A/N: This story will be updated approx. every 2 weeks. This is because I'm very busy with school work. I always have progress notices/updates posted on my profile, so check it out. Please review and I hope you enjoy.

Chapter 1: An Avenger's Eyes

The female figure dashed gracefully among the tree branches. It has been about a year and a half since she had seen her father. She had been sent to a different hideout, where she had to overlook the research taking place there. Now, she had to deliver the results found to her father and luckily she didn't have to go back to that wretched place. The number of people held in the hideout was unbelievable. All of them with no hope, for they knew that the chances of living through an experiment were low. She wished she could save them, but she is only one person. Sure she could probably take out the rest of the guards, but afterwards she'd have to face her father for her disobedience. She could never disobey him; after all he has provided so much for her.

The teenage girl looked below the trees to see a hooded figure below. She jumped down, stopping just in front of him. "Yo! Buto-chan!" She said smiling cheerfully.

The figure took down his hood. "I see you're doing well, Nayami-san."

"Ka-bu-to…why are you so formal? I've known you since forever! If you can't call me Nayami-chan or Yami-chan or even just Nayami, then call me Nayami-sama. At least that would make me laugh," She said pouting with both arms folded.

"Hai, Nayami-sama."

She stared at him. "For some reason that wasn't as funny as I thought it would be."

"Come on now, we really should get going." He turned and began to walk away. Nayami followed.

"Kabuto, aren't you gonna say hi to Niko?" She asked, holding up her stuffed cat. It had green eyes, black fur, and a red ribbon tied around its neck.

"Hi, Niko."

"Buto-chan! You haven't seen her for a year and a half and all you have to say is 'hi'?"

"Isn't that what I basically said to you?" he asked, but she ignored the question.

"Look, now she's doing a puppy dog pout…"

"Heh, how's that even possible? One Niko is a stuffed cat, it can't do anything. Two Niko is a cat isn't she? How can it make a puppy dog pout when it's a cat?"

"Well…….Uhhhh……., we're human and we still say we make a puppy dog face, so how is Niko-chan's situation any different? Is it just because she's a cat? That discriminating! Stop the discrimination!"

Kabuto couldn't hold back a smile, okay it was a rather small smile, but a smile none the less. "I won't lie Nayami-san. I did miss you a little."

Nayami put her hands to her cheeks. "Stop it Buto-chan! You're making me blush." Kabuto rolled his eyes. Nayami put her hands behind her head as she walked. "Ahhh, I can't wait to see Sakon and Ukon."

Kabuto's eyes darted to her. "Why would you need to see them for?"

"Because…they're my friends. And I want to shove my boobs in their faces!"

"Excuse me?"

"They used to tease me about my flat chest all the time. But now, with these, I'll make their noses bleed to death."

"You're kidding."

"You better believe me when I say I'm not! Speaking of blood, that reminds me of the time when Sakon and Ukon bungee jumped of a tree using one of Kidomaru's webs, turned out that the string was too long. Boy did they hit the ground hard!" And Nayami continued to talk about the fun times she had with Sakon and Ukon. Kabuto nodded and chuckled at appropriate parts, until they arrived at the hideout. He suddenly wished that it had been a little farther away. He didn't want to see Nayami's reaction when she found out that her two best friends were dead.

/(*)\

Kabuto lead Nayami to Orochimaru's room, but stopped in front of the door. "I think he's seeing someone right now," Kabuto started, but Nayami barged in anyways.

"Daddy! I'm home!" Naya shouted and jumped onto Orochimaru's bed, where he was laying. She began nuzzling his neck like a cat. "I missed you Daddy."

Orochimaru patted her on the head. "Yami-chan, you're as cheerful as always. I was beginning to miss that smile of yours." Nayami gave him a toothy grin.

"I'm a lot stronger than I was before! I've been training every day!"

Orochimaru chuckled. "Are you strong enough to handle an Uchiha?"

She tilted her head to one side. "Probably not, they're like….really strong ya know? But I would definitely take up the challenge 100%!"

"Well, he's standing right there." Orochimaru pointed out the boy with raven-color hair.

Nayami leapt off the bed and was in front of him in a second. She held out a hand. "I'm Nayami! What's your name?"

Sasuke stared at this girl standing in front of him. On the outside his face was calm and full of composure, but on the inside he was thinking "Dude, what the fuck? Is this really Orochimaru's daughter? How come she was never mentioned before? They look nothing alike." He looked from Orochimaru to Nayami. She had pale skin, not as pale as Orochimaru's, but probably about the same skin tone as himself. Her hair was blond and very long, it stopped above her hips. She kept it up in a pony tail and bangs partially covered her bright cerulean eyes. As far as he could tell, she looked nothing like Orochimaru. Except for her eyes, but instead of being snake-like, they were more…cat-like?

Sasuke felt something poking his face. "What's wrong with your new toy Daddy? Did you break him or somethin'?

Orochimaru chuckled. "He's not much of a talker."

"Oh…How boring!" Nayami yawned. "I'm kinda tired….I know! I'll go see Sakon and Ukon, before I take a nap!"

"How are you so energetic when you just said you were tired?" Sasuke thought to himself. "Who are those people anyway? I don't think I've ever seen them around here before…"

"You can't see them," Kabuto said quickly, glancing over at Orochimaru.

"Why? Are they on some kind of mission?"

"Nayami, they're dead." Orochimaru said plain and simple.

Nayami blinked and smiled. "No, you're…you're lying!"

"They died on a mission."

Nayami frowned. "What mission would that be?"

"Bringing Sasuke to me." Nayami looked at Kabuto. Kabuto nodded and then she looked from Sasuke to Orochimaru and back.

"You mean…they died…because they were bringing this guy to you?" Nayami asked slowly, all cheerfulness was gone from her voice. Orochimaru nodded. She closed her eyes to keep tears from falling. "No! You liar! They died because of him!?" She pointed at Sasuke.

"They knew the risks they were taking…" Kabuto started, he had sensed Nayami's growing anger and was trying to calm her down, but Nayami was already running towards Sasuke. Sasuke moved back, but didn't notice that she had moved behind him. She punched him hard in the back and towards the wall. He landed sideways, on his feet.

He watched her change, literally, in front of him. The cheerful blue eyes were replaced with a killer's intent. They were the eyes of an avenger. Her teeth, now sharp fangs, her ears disappeared and were replaced with a cat's and a cat tail grew out from behind. Her hands were now claws and were now attempting to take a chunk of Sasuke's flesh from his body. If Sasuke ever tried to imagine a girl with cat ears and a tail, he would think of a very annoying girl that did nothing but read manga, not some blood thirsty monster.

He dodged all of her attacks, but was unsure if he should attack her or not. She was Orochimaru's daughter after all; it might not be a good idea. But then she was attacking him, so it's technically defense. Just as Sasuke was about to draw out his sword, Nayami's right claw dug into his shoulder.

"NAYAMI!" Orochimaru finally shouted. She withdrew her claw from Sasuke's shoulder and practically flew at Orochimaru. She began shaking him wildly. "Why!? Why did you let them die!? Why did they have to die!? Why did they have to give their lives for that bastard!?" Nayami yelled, tears of anger and sorrow flowing from her eyes. Her claws turned back into hands, the cat ears and tail disappeared, and her eyes grew soft. "Why Daddy? Why?" She began to cry.

Orochimaru patted her on the head, but from his expression, Sasuke could tell that he was very tired and pissed off with Nayami's change of behavior. Sasuke put a hand to his shoulder the one Nayami attacked. He couldn't believe that she actually managed to land a hit on him. He looked up to see that Nayami was still crying in Orochimaru's lap and he must say he has never seen a stranger sight. Orochimaru whispered something in her ear that made her crying turn into sniffles. She nodded and wiped her eyes. "Really?"

"Of course, in due time…"

Nayami nodded and got off Orochimaru. "I'm going to my room now. Please don't bother me unless it's very important."

She left the room and Orochimaru turned his attention back to Sasuke. "Well, what do you think of her Sasuke-kun?"

"She's not going anywhere with me. She'd only be in the way."

"That's what you think, but you don't know her as well as I. She's actually very useful and very bright. I'm sure her anger towards you will wear off soon. Kabuto, go explain to her who actually killed Sakon and Ukon."

"Do you really think that will change anything?" Sasuke asked as Kabuto left the room to follow Orochimaru's orders.

"No, she'll still be angry, but it'd be better if her anger was directed at something else."
