Kageyama's twin sister | Fumiko Kageyama | Haikyuu x OC

Lab Partners

"Kageyama Fumiko will be partnered with Tsukishima Kei."

Internally groaning, Fumiko forced the scowl off of her face and strode over to where Tsukishima was sitting, idly doodling in his book, evidently not having heard the teacher. Fumiko reached out her fingers and snapped in front of his face. "Hey. Get up, blondie; we have to head to the lab." He glared at her in response,

"It's Tsukishima-san for you- and don't tell me what to do."

Fumiko's scowl threatened to return, but she settled on a grin; much more irritating to Tsukishima, she decided. "Whatever blondie," she sang.

" I'll let you sleep through class and lose to me if that's what you really want."

Tsukishima glared up at her. He felt like slapping that smirk right off her face. "Aw, does someone not want to partner up?" she mockingly cooed as she leaned towards him. At that moment, Tsukishima was thinking of a million ways to make her regret everything she'd said to him up until this point, but his thoughts were interrupted by a cold, high pitched voice.

"Miss Kageyama, please stop causing trouble or I'm afraid I will have to report you to the principal for outright misbehaviour. Detention for half an hour after school." Fumiko slowly swivelled her head to the side, eyes widening. She hadn't realised she was being watched. The teacher surveyed her with disdain, her cold eyes glittering with displeasure.

"Y-yes...sorry, sensei." she sputtered out. Tsukishima stifled a snicker, just barely hiding his joy at seeing her get in trouble.

Fumiko watched the teacher stalk off and waited for her to round the corner until she exclaimed, "What is wrong with her? Everyone else was talking!" Looking at his expression, she snapped, "Oh, shut it, you blond beanpole. Don't tell me you've never gotten into detention before."

"Actually, I haven't," he responded, smug with his indirect victory.

What an upstanding jerk, thought Fumiko. "Oh right," she smirked. "Mr Teacher's Pet here has to suck up to the teachers, so he doesn't get a bad grade."

Before Tsukishima could respond with a scathing remark, Yamaguchi rushed into the classroom. "What are you two doing here? We're supposed to be in the lab! Hurry up; we've already started." Tsukishima adjusted his glasses as Fumiko hastily rushed past Yamaguchi to the lab. He hadn't realised the two of them had just been alone and that everyone else had left.

"Coming., he responded as he made to pick up his bag, but his arm swung at nothing. The bag was gone. That bitch, he thought.

Storming out of the classroom, he found Fumiko examining a microscope in the lab and whispered as loud as he could. "Where the hell is my bag?"

She batted her eyelashes innocently. "I don't know what you're talking about."

"Oh, once we're out of here, you're gonna get it."

"Kinky."

Tsukishima sighed exasperatedly. What was wrong with her? Why couldn't she just mind her own business? Was it her sole mission just to annoy him? He spotted the corner of his bag poking out from the stool behind her back, taunting him. He wasn't going to let her get the better of him. Taking a deep breath, Tsukishima reached his arm around her torso. The bag was right there; he could nearly reach it- "Woah woah, I was just joking; no funny business, blondie." Fumiko had grabbed his wrist, and he turned his head to see her face mere inches from his, her smile fading.

She patted her skirt pocket with her free hand- "I have a pair of brass knuckles in here, and I'm not afraid to use them, so don't try anything." A moment later, she frowned, and her voice turned cold. "Although, I have to say I'm disappointed. As annoying as you are, I didn't think you were that kind of guy, Tsukishima."

Tsukishima blinked. It took him a moment to process the situation. When he realised what she was thinking, he wrenched his hand out of her iron grip, stumbling backwards. He focused on maintaining a calm tone as he massaged his wrist gingerly. "You got the wrong idea, idiot. My bag; it's behind you."

Now it was Fumiko's turn to blink. She turned around, confused, and picked up the bag. She stared at it for a moment and burst out laughing. Her cheeks tinged with pink, and she clutched her stomach as her laugh rang out in the room. Other students looked at them curiously, some entranced by her blue eyes, lit up with mirth. Tsukishima felt the tell-tale heat rise to his cheeks and hastened to cover his embarrassment. "Oh man," Fumiko wiped her eyes, "I totally got the wrong idea. Sorry, blondie."

"Well yeah, I'm not a pervert," he said. " And stop calling me blondie," he added, as he took the bag from her and slung it over his shoulder. Now that the ordeal was over, they both noticed the uncomfortable feeling of someone's gaze burning into the back of their heads. Slowly turning around, their eyes made contact with the teacher's piercing glare.

"THAT'S IT!" she yelled, her fury radiating in waves. "DETENTION FOR BOTH OF YOU, AN HOUR EVERY DAY FOR THE REST OF THIS WEEK!". Her voice sounded like the whistle of a kettle going off, high-pitched and squeaky. After her outburst, she cast a meaningful glance towards Yamaguchi. "And you, I expect you to make sure these two behave." and with that, she promptly flounced out of the room, scribbling notes furiously onto a piece of paper.

Tsukishima looked daggers at Fumiko, his brief spell of good humour from before disappearing. "Great. Congratulations, you dragged me down with you, you-"

"Don't worry, Tsukki, we can sort this out." Yamaguchi interrupted before Tsukishima could finish his sentence. If there was anyone Fumiko felt bad for, it was Yamaguchi. He didn't deserve to be shoved into the middle of their chaos to play the role of the mediator.

"I'm sorry, Yamaguchi. I didn't mean for this to happen."

"It's okay, Kageyama-san." He smiled. "I'm sure we can get her to let you guys off after a couple of days of detention, at least." his smile faltered. "Daichi-san won't be too happy, though." He and Tsukishima headed back to class, and Fumiko was left standing in the lab. She mused as to who this Daichi-san could be. A teacher? Friend? Relative? Whatever it was, she was still dismayed that she would have to skip martial arts club for the rest of the week.

Fumiko had only picked up martial arts the year before attending Karasuno, but she had advanced quickly. The swift, power-packed blows she would deliver made her feel strong, confident, and most importantly: in control. Something she hadn't been feeling until just a little while ago. Even thinking about her time at Kitagawa Daiichi made Fumiko feel pathetic, weak and small. She had been humiliated by her closest friends and had since sworn to never draw near them again. Even now, well-versed in the martial arts as she is, she still hasn't found the courage to face them. Their jeering, leering voices were still fresh in her head. Fumiko shook herself. Get a grip, she thought to herself. She took in a long, shaky breath in an attempt to steady her racing pulse.

"Hey, you okay there miss?" a mop of unruly orange hair peeked from behind her shoulder.
