A/N: Hey all! I"m pretty pumped about this 100 themes challenge :D I got most of the themes from DeviantArt, but I changed some of them to others that I've found across the internet, and some I thought up on my own. Oh, and I will also be taking great liberties with Sentarou and Kiyone's pasts, because we don't know too much about them, and this is my fic, so I can do whatever I want :P Anyway, I've waisted enough space with this, so enjoy the first theme: Introduction.

A Bickering Love

Theme 1: Introduction

Today was a big day for Kiyone Kotetsu. She carefully ran her brush though her short blond hair for the hundredth time to make sure it was perfect. She smoothed out her clothing as she left her dorm room with an armful of notebooks just waiting to be filled with notes. She was ready to start this unforgettable day; this was her first day of class at the Spiritual Arts Academy.

Her mind was buzzing excitedly as she weaved her way through the crowd of fellow students that seemed just as jittery and eager as she was. Kiyone quickly glanced down at the slightly crumpled piece of paper that she held in her hands, which had her scheduled classes written down for her. She had already memorized when and where each of her classes were, but she was double checking just in case she misread something.

Kiyone tucked the paper away and quickly headed to the third floor. Her first class, Zanpakuto studies, was to begin shortly, and she certainly didn't want to be late on her first day. As she reached the door to the classroom, she smiled brightly and walked in. It was a large room, and it housed enough desks to seat about 50 students. A large chalkboard covered the front wall, just behind the large teacher's desk.

The eager woman quickly made her way to the front of the class. It didn't take her long, because there were only a couple other students in the room, and they were conversing off to the side of the rows of desks. She wanted the best seat in the room, which was the one that was front and center. Kiyone grinned as she stood by the desk that she had claimed as her own, but as she dropped her notebooks on it, someone else had also dropped their stuff on the desk at the same time, but from the other side. A confused and slightly irritated look crossed her face as she looked up to see who the culprit was.

Kiyone found herself staring at a young man around her age. He was about a foot taller than her, and he looked physically fit, though it was hard to tell due to his bulky uniform. His hair was short and black, and his dark brown, almost black eyes studied her closely. His thick black eyebrows were raised at Kiyone with curiosity. She stared blankly at him for a moment before moving her gaze to his stuff that was on the desk. Her desk.

"Who are you?" Kiyone asked, her eyes moving back up to his face.

"Sentarou Kotsubaki. You?"

"Kiyone Kotetsu."

They both were silent for a moment as they stared each other down. Sentarou was particularly interested in the young woman standing before him. She was short, and his larger frame easily towered over her. She had short blond hair and large gray eyes that were currently staring at him. She was probably taking in his appearance just like he was doing. He grinned and decided that he liked what he saw, but right now, she had him slightly annoyed. Her notebooks were crowding his desk, and he didn't like that.

"Well, Kiyone, as much fun as just standing here and staring at each other is, I'm afraid that you've dropped your stuff on my desk. Could you kindly move it?" Sentarou asked, with a heavy tone of arrogance to his voice.

Kiyone raised an eyebrow before narrowing her eyes. Oh no, there was no way in hell that this idiot was going to steal the best seat in the class from her.

"No way," Kiyone said angrily, "I was here first. Get lost."

"Listen, short stuff, I know it's probably hard to see from all the way down there, but I was clearly here first. Now run along." Sentarou growled, waving a hand in her direction. Their argument had caused the other students in the room to grow silent and watch the two with great interest.

Kiyone's right eye twitched with anger. This guy was really starting to piss her off. She clenched her fists as she glared daggers at Sentarou, who had a cocky grin on his face.

"Didn't you get the memo, Sentarou? The morons have to sit in the back of the class." Kiyone hissed though her teeth. A series of 'oohs' and snickers erupted from the crowd, which had grown significantly larger than when the argument had first begun. Sentarou snorted.

"You would know, you blond bimbo." Sentarou retorted, earning a gasp from the crowd as the two glared at each other. Kiyone was almost shaking from anger. She was not going to let this stupid, rude, idiotic prick have his way, especially not after he had insulted her so badly. Sentarou's thoughts were the same as he watched Kiyone's gaze shift to the chair of the desk that they were fighting over. She looked back up at him and grinned, and he immediately knew what she was up to. Kiyone quickly flung herself onto the chair, but Sentarou used his superior body mass to shove her off. She fell to the floor with a grunt and glared at Sentarou, who now sat on the chair, looking down at her with a smug grin.

"Ha, I win-Oof!" Sentarou said, but he grunted as Kiyone tackled him to the floor, pinning his arms down. He caught his breath and growled as she giggled and smiled triumphantly.

"You were saying?" Kiyone asked, laughing at the pissed off look that crossed Sentarou's face. He was not going to let her humiliate him in front of his peers, who had erupted in laughter as they watched the amusing fight.

With Kiyone distracted by her laughing, Sentarou used this opportunity to his advantage as he grabbed her shoulder and roughly pulled her to the floor. She squealed with shock as she hit the cold floor, but she recovered and, as Sentarou stood, she jumped onto his back and wrapped her legs around his abdomen. She then wrapped her arm around his neck and had him in a chokehold. This had the crowd cheering and Sentarou clawed at her arm as he gasped for breath.

"You…Bitch…" he gasped, as he was able to pry Kiyone's arm away long enough to take a breath. She was about to punch him in the head with her free arm when she was grabbed by the arm and yanked from Sentarou's back. She looked up and was horrified to be looking into the face of the teacher, which was almost purple with anger. He was a large man who was taller than Sentarou, and he was very strong, for he was able to life her and Sentarou up off the ground with ease. Without a word, he marched through the crowd of spectators, who now scrambled to find a seat, and headed for the door. He yanked it open and threw Sentarou and Kiyone to the floor, and their notebooks followed shortly after.

"Do not return to this classroom until you can act like mature adults. This is your only warning." The teacher yelled before returning to the classroom and slamming the door shut behind him. Kiyone and Sentarou glared at each other in silence for a long time before they stood up, gathered up their things, and stalked off down the hall in opposite directions without a word.

Sentarou mumbled angrily to himself as he rubbed his neck tenderly. He hated to admit it, but that woman was a force to be reckoned with, and he kind of liked that about her. But she was also stubborn and rude, and that canceled out the good. He would get her back eventually, but now Sentarou was concerned with making up a good excuse as to why his neck was messed up.

Kiyone stormed down the hallway, resisting the urge to kick the wall to vent her anger. That Sentarou was such an idiot! How dare he say such rude and arrogant things to her? She was most certainly not a blond bimbo! Well, she was blond, but the bimbo part was totally false and completely uncalled for. A large grin crossed her face as she made her way down the stairs. She had showed him though by kicking his smug ass in front of all their classmates. She may look small and harmless, but she knew how to stick up for herself. Compared to the many thugs that she had to fight off from her time in the Rukongai, Sentarou was a piece of cake. Kiyone grinned as she reached her dorm room and walked in. Her hair and clothed had been messed up in the skirmish, so she was going to fix that before her next class.

'This is going to be an interesting year.' Kiyone thought, smiling mischievously as she began thinking up some good insults for her next encounter with that idiot Sentarou.

A/N: Alright, first theme done. I could just picture them fighting over something as stupid as a seat, so I had to write about it xD But yeah, I really don't know how I feel about this chapter :/ Wow, what a good start :P Anyway, read and review, please ^^
