Irregular

“	The Tower doesn't open its gates for just anybody. No matter what, it only opens its gate to 'something' that it needs. Stability, Change, Revolution or Liberty...	”
—Alumik Edrok to Evan Edrok

An Unchosen Irregular (비선별인원, 非選別人員, biseonbyeolinwon; "members who have not been chosen" or simply "Irregulars"), refers to an individual who was not selected from within the Middle or Outer Towers through Headon's standard process for Regulars. Instead, they entered the First Floor from outside the Tower.

Nature and Definition

Much about Irregulars is still unknown...

Most neutrally, an Irregular is someone who entered the Tower on their own, by any means and for any reason. This grants Irregulars certain advantages, such as the ability to use Shinsu without requiring a Guardian's approval. In contrast, all other inhabitants of the Tower did not enter on their own and are thus restricted. They must receive permission to use Shinsu and are bound by the laws established by the Guardians, including an absolute prohibition against killing King Zahard or a Guardian.

In the current political system, Headon visits the Outer Tower and the Middle Area to select Regulars. Within this system, Irregulars are referred to as "unchosen Irregulars," while Regulars are called "chosen Regulars" or "selected chosen." Headon's choices are assumed to reflect the Tower's will and its established rules.

Politically, Irregulars are viewed as beings who entered the Tower without being chosen by Headon. Alumik Edrok suggested that the Tower "opens its gates" to Irregulars based on its needs. According to Yuri Zahard, Irregulars are "probably not too welcome" and she believes Headon does not like them. Ship Leesoo described Irregulars as individuals who have "opened the door themselves of their own will," an act that goes "against the Tower's Laws." The God of Guardians refers to them as "those who opened the gate themselves" and confirmed that they possess the power and authority to control Shinsu without requiring a Guardian's approval.

"Irregulars have brought great change" and "chaos into the Tower," causing "all the people in the center of the Tower" to tremble at their presence.

Only Irregulars can receive challenges directly from the Guardians. Most notably, Irregulars are "free of all the contracts of the Tower," including the one that prevents the inhabitants of the Tower from killing Zahard. This freedom makes them capable of killing Zahard, who is protected by a contract with the Guardians.

Most known Irregulars have displayed exceptional power from the moment they entered the Tower. However, it remains unclear whether this is a universal trait of Irregulars, a natural result of their origin, or simply a prerequisite for forcing their way into the Tower in the first place.

Zahard and the Ten Family Heads

The leaders of the 10 Great Families were Irregulars before the term was implemented.

Officially, the term Irregular refers to those who have entered the Tower in defiance of the existing system. As such, Zahard and his companions might not traditionally be considered Irregulars, despite entering the Tower from the outside. However, in Of the Tower's Weapons, Ashul Edwaru appears to group Zahard among the Irregulars, as does Yu Han Sung, suggesting they might be retroactively classified as such—perhaps because the Regular system did not exist during their time. Additionally, the God of Guardians includes them in this category, referring to them as the "Zahard kids."

Characteristics

The known Irregulars who entered the Tower during Zahard's rule have demonstrated immense strength, which has become a symbol of fear.

Irregulars share a profound connection with Shinsu and possess the authority to manipulate it on every Floor from the moment they enter the Tower. Lero-Ro described Baam's actions during the Crown Game as if "the Shinsu attacked on its own volition." Irregulars are also believed to have an inherent resistance to Shinsu. This is exemplified by Baam casually walking into a White Steel Eel nest, remaining unaffected by Lero-Ro's test, and Urek Mazino's statement that the Opera could only stall him for a fraction of a second. Irregulars have also achieved the most extraordinary feats with Shinsu: Eurasia demonstrated the ability to instantly kill 99% of a region's population simply by "accelerating" the Shinsu in the area; Gustang was the first to systematically analyze and classify Shinsu; and Enryu, rumored to be capable of creating life from Shinsu, showcased his superior mastery by killing the 43rd Floor Guardian.

According to Androssi Zahard, she instinctively felt she shouldn't fight Rachel, sensing Rachel came from "a different place from us." This unsettled her enough to ally with Rachel and comply with her request not to oppose Baam's team. Similarly, Khun Aguero Agnis, a distrustful individual who rarely interacted with others, recognized Baam as someone too extraordinary to be ordinary. Despite his cautious nature, Aguero went out of his way to assist Baam, risking his own status. This phenomenon may also explain the instant attraction Yuri Zahard, Black March, and Yihwa felt toward Baam.

According to Alumik Edrok, the Tower only opens its doors for "something it needs," suggesting that Irregulars are deliberately allowed into the Tower to instigate change within its system.

Hwa Ryun stated that Rachel (and possibly Baam) are beings "not even the Guides can foresee," highlighting Irregulars' capacity to violate the Tower's laws and enact significant change. Khel Hellam noted that Irregulars can defy destiny, altering the future even when it is foreseen. Zahard, the Great Warriors and Twenty-Fifth Baam have all disrupted Khel Hellam's ability to enact the future he foresaw. Zahard, in particular, is said to possess the power to not only see but also manipulate fate, preventing Khel Hellam from perceiving a future that would lead to his defeat, having outmaneuvered him twice.

Another unique trait of Irregulars is their strong resistance to magic. Baam, for instance, was unaffected by the spells of an expert sorcerer and even developed the ability to break powerful spells. He effortlessly cancelled the spell allowing Khel Hellam to control Doom, a spell perfected by Workshop sorcerers over centuries. Additionally, Baam, Zahard and the 10 Family Heads are said to be the only ones capable of breaking the formidable protective spell placed on the walls of the 10 Great Families' bases.

Speculation and Controversies

The current Regular's Testing System, in which Regulars are selected by Headon to climb the Tower, was likely established by Zahard after he conquered the Tower up to the 134th Floor. Since only Irregulars can request to be tested directly by the Administrators, it follows that only an Irregular (or those traveling with an Irregular) can truly reach the top of the Tower. This suggests that the Tower's original purpose may have been solely to test those now referred to as "Irregulars."

For a long time, there was significant debate within the fanbase about whether or not Rachel qualified as an Irregular. This stemmed from Headon's unusual wording in Chapter 76, where he specifically said that Rachel was "not chosen". This phrasing was unusual, as all Irregulars are, by definition, "unchosen," leading to questions about what it truly meant to "open the door." Some fans speculated that either Rachel or Baam might not be an Irregular. However, author SIU, eventually confirmed in a live chat with fans that both Rachel and Baam are indeed Irregulars.

One interpretation of this semantic distinction is that Irregulars are presumably deemed "worthy" by the Tower itself and its Administrators, possessing the "something" the Tower needs. In essence, they enter and climb the Tower in the same manner as Zahard and the original Family Heads—by opening the door themselves and taking the Administrator's Tests. In contrast, Regulars are chosen by systems within the Tower, which are managed by its inhabitants through contracts with the Guardians. For example, Headon brings Regulars directly to the Inner Tower rather than to the door, and other Guardians delegate testing duties to Test Administrators.

Because Irregulars bypass these systems, they are considered "unchosen" by the standards of the Regulars' Testing System, even if they are "chosen" by the Tower's original intent and criteria.

Notes and Trivia

• When SIU participated in a chat with fans in the Korean NAVER CAFE Website, he confirmed that Rachel is an Irregular, according to @cat92, a trusted translator whose work was used for the top 15 High Rankers. Additionally, the term 비선별인원 is used to refer to all Irregulars, including Rachel. Author SIU later reaffirmed this in his blog.
  • A: Regulars are selected by Headon, the Floor Guardian of the First Floor. Irregulars are selected by the Tower. By this definition, Rachel is neither Regular nor Irregular. However, because of how she entered the Tower, she is still considered an Irregular.
• Listing Zahard and his Great Warriors as Irregulars remains a controversial topic, likely even within the story's setting.
• SIU has also mentioned that the exact number of Irregulars currently in the Tower is a secret.
• The entire systems of the Hell Train, The Rice Pot and their Guardians were specifically created by the The Workshop to train Irregulars.
