Those who can, do. Those who can't, teach. (OC/Reader x Aizawa)

Student vs Teacher Battles?

Friday had come, and with the help of Aizawa, Y/N was finally prepared for the Student vs Teacher exams. The students of 1-A stood outside as she explained the rules. Aizawa noticed the way she favoured her left leg, and every so often itched her right. What had he seen a few nights ago...?

"Robots won't challenge you enough, so you guys are going to be fighting us! But to make it fair, we'll be wearing training weights equal to half our body weight." Y/N wore a devilish grin, as the students groaned. She explained the rules, that they needed to either escape or handcuff their teachers to pass.

"These fights have been determined using your weaknesses, and relationships with your peers. So, in no particular order, Midoriya and Bakugo vs All Might." She continued to read off the names.

"And finally, Jiro and Shoji vs myself." She smirked. Jiro's hearing would need to be impeccable to hear Y/N approaching, and Shoji's ability to create extra eyes and ears won't be very good against someone who spent their career making themselves as quiet and small as possible for stealth missions.

The students began to talk amongst themselves, as she approached the two meant to fight her.

"Shoji. Jiro." She got their attention. They seemed confident they'd be able to hear her coming, but little did they know...

"I know that it's not fair that you don't know what my quirk is. So, just for you two, I'm going to tell you. And that will also explain why you're against me. You've already seen my capture weapons, so I'll spare you the explanation of that." Their expressions changed.

"I can hold my breath for an extended period of time, between 9-12 minutes. This also reduces my heart rate to 1bpm for that amount of time, making it virtually impossible to hear me coming. My hero costume is also designed to make no noise, as you might have noticed. During my hero career, I mainly did stealth missions. This is why you're matched with me, with your quirk giving you exceptional hearing, Jiro, and your ability to make extra eyes and ears to scope out an area, Shoji. Good luck." She left the pair, who were trying to push aside their shock to come up with a plan. They had an hour to come up with them before their fight commenced.

"Jiro and Shoji, Practical Exam. Ready, go." The loudspeaker sounded out.

The exam took place in a dark office building, with the exit just outside. Y/N took a deep breath, holding it. Slowly, she walked through the entrance of the building, crouching down. It was extremely dark, but she still needed to stay under cover.

On the top floor, was Jiro and Shoji.

"Can you hear anything? Footsteps, anything?" Shoji asked, his arms with ears on the end pressed to the floor. Jiro's earphone jack was in the floor as well.

"No, nothing. You?" Shoji shook his head.

"Normally I'd be able to hear a heartbeat, or even breathing, but..."

"We'll just have to trick her."

Y/N remained quiet, heading up the stairwell, taking very careful steps. It had been five minutes at this point, but she pressed on, heading up the building. She crouched through the third floor, until catching something on her foot. Looking down, she had set off a tripwire that she couldn't see in the dark. The wire lead to a piece of paper with a stapler on top. The paper fell off, the stapler hitting the floor with a 'clack'.

Shit.

Y/N ducked behind a desk, feeling the slight ache of the training weights now. She tried to make her way to the stairwell entrance, hiding behind a wall, waiting for them to come down. But the time was passing, and she was beginning to run out of breath. Unable to keep it any longer, she quietly resumed breathing.
