Ok, people of the Naruto fandom. At this time, I am beginning a new story while in the middle of writer's block for She's Still Mine. Feel free to also read that story (which is the sequel to Itachi's Pet) and give me inspiration for the next chapter.

This is a story of a speculation of mine: if two twins are separated at birth, what happens in the life of the two? What happens if they meet and do not know they are twins? This here story is the answer to these questions.

Important ages:

Itachi: 16

Yoruichi: 16

Sasuke: 12

Sakura: 12

Naruto: 12

Kimiko: 12

Disclaimer: I do not own Naruto. Only Yoruichi and KimikoYuhi.

Chapter one: The First Day

~Sixteen Years Ago~

Third Person POV

New mother Uchiha Mikoto smiled affectionately as she laid baby Itachi in the crib next to his twin sister. The two couldn't stand to go through the night without the other lying with them. She loved how they were already close.

"Mikoto." The woman turned around to see her husband, Uchiha Fugaku. "You should get some rest now while they're sleeping."

"I'm coming. Just give me a moment." She kissed her fingertips and pressed them to the baby's cheeks in turn. Reluctantly, she then left the room.

Three hours later, the Uchiha estate was silently broken into. And the only thing taken was a baby girl.

~Present~

Itachi POV

"Next on the agenda, we are expecting two new students to join us today." A picture of two girls appeared on the overhead.

Both girls had matching black hair and flawless facial features with hour glass bodies. The smaller of the two had her shoulder length hair tied up in a high ponytail, and her blue eyes sparkled at the camera with her smile. She had a dimple on her left cheek, and she was wearing a pink mid thigh dress. The taller girl had her waist length hair flowing down her back, and her eyes that were as dark as mine stared blankly at the camera. She wore a black and red tank top with black tights and dark red mini skirt.

"Yoruichi and KimikoYuhi are sisters that are transferring from Erito Academy. Who wants to give them the tour?"

The secretary of the student council, Haruno Sakura, was met with silence. No one wanted to spend their day basically babysitting two girls. Next to me, my brother, Sasuke, sighed.

"I'll do it. Since nobody else seems to want to." I patted my younger brother's shoulder as the pink haired girl handed him a brown envelope.

"If no one else has anything to add…." I glanced around the silent room. "This meeting is now adjourned."

"Hai." The members of the student council stood up and left the room. I walked alongside my little brother.

"That was brave of you, otouto. I'm proud of you for stepping up to the plate like this." He snorted.

"As the vice president of the student council, I am expected to accept any job the other representatives do not want to."

"You're reciting me." He gave a short laugh, and I smiled softly. My younger brother is the only person in the world that can make me soften up like this. I guess it's a sibling thing.

"I have to go. The Yuhi's will be here soon."

"Good luck, otouto." He nodded and walked off to the entrance of the academy. Now bored and alone, I walked to my first class to await the beginning of the school day.

Later at lunchtime, I walked through the line to get my lunch. Next to me, one of my friends, explosives fanatic artist Deidara, was talking my ear off. I had begun to tune him out five minutes ago, but he just won't stop.

"…understand right? Art should be a beauty that lasts only a single instant before…. What's Kisame doing?"

I followed the blonde's line of sight and sighed softly. My blue haired friend was making his way to the taller of the two new girls. She was sitting alone in the center of the cafeteria, reading a book.

The teen male stood over the girl and began talking to her. I could tell by smirk that he was taunting her and making erotic suggestions to her, but she never so much as twitched. After a minute of this, she lifted her head to calmly ask him something. Apparently, he did not like that, because he slammed his hand on her shoulder and spoke again.

"Itachi," Deidara started.

"On it." I took a step in their direction.

But then I froze as she slammed Kisame into the floor and held him down with her foot on his chest. The cafeteria went silent as she leaned over him, her hair falling over both of them.

"You know, I really don't like having to resort to violence. It's too messy." Despite her soft tone of voice, I could hear in the silent room the firm bite in her words as she spoke.

"Get off of…." He grunted as she pressed her heel further down on his chest.

"I'm still talking to you. Don't interrupt: it's rude. You made so many little comments that I could have you arrested for. But I was going to let it slide because there is no need to get someone who doesn't know me and I don't him in trouble for something as petty as that dirty little mouth of his. However, I think I should make an example out of you now. Don't you agree?" It was then that I decided to walk closer to them.

"Although I do not agree with Kisame's actions, I cannot allow you to retaliate in that manner, Miss Yuhi," I told her.

"Unless you are planning on making me stop, I suggest you take your soft spoken mannerisms, shove it, and beat it. I am done with the boys in this academy. They act like dogs at the first sight of a pretty new face."

"I understand that, but…."

"Do you truly? Have you ever had to look over your shoulder to make sure no one touched your butt?"

"Well…." Do fan girls touching my hair count?

"Have you ever had to explain to your principal why it is that a male student will never be able to have sex again without major surgery?"

"Major?" I'm beginning to understand why Erito Academy transferred her here.

"I didn't think so. Now, I hate having to repeat myself, but I will make an exception just for you because you are so gentlemanly. Unless you are planning on making me stop, I suggest you take your soft spoken mannerisms, shove it, and beat it."

I almost did. But, as the student body president, I can't allow her to continue.

…

Though I would rather not be in Kisame's position if I attempt to stop her.

"Now, this is what's going to happen at this time, since I am being nice. I am going to move my foot off of your chest. Then you will leave. Ok?"

"H… hai." She lifted her foot and sat back down in her seat, picking her book up. I helped Kisame to his feet and silently led him to our lunch table. "Itachi…." I held my hand up to stop him.

"We'll talk about this later."

~Fifth Period~

"Class, today we have a new student joining us for the remainder of the year. Please make her feel welcome as she introduces herself to us," our teacher, Iruka, stated. I raised an eyebrow: it was the girl from before.

"First of all, do not feel like you need to make me feel anything. Yoruichi Yuhi needs no soft, bittersweet words. I do not tolerate disrespect. You touch me or my sister inappropriately, and I will need to transfer again. Do I make myself clear?"

"Crystal," some of the more easily frightened classmates stammered.

"Why don't you take a seat next to Itachi?"

"Hai." I watched the girl as she sat next to me. Her eyes were the exact same shade as mine, and her hair was visibly as soft and smooth.

"Miss Yuhi, you arrived just in time because Itachi needed a partner." We glanced at each other then back to the front at Iruka.

"A partner for what?" we asked together. He smiled.
