Royal Enforcement Division

Introduction
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 but the members don't bear the surname of Zahard. For example: [Ren]] bears the surname of Bia. It's unknown if they're considered the chosen sons and daughters of Zahard or if there's such a thing as "informal adoption" or "formal adoption". The only exception is that none of them have received the powers of Zahard, unlike the Princesses who also belong to the Zahard Family.

However, the RED does receive the protection of the King(Ch. 56: 2F - Submerged Fish (5)), in exchange for upholding the Zahard Family name.

The division has an infamous reputation in the Tower and even among the Zahard Family, as Ren was called "an assassin of the Zahard Family" (Ch 71).

Symbol used by the RED
Members of the division bear a crest similar to that of the Crimson Three Eyes seen on the right. Like any symbol used by an army division, this is probably separate and distinctive from the Zahard symbol depicted on items the Princesses wear.

However, the crest may or may not be also named the Crest of the Crimson Three Eyes.

It is possible the RED members receive the items bearing the RED symbol from the Commander, instead of the King.

Hierarchy and structure
The Enforcement Division has independent ranks and a command hierarchy. It's possible only the top ranks are appointed by the King while the rest of the members are recruited. Ren showed intention of recruiting Baam(ch 54) when he'd become a Ranker but this was before the boy was revealed as an Irregular.

Also, the members probably undergo security clearance(background check), given the secrecy level of certain missions.

Known ranks: Commander, Vice commander(there might be more than just 1).

Ren is No. 67 of the division and the youngest in terms of rank. This implies there're likely 67 ranks.

Loyalty to the King
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.

In addition, they join to further their personal agenda or their Family's ambitions. For example: Ren attempted to place Androssi into a predicament so she would lose some favour with the King while the Princess of the Bia Family would benefit if he succeeded in gaining proof of Androssi's "misdeeds". Many or all of the members will do anything to fulfill their agendas and to gain favour with the King, so it's likely they will attempt to complete the mission. So, their loyalty doesn't matter.

The only thing the members have in common is that they are all in awe of the power of Zahard.

Their scope of authority
Note #1: Since the Palace isn't a military installation or a place under military command and the RED isn't the actual Military Police unit, their authority likely doesn't extend to Palace personnel like courtiers, cooks, etc or to the Zahard army officers.

Note #2: If there is any crime committed by a Princess involving anyone who isn't from the Zahard Family, it's possible there could be a joint investigation consisting of RED members and another party like a Princess, the civilian Police or another authority.

Note #3: Like all military officers, it's possible the senior Princesses may be tasked with briefing the new Princess on the Rules, acceptable conduct and so on.

Note #4: The Princesses all are entitled to a personal Guide who also serves as bodyguard. Their role is to try and keep their behaviour in line and possibly, report their misdeeds to the King.

Note #5: Like all military officers, a Princess might be entitled to certain rights while she's being investigated.

The RED uphold the applicable Laws binding the Princess and enforce discipline of the Princess in terms of acceptable conduct within and outside of the Palace.

This includes duties a Princess might be tasked with, who she may or may not associate with, her interactions with and in front of the general populace, the Rules governing all Princesses, the 13 Month Series rules governing a formal Princess who has accepted 1, etc.

They have the authority to conduct surveillance of a Princess' behavior, to act on their suspicions(possibly permission from a superior is required), to investigate the reasons behind her breach of rules and collect evidence(circumstantial, concrete) of her misdeeds. The RED member also has the authority to ignore a Princess' offenses, should he have valid reasons for doing so(ch 70).

They're also allowed to forge credidentials or relevant documents, in order to impersonate someone, as part of an investigation. Example: Ren impersonated Yuga, the teacher of the wave controller class. Of course, he chose a more indirect impersonation to try and avoid raising suspicions.

Take note that like all military personnel, a Princess likely has to obtain permission from a higher authority like an older Princess or most likely, the King if she wants to take an extended leave. If she hasn’t reported back to the Palace for a certain amount of time, hasn’t made any contact with anyone and all attempts to contact her Pocket fail, this can be viewed as Absence Without Official Leave(AWOL) and it means she has gone missing or rather, deserted from the Zahard Family. And when the King finds out, he then issues an order to the RED which then tasks a member with finding the reasons behind her disappearance.

It is possible they may guard and escort a Princess who has been declared a criminal and also, provide field support for a Princess on certain missions. They probably have the authority to execute a Princess as well.

Internal investigations
Laws upholding the RED and their conduct are currently unknown.

If a RED member breaks a certain law, it's possible the RED is expected to conduct an internal investigation.

It's unknown if the RED is required by law to appoint external people when conducting an internal investigation or if someone else steps in to conduct an investigation.

But like most MP, the RED members are likely expected to police themselves to some extent and to report any breach of rules or conduct to the superiors or the higher-ups. That itself is asking for abuse as most people tend to be self-preservative and will refrain from reporting their mistakes and abuses, for fear of being punished or losing their position of power, etc.

And if the higher-ups are involved in certain abuse of power, they might be compelled to selectively investigate only members who are unconnected to their abuses. This is for fear of being uncovered should the King or a Princess. This mentality applies as well to RED members who witnessed or caught another RED member breaching said rules because they might not want to create trouble for themselves.

And since they serve the King, it's possible they might restrain parts of their behaviour, should he take special interest in a certain mission.

However, it's highly unlikely the RED

both intentional and in good faith that the member was acting in the name of "justice". In addition, the members might think they can do no wrong. Or if they're making a series of errors

Presence in general
It's unknown how much of a public presence they have, though the RED is quite infamous within the Tower(Ch 68).

This is the first scenario in terms of their public presence(as in spokesman): releasing statements for news reports or for news channels or giving out statements to the general public. They might also create memos or documents for internal circulation within the RED and parts of the Zahard empire(define and put elsewhere) and so on.

Depending on the secrecy of the mission, the spokesman might be unnamed and their rank kept secret. They might be named but their rank is unknown. Or their name and rank are both revealed.

And the amount and nature of information they release to the public will depend on sensitivity of certain political issues, if the rumour mill in the public forces their hand, if the classified status is lifted, etc.

And sometimes, the leader or one of the top ranks of the RED might make a few comments, in order to clarify the situation.

This is the second scenario. They're publicly unknown and the job of revealing any information is left to the Princesses or a third party. But this is unlikely since in many situations, most of the parties involved will issue individual statements or joint statements.

Relations with the Princesses
Feelings between the RED and Princesses aren't always that great. They're not always on great terms and their relationship is similar to relations between "military police vs officials".

Due to the nature of the RED's duties, it tends to spark resentment, annoyance, etc. in the Princess.

Nobody likes to be under surveillance. It interferes with her mission or duties and prevents them from operating with efficiency and delays her schedule. Depending on how much the Princess is under watch, she might even have to restrict some of her activities in the case some of her movements tip the RED member off.

The Princess also has to be on her best behaviour and hope that none of her previous misdeeds have been uncovered. Depending on her ability to manipulate or her connections and so on, she might be able to cover up some of her deeds.

Third, the RED member can raise false allegations as long as he gathers enough evidence to support his claims and to construct a possible misdeed. As long as the King decides to accept the evidence,

Forth, there is a lot of resentment between the RED and a former Princess because she knows the RED member will be using proof of her misdeeds and material gathered from his investigation to further his own career, agenda and likely, even his Family's Princess. At the same time, her feeling is one of hatred and pure resentment. "Why are you getting away scot-free for your own misdeeds while I can't?"

The RED also views the Princesses with some annoyance because she might try to obstruct their investigation by destroying evidence, interfering with their activities, planting false information that embarrasses the RED member and his unit in front of his superiors or the King, twisting his words in front of the King, managing to prove he's obstructing her duties by, etc.

Orders and Missions
Take note that the King issues an order to the RED which in turn, reviews his order and related information. A mission is then issued to a RED member. Over time, the scope of that mission might be revised and even expanded, like how police investigations eventually evolve. For example: if the target is revealed to have played just a minor role in a certain offense and another target is the responsible party.

For certain orders, the King doesn't care who completes them and how they were carried out. His only concern is the end result and the King was said to be "very happy" with Yuri Zahard, who retrieved the Green April 5 years ago(Ch 80). If there're any abuses of power, he might ignore them or give off a warning or impose light punishment since the importance of his order far outweighs many of these abuses.

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(Ch 72).

Below is an example of a mission(Ren's mission on 2nd Floor):
