A/N: Before anything starts, I'd like to thank everyone who's been reading each chapter! Your comments make me really happy and I'll try my best to make my stories more interesting! (Er, hopefully I don't mess up the whole thing in the process :X)

"Oi, Tsuna! Tsuna! If you don't wake up now, I'll be training you 14 times a week!" Reborn threatened his student, hoping that his student wouldn't be so out of it and wake up to his friendly help. Who would pass a chance to get stronger?

"Reborn, if you threaten him some more, I'm pretty sure that he would be too afraid to regain consciousness." Shamal sighed, though not reproaching the hitman. He was in no position to do so, after all. Besides, Reborn had his ways of taking care of his students.

Reborn merely grinned, lowering his fedora slightly. He had a very good idea of how Tsuna would react.

Tsuna abruptly sat up, staring wildly ahead.

Reborn smirked. "See?"

Shamal smiled and shook his head, amused.

"E-eh? What happened?" the bewildered brunet voiced in confusion. Why was he in a bed in the infirmary? It didn't make sense.

"Stop stuttering, Dame-Tsuna. Or would you rather I get you to stop by-" Tsuna's frantic shake of his head told him everything he needed to know.

"So," Reborn sighed, "What happened?"

"Haha," Tsuna began rather nervously. "Well, I guess I freaked out too much because of Shamal's reaction. He is counted as a hitman, and specializes in these. Anyway, after I explained it to him, my arm got really itchy." Tsuna desperately hoped that Reborn bought his lie.

"Itchy to the point that you fainted? How very interesting!" Reborn and Shamal thought, with a tinge of sarcasm.

Tsuna cleared his throat. "Well, anyway, what's wrong with me?"

Reborn's tiny smirk was still on his face, but he was definitely having a grave mood now. It gave off this really creepy feeling, which certainly did not bode well.

"Let's just say that you're currently incurable. Dame-Tsuna, it's very obvious that you're a weakling, so I'm going to ask you this once. Will you be alright? Or I could get Shamal's mosquitoes to- "

"No, no, it's fine!" Tsuna inwardly shuddered. Shamal didn't even know his disease, so how was he going to be cured? Who knows, he might start suffering from other things...

"Alright. Time to get back home!" With that, Reborn bounced off, leaving Shamal and Tsuna behind.

Shamal, who had been silent all this time, spoke. "Vongola Decimo, you know very well that I don't treat men. Your condition is unstable because at the moment, there is no way to cure you. As a doctor and because you are Vongola Decimo, I'm giving you anything you need. I believe it's alright if I give you a mosquito to prevent your itchiness."

It was not common that Shamal would treat others with such respect, except those he truly admired. In this case, Shamal held pity for Tsuna, and to ensure the head of the Vongola would not fall. For the past generations, Shamal and his ancestors had been serving Giotto and his descendants as doctors when they had serious injuries, poisoning or diseases.

Their lust for women was somehow similar.

BESIDES that irrelevant piece of information, Shamal was being very generous at the moment.

Tsuna was obviously lying about the itchiness, so he declined with a little smile, though he did promise to come back if he ever needed help.

Well, he doubted he would, unless Reborn allowed him to, though that meant his Dame title would stick forever.

Tsuna ran home hurriedly, for fear of the thunderstorm waiting at home. One would be Lambo and I-pin wrecking the house, and Reborn waiting for him *ahem* very patiently. With a lot of things to brood over, he focused on getting home in an absent-minded state, half-knowing what he was doing.

It didn't help that as soon as he opened the door, he was kicked in the face by his tutor.

"Itetete! Reborn, were you trying to kill me or something?" Tsuna yelled, though feeling more annoyance than the pain, which he had long-grown accustomed of. He started to nurse his poor nose as he entered the house.

Surprisingly, nobody else was home. Reborn explained that Nana had brought the two youngsters out, together with Kyoko and Haru. It seemed that Reborn was being awfully nice to him that day, but that was until he found two high piles of books on his study table.

"Because this is your holiday, I'm giving you some light studying to do." The brunet stared at his tutor in horror, accentuating his feelings which were now "WHAT THE HECK?" Holidays did not mean studying. Holidays did not mean homework. Holidays did not include training. Holidays included relaxation, fun and games! DEFINITELY NOT STUDYING.

Honestly, Reborn must have a screw loose to have such a weird definition of "light". Two huge piles of books of Japanese and Italian history, and more Italian, French, German, Russian and English books to study were out of his radar of "light".

"Dame-Tsuna, I'm perfectly sane. Thanks for your compliment." God, now he's reading my mind? Tsuna sighed exasperatedly in his mind, not exactly glad that his privacy was being breached.

"And I cannot read your mind. You're too easy to read, like always." Reborn replied, reading his mind again. "One last thing. Akira and Sho have been sent back to Italy for now, since you have your guardians with you. Now then, get to work. You have to finish these," he gestured to the books, "by the end of the time you are staying in Japan."

Tsuna gasped and quickly got to work, taking the first book on top of the first pile and flipping through it to see how many pages it was. Meanwhile, Reborn was long gone to do more of his research, and finding out more information through his sources.

Tsuna was getting extremely tired and could feel his eyelids drooping as he read the text before him in boredom. It was about a rather boring book about psychology which he had to think long and hard about. Adding the fact that the book was in English which he wasn't good at, his brain was going to explode from all the information and thinking. Sighing deeply, he controlled the raging headache by temporarily stopping all thinking progress and felt the throb which reduced, little by little.

He glanced at the digital clock at the corner of his table and noticed it was rather late already, so he decided to turn in, which he did so after wearily staring at his books for a second.

Reborn woke him up the next morning in his usual manner of using a large hammer, which Tsuna easily dodged with his enhanced intuition which had been trained through dangerous situations and vigorous trainings with his tutor.

"What? I don't have to go to school today since it's Sunday! What's the point of getting up early?" he half-whined. His precious sleep was now cut short, and to reiterate his point, it was a holiday.

"Mama said that she's going out with Kyoko and Haru today, so you have to cook your breakfast and lunch yourself. She left already." Tsuna got up, realising that instead of the usual time he woke up, it was actually 10 in the morning already. He went to the bathroom to refresh himself and brush his teeth, and as soon as he got downstairs as quickly as he could, he was dealt with another blow by Reborn, which he almost blocked entirely, though it got him on the cheek, causing a minor scrape.

"Dame-Tsuna, I'm hungry." He stated matter-of-factly.

Apparently, Reborn had told Nana that since Tsuna now knew how to cook, it would be better if he just cooked instead of relying on his mother all the time. Quote, "Tsuna is now a mafia boss, so that means he should have the survival skills which obviously include cooking."

Tsuna often helped out in the kitchen, but he had never cooked anything more than ramen, rice and some simple dishes. Hopefully, Reborn wouldn't start complaining about his poor skills. He was rather out of touch as in his 2 years out of Japan, he had a cook to provide him with his meals.

Hurriedly, he cooked the rice and whipped up some eggs and vegetables he found in the refrigerator and served it. Thankfully, Reborn made no attempt to chide him for his speed nor the food, which tasted alright, by his standards, though nowhere near his mother's standard.

"Today, you're free to do anything you want to. Tell me if your wrist starts to get… itchy." Reborn smiled solemnly as he finished his last egg. Tsuna forced a tiny smile as he remembered the absurd lie from the day before.

"Fine."

Hearing his student's agreement, Reborn put down his fork and disappeared out of the house, probably to gather more information. Tsuna sighed and brought the plates to the kitchen to wash.

I haven't seen Kyoko-chan or Haru since I came back. I'd better ask Mum about them and probably go shopping with them or something after school tomorrow. He continued to wash the dishes while wondering what he was going to do later. Call up Gokudera and Yamamoto to chat? Go jogging? Train? Or perhaps-

Argh. I suddenly feel dizzy… The plates in front of him began to move, though Tsuna was sure that he wasn't swaying but standing straight. Quickly, he pressed a soapy hand to his forehead and steadied himself. Damn… what's happening? A raging headache was clearly surfacing slowly, and he ignored the throbbing in his mind to focus on standing straight which, in itself, was becoming a task. He washed his hands and dried them, and staggered to his bedroom to get some rest.

It had to be the effects of powdery substance, because he was healthy. He knew that already. Which meant that the substance had to be of very high-technology to be something more than just… powder. This would imply that the Karuno family had developed a technology which was superior to the Vongola. This wasn't the time for a holiday! Of all times, why now, when I'm having my break? Tsuna groaned as his headache intensified. It was fortunate that he was already resting in his bed, or else he would have hurt himself while stumbling for his room.

He had to contact Giannini without Reborn knowing! His pride would not allow it if he was unable to do anything on his own. Reborn would definitely scoff his attempts since he was inexperienced, which Tsuna did not doubt. It was always "Reborn to the rescue!" in such matters. This time, though, he would prove that he, Sawada Tsunayoshi, was able to handle these situations. He had accepted his fate as a mafia boss, so he would do all he could to protect his family.

All of a sudden, the throb in his mind died down and he opened his eyes. He hadn't realised that he'd closed them in the first place. It was starting to infuriate him, the way families would hurt humans like themselves just for the sake of power and positions. This was just like how Byakuran wanted power, though simply on a smaller scale. Either way, it was wrong!

Wearily, he reached for his mobile phone and dialed the number to Vongola Headquarters.

"I need to speak to Giannini."

LINE BREAK_

By the time Tsuna was done discussing some matters with his technician, it was already lunchtime. He didn't feel like moving, but if Reborn came back to see him slacking off and not doing anything productive, he'd be a goner.

He made a few simple sandwiches and started studying the books which Reborn had given him, his mind on ways to track this family and their purpose. Could it be that they wanted to take over his family to be the strongest, or simply to prove their worth? A very perplexing concept which he couldn't understand…

"Tsu-kun! I'm back with Kyoko-chan and Haru-chan!" Nana's voice rang loud and clear as she opened the door.

"Tsuna-san!" Two voices chorused, and Tsuna instantly recognized as his female friends' – Kyoko and Haru. His mother had already confirmed that.

Smiling excitedly, he ran downstairs to see his friends, eager to get away from his troubles and books. Instantly, the three friends started chatting about their school life and anything that came to mind. They hadn't seen each other for a long time.

Tsuna was thankful that Haru had gotten over the fact that he was not going to marry her when they grew older, since she had started babbling about a certain man she had seen the day before. Otherwise, he would have to deal with her hanging around him all day.

"Tsuna-san, there was this super handsome man that I saw when I was walking home after going to the grocers! He had long black hair, and some markings on his face! He is really, really handsome! Guess what, he banged into me- " and on and on she went, discussing her new crush. Tsuna inwardly rolled his eyes as he heard her rambling on. Out of politeness, he did not stop her.

Kyoko smiled gently as she listened to her friend speak about another man so excitedly, and giggled at a few places. After all, they were at the age where these problems would start to surface. For some, it would be bliss, but for others it would be all but a painful memory.

It seemed that time flew by as the three laughed at jokes and things that happened in the past and all the experiences that the normal students had, which Tsuna was glad to hear. The girls were equally excited to hear about Tsuna's training, though if they were to experience it themselves, that would probably be a different matter altogether. Before they knew it, the sun was down.

Reborn had mysteriously re-appeared in Tsuna's room all of a sudden, though he picked up on Reborn's slight killer intent instantly. He's gotten better at detecting killer intent. Reborn smirked as he called for the three to have their meal downstairs.

Lambo and I-pin had been playing outside, which was why there had been no disturbances earlier on. Obviously, since it was time for their meal, everybody was back in the house. The house, which had been full of I-pin and Lambo's laughter in the past, was now full of laughter and chatter, which Nana had certainly missed.

"Mum!" Tsuna suddenly piped up, having thought of something.

"Hmm?"

"Do you know what Dad- "

Ring. Ring. Ring.

Tsuna raised his eyebrows at the untimely interruption, but this topic wasn't that important at the moment, so he chose to ask again some other time.

He walked over to the telephone and answered it.

"Hello, this is the Sawada Residence."

Silence followed for a second.

"Gokudera's badly hurt."

A/N: I've been influenced by this anime I'm watching, so I'm pretty sure that my style has changed a bit. Sorry for that, and this chapter is mostly explanation and not action. Sorry about that. This is the best I can think of at the moment. The next chapter would be about Tsuna in school, so there will be more interaction between characters. By the way, I… kinda forgot what Kyoko calls Tsuna, so forgive me if I'm wrong… *scratches head nervously* Should I make the plot a tad more complicated? Other than the problem of this family attacking…(mwahaha chaos) Hm… *tears hair out* ARGH!
