Chapter 1

At night,

Near Hagrid's cottage a powerful whirl of wind picked up, causing many leaves, pebbles and twigs to flying around in a circular motion, grabbing the attention of many who were a sleep.

"What's going on outside?!" Hagrid yelled as he heard a bunch of trees swishing, as leaves, twigs and pebbles, occasionally rocks, hit his door. Hagrid swung his leg on the end of the bed and walked toward a window to see the commotion, getting his answer when a rock smashed his window, hitting him square on the forehead.

"Merlin's beard!" Hagrid exclaimed as he rubbed his forehead, before looking through the window to see a sudden light starting to glow in the Dark Forest, becoming brighter and brighter.

As everyone woke up to look through the window to see what happened, one question went through their minds.

What's going on?!

After five minutes the light had dimmed, before it was gone, along with the wind going down.

After waiting a minute to see if everything was safe Hagrid walked out of his cottage and walked towards the forest where the light came from. He was careful to see what he would step on as he continued his way through the forest.

He gasped at the sight in front of him. There was a small clearing full of mostly grass along with a few leaves, branches, twigs and rocks. In the center of the clearing was an injured blond child.

Hagrid quickly ran up to the child and kneeled down to look at the boy's condition.

The boy was blond (not spiky) with sun-kissed tan skin with three whisker like scars on each cheek, along with beautiful blue eyes. He wore very large clothes from shirts to pants to shoes to headband.

The boy was on his hand and knees as his right hand was clenching his left chest. Hagrid didn't have a good view of the boy but he could tell, he was injured from the cuts and blood on the clothes aloud with blood dripping on to the ground.

"Hey, you alright?" Hagrid spoke to the child. The blond turned his head to look at Hagrid, giving Hagrid a view of blood coming from the blond's mouth to his chin to drip on the grass.

"W-who are y-you?" The blond stuttered.

"I don't think this is the time for introductions, I better take you to Madam Pomfrey." Hagrid said picking the blond up, before he could run towards the school Dumbledore and a few teachers showed up to see what had happened.

"What happened and what is with that child you have in your arms?" McGonagall questioned.

"No time for that, we have to take him to the hospital wing!" Hagrid spoke, before running to the hospital wing with the staff behind him.

"I'm alright." The blond spoke, softly struggling from Hagrid's grasp.

"There's no time to be acting strong! You have to be treated before you lose too much blood!" Hagrid yelled before he made it to the hospital wing. "Madam Pomfrey!" A woman came out of a room with a robe over her nightgown and quickly ran over to Hagrid as he placed the child down on a random bed.

"What happened?!" Madam Pomfrey gasped from the state the child was in.

"I don't know, but you have to treat him!" Hagrid yelled as the other staff behind him surrounded the bed to look at the boy.

"I'm fine." The blond spoke slowly sitting up, only to be pressed down against the bed by the woman who he found out is Madam Pomfrey.

"Lay down, if you move you'll lose more blood." She spoke moving her hand away as she used her wand to scan the body. After a few minutes of scanning she looked at the results that appeared above her wand. "This can't be right." She whispered.

"What is it?" Dumbledore spoke for the fist time.

"Is he going to die?" Hagrid spoke nervously.

"No" She spoke. "He's recovering, faster than a normal person should."

"I told you, I do not need help. I am fine." The blond said sitting up, before whipping the blood off his chin with his large...clothes. Naruto stared at his clothes, as the adults thought he was staring at his blood. "What happened to me?" He spoke as he examined himself.

"I'm not quite sure." Hagrid spoke.

"Mirror" The child spoke, which Madam Pomfrey quickly picked up from her desk to him. When the male saw his reflection he gapped. "This can't be right."

"What do you mean?" McGonagall spoke.

"I can't actually look like this."

"Are you talking about the blood?" Dumbledore asked.

"I don't care about the blood! I want to know how I became a child again!" The child shouted.

"E-e-excus-se m-me?" Quirrell stuttered.

"I'm a kid! This is not right!"

"Then would you quiet down and tell us who you are before you confuse us anymore." Snape spoke for the first time.

The child turned to Snape before glaring at him, not affected by Snape's own.

"If you must know I am Naruto Uzumaki, I'm 16 years old, well I was, and I was currently on a mission, but as you can see I am being delayed." Naruto spoke stilling having a glaring contest with Snape, that is until he examined everyone, who all had a startled look on their face as they heard his actual age. "Can you tell me who you all are and where I am?"

Dumbledore smiled a little before he answered. "I am Albus Dumbledore, headmaster of Hogwarts."

"Minerva McGonagall"

"Q-Q-Quirinus Q-Quirrell"

"Severus Snape"

"Rubius Hagrid"

"Poppy Pomfrey"

Naruto nodded before giving Dumbledore a curious look. "Hogwarts? Is that where I am?" Dumbledore nodded. "Is it an organization?" Dumbledore shook his head.

"It is a school."

"School?"

"He doesn't know what a school is." Snape sneered, that caused Naruto to glare at him.

"I'll have you know I do know what a school is. I have graduated the academy." Naruto spoke.

"But you are not even 18 to go to 7th year." McGonagall spoke. "And how is it that you call yourself 16 when you obviously look to be 11 years old."

"That is what I am confused of also. What country am I in?"

"England of course." Pomfrey spoke. "You do not know where you are?"

"I don't even know where England is located." Naruto spoke pulling out a map from his baggy pants pocket. He unfolded it before spreading it on the bed in front od him to have a full view of it, confusing the staff around him. "Hm... I do not see England in this map." Naruto glared at them. "Are you lying to me?"

Quirrell shook his head.

"This is most confusing." Naruto spoke, starting at his map, looking over once more to see if there is a village at least that is called England, but he couldn't find anything.

"Where do you come from?" Dumbledore asked.

Naruto looked at Dumbledore, before folding his map back into his pocket before looking at them. "I am from the Land of Fire, in the village of Konohagakure."

"Land of Fire?" Hagrid asked.

"It's just a name, not a place literally full of fire." Naruto said answering Hagrid's question.

"I apologize, but we have not heard of your country either." Dumbledore spoke, causing Naruto to think.

"If I have not heard of your country then it could be a hidden country, but it's not in the map and they seem to not know the Elemental Countries meaning..." Naruto was speechless as he found his answer.

"Mr. Uzumaki?" Dumbledore called out.

"... It would seem that I am in another...dimension." Naruto said thoughtfully.

Almost all the professors gasped. "How is that even possible?!" McGonagall questioned.

"I...do not know." Naruto thought carefully. "What am I supposed to do now?" When Dumbledore heard Naruto said the question he had a smile on his face.

"If you have nothing to do anymore, you could attend Hogwarts as a first year." This grabbed the attention of everyone.

"Headmaster, you can not be serious. The school year will start tomorrow and we don't even know if he has any magic." McGonagall said.

"What?" Naruto asked.

"Magic, as in causing things to fly, turning things into other things ect." Hagrid spoke.

"Oh are you talking about chakra?" Naruto said.

"C-c-chakra?" Quirrell stuttered once again.

"It is a mould of physical energy and spiritual energy, which is called chakra. I can make clones of myself, dispel illusions, turn myself into someone else and a lot of other things." Naruto grinned happily for the first time.

"Then it's settled, you will be entering Hogwarts School of Witchcraft and Wizardry." Dumbledore announced.

"Eh? Witchchraft? Wizardry?" Naruto repeated the two words.

"Yep, this school teaches children with magic how to use them properly." Dumbledore smiled.

"I didn't know they exist." Naruto said.

"Then what are you in your world? Snape said.

"A ninja, of course." Naruto easily said.

"A ninja?! You mean an assassin?!" McGonagall exclaimed.

"Yeah, so?" Naruto said, not seeing the problem at all.

"We can't have an assassin in a school full of children!" Madam Pomfrey exclaimed.

"I only kill people when I am assigned to by my leader, but seeing as I am not in my dimension Dumbledore is the leader for he is the head of the school that I will be attending." Naruto said.

"Me?" Dumbledore said pointing at himself.

"Of course" Naruto nodded, causing Dumbledore to smile.

"Well then I guess everything is alright." Dumbledore said, looking at everyone. "We should all go to sleep for tomorrow night's event."

Everyone nodded as they all went out of the hospital wing to their rooms, leaving Naruto alone to sleep.


In the morning,

Naruto was walking around in the hallway looking around, as the staff got ready for the arrival of the students.

"This place is a bit large for a school." Naruto commented, as he continues to walk around the halls.

When he made it to the Great Hall he saw some teachers, along with Dumbledore, helping with the decorations.

Naruto walked towards Dumbledore who was lighting hovering candles, and tugged on his robe.

"Hm? Oh, good morning Naruto. Is there something you need?"

"No, I was just wondering if you need any help with the decorations?" Naruto asked.

"If you like, can you set the plates, napkins and utensils with some of the teachers?" Dumbledore pointed to a cart of plates and other things, with a few teachers occasionally taking a few to place on each table.

"Of course, do you wish to do it as quick as possible?" Naruto asked.

"If you can, because later I need someone to clean the chandelier." Dumbledore spoke looking up at the large chandelier above them.

"Understood" Naruto said, before making a few quick hand signs. "Shadow Clone Jutsu!" Multiple smoke appeared around the room, surprising some, when the smoke cleared about 100 Narutos were standing.

"All of you make five groups of 20!" They all nodded and quickly they all ran to a group, careful to not push anything or any of the dumbstruck teachers as they did so.

The original nodded at them all before barking orders.

"The group in the middle with clean the chandelier!" Pointing at the chandelier above them. The group all yelled "Hai!" before running on walls and ceilings with cleaning utensils to start cleaning.

"Each group will be taking over a table and placing the plates and such properly on the table! Is that understood?!" Naruto yelled to the rest.

"Hai!" All of the clones yelled before going to a table and doing their job.

As the event happened shocked looks were on everyone's faces, except for all the Narutos.

"This is amazing!" Dumbledore exclaimed happily, patting the Naruto beside him on the head. "With all the help we have we'll be absolutely prepared for the students." He then had a look of realization on his face, when he noticed Naruto still wearing the clothes that were too large on him. "I forgot, you are one of the students too. You need to get your school supplies. Who will I send to guide you?"

"Sir, you do not need to worry, I'm pretty sure I can manage." Naruto said.

"No, you will not leave by yourself. You will need help to know which store you need to go for school supplies." Dumbledore spoke, still thinking until he heard the entrance door of the Great Hall opened to reveal a shocked Snape. He had a mischievous look in his eyes before he walked up to Snape.

"Good morning Professor." Dumbledore said happily.

When Snape quickly recovered from his shock of seeing 100 of Narutos in the room he quickly greeted Dumbledore. "Good morning Headmaster."

"I have a request for you. Do you remember Naruto Uzumaki from last night?" Snape glared at Naruto, who once again glared back.

"Yes"

"Good, I wish for you to take Naruto to Diagon Alley to buy school supplies." Dumbledore smiled, seeing the shocked look on Naruto and Snape's face.

"I refuse" Snape said blandly.

"I agree, I can take care of myself. There is absolutely no reason for me to walk around with him for such trivial things." Naruto pouted.

"It's not really an option. The other teachers are still busy, and since I know that you, Snape, has finished his paperwork yesterday you will guide Naruto."

"What about the money? I do not have enough money for him and I'm pretty sure the money he has are absolutely different from our own." Snape said trying to escape.

"No problem, I have a small bag of galleons right here." The headmaster said showing them the small bag.

"..." They two were speechless not knowing what else to say to protest currently.

"Now then off you two go." Dumbledore said pushing the two out of the room, that is now ready for the students to arrive.

After the door closed, the two glared at each other.

"How are we to get to Diagon Alley?" Naruto asked, looking away from Snape.

"We will be using apparition." Severus said as he raised an arm to Naruto.

"What?" Naruto said, looking at Severus's hand.

"Hold on to my arm hand and I will teleport both of us to Diagon Alley." Snape sneered at the thought of being touched.

"Whatever" Naruto said before he held Snape's surprisingly warm arm before they were teleported to their destination.


Diagon Alley,

They both made their way to Ollivanders as it was one of the last stops they need to make before they could leave to Hogwarts.

As they went in Snape sat on a chair as Naruto went up to the counter waiting for someone to come out from the back so that they could get his wand.

"Hello, are you here for your first wand?" Ollivander asked coming from one of the back shelves hidden doing whatever, receiving a nod from the blond.

"Alright then..." Ollivander scanned at a random shelf full of many long boxes, before pulling out a box and walked towards the counter.

"Here" Naruto took it before giving the man a confused look on his face. "Give it a wave." Ollivander spoke.

"Oh right" Naruto waved the stick only for a vase above Snape to shatter, causing Snape to glare at him as some shards were on him along with some flowers as he was drenched in water. Naruto laughed nervously before turning after Snape cleaned himself up with a flick of his own wand.

"Frankly not" The old male spoke taking the wand back into its box, leaving it on the desk to put back later. He went back into another random shelf to pull out another box.

After about 10 wands, Ollivander had a thoughtful look on his face.

"Mr..." Ollivander realized he doesn't know his customer's name.

"Naruto Uzumaki" Naruto spoke.

"Mr. Uzumaki, what would you say would be your most fond animal?" Ollivander asked.

"Hm..." Naruto thought of saying frogs and toads but remembered about the fox and how they kind of got along bed before answering. "I guess I would have to say foxes. Why?"

Ollivander nodded, ignoring the question before walking towards the back shelves. When Ollivander came back he had a hesitant look on his face. "I wonder" When he placed the box on the desk, he opened the box to reveal an orangish-red wand.

"Hm?" Naruto looked at the wand in question.

"It is quite unique, it was made by my grandfather. The wood is cherry blossom and the core is a fang from a unique fox."

"Unique fox?" Naruto questioned.

"Yes, it was a baby kit with nine-tails." Ollivander said happily.

Naruto looked at the wand before he casually picked it up from its bed and gave it a wave. At first Naruto felt a warm sensation coming from it until the room was filled with it.

Everyone, even Snape, relaxed from the warmth, after a while the warmth vanished.

"That was quite unique also." Ollivander spoke contently before muttering something as he realized something. "Curious, really curious." He then took the wand from Naruto, placed it back into its box, wrapped it with a ribbon before pacing it to Naruto as Snape walked up to the counter with the bag of coins.

"How much will that be?" Snape asked.

"9 galleons, seeing as how unique it is." Ollivander gladly took the coins before waving them good-bye as they left.

"How many more places do we need to go?" Naruto asked looking at Snape with his big blue eyes.

"One more." Snape spoke not looking at Naruto's eyes.

When Naruto was going to look forward that's when he bumped into someone.

"I'm sorry" Naruto spoke after he landed on his butt. When he looked up to see who he bumped into, his big blue eyes met grey colored ones.

The man he bumped into didn't speak as he examined Naruto. At first when he saw Naruto's attire he was going to say something rude until he noticed Naruto's big blue eyes and his bare sun-kissed neck, along with his other physical features such as Naruto's blond soft hair, small pouty lips and button nose. The man could feel his erection starting to twitch.

"Good morning Lucius" The two heard Snape speak.

"Good morning Severus, who is this?" The man, now known as Lucius, asked, gesturing to Naruto who was now standing up as he brushed off invisible dirt from him.

"This here is Naruto Uzumaki, he appeared yesterday" Literally Both Naruto and Snape thought in unison. "and after clearing a few things of his appearance he will now be attending Hogwarts."

"Naruto Uzumaki" Lucius tested the name to himself quietly and quite like how it sounds.

"And who are you?" Naruto asked, placing his full attention towards Lucius.

Lucius could feel his erection twitch once more feeling the child staring at him with such innocence.

"I am Lucius Malfoy, head of the Malfoy family." Lucius said calmly.

"Lucius?" Naruto repeated the name to test it himself, not realizing how sweet it sounded to Lucius's ears. "Your name sounds really fancy." Naruto grinned.

"Thank you" He nodded to Naruto before looking at Severus. "It was a pleasure meeting both of you, I would stay a little longer to speak with you two but I have a meeting to get to." Lucius nodded to Severus, who nodded back, and smiled at Naruto, who waved at him happily.

As Lucius left the pair continued to walk.

"Hey Severus-"

"You are to call me either Professor or sir." Snape said, cutting Naruto's sentence.

Naruto pouted. "Professor Snape, how do you know Lucius?"

Snape sighed at the name before answering coldly. "I don't see why it concerns you."

"You don't need to be rude, I was just curious."

The potions master didn't say anything as they continued to a shop.

"Magical Menagerie?" Naruto read the sign. "Why are we going in a pet shop?"

"It's optional to either have one or not, but it's most preferred to have one so they could deliver it to and/or from you." Snape spoke. "You can have only an owl, a cat or a toad, there are some exceptions though."

"Do you think they have a fox?" Naruto looked at Snape.

"I'm not sure. You would have to go look." Snape spoke calmly, walking into the store along with Naruto who quickly looked around the store.

After looking around the shop he pouted not finding a single fox in the pet store.

"Just hurry up and pick one already." Snape snapped, not liking how loud and annoying the animals' made.

"Fine" Naruto mumbled before looking around the store once more. He then noticed a black kitten staring at him with red slit eyes. "Hm?" Naruto went up to it and took a closer look at it. "Strange, I didn't know cats can have red eyes." Naruto spoke to himself.

The kitten continued to stare at him before giving a cute reply. "Mew~!"

Naruto grinned at it before opening he's cage and scratched him on the head. He laughed when it purred as it pressed his head closer to Naruto's hand.

"I am guessing that you have found your new pet." Snape spoke as he walked up to Naruto.

"Yep! He's so cute and his fur is so silky!" Naruto commented of the kitten.

"Mew~!" The kitten replied before placing both its paws on a confused looking blond's neck before moving up and licked Naruto's lip. Naruto's eyes widened before he calmed down, thinking it was just showing affection as it continued to lick his face.

'Being molested by a kitten, that's quite strange. But only this buffoon would accept such a thing.' Snape thought in his head before turning to go to the counter with Naruto right behind him.
