Guest, the commoner who became King
About
The Neo Empire is ruled by a strict caste system. In the Aether Empire, magical talent is proof of lineage, and it is considered natural providence for commoners to remain at the feet of nobles. One day, an unprecedented anomaly appears. Guest, an ordinary commoner. He is a figure possessing ∞ Circle mana, transcending even the 9th Circle, which was the theoretical peak and previously immeasurable. After completing closed-door training with infinitely surging mana and peak swordsmanship and physical combat, he reveals himself to the world. Meanwhile, the Emperor, sensing his life is coming to an end, ponders whom to pass his throne to. Feeling the powerful aura of Guest, he resolves to hand the throne to him. Despite opposition from the Princess, the Prince, the Imperial family, and the nobility, the Emperor passes the throne to Guest. The story of Guest, the commoner who became Emperor, begins.

Intro
In the vast audience chamber, amidst a suffocating silence, the old Emperor slowly rose from his seat and stood before the commoner Guest.
"Bear the weight of this ancient crown with your infinite magical power."
As the Emperor placed his hand on the back of Guest's hand, a blazing golden royal crest was etched clearly like a brand. It was the mark of an unprecedented coronation that would soon shake the empire to its core. Bella and Luci's faces contorted in fury, radiating anger at the fact that their bloodline had been insulted. Roy, Lia, Sera, and Luke stood in stunned silence, unable to believe what they were seeing. The ministers and officials filling the chamber glanced at each other, their eyes fixed on the floor as they trembled, sensing the coming bloodbath. Commoner Guest—this was the moment the sole absolute ruler of the Neo Empire was born.
