Achilles Heel

II. Her Quirk

She didn't expect to run into him like this. All [f/n] did was open the door to class 1-A, nothing more nothing less. It was because of an "Oh my god... You got to be fucking kidding me," that doomed her morning. Right? As much as she tried to tell herself that, the girl knew that she was ill-fated from the very start.

Bakugou sat lazily at a desk second column away from the door. His silent yet menacing gaze never left her trembling figure. Anxiety incapacitated her, but her mind was screaming at her to move. 'Move, move, move. It isn't safe here. You have to leave NOW.' As adrenaline pumped throughout her body, her heart rapidly papillated against her sternum. It was only a matter of time before she started to hyperventilate. Her breathing became rigid and raspy, as her hands struggled to loosen her uniform collar. Bullets perspired from every pore on her body, leaving a sickly color on her skin.

People began to pivot their attention toward the train wreck. Her hair was disheveled, clothes wrinkly and unkempt, sullen eyes, and a face drained of its color. [F/n] tried opening her mouth, though nothing came out. The only sound emitted from her was of her suffocating on air.

"Are you all right?" A boy asked. He was tall, wore glasses, and made funky gestures with his arms and hands, which reminded her of a forklift. But no response was given. Petrified, [F/n] stared at him, her eyes yearning, begging someone would come to save her.

"[F/n]!" A familiar voice rang. It was Midoriya, thank god, who managed to break the girl from her spell. She promptly spun around to be face to face with broccoli boy. His appearance was rather timid, nervous even. "[F/n], I'm sorry I didn't see your message. I overslept so I couldn't walk with you to school," the boy regrettably said.

She wanted to talk, to reassure her best friend that it was all right and that he doesn't need to guilt-trip himself into crying about it. But the mass of eyes staring at her was crippling enough to hinder her from doing so. [F/n] only nodded, mouthing 'It's all right. Can we talk in the hall?'

"Y-yea, of course." The two of them took a step outside, closing the door behind before heading off to talk privately.

"I-I can't do this, Izuku-kun. H-he scares me to death." Her words were nearly inaudible if it wasn't for the fact Midoriya had learned to lip read over the years they had spent together. "I might drop out."

Midoriya frowned, "[F/n], don't drop out! You worked so hard to get this far." Tears started to form in his eyes, "I'm here and I will suppor--" She waited for him to continue but nothing came out. He was stupefied, terrified even. Curious, [F/n] followed his gaze to see an anomaly laying on the ground behind her.

It was yellow with long black hair coming out of the hole. It took the girl a second to realize what she was looking at was someone in a sleeping bag. Slowly, a figure began to get up, and out emerged a disheveled man dressed in all black minus his grey scarf. His movements reminded her of a sloth, languid with exhaustion puppeteering every gesture he took. His sullen eyes reminded her of someone dying, or what she thought someone dying would look like. Was he all right? Or did he always look like that

"It took you eight seconds to quiet down. Time is precious," he said as he combed a hand through his hair. "I'm your homeroom teacher Aizawa Shota. A pleasure to meet you." Lazily the man proceeded to dig through his sleeping bag to pull out a gym uniform too small for his stature. "Put these on," he began, "and head to the fields behind U.A. Hurry up." As the class began to follow orders, Aizawa turned toward the two in the hallway. "You must be [L/n] [F/n]." The girl, anxious as to why he called her out, nodded. "I read your report and understand that you are selectively mute. I won't force you to do anything, but you have to know that I won't coddle you." His words were cold, though understandable since this was the best hero academy in Japan.

On the field, Aizawa explained the quirk assessment test and its eight components. Everyone was thrilled, but the idea of revealing her quirk to everyone was disconcerting.

[F/n]'s quirk wasn't helpful in a physical sense. It didn't enhance her speed, strength, flexibility. All it did was allow her to withstand high temperatures that nearly everyone couldn't handle and combust. Her quirk dealt with combustion, pyrophoricity. Unlike Endeavor who could create fire and manipulate it, [F/n]'s quirk only allowed her to set things on fire, combust, and withstand higher temperatures. You could say her quirk's like a match, able to ignite but nothing more. Able to melt, but unable to control fire. It dealt with combustion on both an internal and external level. As for combustion, it was like Bakugou's though proven to be deadlier. If she, for example, were to touch and activate her quirk on someone, not only would they burn on the outside, but also internally. However, she must be touching something, whether it'd be an object or the air around her. This was how she managed to pass the initial exam by melting the robots after touching it. There are stages to combustion that she can control. Ashes are a result of incomplete combustion. As a result, she can turn something into ashes. As for her tolerance to heat, her body temperature is higher than normal, and she can withstand blue fire. As a result, her skin is typically dry, so there is a constant need to apply lotion.

Unbeknownst to Bakugou, [F/n] was relatively strong. Since she never revealed her quirk in middle school due to its combustible nature, [F/n] hid it from the world. He didn't understand how someone so weak-minded was able to withstand against his explosive quirk. All the boy knew was that she refused to reveal it. Did she think she's better than him? It vexed him, infuriated him to the point he bullied her, provoked her. Especially after the quirk exam.

[F/n] not once used her quirk, instead resorted to her physical ability to get by. She scored 17 out of the 21 students in the class. Not the best but not last. It made Bakugou feel better knowing she was weak, though perplexed him. At the end of the quirk assessment, the disgruntled boy confronted her, targeting her out of the mass that was heading back to class. Midoriya wasn't around; he was sent to the nurse's office, and that terrified [f/n].

She was about to head in the direction of her friend when a figure called out. "Hey, putz!" Before she could turn around a hand grabbed her ruthlessly by the back of her collar. The sudden pull caused the girl to gag, her fingers clawing at the tight collar around her neck. Yanking [f/n] closer Bakugou snarled, "Where do you think you're going, huh?!" She could feel his breath against her neck, the hairs on her neck rising, as a shiver resonated down her spine.

[F/n]'s blood ran cold, her mouth went dry, and tears whelmed up. This couldn't be happening to her, on day one? The [h/c] haired girl knew she had to turn around sooner or later, so she did and with the intent to flee. Right when she turned around, [f/n] slapped him hard on the cheek. A sharp echo could be heard toward the entrance of UA. Tears ran down her heated face, her eyes screaming at him to leave her alone. But what she saw terrified her. Anger couldn't describe what she saw. His visage was a mixture of unforgiving, resentment, and ruthlessness. That of a predator hunting its prey.

The impact left a red mark on his shocked face but did absolutely nothing to loosen his grip on her uniform. "YOU BITCH!" [F/n] didn't have time to react. She was thrown to the ground, skidding then tumbled to a stop. When [e/c] eyes opened he was towering over her. "I was going to let you off but NOW!" [E/c] eyes widened in horror when a foot collided with her stomach. "I will make you wish you were never fucking born."

Just as he was about to grab her, a blur came into view. A figure running at full speed tackled the assailant to the ground. Two boys tussled, punching, and shouting at each other. "What the hell do you think you're doing?!" Her savior was a spiky redhead whose quirk was hardening.

The redhead—later known as Kirishima—was heading back to class when he heard a loud slapping sound and screaming. Not knowing if someone was in trouble, he sprinted back to see for himself. "GET THE FUCK OFF ME SHITTY HAIR! SHE'S THE ONE THAT HIT ME FIRST!"

[F/n] watched helplessly on the ground, saliva and tears running down her face after being kicked. 'Well this was unexpected,' she thought to herself before blacking out.
