A/N: So generally I'm formulating ideas and writing for Hetalia fanfiction, but I recently began watching Ouran High School Host Club. I've only watched the anime, and I don't plan on reading the manga because I know my OTPs don't happen.

That being said, I ran away to fanfiction to read what I wanted to. And now I'm writing what I want to.

This idea has been flitting in my mind almost as much as an Ouran x Hetalia crossover (where the Hitachiin meet the Italy brothers who would also be identical twins in that story...) idea I've had. I've seen this concept done before, but I didn't like how it was done, simply put. Went way too fast and a bit confusing, so I'm spicing the idea up a bit and writing it in my own way. Because I'm boss like that.

WARNINGS FIRST! This is a YAOI story. It is a HITACHIINCEST YAOI story. If you don't like the pairings HIKARUxKAORU, you're in the wrong place so just back on up man.

Pairings: HikaKao, KyoTama, MoriHani

Summary: By some twist in fate, younger twins are given strange powers at birth. Because of this, laws all over the world have declared that all younger twins must die.

"I can't... I can't let them take him...! Look at him, so small... so precious... he's not harmful at all! I-I can't... I can't... Please don't make me... don't call them... please..."

"I won't, Suzuha... I can't. He's our son..." Pause. "I'll take him tonight. To America. I'll take the private jet, no one will ever know. He can grow up with a loving family there."

"Y-yes... that's best... He can live th-there without fear of d-death...!"

"I'll go get ready."

"Alright... Thank you... I-I... Thank you..."

After reaching America, the young twin's father searched for someone worthy of watching his child. It was June 11th when he met a young, wealthy woman who couldn't have any children of her own. She mourned over this fact, and they spoke for a while about children, eventually leading to the topic of twins. He found out her opinions on the matter... and a decision was made.

A few days later, the young woman heard the doorbell ring. When she went to answer it, there was no one there. The only sign that anyone had been there was a basket with a bundled-up child and a brief note.

Please take care of our son. He was born in Japan on 9 June, but if he stayed he would die. He's a twin, a younger twin. I promise I'll never come looking for him, I'll never try and get him back. All I ask is you keep the name we chose for him; Kaoru. Please take care of him.

-A Grieving Mother and Father

She did.

Sixteen years flew past before Susannah Greys knew it. Her little boy, Kaoru Greys, had grown into a fine young man. His control over his powers was phenomonal, and his grades in school were excellent... except maybe for science, he was just barely holding a B average. He was trying, though, that was what counted. Everything was fine, everything was simple. Their family was solid and tight; nothing came between them.

Kaoru, however, couldn't forget the fact that he had a twin. He'd known for years, ever since his parents explained why he had strange powers and where he actually came from when he was seven or eight. The problem was, Kaoru wanted to know who his elder twin was, what he was like, if he was happy...

So one day, when he approached his mother, he said very straightforward; "I want to go to Japan and find my brother."

Susannah nearly dropped the pan of lasagna she was holding and turned to look at her son, eyes wide. "What? But it's so dangerous, Kaoru!"

"I know. But I need to know if he's happy where he is," Kaoru whined, looking at his mother with glden-hazel puppy-eyes. "I don't want to talk to him or befriend him or anything. I just want to know he's alright and happy."

"Kaoru, if you went to Japan and were found out, you'd be killed, you know that," she protested desperately, wanting him to be safe.

"I just won't be found out then."

"How will you manage that when you'd have a doppleganger walking around?"

"There's no guarantee we're identical," Kaoru pointed out.

"You'll at least look similar," his mother shot back. "It's too dangerous. I won't allow it."

"Mom! I'll dye my hair and wear colour contacts, just please, let me go. I need to know!" Kaoru was practically begging. "I know Japanese and if I play my cards right, no one will figure it out!"

Susannah watched her son for several silent seconds before sighing and giving in. She couldn't resist those beautiful begging eyes. "Fine. But you have to promise me something."

"What is it?"

"You'll come straight home after satisfying your curiosity."

"Of course."

"And if you're ever discovered; run. Run as fast as you can. Don't ever unpack your bags, have them always ready to go. Don't look back, just grab your stuff and run to the nearest airport. If there's security there, you know what to do."

Kaoru nodded firmly in understanding, then a wide smile broke out. "Thank you, Mom."

"Don't thank me quite yet," she started, but she smiled slightly back. "You don't know where he is or what his name is. And you still have to attend school."

"I know. I can attend school on weekdays and search on weekends." He smiled at his mom. "Just don't put me in a school full of idiots, please."

Hikaru lived a normal life. Well, normal for a child of the aristocracy.

He hardly saw his parents, but that was normal for aristocracy. All he really had were various servants and random people from school who were tolerable to be around, plus his few friends from the Host Club. The rich boy would never admit he was lonely, though.

Hikaru Hitachiin had always felt like something was missing, something obvious that he didn't see. From the time he was able to walk, able to talk, all the way up to high school, he felt as if someone was supposed to be there with him, sharing the moment. But no one was. He was alone.

Still he grinned and played pranks and joked around with Tamaki and Haruhi, two of his friends from the Club. He flirted with girls and entertained his guests. He did his school work and dreamed and planned for the future. Nothing would hint to anyone outside that he was completely and utterly alone.

As he lay on a bed much too large for one person, much too empty for him alone, he stared at the ceiling and simply thought. There wasn't really much he could do at midnight. So he thought, something he truthfully avoided doing during the day.

Everything felt empty, from his insides- he'd never say something as sappy as "his heart"- his bed, his room, his house, his school, the whole of Japan. Something had been wrong his entire life, something he couldn't figure out. Something he'd never asked his distant parents about. The one time he tried, his mother had broke down crying.

He never asked again after that, deciding to try and fit the puzzle together on his own.

So far, it was still in a thousand divided pieces, the picture obscured.

... Tomorrow's the first day of second year, he thought to himself in amazement. It'll be the one year mark since we all met Haruhi. I wonder if... something big will happen tomorrow. Something like meeting someone like Haruhi again. Not a commoner, just a... a new person. An interesting person. Someone who can brighten this lonely world...

"What am I thinking?" He asked himself aloud, sitting up and hitting his palm against his forehead. "I sound like a poet or something. Ugh, literature..."

He fell back on his bed and turned over. He felt cold, but he was used to it after sixteen years laying alone.

The boy sighed heavily and forced his eyes closed, clearing his mind. Eventually he fell into a restless sleep that would only be disturbed by the alarm several hours later.

Little did he know what was in store for him the next day, and many days after that.

-I thought about ending it here but that's too short for my taste!-

Kaoru took a deep breath. It was the first day of class, and he couldn't let anyone suspect him at all. He glanced at himself in the mirror. His hair was black, carefully dyed so none of his light red actually showed through, and his eyes were a deep chocolate brown thanks to the contacts. They didn't look nearly as lovely as his actual golden-hazel, but if there was a chance he and his twin were identical, he needed to cover them up.

With a firm nod, Kaoru grabbed his schoolbag and headed out of his apartment with confidence. He couldn't help but wonder why his mother just had to enroll him in Ouran Academy of all places. Sure it was a great school, but it was full of rich kids. Stuck-up, nosy, detached-from-reality rich kids.

He walked up to the school gates and into the building. The red-turned-black haired boy glanced around. He honestly had no idea where he was supposed to be going...

A boy passed by. "Excuse me!" Kaoru called, getting his attention. The brunette turned around curiously, and Kaoru quickly realized that this was a girl in a boy's uniform. He brushed that off, deciding there must be a reason. "Can you tell me where class 2-A is?"

"Oh, that's my class," the student said with a smile. Kaoru had a feeling people often mistook this student for a boy; her face and voice were pretty gender-neutral. "Just follow me."

Kaoru did so, hoping this wasn't someone just trying to trick him.

"I'm Haruhi Fujioka," the girl, Haruhi, said with a smile.

"I'm Kaoru Greys," Kaoru told her, smiling back. "I just got to Japan three days ago, so I don't really know my way around."

"I'd show you after school, but I have club activities. Do you plan to join any clubs?" she asked, looking at him. Kaoru simply shook his head. "Why not?"

"I don't have time," Kaoru answered with a shrug. "I mean, I suppose I do, I'm just not really here for stuff like that."

"Ha, that was how I felt when I first came here," Haruhi commented with a little laugh that was definitely feminine. "Some people changed my mind. Maybe some will change yours, too."

"I doubt it..." They stopped outside a classroom labeled "2-A". "Here we are."

The moment Kaoru walked in, he saw him. The boy was like a perfect mirror image of what Kaoru actually looked like, only his hair was messy and spiky instead of straight like Kaoru's. However, the hair colour was that light red, and his eyes were those golden-hazel.

Great, leave it to my luck to get put me in the same class as the person I was looking for. I can't go home yet, it'll look suspicious...

Kaoru knew better than to stare at people so he only watched for a few milliseconds before turning to look at someone else, making sure his calculative gaze remained just as long as on his undoubted twin.

"Kaoru Grey, right?" The teacher asked him, and he nodded. "Your seat is by the window, next to Fujioka."

"Thank you," he nodded and walked to his desk. Immediately he looked out the window.

He had not wanted to be in a class with his secret brother.

Hikaru noticed the black-haired boy immediately. The boy's gaze swept over the class, briefly analyzing everyone, which honestly made Hikaru a bit uncomfortable, but he chose not to show it.

He barely heard the teacher ask, "Kaoru Grey, right?" The Hitachiin boy watched from his peripheral as the boy took the desk on the other side of Haruhi. The boy, Kaoru, immediately turned to look out the window. Hikaru wondered why. But he didn't speak.

"Hey Kaoru, where exactly are you from anyway?" Haruhi suddenly asked the boy, who seemed a bit surprised she was talking to him but didn't react to the informal address. Hikaru decided they had come in together because they were talking on the way there.

"Oh, well, I was raised in America," Kaoru told her with a shrug.

"America, huh? Is it nice there?"

"Depends on where you go," he answered with a small smile. "Too-big cities and too-small towns are generally not very good places to be."

"Why did you move to Japan?"

"I didn't," he answered simply, and Haruhi looked as confused as Hikaru felt. Hikaru wasn't afraid to admit he was listening to this conversation very obviously; he was looking at them and leaning on his desk. "I told my mother I wanted to come to Japan this year. And before you ask, my mother didn't come. She and Father are still at home taking care of business there. I'll go back after the school-year is done."

"Seems like a waste to me to spend so much money to come to Japan, and Puran, for only a year," Hikaru lazily said without even thinking. He was looking at Kaoru's face. That face looked so familiar.

If it wasn't for the hair and eyes, Hikaru would think he was looking in a mirror. He looks a lot like me. Maybe our families are related.

"I'm just here for the culture," Kaoru said with a shrug. "One year is worth it to someone like me."

Before Hikaru or Haruhi could respond, the teacher called the class to order.

It was after school, and Kaoru decided he'd take a look around the school.

He should have known by the whispering and giggling girls to avoid Music Room 3. Seriously. He should have known. But he still opened that door.

He blinked in surprise as he found a group of pretty-boys and Haruhi- and Hikaru, he noted- standing around a chair with a blonde sitting comfortably in it.

"Welcome~" the group said in unison. Kaoru didn't react, he simply stared and blinked at them. There was pure silence between them before Haruhi said, "Hi, Kaoru. I wasn't expecting to see you here."

"I wasn't expecting to see anyone here," Kaoru replied. "I, uh, just looking around. I'll go now." He started to back out the door; he knew whenever rose petals flew out of a room filled with shining light and a bunch of pretty-boys, it was time to run the hell away.

But suddenly something caught onto his arm, and he looked down. There was a short, blonde boy there with tears in his eyes.

"But won't you stay for cake?" he asked cutely, his eyes sparkling with the unshed tears.

"I, uh, I'm sorry, but I have to go-"

"Ah c'mon, Greys, live a little," Hikaru smirked, crossing his arms at the obviously uncomfortable Japanese-American.

"But I-"

"Excusez-moi, but do you know Haruhi and Hikaru?" the blonde in the chair asked with a charming smile and half-lidded eyes.

"We're in the same class. Excu-"

"Then you can be our guest! We don't usually host boys but you're-"

"I'm not-"

"Excuse me, are you-"

"Have cake with me!"

"Mitsukuni-"

Neither Kaoru nor Haruhi- nor Hikaru for that matter- understood why suddenly almost everyone was crowding Kaoru. They all seemed determined to get him to stay, except one of them seemed determined to pry the childlike blonde boy off of the confused Japanese-American instead. Another black-haired boy stood off to the side and simply wrote in his notebook after his own question was interrupted by the childlike blonde boy, but he was still blocking the boy in.

"H-Hey, can't you please stop!" Kaoru tried to push his way out of the crowding group. "I'm completely uncomfortable here...!"

Haruhi suddenly pulled the blonde leader out of the way. Unfortunately, Kaoru had been shoving against him trying to escape, and he went flying...

Right into a small red oak-wood table with an antique china tea set sitting on it.

In the few seconds between the cups falling and the cups hitting the ground, Kaoru thought, Oh no! Mom will be pissed if I end up in debt! She'll tell me to pay it off myself and I'll be stuck here! I can avoid it by using my power but then they'll know I'm a twin and could call the authorities, but staying increases the chances of them finding out, what do I do, what do I-

Unfortunately luck just wasn't on his side that day. Before he could finish his panicked thoughts, the tea-set hit the ground and shattered into millions of pieces.
