Diclaimer: not mine - wish it were though

On September the first the Golden trio plus Ginny found a free compartment and placed their trunks down they were soon joined by Neville and Luna who looked at Harry strangely.
"Harry when did you get tails?" Neville asked and Harry eyes widened.
"What are you talking about i don't have tails" Harry said panicking.
"I see them to" Luna said dreamily.
"That's a bad joke you to harry doesn't have any tails" Hermione said "Harry we'll see you later we have to go to the prefect car" Hermione said dragging Ron and Ginny, who was the new 5th year prefect for Griffindor with her.
Once they were out of earshot Harry turned to Luna and Neville.
"How the hell can you see my tails?" "You mean you do have them?" Neville gasped, "I thought i was hallucinating"
"When did you become Kitsune?" Luna asked.
"Since the day i was born" Harry laughed.
"Are you really Harry Potter or have you done something to him?" Neville asked pointing his wand at the kitsune.
"I'm Harry potter yet i am not" Harry answered confusing Neville though Luna looked as she always did "7 thousand years ago i met a seer who asked me to be reborn here and help with Voldemort so 17 years ago i set up the reincarnation and went through with it having chosen Lily and James however things went wrong and the burst of power from me entering the featus got the attention of 3 people, Voldemort, Dumbledore and a seer by the name of Sybil Trelawny"
"Not batty Trelawny"
"The very same she spoke a prophecy that was not supposed to centre on me but because of the blast of power Voldemort decided to come after me and i became the saviour of the prophecy instead of the protector of the saviour when the killing curse was cast my memories and power was locked away and now I'm slowly regaining my power the memories came back on my birthday"
"What is your true name?" "Haru of the nine tails kitsune clan" As harry said that his human form melted away leaving his human Fox form his tails were mainly silver with red streaks and blue tips, his ears were pure silver tipped in blue his hair was also nicely brushed with the colours shining.
"Your beautiful" Luna commented and Haru smiled. "I thought Demons hated humans why are you helping? why haven't you left"
"Kitsune unlike most demons are literally bound to their promises, as Haru i promised the seer 7 thousand years ago that i would help the saviour to defeat Voldemort, as Harry i promised to kill Voldemort so I'm bound by both promises and even as Harry that part of me was still there i never broke a promise never" Harry said as he melted back into his dark haired form. "So how can we still see your hybrid form?" Neville asked.
"You two have an ability called true sight it's extremely rare, i think you have it because i was meant to be your guide but no clue why you have it Luna"
"Guide"
"The prophecy was originally supposed to be about you not me but my power burst got everyone's attention" Harry explained "i was supposed to guide you in training teach you to master your elemental abilities which I'm still going to do"
"I hope your not mad about this but I'm glad it was you and not me" Neville told him.
"Seeing the unseen runs in the Lovegood family" Luna told them.
"So what exactly does it mean and what about this elemental stuff you mentioned"
"I said Elemental because you have a strong ability to utilise the Earth Elements, the mud the rocks the trees and plants, will obey you and will be very willing to help you for true sight in it's rawest form it's just seeing things as they truly are physically, you'll never be fooled by glamours, you'll see the person or things true form as a see through overlay like with my tails, they aren't there but because my true form is a kitsune the fox boy is as close to my true form as you can get when I'm standing you'll probably see my full fox form around my legs, with training the true sight can be used to see falsehoods in peoples speech, you'll know when your being lied to but not what the truth is, the next step is knowing the truths when your being told lies and seeing the truth if anyone tells you something, That level is the top say if someone told you Professor Lupin wasn't a werewolf you would get a flash of an image of the truth of Remus transforming, or if someone said that Lucius Malfoy had never killed anyone you would get a flash of the people he killed"
"Or if someone said Dumbledore didn't kill grindlewald we'd get a flash of what happened?" Luna put in.
"Exactly" Harry nodded, "luckily at that level the true seer's can turn the power off or down because of this those with true sight are sometimes called seers because the see flashes of the truth it is not rare for a person with true sight to also be a seer."

After the feast Harry snook away carrying with him all the details of Kyuubi Haru and Harry Potters account details and made a stop at the kitchens to get a hamper of meat before going down into the chamber of secrets once down the slide Harry immediately took his fox-human from and wrinkled his nose at the smell,.Using his wand he cast multiple cleaning spells and carried on walking towards the main chamber. Opening the door he smirked from the smell of rotting basilisk with a few more spells the smells was gone and the snake was in large jars separated into different pieces such as scales, teeth, bones, and innards each in separate jars. The fox then set about exploring and found a hidden library that amusingly enough didn't have the scent of Voldemort that the other rooms carried there was also a small bedroom, bathroom, kitchen and a seating area all were covered in dust and it took Haru quiet a few spells to clean it all once it was clean Haru set out his box on the library table and bit his thumb his fang broke the skin and blood welled up which Haru pressed against the Gringotts seal which changed into a nine tailed red fox and opened.
12 vaults all belonging to Kyuubi Haru the first vault was money, the seconds jewels and metals, the third was books and scrolls, the fourth contained weapons and armour, the fifth to tenth held his treasure, anything he had stolen from other demons. The eleventh vault held maps of his various hidden caches in various worlds and his own records of events plus contracts and deeds to various places, the twelfth gifts that had been given to him that he wanted to keep safe. All his Vaults could be accessed remotely by the use of a charmed box which was sat in his twelfth vault which he would have to go back and collect. After making sure nothing had happened to his account in the last 17 years Haru stretched and went to look at the different books that Slytherin had left hidden in his private library luckily demons need less sleep than Humans so Haru spent until 3 going through the books and releasing some of the blocks.
He woke up with Ron shaking him shouting about breakfast Harry shook his head and headed towards the shower telling Ron to go down.
"Nah I'll wait mate so where were you late night anyway? you dissappeared straight after the feast"
"Went down to the chamber to release some of the blocks" Harry answered.

"Defence first" Hermione said as Harry and Ron sat and she handed them their schedule. "NEWT Defence," Harry nodded looking at the sheet, "for two hours then single charms lunch and then double transfig. and a single ancient studies"
"Ancient studies why are you taking that?" Ron asked his mouth full of toast as Harry bit into a sausage and shrugged.
"I thought it sounded interesting"
"What else are you taking? i forgot to ask before" Hermione said.
"Healing, ancient studies, duelling, Languages newt defence charms transfiguration and COMC"
"That's a lot of work" Ron commented. "Yeah but I'm interested in ancient history as long as binns isn't teaching it, and i love languages, healing, and duelling will be good for face voldie" Harry explained"well we should be getting to defence" Hermione said dragging Ron away from his food standing at the front of the classroom was a tall brown haired man with bright blue eyes wearing pink robes Harry stopped to stare for a second not believing a wizard would actually wear robe that pinks especially a male wizard after all pink is not a male colour.
"Welcome to Newt Defence I'm Robert macmillion you can call me Professor mac i want you each to stand up and tell me your name, house and any hobbies lets start with you" He said pointing to Hermione who was sat on the end of the front row.
"I'm Hermione Granger, Griffindor, i like reading and learning new things and my favourite class is transfiguration"
"Ron Weasley," Ron said standing, "Griffindor my hobbies are chess and quidditch and my favourite class is lunch" that gained him a grin from the Griffindors and even some from other houses.
"Harry Potter, Griffindor I like quidditch, learning languages and my favourite class is defence against the dark arts"
"Languages how many do you know"
"Three, English, parsel and Japanese" Harry answered as Neville who was sat next to him stood.
"Neville longbottom Griffindor i like nature and sitting outside under the tree's and my favourite class is herbology" after they had been around the class the professor spoke again.
"Well for the next week were going to be doing a rapid review of everything your supposed to have learnt over the past 5 years"
The rest of the day went by slowly and was boring just reviewing the past years "welcome to ancient studies I'm professor mae ancient studies covers everything from the study of civilisations to old races and places"
"Races?" a Ravenclaw asked.
"Yes we'll be learning about vampire history, the first born Elves and demons"
"Demons? they don't exist"
"About 7 thousand years ago there were the demon wars a war between wizards and demons the wizards killed thousands of demons and the demons killed triple that number of humans in retaliation it got worse after wizards started to kill demon children, demons are extremely protective of their young the wizards biggest mistake was to kill the kitsune demon lord Haru's only son, Haru went insane and killed as many wizards he could find before a young woman stepped in front of him, she had healed the fox before and he instinctively knew who she was and didn't want to hurt her with her persuasion Haru took the demons through a portal and sealed the way into this world however Haru's last words before he left were that he would keep his promise to the young girl but he could never forgive the wizarding world for starting the demon war nor for killing his only son"
"Wow what a story"
"There a copy of the story from 3 perspectives in the library for extra credit you can write an essay on your thought on the story, now later in the year we'll go more in depth in the demon wars and the demon hierarchy, we'll also be looking at Merlin's time period where ironically enough the Demon Kitsune lord Haru appears for the first time in our history, Atlantis and what led up to it sinking, as well as studying the ancient druids."

"Wow the story about Haru is really interesting" Hermione babbled to Ron, Harry Neville and Ginny who were all say together in the Griffindor common room "All through the demon war Haru stayed out of it even though he was extremely powerful he just stayed and protected kids there are stories of him taking Human form and battling other demons to protect Human children and at the time his son was only 5 years old but was a good fighter as well you had to be in the demon world otherwise they would be killed, anyway one night Haru had heard about an attack on a defenceless village so he went to help he left his son with some human children being protected by his mate but when he got back to his den he found all of them dead and the scent covering them was of a band of humans. Haru went insane with grief and started to attack the male fighters he still left the women and children alone unless the women attacked him and even then he would only knock them unconscious the men that came up against him soon found out why Haru was know at the strongest kitsune to live, no one could stand against him and his parents fought with him. Until Cordette who was a seer and a master healer in the war she had given Haru sanctuary several times and looked after children that he rescued. Cordette stood in front of him and wouldn't move no matter how many times he barked at her to move, She pleaded with him to let the anger go and to not let any more children grow up without their father, Haru asked why should he care they did not care when they killed his son and mate and that he had protected their children. I can't help but feel for Haru i mean for years he protected their children and they go and turn on him by killing his son"
"He was a demon Hermione" Ron spat "Why should you care about that? He's probably long since dead"
"Actually he's probably still alive" Neville commented "he was only 6 thousand when he fought in the Demon wars and Demons can live up to a few million years maybe longer"
"And he did promise Cordette something and Kitsune, according the the books i read, are bound to their promises even if they don't want to keep them"
"Hermione he killed hundreds of wizards" Ron complained.
"Only After the Wizards and Warriors killed his son, mate and some human children that were under his protection" The Bushy haired witch argued.
"Who cares about some Fox kit? There just demons there just dumb beasts, and he was probably going to brainwash the children to think he had nice so they would attack other humans for him" Harry couldn't stop himself from growling at that which got him every bodies attention "I cant believe you would say that" Harry shook his head "the humans your so busy defending started that war, the demons just fought back and had to hold back on killing humans because of the Riekai laws until human started to target their young then the demons didn't care that the penalty for kill a human was 200 years in prison they just attacked Haru hated it but the only thing he could do was protect the children and he did so his parents tried to get him to fight with them but Haru refused to be part of it he just wanted to keep as many children safe as he could until his own child was killed then he sent up a howl that sent shivers down demons and Human backs alike" With that said Harry stood and left with Neville chasing him.
"You still remember it?" He asked quietly and Harry nodded "Yes coming back to the den to find them dead was the worst moment of my life they were everything to me, nothing i can say could describe the feeling of seeing your first kit born, times were hard but in the maikai it was always hard but this time there was no sanctuary for my kit and mate i couldn't take them with me when i hopped to another dimension all i could do was try to keep them safe and i failed, if it had been up to me i never would have come here i would have let these Wizards Rot" Harry spat "Ron is a perfect example of wizard predjudice he just spouts what he's been told, Dumb beast my tails the older we are the more we know and I'm a hell of a lot older than he is"
"Calm down you don't want to go fox and blow this whole castle sky high" Neville cautioned and Harry nodded as they continued walking.
