Ectoplasm's enormous white teeth gleamed as he wrote another incomprehensible equation that took up the entire surface.
"And, therefore," Ectoplasm announced in his deep, resonant voice as he pointed at the formula, "the derivative of this function gives us the rate of change at any given point on the curve."
Izuku stared at the board with empty eyes.
Why does calculus even exist? he thought desperately. Who decided that letters needed to mix with numbers?
Beside him, Ochako was doodling little scribbles in the margins of her notebook. A tiny cat, a flower, something that might've been a hamburger.
At least I'm not the only one suffering, Izuku noted with a bit of relief.
But then his eyes drifted forward, where Momo and Iida were sitting in the front row. Both of them had their backs straight, their notebooks open and their pens flying across the page as they transcribed every word coming out of Ectoplasm's mouth.
Momo's hand glided over the page, occasionally stopping to underline something or add a margin note. Her gray eyes followed the teacher's movements with absolute concentration.
Iida nodded vigorously at every explanation, raising his fist now and then in a sign of approval.
Of course they're enjoying this, Izuku thought with resignation. Momo probably dreams about equations, and Iida probably has a special notebook just for math formulas organized by difficulty level.
"Now then," Ectoplasm continued as he created a clone that appeared beside the board in a small puff of smoke, "let's examine a practical application of this concept in hero work. Imagine you need to calculate the optimal trajectory to intercept a villain moving at variable speed..."
Izuku's brain shut down completely.
I'm gonna die here, he thought while his soul tried to escape through his ears. This is how it all ends, slowly dissolving into a puddle of mathematical suffering while Ectoplasm explains derivatives with those nightmare teeth.
Tick.
Tock.
Tick.
Tock.
Izuku looked at the clock on the wall. Only five minutes had passed since the last time he checked it.
Five minutes, he thought, horrified. I've aged ten years and only five minutes have gone by.
RIIIIIIING!
YES! Izuku shouted internally as he gathered his things at full speed. FREEDOM! SWEET, BEAUTIFUL FREEDOM!
He stuffed his notebook into his backpack with such enthusiasm that he almost tore it. Ochako stood up beside him with a sigh of relief, stretching her arms above her head.
"I thought that class was never gonna end," she whispered as they headed for the door.
"You and me both," Izuku replied in an equally low tone.
They walked together down the hallway while the rest of Class 1-A scattered in different directions.
"Izuku-kun," Ochako said suddenly, leaning slightly toward him, "is it just me, or does Professor Ectoplasm give you the creeps?"
Izuku blinked.
"The creeps?"
"I dunno how to explain it," Ochako continued while hugging her backpack against her chest. "He's a good teacher and all, but... I feel like if he wasn't teaching at U.A., he'd be the final boss in some video game or something."
Izuku processed her words for a moment.
Now that she mentions it...
He thought back to Ectoplasm's appearance: the huge white teeth that seemed too big for his mouth, the strange black mask covering his face, the way his clones appeared and disappeared in puffs of smoke.
If I saw him in a dark alley, I'd definitely run the other way, Izuku admitted internally. Just those teeth alone could give kids nightmares for weeks.
He glanced to his right, where Bakugo was walking with his frown firmly in place and his blond, spiky hair sticking up in every direction.
Wait, bad comparison: Bakugo's hair always looks like that. That's just genetics mixed with rage.
"Yeah," Izuku finally said to Ochako with a slight smile. "I get what you mean. But he's a Pro Hero, so I guess we've gotta get used to it."
"Guess so," Ochako replied, though she didn't sound entirely convinced.
Behind them, Momo caught up with quick, elegant steps. Her expression was radiant, her eyes shining with intellectual satisfaction.
"That was an excellent class!" she exclaimed enthusiastically. "Professor Ectoplasm explained the relationship between derivatives and their real world applications with great clarity. I took several pages of notes!"
Izuku and Ochako exchanged a resigned look.
My sweet, dear Momo..., Izuku thought. Who else would enjoy a math class like it was a concert from her favorite band?
"That's... great, Momo," Ochako said with a smile.
"Indeed!" Momo continued while adjusting her backpack on her shoulder. "The practical applications he mentioned will be incredibly useful for calculating the optimal timing of my Creation Quirk during combat scenarios. I need to review my notes and cross reference them with my chemistry textbook tonight."
She's actually planning to study more math voluntarily, Izuku thought, amazed. This girl is on another level; I really do admire her.
Momo's expression shifted suddenly, turning more serious as she turned to look directly at Izuku.
"Izuku-kun, we still need to run those tests regarding your Quirk."
Izuku felt his heart speed up.
OH GOD, YES.
"Right," he said, keeping his voice carefully neutral. "The documentation... scientific?"
"Exactly," Momo confirmed with a nod. "The discovery that the location of contact affects the efficiency of the Booster is significant. We need to determine if there's a pattern related to muscle mass, subcutaneous fat distribution, or some other physiological factor we haven't considered yet."
Ochako tilted her head curiously.
"Are you guys gonna train together?"
"In a way," Momo replied as she pulled a small notebook from her backpack. "I'm curious about the details of Izuku-kun's Quirk. I feel that we need to experiment more thoroughly to understand the underlying mechanisms."
Ochako's eyes lit up with understanding.
"Ah! That makes sense. Can I join too?"
YESYESYESYESYES! YEEEEEEEEES! Izuku screamed in his mind while keeping a perfectly calm exterior. That means I won't just be groping Momo, I'll get to do it with Ochako too! This is PARADISE!
"That would be perfect, Uraraka-san," Momo said with a smile. "After all, you were the first person Izuku-kun successfully used his Quirk on. Your data would provide an important comparison baseline."
"Awesome!" Ochako replied enthusiastically. "When do we start?"
"Well," Momo said while consulting her notebook, "we could start this afternoon, after Izuku-kun finishes his detention class."
Izuku's smile froze on his face.
D-detention class? I totally forgot about...
"Well, well, well."
The voice came from behind, playful and with a melodically sensual edge.
"So here's where the little rebel was hiding."
Izuku's spine went rigid and a cold sweat broke out across his forehead.
T-that sexy voice...
"For some reason," the voice continued with amused malice, "I had the feeling you'd forgotten about our date. That's very rude, Izuku-kun."
His hands clenched into fists at his sides while his breathing turned shallow, and despite his best efforts, he felt a traitorous twitch in his pants.
Hey, not now, not here, easy there! Down, Fifi!
He turned around slowly, bracing himself to face his teacher...
Nemuri Kayama stood in the hallway with one hand on her hip, radiating predatory confidence. The purple and white outfit of her hero costume clung to every curve in an erotic and alluring way. Her purple hair fell over her shoulders, and her blue eyes glittered with sadistic amusement behind her red tinted glasses.
The sexiest woman at U.A., Izuku thought appreciatively. And... the same big breasted girl who welcomed me to U.A. SHE IS... MIDNIGHT.
The R-Rated Heroine.
Hero name: Midnight. Quirk: Somnambulist. The ability to put people to sleep with her scent.
And, according to every hero database he'd ever read, she was a certified dominatrix who got off on making others squirm.
A sadistic woman, Izuku realized. Someone who proactively takes control and enjoys watching others suffer. This is veryyyyy bad... because she's the one in charge of my punishment.
He swallowed hard and forced his expression into something resembling confidence.
"Hello, Midnight-sensei," he said while straightening his posture. "How could I possibly forget our date? Of course I'd never forget. Me? Forget that I have a date with one of the most beautiful heroines in all of Musutafu? Ha! You really underestimate me, sensei."
Ochako and Momo turned to look at him with completely blank expressions.
He totally forgot, both of them thought at the exact same time.
Midnight's smile widened, revealing perfect white teeth. She took another step closer, her heels clicking against the floor in a predatory rhythm.
"Oh, really?" she purred while lifting a hand to adjust her glasses. "Because the way you're sweating right now suggests otherwise, Izuku-kun."
Am I sweating?
"And the way your voice cracked when you said 'hello' was absolutely adorable," Midnight continued while walking in circles around him. "Really, it's okay to admit you forgot. I won't punish you too harshly."
The emphasis on "too" made Izuku's survival instincts scream in terror.
That's it; this is how my pervert journey ends. Murdered by a sexy dominatrix teacher before I can even run the comparison tests with Momo and Ochako.
"I really didn't forget, sensei," Izuku insisted while trying to maintain eye contact and failing miserably, since his gaze kept dropping to her generous chest.
Hey, you can't blame me: it's way too eye catching and looks completely soft.
"I was... mentally preparing for our session together."
Nice save; she definitely bought it. Way to go, Izuku: you're a genius.
Midnight tilted her head.
"Mentally preparing?" she repeated. "That makes it sound like you're about to face a villain instead of spending quality time with your teacher."
She leaned closer, close enough for Izuku to smell her perfume.
"Tell me, Izuku-kun," she whispered conspiratorially, "are you afraid of me?"
AFRAID? OF COURSE NOT! YOU'RE LIKE EVERY WET DREAM AND NIGHTMARE WRAPPED INTO ONE DANGEROUS PACKAGE!
"Of course not, sensei," he said out loud. "I have nothing to fear from an educational detention session."
"Mhhhmmm... I like that, in any case," Midnight continued while gesturing down the hallway with one hand, "our date is now. So if you ladies will excuse us, I need to borrow your friend for the next hour."
Today is the best day of my life.
He turned to Ochako and Momo with what he hoped was a dying hero's smile while a tear of victory threatened to fall from his eye.
"I'll catch up with you guys later for the experiments, okay?"
"Good luck, Izuku-kun," Ochako said sympathetically.
"Stay strong," Momo added in a low voice.
Midnight placed a hand on Izuku's shoulder.
"Come on, get moving," she said cheerfully. "We've got a lot to talk about. And Izuku-kun?"
"Yes, sensei?"
Her smile turned predatory.
"I hope you're ready for a... very intense education."
