The title of Magic Emperor was originally given to honor Prince Lemiel Silvamillion Clover, the mage who defended humanity against a giant demon. Over time, the title was passed down for generations within the Clover Kingdom. It became a title that signifies the holder as the strongest mage within the Kingdom. Additionally, the holder of the title is officially recognized and acknowledged as the leader of the Kingdom's Magic Knights.
As the leader of the Clover Kingdom's Magic Knights, the Magic Emperor holds a pivotal role in the Kingdom's military affairs. Furthermore, the Magic Emperor's military authority is equal to that of the King of the Clover Kingdom.
One of the duties of the Emperor is organizing the movements and activities of the Magic Knights in their duties as the protectors of the Kingdom. This could consist of delegating missions to Knights, or personally going to the battlefield in an effort to defend the Kingdom against foreign invasions.
Achieving the title of Magic Emperor is an effort of high significance. It is because for every generation of Knights, only one mage could have the privilege of holding the title. However, the weight of the title does not translate to the exclusivity of the title to a certain group of Knights, such as those of noble birth. Every Knight within the organization has the opportunity to become the Magic Emperor.
It is because the only sole requirement that a Magic Knight must possess in order to become the Magic Emperor is merit. To be acknowledged as the strongest Knight within the Kingdom, a mage must possess a list of merits or achievements that could support it. That is the reason why the title of Magic Emperor is not an exclusive title, but part of the five ranks within the Magic Knights organization that every Knight could aim to achieve.
