Author's Note: (Please read before reading the story) Alright, I've decided to write a Harry Potter and Higurashi crossover, weird crossover, I know. But since I've been watching that show non-stop, I've decided to do this. It's so interesting. Anyway, I'm not sure if I stayed in character with all of them, but I tried to, I really did. So if they do something a little out of character, sorry, I'll work on that.
Anyway, I have Rena go to school in Hogwarts in here, just to let you know. Now you are probably already giving me weird looks, wondering why…you'll see… Enjoy.

Chapter 1: Rena.

"Rena?" Harry questioned, it was after dinner, everyone was going to their common rooms, they really weren't suppose to be out this late. He better find her soon, before Finch gets to her. "Rena!" He called down the hallways, his voice echoing, it was practically half-empty, only a few students were around, but they were all walking back to their common rooms, where he was suppose to be right now.

Yet he cannot help it, he had to find his new friend, wherever she may be. Lately, Harry began to worry about her. There was something…not right about Rena, not right at all. She was always a sweet girl, but she's been pretty cold the past few days. Acting strange, not herself, it sometimes scared him and his friends.

"Rena…" he said once again, only softly. The whole hall was getting darker to him, the lights were dimming. It's officially time for everyone to go to bed, or finish up on some homework, whatever. But whatever it is, they weren't suppose to be out.

Could Rena already be back at the common room? Could she be there?

Maybe she was. Harry ended his search for her at the halls, he made his way back to the Gryffindor common room. Every little step he took, it just felt like a mile, instead of a foot. Felt like it was taking him forever to get where he needed to get to. The halls were eerily quiet, and darker then usual, Harry never had a problem with it, but now it was given him the chills. He just wanted to make it safely back to the common room, hoping that his new friend was there too.

"…Harry?"

"Hn?" Harry jerked his head back, almost enough to get him whiplash. He couldn't really help it, he was getting creep-ed out, even if he didn't exactly understand why. But his gaze fell back, and there she was - Rena.

Wearing the school uniform, along with her robe. Her orange-brown bangs hid most her face, her eyes were focused on the ground, whereas, Harry's were focused on something else. Something that easily caught his eye, and raised the whole 'creepy tension'. She was holding some sort of knife…huge knife, more like a-

"Is that…a cleaver?" Harry asked, trying gulp down that huge lump in his throat right now.

"Machete." Rena answered, but the blade certainly didn't look like it, it was a little too small for a machete. It looked more like a giant cleaver, as Harry mentioned before.

"What are you planning on doing with that?" Rena didn't answer him, the blade was really making Harry feel uncomfortable, the way Rena was just standing there, the fact that the whole place was rather dark and there was this…tension. This sort of tension Harry really couldn't describe. Fear and Paranoia. All rolled up in one.

"Rena?" He asked. He got no answer from her, she continued to stare at the ground, her grip was firm on the handle of the blade. "…Rena?"

~ Typical day for the first day of Hogwarts. All the shaky first years, trying to find their way around the castle for their first class of the day, a couple of second years were grateful they remembered their way around from last year.

Harry and his friends arrived at Transfiguration, only to be greeted by a rushing crowd, and a tiny shriek. Harry turned back to see a girl fall on a Hufflepuff girl, knocking both of them down on the floor.

"Ow…ow…" both girls stood up from the floor, the Hufflepuff seemed rather annoyed, even if the other girl did apologize, the Hufflepuff just gave her a dirty look and proceeded her way to her table, with the rest of her classmates.

The girl sighed, frowning, she knew that the Hufflepuff girl didn't really appreciate being knocked over by her. She just quietly walked to the table where all the Gryffindors sat.

A foreigner. Harry thought, from the looks of it, she was Asian, looked young… like a first year.

Made sense, Harry has never seen her around before, but she looked a little older than a first year, maybe a third year, but not first. Still, Harry didn't recognize her, and she must have been in their year, since she was in their class. Confusing, confusing…

This girl was introduced as Rena Ryuugu. Everybody must have been as confused as Harry, seeing how they never really had a new student. At least…not one that bumps up all the years. Rena didn't really like the attention she was getting, everyone was staring at her…

"Another Mudblood," mumbled a couple of Slytherins, and their fellow students laughed at it like a joke. Of course, Rena didn't know what that meant, so when she overheard the Slytherins laughing, she just turned to them, and smiled friendly as she could. They didn't return the smile, just stared at her. They send looks at each other, every time Rena tried to do say something nice to them, like introducing herself, in the hopes of making a new friend.

Harry felt sorry for her.

Knowing that she had no idea that Slytherins and Gryffindors don't mix. That still didn't stop her from trying.

Later that day, Hermione decided to talk to her, as a good gesture. After all, it seemed like Rena was on her own, she needed to make some friends. Harry and Ron departed from Hermione, and she walked to her next class with Rena, they had it together.

"How is she, Hermione?" Ron asked, the trio were all done with their first classes, they were relaxing and starting on some homework at the Gryffindor common room.

"She's nice," She answered, starting on her report for Snape's class. "Nicer than anyone I've ever met, but it's a bit hard to understand her with her Japanese accent." She dipped her quill in her tiny bottle of ink, "She's trying hard to learn though,"

"She's strange," said Ron, struggling with his report, "She tries to make friends with a couple of Slytherins, when they were clearly making fun of her."

"Well she's new, she didn't know." Hermione opened her potions book, checking up on her notes. "She probably couldn't understand them either, she is from another country, after all."

"Hermione-chan!" The three turned their attentions to the familiar looking girl, who ran up, greeting Hermione. "There you are." She said, "I've been looking for you - I need help with our assignments," Rena, adjusting to her new school wasn't easy. She had no idea about magic or what it does, she didn't think it was suitable for her to skip ahead so many years…but it happened. For what reason, she didn't know. All she knew was, she had gotten that letter, on that day…

"Oh…" Rena switched from outgoing to shy, once she saw Harry and Ron. "Hello," She said, her voice soft. The room filled with awkward silence so the two just greeted her back, before turning back to Hermione, as she agreed to help Rena with the assignment they had. "You two should really work on your assignments too." Hermione said to Ron and Harry, not taking her eyes of her work. Rena didn't say anything, she kept her head down, working too.

"We're working!" said Ron, when it was clearly a lie, the two were mostly spending the time discussing Quidditch, than anything. They continued discussing it.

"How do you do it, Harry?"

"Do what?"

"Catch the Snitch so fast, you're incredible!"

"It runs in my family, remember."

Rena couldn't help but drift away from her schoolwork, and overhear Harry and Ron's conversation. It really interested her. Of course, she couldn't understand much of what they were saying, didn't know a few words. She could only make out a few words. She learned that they flew on brooms…something about goals… A sport?

"We should practice after this," Harry said, and Rena finally piped up.

"What are you going to practice?" She asked, hoping that they weren't offended for her eavesdropping.

"Quidditch." Harry answered, "Do you know what that is?"

Rena shook her head, Ron flashed her weird looks. She was like a muggle. Clueless about the things in the wizard world. But then again, that's what she was, a muggle, till she got her letter, conforming her as a witch…

"I would really like to come watch you practice," She admitted, "I don't know this sport…but I want to learn, I need to get know this place more, after all." She giggled, "Is it all right, if I come and watch?" She continued smiling, awaiting her answer. Harry didn't know what to say, the question was so sudden…but he thought that it probably couldn't hurt much. Rena is just trying to sprout her wings, Hermione was already helping her with that. Maybe he should do the same.

A friendly smile appeared on Harry's face as he said, "Sure," Rena was delighted.

~"Do you know how to fly a broom, Rena?"

"I'm afraid not…" Rena blushed a bit, embarrassed by the fact that she knew very little about how to fry, she's also afraid of heights a bit, not sure she would make it high enough.

She had already watched Harry and Ron's older twin brothers, George and Fred, fly around the brooms. They made it look so easy, and so fun.

"They're teaching all the first years how to fly brooms." said George,

"We should send her to her class to learn," joked Fred, "But you might fall, and break every bone in your body." The red-headed twins laughed. Yet Rena didn't find it at all funny, she was now afraid to ride a broom.

"They're just joking, Rena." said Ron, "You'll never know unless you try it."

Rena nodded, and watched at Harry flew around in his broom, practicing with Ron's brothers around the goals of the Quidditch Stadium. She and Ron sat in the bleachers.

"Why don't you go and practice with them?" She asked, "Aren't you on the Quidditch team too?"

"No…" Ron sighed, "George and Fred are the only ones in my family who are on the Quidditch team right now."

"But…you want to be?"

"Huh?" Ron give Rena a questioning look.

"Don't you want to be on the team too?" Rena could tell from his face, from his expression, that he was actually considering it. His face looked like he was in thought, deep thought about how he wanted to always be on the Quidditch team, how he always dreamt of having the Quidditch World Cup presented to him…

Rena could tell.

"Why don't you go fly with them, I know you want too." Rena stood from her seat, grabbing Ron's hand and hauling him up to his feet. "Don't worry about me! I'll just sit here and watch."

"Er, what?" Ron stumbled onto his feet, watching his step, making sure he wouldn't fall off.

"Go play with your friends." Rena said, she smiled.

"Really?…" Ron frowned, he knew that his friends were trying to get Rena used to be here, even if it meant sticking by her all the time, but truth was, he really did want to play.

"Yes!"

He couldn't argue with that. Already, three times, she said it was ok for him to go off and practice with Harry and his brothers. He waved good bye to her, grabbing his broom, and flying off to the Quidditch Stadium. If he was going to join the team one day, he might as well get really good at it till then.

~ "That was great!" Over the time of watching them all practice, Rena got so excited, she didn't mind wanting to try flying a broom. But of course this meant she was going to have to learn how to fly, little by little. Maybe she'll get transferred into the class for first years learning how to fly the brooms. "You flying everywhere, Harry was like 'woosh!' and Fred was like 'whoooa!'" Rena threw her arms around at every woosh and whooa she made. Hermione giggled, she found it adorable.

Once more they were all at back at the common room, the day was now ending, the sky turned to a pitch black outside. Everyone was just sitting around by the fire, and resting. Hermione was writing a letter to Viktor Krum(Ron was trying hard to hide his jealousy).

"Is Viktor-kun your friend?" asked Rena, peeping over Hermione's shoulders and trying to read the letter she was writing. Hermione just nodded, eyeing Ron from her letter. Then that's when Rena giggled, "Ooh, is he your boyfriend, how cute~!" Hermione's cheek turned to a shade of pink, she cleared her throat, and finished up her letter.

"Is there a postal near-by, how are you going to deliver that letter?" asked Rena, watching Hermione rolled up the parchment, and tying it together with a string.

"Around here, we have our owls deliver our mail." She said, and that's when Rena let out a squeal.

"Oooh! A owl, cute so cute~!" She jumped in place, "I want to take it home, I want to take homeee~!" She singed, clapping her hands together and acting like a little girl. But that's who Rena reminded Harry and his friends - a little, carefree girl.

"You act as if you never seen these kinds of things." Hermione joked,

"Oh, I never do…really, not around where I live." Rena sat in a armchair next to Harry and Ron. "Not in…Hinamizawa."

"Is that where you live?" Harry asked, "Hina…mizawa." It was quite the strange name he has ever heard for a town, but he has heard even weirder, thanks to this wonderful wizard world he lived in.

Rena nodded, "Yes, that's where I live. My family is very important there, along with two other families…" She trailed off, and stared at the floor. She seemed to be mumbling something. "It's not the first time I left Hinamizawa…" She said, a louder than before, but still quietly. It was if she was now talking to herself, rather than her new friends. "I remembered I left once but it was cause of my mother's job, but as soon as we left…bad things began to happen." The air in the room seem to have been filled with something…something nobody could quite understand. It really wasn't awkward silence, but it wasn't welcoming either. Harry and his friends just stared at Rena. They quietly heard the rest of her story…

"You should never leave Hinamizawa, I broke that rule…I broke it again…" Her voice got quieter…it was harder to hear her. But nobody knew if it was best not to discuss this, or continue on. The air had a eerie feeling in it, Rena was not acting herself. The more she mumbled, the more the eeriness grew.

"R-Rena." said Harry, finally deciding to speak out, and stop this. "Is everything alright?"

The three just sat there, while Rena's head hung down. They awaited for her to say something, when she finally looked up. She gave them a smile. "Yes, everything's alright," She said, her cheery voice returning.

Author's Note: End of chapter 1! Quite the long chapter too…well hoped you enjoyed.
