Harry Who?

In the four weeks leading up to the day they were to leave for Hogwarts the four kids learned more about the world they were in. They found out the Mr. Weasley worked at the Ministry of Magic in a department called the Misuse of Muggle Artifacts. They also found out that he was curious about anything that muggles used, much to Mrs. Weasley's dismay. They also learned that Percy was a stuck-up follower of rules, Fred and George were the complete opposite of him being pranksters, Ron being the youngest boy got all of his older brothers hand-me-downs, and Ginny was the youngest of the Weasleys children and their only girl.

On September first, the day they were to going to head off to Hogwarts, the family was scrambling to make sure they had everything packed. When they had gotten outside they saw two cars waiting for them.

Mrs. Weasley told the four new members of the family that Arthur had gotten permission to use them, so they could get to King's Cross easier. Mrs. Weasley and the four girls piled into the first car, while all five of the boys got into the other one. The drivers put the students' entire luggage into the trunks of the two cars.

When they got to King's Cross the two drivers got some trolleys and put the trunks on them. As the group walked into the station Kaoru noticed the same boy from the day they had gotten their school supplies staring at them.

Mrs. Weasley stopped and asked "Now, what's the platform number?"

Ginny answered her "Nine and three quarters!" She then said "Mom, can't I go…"

Mrs. Weasley sighed "No Ginny, your not old enough. Percy you go through first."

Percy ran toward the barrier between platforms nine and ten; in the blink of an eye he was gone. Mrs. Weasley sent Fred and George through next, at that moment the boy with glasses had come over to them. He asked Mrs. Weasley how to get on to the platform and she explained to him that you just head at the barrier and you'll get there. After he had gone through Mrs. Weasley sent Ron through, followed by the new members of the family.

On the other side of the barrier was a red steam engine. Miyako looked around and saw the twins helping the boy they had meet load his trunk onto the train. Mrs. Weasley led them all to the end of the train where everyone loaded their trunks onto it. The four new family members were holding onto their new pets as Mrs. Weasley called for the twins and Percy. She then proceeded to hug and kiss each one of them on their cheeks and fuss about their appearance.

Fred then spoke up "Hey mom, guess what? Guess who we just met on the train?"

George continued "You know that black-haired boy who was near us in the station? Know who he is?"

"Who?" asked Ron annoyed.

In unison the twins said "Harry Potter!"

Ginny screamed loudly and then begged Mrs. Weasley to let her go see him. She told her no and proceeded to warn the twins not to bother him.

The train whistle blew and everyone got on the train waving goodbye. The girls told Ginny they would write to her when she started to cry.

Kaoru led them through to the compartment they had put their trunks in. When she opened the door she saw the boy from the platform sitting there. She shrugged and walked in sitting down across from him. Ron and Momoko sat down next to her, Miyako and Takaaki sat down next to the boy holding hands. The twins then showed up telling them they were going to sit with a friend of theirs. Before they left they introduced themselves and Ron.

The boy then asked Ron who the others were. Ron told him that the three girls were his cousins from overseas and that the boy was Miyako's boyfriend. Ron then asked him if he really was Harry Potter and the boy told him he was showing him his scar.

"Can I ask one thing, why are you guys so excited to meet him?" Momoko asked with confusion.

Harry looked at her puzzled "You guys don't know, I thought everyone in the wizarding world knew who I was?"

"We're not from England, so we don't know who's supposedly famous and who's not" Takaaki told him.

Ron then gave his cousins a brief summary of what had made Harry famous.

"That's horrible, why would anyone want to be famous because a psychopathic murder couldn't kill you?" Miyako said in disbelief.

Ron was stunned by this comment, and then looked at Harry "Sorry, I never looked at it like that."

Harry shrugged and told him it was all right, because he himself had just found out all of this a month ago.

Ron then reached into his pocket and pulled out a sleeping, fat gray rat. "This is Scabbers, he's my useless pet rat," he told Harry.

As soon as Scabbers was in sight Miyako and Takaaki's cats started to try to get him. Both Miyako and Takaaki yelled at them in unison "How many times do we have to tell you two, DON'T GO AFTER SCABBERS!" As soon as they heard their owner's angry voices they calmed down, looking eagerly at the rat.

Harry laughed at the reactions of the two cats.

The group began to discuss different things to pass the time. They started talking about their families, followed by what it's like living in Japan, and finally how Harry had found out about being a wizard.

Near the end Kaoru said that she would like to teach Harry's relatives a lesson. Harry and Ron were still amazed by what the four had told them of their homeland. The other three were still laughing at Harry's Uncle's reaction to all the letters and Hagrid's arrival.

An hour and a half after the train left the station a dimpled woman slid the door of their compartment "Anything from the cart?"

Harry stood up, but Ron said that his mom had made them all sandwiches. Harry then went into the corridor and came back about a minute later, his arms full of a wide variety of snacks. The other five pulled sandwiches from their pockets, Ron grumbling about the one he had. Harry offered to share his snacks with them all. They accepted and dug in. They ate Chocolate Frog's giving Harry all of the cards and had a fun time watching each others reactions as they ate Bertie Bott's Every Flavor Beans.

There was a sudden knock on the door as a round-faced boy walked in asking if they had seen his toad. They told him no, but it should turn up eventually.

After the boy had left Ron pulled his wand out saying he was going to try a spell on Scabbers. As he raised his wand the compartment door opened again. It was the toad less boy again, but this time he had a girl with him. She was already wearing her new Hogwarts robes.

She asked if anyone had seen a toad, because Neville had lost one, apparently the boy's name. She had a bossy sort of voice, lots of bushy brown hair, and rather large front teeth.

They told her that they had already told him that they haven't. She then told Ron that she wanted to see the spell he was about to do, Ron then cleared his throat.

"Sunshine, daises, butter mellow,

Turn this stupid, fat rat yellow."

Nothing happened to Scabbers. Then the girl started to say that she didn't think it was a real spell, how she had read all about Hogwarts from their school books, that she was a muggle-born, and finally that her name was Hermione Granger. She said it all so fast that none of them were able to interrupt her. At the end she asked them who they all were.

They went through the same introductions as when Ron did them. Hermione blushed at hearing that Miyako and Takaaki were dating and then gasped upon hearing out who Harry was. She then told him that he was mentioned in three different books, the house she wanted to be in, and finally leaving to help Neville find his toad.

Ron then proceeded to explain to everyone about the different houses at Hogwarts and how Slytherian was where all the Dark Wizards came from.

When he got done the door of their compartment opened again. This time it was a pale boy with a pointed face, he was flanked by two larger boys that looked like they had brains the size of a squirrels (I apologize to all squirrels for the insult).

The pale boy looked at Harry and asked him if he really was Harry Potter. Harry told him that he was, while eyeing the two on either side of the boy. The boy the introduced himself as Draco Malfoy and the two on either side of him were named Crabbe and Goyle. Ron laughed at them. Draco then looked at him saying that his dad had told him all about the Weasley family. He then turned back to Harry telling him that some wizarding families were better than others, and offering his hand in friendship. Harry told him that he knew how to make good friends without help. Draco turned pink and proceeded to insult both Harry's dead parents and the Weasleys.

Both Harry and Ron stood up, but Kaoru, Takaaki, and the two cats lunged at Draco and his cronies. Takaaki tackled Crabbe and started pounding any part of him he could reach. Luna and Artemis were scratching, clawing, and biting any part of Goyle within reach. Kaoru had slammed into Malfoy so hard that they fell into the corridor, were she started to hit him in the head as hard as she could.

Miyako pulled Takaaki off Crabbe, while Momoko grabbed Luna and Artemis, and it took both Harry and Ron to restrain Kaoru. The three badly beaten boys managed to pick themselves up and run down the corridor away from them all.

"Bloody hell, what was that about?" Ron asked in shock.

Kaoru wrestled herself free and turned to Ron "What do you mean, what was that about? That BAKA insulted our families, he deserved that and more."

At that moment Hermione Granger came in "What HAS been going on?" looking around at them all. She gave a yelp of fear when she saw the angry look in Kaoru's eyes and ran out of the compartment.

After they had managed to calm her down, Ron asked how Harry knew Malfoy. Harry told him about meeting him in Diagon Alley. Ron then explained to them all what he knew of the Malfoy's. After Ron was finished talking, Miyako told them that they needed to get in to their school robes.

At that moment a voice echoed through the train: "We will be reaching Hogwarts in five minutes. Please leave your luggage on the train, it will be taken to the school separately."

A/N: There were some surprises in this chapter. I bet you wouldn't think Kaoru would get into a fight on the train even before they got to Hogwarts, let alone Takaaki joining in.

The reason Kaoru went after Draco is kind of apparent she and the other girls have started to think of the Weasleys as their family.

Now the reason Takaaki joined in was because he has always hated people who pick on others. Evident in the first episode he was introduced in for the show, trying to protect a young Miyako and her friends from bullies.

By the way after this chapter Neville's toad will never be mentioned again. It was a convenient plot device for introductions. If I'm thinking right J.K. Rolling didn't even use it more than two or three other times through out the book series.

I'll ask again please review.
