To those following me, I know I have other fanfics to write but I just had the urge to write something different and see where it'll lead me. But don't worry, I'm still continuing with my other fanfics.

As for this, Harry disappeared at the end of his 1st year and has appeared during his 4th year while the two schools have arrived and the first trial has already ended; so his name hasn't been drawn from the Goblet.

For Tokyo Ghoul, this fanfic starts near the end of season 2, so instead of Kaneki going to the CCG investigators, he's going to Hogwarts to live a fresh life away from Ghouls. (But obviously shit will happen)

I haven't read the manga, so it'll be going off of the anime so I'll just say now that from what I can go off of Kaneki has control over his centipede kagune, but will also have bouts of insane moments. Also, I know Kaneki was in college but let's just pretend that it's high school.

Also, it'll be explained why Harry/Kaneki was in Japan in the first place and I'm pretty sure you all have an idea as to how he got there in the first place. Also I'll be referring to Harry as Kaneki. Aaaaannnddd there may be a tiny bit of Dumbledore and Rin bashing. Idk yet. It may not happen.

"Let's go home." Were the last words he heard from his best friend as his hand slipped from his face, devoid of life as he's left alone for good this time. Kaneki felt tears run down his cheeks but he didn't care, nor did he care about the uncomfortable position he was in, nor did he care about a CCG investigators finding him or that there was a battle raging on a few streets down; all Kaneki cared about was the hollow feeling in his chest….And after he learns that Hide, his one true best friend that helped him through these tough times, accepted him still and he never got to tell him the truth. That Kaneki isn't his real name, that he wasn't normal to begin with… that he's a wizard. He never got to tell Hide about his first year at Hogwarts, about learning magic and the majestic castle or his adventures from when he was still an innocent and naïve kid. He didn't get to tell him about Ron and his brothers or Hermione or the twit Malfoy.

His friends…

Kaneki's eyes widened slightly in realisation. How were his friends in Britain doing? Better than his situation he hoped. Ever since he got stranded in Japan and left for dead by his Aunt and Uncle he remembered trying to find a way to contact them, but due to the fact that he had no money and couldn't at the time speak a lick of Japanese he had no way of contact; especially seeing as his Uncle wouldn't let him bring anything, not even Hedwig, but he did manage to sneak his wand along with him. Once he managed to find the police, they attempted to get a hold of his relatives but he didn't know anything other than their names. But after some questions and soon discovering his malnutrition he was placed in a foster home, where he later got adopted into a loving home with a woman he could call a mother. After finding a home, he was that engrossed in learning Japanese and the culture of Japan that it seems that he'd forgotten all about his missing status at Hogwarts.

Of course, him becoming a Half Ghoul didn't help the situation either, or becoming an SS ranked Ghoul. A thought crosses Kaneki's mind. Ghouls in Britain were deemed as dim-witted and docile, is it possible for him to go back? To live a normal life again? It's possible now that he thinks about it; he still has his wand in his old apartment too. Now that he thought about it, he vividly remembers a year or two after being stranded in Japan learning how to do Apparition. He'd told his adoptive mother about him being a wizard and how he got to Japan in the first place. Kaneki smiled, he remembered that day well, how kind and understanding she was and how she later on helped him find anything that could potentially help him get home. By the time he found something on Apparition he was turned into a Ghoul a few weeks later and forced into this hectic life style of cat and mouse.

"There's nothing left for me anyway." He thought to himself sadly, still letting the tears flow freely down his cheeks as he could slowly feel Hide's body go cold. Sure, he had Touka-chan, Hinami-chan, the manager and the rest of the staff at Anteiku but it wouldn't be the same. He already got Hide killed without having to be in his presence and Anteiku has been attacked more than once now due to him; he just can't handle putting everyone in danger again. Isn't that why he left in the first place?

With his mind made up, Kaneki got up, gently laying Hide's head on the floor before finding a white sheet and covering his body before leaving the store. As he walks out, Kaneki places his mask over his face, covering his identity as he sets out in a run, jumping from building to building; using his Kagune from time to time as he hastily makes his way to his old apartment, praying that his belongings may still be there. As he reaches the familiar looking building, he smashes through the window; not caring for whoever owned the building.

His belongings, to his dismay, weren't there, but in their place was someone else's. Which left only Hide's place. Knowing Hide, he'd be storying his friends belongings in the hopes that Kaneki will come back. A small, sad smile graced his lips at the kind thought of Hide but the smile immediately vanished as he set out in a run again. He didn't have much time. Whilst there aren't any people in the area due to the battle, that battle will be ending soon, and with that meant more CCG in the area.

After running for another 10 or so minutes he comes across the familiar sight of his friend's apartment. Kaneki's heart clenched at the sight, knowing that he'd have to more than likely upheave the place if he wanted to be quick. He smashed through the window like he did previously and began his search for his belongings; not having to look for long as he spots a couple of large boxes with "Kaneki's stuff" written all over them. Kaneki wasted no time ripping open the boxes and searching through their contents. If he remembers correctly, he hid his wand in an old bible he found, cutting the pages to create a hidden compartment for his wand. As the time ticked by he began to worry that Hide either didn't take much notice of the bible or through it out, believing to have no importance to his friend.

Just as he's about to give up a smile stretches upon his face as the familiar and happy site of the old and torn black bible comes into view. Kaneki quickly snatches it up and out of the box and quickly flicks through the pages. In no time, the familiar and comfortable weight of his wand is in his hands once again after years of separation. Kaneki looks at the wand, after years of being separated from magic, the very thought of magic seems foreign to him; feeling like a first year again when a heat of embarrassment rushed through him when he got his first wand and had to swish it at random like an idiot.

Kaneki stood up, putting the memories at the very back of his mind and concentrated. From what he could remember about Apparition, you need a clear idea of your destination and think of being there. Kaneki stood still, trying to the best of his ability to remember the front gate of Hogwarts, the structure and design of the gate, the fascinating yet eerie environment and the brilliant and imposing view of Hogwarts behind the gates. He concentrated, pushing any doubt that appeared to the back of his mind as he at last felt an odd tug as he watched Hide's apartment disappear in a swirl of colours.

Kaneki thought he'd be sick, and was about to throw up when he connected with the dirt road at the front gate of Hogwarts. Hard. Kaneki groaned, still weak from his injuries he sustained from his fight earlier. Kaneki slowly got up, covering his eyes as they hit sunlight, completely forgetting the different time zones.

He was here, at the front of Hogwarts gates, and judging by the sun he'd say everyone should be in the Great Hall having breakfast. At the thought of human food his stomach churns, not having thought through what he'd do about eating once back at Hogwarts. Oh well, he'll go deal with it once the situation occurs. But first, he should take off his mask; least he wants is to be hexed for his sudden intrusion and Kaneki doubt wearing a mask will help his case, and stuffed the last in one of the pockets in his pants. With practices eased Kaneki jumped over the imposing gates of Hogwarts, the wards recognising him as a student after all this time, and slowly made his way towards Hogwarts, towards his past life… towards his friends.

Along his journey, Kaneki thought over what to say once he gets there. His appearance has drastically changed due to the torture and along with his personality. He also doubted his mental state is healthy either. He could just reveal his scar to them, but they'd most likely continue to suspect him, he just hopes that Dumbledore will hear him out because Kaneki seriously doubts he has the patience anymore to deal with the Headmasters cryptic talk.

As Kaneki stands outside of the Great Hall he can hear the lively chatter of the residents inside. Kaneki, just as a precaution, placed his eyepatch over his Ghoul eye. No need to scare the students any more than necessary. With the eyepatch on and a deep breath, Kaneki pushed open the giant doors to the Great Hall with ease and noticed almost instantly how the chatter a few seconds ago vanishes in the blink of an eye at his sudden appearance, a few gaps could be heard from both male and female students alike and Kaneki wonders what's wrong . In an instant the Professors at the staff table stand up and made their way closer, wands trained on him. Amongst the staff table, Kaneki noticed two adults that looked so out of place that they must've been foreigners. One was a very tall lady wearing a navy blue dress with furs whilst the other was large male, although not as large as Hagrid, wearing a thick red coat. Kaneki also noticed students amongst the Slytherin and Ravenclaw table with similar uniforms. Was Hogwarts hosting an event? Dumbledore, with his wand also out, make his way slowly in front of the other staff and approached him.

"How'd you get inside of Hogwarts, young man?" Demanded Dumbledore, the twinkle in his eyes long gone and in its place was a seriousness Kaneki had never seen before.

Kaneki though, smiled at the Professors. Dumbledore hadn't changed much from what he could remember, Snape looked the same but with longer hair and McGonagall looked as strict as ever. Flitwick looked the same as well as Madam Pomfrey and Hagrid. But there was someone new amongst them. A battle scarred man with a mechanical eye and a wooden leg, but something didn't smell right about him; he didn't smell entirely human; like two humans merged into one.

"I shall repeat. How did you get through the wards?" Asked Dumbledore, raising his voice as he gains Kaneki's attention again. Kaneki smiles, completely at ease with his current predicament.

"I expected a warmer welcome. But then again your reactions are understandable. I imagine I look completely different to when we last saw each other, Headmaster." Kaneki replied smoothly, gaining looks of confusion from both the Professors and students alike. It took a while for Kaneki to respond, having been a long time since he last spoke fluent English.

"I apologise, but it appears my old age is finally catching up to me, would you mind introducing yourself? It seems I do not recall ever meeting you." Came Dumbledore's reply, and Kaneki began to wonder how they will all fare at the news.

"My name is Kaneki Ken. But you all know me as Harry Potter."

The Hall was deathly silent as the Professors and students gaped at Kaneki like he'd grown a second head.

"Sorry if we don't take your word, but Harry Potter went missing four years ago." Sneered Snape, raising his wand higher to meet Kaneki's eyes. "Do you have any evidence to support your claim?"

Slowly, as to not alarm the Professors, Kaneki raises his white bangs to show the lightning bolt like scar on his forehead; earning a few gasps at the familiar sight. At the sight of the scar, McGonagall lowered her wand, mouth agape.

"Potter? Is that really you?" She whispered, but her voice stood out amongst the silence of the great Hall.

"Harry!?" Shouted a feminine, yet familiar voice to his right. Kaneki looked over to see a very familiar sight of bushy brown hair and red hair. Hermione and Ron.

"Hermione, Ron, it's good to see you two once again." Hermione gasped slightly, covering her mouth with her hands as tears begin to form in her eyes whilst Ron stared at his first every friend, dumbfounded at the drastic change in both appearance and personality.

"If you are who you claim to be, then mind explain to us why you're covered in blood?" Asked the man with the mechanical eye.

Kaneki blinked owlishly and looked down at himself, only to find that indeed, he is covered in blood. Kaneki mentally smacked himself for forgetting about his injuries, now that they were mostly healed and the pain now only a dull ache it was easy for him to forget.

At once chatter filled the Hall louder than before as talk of Harry appearing in the Great Hall covered in blood bombarded his enhanced hearing.

"Silence!" Bellowed Dumbledore as the entire Great Hall falls silent once again.

"I think it'd be best explained in privacy, Headmaster." Said Kaneki softly.

Dumbledore stared down at Kaneki for a moment before nodding. "Of course, I understand. I hope you don't mind though if Professors McGonagall and Snape join us?"

In all honesty Kaneki didn't really care, it's not like he's going to tell them the truth. Even if they did attack him it's not like their spells will have much effect on him and Dumbledore would not be the first he's killed.

"No, I don't mind."

"Excellent. Please follow me."

"Wait!" Kaneki turns around to see Hermione and Ron still standing, now only a couple of metres behind him. "Please let us come along." Pleaded a tearful Hermione.

"I'm sorry, Miss Granger. But I'm afr-"

"Let them come." Intervened Kaneki.

Dumbledore, looking startled at the sudden cut-in, stared at Kaneki before replying.

"Are you sure?"

"Yes. I'll be telling them either way, and it's best they hear in privacy than somewhere someone can easily eavesdrop." Stated Kaneki with an air of boredom.

"Fair point. Come along Miss Granger, Mr Weasley. Professor Moody, would you mind watching over the students whilst we're gone?"

"Of course not." Replied the scar ridden man which Kaneki can now identify as Moody.

"If you'll follow me." Kaneki followed Dumbledore as they exited the Great Hall, which then filled with chatter once again. The walk was dull and boring to Kaneki, but he didn't mind. Having been active during the night time Kaneki got use to the quietness known as night.

"Harry?" Asked a hesitant voice behind him. Kaneki lazily looked behind him to find that it was Ron who spoke. Kaneki didn't respond, but held eye contact.

Ron, sensing this was his que to speak, spoke hesitantly and quietly; aware that the Professors were listening as well.

"What happened to you, mate? You disappear for 4 years and now you suddenly return with white hair, blood stained clothes and a different feel about you. Where were you all this time? What happened? And is…that your blood?" Now the Professors had their full attention on him at the mention of the blood on his clothes.

Kaneki hummed to himself, before cracking his index finger with his thumb, causing a loud crack and making both his friends and the Professors flinch slightly at the harsh sound.

"I was in Tokyo."

"Tokyo? As in Japan?" Questioned Hermione.

"Yes."

"What were you doing all the way in Japan?" Asked Ron.

Kaneki continued his walk, never slowing down or looking back behind him. "My Uncle won a free holiday from work to Tokyo. Of course, I had to come along as well. You see, contrary to popular belief, my relatives despised me. They saw me as a freak due to being able to use magic. So seeing this as the perfect opportunity, took me to Tokyo with them and abandoned me there, with nothing but the clothes on my back and my wand." He said casually, seemingly not bothered by the fact that he was abandoned.

Hermione gasped whilst the Professors and Ron paled. Before anyone could say anything else, Dumbledore announced their arrival.

"Lolliepops." The Gargoyle jumped off to the side, revealing the same old set of spiral stairs that Kaneki remembers. Once inside, Dumbledore took a seat at his desk whilst McGonagall took a seat, motioning for her three students to do the same. Kaneki continued to stand though, along with Snape, too used to always being on the go to sit down and relax.

Dumbledore, not seeming hindered by Snape or Kaneki standing, began to speak.

"So, before we start, what would you like to be called by? From our earlier conversation, you referred to yourself as Kaneki Ken, am I correct?"

In all honesty Kaneki didn't know what to choose. Harry was the name associated with his old life as a student at Hogwarts. The naïve and wonder-like child that was untouched by evil. Kaneki was the name given to him by his foster mother as a means to a new start. It was also the name associated with Anteiku and Ghouls.

But, in the end, whilst his name was associated with the pain and suffering he's endured, it also proves that he cannot simply go back to living a normal life. Plus, he's grown quite attached to his new name.

"Kaneki is fine."

"As you wish. Now then Kaneki, mind starting from the beginning?" Kaneki nodded his head.

"As I mentioned before, my relatives abandoned me in Tokyo during their holiday. I had nothing of use and couldn't speak Japanese. After a while, I managed to find a police station, where I reported my situation. They couldn't find my relatives, and after some questioning, they deemed my relatives unfit to look after me and put me in a foster home. There, I grew up with a new name and a new start, my foster mother teaching me Japanese and about their culture. But I wanted to return home and she understood, but she couldn't take me back, for any form of traveling to or from Japan is forbidden. So I told her that I'm a wizard. She believed me and accepted me, even helped me find books on traveling magically. But as the years passed on my foster mother died from over working."

Hermione and Professor McGonagall both gasped quietly at this, Hermione looking as if on the verge of crying again.

"You said that travelling outside of Japan is forbidden. Why is that?" Asked Snape. Kaneki stilled slightly. Should he tell the truth? Or perhaps just half lie to them?

"In Japan, there's a high crime rate. Gangs related deaths were a common thing in Japan. Tokyo is even separated in different sections known as Wards. I lived in the 20th Ward, which is known to be the safest one. Due to the high crime rate, the Japanese government has forbidden travel in and out of Japan to stop any criminals from leaving or coming in."

"How horrible." Whispered Hermione. Dumbledore lost the twinkle in his eyes and Ron looked even paler. Even Snape looked a bit paler than usual.

"Care to explain the blood then? Were you apart of these gangs?" Questioned Snape in his usual drawl, almost as a way to cover himself up. Either that or the bastard wants to try and find a weakness.

"No. A couple of hours before arriving here, there was a fight between the CCG, which are our police that control the gangs, and two gangs. The area was evacuated but I didn't hear the announcement and got caught in between one of the fights." Kaneki lied smoothly without missing a beat. After all, it is true, minus the ghoul part.

"That still doesn't explain the blood. Even if you did get caught between a fight you don't appear to be injured. I wonder, did our precious savior kill someone?" Sneered Snape, earning him a disapproving look from Dumbledore and McGonagall and a death glare from Hermione and Ron.

"You don't know the half of it" Kaneki smiled to himself. He wonders what their reaction would be if he said yes. But unfortunately, as amusing as it may seem, he couldn't risk it.

Instead, Kaneki held his index finger over his mouth in a shushing gesture with a bored expression lacking emotion, and purposely leaked some killing intent.

"Shut up and listen. I'm talking." The reaction was instantaneous. Snape froze and paled, mouth agape in shock along with McGonagall, Ron and Hermione tensed at the sudden killer intent Kaneki emitted and Dumbledore sat up straighter, a seriousness held in his eyes at the sudden change in atmosphere.

"If you must know, sensei, I wasn't the only one caught in the cross fire. My friend, Hide was as well. This isn't my blood you see, but his, as I slowly watched him die in my arms unable to do anything to help him."

Snape looked ashamed, although he hide it well, while tears flowed freely from Hermione. McGonagall looked ready to cry as well. Hermione looked ready to run up and hug Kaneki, but judging by the look in her eyes the only thing stopping her is the killer intent Kaneki emitted before.

"Please, continue." Spoke Dumbledore softly.

"After that I remembered the instructions I found for Apparition. So, I decided to see if I could make it home. And here I am."

"I have a question, if you don't mind." Asked McGonagall. Wiping away the tears before they got a chance to fall.

Kaneki inclined his head, which McGonagall took as the que to continue.

"As you're aware, no one can Apparaite inside of Hogwarts, which means you'd of Apparaite outside the gate. So how'd you get in?"

Kaneki, deciding to amuse himself, spoke honestly. "I jumped."

"Impossible!" Exclaimed Hermione and Ron in unison.

"Believe what you want but that is the truth." Said Kaneki with a tone that spoke 'and that's that'. "Any more questions?"

"Um, why's you hair white?" Asked a red Ron.

Kaneki stared at Ron and judging by his expression he was beginning to feel uncomfortable.

"To be truthful, I don't know. After a certain…incident, my hair just turned white. Must be a magical thing I guess."

"And pray I tell, what was this incident?" Asked Dumbledore.

"I prefer not to say." Replied Kaneki with a little too much bite to his words; causing Dumbledore to flinch slightly.

"What happened to your eye?" Asked Hermione gently.

"Nothing of importance." He said evenly, "If that'll be all." Said Kaneki, cracking his fingers again.

"Yes. Before you go, I'll have you follow Hermione to her classes so she may help you catch up. As you may have noticed already, but our school is hosting the TriWizard Tournaments. Before you start class, would you two be so kind as to take Kaneki up to the common room so he may change in some fresh clothes?" Asked Dumbledore, directing his question to Hermione and Ron.

"Of course!"

"Wonderful. Please come and see me if you need anything my boy."

"I'd like it if you'd stop calling me 'my boy'. You remind me of a very annoying Gourmet." Stated Kaneki calmly as if he just didn't tell one of Wizarding Britain's most powerful wizards to shut up.

Dumbledore, looking taken aback for a split second, recovered and nodded, although looked confused at who or what this 'Gourmet' is.

"Of course, I apologise." Kaneki nodded before heading towards the spiral stairs, hearing Hermione and Ron run after him.
