The Royal Guard or Royal Knight Corps consists of only 100 soldiers. However, in spite of this its strength is far beyond that of the three corps.
Their strength was legendary. Many of the members were world travelers and the empire actually encouraged their participation in the military since they were often individuals that were able to gain strength rapidly. The 100 soldiers were each bestowed Legendary Class Equipment by the emperor himself, except for Royal Knight No. 1 who has received God Class Equipment.
They guard and receive their orders directly from the Emperor himself.
