The train was pulling out of the station. Students leaned out the windows, waving at their parents and younger siblings, and some older siblings. Two teenage figures stood at the end of the platform, standing silently, looking at the last compartment, both eyes on a small girl with black and silver hair. The red head turned to his friend, about a foot shorter and with black hair that stood straight up, a white starburst on the front.

Kurama smiled at Hiei "Don't worry Hiei, she will be able to contact us if she needs us. Besides, this is a good opportunity for her." He watched the train wind around the track.

Hiei grunted "Hn, you just want to go with her so you can go to school there, fox, don't lie. Besides, I know she will be fine. She is strong, her powers grow daily. She won't have any troubles." Hiei watched the train take his sister away. His other sister. It had come as a shock to him to have Yukina tell them that they had a sister. One who was a pure divide of their mother and father, both fire and ice. It had been a hard journey to find her, but they had done it, with the help of their friends. It seemed he had so precious little time with her before that accursed owl had shown up with the letter. So, she was to watch after this Harry Potter kid while he and Kurama worked with some of Harry's other protectors.

He sighed and turned to see a man with a wierd eye approach them. The man spoke "I'm Mooney, you must be Hiei and Kurama. Did Rain get on the train ok?"

Hiei just frowned more. Kurama nodded to him "Yes, she got on fine. Don't mind Hiei, he is a bit protective of his sister."

Mooney nodded "I understand, come with me, we will go meet the others and talk about this common threat we seem to have."

On the train....

Rain sat watching her brother and best friend fade from sight. She would miss them, but she couldn't help but be excited as she moved down the tracks to her new school. Kurama was so jealous, how he would love to go to this school, but he was needed elsewhere. She blinked and looked to the door as it was opened. A boy, about 16 stood there, with a slightly younger girl behind him. The girl had bright red hair that reminded her of Kuwabara's and the boy had wild, untamed black hair with a lighting shaped scar on his forehead. She blinked at them both as they stared at the girl before them.

Harry had never seen her before. That she wasn't a first year was obvious from the shape of her body, but who was she. The girl, Ginny Weasley smiled and stepped forward. "Hello, I'm Ginny. Do you mind if Harry and I sit here, all the others are full." Rain just regarded the two for a moment and then nodded "That is fine." She turned back to the window, staring at the surroundings.

Harry and Ginny sat down, looking at each other. Harry spoke first. "Ummm, are you new here?" Rain nodded, not even looking at them. "Yes, I am. I'm a transfer student from Japan." They blinked, she didn't look Japanese. However they didn't question her on it. Ginny studied her. The new student was pretty, long black hair with streaks of bluish silver through it, a silver bandana covered her forehead, she had reddish eyes and wore muggle clothes. A snow owl sat in a cage next to her, sleeping.

Rain finally sighed and turned her eyes to her compartment mates. They both blushed, having been caught staring at her. "If you are going to stare at me, at least make conversation so we aren't sitting here in this uncomfortable silence." Harry and Ginny both blinked at her and she smiled at them. "Look, I won't bite your head off." Harry began to laugh "Sorry." Ginny giggled and the three fell into easy conversation. Rain asked them about Hogwarts and they asked her about her school in Japan. She was a bit vague on it, but did tell them about her friends. Kurama, Yusuke and Kuwabara, as well as her brother and sister Yukina and Hiei.

Harry blinked "You are part of triplets?" Rain nodded "Yes, Yukina looks like mother, Hiei resembles father a great deal. I am a combination of both our parents." The door slid open and two more people stood there. The boy had the same red hair and freckles as Ginny, the girl had frizzy brown hair and a nice smile. She looked them over and then looked back at Harry and Ginny. Harry smiled to his friends. "Hermione, Ron, this is Rain. She's a transfer student from a school in Japan."

Ron stared at her "You are a witch?" at her nod he frowned "What year are you?" Rain blinked "6th." He nodded and sat next to his sister. Ginny frowned at her brother "Ron is my older brother." Rain justed nodded "I figured." She turned her gaze to Hermione who sat next to her "Are you and Harry siblings?" Hermione laughed and Harry shook his head "No, Hermione and I are only children." Rain nodded and then looked out the window. She tried to remain patient. The train was traveling slow. She had inherited Hiei's speed and Yukina's healing power as well as some powers of her own in her recent training. Combine them with the powers she had perfected during her long search for her siblings, plus the Jagan she had in her forehead, she could rival Hiei.

A knock on the door revealed a woman pushing a cart with snacks. After the compartment got their snacks, they settled down and ate. Ron and Harry were having fun with their chocolate frogs. At one point, a wrapper fell on the floor and Rain leaned down to pick it up. Her necklace fell out of her shirt and she sat back up. Before she could tuck it in, Hermione leaned close and looked at the gem in the pendant. "Oh my, is that an arctic fire?" Rain looked down at her tear gem that she kept with her. "Oh, uh, yeah." Hermione just gaped at her and Ron spoke around the chocolate in his mouth. "What?"

Rain wrapped her fingers around it, and tucked it back into her shirt as Hermione spoke. "Arctic fire is the rarest gem stone ever. My parents have a fascination with gems. There are only two stones known in existance. They are called tear stones, cause of their tear like shape. One is held in a museum in France, the other is owned by a private owner who lives in Japan." All eyes turned to Rain who shrugged "Well, it was left to me by my grandmother, i always wear it" she easily lied. Ron and Harry were just staring at her. She made it sound as if she wore a simple five dollar bauble around her neck instead of a gem worth a large fortune.

She shrugged "Besides, it's enchanted. No one but the wearer can remove it from their neck. It won't accidentally fall off or anything."

The door to their compartment slid open "Well, well, well. If it isn't Potter and his little rag tag group of friends. Ahhhh, new blood. Hello there." Malfoy with his two goons stood in the doorway. Rain frowned in the direction of the cute new boy. He had an attitude, kinda reminded her of Hiei.

The group all frowned at Malfoy, an air of confusion being picked up by Rain. Malfoy turned to look at Crabbe and Goyle. "I think Pansy said she was getting our usual coach, go see if she had any problems getting it?" As they nodded and moved off, he stepped in a bit and closed the door. "Sorry. They don't know."

Harry and Ron nodded to their old enemy turned friend and he looked at Rain with pale eyes. "So, who is this?" Harry shrugged "Malfoy, meet Rain. Rain, meet Draco Malfoy. We sort of have to keep up an appearance that we hate each other. Hard to explain, but we will tell you later." Rain nodded and Malfoy took her hand, kissing it. "Pleased to meet you. I must be going though, just wanted to say hi. Gotta keep up appearances with the others."

Malfoy smiled at Rain and left the compartment calling over his shoulder "Just watch yourself Potter." and closed the door with a wink.

Harry sighed "Ok, it still takes some getting use to having Malfoy on our side, and being nice to us." At Rain's questioning look he sighed "Do you know who Voldemort is?" The others, besides Hermione, gasped and Rain nodded calmly. "Yes, I know." He nodded "Well, Draco's father supports VOldemort. Over the summer it became known to us that Draco does not agree with his father and is now on our side. However, since we started school, we have not gotten along. Now that we do, well, we just can't have him going around getting chummy with us, can we? We must keep up appearances for his sake. He will be in great danger if it is discovered he is now on our side. That is why he will insult us all year. If he says stuff to you, don't let it bother you. What house are you in, anyways?"

Rain blinked at the quick change of topic before replying. "I am in Gryffindor." They all smiled at her "Great, so are we." She smiled, a bit relieved.

Finally the train slowed, the students had changed into their robes and cloaks, stepping out of the train onto the platform. Rain saw a giant of a man calling for "firs years." Harry, Ron and Hermione all greated him and introduced the giant to Rain as Hagrid. He smiled to her and then continued to round up the first years, taking them with him as Rain followed Harry and the others.

The entered the great hall and Rain looked at the long table at the front of the room. She met Dumbledore's eyes, she knew who he was. He also knew her secret. He gave her a nod and she smiled back at him. Harry saw this "You know Dumbledore?" Rain nodded "Yes, I had to get special permission from him to come this year. I have met him once." Harry nodded and listened to the sorting hat give it's opening year speech. Rain tuned out the hat after the first few lines and looked around the hall before the last line of the hat's speech brought her shocked eyes back to look at it.

"Now Demon, witches and Wizards alike, let the sorting begin."

"Did that hat just say Demons?" Ron whispered to Harry. Harry however was looking at Rain's pale face. He laughed, misunderstanding her reaction "He probably meant Slytherin, most of them are evil gits anyways." Rain turned red eyes to Harry and nodded. "I'm sure that is what it meant. I didn't think it meant real demons." Harry grinned "As if there are such a thing as real demons." Rain smiled and the rest of supper went smoothly.

Draco watched the new girl, Rain, talking with Harry. She was cute. There was just something about her though. She was quiet and seemed to get along with them. He sighed and suddenly he heard her voice. "Stop staring at me, it's creepy." He blinked and she turned to give him a pointed look over her shoulder. He blinked at her. "What?" he said outloud.

Pansy sighed "I swear, Draco, don't you listen to anything I say?" Pansy continued on, Draco tuning her out once again.

"You can just think back to me, you know." Draco frowned "How can you do this?" Rain smiled down at her food "Family trait. Why were you staring?"

Draco just stared at her head "Ummm, I think you are pretty, actually." Her soft laugh floated through his head "Thank you. You are not bad yourself." With that he felt her presence leave him, not having realized it was there in the first place.

He finished eating, watching her from under his lids. She finally stood up and gave him a quick glance, her voice coming to him again "Good night, Draco. Sleep well." With that she was gone, following the others to the Gryffindor tower.
