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.

"Koi, what can I do for you?" Hokage Tsunade asked.
"I know you're not supposed to tell me, but I would like to know where exactly you sent Team 7 on their mission," Koi asked in false sweetness that always worked to get the Hokage to tell her what she wanted to hear.
Koi looked like Itachi's double except that her hair was knee length. She was dressed in the Junín uniform. She had also followed Itachi into becoming an ANBU.
"You're lucky Shizune isn't here or else I would have a witness. I sent Team 7 to investigate the old ruins of a temple in the Land of Fire. It's about 5 miles to the west from here. If you travel through the night you may be able to catch up to them," Tsunade offered.
"No, I just wanted to know. How long should it take them?" Koi asked.
"They should be back in three days. Longer if they get into trouble," Tsunade said.
"What do you mean if they get into trouble?" Koi asked, the sweetness leaving her voice instantly.
"It's rumored that the Akatsuki have been watching the ruins. I sent Team 7 to try and figure out why the Akatsuki would be so interested in them," Tsunade said simply.
"The Akatsuki! Do you realize who all is in the Akatsuki?" Koi screeched.
"Yes, I do thanks to your spying abilities," Tsunade said not really reacting to the outraged teen.
"Then why in the name of Kami did you send Sasuke and his team out to possibly get smashed by them?" Koi asked angrily.
"I figured that it would give them a little more experience. Besides, Itachi might show up and show your little brother that he shouldn't hold his nose so high in the air if he wants to get anywhere in life," Tsunade explained.
"If you were having problems with that again, then you should have told me; not sent them out on a mission that they most likely won't come back from. If they have sustained enough injuries to land them in the hospital, I'm going to have a long talking to with you," Koi said and took off out of the window.
She went home, changed into her ANBU uniform, and went to sit in one of the trees just inside the village gates. This was her normal routine. She would hear that Team 7 was sent out on a mission, go to Tsunade to find out what it was, then sit in 'her tree', as she called it, to wait for them to return. She never intervened unless they called for backup. However, she was really worried about this mission. It would be the first time that Sasuke had seen Itachi since the massacre. Frankly, that in and of itself was what really scared her. She knew that Itachi had told Sasuke to grow to hate him and one day he would defeat him, after Sasuke had come home to find Itachi standing over their parents pulling the sword from their chest. Sasuke immediately assumed that Itachi had killed everyone, and it worked to Itachi's advantage. Itachi had left that night trying to find her, but she had gone to Sasuke's side after she was sure Itachi was far enough away.
She pulled herself from her thoughts so she could concentrate on the present and know if someone came through the gates.
-Meanwhile-
"Kakashi-sensei, how much further are the ruins?" Naruto asked in a whiny voice.
"If you ask that question one more time I'm going to pin you to a tree and only let you down after we're finished with the mission," Sasuke said in a venomous tone.
"Calm yourself Sasuke. It's only another hour to get there," Kakashi responded.
They traveled the next hour in silence and as promised, they arrived at their destination. They walked into the ruins and started their investigation.
"Someone's coming," Sasuke said suddenly.
Everyone stopped what he or she were doing and tensed as they took up defensive stances and carefully looked around.
"Well, well, well. Looks like we found the source of the disturbance," called a cold emotionless voice.
Everyone turned to the voice and came face to face with its owner.
"Itachi," Sasuke cursed.
Without warning Sasuke charged toward him. Itachi easily dodged the punch, grabbed him by the wrist, and threw him into the opposite wall. Sakura screeched and went to his side. Sasuke simply pulled himself back up and charged again. This time he chose to kick which ended up with him spinning to the ground. Naruto entered the fray and tried a few punches of his own only to have them easily blocked and get punched in the stomach.
"So this is Team 7, the team that defeated Zabuza? He must have been weak, because you're all pathetic," Itachi said coldly.
"Easy to call one pathetic when you yourself are as well," Sasuke said, "You couldn't even find Aneue."
"That is regrettable yes, but you can't even land a hit. That is truly pathetic," Itachi said.
Sasuke charged again and was once again tossed away easily. Naruto threw an assortment of shuriken and kunai that were all easily dodged. Naruto and Sasuke immediately regrouped and came up with an idea.
(Basically, it was the same thing that they did the first time they met Zabuza.) Sasuke threw a shuriken at Itachi who caught it easily and hiding in its shadow was another one that he only had enough time to dodge. The shuriken turned into Naruto who then proceeded to throw a kunai. Surprisingly it hit, however Itachi then turned into a puff of smoke.
Sakura's scream immediately brought all attention to her. Itachi stood behind her holding a kunai to her throat. Kakashi suddenly appeared behind Itachi with a kunai to his back.
"Looks like you have learned, too bad it doesn't matter," Itachi said with a smirk.
"What's that supposed to mean?" Naruto bit out.
"Aw, why'd you have to start the fun without me?" came the voice of Itachi's partner Kisame.
"Go ahead and start your fun," Itachi said not letting any emotion in his voice.
Naruto spun around and moved to attack Kisame, which was a failed attempt that landed him face first on the floor. Itachi simply flung Sakura around into Kakashi and escaped from the kunai in his back. Sasuke took that moment to attack again, actually landing a few hits before finding himself on the ground again.
"You don't have enough hate Otōto. If you had more hate you could beat me," Itachi hissed.
Sasuke sprung up and attacked again. Itachi caught his fist and used it as leverage to throw him into the wall behind him.
"Sasuke!" Sakura screamed and ran to his side.
Sasuke hissed as he pulled himself up with one arm.
"Sasuke, your arm!" Sakura screeched.
"Just pop it back into place. I don't need extra time wasted by you screeching," Sasuke said sternly.
"A-are you sure?" she asked.
"Just do it," Sasuke said squeezing his eyes shut.
"Alright," she said.
She placed one hand on his back and the other on his arm. She quickly shoved up and popped his arm back in place as he grunted and bit his lip in pain.
"Are you alright?" she asked.
"I'm fine. Thanks Sakura," he said and went to attack Itachi again.
This time he threw to handfuls of kunai and shuriken when he attacked. This caused Itachi to move in the way of Sasuke's attack. Sasuke proceeded to land another ten hits before he was thrown to the floor again.
Kakashi decided that he had seen enough and attempted to help. However, Naruto suddenly screamed out in pain and he diverted his attention from Itachi to Kisame.
Kisame had, thrown Naruto into a wall, pulled out his sword, and slashed Naruto's arm. Kakashi came from behind and landed a variety of hits before punching hard enough to send Kisame into a wall. He went over to Naruto to see how bad the wound was.
"Naruto, take Sakura with you back to the village and call for backup. If possible get Koi," Kakashi said in an undertone before turning to Kisame who had just gotten back up.
"Yes, Kakashi-sensei. You can count on me," Naruto said and quickly found Sakura.
Without a word, he grabbed her arm with his uninjured one and sprinted to the exit.
"Naruto! Where are we going?" Sakura asked finally being able to pull her arm away.
"Kakashi-sensei, told me to take you with me back to the village to call for backup," Naruto said.
"Why me?" she asked.
"Probably because you were the only one not fighting someone. Besides, I'd probably pass out before I got there anyway," Naruto said his voice taking on a tired tone as they continued on at top speed.
"Why?" Sakura asked stopping.
"I got hit pretty badly with that shark guy's sword," Naruto said stopping to show her his arm.
"Naruto! We have to get you back now!" Sakura screeched pulling Naruto by his uninjured arm toward the village as fast as her legs would carry her.
-Back at the village-
Koi was just getting out of her tree when Naruto and Sakura ran through the gates. Not thinking at all, she ran to them.
"What happened," she asked in an emotionless voice with slight issues as she saw Naruto's injured arm.
"Two Akatsuki members turned up at the ruins 5 miles west," Sakura said.
"Which two?" Koi asked quickly.
"Itachi and that shark guy," Naruto said looking light headed.
"Can you walk?" Koi asked.
"Yeah, I'm fine," Naruto said proceeding to take one step before losing balance, and would have hit the ground had Koi not intervened.
"I'm assuming you can't lift him?" Koi asked Sakura.
"No," she sighed.
"Well, then follow me to the hospital. At the very least they should check you over," Koi said lifting Naruto and jumping off to the hospital.
With that, she left the village at top speed. She made it there in an hour. She could hear fighting inside and prayed to anyone who would listen that Sasuke was okay. She walked in and immediately had Kakashi and Kisame's fight in her face.
She quickly knocked him out with a rather hard elbow to the back of his head. Then looked Kakashi over, seeing that he had just a few scrapes she looked to Itachi and Sasuke. What she saw made her blood boil.
Itachi had been relentlessly punching Sasuke until he passed out and then threw him into a wall. Also somewhere along the line he had managed to land some shuriken and kunai, because Sasuke was bleeding from multiple wounds.
Koi raced to his side and looked closer at the wounds. She saw that most of them were rather deep and could tell that several of his ribs were cracked, and with the force that Itachi threw him into the wall, he might have a concussion. She stood up with Sasuke in her arms and went to Kakashi.
"Take him back to the village, if they ask you where I'm at tell them I'm dealing with the Akatsuki members that attacked you," Koi said icily.
Kakashi nodded and quickly left, wanting to get as far from a very pissed off Koi as he could get. Koi ripped her mask off and stashed it in a random pocket.
"Itachi you bastard!" Koi screamed and turned around throwing shuriken and kunai to distract him as she raced in and punched and kicked any part of him she could reach.
Luckily all of her attacks landed. She kept going at him until she couldn't keep up her steam anymore.
After some shaky breaths Itachi managed to ask, "What's the matter, Koi? Did I do something to upset you?"
"I know you're not that thick headed Itachi! Quit faking and stand up for what you did wrong!" Koi yelled.
"So I beat up Sasuke. It was only to give him the incentive to grow stronger, because he obviously hasn't," Itachi said coldly.
"You're wrong! He has gotten stronger! You're just too bull headed to see it!" Koi said, throwing a punch at his face and landed it.
"Obviously you have gotten stronger. Your anger and hate have taught you well," Itachi said.
"Wrong again, Itachi. My anger and hate only make my attacks wilder. It's my protectiveness that has made me stronger," Koi said and managed to get behind Itachi with and kunai to his neck.
"Impressive, however, I can feel your anger rolling off of you," Itachi said.
"This isn't anger," Koi said activating her Sharingan, "This is anger!"
She attacked wildly and fast. She only landed half of the hits she threw this time around. Itachi was even able to land a few, the last one ended with her doubled over.
"See, what I mean? Anger makes you sloppy, love and protectiveness make you stronger," Koi said cooling herself before attacking again.
She threw a random assortment of shuriken and kunai before barreling in and landing six punches and four kicks before backing away as Itachi threw a punch. She looked up to his eyes and noticed that his Sharingan was activated. She fought a laugh as he started to challenge her Sharingan. His challenge didn't go any further than Mangeko and she fought another laugh.
"That's all you got?" she questioned.
"That's as high as it goes, is it not?" he asked.
"Wrong! It can go higher, but you have to be able to attach yourself to others. You have to actually be able to let your feelings through the mask. In addition, there's more than one way to get the Mangeko Sharingan. I didn't kill my best friend, I didn't kill anyone," Koi said seriously.
"How?" Itachi asked.
"You'll never find out as long as you remain a member of the Akatsuki, and treat Sasuke as bad as you do," Koi said sternly.
"You do realize how dangerous it is to leave the Akatsuki don't you?" Itachi asked.
"Nope, but I have a feeling I'm going to find out, and it won't be a second hand experience. Just promise me one thing Itachi," Koi begged.
"Hmm?" Itachi hummed.
"If I get sent on another spy on the Akatsuki mission, I want you to help me actually get in. Just so that we can leave together," Koi said brightly.
"You're insane!" Itachi yelled.
"Yup but that's me," Koi said and then jumped behind Itachi and quickly dealt an elbow to the spot where the head meets the neck, "Sweet dreams."
She drug Kisame over to Itachi and tied their hands together behind their backs then tied their feet together. It was a rather amusing sight if you asked her.
She then ran as fast as her feet could carry her back to the village. She went straight to the front desk to find Sasuke's room, and got in with no problems. She sat in the chair beside Sasuke's bed after doing a quick scanning Jutsu, and finding that all was in order. Boy was Tsunade in for a long talking to.
