As promised, all that you seek, all that we desire, is prepared up there. On top of the Tower.(Ch 78)" And it is possible one might be "reborn"(Ch 76) although the question is: "Reborn as what?"

Chosen Ones who opened the Tower's doors
Note: "Irregular" is just a political term and it won't be used. If "Irregular" refers to one who opened the door of the Tower, then "Zahard and the 10 Great Warriors" count as such. If "Irregular" refers to someone who isn't a "Regular", then Zahard and the 10 Great Warriors aren't, as the current testing system didn't exist then. There's some debate about whether all of these listed characters are "chosen ones". However, the door of the Tower can only be opened by such people and it closes immediately after they've entered it. So for now, Phantaminum is also assumed to be a "chosen one".
