Note :
- Tsuna has a twin. Byakuran has a twin too. ( so 2 OCs? I don't really consider them as OC. I see them more as an alternate Tsuna and Byakuran but with different names )

Title : Please Don't Let Reborn Know I Have A Brother
Chapter 1 : Headache Calls For A Phone Call

Sawada Ienari, supposedly only heir to the throne of history's bloodiest mafia famiglia, supposedly the civilian middle school brat who defeated the boss of an infamous team of top rate assassins, supposedly the hero who travelled to the future and saved the fucking world from a crazed marshmallow-obsessed dick, the direct descendant of Vongola Primo with the purest flame sky flame in the past hundred years and hyper intuition stronger than anyone else in the world, that same person cried quite pathetically in the middle of math class.

Sometimes his hyper intuition proved to be too powerful.

"Stupid intuition… Why can't you be a little gentle when there's a threat around…? A fluffy warm buzz in the chest maybe? But nope. You just had to be an asshole and give me a full blown headache…" grumbled the brunet to himself. Said brunet made more alien noises as he slammed his face on his desk.

Why? Why must his intuition flagged another threat dooming his life? They just got back from the future two days ago dammit!

Ever so helpful Hayato stood by his boss' side with an expression of clear worry. "A-Are you okay, Jyuudaime? Do you need me to carry you to the infirmary?"

"Yeah, Ienari. You look a bit pale." Yamamoto helpfully added.

The new math teacher was an angel, much better than Nezu-sensei. She tolerated her students' rowdiness and tried to understand their situations ( even though she still hadn't figured out which screws were lost from their brains ).

Angelic math teacher lowered the textbook in hand, lips curving into a tiny frown. "Do you need to be excused, Sawada? You don't look or sound too good."

"M' fine, sensei." said Ienari while waving his arm to show just how fine he was.

Which wasn't really convincing considering how that arm flailed like noodles before falling limp with an ugly thud.

'Stupid, stupid intuition…'

The last thing Ienari heard was his name being called by both Takeshi and Hayato. Everything after that was a painful blur.

Stupid, stupid intuition.

.

Ienari hated his intuition. He had it ever since he could remember. Whenever something bad was about to happen, he felt it.

What he felt wasn't just a psychic buzz as portrayed in movies or cartoons. It felt like swallowing a kitchen knife and forced to run a marathon, said knife stuck in his throat. That was only the best of it.

He still remembered the week when Reborn first arrived, or the day when he first met Basil and the Varia, or hours before he was hit with the bazooka and was sent to the future. Shit felt like a thousand razors skinning him alive, inside and out.

The only good thing he liked about his intuition was when his body automatically jerked to the side milliseconds before an attack hit him, specifically Reborn's kicks and bullets.

But other than that, nope. He wished he never had it in the first place.

He usually tolerated the pain of a foreboding. But that day, it was unbearable.

Even decapitation was preferred over the unnatural waves of pain he had to go through.

While that kind of warning rarely happened, usually when the so-called threat will break him both physically and mentally, he knew of only one way to end it all.

And god, he wished he didn't need to do it at all.

.

"Reborn-san… Is Jyuudaime going to be okay…?"

"He'll be fine. You know how intuition works."

"But…"

To be honest, Reborn wasn't sure whether the Vongola heir would be fine or not. Sure, Ienari had very bad headaches or chest pains in the past, but this. This was different.

Ienari passed out on the school infirmary bed. The brunet tossed side to side as if trying to fight the pain, pitifully gasping for air.

Shamal ( after receiving a series of threats ) ran a thorough diagnosis on Ienari, but nothing came out as anything abnormal. Ienari had a huge migraine, and that was it. Nothing else seemed to be affecting his health.

"He passed out from the pain, that's all I can say." Shamal slapped Ienari's health file to his ex-student. With nothing else to do and no women around to flirt with, the doctor left.

Hayato was close to tears. He never wanted to see his boss hurt ever again, not after what happened in the future. To see his boss in such a devastating state…

"What shall we do now, Reborn-san…? Jyuudaime never collapsed before… I-I… What should we do…?"

Reborn stayed quiet. Without the supposed-to-be boss around, it was up to him to hold the guardians together.

He needed to do something before his student dies for real.

The hitman knew when death is coming, and death was currently knocking on Ienari's doors. He felt life leaking out of the brunet's body. If given time, Ienari's body might break from the strain.

An hour after Ienari first collapsed, Reborn called Nono and Iemitsu concerning the state Ienari was in. Iemitsu of course provided no useful information to help his own son, claiming that it was the first time Ienari had passed out from his hyper intuition. Nono on the other hand had never heard of such cases. Not even Primo had that much trouble from his hyper intuition.

Sending Ienari to Italy would take too much time.

Symptoms didn't add up to anything.

Even the best doctor in the underworld couldn't do anything about Ienari's condition.

They were running out of option.

"Hayato. Find the strongest painkiller they have here, then give it to Ienari." Reborn whispered out the order. He barely kept himself composed. He couldn't afford to lose another sky, not after Luce's death.

"Yes, Reborn-san! Right away!"

With a quick bow, Hayato left to the infirmary's medicine cabinet to find anything to relieve of his boss' pain. He trusted Reborn to keep an eye on Ienari in case something happened.

Reborn was left alone with Ienari, a large sheet of white separated them from the world.

Nobody could see them. Things would still be okay if Reborn drop his mask for a few minutes, just until the Vongola medics team arrive.

"You better not die, Dame-Ie…"

Reborn had tutored Sawada Ienari for almost 2 years. Honestly, he wasn't expecting Ienari's intuition to react negatively to… everything. Whenever his intuition acted up, Reborn held his breath in, hoping that his official charge won't suddenly die.

Nothing short of a miracle happened when Ienari cracked his eyes open, and of course accompanied by panting and bodily spasms.

"Re…born…? Am I really awake…?"

Ienari couldn't tell if he was still trapped in sleep or finally getting back a sense of reality, not with all the weird dark spots dancing in his line of vision. By the feel of it, he only had a few short minutes before passing out again.

He needed to do it. He needed to do it now.

Reborn, being Ienari's ever-so-caring tutor immediately jumped to his student's side, hand instinctively reached out to hold Leon. What would he do then? Shoot him? Call the entire Vongola to tell them of the good news?

He didn't know.

"Re…born… You have to…"

The suffering Ienari couldn't finish the sentence when another wave of nausea hit him in full force. He almost threw up on the bed.

Reborn hated it; seeing his charge dying without reason while nothing else can be done to change it. When the fuck will Vongola's medics team arrive?

"Ienari, tell me what's wrong…"

"Out…"

"Ie-"

"I said OUT…!"

Taken aback by Ienari's defiance, Reborn took a step back. That was the first time Ienari raised his voice towards him. It was almost… scary. All of a sudden, the teen in front of him seemed distant; a stranger.

His heart told him to quietly leave, but instinct screamed at him to stay.

"Please… I w-won't ask for anything more…"

Fuck. Who was Reborn kidding? Hell if he turned down one of Ienari's very rare sincere request. With a cracking voice like that trembling out of the brunet's lips, Reborn would kill a man to stop that mouth from sounding so fragile.

He truly had gone soft.

"What if you die when no one's looking?" tried the hitman one last time.

"I won't."

Reborn wasn't the type to just give in, but Ienari was different.

Before he knew it, he let himself fall into the embrace of another sky, and he fell hard.

"I can't afford to lose you."

Ienari bent over in pain. He didn't have much time until another headache knock him out, knuckles white as he balled his fist in an attempt to not claw out his own burning throat. "And I- hnng… can't afford to lose everyone else… So I won't die…"

Pulling his fedora down to cover his expression, Reborn sighed in defeat. "… Aright. 3 minutes. Then I'm coming back in to check on you."

More than enough time.

"O-Okay…"

Reborn disappeared through the white screen without another word, leaving the brunet alone in the infirmary. Maybe. Had Reborn really left? Ienari wasn't so sure since his intuition fucked up his other senses. He heard the door clicked.

Ienari let out a shaky sigh. At least the spartan tutor finally left him alone.

Now, if only he could find his damn phone.

.

Hayato didn't dare to move when he felt a gun pressed against the right side of his skull. One moment, he left to the other room with the complete medicine cabinet to get whatever painkillers he could get his hands on. Next, Reborn pointed a gun at him, a lone finger ready to pull the trigger. Very slowly, Hayato closed the door.

Reborn looked angry, all set to kill. Hayato paled in fear.

Was he too late? Oh, God, please no.

"Reborn-san… I-Is Jyuudaime-"

"Shut up. He asked to be left alone. Leave."

The hitman jerked his head to the side, urging Hayato to leave. Of course he himself would leave too. Ienari wold hate him if he didn't honor his words.

3 short minutes. No biggie.

Hayato, though reluctant, understood his boss' request. He was in no position to argue.

Both of them were about to leave when a whimper from Ienari stopped whatever it was they were doing.

"N-Nii-sama…"

.

Ienari thanked the whatever god above when fe found his school bag laying conveniently on the floor beside him.

His shakily stratched his hand into the bag and pulled out an orange flip phone.

Not many knew he owned one in the first place. Nobody bothered to check or ask. Not Reborn. Not his guardians. Not even his own mother. The only who knew were Naito Longchamp ( after the 8th Tomaso boss bothered him to get his phone number for a month ), and of course the person who gave the phone to him on his 10th birthday.

Ienari tried leveling his breaths, but the pain was too much. Hopefully, his speech wouldn't be too affected by his embarrassing gasps and moans. The last thing he wanted was for the other person to get the wrong idea, which happened way too many times in the past.

His thumb dialed a number he memorized long time ago.

Beep.

B-

-"Hello?"

Ienari's reply came out too weak. "N-Nii-sama…"

-"Nacchan! I'm glad you finally called after all these years!"

God, how Ienari hated that voice, though it sounded exactly the same as his own. Of course it would. The person on the other side of the line was his brother. Twin brother in fact.

Nobody needed to know that. Nana never mentioned his brother's name after his brother left home at the age of three. After he left, Nana acted as if the other twin never existed. Iemitsu was worse.

The blond idiot of a father insisted that Ienari was an only child, saying that the so-called brother Ienari played with for the first three years of his life was all a figment of childhood imagination. Ienari would've believed it too if it weren't for the terrifying 'gifts' his brother sends him every once in a while. Not to mention the torture he received when his brother actually visits.

The other twin, Sawada Tsunayoshi wasn't a good brother by anyone's book. Ienari had all the rights to hate him, and many reasons to back up his blunt dislike.

Unfortunately for him, Tsunayoshi was the only one who, by some weird alien/supernatural magic, was able to tame Ienari's oversensitive intuition. Ienari wasn't sure how Tsuna did it. Tsuna just… did.

-"But for you to call me willingly… It means you're in trouble?"

"Y-Yeah, Nii-sama… S-Something is going to happen… I just know it…! I… I- hnng-!"

-"Nacchan… Do you want me to come home? We can stop the 'game' for a while. It's okay. I'll-"

"NO! I… I mean… no… You don't h-have to- ahh-…!"

Ienari clutched the side of his head, consciousness slowly fading away. He knew he was at his limit. Without any energy left to talk, he willed whatever power he had left to stay awake.

-"… I understand, Nacchan."

Tsuna sounded genuinely sad. He looked forward to visit Ienari, but even his own brother didn't welcome his presence.

-"But you know… Everything is going to be fine. I know you'll be fine. You always had been, ne? So whatever happens in the future, it will be alright. I promise. I promise…"

There it was. Tsuna's magic.

Simply hearing his brother saying those words made Ienari's pain much duller. With the cloud in his mind cleared, he could breathe again.

The brunet let out a deep sigh as he hugged his phone close to his chest. Despite his massive hate for his brother, Tsuna always made him feel light and warm inside, as if he could fall into an eternal sleep without worrying about regrets and whatnot.

A rare smile of relief ghosted itself on his pale lips.

Before his consciousness slip away completely, he heard was a soft goodbye and short beep, letting him know that the call had been ended.

.

They couldn't believe what they just overheard.

Ienari had just made a phone call to someone he called 'Nii-sama'. By the way Ienari said the name, 'Nii-sama' was someone close, disturbingly intimate. That wasn't the tone he used for his friends or even his two older brother figures.

Nii-sama.

Nii-sama.

Nii-sama.

Could it be that Dame-Ie had an older brother, possibly a brother by blood…?

.

Somewhere in a small bakery, Tsunayoshi put down the receiver back to its place. A tired sigh escaped his lips.

"I should've known this would happen…"

Sawashiro Tsunayoshi stared at the orange-jeweled ring on his finger. His sky flames danced inside the gem in an uncontrolled hunger, begging to be released.

Two days since he received the memories from a doomed future of their current timeline.

Two days since Ienari and the rest of Vongola's 10th generation returned from their trip to the future.

Two days before Enma's transfer to Namimori.

No wonder Ienari's intuition acted up…

Tsuna frowned. If things went according to his parallel self's memories, then Ienari would break if he learned of Iemitsu's action. Who wouldn't hate you when you're related to the murderer who slaughtered their family?

Good thing Tsuna finished his part in the whole mess. He promised to interfere only when things get too out of hand. The rest was up to Ienari.

The store bell chimed beautifully in the peaceful air of the shop, signaling the owner of a customer-

"Tsuuuu-chaaaaaan~! I'm home~!"

Or not.

The white-haired teen made his presence known by throwing himself on top of the unsuspecting brunet. Tsuna casually sidestepped and smiled a little when the albino's face kissed the hardwood floor.

"Tsu-chaaaan…! Why did you dodge?"

"I'm open to normal greetings, not full-blown body slams." Tsuna replied, fingers twitching to punch the albino in front of him.

"Like a kiss?"

"The urge to murder you is strong, Byakuran."

The one known as Byakuran pouted. He snaked his arms around Tsuna's waist and hugged the brunet. Funny how the smaller teen fitted perfectly in his arms.

Tsuna returned the hug with a quick pat on Byakuran's back before pushing the other away, faint blush visible on his cheeks. "… But a kiss doesn't sound too bad. I'll think about it."

"Mmm! I'm glad to be back in your arms, Tsu-chan… A week away from you feels like forever…"

Byakuran had been away on a business trip for their small bakery for an entire week while Tsuna stayed to run the shop. Breads and cakes don't bake themselves.

The ring on Byakuran's ring finger shimmered when their hands touched, similar to how the arcobaleno pacifiers work. He loved it when their rings glowed a soft orange, letting him know that Tsuna was there with him.

"And Byakuran…?"

"Hmm?"

Tsuna pulled away to look at the albino dead in the eye, lips twisting into a wicked grin. Byakuran felt a shiver down his spine.

"Care to tell me why you're working for Gesso in their efforts for world domination ten years from now?"

To Be Continued.


A/N : Woot woot! Watch me as I start another story without finishing my other 2 sto- ( kicked by the crowd ) QAQ). I AM SORRY, PLEASE STOP KICKING ME.

Also,

- This is a Reborn x Ienari ish. Nobody is going to admit it. Of course, Tsuna is going to be a piece of shit and make the ship sail no matter what.
- This will have a one-sided-ish 10027. Tsuna isn't the romantic type, but there's no denying Byakuran is extremely important to Tsuna.
- Tsuna is one hell of a nightmarish brother. So chaotic. OOC GUARANTEED.
- Pairings is up for debate. I'm just going to wing it… unless… you guys have anything specific you want to see? ( within reason )
- Will edit this along with my other stories if I find the time.

Special thanks to my mum for telling me the sheet separating the beds in hospital wards are called screens.

Until the next chapter!
