Disclaimer: I don't own anything Naruto.

Summary: What would it be like if Itachi had a twin sister, Koi, who knew the truth about when Itachi supposedly murdered their entire clan? What if he had thought that she had runaway and gone to find her while in fact she was raising Sasuke? When Sasuke finally meets Itachi on one of his missions and comes back with some major injuries, will she decide to tell him the truth or will she keep him in the dark and give Itachi a piece of her mind?

Author's Note: Sorry ahead of time about the time line I haven't read that much of the Naruto series, and I couldn't remember the name of the Hokage before Tsunade. Another sorry for later chapters, there's some pretty graphic scenes. In addition, most of the pairings are undecided as of yet. Though be prepared for some Uchihaest. I also apologize if I totally screw up the Jutsus and Sharingan levels. I'm sorry but I feel since I haven't read that far and don't really know if there is a Sharingan level that can share memories I made up one and it's called the Omoide Sharingan. Oh, and this takes place sometime post-Chunin exam and pre-Sasuke leaving. Again, sorry for my screw ups.

Memories

(dream sequence)

(AN)

Koi and Kisame were walking at a leasurely pace toward the village hidden in the mist. (I'm not sure if that's where Orochimaru's base is actually at, but if it's not bite me.) Halfway there Koi's eyes glazed over as she began consentrating on a conversation with Sasuke.

"Aneue, when did you say you were going on your mission?" Sasuke asked.

"I was originally supposed to go at the end of the month, but I'm on my way over right now why?" Koi asked.

"Because, I did something really stupid," Sasuke said.

"What did you do?" Koi asked.

"I- Ahhhhh! Aneue! Help!" Sasuke called.

"Otōto! Otōto! Sasuke! Sasuke answer me!" Koi called.

Nothing came back to her.

"Kisame-sensei?" Koi asked innocently.

"What?" he asked.

"Could we maybe move a little faster?" Koi asked.

"Why, are you that eager to get some killing done?" he asked with a smirk in her direction.

"You bet," Koi said with a faulse wicked smile.

"Well then, let's go," Kisame said and started moving at break neck speed.

As they entered the village they were surrounded by tons of rain ninja. They slowed to a stop.

"What's your business in mist?" one of them asked.

"We're here on business with Orochimaru," Kisame said.

"Let them pass," the ninja called.

They made their way through the group and ended up stopping outside of Orochimaru's base.

"What business does the Akatsuki have with Lord Orochimaru, if not his death?" asked a mad with glasses and white hair pulled back into a pony tail.

"I'm here to make a trade," Kisame said.

Koi looked at him shocked.

"What exactly are the items in which are being traded?" asked the man.

"Orochimaru has a ring in his possesion that Leader is very much desiring to have returned. I hear that Orochimaru has been meaning to get his hands on Uchiha Koi, so here she is," Kisame said.

"I'm sure Lord Orochimaru would be very happy to accept your offer. Won't you come in?" the man asked as he made a signal.

Ten ninjas came out and tackled Koi to the ground.

"Take her to Lord Orochimaru's quarters," the man called as he led Kisame inside.

"YOU TRAITOR!" Koi called trashing beneath the men that were now pulling her off the ground.

Somehow she ended up being carried by both arms and legs inside thrashing all the way calling out any and all obsinities she could think of. In the middle of her tenth tirade Sasuke came into her veiw and she stilled completely at the sight of him.

"Aneue?" he asked coming closer.

"Otōto?" she asked as he stopped at her side.

"Put her down. I'll take her the rest of the way," he said sternly.

The men mummbled something about how as soon as Orochimaru did something they wouldn't have to deal with listening to Sasuke anymore, but Koi didn't catch it as she was placed on her feet again. The men took off down the hallway to do whatever.

"Otōto, what are you doing here?" Koi asked.

"It's a long story and we don't have that kind of time. All I can say right now is that I need your help," Sasuke said looking scared to death.

"I'd do anything to help you Otōto, just tell me what to do," Koi said.

"You have to get me out of here. I don't care how, but you have to. He . . . he looks at me weird. And earlier . . . he . . . touched me," he said looking repulsed, and started on his way down the hall.

"What do you mean touched you?" Koi asked following closely behind.

"He treats me as though I'm his pet most of the time, but earlier he called me to him and he held me in his lap. Then he wrapped his arms around my waist and tried slipping his hands up my shirt. And he didn't exactly hide the fact that he was really liking me in his lap," he said sounding on the verge of barfing.

"That bastard!" Koi yelled.

"Shhhhh! If he hears you who knows what he'll do," Sasuke said clamping a hand over Koi's mouth.

Koi nodded and Sasuke took his hand from her mouth. As they continued on their way Koi placed a hand on Sasuke's shoulder to hopefully comfort him, even if only slightly. It seemed to work as he wasn't walking nearly as stiffly as he had been earlier.

They arrived at Orochimaru's chambers and they both entered. Koi looked at Sasuke confused, but Sasuke just shook his head signaling that everything would be explained later. They sat there for several minutes before the door opened.

"Ahh, I was wondering if you made it here. Although it looks as though they didn't tie you up as I asked," Orochimaru said.

"I'm sorry sir, I brought her here myself. She seemed to be struggling rather hard against them and only stilled after she heard me. I figured it might be better if I brought her than having your men loose their lives because she simply was upset," Sasuke said from his place in a chair behind Koi.

"Well, this could be fun. I wasn't expecting to have you both in the room together," Orochimaru said moving closer to Koi.

Koi growled and moved herself to hide Sasuke completely behind her.

"Protective older sister, why didn't you mention that Sasuke?" Orochimaru asked.

Koi growled again and cracked her knuckles as Orochimaru stepped closer. She told herself that she wasn't going to make a move until he moved to do something to either of them and he hadn't tried anything yet, he was just talking. She tried convincing herself that he was just talking, but it became harder and harder as his smirk started getting more and more mischieous.

Finally he was right in front of her and she stood her ground even though she wanted to run so badly. He brought his hand up and cupped the side of her face. She didn't react until he began stroking her cheek, that's when she slapped his hand away from her. He looked at her like he was going to kill her and grabbed her wrist catching off guard as he threw her into the wall behind him.

"Now, I'm going to make you watch as I take your little brother," he said advancing on Sasuke.

"Aneue! He-help! Ane-" Sasuke called cut off as Orochimaru claimed his lips.

Sasuke tried pushing against him but he was soon rendered motionless as Orochimaru pressed him back into the chair and wrapped an arm around the back of the chair keeping his arms still and the other around the legs of the chair to keep his legs still.

"Gmfh mfh," Sasuke mummbled against Orochimaru's lips.

Koi growled and jumped toward them. She tore Orochimaru from Sasuke and threw him against the wall before turning to Sasuke. The chair had fallen backward and Sasuke had rolled into the corner hugging his knees to his chest. Orochimaru's movement behind her told her that she had to finish dealing with him before she could worry about Sasuke.

"Possessive too. This is fun. Is little Sasuke the same way with you?" Orochimaru asked.

"Don't think you're going to find out," Koi said grabbing a sword from the wall and running at Orochimaru.

There was nothing he could do to prevent the sword plunging into his chest and then slicing down across his stomach. He just stared shocked into Koi's eyes as he fell to the side. Koi turned around looking toward Sasuke. Sasuke ran toward her and barried his face into her stomach. Koi lifted him and moved him so that he was on her back before turning back to Orochimaru's body, slicing off his head, wrapping it in some cloth, and heading out of the room as fast as she could.

Once she had made it out of Orochimaru's base she could see Kisame walking off into the trees back toward the Akatsuki.

"Hold on tight Sasuke," Koi said and sped up to catch up.

"Kisame!" she yelled.

Kisame turned and smirked at her.

"Oh hey, I completely forgot about you. Sorry about that. Looks like you made it out okay though. Although you have a leech on your back," Kisame said.

Koi came up and puched him in the face and gave him a Chidori kick when he rose again.

"Let me explain. It was all part of the plan," Kisame said.

Koi was relentless in her attacks she just kept throwing punches and kicks his way some were just pure strenght whereas others were laced with Chidori. Finally it looked as though he wasn't going to get up again and Koi took out a few sebon. She took the ring from his pocket and sliced his neck with a sword before tossing said sword away.

"Otōto, do you think you can walk with me back to base?" Koi asked looking at him over her shoulder.

Sasuke nodded and Koi slipped him off her back before throwing Kisame's body over her shoulder and grabbing one of Sasuke's hands.

"If anyone asks, he was killed on our way out. Got it?" Koi asked.

"Yes, Aneue," Sasuke said.

With that Koi led the way back to the Akatsuki base. Upon arriving they were surrounded by Akatsuki members. Koi pulled Sasuke to her chest as they closed in.

"We send you on a mission and you come back with your sensei dead and a straggler," Pain hissed.

Koi growled and whipped her head forward as someone came close. Seeing that it was Itachi she pushed Sasuke into his chest.

"Please take him to a safe place. He needs comfort. I'll meet you after I talk to 'Leader'," Koi said.

"You didn't have to ask me," Itachi said as he walked back inside with Sasuke pressed against his side under his cloak.

"Leader would like to speak with you to see how your mission went," Pain said.

"Lead the way," Koi said emotionlessly.

Pain led the way to 'Leader's' office and slammed the door behind her.

"Ahh, I see you have returned. You seem a little battered, and is that Kisame over your shoulder?" 'Leader' asked.

"He was killed on the way out and I figured you'd like to give him a proper barrial. That is assuming you actually do that," Koi said dropping Kisame's body to the ground.

"That was very kind of you. I'll have you know though that we usually don't do that. At least not while it's tough getting out. But we're getting off subject. Did you finish your mission?" he asked.

"Here's the ring and I brought you proof that I killed that bastard Orochimaru," Koi said dropping Orochimaru's head and the ring on 'Leader's' desk.

"Well done. However, the ring is yours to keep. Also, here's your pack and your very own robe," 'Leader' said handing her the ring, her pack, and the robe.

"Thank you," Koi said with a bow.

"You will call me Leader from now on just like the rest of them. Also I heard that you brought a straggler back with you. May I ask why?" Leader asked.

"I'm sorry Leader. I rescued my little brother from Orochimaru's clutches. I wasn't thinking when I brought him here. If you don't want him here then I can take him back to our home village," Koi offered.

"You can't very well go back into the village," Leader pointed out.

"No, but I can go to the baths around the village. His team usually bathes there at least once a week, and his sensei is there every night. He will be in safe hands if I leave him there," Koi said.

"If his presence becomes a nuesence then I will ask this of you. As it is, he can stay. Assuming you won't want him to be far from you then here. He may wear this until either he becomes too big of a problem or he wishes to return home," Leader said handing her a second robe that is slightly smaller.

"Thank you Leader," Koi said with a bow.

"You are dismissed," Leader said.

Koi bowed again and took off toward Itachi's room. She dropped the robes and her pack in a chair before slipping the ring on her thumb, since it was the only finger it fit on, and climbing into the bed. Itachi lifted his arm that was drapped over Sasuke to allow her to hold them both close. He then drapped it over Koi and they all soon fell asleep.
