Mitsuko Souma was going to be the death of him.

Every day, she showed up late to class, picked on other students, and maintained higher than acceptable speeds in the halls. Every time he reprimanded her, she'd just give him this look, like she was just playing with him. Like she didn't take him seriously, like, sure, she'd go to detention… ten minutes late and complain loudly throughout the entire thing, no matter how many times she was shushed.

And, frankly, Kiyotaka Ishimaru was sick of it.

So, when he ran into her and one of his male classmates kissing rather furiously in an unused classroom, he sent the male away with a detention slip and stood in front of Mitsuko, who was sitting on a desk, one leg dangling down and the other up on the desk next to her.

He felt his face heat up and focused on her eyes. "Souma-kun!" he said. "You are a constant disturbance to our school!"

She tilted her head to the side and pouted in a plea of false innocence. "Really? Are you going to discipline me, hall monitor?"

Calm down Ishimaru, next year you'll be in Hope's Peak and you won't have to deal with this anymore. He took a deep breath and set his face in a scowl.

"I have put you in detention numerous times and it has not gotten through to you! What do I need to do to make you see that you need to behave?" he said.

"Watch out, hall monitor," she said. "You're getting a little loud. Wouldn't want to break any rules, would we?"

"I don't break rules," he said. "You, however, have broken every single rule this school has at least once. The school has even had to make new rules because of your blatant disregard of anything appropriate!"

"Hm?" she said. "Really? Why don't you describe some of that for me?"

With that, she leaned back, propping her hands on a desk pushed close to the one she was sitting on and spreading her legs a bit wider. Ishimaru's scowl deepened and he clenched his hands into fists, fingernails biting into his skin. He looked away, staring at the wall. She laughed and the sound of a desk scraping screeched through the room, followed by a small yelp and a thud.

Ishimaru glanced back and she was on a pile on the floor, propped up on one elbow. The fact that she was an incorrigible she-devil poking at the back of his mind, he rushed to her aid, kneeling on one knee next to her.

"Are you alright?" he asked. She smirked.

"So concerned for your fellow student," she said, her hand coming up and trailing over the front of his uniform. He froze. "I hate you so much, you know that? You think you're so much better than all of us."

He swallowed. "I… I got where I am through hard work and…"

Her fingers moved from his chest to his face, cupping his cheek, brushing his lip with her thumb on the way. He was acutely aware of everything, of his heart pounding and his face heating up and of her face, getting closer and closer to his and this was wrong.

With a strangled yelp, he backed up, pushing himself backward with his hands until his back hit a wall. She laughed again and stood up, giving him a little wave as she left.

It took him a while to catch his breath, the thought of not being in this school the next year the only thing able to keep him sane.

I'm… not quite sure what this is? Kind of a, 'what if Mitsuko went to Ishimaru's middle school' type of thing? Something like that. Either way, I'm not totally sure on Mitsuko – I've only seen the movie of Battle Royale, and it's been a few months, so I seriously relied on Ishimaru to carry me through this, but other than that…

Oh, and this was requested by an anon on Tumblr, who wanted Mitsuko and Ishimaru and a hatelove type of thing. This is a little short, but… I don't know, I'm kind of fond of it!
