Royal Enforcement Division

Name and purpose of organisation
Royal Enforcement Division or RED has a literally translated meaning of: Zahard + Royal(ty) + under direct command + punishment/enforcement + squad/division/regiment/etc which gives some hints about what they do.

This division is part of the Zahard Family and at the same time, all of their enemies are formerly from the Zahard Family. Because of this, there is some animosity between the the RED and their enemies as they're likely viewed as traitors and betrayers of the Empire. According to SIU, "it's kinda like the feelings between the military police and an official". As a result, the division is infamous even among the Zahard Family and apparently, Ren was called "an assassin of the Zahard Family" by Evan Edrok in Ch 71.

It has been noted that they may be able to recruit people for the Zahard Empire, as Ren stated that Baam might be worthy of bearing their crest.

They serve Zahard and no one else. However, the division is not loyal to him. The amount of loyalty towards Zahard among the individual members varies greatly as most of them joined the division only to fulfill their urges and lust to commit murder or to fight. The only thing the members have in common is that they are all in awe of the power of Zahard.

In the event that a RED member fails to complete a task, it seems they can make a report to their division and/or the King as long as there is evidence, as Ren states in Ch 72.

Hierarchy and structure
The Enforcement Division has independent ranks and a command hierarchy. This was evidenced by the fact that Ren was talking to his "sunbae" aka his superiors in Ch 54. He also mentioned a "Vice commander".

Ren is No. 67 of the division. His latest mission, as part of the division, was to stop Anak from climing the tower, to recover the Green April and the Black March (ch.54,55,56). And he was called a "Ranker of the Zahard Family" in Ch 56.

Symbol used by the RED and other similar symbols
Members of the division bear the crest of the Crimson Three Eyes seen on the right. Or rather, a modified version of the Zahard Crest as there is a vertical line from the middle eye and some additional curved lines, the meaning of which is unknown so far.

A symbol similar to The Crest of The Crimson Three Eyes appeares on a wall of the cave that Baam was trapped in his entire life. (Chapter 28)
