I just want to say something before starting this story and chapter. For those of you who do not like YAOI , I suggest you turn back NOW! And if any of you have problems with this, please tell me and I will try to do something about it. I don't know if there is a story here about Tsuna jumping for parallel worlds to parallel words, but if there is, please let me know. The idea came to me when I remembered a lot of people doing fan fictions about Tsuna ending up in a parallel world, and I thought 'Hey, why not make a fic about Tsuna jumping from world to world?' the idea came to me while I was day dreaming in my Math class. I sincerely apologize to my Math teacher for never listening to her class, but you can't really blame me. The class is fucking boring.

Well, on with the chappie! Please leave a review as well!

Chapter 1

When you ask someone from Namimori who Sawada Tsunayoshi was, you'd be given strange looks, disbelief, and sometimes, outright laughing out in your face. I mean, who wouldn't know of the name Sawada Tsunayoshi? And if they were kind enough to at least stop laughing and give you an answer, they would say he was the most pathetic and scrawny looking boy they ever saw, or others would still laugh but is decent enough to tell you that Sawada Tsunayoshi was the most useless teen they ever saw. Some would say that the boy would amount to nothing in his life, seeing as the boy was terrible in physical sports as well as academics. And so, he was given the nickname 'Dame-Tsuna' because of how pathetic he was. That was the life of Sawada Tsunayoshi, wake up, go to school, be laughed at, be tripped , be bullied and it was a cycle that repeated for the whole fourteen years of the boy's life.

But everything changed after the boy received the devil in disguise as a baby who announced that he was going to become his tutor and train him to become the most powerful mafia boss of the most powerful mafia organization from Italy and the whole world. Tsuna learned that day, never to laugh at the baby since he would just get bullets flying to his head, a ten-ton hammer to any part of his body, and downright kicking . Tsuna never got why Reborn loved to kick him at the back of his head. It was like there was magnet planted at his head and attracts the hitman's foot. Sometimes, he even finds the hitman kicking his face.

After the 'small' incident with the hitman, he found himself being thrown into the world of mafia, fighting against the bloody disciplinary leader, which if anyone finds out, he'd be turn into minced meat, a bomber from Italy who was after his blood, who then became like a loyal puppy to him that he sometimes found it annoying, a pineapple-headed illusionist who puts sexual innuendos in every single fucking sentence, but just shrugged it off as him being creepy, a trigger-happy man who loved to call everyone trash as well as his group of insane members, that Tsuna still loved no matter what because they were family, and then a marshmallow obsessed freak who tried to kill him, who evidently becoming allies after everything, started calling him 'his' marshmallow, a red-head that blamed Vongola for everything, then became his best friend…and more.

Tsuna had met a lot of people in the four years Reborn was with him and he had grown from a wimpy and spineless kid, to a beautiful and smart young man. He was now a beautiful eighteen year old young man. This of course, this did not go unnoticed by his friends, Varia, Millefiore and Shimon included, which then lead to everyone fighting for something he never knew, Hibari saying 'He'll bite him to death', Mukuro saying 'He'll take his body, Reborn saying 'He was his student to be tortured, and other's joining in, to which Tsuna found really weird, but shrugged it off as his friends and tutor, as well as ex-enemies, being weird again -never knowing the double meaning behind the words- but he still loved them despite their weird behavior.

Yet no matter how much he loved his family, he really hated them right now, especially Byakuran and Reborn as he stared at the figure in the mirror. He then looked at the piece of paper clutched between his hands and read it again, hoping that everything happening was a dream.

Dame-Tsuna

If you're reading this right now, it means that you're now in a parallel world. This was something that I wanted to try for so long, so I did it, and of course, with the help of Byakuran. It was hard to bribe the marshmallow-freak, so you better be thankful, Dame-Tsuna. You're in a parallel world right now and this is for your 'training' You'll be going from dimension to dimension to investigate the Vongola of that world and report back, with the help of Byakuran from the world you're in. And don't worry, I might send someone to visit you once in a while, so enjoy the 'you' of the other worlds~!

With lots of love, XOXO

Reborn

P.S Don't die, Dame-Tsuna.

P.P.S You better have a report of the other world

P.P.P.S Try the espresso out, Will you?

Tsuna looked back at the person staring at him in the mirror, and of course, let out his unmanly shriek.

"HIEEEEEE!"

xxXX00O00XXxx

Okay, okay…So he was in a parallel world right now and all he had to do was investigate the Vongola of this world. That sounds simple enough…If it wasn't for the fact that Reborn was involved! And besides, he knows nothing of the Tsuna in this world! 'Reborn! Why!?' Tsuna thought that he might have pissed a God off somewhere. No, scratch that, he thinks that he murdered a God somewhere around his life and this was karma's pay back. Tsuna slid down the bathroom wall and let the tears flow down from his face.

"Tsuna!"

Tsuna almost choked on his saliva when he saw the person that came in the room. 'Shit, please tell me I'm dreaming. Shit, Shit, Shit, Shi-'

"Tsuna! Are you okay!? I heard you scream. I was worried" the person trailed off as he cupped Tsuna's cheeks with both hands, forcing Tsuna to lock gazes with him. "Tsuna…Are you okay?" asked the person unsurely. Tsuna carefully took in the person's appearance. 'Blonde gravity-defying hair, Sapphire eyes…It is him' thought Tsuna as he looked up at the person, eyes pleading and glistening with tears. "W-w-why?" he asked. The person looked at him in confusion. "Tsuna…What are yo-Whoa!" but never got to finish his sentence as Tsuna abruptly fainted in his arms.

Giotto sighed as he looked at his little brother's body. His eyes scanned the frail figure of his brother; ghost pale skin, loud and sharp, almost jagged breathing, sweat trickling down his forehead, brown faded scars decorating his brother's pale complexion, accompanied with different variety of life-threatening injuries, and bandages wrapped around Tsuna, almost looking like a mummy. Giotto's eyes looked downwards, taking on a more shadowed and angered look

Well, it had been almost eight years since he last saw Tsuna and the only time he went home, which was today, was because of the news that his brother almost died in an accident. How long has it been since he visited his brother? How long has it been missing his brother's warmth and acceptance? Eight years, it's been eight years and yet, never had he once forgotten Tsuna. He never had forgotten to think about him. Every single day of his life, his brother's health was always on his mind. Things like 'Is he eating alright?' or 'Does he have friends that care for him?' always popped up in his mind at the most random times.

Ever since Giotto was young, he valued his brother, Tsuna, more than he valued his own life. His brother was everything to him, starting from the day his brother was born, to the years he spent taking care of Tsuna was he grew up, to the first little steps his brother took, and to the part his brother started to smile; Giotto enjoyed every moment of it and he would never regret having Tsuna as a brother. He could and would, never regret having Tsuna as a kin. Tsuna was his pride and that will never change, ever.

However, Giotto didn't know if he regrets leaving his brother behind. Despite the good intention behind him leaving and doing everything he can for Tsuna's safety, Giotto still managed to make one of Tsuna's greatest fears come true because of this. And truth be told, he didn't know what was worse.

Giotto sighed tiredly, carefully picking up his brother's body and placed him on top of the hospital bed. He then gingerly put the blanket on top of his brother and sat down on the right side of the bed. Giotto looked at his brother's peaceful face, as if the incident a few days ago never happened. A tiny smile crept onto his face. 'Tsuna's really strong, isn't he Giotto? Your little tuna-fish grew up and became stronger' His hands unconsciously moved by themselves; left gripping Tsuna's right hand and right brushing his brother's behind his ears and caressing Tsuna's porcelain like cheeks. His eyes softened, feeling his brother relaxed in his touch. 'But, you're still the same kind Tsuna I knew'

xxXX00O00XXxx

Giotto jolted awake at the sound of the doors being opened. He twisted his body around and his eyes met his right hand man's solemn looking ones. Feeling his hyper Intuition ringing, he couldn't help but swallow the lump in his throat seeing the other's faces.

"Hey guys? Why the long faces?" he asked, smile strained and voice hoarse. The other's(His parents and the doctor) felt pity towards Giotto, knowing that the man loved his little brother. It was G who stepped up first, eyes completely void of emotion, his magenta irises and stared directly down at Giotto's own sapphire eyes. "Giotto, I'm sorry" he whispered gently, but his muscles and expression told Giotto contradicted his gentle tone. Despite his calm demeanor, inside, he felt lost, infuriated, guilty, and every other negative emotion he could think of.

Giotto took a deep breath, trying to calm himself down as he looked up at G. "Why?" Giotto never regretted asking that question more than anything he ever did.

"Tsuna, your brother…has amnesia"

'Tsunayoshi-kun'

Tsuna fluttered his eyes open, blinking dazedly when bright light invaded his vision. He brought up his right hand, trying to block the rays shining down on him. He groaned, sitting upright as he looked around his surroundings. 'It seems you're awake' Tsuna looked to his right, where his ears picked up the voice. A familiar white-haired albino greeted him, a playful smile tugging on his lips approaching Tsuna.

"Byaku…ran?"

The man, who seemed to be Byakuran, smiled wider, humming as he neared Tsuna. His violet irises lit up in childish curiosity, sparkles shimmering in his pupil. Tsuna tilted his head in confusion. Why did it seem like this Byakuran knew nothing about him and was looking at him like he was the most interesting in the world. 'This is kind of creepy…' he thought, slightly spooked out by the white-haired albino in front of him.

The said albino leaned in closer to Tsuna's face, a few inches away from Tsuna. "You're really different from this world's Tsunayoshi-kun" he said, smile widening even further as he circled around Tsuna, examining him. Tsuna tilted his head even more, question marks popping out of his head. "What are you saying, Byaku-chin?" asked Tsuna with a small grin on his lips, knowing the person in front of him is Byakuran, just a different Byakuran. However, Tsuna didn't sense any ill intent from him, and his Hyper Intuition told him that this particular Byakuran was just like his Byakuran back at his world.

And, over the years, Byakuran had gotten really close with Tsuna, enough for the man to call Tsuna "Tsu-chan" and for Tsuna to call the albino "Byaku-chin" It was quite entertaining seeing the baffled faces of his friends when he started calling Byakuran that, and somehow, all of them demanded that they wanted a nickname as well. It was weird to say the least, but Tsuna knew that his family wanted to be called by a nickname as a sign of family affection. Well, all of them demanded in their own way. Gokudera started sulking because his precious Tenth didn't call him by a nickname, so Tsuna started calling him 'Haya-kun' Gokudera, however, still will never and still does not call him by his name, saying that it was disrespectful to his 'Tenth'

Yamamoto turned out to be a surprise though. The teen's smile turned upside down and Tsuna really didn't want to be reminded of 'the' Yamamoto from before. Seriously, it was like comparing the baseball maniac to a possessive and sadistic Reborn, and that wasn't very pretty. So, after much thought, Tsuna started to call him "Ya-kun" It was quite awkward at first, seeing was Tsuna had never called anyone by a nickname. But it seemed to please the baseball player a lot that Tsuna didn't really mind as much anymore, but sometimes, people got the wrong idea that it became unbearably awkward and not to mention embarrassing, but whenever Tsuna would stop calling Yamamoto by his nickname, the man would sulk; so, Tsuna just had to get use to it. Yamamoto just continued on to call Tsuna by Tsuna.

Ryohei was the same, just plain old Onii-san. The same goes for Lambo and Chrome. But the said girl demanded after a few days to call her 'Nagi' Tsuna, of course, agreed. He could never say no to Chrome, and the girl never really demanded anything from him. And besides, it was just this once she did demand, so Tsuna really didn't mind. But Tsuna, as the shy, bashful and polite boy he is, had to put a formality. And so, 'Nagi-chan' was formed. Chrome just kept on calling him 'Bossu' saying that it was Her own nickname for him. Tsuna smiled and walked away, missing the smile Chrome had when he patted her head.

Hibari was a different matter though. The said man walked into his office and demanded not asked, since Hibari Kyoya does not ask, and demanded Tsuna to call him by his first name, Kyoya. However, Tsuna was really frightened seeing the murderous look on his Cloud guardian, couldn't really bring himself to say it that he ended up with a tonfa in his face. If Tsuna wasn't Tsuna, he would've thought that his Cloud Guardian was sulking, but sadly, Tsuna is Tsuna, so he did thought his Cloud guardian was sulking. So, to make it up for him, Tsuna added a little twist into Hibari's name. 'Kyo-kun' he called him. Tsuna was really embarrassed at first, but seeing the small upward tilt of Hibari, it was worth it. Hibari then called Tsuna 'usagi' to which he never really got why. Actually, he was embarrassed calling his family by childish nicknames, but it seemed to please them a lot. Well, he guessed that it was definitely worth it seeing his family's smiles.

Mukuro found out after a two-week mission that Tsuna started to call everyone by a unique name. Tsuna, being a descendant of Vongola Primo and having Hyper Intuition, immediately thought up of a name for Mukuro, something telling him behind his mind that if he didn't, the man would have a really big tantrum and possibly destroy the Vongola Mansion because even Hibari had a nickname. So, Tsuna just made up a really quick name for him, actually quite surprise that Mukuro liked it. 'Muku-tan'

Well, back to the point…

Byakuran looked surprise by the nickname that Tsuna called him. "Byaku-chin...?" he asked with wide eyes. Tsuna nodded his small smile widening. "That's what I call you in my world" he replied softly, standing up and stretching his arms, grunting as he did so. He sighed in content, facing the Byakuran of this world and gave him a bright smile. "Is that alright?"

Byakuran still looked shocked, but nodded eventually. He smiled. "It's alright, Tsunayoshi-ku-" "Tsu-chan" interrupted Tsuna, eyes boring into Byakuran seriously. Byakuran raised an eyebrow. Tsuna, sensing his confusion, smiled wider. "Call me Tsu-chan. It feels weird if you don't. " he started, chuckling a bit. "I guess Byaku-chin and I got used to calling each other by nicknames that it starts feeling weird when he doesn't call me by my nickname" he explained. Byakuran smiled in understanding, walking towards a white couch placed in the middle of the white room, gesturing for Tsuna to follow him.

"And I am guessing that the Byakuran of your world calls you 'Tsu-chan'?"

Tsuna nodded, walking along side with the other Byakuran. "That's right." Byakuran hummed in thought, before looking down a Tsuna from the corner of his left eye. He then sat down, Tsuna plopping down at his left. "But I'm not the Byakuran of your world, you know? I could be very different from him and may even turn out a genocide killer that can very well kill you" he whispered, eyes narrowing. Tsuna seemed to freeze for a moment, muscles tensing before sighing and relaxing. He turned to look at Byakuran, a small but accepting smile gracing his lips.

"Still…you are Byakuran, my world or not. You are my family and you will be treated as one. I don't care if you try to kill me, I know you won't. Even if you do, I will still accept you…" he countered, eyes flashing bright amber. This took Byakuran aback, but Tsuna wasn't finish. "Besides, you tried to kill me in my world, succeeding." Again, Byakuran was surprised by this." Even if it was my future self you killed, you still succeeded in killing me. But I knew that you still had good in you. Besides" at this, Tsuna looked up at him, resolve and determination shining in his eyes. "Everyone deserves a second chance, whether you are enemy or not. And that means you as well, Byaku-chin. You are family, and that is all that matters"

Byakuran was really taken aback. This boy was really different from the Tsunayoshi of this world. The Tsunayoshi of this world was someone who had the same amount of forgiveness as this one, a powerful sky was well. But he was timid, too shy, and too quiet. He was reserved to himself, never talking to anyone else and always running away. He was a coward, and as much as Byakuran hated it, the Tsunayoshi of this world didn't hold the same amount of determination and resolve as this one. This Tsunayoshi however, held a great amount of patience, determination , and confidence. He had power in his words, an aura of command, an aura of authority, words that can make people listen to him. And Byakuran had never met such a powerful person in his entire life.

He smiled, nostalgically. 'I did. I just never saw his potential' he thought, an image of a timid, brown haired boy smiling at him. 'Maybe, Tsunayoshi-kun of this world isn't that much different from him' His eyes looked back to the small smile of the boy. 'Not at all different'

xxXX00O00XXxx

"So, Byaku-chin, what was the Tsunayoshi of this world like? I need to act like him so people won't notice the difference right?" asked Tsuna as he took a sip of the Earl Grey prepared by the Byakuran of this world. Byakuran laughed. "That's right, Tsu-chan~ I forgot to tell you!" he exclaimed, Tsuna sweat dropping at his familiarity with the Byakuran of his world. 'Byakuran will forever by Byakuran…' he thought with a small smile. He set the cup of tea down on the small glass table in front of him.

After Tsuna and Byakuran's conversation about Byakuran potentially being a genocide killer, Tsuna found out that this world was Byakuran's mindscape. Which freaked him out since being in other people's mindscape was like invading their privacy, right? Well, Byakuran didn't really mind so Tsuna relaxed a bit. And it was really fun as well, since you could think up of anything and it would just appear in front of you!

Byakuran leaned back, sighing in content as the sweet sensation of Earl Grey slid down his throat. He paused for a slight breath, seeming to think of what to say before nodding and setting his cup of tea down as well. "Well…" he started, turning to face Tsuna. "For one thing, he's really shy. Not like your average shy, but more of a 'Get within a thirty feet radius near me and I'll start blushing and stuttering madly' shy" he stated bluntly. Tsuna sighed. "Somehow, that was like me when I was fourteen" he mumbled. He looked up at Byakuran, kind of pissed that Byakuran was still taller than him. "What else?"

Byakuran hummed. "Also, the you of this world never went to school because of your brother's request. And as you know, your brother is Giotto, the tenth boss of Vongola" he continued, gently picking up his cup of tea and taking a sip again. Tsuna raised an eyebrow at this. "That's kind of odd" he commented, Byakuran tilting his head in question. "In my world, Giotto is my ancestor and the first boss of Vongola, while I'm the tenth boss of Vongola."

"Just different timelines, Tsu-chan" Tsuna nodded in understanding. He picked up his cup of Earl Grey, stopping mid-way. Byakuran looked at him curiously. "What's wrong, Tsu-chan?" he asked. Tsuna turned to look at him, eyes wide. "So…does that mean Reborn isn't my tutor?" he asked, hopeful. Byakuran laughed at his expression, patting Tsuna's back gently and wiping the tears that formed in his eyes.

"Yes Tsu-chan. He Reborn isn't your tutor." Tsuna's eyes widened, smiled growing. "However…"started Byakuran smirking. " Reborn will come and live with you because your brother, Giotto came home and will stay with you guys. Meaning, Reborn will end up tutoring you and forcing you to go to school. He already applied you to Namimori High school, so, you will have to go to school" Tsuna's face became crest-fallen, Byakuran laughing loudly. Tsuna glared, his soft features making it look more of a pout. "You're not helping, Byaku-chin…" he gritted out as Byakuran laughed loudly.

"Aw~ Come on, Tsu-chan! Besides, there's worse to come!"

Tsuna's glare intensified. "What?" Byakuran smirked. "Reborn accidentally thought you were a girl and applied you as a girl for Namimori high. So, practically, you have to cross-dress because it's too late to change your gender on your application form. It was sent in, and I'm guessing they already put it on school records. They're probably just waiting for your picture now."

Tsuna fell onto his knees, feeling his manly hood being stripped off of him. "Y-You're k-kidding, right?" Byakuran patted his shoulder in fake pity. "Good luck" Tsuna was about to cry. He really was. But it seemed that there was more trouble for him. "Oh, and by the way, Tsu-chan…There's something else…" Tsuna glared at Byakuran, eyes glistening in tears, creating the illusion of beautiful sunlight shimmering in Tsuna's caramel brown eyes, Byakuran freezing a bit seeing his eyes. "And what's that?"

Byakuran smiled. "You have amnesia. So you have to pretend you don't remember anything. And don't worry about Giotto's Hyper intuition. I'll help with that. But for now, Good Luck~!" he purred as he disappears in white mist.

"BYAKU-CHIN!"

END

Omake: How Reborn bribed Byakuran

"Byakuran. I want you to send Tsuna to another world for training" said Reborn as he neared him, stopping at the table in front of Byakuran. Byakuran raised an eyebrow, stopping mid-way from stuffing himself with marshmallow. "And why's that, Reborn-kun?" he asked curiously, leaning back into his chair and plopping his feet on top of the mahogany desk.

Reborn smirked. "For my entertainment" Byakuran sighed. "But it takes too much work~ And besides, that means I'll be away from 'My' Tsu-chan~! That's even worse you know!" he whined, pointing an accusing finger at Reborn. Reborn popped a vein in his forehead hearing Byakuran claim Tsuna as 'his'. 'The hell. If anything, Dame-Tsuna belongs to me-No, No, NO' Reborn glared mentally. 'Reborn, you are not a hormonal teenager in love. Get a grip on yourself!'

Reborn took a few breaths, Byakuran watching in amusement as the hitman looked like he was trying not to maim Byakuran on the spot. Reborn glared. "First of all, Tsuna isn't 'yours' Byakuran…" he started, smirking after he finished the sentence. "And second…You'll get something special. Something that no one in Vongola has right now…" he grinned sadistically, seeing Byakuran's ears perk up.

Byakuran smirked, eye's narrowing as he leaned in, taking his feet of the table and propping his elbows after, using it was leverage. "Oh? And what is that?"

Reborn smirked. He then grabbed five pieces of paper, showing it to Byakuran whose eyes widened, a rosy blush dusting his cheeks. The pieces of paper were photos of Tsuna as a baby, a toddler, him cross-dressing when he was young, him hugging a large bunny teddy bear, and last but not least, Tsuna's eighteen year-old self sleeping peacefully in the garden of the Vongola mansion.

"These" Byakuran made an attempt to jump over the table and grab the contents from the hitman's hand, failing as he fell flat on the ground with Reborn stepping on his back, cocking a gun to his head.

Byakuran glared. "Reborn…Give me them and get the fuck off me" he hissed out, Reborn's smirk widening."Not until you help me. So, will you so it?"

Byakuran didn't even need to be told twice. "Yes"

Reborn smirked, he wins…

Terrible or Good? Please tell me your opinions!
