Summary: Sawada Tsunayoshi, the Decimo of Vongola, at the age of 26, died. His guardians? Broken, saddened by the thought they couldn't protect the one that meant the world to them. What do they do?/ "... Byakuran, do it."

Chapter 1 - The Rain, The Cloud, and The Sun's Rude Awakening

Sawada Natsu, aka, the perfect son and person. To girls, he was the handsome and kind person. To guys, he was the goal and rival. In reality, all Natsu really was, was the protector of his weaker older brother. He showed his brother care and kindness he probably would never show others. Sure, he didn't actually show the care and kindness in public or in school, but at home, Tsuna was Natsu's top priority.

Sawada Tsunayoshi, the elder twin and the dame. To girls, he was nothing and to guys, he was a target. In his reality, Tsuna was actually pretty smart on his end. Unlike his brother who was all sport, Tsuna was all brain. He didn't show it though, he just didn't want to tear the popularity from his younger brother. He was born ill and is still weak, instantly having to sit out in PE. On special occasions will his coughing act up, but it wasn't anything too bad.

You wouldn't be able to even tell Tsuna and Natsu were twins unless told, reason being that they're fraternal twins. While Tsuna carried the brown hair and honey-brown eyes from his mother, Natsu carried the blond hair from their father and his eyes were a darker brown. Tsuna's hair was also more gravity-defying than Natsu's, which also made it fluffier. Natsu's build was also bigger than Tsuna's, making him seem more masculine than Tsuna's feminine build.

"Tsuna~" Speak of the devil. Tsuna cracked an eye open, glaring at his twin as he tried waking him up. "Get up or you'll be late. You don't want to be bitten to death by Hibari-senpai, right?" Natsu grinned and stepped back as Tsuna sat up quickly and hopped out of bed.

When Tsuna finished dressing, Natsu grabbed Tsuna's wrist and pulled him downstairs, making sure he wouldn't trip. In all honesty, Tsuna's clumsiness only came out from being weaker and not being able to distribute his weight evenly(which he managed to fix when they turned six, but every now and then he'll trip).

"Ohayo you two. Breakfast is ready." Nana greeted them in the kitchen, motioning to where two plates full of food sat innocently on the table. The twins nodded and sat down, quickly digging into their breakfast. "Your lunches are already made and are over there. Ah, I nearly forgot to mention, I called up a home tutor for you, Na-kun." She smiled at sat down next to them.

"A home tutor?" Natsu asked and Tsuna raised a brow.

"Hai, the flyer said that he'd make you into the leader of a new generation." Nana giggled, pulling out the flyer and showing it to the twins, who exchanged a shared look of disbelief and confusion.

"It could be a scam..." Tsuna scanned the paper again while Natsu nodded.

"You never know, Mom." Natsu added and Nana sighed.

"Too bad I already called. Oh well!" She smiled and the twins shared another look with each other. The doorbell suddenly rang and Tsuna got up.

"I'll get it." He walked off to the door before Natsu could protest. Opening the door, he saw a baby.

Reborn rang the doorbell and waited for the door to open. When it did, he expected Nana to answer.

Not him.

Not the one who he failed to protect.

Freezing for a second, he looked into those all too familiar but all too unfamiliar honey-brown eyes. He watched as the one who he'd die to protect slightly tilt his head.

"Are you lost, little one?" That voice. Reborn almost broke his emotionless exterior to hug the teen, but fought back the urge.

"Ciaossu. I'm the home tutor, Reborn." He introduced himself and regained his posture. Only to nearly break it again when he saw that smile that formed.

"Is that so?" He saw Tsuna hold up a finger and walk back in, only to come back, this time with Nana. "He says he's the home tutor." Tsuna informed Nana, who smiled.

"You're here earlier than I expected! Come on in!" Nana ushered the hitman inside and he saw Tsuna sigh and close the door. Reborn watched Tsuna walk back to his seat next to his twin and the two broke into a silent conversation with their eyes.

"Ciaossu!" Reborn greeted the family. Natsu looked Reborn up and down before looking at Tsuna, who shrugged. The twins turned to Nana, who was currently all smiles and joy.

"You're the home tutor? But... aren't you a baby?" Natsu questioned and Tsuna nodded.

"I am the home tutor, my age doesn't matter." Reborn replied, looking at the time. "You better get going before you're late." He watched the twins looked at the clock before one got a worried face and the other's eyes widened. Both twins raced to grab their things, but they didn't leave without saying goodbye.

"Reborn-kun?" He heard Nana ask, and in response, he looked up at her. "Watch out for those two, okay? Tsu-kun may be weak, but Na-kun is always there to look out for him."

"Weak?" Reborn asked.

"Ah, he was born weak and he gets ill very quickly." Nana informed him, a sad smile on her face. "He had to sit out on most of his childhood, but Na-kun was always there to cheer him up. I just hope one day, more people will be there for him."

Reborn smiled and took a sip of the espresso he pulled out of nowhere. 'Don't worry, Maman. Soon we will all be there for our Sky.'

While Nana and Reborn were having their conversation, Tsuna and Natsu were racing to the school grounds, trying to make in time. "Look! There's the gate!" Natsu grinned and Tsuna nodded, holding back a small cough.

"We made it!" Tsuna sighed happily as they ran through the gates just as the clock hit the mark. The twins watched as a few unlucky students were bitten to death by Hibari. But they froze when he turned to face them.

"Herbivores, if you do not start heading to class, I will bite you to death." He tightened his grip on his tonfas, but when he got a better look at the pair, his eyes softened a micro bit. There stood his Omnivore, the one who would par against him in strength but still acted herbivorous. The one who allowed him to do whatever as long as he'd keep it in check. The one he failed to be there for in his time, the packmate that vanished.

"S-Sorry, Hibari-senpai. Come on, Natsu." Hibari watched as the Omnivore tugged on his brother's sleeve, a sudden image of a bloodstained bed entered Hibari's mind and he froze. The herbivore nodded and the two began making their way to class.

Hibari shook the image out of his head as quickly as he could, and when he saw Yamamoto Takeshi walk through the gates late, all he did was walk over and smack the teen over the head lighter than he would've. "He's safe." Was all the prefect said before walking away.

Yamamoto on the other hand, stood there, frozen in place. If he looked close enough, he could see the receding back of his precious friend. Hibari was right, he was safe. Hell, he was alive! A smile formed onto Yamamoto's face, brighter than his usual ones.

Their Sky was safe and alive.

Hibari walked into his office and pulled out two files. Sawada Tsunayoshi and Sawada Natsu.

Name: Sawada Tsunayoshi

Age: 13

Gender: Male

Sawada Tsunayoshi is the older twin of Sawada Natsu. He has average academics and an unknown physical due to sitting out during Physical Education. It is known that Tsunayoshi has an illness that makes him weaker, which in turn, makes him sit out during Phys. Ed.

Name: Sawada Natsu

Age: 13

Gender: Male

Sawada Natsu is the younger twin of Sawada Tsunayoshi. His academics are poor, but he makes it up with his high physical. He is on the baseball team and is the second best player under Yamamoto Takeshi.

Hibari reread Tsuna's file before his frown deepened. "I need to tell the baby carnivore about this." Then Hibari blinked, "Well, if the baby carnivore is at the Omnivore's house, then mother omnivore would've told."

Hibari learned quickly back in their world that Sawada Nana is not to be crossed when it comes to her family. He saw it first-hand the beating she gave some assassins when they came to assassinate the Omnivore. She was, and most likely still is, a carnivore hiding as an herbivore. Just like her son.

Taking the files back to the cabinet, he sighed and walked up to the rooftop for a nap and to recap on what all has happened so far.

When Yamamoto entered the classroom, it took almost every fiber in his being not to jump onto Tsuna and hug him to death while crying. Instead, when he saw his Sky sitting at his desk staring into space, he smiled. He promised himself to go over towards Tsuna later and sat down in his seat.

It was hard for Yamamoto to pay attention in class. The whole time his attention was on Tsuna, convincing himself that this wasn't a dream and that Tsuna was actually right there, breathing and alive, and not lying on that godforsaken bloodstained bed.

In a parallel world, yes, but that didn't matter.

All that mattered was that their Sky was there, and soon everyone else too.

When Ryohei woke that morning, he didn't burst into his normal shouting. Instead, he marveled on how he was currently his teenage self. That didn't last though, he soon began his usual shouting of EXTREME and got into his jogging gear.

Kyoko, his younger sister, only sighed at his antics. "Nii-san, what's gotten you this excited?" She asked and Ryohei only laughed the question off, not telling her the true reason he was happy.

The true reason he was this happy, was that there was the small string of hope that Tsuna was indeed alive and safe, that he didn't fail in saving his Sky. The image still haunted the back of his mind, but he waved it off, grabbing that small string.

Running out of the house, Ryohei jogged to the school. When he saw Yamamoto standing at the gates frozen, he ran over yelling.

"TAKESHI!" He yelled and Yamamoto turned his head around to look at the white-haired teen.

"Ryohei!" Yamamoto's bright smile was all Ryohei needed to know about his little brother. "He's alive! I-I saw him!" Yamamoto told him and Ryohei stopped in his tracks.

"So... It extremely worked?" Ryohei asked and Yamamoto nodded.

"Judging by how Kyoya acted too, the three of us have our memories of that world and now we're all here. He's here." At Yamamoto's words, Ryohei broke into a huge grin.

"YEAH! THIS IS EXTREMELY GOOD!"

At lunchtime, Tsuna made his way to the roof while his twin went off with his own friends. Sitting down on one of the benches, Tsuna opened his lunch. But before he could eat, he saw the baseball star Yamamoto Takeshi walk over.

"Yo, Sawada! Can I join you?" He asked and Tsuna nodded.

"Sure, I don't see a problem with it, Yamamoto-kun." Tsuna scooted over and Yamamoto sat down next to him.

"You don't have to be so formal." Yamamoto grinned and Tsuna flushed red. "You can just call me Yamamoto, or Takeshi. We're friends now after all, right?"

Tsuna blinked a few times. 'What..? B-But... I-I don't deserve someone like him as a friend!' "A-Are you sure?" Tsuna asked and when Yamamoto nodded, Tsuna sighed. "Okay... You can call me Tsuna by the way." Tsuna smiled.

Yamamoto's mood brightened five times when Tsuna agreed to be his friend and ten times when he saw that smile. The smile of his precious friend who saved him from the darkness. Before Yamamoto could say something else, a little yellow bird appeared and snatched some sushi from Yamamoto's lunch.

"Hn, herbivores." The heard the prefect, Hibari Kyoya, say from where he sat on top of the small building on the stairs. The bird gave Hibari the sushi and Yamamoto broke out into laughter.

Tsuna on the other hand looked dead confused, 'What's with today!? First, an infant claiming he's Natsu's tutor, then Yamamoto wanting to be his friend, and now the demon Hibari is taking food from Yamamoto!? Who's laughing!?'

Seeming to read his friend's mind, Yamamoto chuckled and ruffled Tsuna's hair. Now, Yamamoto was assured that this wasn't a dream. Tsuna was real. More proof that this wasn't a dream was the pain he felt from Hibari biting him to death.

Tsuna smiled and laughed. Hibari smirked and continued to beat the baseball star into a living pulp.

After school, the three guardians met up. Earlier that day, sometime after lunch, Ryohei had his own run-in with Tsuna. "I still can't believe this worked..." Yamamoto leaned against the wall in Hibari's office. Ryohei nodded in agreement, currently rewrapping the bandages on his hands.

"But there is a small problem with him." Hibari said, throwing the two the file on Tsuna. After they read it, their cheerfulness disappeared.

"I remember him sitting out at times, but I didn't think it was from an illness." Yamamoto spoke softly.

Ryohei, on the other hand, had on a serious face. "You don't extremely think that this illness could be extremely connected to that poisoning?" He asked carefully and Hibari sighed.

"I thought about that possibility. There is a small chance that it is, but we'll have to hear from baby carnivore." Hibari sat down into his chair and Yamamoto looked up.

"The kid is here already?" He asked and Ryohei nodded.

"I extremely saw the kid earlier today during my extreme jog. We didn't talk though because he was extremely inside Sawada's house."

"Hn." Hibari began to clean his tonfa.

"Well, judging by that then, Hayato will be here very soon. Maybe he'll bring Lambo." Yamamoto smiled again and Ryohei laughed.

"I can't EXTREMELY wait for Octopus-head to get here."

"Quiet down herbivore or I'll have to bite you to death."

Outside the office door, there stood Kusakabe and a few other DC members crying because their leader was actually interacting with other people in a civilized conversation.

After dinner, Reborn followed the twins into Natsu's bedroom. "So you're going to be my tutor?" Natsu asked him once he and Tsuna were situated on the floor, Reborn sitting on the bed.

"Yes and no. My real reason for being here is to train Sawada Natsu-Sawada Tsunayoshi-into the tenth boss of the mafia family Vongola. It is the biggest and bloodiest mafia family and you are inheriting it from your I-don't-care-how-many-greats grandfather and first boss Giotto." Reborn pulled out the colorful family tree picture and watched the twins exchange a look.

"Aren't there other candidates?" Tsuna asked and Reborn began his explanation on why the Nono's children couldn't(all of them being dead except Xanxus who was frozen).

"Your father, Sawada Iemitsu, is apart of a side family called the CEDEF and is the external adviser, which crosses him out as candidate. Your brother would've been chosen if he were strong enough, but in the end, it left you." Reborn finished.

"Dad is in the mafia!?" Natsu exclaimed and Tsuna's eyes were wide. Reborn nodded and hopped off the bed.

"You should get some sleep. A good boss should never be tired." Cue an image of an older Tsuna at a desk asleep in piles of paperwork from an improper sleep schedule.

"O-Okay..." Natsu looked at Tsuna, who gave him an encouraging smile, before getting up.

"Goodnight." Tsuna walked out of them room and Reborn hit Natsu in the head with a ten-ton Leon-mallet.

Later that night, Reborn looked into Tsuna's room just to assure himself said teen was still alive and breathing. Walking over to the sleeping teen, Reborn gently ran his fingers through Tsuna's fluffy hair, making sure this wasn't a dream like Yamamoto kept doing earlier.

'Oh, when Hayato gets here later, it's going to be a blast. Literally.' Reborn thought with a small smile, hopping off of Tsuna's bed and returning to his hammock in Natsu's room.

End of chapter!

Two chapters in one day... I'm feeling a little generous.

Either way, here is Reborn, Yamamoto, Ryohei, and Hibari's reactions to Tsuna! Yay, he's alive and breathing!

Hehehe, well see you guys next chapter!

Bye!

:)
