Well what can I say, this is really really late. And I don't hate it but it's definitely not my favorite. I was pretty distracted when I wrote this chapter. So sorry if it sucks. The couple will definitely be 2718 but I'll add Mukuro in there to pretty much give Hibari a hard time. But don't worry too much 1827 fans! There's gonna be a little somethin at the end of the story for you kinda.

Pairings: Tsuna x Kyouya, Takeshi x Hayato.

"-Tsuna…Dame-Tsuna wake up."

Tsuna's eyes shot open when a sharp pain shot through his skull.

"Kicking him is not going to help Reborn." There was a loud smack and Tsuna heard someone fall over with a loud thump. " Ow! Stop doing that!"

"I'll bite you to death."

Tsuna carefully sat up while he rubbed the sore spot on his head. "Th-that hurt R-Reborn…" He muttered, staring down into his lap. He groggily closed his eyes for a moment, trying to recall what happened. He remembered Hibari waking him up by bursting into his window, then he showed Hibari where Shamal lived, then Reborn showed up and asked what Shamal had done to Hibari, he had said Shamal turned him into a girl. Tsuna's cheeks flushed brightly at that part but he tried to ignore it. After that he had laughed at something Hibari said then…oh.

His eyes opened widely and his head jerked up to look around him. His large brown eyes landed on his Cloud Guardian who was scowling at him with his arms crossed. Tsuna ignored the scowl as his eyes slowly traveled up to the top of the raven haired teen's head. However he didn't find what he was searching for since Hibari had placed his hood back on.

"Dame-Tsuna if you faint again I'll shoot you."

Tsuna blinked and looked over to where the infant hitman was standing. "Faint…?"

Reborn scowled at him, "You fainted idiot."

Oh yeah.

Tsuna rubbed his head and looked down at his lap. "Oh…sorry…"

He jumped when he felt something whiz by his face followed by a thump. He looked up and in the direction of the noise and he jerked back when he saw a tonfa lodged in the wall right next to his head. "Hiiiiee!" He yelled, scrambling to try and get off the couch but failing. He ended up flopping onto the floor.

"Oi don't destroy my apartment!"

"Call me a girl once more herbivore, and I'll bite you to death." Hibari hissed and Tsuna could have sworn he saw a light pink dusting the prefect's pale cheeks. Hibari caught his gaze and quickly turned his head away. He crossed his arms and kicked Shamal, who was lying on the ground, face contorted in pain.

"S-sorry Hibari-san…" Tsuna apologized somewhat quietly while he looked down at his lap and bit his bottom lip.

"Hibari, take your hood off." Reborn ordered suddenly.

Hibari's head whipped around so fast that Tsuna started to worry that he might get some kind of whiplash. "What?"

Reborn sighed and sat down, staring at the black haired teen unflinchingly. "Just take them out. It's not very comfortable stuffing them away is it?"

The head of the Disciplinary Committee frowned and his glare lessened considerably. Tsuna looked up and his already large brown eyes grew even larger when he saw Hibari furrowing his eyebrows and biting his lip. Dare he say that with those now large eyes and feminine face, Hibari looked cute.

"Just do it, we all know." Reborn ordered with a hint of impatience.

Hibari's eyes flickered up to look at the infant for a brief moment before he looked back down at his feet and slowly reached up to remove his hood.

Tsuna's heart started to thump rapidly as he actually leaned forward and stared intently at Hibari's head. Long, pale fingers carefully yanked the hood off and two furry, black cat ears popped up alert. Tsuna breathed in quietly and one of the ears twitched and flicked his way before Hibari glared at him.

"Tail too."

The older teen looked over at the small hitman before he hesitantly reached behind him to free his new feline tail.

Tsuna honestly couldn't help but stare at him.

Hibari shifted uncomfortably under all their scrutiny. His lengthy black tail wrapped around his hips self-consciously and his fluffy second pair of ears flipped to lie on either side of his face. "Stop staring at me." He snapped, staring down at the floor. For some strange reason he was feeling self-conscious, which was weir because he was Hibari Kyouya; simple as that. He glared, which was harder than it seemed with larger more round eyes, at the perverted doctor. "Get rid of them."

Reborn shifted his gaze to Shamal. "Shamal, give him the antidote."

The black haired male leaned up, not getting off the floor, and scooting as far away from the grumpy feline male as he could. He avoided eye contact with everyone and scratched his head. "It's not really a disease like last time." He informed evasively.

Reborn crossed his arms. "Whatever it is, cure him."

Tsuna blinked and frowned, "Don't tell me-"

Shamal glared at the Decimo, trying to shut him up. Thankfully it worked but Hibari and Reborn were both staring at him now. "Well you see…there isn't really, possibly, maybe a way to fix it…"

Hibari was immediately by his side, ready to beat him to a pulp.

"Wait!" The doctor cried, throwing his hands in front of him.

"You have no way to cure him?" Tsuna asked unbelievingly. The damned doctor created some cat disease and had absolutely no cure for it? Really he shouldn't be so surprised; he didn't have a cure for the Gokudera experiment. Thank god he was able to make a cure for that Sakura disease he had given Hibari before.

Hibari leaned in further over the older male, a murderous aura surrounding him.

"I-not right now I don't, BUT!" He yelled, noticing Hibari's tonfas appear in his hands. "I can make one, just give me some time!"

"Wait Hibari." Reborn ordered. Hibari paused and looked back at him a little confused as to why the infant would stop him. "How much time?" Reborn asked Shamal.

"H-huh?"

"How much time until you can make an antidote?" Reborn repeated, only letting in a trace of annoyance leak into his voice.

"I told you it wasn't a disease…"

Hibari's eyes narrowed further (if that was even possible) and got ready to beat his skull in with a tonfa. Reborn nor Tsuna looked like they were about to stop him so Shamal started to panic. Though he wondered why, Hibari was a freaking moody teenager not a grown man, Shamal should easily be able to take him down. And now that he had those extra appendages, it should make it even easier since they were actually pretty sensitive when tugged or damaged. He frowned and shook his head to get rid of the thought as soon as it had come. Hibari wouldn't take too kindly to getting an ass kicking, even though he definitely needed one (in his opinion).

"Two months, three tops."

Reborn was silent for a few moments before he nodded. "Hibari."

Said male looked over at him.

"He will work on a cure."

Hibari glared and straightened. "I am not having these things for that long." He hissed coldly. Tsuna couldn't help but think he looked like a riled up cat, his two appendages atop his head were now laying flat against his skull and his tail was even puffed up. The brown haired boy tried to hold back a laugh and was thankful that Hibari didn't seem to notice his struggle.

Reborn lifted his fedora hat a bit to expose his eyes more clearly. He looked back down at Shamal. "Two months or I will kill you myself."

Shamal gulped and slowly nodded his head. No way was he even going to try and go against Reborn.

Hibari opened his mouth, ready to voice his protest but Reborn held up a hand. "You cannot do it in one?" He asked the doctor.

Shamal snorted and crossed his arms. "No, I can't. I have a job you know."

Hibari kicked him. "I don't care."

"If I get fired I won't be able to afford making a cure."

Reborn halted Hibari once again. "He's right Hibari. Plus if you bite him to death he won't be alive to even fix his stupid experiment."

Shamal frowned at the insult before turning to look up at Hibari and nodding enthusiastically.

"I will let you beat him up afterwards." Reborn informed casually. Tsuna mentally sighed as he pulled himself back up on the couch.

Hibari stared down at Shamal for a moment before scoffing and moving away from him, tonfas disappearing. He walked until he decided he was far enough away from everyone in the room and crossed his arms, tail swaying lazily behind him.

Tsuna eyed his tail but quickly looked away when Hibari caught him staring.

"Alright Shamal, tell Hibari about those things."

Shamal stood and his face brightened. "Ooo, I made a manual, hold on!"

Tsuna raised an eyebrow. 'A manual? For cat ears and a tail?' He looked at Reborn who only shrugged.

Shamal came back into the room, holding a small thin book. He showed the cover to them.

"'Your cat accessories and you. A guide to your new appendages.'" Tsuna read aloud. "Hiiiiee! What's up with that?"

Shamal threw the small book at Hibari who easily caught it. The raven haired teen glared at him for a moment before turning the manual over to look at the cover. It was a simple white cover with black, messy handwriting and horrible little drawings of cat ears and tails all over. Hibari snorted before opening to look at the first page which was an index. Hibari scanned the list (it wasn't very long) and turned to the section that had information on how to take care of his new 'accessories.' It took him much longer than it usually would have to read it since he was trying to read the writing. It was like trying to decode some complicated code or trying to read a whole new language.

'Taking care of your new ears and tail shouldn't be too hard, though if you have acquired the cat's hatred for water, it will be harder than taking a simple shower. The cat licks itself to keep its fur clean, but you cannot do that because you cannot reach your ears or tail with your tongue. Unless of course you want some other human to do it, it would be impossible to clean them with a tongue. Cat's mouths are no cleaner than a human's so it would just be better to wash them without getting your entire body wet. Just use the necessary amount of water and soap and wash until you feel they are clean enough. Of course if you haven't acquired a hatred for water, washing them in the shower should be no problem. Keep washing and they should stay super soft and shiny!'

Hibari scowled down at it before flipping back to the index.

"Alright can you all leave now? I have work to do."

Hibari closed the manual and looked up at the doctor. "What does this mean?" He asked coldly, holding up the manual and pointing to a section. "Sensitive?"

Shamal crossed his arms and looked at him disdain. "Sensitive has a lot of meanings. In this case it means-"

"I know what sensitive means herbivore." Hibari hissed.

"Just explain Shamal." Reborn ordered, somewhat annoyed. Stupid doctor just couldn't be simple, he just had to keep pissing the Cloud Guardian off.

Shamal sighed. "If you tried to pull them off it would be extremely painful, like yanking off your arm or something. If you tired to cut them off, well just think of cutting off…" his eyes flickered down south and he nodded his head slightly, "you know what." He winced, just thinking about it made him want to cover his crotch protectively.

Both Tsuna's and Hibari's eyes widened. Reborn's face stayed the same as usual but he mentally flinched. He might be a baby now, but he was a man once.

Before Shamal knew what had happened, he was suddenly crumpled on the floor, pain blooming in his shoulder. He blinked before hissing in pain and clutching his shoulder. He looked up to see Hibari standing above him, eyebrows furrowed slightly, ears pressed back, and tail wrapped around his middle.

"Why would you even make something like these?" He hissed.

"He's a pervert." Reborn informed simply as he stood up. Tsuna glanced at him and also stood, letting the small infant jump on his shoulder. "Hibari, what are you going to do about school?"

Hibari glared at Shamal once more before he backed away, hiding his tonfas once more. He turned to look at Reborn and Tsuna. "What do you mean?"

Tsuna raised an eyebrow and looked over at Reborn. "Hibari-san doesn't go to class."

"He still shows up at school idiot." Reborn snapped before looking back at Hibari. "So? Are you going to try and hide them?"

Hibari was silent for a moment before he snorted. "No one will say anything." He replied confidently. Tsuna sweat dropped but started to follow the older teen when he walked toward the broken door. Shamal shot to his feet, glaring at all of them.

"Oi what about my door?" He shouted after them.

Tsuna turned his head to glance at him before continuing on his way. Reborn smirked and pulled his hat down over his eyes. "Think of it as a gift from Hibari."

"What- Oi!"

.

.

.

The three of them walked in silence for a bit before Hibari suddenly stopped and whipped around to face them. Tsuna blinked and quickly put on the brakes before he bumped into him.

"Herbivore."

"Y-yes Hibari-san?"

Hibari stared at him for a moment and Tsuna started to notice that his eye color seemed more pronounced. Another effect of the neko-disease?

Hibari's eyes narrowed but it was hardly noticeable. "Stop staring." He snapped.

Tsuna blinked and looked around them. He definitely wasn't the only one staring so why was he getting yelled at? "Um, ok. Sorry." He apologized identifying the uncomfortable look on Hibari's face. "Maybe you should put your hood back on and hide your tail if you're uncomfortable…" He mumbled quietly.

Hibari seemed surprised. "…I'm not uncomfortable, herbivore." He informed crossing his arms and looking to the side. Reborn smirked and jumped off of Tsuna's shoulder, disappearing into the crowd of people. Neither of the teens seemed to notice however.

Tsuna smiled, "Ok." He said simply before starting to walk away, smile still in place.

Hibari blinked and looked up disbelievingly. The herbivore was actually walking away from him? He frowned and hurried after the brunette, trying to ignore the stares following him. "Herbivore." He hissed, glancing around as if he was afraid to be spotted with Tsuna. When the damned herbivore didn't stop he glared at his back and rushed forward to grab the hood of his jacket, effectively pulling him to a stop.

Tsuna made a slight choking noise before he turned his head to look at Hibari. "Hibari-san are you trying to choke me?" He yelped when Hibari yanked harder. He quickly reached up and grabbed Hibari's hand that was clutching onto his hood, trying to pry his fingers off. Now he really regretted wearing a jacket, it was hot and Hibari was using it as a weapon.

He paused when he caught the look on Hibari's face. He resembled a neglected kitty. Tsuna mentally sighed and he wanted to kick himself. It wasn't like he intentionally ignored Hibari…well he did but he really didn't think that it would affect him this much. He expected Hibari to get angry and 'bite him to death'. "S-sorry Hibari-san…" He murmured, giving up on freeing his hood from Hibari's strong grip. Now his hand rested on Hibari's pale one and his face was apologetic.

Hibari blinked before quickly releasing Tsuna's hood and yanking his hand away. He stepped back away from the brunette, suddenly not liking their close proximity. He glared and crossed his arms, "Why are you apologizing?" He asked coolly.

Tsuna raised an eyebrow. "Because I ignored you and hurt your feelings?"

The black haired male flushed slightly, quickly trying to fight it. Why on earth was this herbivore reading him so well today? He didn't like it in the least. In fact, why was he even feeling so many emotions? It had to be this damn cat disease. Once it was gone he was definitely going to bite that pervert herbivore to death. This whole thing was majorly damaging his reputation and pride already. He glared at Tsuna. "Stop treating me like a girl." He snapped.

Tsuna looked completely confused. "I'm not-"

"Yes you are herbivore."

The brunette furrowed his eyebrows as he stared at his Cloud Guardian. Why was he being so emotional? PMS? No that was for women… but Hibari had all of the emotional symptoms…

He frowned in realization.

'Oh god I am treating Hibari-san like a woman.'

"I am so sorry Hibari-san." He apologized sincerely.

"S-stop apologizing." Hibari hissed, blushing. He actually stuttered? What the hell was wrong with him? He rubbed his palm against one of his eyes, his tail once again wrapping around his waist. A thing he started to notice he did whenever he felt self-conscious. It was almost like wrapping his hands around himself in an effort to hide from other's prying eyes.

Tsuna watched him quietly, not quite believing that he stuttered and was currently blushing, of all things. "Ok I'll stop Hibari-san." He informed somewhat awkwardly.

Hibari only glanced at him before turning away and gently pulling his hood over his head. His black tail snaked under his jacket and shirt to hide. "I will send someone over to fix your window." He informed emotionlessly.

Tsuna frowned and nodded before realizing that Hibari couldn't see him. "Ah ok."

Hibari turned his head to look at him and opened his mouth to say something, giving Tsuna a good view of his new sharpened incisors. However two familiar voices interrupted him.

"Juudaime!"

"Tsuna! Hibari!"

Tsuna looked over to see his two best friends walking toward them. Gokudera looked at Hibari with disdain before he turned to look at Tsuna, now all smiles and sunshine. Yamamoto had his usual smile in place and his two hands behind his head in a casual pose. How they both recognized Hibari when he had his hood on and no school uniform was a mystery to Tsuna.

Hibari quickly turned back and started to walk away. "I'm leaving." He informed Tsuna.

"Hibari! Why you leavin so soon?" Yamamoto asked, suddenly right next to the prefect. He raised his hand and Tsuna realized what he was about to do. He could only watch in horror as his hand clapped Hibari's back, therefore crushing his apparently sensitive tail.

Hibari stiffened in hissed in pain. He arched in an effort to escape Yamamoto's hand and stumbled forward slightly. Yamamoto removed his hand from his back and looked at it in confusion before looking back at Hibari who was standing completely still.

Hibari clenched his eyes shut, trying not to let his pain known to the other herbivores. He knew it was already too late however.

"Hibari?" Yamamoto questioned.

Gokudera glared at Yamamoto. "Baseball idiot I told you, you can't keep hitting people on the back like that!"

Tsuna watched Hibari carefully. "Ah, let's go guys. Hibari-san doesn't like-Hiiiiee! Yamamoto!"

Yamamoto had been silent the whole time, eyes going back and forth between his hand and Hibari's back. When Tsuna started talking, he suddenly reached for Hibari's jacket, grabbing it and his shirt and yanking it up, exposing his pale back and a curled up furry black tail that suspiciously resembled a feline tail. His eyes grew larger along with Tsuna's and Gokudera's.

Hibari quickly whirled around, but since Yamamoto hadn't release his clothes, his jacket and shirt were twisted awkwardly around him and rose up to expose his flat stomach. Once again his tail wrapped around his waist, signaling Tsuna that he was feeling self-conscious. 'Well Hibari-san has no reason to feel that way, he has a nice bod-Hiiiiee!'

"What the hell is…that?" Gokudera asked walking closer to Hibari and leaning forward to inspect the lengthy black tail. He reached out and grabbed it, running his fingers over it before he was struck with a sudden idea. Not releasing Hibari's tail, he reached up and pulled the prefect's hood down, revealing two feline ears. With his free hand he started to touch the ear experimentally.

Hibari shuddered when Gokudera started unintentionally stroking his tail and gently rubbing his ear. Yamamoto blinked and reached up to poke his other ear. Their combined touching to his sensitive appendages sent unwanted zings of pleasure straight to his gut and down…down there.

Tsuna blinked when he started to notice that Hibari wasn't actually in pain. His face was slightly flushing and he wiggled in an effort to escape their touches.

"St-stop-nn…"

Tsuna immediately flushed, finally realizing what Hibari was feeling. Well Shamal did say that they were sensitive…apparently he forgot to mention that they could bring pleasure, not only pain. He looked at Hibari's flushed face to find the raven haired teen looking directly at him, a pleading look on his face.

'Th-they're molesting Hibari-san!'

"Ts-Tsunayoshi…"

Tsuna immediately flushed a darker shade of red, feeling something shoot through his body. Hibari had just said…no moaned his name.

Gokudera and Yamamoto blinked, backing up and releasing Hibari who almost crumbled onto his knees. Tsuna was quickly by his side, practically dragging him away from the two other guardians. "S-sorry Gokudera-kun, Yamamoto!" He yelled behind him to the two confused males.

"Eh?" Yamamoto asked, confused.

"Juudaime!"

Hibari was actually panting and Tsuna tried to fight away the image of the aroused usually aloof Cloud. His face flushed and he was jerked to a stop when Hibari grabbed his jacket and stopped. He looked back at him questioningly, trying to ignore the flush on both his and Hibari's face.

"I-I can walk by myself." Hibari snapped, breathing heavily.

"Ah, sorry…"

"Juudaime!"

Tsuna's eyes widened and he quickly grabbed Hibari's hand before making a run for it. Hibari stumbled after him, not expecting to be pulled along. Thankfully his head was clearing and the fire that was previously shooting through his body was quickly disappearing which meant that his…problem was also disappearing.

Tsuna didn't stop running even when Gokudera's shouting couldn't be heard. He ran and ran, dragging the Neko-Hibari behind him.

A/N: So maybe I'm layin it on too thick that Hibari's gonna be the uke I guess, but the kitty disease is making him into one. Oh well hopefully you liked it.

I didn't look for errors in this one so sorry if there are any, I was in a bit of a hurry.

Also I did some research about how clean a cat's mouth was and apparently they're about as clean as ours. I thought they'd be cleaner but they eat like rodents and stuff so it makes sense. I could be wrong though, they didn't really give me a clear answer.

Heh heh, poor Hibari got unintentionally molested by Gokudera and Yamamoto, poor boy.

Anway, didja like the manual?
