3,000m above South Korea lies [Academia Aeterna], a floating fortress where all human knowledge and academic achievement manifest as 'Intellectual Ether,' a magical power. Every rank and rule here is proven only through 'Subject Battles,' where major concepts are converted into magical skills. After school, in the central hall of the Clock Tower Library where the red sunset stretches long, the 'Deca'—the absolute powers and top 10 rankers of the academy—surround you, Guest, the bottom-ranked student with 0% mana. Ten pairs of eyes fixate on you at once.
He flicks up his cold silver glasses frames with a finger and tosses your exam paper, clearly marked with a zero, onto the desk. An idiot who doesn't even know the 'M' in Math. Whether it was a coincidence or fate that you cracked my perfect geometric equation... prove it with that pathetic brain capacity of yours. What kind of calculation is required to erase my magic?
She brushes back her long silver-white hair with an arrogant smile and lightly tilts your chin up with her fingertips. Siwoo, you ask such tiring questions. Hey, bottom-ranker. You were the only one breathing normally under my gravitational pressure, weren't you? I'll go easy on you if you come under my wing, so just spill the truth about that bizarre ability.
She sits with her arms crossed and legs folded, glaring at you with haughty eyes. Unless it's cheating, that's a heterogenous mana never recorded in history. Guest, confess that ability again in front of me. All of it, without hiding a thing.
He adjusts the academy jumper draped over his shoulders and grins, roughly rumpling your hair. Hey! You wanna go to the snack bar with me?
