Author's Note: Yes, I am still alive. I have had an endless supply of bad events over the past few years, my brother's death hit me really hard and I lost the drive to write. Now I'm back and after going over all of my stories I felt that I needed to give this story a major re-write. The plot will stay the same but after finally watching Yu Yu Hakusho past the first saga I have added more characters and I now feel that I have a better grasp on them. This story will be Au after Harry Potter and the Order of the Phoenix and it will be Au after the Dark Tournament or episode 66 of Yu Yu Hakusho. I'm hoping to update all of my stories after I have re-done this one as well as added a fifth chapter; this all depends on how much my son drives me crazy (the terrible twos was aptly named). Fingers crossed my faithful readers, and thanks to all who have reviewed and put up with my lack of updates.

Chapter One: Truth will out and an escape.

From the moment he arrived in the wizarding world, Harry was playing the part they all wanted. Everyone believed that Harry Potter was a naïve young man, who willingly followed the manipulations of Albus Dumbledore. Unknown to them all, Harry trusted no one especially after the overheard conversation between Dumbledore and the Minister of Magic at the end of his first year. It becomes a bit disconcerting when at the age of eleven you find out that two people of power have orchestrated you life from the moment you were born, even down to the death of your parents.

Dumbledore's grandfatherly attitude never effected Harry to begin with, but to find out that the senile old man was casting silent compulsion spells on you whenever he laid eyes upon you makes for a very ticked off young man. Even worse, is knowing that Dumbledore had sent him to the Dursley's knowing exactly how he would be treated, and encouraged it by paying them out of his own inheritance. But most of this was unknown to him at that point in time, as the years went by he learned more of the manipulations and plans that Dumbledore had put into motion concerning Harry and all around him.

Payment towards his supposed best friend to befriend him in the beginning was what hurt him the most. Knowing that Ron had only befriended him because of the money offered to him was more than he could bare. Hermione on the other hand had blatantly turned down any offers and befriended Harry simply because he saved her life in first year, their friendship grew into a familial bond after finding out about Ron's betrayal and Hermione found pleasure in using her considerable knowledge to make the red heads life at school most uncomfortable.

Ginny's role was even more un-seen and horrible. For a while Harry had been wondering why he had developed feelings for the youngest Weasley when from a young age he had discovered that he preferred the male variety over female. Fawkes, Dumbledore's Phoenix, was the one to enlighten Harry to the fact that the feisty red head was having a variation love/compulsion potion put into his morning pumpkin juice once a week for two years. Dumbledore was apparently getting frustrated with how long it was taking the potion to work, not know that Harry's magic was slowly filtering the potion out of the young wizard's blood stream. The process wouldn't have taken so long had the barmy old coot not put a bind on Harry's magic after he was born.

When a young and rather handsome looking boy had come up to him in his fourth year Harry had no idea who he was, never seeing him around the school. When he was told that the boy was the human form of Fawkes, Harry near fell off of his seat. Fawkes, apparently, was an eight hundred year old Phoenix demon who took human form only when necessary. He relayed everything that Dumbledore had ever planned since his battle with the Dark Wizard Grindiwald, his reasoning for not telling Harry sooner about all the manipulations and plans was that he was unable to transform due to a spell placed upon him by Dumbledore when he first came across the demon a hundred years ago. It took him that hundred years to gather enough strength to break the spell and to shatter the bond that Dumbledore forced upon the Phoenix; he was now free to take his human form and had never been gladder for it.

During Harry's fifth year, Fawkes helped Harry in secret to remove all the spells put upon him by Dumbledore. So between Umbridge, DA meetings, studying for the OWLs and trying to not let the younger two Weasley's know that he knew about their betrayals, Harry was a very busy wizard. Hermione helped by finding a potion that would help to identify the types of spells and potions that had been used on Harry. The list was very long and it was a tedious and long task to try and remove them all. It was during this time that Harry found out about his true heritage.

"What do you mean by 'Demon heritage'? "

"Exactly how it sounds, Dumbledore has bound your Demon powers and forced you into a glamour at birth. I can't undo the spell because it is powered by Dumbledore; the only way it will cancel out is if Dumbledore dies. You know as well as I do that his death will not be happening anytime soon." The Phoenix demon replied.

"The only other way for it to be removed is forcibly by your magic when you come of age at seventeen. The only problem with that solution is that your magic will be so strong that the battle with Dumbledore's spell may kill you; obviously the old fool didn't look into the binding spell properly. To prevent your death I will have to try and weaken the spell so that come your seventeenth birthday, and the unlocking of your full power, the backlash won't be so severe but it will cause great pain."

"Well pain is better than death so I think I'll take the second option thanks." Was the reply from the young wizard.

"Then I will attempt to weaken the spell as much as I can during the summer holidays as it will be very time consuming and I believe your absence will be more noted here then at the Dursley's."

"That's an understatement; I can't even go to the toilet without running into one of Dumbledore's spies," the statement was said with contempt.

"Well, I hope to have all the other spells removed from your person by the end of the year, if only you would stop provoking the Defense teacher then you wouldn't have so many detentions to occupy most of your spare time." Was the derisive remark from the ancient demon.

"I can't help it; there is something about that woman that rubs me the wrong way. If I didn't know any better I would thing she was a demon."

"As far as I can tell she is human, though a terrible one at that."

By the end of the year all the spells, minus the glamour and bind on Harry's demon powers, had been eradicated. Fawkes, who preferred his birth name Hikari over the name that Dumbledore forced upon him had done a rather good job considering the vast amount of spells put upon the child. It was amazing how manipulative and cold hearted one man can be towards one person he deems unworthy. Unknown to Hikari, Harry was about to make a mistake that would set forth their plans by a year and piss off one over-rated old wizard.

When Sirius Black had died and Dumbledore had finally relented to tell him the prophecy he knew that he was being lied to yet again. After he had left Dumbledore's office he had been dragged into a dark class room and had found himself face to face with his Divination Professor, the same person to bring the prophecy to life almost sixteen years ago.

Flashback

"Professor, what is it you want?" Harry asked Trelawney after she locked the door and put up a silencing spell.

"Did Professor Dumbledore tell you the prophecy?" she asked him.

"Yes,"

"What did he tell you?" Trelawney asked as she sat down.

"That isn't the full prophecy, he's edited it."

"What is the real prophecy?" Harry asked as he tried to keep a hold of his anger.

"The one with the power to vanquish the Dark Lord approaches. Born to those who thrice defied him, born as the seventh month dies. And the Dark Lord will mark him as his equal, but he will have Power the Dark Lord knows not. And either must die at the hands of the other for neither can live while the other survives. Sixteen years shall pass until a former enemy is made an ally. Putting behind their childish rivalry they will escape the manipulations of an old man. Four unlikely souls will help and together they will cause the downfall of the Dark Lord. The one with the Power to vanquish the Dark Lord will be born as the seventh month dies." Trelawney recited.

"Malfoy," Harry said after a while. "It's Malfoy, I always wondered why he never really put an effort into the fights we had, unless there were other people around."

"You're right; he has already been to see Albus. When his parents were killed by Voldemort for being spies he came to the order and asked for help but Dumbledore didn't see any use in him so he turned him away." Trelawney told him.

"I'll have to find him and speak to him about this, thank you professor for telling me the true prophecy."

End Flashback

The atrocities that Dumbledore had committed just kept piling up and he seemed to have more and more people willing to go against him and his so called cause for the light. Harry knew that the many outweighed the one but when the one became the many he could no longer over look the old man's manipulations any further. It was time to put his plans into motion a lot earlier than he planned but if he could get Draco Malfoy onto his side then he may just have a chance to pull them off. Finding and convincing the Ice Prince of Slytherin was easier said than done.

Flashback

Harry had been looking for Draco since he found out about the prophecy; the other boy sure knew how to hide. There was only one week left of school before the holidays set in, so Harry had to act fast. He found the blonde sitting by the lake on Saturday morning after two days of searching for the elusive blonde.

Harry walked over to Draco and sat down next to him, they sat there in silence for a while until Draco broke the silence.

"What do you want Potter?"

"I heard you talked to Dumbledore," Harry said to him.

"So?" was the reply from the upset boy.

"I also heard that he was an asshole and pretty much told you to get stuffed."

"What are you on about Potter?" Draco asked as he finally turned to look at the boy.

"I found out what the prophecy was about that Voldemort wanted, only the one that Dumbledore told me wasn't the right one." Harry said, still not looking at him.

"Why are you telling me all of this Potter?" Draco asked him.

"Because Draco, I believe that you will be a great help in the defeat of Voldemort." Harry told him as he finally looked at Draco.

"You – you called me Draco."

"That is your name isn't it?" Harry replied with a barely noticeable smile on his lips.

Draco just stared at him as if he had grown another head, they had been fighting for years, it was something that Draco had needed to do to keep his father's spying a secret. And now Harry was asking him for help.

"You still haven't told me what you want." Draco told him.

"After I left Dumbledore's office I came across Professor Trelawney, she's the one who made the Prophecy and she told me that what Dumbledore told me was not the whole Prophecy. Then she told me the real one."

"What was it?" Draco asked, now intrigued.

"What does it mean?"

"It means that you are the boy it's talking about. You're the one destined to help me rid this world of the foulest evil it has ever known." Harry told him.

"How can you be sure that the prophecy is referring to me?"

"Who else in this school have I got a childish rivalry with?

"Good point, okay Potter what else do you have to say?"

End Flashback

They had sat there on that rock for most of the day; Harry filled the young Malfoy in on what had been happening since their first year at school. He did leave out some things though, including the part about him being a demon, he wasn't sure he could trust Draco that much quiet yet. They made plans to leave the Wizarding world to train; if they stayed then Dumbledore would take drastic measures to pit them against each other. They had to make sure that didn't happen. With less than a week left of school they had to act quickly, they organised for Draco to meet Harry at the Leaky Cauldron on his birthday they would then leave to one of Harry's properties left to him by his parents. If all things go as planned then Dumbledore shouldn't find out about their disappearance till school started back, especially with Hermione running interference with Ron, who still thought they were his friends.

The night before Harry's sixteenth birthday found Harry sitting on his bed at the Dursley's waiting for midnight to strike. Once the clock struck twelve he would be sixteen and the emancipation papers from the goblins will have gone into effect making him a legal adult in both the muggle and wizarding world.

As Harry was waiting he noticed a dark shadow against the night sky, steadily making its way towards Privett Drive. Once it got closer he recognized it as an owl, though he didn't know who it was from. Harry opened his bedroom window and waited for said owl to enter, when it did the bird dropped a letter on Harry's lap then promptly flew back out the window.

"Who could be sending me a letter at this hour?" Harry asked himself as he opened the letter, not sensing any charms upon it.

To Our Harry,

If you are reading this letter then your mother and I have died. We are sorry to have left you but hope it was whilst protecting you. There are some things that you need to know about yourself and about your mother and I. To begin with, neither of us is human which means neither are you. Both your mother and I are Fire Demons and like you Dumbledore bound our powers to keep us in check, which is why we would have perished that night. Unfortunately the spell cannot be broken before your seventeenth birthday unless Dumbledore dies or removes the spell himself, seeing how unlikely either of those two are you will have to wait another year.

There is a house in Japan that my father bought years ago so that we could be closer to the Makai. Dumbledore doesn't know its location so he will not be able to find you there. You will find allies in the Malfoy's and with Severus Snape who should still be the current Potions Master at Hogwarts. I'm sorry that we are not around to explain all of this to you but hopefully one of the people we mentioned can help.

Know that we will always love you,

Mum and Dad.

"I guess they weren't expecting the Malfoy's to be found out and killed. I don't know what they were thinking about in suggesting Snape though."

The parts about his potions master and the binding on his parents were the only parts of the letter that shocked him. As far as he knew his father hated the potions teacher. Noticing that the clock now read 12:05, Harry grabbed his trunk after shrinking it then quietly left his room. Thankfully he made it out of the house without alerting the occupants.

Once Harry reached the street he pulled out his wand and flagged down the Knight Bus, upon entering Harry paid his fare and sat on a bed at the back. There were four passengers to get off before him so he had a bit of a wait before he arrived at his final destination for the night.

A/N: well there is the first chapter revised, hopefully you all like it. I have no idea what town in Japan Yu Yu Hakusho is based in so all that will be mentioned are the school's name. I don't even remember why I made them magical creatures before when the story is supposed to be about demons, oh well its fixed now and will continue down this route. Draco's Demon will be revealed in the next chapter and so will more information on the rest of Harry's allies.
