Chapter 1

Snapped and threats

"Get up Dame-Tsuna" Reborn said with a smirk. "You have an important mission/meeting today remember". Tsuna jolted up. "Shit". Tsuna ran out the door and bumped into Gokudera and Yamamoto. "S-sorry guys, I didn't mean to run into you". Yamaoto just laughed with his usual bright smile (A/N he must have AMAZING jaw mussels from all his smiling) and Gokudera started to rant on about how he was a horrible right-hand man. "We better hurry, or we are going to be late to the meeting" Yamaoto said. The three ran off into the sunrise.

Time-skip - midway through meeting

"Wait, so are you saying magic is EXTREMELY real?" said a white haired boxer. "Why yes" Reborn said matter-of-factually. " And we have been asked by the professor of a magic school to come and help with the war" Reborn continued. "So you all will be going there but Lambo as he is to young, not to mention a pain, oh and Xanxus and the shark shall come along to". "kufufufu. Interesting" . "hn". "EXTREME". "If Mukuro-sama goes then I will go as well". "Now we are playing a magic game?". "Decimo I will help you on your quest in the strange world of magic". "W-wait HIEEEE" Reborn jumped onto Tsuna's shoulders "Come on, we need to get you your wands and books."

Hogwarts

Welcome back students and welcome new students. This year we will be joined with professor Umbridge who will teach DDA". As the speech went on Harry and the rest started to pay less attention until a strange announcement was made.

"Now this year we will have transfer students from Vongola school for the talented. I hope you treat the guest with respect as they may not be accustom to our type of school as theirs was based of muggle schools, they shall be arriving latter this week". The golden trio looked shocked. "Bloody hell, this has never happened before. I wonder how good they are at Quidditch". Hermione just stared. "That's what you're thinking about. Didn't you hear muggle school"

On the way to Hogwarts

"Scum, why the hell are we going to some fucked up school for weak ass trash?" Xanxus said as he chucked a wine glass at Squalo (note-they are in a plane) . "Why the bloody hell would I know you stupid excuse for a boss, go ask the little kid". Gokudera stood up and chucked some dynamite from god knows where at Squalo "How dear you insult Decimo, have you forgotten you lost to us you stupid shark". "Now, Now lets not fight we're almost there" Yamamoto said in his most calming voice.

"HIEEEEEE w-why did you throw a wine glasses at me Xanxus?" Tsuna screamed as he dodged the glasses. "I'm bored, so why not trash?". "You don't need to be so mean Xanxus" ninth said As they landed Tsuna ran out screaming. "HIEEEEEEEEEE, I don't want to die" As Tsuna was running he failed to notice he ran into the great hall we everyone was eating. Silence. Everyone turned to see a young boy who was around the age of 14 wearing muggle clothing who seemed so innocent and child like, he also seem to speak another language. Tsuna could hear Xanxus and the shark coming and slowly a vein started to twitch. It seemed they were mumbling about ways to make his life hell.

As Xanxus and the rest walked in the worst thing happened. The purest, kindest etc, etc mafia boss snapped. "YOU RETARDED SHITS, WHY IS IT WHEN EVER WE ARE ANYWHERE NEAR EACH OTHER YOU TRY TO KILL ME, GET OVER IT. I DON'T CARE ABOUT YOUR STUPID FUCKING EGO." Everyone (yes including reborn, Xanxus and Hibari ) looked at the boy shocked. Who knew he had such a potty mouth and could say all those swears in English. "Wow who knew you had that kind of language" the shark laughed. Tsuna sent him an evil glare.

"You must be the Vongola students, correct?" Dumbledore asked. "Why yes we are. It seems Dame-Tsuna snapped when you were having a wonderful dinner and for that I apologize. Dame-Tsuna you apologize too" Reborn said with authority. "S-sorry, I didn't mean for you to hear that" Tsuna studded. "Excuse me but may I ask where you head master is?" Umbridge asked. "Huh oh you mean Timoteo. He should be around here somewhere." Tsuna said with authority. Umbridge murmured something (Insulting) about their head master. All of a sudden the temperature went cold in the room and Tsuna looked pissed. "Excuse me miss-?" Tsuna started. "Umbridge" she replied. "Miss Umbridge but you do not know our head master nor to you have the authority to so I see no reason for you to insult him should you choose to again you shall make an enemy out of us, and let me warn you the last enemy of us ended up no longer looking human. So I suggest should you want to live NEVER insult him again you fucking piece of trash" The Vongola members turn to Tsuna and shivered. It seemed Xanxus has rubbed off on Tsuna. "For you trash that didn't understand the last part, the boy just said he would torture you and make you no longer recognizable should you continue to insult that stupid excuse for a boss" Xanxus stated with a smirk with his respect for the boy going up. Some of the group started to laugh and smirk while the others looked to shocked to do anything. "D-decimo are you alright" Gokudera asked with worry in his voice. "Why thank you Tsuna for sticking up for me" Timoteo said as he seemed to appear out of nowhere.

"Bloody hell, who the hell are these people. That kid seemed like the nice but just threatened at professor" Ron said with amaze in his voice. "What is so good about that, it's horrid" Hermione said. "Now let the shorting begin, we shall call your name and you shall be placed in you house. You house will be like your family an-" Professor McGonagall started until Gokudera cut in. "Bullshit it will be like my family. My only family is the Vongola" Gokudera started until Tsuna gave him a look say shut-the-fuck-up-you-idiot. "EXETREMLY sorry about that" Ryohei stated. "Just start this stupid sorting herbivore" Hibari said. "Very well" Professor McGonagall replied.

Tsuna, Yamamoto and Chrome made their way to their table the same as the rest but Gokudera who still followed Tsuna. "Excuse, Gokudera I believe, this the Gryffindor table not Ravenclaw" Hermione stated. Gokudera pulled out a cigarette and lite it. "Does it look like I give a cra-" Tsuna glared at Gokudera "Hayato, you of all people should know not to insult females. It's against the M code" Tsuna said.

He turned to Hermione "I'm surprise he didn't get put in Hufflepuff with his loyalty. You see he is very, VERY loyal to me and wont let me sit at a bloody table without babysitting me" Tsuna stated. Gokudera looked like a kicked puppy. "No tenth, that was never what I meant. I just want you to be safe." Yamamoto then came in "Then wouldn't you be at your table not ours?" Gokudera glared and started to pull out some dynamite. "WHAT WAS THAT YOU SWORD FREAK" everyone turn to them, while those from Vongola sighed. Tsuna sighed. "Does this happen a lot 'cause with the way you're all acting I would think so" Harry said as he turned to Tsuna. "Yea, just wait, it's about to get worse." Reborn who was sitting with Snape smirked. 'Looks like some fun is about to begin' Reborn thought as he saw the group arguing. "VOII, SHOW SOME SWORDSMAN PRIDE" "shut the hell up trash" Xanxus yelled as he pulled out his X-guns. "this is EXTREMLY fun". Tsuna stood up and walked over to the Slytherin table. "Kufufufu, what is it dear tsuna?". Tsuna stopped when he got to Xanxus (who was sitting next to Draco). "What do you want, filthy mug-blood?" Draco sneered. Tsuna grabbed Xanxus by the collar and through him across the room onto the teachers table. Everyone stared st Tsuna. "What the hell was that for trash" Xanxus roared in rage. "WHAT DO YOU THINK YOU WERE GOING TO BLOW THIS PLACE UP, NOW IF YOU DID AND DIDN'T GIVE ME PAPER WORK FINE. BUT YOU OF ALL PEOPLE SHOULD KNOW THE FEAR OF THE FUCKING PAPER WORK NOW NEVER PULL THEM OUT AGAIN YOU FUCKTARD" Tsuna roared. The Vongola all sweat dropped and started to laugh, chuckle and smirk until...
