Ciaossu~! This is the first chapter of Magic in Mafia, a crossover of Katekyo Hitman Reborn and Harry Potter. This story is like my own versions of other fanfics so sorry but I'll try my best to do it.

I do not own KHR and Harry Potter but if I had the chance I would.

The story takes place in the Goblet of Fire.

7:00 AM at Tsuna's house.......

Tsuna was sleeping oh so soundly until a familiar kick and yelp was heard....

"Wake up Dame-Tsuna" Reborn said landing a kick on the poor brunette's head.

"OW! Reborn, can't you just wake me up normally" Tsuna said clutching his head in pain.

"If I do that, it wouldn't be fun and you should've seen that coming even though you're sleeping, you really are still Dame-Tsuna" the infant said.

"Hey, you know that I gotten less clumsy and I'm doing good at class as well" Tsuna replied.

"For me, you're still Dame-Tsuna. Now get up your gonna be late" Reborn said jumping off his bed.

"Fine" Tsuna said wanting more sleep.

Actually Tsuna was really becoming less clumsy and is doing better at class.

After 2 years when they defeated Byakuran in the future, he matured and became more responsible and he finally accepted to become the Vongola Decimo after persuasions from a certain hitman (*cough* Reborn *cough*).

Now Tsuna is 17 as well as Hayato and Takeshi, Kyoya, Ryohei and Mukuro are 18 and Lambo is 7 and is starting elementary school. Tsuna, Hayato and Takeshi are in 4th year middle school and the rest are in high school.

A lot of changes had happen after their trip. Tsuna as you know already less clumsier and more responsible. He is also calmer now and can ignite his flame at will.

Hayato can control his temper now than he use to but he can still be destructive and leads Tsuna trouble but his loyalty and admiration for his Tenth never left him though Tsuna wishes that Hayato didn't have to call him Juudaime.

Takeshi understood that the mafia is no game and is serious but that carefree smile never left his face laughing and being ever so cheerful and getting shout by no other that Hayato by trying to calm him are by laughing so much.

Ryohei finally stopped persuading Tsuna to join the boxing team and he matured a bit but he still is extreme as before, maybe worse but he still was like an older brother to Tsuna.

Lambo is the one that matured the most. He cries less often and was more respectful. He even calls Tsuna now Tsu-nii. He got better at making friends and being humble but his fights with Hayato still continues because he's possessiveness at Tsuna which Hayato will not allow so it ends up destroying wherever their fights happen.

Kyoya, unbelievably, left Nami Middle and entered Nami High. His reason was, well, to bite older herbivores. He is now the head prefect of Nami High. I'm feeling sorry for the high school students now.

Mukuro, after many negotiations and help from the ninth, was free thanks to Tsuna. You couldn't imagine the joy Chrome felt when she heard this. Mukuro agreed to become the Mist guardian for freeing him but still says that he'll take control over Tsuna and destroy the mafia but Tsuna said he'll be willing to take the risk.

Back to the story......

"I'm off to school" Tsuna said eating a toast and rushing to the door.

"Bye sweetie" Nana said.

"Bye Tsu-nii" Futa, Lambo, and I-pin said timorously.

"Bye" Tsuna replied.

"Bye Mama" Reborn said hoping onto Tsuna's shoulder before he got out.

Tsuna opened the door to see Hayato and Takeshi in front of their house bickering again about something. They stopped fighting to look at the brunette and greet.

"Ohayo Juudaime" Hayato said bowing his head in politeness.

"Mornin' Tsuna" Takeshi said wearing that oh so cute smile.

"Don't you dare speak to Juudaime that way base-ball freak" Hayato said angrily.

"Ohayo and it's alright Gokudera-kun" Tsuna said. "They're still the same" he thought smiling lightly.

"Dame-Tsuna, if this keeps up, you'll be late" Reborn reminded them.

"Reborn-san is right Juudaime, let's go" Hayato said.

"Hai." Tsuna said running with Hayato and Takeshi to school.

They reached the school even before the bell rang and was greeted by some kouhai. (1)

"G-Good Morning Tsuna-sempai, Hayato-sempai, Takeshi-sempai" they said obvious of the small blushes in their cheeks.

Actually, in those two years that Tsuna got more mature, girls noticed his chance not only in attitude but as well as appearance. Hence, the Tsuna fan club was born along with Hayato's and Takeshi's existing fan clubs.

"Good Morning" Tsuna said with that innocent, blinding smile which left the girls screaming like fan girls in their heads and blushing hard.

"Tsuna is a lady's man now" Takeshi said grinning suspiciously.

"W-What?" Tsuna asked shocked at what the baseball star said.

"What are you saying baseball-freak? Juudaime was already a lady's man" Hayato explained nodding in approval.

"W-Wait G-Gokudera-kun, that's not what I meant" Tsuna tried to reason.

"Haha, yeah maybe you're right. Takeshi said laughing.

"I know I'm right" Hayato said nodding his head in approval again.

"They aren't listening" Tsuna thought as he sighed in defeat.

"Ohayo Tsuna-kun" Kyoya said.

"Ohayo Kyoko-chan" Tsuna replied. "Things could get better" Tsuna thought

The day passed by quickly and now it was lunch. Tsuna answered many times and got passing marks on his exams. The teacher cried in joy at Tsuna's improvement over the years.

"Lunch finally, I'm hungry" Tsuna said as he laid on the rooftop.

"Me too" Takeshi added.

"Juudaime, do you want a rice ball?" Hayato asked with a puppy-eyed face.

"Sure" Tsuna said surrendering to that face Hayato had.

"Here you go Juudaime" Hayato said giving it to Tsuna.

Hayato was about to hand it to Tsuna until a certain infant took it and eating it in one bite.

"Reborn, that was mine" Tsuna said pouting at the infant.

"You were too slow" Reborn said drinking a cup of tea that appeared out of nowhere.

"Don't worry Juudaime, I have lots" Hayato explained smiling at Tsuna.

"That's not the point Hayato" Tsuna sighed. "What are you doing here Reborn?" Tsuna asked.

"For this" he answered pulling out an envelope from his jacket. "A letter from the ninth" he added.

"T-The ninth?" The three said together shocked.

"Yes and it's for you Tsuna, well technically, you and your family" Reborn explained.

"M-Me?"Tsuna whispered then gulped. What could the ninth want? Tsuna wondered.

Tsuna started to open the envelope and read the letter.

"Tsuna, it really is from the ninth, that flame proves it" Takeshi said with a worried expression on him.

"Ah... it is" Tsuna said nervously but calmed down to read the letter.

It says.......

Dear Tsunayoshi,

You and your family are to go to Hogwarts school of Witchcraft and Magic to participate in a contest called the Triwizard tournament as a request from the headmaster and my long time friend. You will go in disguise as the fourth school in the tournament with me as the headmaster. And I know you are wondering if magic is real, well, it is but only few mafia families know it. But keep in mind that you have a mission here; you shall protect a young wizard naming Harry Potter from a dark wizard named Voldemort. We will fly to Hogwarts at 12 noon after 2 weeks so get ready and inform your guardians.

Sincerely,

The Ninth

"W-What?" Tsuna asked shocked by letter.

"W-Wait magic isn't real, its just fiction (oh the irony)" Hayato added.

"Well isn't this exciting" Takeshi said obviously laughing but confused.

"Is this true Reborn?" Tsuna asked the Arcobaleno.

"If that is what the letter says, then it is. The ninth will never lie about this" Reborn replied.

"Your right, the ninth would never" Tsuna said.

"So tell this to the stupid-cow, Ryohei and Hibari" Reborn ordered.

"W-Wait Hibari-san as well" Tsuna afraid.

"Of course he's your guardian" Reborn said.

"B-But Reborn, he won't agree to come with us" Tsuna said stating the obvious.

"Your the boss, you should know how to handle your subordinates. On second thought I'll tell him" Reborn said changing his mind.

"Oh no, if Reborn's the one who'll do that, he might make a deal with Hibari that if he'll come, he can fight me" Tsuna thought wide-eyes.

"W-Wait Reborn, I..." Tsuna said but only to find the infant nowhere at sight.

"Reborn" Tsuna sighed in defeat "I wonder what it'll be like there?" He thought as he closed his eyes.

Kouhai- are younger class men in your school
