Not mine

The next morning the great hall was buzzing with the news from the daily prophet. "Morning guys what's happened?" Harry asked sitting down with Hermione, Ron and Neville.
"There was a raid last night made by a demon on knockturn alley" Hermione said passing the paper over which showed Haru's fox form lying with 5 children still sat on his back all injured and Percy refusing to move as he watched over the kids "the Fox is Kyuubi Haru who hasn't been seen in the wizarding world for seven thousand years he's the same Haru as from the Demon War and Percy was one of the victims, according to the newspaper it was a bloodbath inside the inn"
"The most controversy is being caused by four of the death eaters" Neville added. "Bellatrix Lestrange looked like she'd been boiled from the inside, but the three that really caused it were Umbridge and Minister Fudge there was a note written in their blood which said they'd been death eaters for years and that humans hadn't noticed"
"Harry the other death eater was Peter" Ron said and Harry head shot up and was painted with a look of shock.
"What"
"Yeah he was the only one alive not that that says much he was pinned to the wall the paper says he's insane just keeps repeating 'traitor traitor' he's also blind, his trial is going to be in a few days and madame bones has taken over as the interim minister until a new one can be selected"
"Lucius Malfoy was also found dead" Harry frowned he hadn't remembered killing the ferrets father. "He was decapitated in the main pub" Hermione explained "Most of the bodies in the first room were either sliced apart or were just killed by having their throats sliced"
"Hermione were eating breakfast." Seamus complained pushing his plate away.
"How did your brother end up there Ron?" Harry asked.
"He stood up to the minister," Ron said proudly. "he found some documents and confronted fudge unfortunately he was taken prisoner and placed in a cell and tortured for daring to go against fudge he'd been there 3 months, Fred and George sent me a letter earlier and said mum's been fussing over him in St Mungos that even the Healers are finding it amusing."

Two months after the knockturn alley incident as it was being referred to Haru again left Hogwarts this time to visit the Azkaban prison he started in the lowest levels while summoning some small demon goblins that were under his command and sent them to map the whole prison and create a map. Taking his Fox form Haru started to explore the lowest level himself the tiny demons soon came back bringing with them the location of prisoners and artefacts Haru wasted no time working his way through the prison killing any Death eaters he came across as he headed up to the nearest row of cells where he found 20 people hiding in the back of their cells using his fox fire Haru Quickly melted the bars.
"My Name is Haru I'm here to rescue you" The kitsune said and the most able-bodied prisoners came forward out of their cells over coming the fear of Haru his presence was comforting and while they came out Haru ducked into the cells that with the most injured and started healing them of their worst wounds before bringing them out and placing them with the ones that could stand on their own.
"I'm going to create a portal to st. Mungo's Tell the healers to be ready to receive as many Wounded prisoners as i can manage to find in the next 5 hours" Haru commanded bringing the last injured man out and opened the portal and started to levitate the wounded through it not going through himself when the last was through he closed it and headed for the next lot of cells 5 hours later 400 prisoners had been moved 2 library's and 7 rooms full of dark artefacts had been emptied Haru smirked as he left knowing he had just caused Voldemort a lot of problems.

After several months of raids on Azkaban and knockturn alley Voldemort was getting more and more agitated no matter how many wards there were Haru went straight through them by the end of the year Haru had decided he would stop playing and kill Voldemort himself so he could leave this world he had completed Neville and Luna's education in Elemental abilities and had copied several books to help any children they had to harness their own power, and how to focus and refined their True Sight Voldemort blamed the disappearances of his victims and other books and artefacts on Dumbledore and Harry Potter even if neither of them could have done it or passed through the number of wards on Azkaban and so with an army of dark creatures he travelled to Hogwarts not even telling his most faithfully what he was doing and not taking any of them with him.
"Professor" Hagrid shouted coming into the great hall at breakfast "There are dark creatures appearing at the edge of Hogwarts wards they can't get through but there trying." Harry who had been coming down to the great all with Neville stopped and Harry melted into full fox form "Go to the room of requirements that will keep you safe and I'll need you to hold my wards"
"Your wards"
"Yes I'll be to busy to hold them you'll just need to ground them with your earth element, now go" As Neville ran off Haru stepped into the great hall as everyone was shouting about what they should do.
"You will calm down and leave those creatures to me" Haru's growling voice rolled around the hall gaining the attention of the whole student body.
"Who are you"
"You don't recognise me I'm hurt i am Youko Kyuubi Haru" Haru said sitting proudly. "Why are you helping us"
"I made a promise along time ago i would destroy the Dark Lord Voldemort and even more so when he tried to summon the Demon Foxes to help him"
"Your the ones who's been doing the raids" Sinistra said and Haru bowed his head in acknowledgement "My wards will go up as soon as i make my way outside you will be blocked inside the castle itself i don't think i will fail but still the wards will drop if i die or Harry and Neville both falter while holding them but the latter should not happen they have been practising for this for quiet a while, Luna go join them they're in the room of requirement join them three will hold them better than two" Luna nodded and raced out but not before placing a kiss on his muzzle and a scratch behind his ear. Standing Haru made his way out side building the Demonic wards to keep everything out of Hogwarts castle.
Haru stood ready as he watched the creatures break through the wards the first wave were dermentors and vampires which Haru sent waves of blue Fox fire at both the vampires and the dementors turned to dust at that level of heat Haru started to run towards the next wave which was nundu's and snakes and Haru took great delight while ripping them to pieces albeit with a few wounds that sealed and healed very quickly blood dripped from his mouth as he looked at what he would be facing next Werewolves which a snort Haru sent a wave of pure air pressure slicing the werewolves into pieces Haru looked at the edges of the wards then and saw hundreds more dark creatures. Snakes, Dementors, nundu's, acromantulas, and other nasty creatures most however cringed when they saw the silver Kitsune stood there blood dripping off him and their comrades in pieces littered around him finally Voldemort himself appeared and Haru Snarled.
"Tom Riddle we meet at last" Haru said swinging a tail and making a tsunami wash away many of the dark lords army a blast of Fox fire got rid of the rest so only two were stood on the battlefield.
"You are strong to have destroyed my army but i am stronger still submit to me and i will not harm you lord Kitsune"
"I am very old and very powerful i do not need or want anything a pitiful Human could offer me" Haru spat and Voldemorts face screwed up in rage before calming.
"I can give you power, servants"
"All of which i have," Haru growled "do not play games with me i am far older than you could ever comprehend"
"We will see" the fake lord said and shot off the killing curse which just washed over him "You never paid much attention to your history did you? That spell nor any other of your human spells will work on one such as me" Haru moved fast and pounced on Voldemort using his front claws and fangs to rip him apart before using an old demon spell to destroy his soul.
"The promise i made is complete and i am free" Haru muttered making his way back to the castle tiredly he navigated his way to the room of Requirements and went straight in to flop to his belly beside the two magic users and looked up tiredly "You can drop the wards voldies dead" Neville and Luna nodded and relaxed their hold on the Kitsunes wards causing them to drop.
"Haru you need to change back" Luna said cast a spell to rid him of he blood covering his form Haru nodded and soon Harry was laid there instead.
"What will we tell them when your so exhausted and me and Luna aren't that bad"
"I was holding most of the wards you two where balancing me" Harry said as he fell asleep exhausted. Neville sent a few more spells to clean Harry up and finished just as the door banged open from Dumbledore and the other heads of houses.
"Voldemort is dead" Neville said and followed Harry into unconsciousness leaving Luna to deal with everyone.

In the middle of the next night Haru awoke still faking sleep pushing his senses outhe knew that everyone was asleep and so he sat up in his bed and stretched, He knew if he stayed around nothing would change, as Haru he would be hated and as Harry he would either stay as he was, adorded for being the boy who lived, or critisised for not being the one to bring the Dark Lord down with that in mine Harry stood and shifted into Haru he created a Fox fire clone of his Harry self and cast a coplex illusion over it so it had seemed like the Boy-who-Lived had died from magical exaustion and the breaking of the connection with Voldemort. When Madame Pomfrey checked on her patient the next morning she let out a scream when she found Harry had died in his sleep. The train ride back to London was done in Silence and the Wizarding world moarned.
Neville and Luna, who was staying with neville for the week, headed for Nevilles home with his grandmother, all three of them got a shock when they got there and saw, lying out in plian view basking in the sun, a Nine tailed silver fox stretched out in the sun.
"Haru" Luna and Neville shouted forgetting dignety, dropped their luggage and ran towards the fox who sat up and shifted into a young teenager who hugged them.
"Hi" "Why didn't you tell us it was a trick i thougt you were dead" Neville shouted.
"I know and i'm sorry, but i had to, i'm leaving tomorrow and that was the last loose end"
"Loose end?" Neville asked inceduously but Luna seemed to understand.

Before the end of the school year Harry had sent a letter to the Dursleys telling them he wouldn't be back and had merged the potter account fully with Kyuubi Haru's account.
"I guess this is goodbye" Neville said as they stood in a field near Neville's home Haru having spent the night there.
"I want to go home" Haru said "find my brothers." "Will you visit sometimes?" Luna asked.
"I promise" Haru opened his hand to show two pendants both with a nine tailed fox sat proudly done in bright silver "these pendant will allow you to contact me, i want you to summon me at any important event like your birthday, wedding when you find out your having children i swore to protect the Longbottoms and Lovegood. The Weasleys all have pendants waiting for them at the burrow with a note telling them to call my name if they need me, Hermione's is there as well. Ron and mione don't know i was Harry and i want to keep it that way as far as they know Harry Potter never woke up from holding the wards"
"We understand" Luna said taking the necklaces and passing one to Neville.
"Look after each other" Haru said and walked through the newly made portal.

AN the fight scene will probably be redone sometime in the future
