The physics lecture was a grueling display of high-level thermodynamics and quantum mechanics. The professor, a man who clearly enjoyed the sound of his own chalk against the board, had filled three panels with a derivation so complex it looked like ancient runes.
Most of the boys in the room had already given up; some were snoring, while others stared blankly at their notebooks as if they were written in a dead language. Even the high-tier devils were struggling. Rias and Akeno were stuck on the third line of the derivation, their brows furrowed in confusion. Even Sona and Tsubaki, the academic geniuses of the student council, were barely keeping up, their pens moving slowly as they tried to parse the logic.
Meanwhile, Alex was staring out the window, his chin resting on his hand, watching a sparrow on a nearby branch.
"Alexander-san," the professor said, his voice sharp. He was clearly annoyed by Alex's lack of focus. "Since the outside world is so much more interesting than my lecture, perhaps you can provide the final solution to this equation? Or at least tell me where we lost you?"
Alexander's Inner Voice:
[Internal Thought: Ciel, this guy is using a 19th-century approximation for a multi-variable tensor. It's cute. In Avalon, we taught this to toddlers before they learned to walk.]
[Ciel: "Indeed, darling. Shall I provide the simplified solution, or the one that proves the professor's entire thesis is slightly flawed?"]
Without even turning his head toward the board, Alex spoke in a calm, bored tone.
"The final constant is $1.67 \times 10^{-27}$, assuming you're accounting for the relativistic mass increase in the third quadrant of the vector field," Alex said.
The room went deathly silent. The professor's chalk snapped in his hand. He looked at his own notes—the answer he hadn't even reached yet—and then back at Alex.
"That... that is correct," the professor stammered. "But how? You haven't even looked at the board once!"
Alex finally turned, giving a lazy, half-smirk. He stood up and walked to the board. "Your derivation on line five is unnecessarily long. If you apply the Runcandel-Ciel transform," he said, using a name he just made up for his own logic, "you can bypass the complexity."
He grabbed a piece of chalk and, with a few swift motions, rewrote the entire middle section of the problem, streamlining the math into a beautiful, logical flow that even the non-geniuses could suddenly understand.
The Reaction:
Sona Sitri: (Her eyes wide behind her glasses) 'He just solved a PhD-level problem in his head while staring at a bird? My pride as the top student is... actually, I don't care. That was incredibly hot.'Rias Gremory:'His mind is as sharp as his blades. Is there anything this man can't do?'Akeno: (Licking her lips) "A genius Monarch... how wonderful."
Alexander's Inner Voice:
[Internal Thought: I should probably dial it back. Sona looks like she wants to marry me just for my math skills now. But then again, a King shouldn't hide his wisdom just because others are slow.]
"Good job, Alexander-san," the professor whispered, looking at the board as if it were a holy relic. "Please... take your seat."
As Alex sat back down, he caught Sona's gaze. She was blushing, her heart racing not just from the complexity of the physics, but from the raw, effortless brilliance of the man sitting just a few feet away.
