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".

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, a RED member fails to complete a task, it seems they can make a report to their division 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.

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)

The crest also appears on Princess Yuri Zahard, Androssi, and other symbols or agents of Zahard.
