It's me again and I'm back much sooner than I had expected! Hello again! OH MY GOSH 60+ VIEWS IN A SINGLE DAY! HIIIIEEEEE! Thank you guys so much I love you all!

I tried my best to keep all of the characters as in character as I possibly could but seeing as this is my first story I might have made some people a bit OOC (especially Tsuna). This one is a LOT longer just like I promised. I have also decided to officially make this a weekly update on Wednesdays, so keep an eye out and please enjoy the story!

Chapter 1: Goodbyes and Strange Greetings

The next morning Tsuna regretted his choice of words greatly.

There he stood, alone in a dense forest in his new uniform climbing a ridiculous amount of stair to his new class. The car- if he could even call that thing a car- had left him there with direction from Reborn that his destination was at the top and they'd be there at the end of the day. Should have been easy but no. Instead he was walking for what seemed like forever, and only now after who knows how long found himself close to the top. In the distance he could see a barren plain of lush green grass and beyond that a rundown school building that if he was being honest was quite intimidating on the beautiful landscape.

Subconsciously he found himself wishing that Gokudera and Yamamoto were there with him. Heck, even Hibari or Mukuro would have been better than this. Any thing just to keep him from jumping out of his skin. 'How long has it been since I've been without one of them? Nonono, Dame-Tsuna! You can't be thinking like that! You've got a job to do. It's just school!' He shouted at himself as he wiped sweat from his brow. 'Still, that was… rough…'

Flashback

He hadn't known what he should have been expecting but when he'd answered the door at Gokudera's knock he'd been met with quite a sight. A sleek black limousine sat parked directly in front of his house. In addition to the very large vehicle were four suit clad men milling around the yard, and his intuition told him that those bumps under their jackets weren't just cigarette packs or lighters.

"Ohaiyo gozaimasu, Juudaime!" His silver haired friend all but shouted when he saw Tsuna's surprised face.

"Ohaiyo, Tsuna!" Yamamoto laughed from Gokudera's side. "Nice ride, you goin' somewhere fancy?"

"Ohaiyo, Gokudera-kun, Yamamoto. Y'all are here early." Tsuna laughed, grabbing his suitcase from beside the door and stepping out onto the walkway. He watched helplessly as his self-proclaimed right-hand-man's eyes widened in utter surprise. A nervous laugh crawled from the brunette's throat, he really wasn't looking forward to this part. "Jii-san has a mission for me. I'm transferring to Kunugigaoka starting today. I told Okaa-san to tell you guys if you came by, what are you doing here?"

Yamamoto set his hand on Gokudera's shoulder with his goofy relaxed grin as per usual. "Ma ma, the kid called me this morning saying that he had a surprise. Same with him. Guess this is it, huh, Gokudera?" He laughed.

'Reborn! What are you thinking?!' The brunette shouted despite his friend's cheer.

Tsuna could tell that Gokudera wasn't taking the news very well though. His shoulders were shaking visibly with barely restrained… anger? He couldn't tell since the shine in his eyes betrayed sadness rather than rage. Suddenly he whirled around, glaring daggers at Yamamoto. "Can't you see how serious this is, you baseball freak?! The boss is going away WITHOUT us!" For an instant Tsuna could have sworn that the Rain Guardian's eyes hardened and his perpetual smile faltered before returning to normal. And even then it looked a little forced. Then in a second green eyes met brown, making him flinch back in a second of uncontrolled fright. "Juudaime, please don't do this! At least allow me to accompany you."

"I wish I could Gokudera-kun, but I couldn't ask you to leave school like that. It's not right. You either, Yamamoto." Tsuna explained trying his best to placate the pair. "You have a game in a couple weeks right? You'll have to leave the team if you come with me and I couldn't ask you to do that." Now it was official. Yamamoto's eyes darkened and his disposition did a complete one eighty. The tranquil rain was now depressing. "Seriously, I'll be fine. Jii-san's taken care of everything and I'll see you at the game so it won't be too long."

No one said anything for a few minutes. None of the three so much as moved. There was an unspoken consensus between them… all of them hated this. It was strange and abnormal, they'd gone through hell in the past year they'd been together and to be separated was… unnatural.

Another moment passed. Then finally Tsuna felt himself get pulled into what felt like a crushing bear hug. Which it was when it was Gokudera Hayato the fanatic and Yamamoto Takeshi doing to hugging. "Fine. But you better visit, Juudaime. And we'll be coming by over the weekend. And calling-"

"Okay, okay, I get it!"

Despite his tone though Tsuna was happy. Happy that his friends didn't want him to leave; but most of all that he had friends to begin with.

With that Gokudera practically pushed him into the limo, despite Tsuna himself being very opposed to the idea. The whole time the silver haired bomber was shouting things like "only the best for you, Juudaime!" and "It's a gift from Kyudaime, you have to accept!". Eventually it worked and Tsuna found himself waving goodbye to his family ( Okaasan, Lambo, I-pin, and Fuuta) and Guardians as his armed escort brought him all the way to his current predicament.

'They're trusting me to handle myself. I have to live up to their expectations! Even if I don't want to be, I'm the Vongola Decimo. I've dealt with a lot worse than this. I'll be fine.' With that Tsuna sighed, readjusted his bag on his shoulder, stood up straight, and began his trek to Class 3-E.

...Only to wipe out as he tripped over his own two feet into the dirt path. 'Why me?!'

Meanwhile With Class 3-E

The room was eerily silent.

Not a soul dared to move, let alone speak as each individual fiddled silently with the triggers of their respective firearms. The nervous energy was almost tangible as the students mulled over the last few details of their plan. Homeroom would start soon meaning so would their newest attempt to complete their mission. In other words, the government sanctioned assassination of one yellow faced tentacle menace AKA their teacher.

Closest to the window a boy with light blue hair tied in pigtails on top of his head stared at his desk intently. Something inside him was bugging him. A tugging feeling in the back of his mind that he couldn't quite place, however a single thought came to mind. 'This isn't going to work. He would never fall for something like this.'

Sighing the boy tried to calm his rising nerves. Turning he glanced out the window toward the clear blue sky above. It was honestly ironic that inside was so cold on a gorgeous day like that. Then he saw it. A flash of light brown just beyond the treeline, yet before he got a good look at it the color disappeared leaving nothing more than green foliage and dark shadows. 'Huh, must've been a trick of the light…'

With Tsuna

When he'd finally pulled himself up off the ground he was happy to see his uniform wasn't filthy as he'd expected. After ensuring it wasn't damaged he brushed himself off and approached the building.

Before he even opened the door a man in a black suit and gravity defying hair similar to his own and a serious expression beat him to it. His body wanted to flinch back at the sudden expression, but his HI quickly reassured him. 'He looks scary, but he's much more kind than he lets on.' The man's dark eyes met Tsuna's and the result was immediate. All previous fear the brunette felt was gone in a flash replaced with a sensation of calm security, "Ohaiyo, sorry if I'm late, sensei." He explained quickly giving the man a quick bow.

"I'm not your teacher, not yet at least so there's no need for formalities. You must be the new student; Sawada Tsunayoshi, correct?" The man asked, eyes never leaving his.

"H-Hai."

The man's gaze scanned him quickly and Tsuna could only assume what he was thinking. After all he'd always looked dame, even if he'd toned his body a lot more in the past year. Oh well. It helps if people underestimate you, or at least that's what Reborn always said. A low sigh released from him. "My name is Karasuma Tadaomi, follow me. I'll show you to your class."

With that Karasuma turned and walked a bit further into the building, leaving a confused Tsuna just outside the building's threshold. Quickly Tsuna dashed to meet the man all the while allowing his HI to take note of his surroundings. The building was just as run down inside as it was outside. The windows were clean for the most part but a little old, you could see dust and water stains on the wood. The floorboards creaked in certain spots as sign of old age but Karasuma didn't seem to be nearly as bothered by that fact as Tsuna. The walls also were old and he was honestly surprised that the building was still standing. This was his new school?

Suddenly Karasuma stopped in front of a particular sliding door with the writing 3-E on the nameplate above the door. "This will be your classroom. The octopus should have started homeroom at this point so you'll have plenty of time for an introduction." The tall man's hand reached out for the door handle, intending to open it when a feeling of foreboding rushed through the Vongola Decimo, chilling his spine. Something was wrong.

"Don't open it!" Tsuna shouted rushing forward and grabbing the man's wrist. Karasuma stiffened and let out a startled sound at the boy's strong grip before the familiar popping of gunfire erupted from the classroom.

"Damn, get down!"

As fast as he could without his Dying Will Flames Tsuna pushed Karasuma to the floor and against the wall separating him from whatever threat was on the other side. After multiple attempts on his life in the past few months Tsuna had figured out how to handle these situations: get down and get out of the way. His normally warm eyes hardened and if you had looked closely you could tell his irises were fading from brown to their sharp calculating orange and a flicker of flame was forming on his forehead. Quickly realizing his slip Tsuna clenched his eyes closed willing the flames to quell and his eyes to return to normal. He could handle this without them.

At the Door with Karasuma

"Ohaiyo, sorry if I'm late, sensei!" A brown haired boy exclaimed almost as soon as he'd opened the door.

When he'd gone to meet the transfer he'd been surprised to say the least. The boy was tiny, about the same height as Shiota and the shorter girls if not shorter. His gravity defying hair was not helping his case. His eyes though were so wide and innocent that if he hadn't known better he would have assumed the boy was terrified; the only thing saying otherwise was the fact that the child didn't so much as flinch when he fixed him with a stern glare. Physically he looked weak. No muscles. No defining physical features (aside from the hair that is) and no visible scars or battle marks to signify any experience in combat whatsoever.

'What is the Ministry thinking?! This kid is not suited for this mission! He'll get eaten alive The Principal just notified us today of his arrival, but shouldn't they have known he was coming, dammit.'

"I'm not your sensei, not yet at least so there's no need for formalities. You must be the transfer; Sawada Tsunayoshi, correct?" He asked.

"H-Hai." Sawada-san stuttered. Karasuma took another moment to glance over him before sighing. 'I've got my work cut out for me…'

"My name is Karasuma Tadaomi, follow me. I'll show you to your class." Leaving the door open he turned and made his way down the hall to the Class 3-E door, all the while thinking of possible ways to toughen the new kid up once he took his position as PE teacher in a few days. Finally he stopped and looked to see that Sawada had managed to keep up. "This will be your classroom. The octopus should have started homeroom at this point so you'll have plenty of time for an introduction." He then reached out to open the door, ready for this interaction to be over with for the time being.

"Don't open it!" In a second there was a strong grip on his wrist holding him in place. A startled cry forced its way from his throat as the boy held him firm. Not even a minute later a flurry of gunfire sounded from the other side of the wall signalling the students had started an assassination attempt. "Damn, get down!"

One minute Karasuma was on his feet the next he found himself with his back to the wall and his head spinning, sitting on the ground. He must have hit his head on the wall. 'What the hell was that?' He thought. Once the vertigo faded and he no longer felt discombobulated he cast a glance at the transfer beside him. 'This kid is strong. And fast! How did he realize the gunfire was coming before I did?' The boy was tense, but not abnormally so. No, his legs were positioned perfectly to move in whatever direction was required, and his fists were clenched in a relaxed tension that was familiar for men conditioned for battle. His face was toward the door and away from Karasuma's line of sight but he could have sworn that the child was calculating his next action. 'Sawada Tsunayoshi, just who are you?'

Slowly the gunfire slowed to a stop. A few more pops and then it was over, aside from the sound of… rolling? Were those BBs? Why would someone be shooting BBs in a middle school classroom? Just what was Reborn up to?

"Sawada-san, I think it's over. If you would mind letting go…"

"Huh?" Tsuna turned. Sure enough there was Karasuma sitting behind him, his wrist still gripped tightly in his own. "HIIIEE! S-Sorry! I don't know what came over me!"

Quickly Tsuna released the older man, stood and stepped back laughing nervously all the while. 'I must have really freaked him out there for a second. This'll be awkward to explain…' He thought, depressedly.

Karasuma simply stood from the ground and readjusted his suit: Tsuna noted happily that it had avoided getting damaged in the commotion. "That was a quick reaction. You've got some mad skills, Sawada. Just where did you learn to move like that?"

Now that was not what he was expecting. Shouting, confusion, anger maybe. But praise and calm calculation. No way. "U-Uh, I have a good tutor. He knows some martial arts stuff and thought I should know a bit." 'More like he shot at me and blew me up until I could move fast enough for his liking. Reborn seriously has a sadistic streak…'

The taller man nodded, eyes distant as if thinking. "You've got a good tutor. I'd love to meet him someday." He said.

"S-Sure, maybe someday." 'You really REALLY don't.'

"Well, I do believe that your classmates are finished so let's get you settled." Finally Karasuma opened the door revealing a filled classroom. Kids were sitting in all the available desks aside from one and each of them wore a dejected look like they'd failed in something major. Tsuna didn't focus on that for long though considering there were three things he was preoccupied gaping at.

The blackboard was dented in several places and the desk had a clear plastic bag filled with pink BBs sitting atop it. The students also had firearms ranging from pistols to sniper rifles situated under their seats as if they were completely normal, which was rather disturbing. Both of these facts explained the sudden inexplicable gunfire, but the thing that confused him even more was the fact that at the front of the room was a giant, yellow… octopus alien in a professor uniform. 'WHAT THE HECK!? REBORN, WHAT HAVE YOU GOTTEN ME INTO?!'

The octopus thing turned to face him as soon as the door clicked open. His face was a strange sight with a wide, toothy grin plastered to it and eyes so small Tsuna barely saw them from this far away, but he didn't seem frightening. Just… weird. Like… really weird. "Ah, you must be our new addition. Nice to meet you my boy! Come in, come in, introduce yourself to the class. Thank you Karasuma for bringing him here, but if you wouldn't mind I have a class to teach."

'That thing is a teacher!' Tsuna screamed to himself as he silently walked forward and wrote his name on the board. When he turned back the door was closed and Karasuma was gone. 'At least he didn't ask too many questions…' "O-Ohaiyo, my name is Sawada Tsunayoshi and I'll be transferring into E-Class today. I-I look forward to learning with you all." He said giving them a nervous smile and a small bow.

Everyone in the room found themselves unconsciously smiling back at the small brunette. His smile was contagious and so innocent that not even Terasaka could resist his charm- though he and his friends were some of the only ones to resist actually expressing it outwardly. Some of the girls even blushed. 'Kawaii!'

"Thank you very much for your introduction, Sawada-san. Now do you have any questions before we begin class?" The octopus asked. Tsuna nervously glanced at the teacher with a look on his face that should have said everything he was thinking.

"U-Uh, ano, actually yes, sir. Um, what is going on?"

A moment of silence passed. Tsuna felt the heat of every eye in the room training on him as he shared a nervous look with his new teacher (?). Was he missing something?

The yellow thing looked down at him before speaking. "Ahem, I'm sorry Sawada-san, but I must ask did you get briefed before being admitted to this class?" He- Tsuna had a strange feeling it was a 'he'- asked.

"Uh, briefed? I'm sorry, sir, but I have no clue what's going on." Tsuna explained scratching the back of his head, hoping this awkward conversation would end and he could disappear into the group of new kids.

Another moment of silence.

"NANI!" Everyone- including the teacher- but the transfer shouted, looks of astonishment crossing their faces. Some even stood from their seats in surprise as their sensei's face turned BLUE and began sweating profusely.

Tsuna flinched back in surprise as he paled a couple shades in fear. 'Yes, I'm definitely missing something. Someone help me!'

And there you have it! Our little Tuna fish is officially a part of the E-Class! I hope you guys liked the length. It'll definitely be shorter than the next chapter which I will admit has been very fun to write. That chapter should be up next Wednesday hopefully, and if not it'll be the 27th (hehe... that was absolutely unintentional). Again I'm sorry if Tsuna was a little OOC with the swearing but I know that he curses every once in a while when he's in HDWM so I thought it fit.

Review and let me know what you think or any questions you have, because more reviews=more updates. I love hearing what you guys have to say and I know that it'll help my writing one way or the other. Please just remember to keep it classy!

Till next time
