Imperial Guardians

The Imperial Guardians (帝国皇帝近衛騎士団) are a group of powerful individuals within the Eastern Empire's Military. They serve dual roles as both a private protection force for the Emperor as well as elite agents sent to deal with important tasks.

Background
The Guardians were originally founded as a way to sort out the best of the best that the empire's military had to offer, with each of its members being as strong as an Enlightened at the bare minimum. It's members were awarded the highest honors that the nation had to offer, even being given the official title of "Royal Knight" (近衛騎士) and authority equivalent to at least a Colonel when interacting with the army as well as the authority to arrest nobles. Each and every one of its members was kitted out with Legend-Grade Gear, with mythical God-Grade equipment being given out to the Marshal and their Three Commanders. Each member of the Guardians competed against each other in duels on the regular, with its members being sorted in numerical order from strongest to weakest. The strongest among them were called Double 00's (ひとけた数字) in reference to their numerical rankings being 001-009. To become a Double 00 one had to make a request directly to the emperor and a special duel would be conducted with him as the witness. Among the Guardians there were those assigned to special jobs depending on certain factors. The first in the sequence was said to automatically be chosen as the Marshal whenever a new version of the Emperor was coronated, numbers 003-006 were assigned to guard the emperor and were known as the Four Horsemen, and members ranking between 007-020 were chosen by a committee consisting of the Emperor, the Marshal, and Gadra to serve as the Three Generals of the Guardians.

After the coronation of the latest Emperor, as well as the losses they suffered during their last war, major reform was given towards the guardians. Due to Guy Crimson winning the game set up between him and the Emperor, their strength became less important and the restrictions for becoming a member were somewhat loosened. The numerical ranking system and the hundred-member limit were similarly removed. Now they mainly serve as elite-forces stationed in each of the empire's cities, working in groups of three to protect the citizens from powerful threats.
