Perfect (MHA x OC)

1) Perfection (Just Keep Smiling)

"Welcome to general chemistry. I am Miss Hira."

Seika introduced herself to the class. She had spent that morning ensuring everything about her first day was going to be perfect. The blouse and skirt she had on had been ironed and laid out the night before to prevent even the slightest wrinkling. Her shoes had been bought and broken in a week prior. The lesson plans sitting in a pile on her very organized desk ranged at least into summer break.

Then a week before she had set up her room. The desks had been arranged in the perfect balance for both individual and group work. Students could sit close enough together to talk when necessary, but not so close that they were tempted to have a conversation during lessons. The walls were mostly blank, with a few equations and periodic tables spread around. Open white walls encouraged thinking, and there was less to be distracted by.

Everything was perfectly planned out.

Even the speech she was giving the class on herself now. It had been carefully written out and practiced to memorization, each sentence and word engraved into her mind. She had even worked on her smile and face in the mirror for optimal accuracy.

Her posture was straight

Her makeup was clean and simple.

Her long brown hair was cleanly back in a bun.

She was perfect as she flicked through each word.

"Do not hear the word 'general' and think that this is a coarse you can blow off and expect a good grade in. The pace in this class is extremely vigorous, and I will not slow down for any student who is not putting in the expected study time outside of class," she spoke confidently, having already given this speak three times earlier. "You are some of the top hero students in the country. And chemistry is extremely important to heros."

The class stared back at her with various expressions. Some looked unamused, leaning back into their chairs, no doubt having heard something similar to this in every class so far today. Others already had notes and pens out. Those would undoubtedly be the few to raise to the top. One student in particular though, looked as if he would rather be anywhere else than that room.

He raised a pale hand. His hair was a bright blonde and spiked all over the place, with piercing red eyes. A scowl was etched onto his face.

Seika remembered reading his chart. His middle school had sung his praises, claiming that he was a prodigy. But his entrance exam film had shown his tendency to be selfish and hotheaded.

"Yes, Bakugo?" she said, pointing to him.

Katsuki Bakugo gave her a questionable look, obviously not expecting her to have already known his name. Seika had spent hours looking into each individual student, memorizing their names, quirks, and studying their entrance exams. She needed to know everything, and plan out how each class would go.

That had been particularly how she had planned out the seating arrangement of the class. Students who showed to be loud and ravenous during the practical exam had been buffered by those who used their quirks stealthily. It wasn't a sure method, but a start to the perfect seating chart.

"What would we possibly need chemistry for as pro heros?" he asked, his voice completely monotone.

Seika smiled and let out a small laugh. It was better to act as if his comment was actually funny. Not like it was completely unnecessary and idiotic. People liked someone who was able to take a joke. So she would take the joke.

She could show him how important chemistry was.

"Your quirk uses nitroglycerin, correct?" she asked him, earning a small nod. He didn't even seem to notice that she had studied his quirk. "And why is nitroglycerin necessary for your quirk to work?"

"I sweat it. And then I can light it on fire so it explodes," he shrugged, seeming uninterested. "I can tell you about my quirk all day, but this conversation seems pointless."

Seika smiled again, hoping it was covering up her intense dislike of this student. Her hands balled up into fists behind her back. "Nitroglycerin explodes because of it has an excess of nitrogen and oxygen in its chemical formula. That allows for a combustion reaction," she explained, ensuring that her tone remained steady and cheery.

Not an emotion showed on her face that she didn't meticulously plan out in her mind before hand. She had to be in control of every moment, every feeling. Small giggles and smiles showed that she was human, and someone the students could relate to. Pushing away feelings of discontent and resentment were normal. Her dislike and frustration with bratty students would break that image, so it must be concealed at all times.

So a smile danced on her face as she continued on, explaining the properties of nitroglycerin, and why that chemical could become dangerous on the battlefield.

"Now say you were in a search and rescue mission. And the person you are trying to save is in a burning building," Seika continued. "You may not be the best hero for that mission. If your sweat came into direct contact with the flames, you could make the situation entirely worse. Harming the victim or yourself."

Bakugo tilted his head, clearly thinking about her words. Other students in the class also raised their eyebrows, seeming to have never thought about their quirks like that. Some students had other powers that caused secretion of other chemicals.

"Whatever. I'm not going to be some lame search and rescue hero anyways," the blonde decided, leaning back into his chair. Seika felt a small victory of him acknowledging his quirks danger. He half closed his eyes and tilted his head back.

"The best pro's do whatever is asked of them," Seika responded.

That was truth. Sometimes missions became extremely dangerous, but sometimes they were just plain gross. She crinkled up her nose remembering a time during her side kick work when a sewer line broke over the lair of their target. They had to fight with literal waste all around them. There had also been plenty of times when her team was sent to deal with public riot control, or saving bystanders from rubble. Hero's did the job that the people needed them to, no matter how much they didn't want to.

She clapped her hands together, moving towards the board. "If you look here," she said, pointing to an area in the board that had words written out in chalk, "you'll find my email. Feel free to ask questions anytime. Or to find me during school."

Her heels clacked on the floor as she walked to the far corner of her desk, picking up a stack of papers. She passed them out, one to each student.

"I'd like you to use the remaining time in class to fill out these papers on yourselves. I'm your teacher, but I'd also like to get to know each one of you individually. Place it on my desk as you leave."

With that, she sat back down at her desk, already reworking the room to be more perfect.
