AN: This story has been adopted by Cielo-Caelum! I'm so happy someone liked it enough to adopt it! -jumps in joy-

AN: Ugh, can't believe I forgot to put that the last Chapter one was a Harry Potter xover. Sorry about that guys. Still don't have a beta reader.

Disclaimer: I do not own the characters depicted in this fic.

AN: Also if you guys know a good beta reader or wish to be mine please tell me. I don't have a lot of time to proof read my stories and usually I just rely on spell check. Any way, I am amazed I managed to upload three things today...I don't usually have the time.

Also to Guest Reviewer of Chapter 1, I will try to make them longer but sometimes my muses just kinda stop and won't let me continue. -weeps- It's why I have so many chapter ones and no stories.

Battle Music

Summary: AU. Civilians may not have full access to their flames but that does not mean they can't fight with them...it just in a different way than the mafia. In a world where Battle of the Bands takes on a whole new meaning, how will Reborn train a Battle Musician Tsuna? BAMF!Tsuna, unfortunately it's only when he is performing.

A few centuries ago, it was discovered that humans could summon energy for low powered attacks or combined it to summon a large energy being through the power of music. The energies from their aura was soon classified into seven different categories: Orange, Blue, Purple, Indigo, Yellow, Green and Red. Though it has been noticed that some every now and then pop up with odd auras ranging in different variations of these colors whose abilities when summoned vary from those of that color as well.

The Rainbow Spectrum, as the scientists called it, brought forth a new generation of music and a brand new concept, Battle Musicians. Soon world leaders were stepping over one another to recruit these newly discovered weapons into their militaries, but were stopped because of a problem. Most of the attacks summoned by the Battle Musicians were rather weak and unless grouped together with a common goal and a full set of colors or many of the same color, they could not summon an energy being to fight for them. There was also the problem of how the attacks were summoned in the first place. The individual had to have a love for music and the passion needed to manifest the attacks in the first place. Along with being able to play for a long time if the military wanted any results, which would involve the individual standing out in the open for a long period of time without protection. And it was shown that certain individuals could only produce attacks with one instrument, many of which were not portable and just plain ridiculous for a battle situation. Really who was going to lug around a grand piano if the user was unable to produce attacks with a portable keyboard?

There was also the problem of getting a full set of Colors or a large group of one Color to work together, Orange Auras were rare and hard to find while many of the other Colors would not work together unless there was an Orange in the Band. And because of the conflicting personalities some Colors had given the individuals of that Color, well it was hard to get a group of a single Color together for very long. Blues and Yellows were easy to form Bands with but Colors such as Purple or Red were not easy to work with in large Bands. There was also the fact that certain Colors could wield their Music better through their voice instead of their instrument such as Indigos, Greens and Oranges.

So the military completely scrapped the idea of having their own Battle Musician armies. Though they did recruit those that had portable instrument and strong auras if the Musicians applied to the army. But with the public knowledge of the Rainbow Spectrum and their effects on music, a new concept came an old idea. Battle of the Bands, where Bands of Colors or Sets could compete for a grand prize, which included touring the world to battle in more music tournaments. Individuals all over the world began to band together to compete as the grand prize, usually a large sum of money, was enough to set them for life, be it fame or fortune.

This also lead to the forming of Crews, a gang formed around a strong Band that controlled set areas in countries and regulated the music, tournaments and forming of bands in that area. Some were benevolent as they believed that everyone had the right to the wonder of music, others though were ruthless, stomping out any rival band in the area they controlled or absorbing them into their crew. The government did nothing to stop this as they were already busy dealing with what they considered more serious matters, such as 'actual' gang violence, drug trafficking and the sort. They did not realize what the impact of Crews had on the youth of today and how the Rainbow Spectrum of Colors was held in such high regard that many students and young adults worked themselves to the bone to be able to even manifest a single attack with their music. Schools found demands from students and parents alike for more budgeting toward the Music departments and students petitioning for School Bands so they could participate in the Tournaments without a need for a sponsor.

When the Mafia learned of this all finally, it was much too late. Flames were public knowledge though they went by a different name and the information had already spread so fast that it would take teams upon teams of Mists and hackers to be able to wipe the information from everything, which would only buy a small amount of time before it would happen all over again. They were just lucky the Vendicare worked with the Vongola to tamper with the information each country's government had about exactly how strong the attacks could be and detoured the world leader's away from using Battle Musicians in battle. It was amazing that it hadn't caught on that the Battle Musicians that did apply for the military seemed to disappear and all information pertaining to them was wiped. Many retired Battle Musicians found themselves pressed into the Mafia to boost their ranks, or married off to Mafioso to do the same.

Though many mafia families had their eyes on a rising Orange (Sky) Battle Musician, who was dominating the Singles Tournaments and refused to join any existing Band. The Battle Musician was only known by his stage name, 27 and powered through many competitions in Japan with powerful attacks and was said to be able to summon a color beast, or energy being, without the need of a band. No one knew the true identity of 27 as his face was always covered by a blank white mask with the number 27 stamped on the right cheek in bright orange and the rest of him was hidden behind his many outfits, mainly consisting of either oversized hoodies with the hood pulled up over his hair and ripped jeans or a long hooded cloak and suit depending on the event.

All anyone knew was that he was a young male ranging from 14 to 18 and possibly still in school given which tournaments he enters. Many wished to find out who this young sky was and recruit him or even possibly kidnap him, but his location was unknown and it seemed no one could get a lock on him, no matter how hard they tried.

It would surprise many, both civilian and mafia, to learn that the Mysterious 27 was really middle schooler, Sawada, Tsunayoshi. Or as those in Namimori knew him as Dame-Tsuna. After all who would connect the cool and aloof 27 to the clumsy no good Tsuna?

Certainly not the World's Greatest Hitman; Reborn, who was on his way to Japan to train Dame-Tsuna to become the Vongola Decimo. My, My, won't he be in for a surprise? That is if he ever finds out.

AN: What do you guys think? Should I continue this as its own story? Or is someone interested in adopting it?

And I know its kinda rough but as I stated I have no beta at the moment.

AN: This story has been adopted by Cielo-Caelum! I'm so happy someone liked it enough to adopt it! -jumps in joy-
