Summary: What if Tsuna and his guardians are arcobalenos? What if Giotto is not born an Italian and thus takes up the name Ieyasu? And he led a peaceful life before his tutor came? And he has no idea that his friends are part of the Mafia? And what if Reborn and the other arcobalenos are the partners of Tsuna? And the tutors each have a pet? Arcobaleno!Vongola 10th gen, Adult!Arcobaleno, ill/abandoned!Tsuna, Decimo!First generation.

Note: It's just an idea I have that's stuck in my brain, like, for a long time. So basing on the number of reviews and likes (at least 10 of each, aww, so demanding), I'll see whether to continue this plot.

Two figures strutted down the dirty alley of Sicily. One, a tall teenage wearing a crisp black suit topped with a black fedora with an orange band. The fedora sat a green chameleon, which kept glancing around like its master. What were most noticeable about him were his curly sideburns. On the teenager's shoulder sat an infant. The infant had unruly caramel brown hair that stands at every corner, crazily defying the laws of gravity. His ears are covered with headphones labelled with the number '27'. He has a dusty orange mantle draped over him. His head sat a lion cub with orange flames and a transparent blue visor and white helmet. The helmet has the Roman numeral 'ten' under the helmet's jewel.

They walked past a couple; the male had an evil glint in his eyes, not that the two of them cared though. The male looked up and pulled away from his partner. The two figures walked to a shady looking building and open the door. They saw two males back-facing them while smoking. The infant pinches his nose and stuck out his tongue in disgust while the grown man remains unfazed. The two males recognize the shadow and spoke up. "Welcome. Reborn, Cielo." Reborn tilts his fedora in recognition while Cielo just waved. Just then, Reborn grabs his gun and points it behind him. Cielo turns around and clicks his tongue. "It's not a toy and you shouldn't be playing with one either." Cielo remarked. The man behind them paused in his movement and drops his knife. The man then shakily backs off and starts running with Reborn firing at him to make him go faster. Both of them look back into the bar and grinned.

"You know, you shouldn't be playing around and missing purposely when you aim at them. Although I must say it's quite amusing to watch them jump when each shot was fired." Chuckled Cielo. Reborn pushes his fedora up and glances at Cielo. "As if, sadistic."

"Who's the one that rubbed it on me?" Cielo spoke, trying to bare holes into the man. Reborn laughed as he watched his partner try to pout. One of the man coughed, getting the two's attention quickly.

"Have you got another mission?" Cielo nodded his head slowly.

"Where? Venice? Rome? -"

"Japan." Reborn cut of the man's questions. Behind the dark sunglasses, you can see the males' eyes widen. "So the old man has decided!"

~Japan, Namimori~

"Kaa-san... You don't have to wake me up that way! My ears are ringing from all those noises!" A blond boy with fluffy hair complained. A brunette lady puts her hands onto her hips and chides her son. "Then in what way will you want me to wake you up? Ie-kun... you're going to be late if you don't wake up..." The boy ruffles his hair and reached for the clock on his desk. He then tosses it onto the bed hastily as he runs out of bed. "Kaa-san! Why didn't you tell me sooner!"

The lady shrugs as she takes out a pamphlet from her light pink apron. "By the way Ie-kun, I have just called home tutors for you!" The bathroom door slams open, revealing a half-naked boy with a toothbrush in his mouth. Hastily, he removed the toothbrush and spoke with bubbles in his mouth.

"Byu whar? (1)" Barely understanding the speech, she answered. "This morning, I found this advert in the mailbox and called them immediately!" She flashes the paper she received to him. Scanning the paper, he shouted, "Baa ii saou lie a skar! (2)" This time, the lady does not understand and lifted an eyebrow. Ie-kun spits out the paste in his mouth and rinses them thoroughly. Repeating himself, his mother continues. "But your grade really needs help!"

He scowls and thought about his grades. Sure, an average score for all subjects being borderline. O-ho, I may need a home tutor. As if reading him, she spoke again. "They'll be coming after your school end so you better hurry. You're gonna be late soon!" Ie-kun runs out of the bathroom and dressed quickly, grabs his toast and stuffed his lunch into his bag. He opens the door and saw two red heads waving at him. He smiled and shouted into the house, "I'm going!" and he joins his two friends on the road.

Hidden in the tall tree branches, the two partners continued to look at the three friends, jotting down notes that both of them observe (more like Reborn. Little Cielo is sketching on his notepad rather then taking notes. Notes make his head spin). This is what is on Reborn's paper.

"Hm... Interesting. They thought you were dead, Cielo."

"No wonder if he does not think of me. Maybe my parents don't even remember me, Sad. Oh well, not that I cared." Reborn rolls his eyes and climbed down once the three boys are out of their sight. Cielo jumps down from in between the leaves and landed on Reborn's shoulder gracefully. They turned to look at the orange roof of the residence. "Let's go then."

"- And she just hired tutors without my consent!" Ieyasu complained to his two friends as they jogged to school.

"Well I think she did the right thing. Your grades suck." G teased. The other red head chuckled softly. Ieyasu's face turned beet red as he sputtered incoherent words, which his friends deemed 'ok' to dismiss.

"What I think is that you have to give them a chance. You never know what will happen." Cozart answered. G snorted loudly. "Right, Mr. Mature." Cozart shrugged off the insult.

"Err guys, let's talk more later on. We should first avoid the blood thirsty-looking Alaude who is tapping his foot impatiently over there!" Ieyasu pointed gingerly at a blond boy standing at the school gate, who is glaring at the three of them with his icy blue eyes. They quicken up their pace and walked into the school grounds, which broke into a cat-and-mice chase when Alaude started to chase them to class. "For being late, I'll arrest you!" All of them broke into cold sweat as they tried their best to run from the skylark and luckily, G snapped open the door when Ieyasu narrowly dodged the incoming handcuffs.

Ieyasu has always wondered why Alaude only aims at him with his weapons and ignores his two good friends. He is glad that he has this two friends because without them, he could roughly guess that by now, he would be carrying awful bruises on his skin. He continues to stare into space as his teacher explained the ten laws of indices.

"SAWADA!" His maths teacher shouted as the boy ignored him for three times. "Solve this and I'll let you and daydream go." The numbers looked like greek to him as he failed to understand the question. Scratching his head, he gave a rough guess. "Err... 5 to the power of 3?"

"Wrong. So that's detention for not paying attention in class." The class sniggered (girls cooed) at him. Only his close friends sighed at his behavior. Ieyasu continued to sit back down with his head hung low. He puts his head down and decides to ignore the rest of the lesson. Time flew past quickly and he finds himself sandwiched between his two friends in front of his house.

"Why do I dread going into the house?" He muttered. He turned to his two friends, hoping to get an answer. Only to get silence and cheeky faces which means that they could not give him any answers. He collects himself and steps into the house, braving all storms that he thinks will come.

Laughter erupted from the kitchen. And then embarrassing things about him from a female voice. And then teenage like voices can be heard from there too, talking too much like adults.

Staring at each other, the three of them decided to venture into the kitchen. "I'm back... Mom..." He trails off as he greets as he sees two new faces at the table. One teenager's face which is hidden by the fedora and an infant with hair like his, just brown. His mother's face is practically sparkling and flowers bloomed behind her.

"Uh... Mom, who are they?"

"Oh, Ie-kun, welcome back!" The two snickered and repeated the name calling, causing Ieyasu's face to turn red. His mother points at Reborn and Cielo. "The one with a hat is Reborn and the one that look so much like you is Cielo. They are your home tutors!"

Something clicked in his two friends as their jaws dropped. The two newcomers turned around and looked at them. This time, it's the red heads' turn to have sparkling faces. Ieyasu stares at them awkwardly. "Err guys? What's wrong?"

"It's Reborn and his partner Cielo!"

"Who?"

"Nevermind."

The teenage boy then puts down his cup of coffee (was that espresso?) and introduces himself. "Sawada 'Giotto' Ieyasu, am I right? I am Reborn and I will be your tutor in academics and sports. A pleasure to meet you, Vongola Decimo." The last bit was hushed, said behind his ear. Ieyasu just stood there frozen. The infant then pulled down his hood and glances at him too. He looked just like mom and him, like he inherited her eye and hair colour and got his unruly and spiky hair. "Hello Ieyasu, my name is Cielo and I'll be your home tutor on sports and another topic." Another topic? "Let's go to your room first shall we?"

Ieyasu scowled and begrudgingly led all of them to his room.

(1) You What?

(2) But it sound like a scam!
