Hey guys. This is my first ever fanfiction. I absolutely love this pairing and so I thought it'd be lovely to write about them! Please go easy on me. Also, I like constructive feedback as it helps me improve my writing and/or errors I may have overlooked while writing my story! I hope you all enjoy this! I apologise in advance for any spelling or grammatical mistakes. It's nearly midnight here and I was determined to post this today. I proof read it a few times, but who knows, I may have missed something.
Chapter 1: Rin?
Yukio had just completed his mission. Well, technically the squad hadn't completed the mission because the damned demon had gotten away. He was tired, sweaty, dirty, and a little on edge. This had to be one of the worst missions he had ever been on. The demon they were sent to eliminate escaped. The young exorcist had managed to fire a couple of bullets into its side before it fled. When the young doctor came into contact with the demon, time appeared to have stopped as the demon's pitch black eyes gazed straight into the exorcist's turquoise orbs - that is, until Yukio had a piece of mind to fire at the cursed monstrosity! Despite its seemingly large size, it managed to slip passed and make its escape unnoticed to the other members of his squad. As it was known to be able to shape-shift, this left the exorcist team running around in search of it for a good two hours before classifying the mission a failure. Yukio was on his way home when his pocket vibrated. He groaned, "What could it possibly be now." He muttered to himself, reaching for the device.
He sucked in a breath of air, and answered in his usual polite persona. "Hello? Okumura speaking."
A husky chuckle was heard on the other line, and to this Yukio internally sighed.
"Ah~ Okumura-sensei I'm glad you answered." Came the sickly sweet voice of the headmaster.
The young genius twitched. "How may I be of service, Sir Pheles?"
"I have some rather... intriguing news you may be interested in hearing..."
Yukio didn't know what he was trying to imply by placing a little too much emphasis on the "intriguing", nor did he bother questioning. It had been a long day.
"Yessir." Came his flat reply.
"Very good. Very good. Be in my office in ten minutes."
Yukio slid the device back into his front pocket, and changed his course. He was so close to home. So close to his beloved Nii-san. All he wanted right now was to curl up next to his loved one and fall asleep in the comfort of each other's presence. He sulked over the wandering thoughts of his cute nii-san in his mind as he headed towards the nearest door, pulling out the set of his special exorcist keys.
The teen made his way down the awe-inspiring halls of the true cross academy. When reaching his destination, he was greeted by large, magnificent double-doors. He hesitated for a brief moment before knocking on the grand wooden doors, and entering when cued.
"Welcome, welcome! Delighted to see that you made it, Okumura-sensei." Mephisto exclaimed from behind his enormous desk, grinning ever so widely. Yukio stood in front of the headmaster's desk, hands straight by his side with his face masked with a professional, stoic expression, awaiting expected orders.
"How was your assignment, Okumura-sensei?" The headmaster inquired in a sly and knowing tone. It was as though the elder demon already knew the answer to his own question. "The demon was much higher than a group of middle- first class exorcists could handle, sir. The suspected demon had escaped. I will have a report filed as soon as possible." Yukio robotically answered.
"Ah well, Okumura-sensei. I would not suppose you would know where the demon ended up?" Mephisto questioned, a sly smirk creeping onto his features slowly. Yukio rose a perfect brow. He knew he headmaster was toying with him, but seriously, what was with these questions. If they could track it, he wouldn't be here. "Unfortunately not, sir. Otherwise our squad would still be investigating the suspected grounds." Mesphisto chucked, as if he knew something unfortunate that happened to someo-
That's when realisation hit Yukio.
No...
Mephisto's wandering eyes searched him for any hints of emotion. "While absent from your dormitory on your mission this evening, a demon managed to infiltrate the barrier and attack Okumura-kun." He stated slowly. Yukio's eyes widened for a split second, knowing exactly where this conversation was heading. His anxiety was getting the better of him at the point in time and continued he stared wide eye'd at the headmaster, it was suddenly becoming hard to breathe.
Mephisto's eyes gleamed with mischief and he laced his fingers together. "Do not fret, Okumura-sensei. I can assure you that Okumura-kun handled the situation rather well and is in fact physically unharmed." Yukio's eyes narrowed.
Physically unharmed?
There was no way the headmaster called him all the way out here just to play with his emotions a little, then tell him that his brother is actually unharmed at all, and that he overreacted by getting worried over nothing. There had to be more to it than just that… what was the catch? "However-" Knew it. Of course there would be more. "-The demon released a strange misty substance after Okumura-kun pierced through its flesh." He paused, once again making eye contact with Yukio. "Okumura Rin's form has... changed. At this particular point in time we are unsure of how to cure his state. Our scientists have sampled some of the matter that was left over, and are testing for a cure as we speak. However we must also consider the possibility that the mist may be a diversion to hide something greater. We may need you to gather a blood sample for us as he simply would not allow anyone to come within three feet of him." As if Mephisto's grin wasn't wide enough already, it spread even wider across his face. Appearing as though it may split his face in half.
Yukio cringed. Creepy.
"For the time being, I'm afraid you will have to adapt to Okumura-kun's new features and behavior." He smirked.
"By 'new features and behavior' what exactly are you implying?" Yukio questioned, slightly worried, though not making it evident in his expression. "He has developed characteristics similar to that of a feline. A household pet to put it simply. Due to this, it is safe to assume his behavior may also resemble that of a feline." By now Yukio's face had paled, the colour drained from his features. He stared blankly at the headmaster from where he stood. Mephisto smiled. "My, what a lovely expression you have, Okumura-sensei." Yukio completely disregarded the comment. "What am I to do with Rin? How long is the testing going to take?" Yukio quickly inquired, sounding a little more desperate than he had hoped. "What an unusual reaction you have there, sensei! Unfortunately, you will have to find out for yourself." The purple haired demon shrugged slightly. "This is just as unusual to our scientists as it is to you. For now, I suppose you have to take matters into your own hands." He added in a mocking manner. Yukio knows that the scheming headmaster is up to no good.
Seeing as though he headmaster had finished for the night, Yukio decided that he'd also had enough for one night, and when dismissed, he bowed, and made his exit.
"This is going to be fun, ne?" Mephisto added almost menacingly once the teen had left.
Nii-san is an over sized cat. Yukio deadpanned.
This can't get any worse. There's no way this can get any worse.
He thought to himself, tugging at his hair as he reached the other end of the hallway, once again pulling out his exorcist keys. Images of his brother scraping the floorboards with his claws, ripping up his paperwork, and using his exorcist equipment as toys flashed through his mind. He began to sweat slightly, and his heart started to race. He pulled out the key that opened the portal to the dormitory he and his brother shared. As he inserted the key into the hole he closed his eyes, mentally preparing himself for the worse.
The door slowly creaked open. He glanced at his watch once more, it was already 2:45am on Saturday. Yukio found some relief in the fact that he would be able to get some rest before starting his work. He slowly made his way up to the second floor, his legs weighing a tonne each. As he reached the top he exhaled a deep sigh, dragging himself to his assigned room. Many thoughts playing in his mind, questioning his satanic twin's new state – this must be some kind of sick joke. He hoped he would wake up tomorrow and it will all just be a really bad dream.
He slowly reached for the door handle, turning it, and then pushing it forward. He entered the room with caution and reached for the light though failed to make contact with the switch as he was promptly tackled to the floor. The exorcist released a startled yelp as he landed on his back on the cold hard ground. "Okaeri." A familiar voice purred. "N-Nii-san!" The younger twin yelped as a shadowy figure loomed above the teen. A tail could be seen swaying side to side behind the attacker. The younger groaned, knowing he'd have to now deal with Rin so early in the morning.
"You're late." He stated bluntly.
"Indeed I am. Or am I early?" Yukio replied just as blunt
Rin growled slightly, still straddling Yukio's hips.
The teen sighed and reached over with his right hand to gently stroke the irritated teen's head, lacing his fingers in between the demon's navy blue locks to tenderly massage his scalp. He soft purr was emitted from the smaller boy's throat and this caused the taller teen's eye brows shoot up in surprise. Rin abruptly pulled away with a grumble, "Don't think you'll get away with this easily. Why're you lat-" He was cut off when the other teen began to rub the boy's scalp with more enthusiasm; tenderly trailing his fingers down to the boy's neck and back up. This seemed to cause Rin to forget his nagging, and press his face against Yukio's neck.
In his trance, Yukio brushed over something soft and furry, making it twitch. This caught his attention as he noticed his brother's newly acquired ears, and snatched his hand away from his twin's head as if it burnt him. He stared with a blank face at Rin.
What the fuck-
The boy leaned forward to lightly head-butt the other.
"What." Said Rin, clearly taking offence to his brother's actions.
"No, it's nothing." Yukio replied in haste. Rin snorted at the obvious lie.
"In any case, Nii-san. I should go clean up. Though I'm glad to see you're alright, you should probably go to sleep." Yukio started.
"Why wouldn't I be alright? I've been sitting here waiting for you all night."
"What?" Yukio blurted out.
"What" Rin replied, peering down at Yukio as though he had completely lost is marbles. "Yukio, are you okay? You should hurry up so you can sleep. I'll come with yo-"
"No, no. There isn't any need for that, nii-san. I'm filthy. Go to bed, while I go clean up." Yukio told his twin quickly, trying to create an excuse to leave the room. By now, Rin was staring at him as if he'd grown a second head. He pouted, and his ears pointed downward. Yukio chuckled at his brother's behaviour. Somehow, he found relief in seeing that Rin hadn't completely changed. He was still the Rin Yukio had always known him to be, minus the ears of course. For only a moment, Yukio was sucked into his own thoughts. He imagined his rebellious twin sprawled out on his back on the sheets, Yukio's sheets. His eyes glazed, and his legs spread as though offering himself to Yukio. He mewled as the other climbed on top of him, touching the soft milky-white skin that were his thighs, leaning down to place his lips on-
"OI. YUKIO." Rin almost yelled into his ear from above. Yukio shook his head, and upon realising that he was only daydreaming, the young exorcist mentally slapped himself for that brief but graphic thought. He attempted to remove his elder brother from on top of him and as a result, snarled at him. "Look. I'm notta kid, Yukio. I know when you're lyin' t' me. I know when you're not okay. AND YOU'RE DEFINITELY NOT OKAY." All Yukio did was sigh, and this seemed to tick the other off even more.
"What's with that anyway?" Rin questioned.
"What's what?" Yukio replied
"For a smart guy, you're really dumb"
"I certainly don't want to be hearing that from you, nii-san."
"You were lookin' at me with a real weird look. Like you were gonna eat me or somethin'" Rin said with some thought.
"Look, Nii-san…" Yukio began. He really needed to get out of here, and fast.
"Don't you "Look, Nii-san" Me. I know there's somethin' wrong." Rin growled, pinning Yukio's arms. He stared down at his younger brother with fiery eyes, only to have the other stare up at him with an apathetic expression.
"Nothing's wrong, nii-san. I assure you."
"Oh really?"
"Yes, nii-san."
"Then explain this." Rin said cockily as he ground his hips against Yukio. The poor boy gasped at the sudden contact and glared at the other, who only smirked in return.
"You think I wouldn't notice?" He asked, continuing to push his hips onto the other boy, who gasped and writhed beneath him. He smirked, knowing that Yukio wouldn't be able to get out of this one. But his fun was cut short when Yukio forcefully bucked his hips, catching the other off guard, and promptly rolling over.
"No." This time it was Yukio's turn to smirk. He held his twins wrists with one hand as he undid his tie with the other, using it as rope to bind the other.
"Are you fuckin' kidding me, Yukio." Rin mumbled as he wriggled around in his restraints.
Yukio only smiled brightly as he picked his brother up like a sack of rice, and dropped him on his bed. Slightly untying the piece of cloth around his brother's wrists, he tied his brother to the bed post instead.
"Stay." Yukio ordered. Getting up to leave, Rin kicked him right in the behind as an act of revenge.
"Don't tell me to 'stay' like I'm some kind of dumb mutt!" Rin roared after Yukio, who simply grabbed his pyjamas, and walked out the door without a worry in the world.
As Yukio walked down the hall he could faintly hear Rin screaming "baka megane" with all his fury.
