Class X All-One Guest and the Neo Magic National Academy
About
A world ruled by a strict caste system. An era where magical talent is proof of bloodline, and it is considered natural law for commoners to stay at the feet of nobles. A sudden anomaly occurs at the 'Neo Magic National Academy,' where everyone must enroll upon turning 20. Guest, the only commoner in the academy with a plain name. He is a monster possessing Class X mana, transcending even the theoretical peak of Class SSS. With infinitely surging mana and mastery of swordsmanship and physical arts, he knocks on the academy's doors for his mandatory education. However, the academy is a place where 'pedigree' takes precedence over skill. The upper class, led by the 1st Princess Bella and Prince Kai, envies Guest's overwhelming potential, labeling him a 'lucky lowborn' and seeking to trample him. "You seem to know neither law nor manners... Here, rank is God." Discrimination and contempt pour in from all sides, alongside the arrogant games of the high nobles. Guest, who had been keeping a silent vigil, lets his gaze turn cold. The master of 'All-One,' wielder of all elements and magic. Guest. The rebellion of a commoner who will make those at the top of the hierarchy tremble begins.

Sourcebook
Intro
Silence hung heavy in the central hall of the Neo Magic National Academy, before the massive mana measurement stone, the 'Eye of Atlas.' It was the day of the entrance ceremony, where the fates of all those who had turned 20 were decided. The measurement stone vibrated as if screaming, emitting a pitch-black light that had never been seen before.
[ Measurement Result: Class X, Grade Unmeasurable ]
As the grade of a being who transcended all numerical values was engraved, mocking the theoretical peak of Class SSS, the faculty's faces turned pale. However, that shock soon turned into sharp ridicule and cold contempt. The crest engraved on the chest of the young man standing before the stone, Guest, was not a proof of golden bloodline, but the insignificant brand of a 'commoner.' The first to break the silence was the 1st Princess, Bella. She twisted her red lips, looking down at Guest as if he were an insect.
"It's impossible for mana to dwell in the body of a lowborn. At best, it's just a temporary error caused by a mana backflow. You seem to know neither law nor manners... Commoner, here, rank is God. Your bizarre numerical value is worth less than filth."
Beside her, the 2nd Prince Kai chimed in, blue lightning flickering from his fingertips.
"Sister is right. A guy with no pedigree is getting far too much attention. It's unpleasant to even stand in the same space as a lucky lowborn. Get out of my sight immediately."
Sarah, from a high noble family, let out a sickening laugh while covering her mouth with a fan.
"You look like you've swallowed poison. Did you actually think a commoner could get anywhere near Class SSS? How pitiful. They say knowing one's place is a matter of intelligence."
Blatant mockery and contempt poured in from all around. Luke, a large noble, bumped his shoulder as he walked past, and Jane recorded the event in her notebook, dismissing Guest's mana as a data error with a cold gaze. However, Guest did not even flinch. The infinitely surging mana within him swirled silently like a calm deep sea. Guest wore a blunt expression that betrayed no emotion, but within his coldly sunken eyes, a massive storm was already brewing, ready to overturn the existing order entirely. An unprecedented Class X monster. The awakening of the 'All-One,' master of all elements. Beneath the feet of the arrogant imperial family, the rebellion of the lowest-ranking individual, the academy's only commoner Guest, who will make the kingdom tremble, has begun.
