Onyx and Ivory

"Here's your mission scroll."

Itachi took the scroll from his superiors' hands as he nodded respectfully. Hoshiko's gaze cut over to the scroll in his hands; trying to see if there was anything exciting on the outside for her to see.

The two teens stood stoically in the ANBU headquarters office, facing their hawk-masked superior. He was a tall man, wearing a dark cloak and spikey black hair; the interesting thing about this man was that no one had ever seen his face. The only person who had ever seen his face was the Hokage, he never revealed his name or what he looked like to anyone; he could pass you on the street and you would be none the wiser. The name he went by was Taka, homage to his mask.

Itachi opened up the scroll and read over the content quickly, his dark eyes scanning over the parchment. Hoshiko was trying not to let her excitement through, she was finally getting her first ANBU mission, and it was with Itachi no less! She must have finally done something right in her life to be rewarded on going on a high-risk mission with her closest friend.

Itachi handed her the scroll with finesse as her silvery eyes read over the words. When she had finished, she looked up, staring into the pupil less eyes of her superior.

"You two have been chosen for your stealth abilities," Taka stated to the both of them.

"I understand," Itachi replied formally. Hoshiko inclined her head to look at him; he was so much different now then almost an hour ago when she had been teasing him at the training ground. He was poised, ready for battle; his eyes were set in hard determination as his fists were clenched at his side.

"You are to depart in the morning, I expect nothing but the best from you two," he said as Taka disappeared in a puff of smoke.

Once Hoshiko was certain that he was gone she let out a frustrated sigh and waved the scroll in the air, "What the hell do you call this?" She growled as Itachi turned to her. "A missing persons case? Come on! This is work for Chuunin's or Jounin, not us!"

"If you read the report, it states that the Hokage sent a Chuunin team to try and find the perpetrator but they came up with nothing," Itachi told her with an exasperated sigh. Hoshiko rolled her eyes and read over the scroll again.

"So, a bunch of people have gone missing over the past few months and no one has been able to find anything about it? Why do we get stuck with the shit jobs?"

Itachi wanted to scold her on her current attitude, but that would cause more hassle for himself and after this afternoon, he really didn't need Hoshiko's whining voice in his ears anymore then necessary.

"Because the age of the missing people fit our description," he said with a sigh. "Did you even read the scroll?" He asked, his tone was more of a hiss now.

"I may have missed a few parts."

"A few?" Itachi asked with a brow raised.

Hoshiko felt her cheeks heat up as she glued her eyes to the parchment and read thoroughly this time.

As of today, fifteen children between the ages of ten and eighteen have been reported missing from the villages near the border. A team was sent out two weeks ago to investigate but no leads were found.

The only witness is a man living in the northern-most town, Hanabira.

Your team has two weeks to find the missing children and return them safely.

Sandaime Hokage.

"It's not much to go on," Hoshiko mused. "And two weeks? What does he mean by that?" She asked, glancing over at the stoic Uchiha as he made his way to the door at the back of the large office. Hoshiko scurried over to him, folding the scroll back up and tucking it into her pocket.

"He probably means that after this time, any hope of finding the children will be gone."

Hoshiko's jesting and irritated mood disappeared when the words left the Uchiha's mouth; her eyes were drawn to the extra photo's that had been with the scroll. There were fifteen pictures, all of the children who were missing. They were all old family portraits that they must've taken and given to the Konoha Shinobi who had tried to find them and failed.

Hoshiko sifted through them all, putting each child's face to memory as she came to the last picture in the pile. Her heart lurched as she gazed into a young boys face; he looked strikingly similar to Sasuke with his dark eyes and hair. Hoshiko wondered if Itachi had seen this picture and that's why he was so guarded and tense right now. It dawned on her that as of right now, all the children who were missing were counting on Itachi and Hoshiko to find them and bring them home.

Itachi could sense the change in her attitude as he looked over his shoulder at her, she was staring down at a picture of a young boy, he could see the emotions of sorrow, guilt and determination run over her face as she met his intense stare.

"We'll find them," she said as the two left the office.

Once outside Hoshiko noticed that Itachi wasn't heading in the direction of the Uchiha compound.

"Where are you going?" She asked him, catching up with his long strides as Itachi looked down at her.

"I promised Sasuke that I would pick him up from the Academy and train with him before our mission tomorrow."

"Can I come?" Hoshiko asked bluntly. Itachi sighed.

"It's not like I could stop you," he muttered as Hoshiko beamed.

"Does that mean you're admitting that I'm stronger than you?" She asked gleefully. Itachi gave her a blank look.

"I mean even if I said no, you would still come anyway," he explained as Hoshiko rolled her eyes at him.

"You like having me around, I can tell," she poked his shoulder as Itachi quirked an eyebrow at her.

"What makes you think that?" He asked her as Hoshiko chuckled, she folded her arms across her chest as she tilted her head back to look up at the clear, blue sky.

"Because I make you remember that you're still just a kid, like me."

Itachi didn't want to admit it out loud, but sometimes, just for a second; Hoshiko made him forget about the clan, about his responsibilities, about the village, about everything that made him who he is today. It was at times like this, through all of her senseless babble, her childish ways and jesting laughter that he realized that he was in fact a kid still, that he was human.

And then the moment was gone, and reality kicked him square in the face.

"You should be more focused, Hoshiko," he said to her. Her smile had disappeared and Itachi felt horrible at the fact that he had made that happen. "We are no longer children in the eyes of the village."

Hoshiko looked away from him, her silvery eyes downcast at her sandaled feet. Itachi had a point; she was going on her first ANBU mission tomorrow, something she had wanted ever since she was little. It was time for her to grow up and face the fact that she wasn't a child anymore.

"You're right," she said quietly. Hoshiko plastered on a smile as she laughed, "I just remembered I have to go home. Ja ne, Itachi-baka," she said, turning on her heel and sprinting away; leaving before Itachi could ask her what was wrong.

"Tadaima," Hoshiko called out dully as she removed her sandals with the balls of her feet. She kicked them to the side where she spotted her mothers neatly tucked away. There was the patter of bare feet as Hiroka poked her head around the corner, a white plate gripped in her hand with a towel as she dried it over.

"Okaeri," Hiroka said with a smile as Hoshiko took a seat at the knee high table. Hoshiko stared at her mothers back, her long brown hair tied up in a low ponytail that reminded her of Itachi's one, she huffed and looked away.

Hiroka, sensing her daughter's distress, glanced over her shoulder as she finished preparing the dinner for them both.

"What's the matter?" She asked with a kind tone as Hoshiko met her kind, brown gaze.

"It's nothing," Hoshiko muttered, looking away sheepishly as she suddenly stood and collected the cutlery for them to use. Hiroka didn't pry so instead she chose to change the subject.

"How did your meeting go?" She asked as Hoshiko set out the chopsticks.

"I have a mission tomorrow with Itachi," she stated, causing Hiroka to gasp in excitement.

"That's wonderful! Your first ANBU mission, we'll have to celebrate!" Hiroka said gleefully as she set out the plates.

Hoshiko shook her head, "Okaa-san, it's fine, don't make a big deal out of it," she asked her.

"I can't help it darling! You've wanted this for so long, ever since you were a small child all you ever talked about was becoming an ANBU." Hiroka gushed as Hoshiko knitted her brows together; she hated it when her mother did this. Hiroka started talking at the speed of light. "Your Otou-san would be so proud of you-our little baby is growing up-you're going to need to watch out for each other when you go-you are both still children and anything could happen to you. I'll have to pack a lunch for you, and make sure that all your clothes are ready…" Hoshiko's frown deepened, Itachi's words were coming back to her.

You should be more focused…

We are no longer children in the eyes of the village…

"—You'll have to be extra careful, I know that ANBU missions are very dangerous and I'll be worrying an awful lot about you—"

"Okaa-san, stop it! I'm not a child!" Hoshiko yelled, slamming her hands down on the table. The plates jumped an inch in the air as Hoshiko's narrowed silver gaze stared at Hiroka's. Hiroka's words died in her throat as hurt flashed across her gentle face.

As soon as the words left Hoshiko's mouth she regretted them, her anger instantly died away as she stared at her mother's hurt expression. She growled in her throat, annoyed that she had snapped like that, it was all Itachi's fault for telling her that earlier in the day. Hoshiko spun on her heel and marched to her room, wrenching open the door and slamming it shut behind her.

"I managed to delay for another two weeks at most, but after then, it'll be hard to stall even further," Itachi told Shisui as the two Uchiha stood on the cliff of the Naka waterfall. Shisui was silent beside him, lost in his own thoughts.

"It's something, at least," Shisui mused as Itachi turned his dark gaze to his best friend.

"I'll be gone for at least a week, you don't think they'll try anything…?" He asked him. Shisui shook his head slowly.

"No, they wouldn't with you gone, they need you, Itachi."

There was another silence between them; the only sound came from the waterfall as it roared before them.

"Itachi…" Shisui began slowly, "The elders have asked me to tail you from now on."

Itachi nodded, "We suspected that this might happen—"

"That's not all," Shisui interrupted him, the two teens locked gazes as Shisui looked grief stricken at what he was about to say. "Fugaku-san asked me about Hoshiko…and you."

"What?" Itachi gaped at him. Itachi's mind flashbacked to earlier in the day, when he and Hoshiko had been walking and talking together after leaving the headquarters. She had been babbling on like she normally did, her smile lighting up the area around herself.

"He asked if Hoshiko knew anything about the Coup."

"She doesn't!" Itachi exclaimed, his heart rate had increased as he steeled himself back into his normal composure.

"I know," Shisui calmed him, placing a comforting hand on his shoulder. "I told him as much. We have to be careful around her now, with everything going on…Hoshiko can't get involved."

There was another silence between them, this time it was filled with tension. Itachi was brooding, he knew that if Hoshiko ever got wind of what was going on behind the Uchiha's compound walls, she would try to stop it…and she would most likely be killed. She would try and stop it for him, and for Shisui and to some extent, Sasuke; she was that kind of person deep down. And now that Hoshiko was in ANBU, there was an even greater chance that the Hokage would assign her to spy on the Uchiha's, like he was currently doing so and a few other ANBU members.

Itachi thought back to the day when he had stopped his father from revealing information about the Coup when she had been perched outside of his window, she had been so close to finding out about him, he had forced her away from the compound, lying to her about his father's intentions for her own protection. But Hoshiko was not stupid, she knew that there was something wrong with the clan, she hadn't heard the important parts but she had heard some of what his father had said, she had yet to confront him about it which just made him believe that she didn't know what to make of it, yet.

And now his father was prying about her, it was no secret that he spent most of his time with her, it would only be natural for his father to be concerned, but if Fugaku suspected even the tiniest amount that Hoshiko knew something, she'd be killed, and he wouldn't let anyone die because of his ignorance.

"Shisui," Itachi said his friends name with hesitation. The older Uchiha steeled his gaze over to him. "When I return, there is something we must do."

Shisui could see the deep meaning behind his gaze as he nodded slowly, completely understanding.

"Hai."

Hoshiko sat on the roof of her home in the dewy pre-dawn light; mist covered the ground as the early morning sun shone through the overcast clouds. A chilly breeze caressed her exposed skin on her arms and face as she traced her fingers over the markings of her ANBU mask. She traced the four whiskers on the cheeks of the porcelain mask and ran her fingers over the defined nose and mouth. A heavy sigh passed her lips as she thought about last night.

She had apologized to her mother later in the night, blaming her nerves about her first mission on her outburst, her mother, ever understanding completely understood and had hugged her and wished her farewell.

She had barely slept that night, she had tossed and turned all night, thinking about her mission, the children that Itachi and herself had been tasked with finding. She hadn't even started her mission and yet something already didn't sit right in her stomach about it; she felt like there was something they were missing, or that they weren't picking up on, but she dismissed it as mission jitters.

Her thoughts dwelled on Danzo and what he had said to her a few days ago in the cemetery. The last time she had been on a mission she had unlocked her Kekkei Genkai and almost killed Kakashi. She wondered if it wouldn't be such a bad idea to go to Danzo, he obviously knew about her abilities, he had said as much, what harm could he do to her?

A large crow flying over her head interrupted her thoughts; she gazed up, her silver eyes reflecting the early morning sun, as they seemed to let off an ethereal glow as she followed it flying off over the village. It soared over the homes, flying up the great stone faces and soaring away. A kind smile decorated her face as she thought about what it would be like to be a bird, to fly high in the sky, to touch the clouds everyday and never return to the ground. When she died, she wanted to come back as a bird.

She felt his presence before he spoke, he was standing behind her, his chakra flow was calm and cool, like always.

"You're up early," he commented as Hoshiko smirked to herself and pushed on her knees so that she could stand up. As she stared over the village, the sun had finally peeked over the horizon.

"I couldn't sleep," she said, still not facing him. She was surprised at herself, normally when Itachi managed to piss her off with his overly-mature mannerisms she would hold a grudge for a couple days at least, but she felt no animosity towards him. Maybe it was because of the truth of his words this time. Hoshiko finally turned around to face her eternal rival. She studied his face, seeing the dark bruises under his eyes and the rumpled clothes on his back. Itachi never looked like that, he was always well rested and his clothes were always smart and neat, it was a shock for her to see him like this.

"Are you ok?" She asked him, concern lacing her voice as she shuffled closer to him.

"I'm fine," he replied firmly.

Hoshiko didn't believe him, and she wasn't really one to force someone to explain their woe's to her, even if she could tell there was something really wrong with Itachi, if he wanted to tell her, he would.

Her gaze travelled down his arm, resting on his porcelain mask that he held in his hand. The mask made her remember their mission as she felt her own mask in her hand. Raising it tentatively to her face she secured it to her forehead protector as she peered through the eyeholes, watching Itachi do the same to his weasel mask.

"Let's go," Itachi said to her as she nodded and the two of them dashed away.

They leapt swiftly through the trees, if one was standing below, they would've only heard the faintest of noises, a brief rustle of leaves and the quiet thud of their shoes hitting the thick bark. You wouldn't be able to pinpoint where they had come from or where they had disappeared to they were that fast.

Itachi was a meter behind Hoshiko; the young teen was leading their duo, her chakra senses extended around them, making sure that they had no pursuers or ambushers. Itachi was glad, as it gave him time to study her body language, she was tense, he could tell from the way her shoulders were drawn in together. Her fists were balled up at her sides as she landed on a branch and then pushed off, the power in her legs created an indent in the bark.

He couldn't tell what she was tense about, it may have been the mission, or what had happened the previous day between them, or the way he had brushed off her inquiring question a few hours before. She hadn't spoken a word to him since they left Konoha, it was strange for her not to prattle on to him like she did back home; Itachi realized that this was the first mission that they had ever partaken together and perhaps he had misjudged her.

"It must be an urgent matter, for you to have asked for me at this time of night," The Sandaime mused as he puffed his wooden pipe. The old man turned slowly, seeing Itachi knelt on the wooden floor before him. The young teen looked exhausted and troubled, something that was becoming ever familiar to him from the weight of spying on his family clan.

"Forgive me," Itachi said with a bowed head. "I felt the need to talk with you immediately."

"Is it about the Coup?" Hiruzen asked with concern. Itachi shook his head.

"Not directly," he explained, causing the Sandaime to frown. The old man took a long draw from his pipe and exhaled, the smoke spiraling high into the air.

"Go on."

"Uchiha Shisui has been ordered by the clan elders to tail me from now on. He will be feeding them false information," Itachi explained as the Sandaime nodded slowly.

"There is more?" He guessed.

"Hai. I have a request…" Itachi said hesitantly. At this the Sandaime inclined his head to the side; his interest peaked. "If possible, I would like Ginyoru Hoshiko to be left out of the Uchiha affairs."

The Sandaime stared at the young boy; he could tell that something had happened. Itachi rarely made any requests, he had always been very complacent, for him to request something as dire as this, it was important.

Itachi could see that the Sandaime was confused at his plea; he cleared his throat, gaining his attention once again. "The clan suspects that she knows the truth. She doesn't, but to illuminate the prospect of innocent bloodshed she should be kept far away from them. I don't doubt that they would silence her if she did discover the truth."

"Hoshiko is an ANBU, and a skilled one at that, she is valuable for infiltration and spy work," the Sandaime argued. He could see where Itachi was coming from, but as he said, Hoshiko was a Shinobi of Konoha first and foremost. "It would be in our best interest to have her working with you to stop the Coup."

"Then an ultimatum," Itachi said firmly, his onyx eyes meeting the Sandaime's murky brown. "I will ensure that she never harms another person with her Kekkei Genkai again. I know it had been brought to the advisors attention that she is dangerous, if she found out about the Coup, I wouldn't doubt she would try everything to stop it."

There was a tense silence between them both, the two Konoha Shinobi stared the other down, waiting for the other to back down. Itachi hadn't wanted to resort to this, but he saw it as the only way to make sure that Hoshiko wouldn't wind up dead. She would probably hate him if she ever found out, but Itachi was prepared to take that burden on his shoulders, he wouldn't let innocent blood be spilt.

"Is that all?" The Sandaime asked him with his piercing gaze. Itachi nodded once. "Then I agree to your terms." There was a pause. "But if she should hurt another person, then she will be placed on the surveillance team stationed on the Uchiha watch. Good luck on your mission tomorrow."

"Thank you, Hokage-sama."

"What do you know about Danzo?"

Itachi glanced up from sharpening his kunai, his onyx eyes cut to Hoshiko who was lying on her back on the grass; her arms folded behind her head. They still wore their ANBU masks so he couldn't see her expression but he could tell she probably had a furrowed brow.

They had made camp for the night a few hours ago, Itachi fetching dinner in the form of fish he caught from the nearby stream. Hoshiko had been impressed by his cooking ability, "Didn't know you were a cooking genius, it's to be expected I guess," she had said to him with a smirk as Itachi 'tsk'd' and rolled his eyes at her.

"You should be sleeping," Itachi, told her, avoiding the question.

He could hear her eyes rolling.

"I can't sleep if you don't answer the question," she retorted.

"Then you'll be tired when I wake you up for your guard shift," he replied coolly. He heard her sigh in annoyance as she fell silent once more.

It had been a minute since she had spoken, and Itachi thought that maybe she had taken his advice and had actually gone to sleep. He realized that she had actually been planning her prodding once again when a small stone hit his mask.

Dink.

The stone plopped into the grass as Itachi glared at her through his small eyeholes. He heard her snort as she sat up.

"You're so grumpy with me lately," she remarked to him.

"I'm not grumpy," he snapped back, fueling her laughter even more, Hoshiko chuckled at him.

"Could've fooled me."

"Sleep, Hoshiko." He ordered to her. The girl sighed and lay back down on the grass.

"What did I do? Did I say something wrong? You've never been like this with me before," she muttered.

"Because I don't want you—"

Itachi paused, the words dying on his tongue as he stalled himself from what he was about to say. He had been about to say, because I don't want you to get hurt. He couldn't say that to her, he had almost though, he hadn't thought about what to say, it had just come naturally to him, and that's what made him all the more anxious.

She had asked him about Danzo, a man he knew as manipulative and cunning and always three steps ahead of the Hokage. Itachi wondered why she had asked about Danzo so suddenly, it had reached his ears that Danzo had asked for Hoshiko to be placed in The Foundation, maybe he had offered her a place again, Hoshiko couldn't be that stupid to accept though, could she?

And on the other hand, she wasn't sleeping, which would make her tired for their mission, and put them both at risk. It was true that he didn't want to see her get hurt because of this but he had to put his mission first and his friendship with Hoshiko second.

"Because what?" Hoshiko asked him, he could hear the inquiring tone behind her mask as her face angled to his. He studied her cat mask for a second before picking up his kunai and stone before starting to sharpen it again.

"Because I don't want you jeopardizing the mission with your irrelevant and nonsensical questions when you could be taking this mission seriously," his tone was like ice and if possible he felt the air around Hoshiko and him drop a few degrees.

Hoshiko's mouth parted in surprise at his words, she had never been spoken to like that from Itachi before. Even yesterday, when he had told her to stop acting like a child after their mission brief he had spoken with a kind tone, this one was harsh and uncaring. She felt an uncomfortable stab in her gut as tears pricked at the corner of her eyes, she couldn't wipe them away because of her mask and she wouldn't have anyway as Itachi would've realized that he made her cry. Instead she steeled her composure and brushed it off.

"Just because I asked a question doesn't mean that I don't take this mission seriously," she said with a snarl. She shook her head at him, the anger coursing through her veins at his words as Hoshiko rolled over so that her back was facing away from him. "You're such an asshole sometimes," she muttered quietly, but loud enough for the stoic Uchiha to hear her words.

The next few days passed in complete silence for the two teens, neither spoke to the other unless it was about the mission. Itachi took the lead for them both and was always a meter ahead of Hoshiko as she kept behind, her face was set in an almost permanent frown because of what transpired between them. She was mad at him for being so rude to her about a simple question, he had over reacted.

It was only on the third night, the day before they were to arrive in the village that Itachi broke the uncomfortable silence between them.

"Why did you want to know about Danzo?" He asked suddenly to Hoshiko.

Said girl had been eating the meager dinner that Itachi had brought along for their final night of camping. Her mask was removed for her to eat and rice stuck to the corner of her mouth as her silver eyes cut to his as he sat across from her. His own mask had been pulled to the side so that he could indulge in the bland food. Itachi looked away from her piercing gaze as he stared at the bush behind her head.

Hoshiko finished eating as she wiped her hands on her trousers and didn't bother lowering her mask back down, she was glad to finally have it off her face after the long day of traveling.

"Are you sure you want to answer that? I mean, it's an irrelevant and nonsensical question," she repeated his words from two days ago to him as Itachi inwardly flinched. After the words had left his mouth that night he regretted them, he had indeed been too harsh on her.

"Forgive me," he muttered quietly, barely above a whisper. Their eyes met once more as Itachi bowed his head slightly to her, "I shouldn't have said that."

Hoshiko sighed, a gentle smirk on her face, "Usuratonkachi."

Itachi's eye twitched in annoyance as he narrowed his gaze at her. He let her insult slide as he spoke, "Are you going to answer my question?"

Hoshiko's eyebrow's rose as a sly look came over her face as she smacked her hands down on her knees as she leaned closer to him, "Oh ho! Look who's talking? If I remember correctly, you were the one who wouldn't answer mine! I'm not saying a damn thing until you answer mine first, usuratonkachi."

"Stop calling me that," Itachi quipped.

"Call you what, usuratonkachi?" Hoshiko asked, her voice laced with sarcasm as Itachi rolled his eyes at her and 'tsk'd'.

"Fine," Itachi said in exasperation. "Danzo is a village elder—"

"Everyone knows that, usuratonkachi," Hoshiko interrupted in a bored voice. Itachi silence her with his onyx eyes bleeding crimson with the Sharingan as she giggled, reveling in the fact that she had annoyed him to the point of his Kekkei Genkai activating.

"He is a village elder who runs the division called The Foundation. A group of Shinobi that work underground protecting Konoha from the shadows."

"I know all of that already, I was told before my exam about them. I want to know what his deal is! Why did he create them? What's so special about his Shinobi?"

Itachi furrowed his brows at her, she was pressing this subject an awful lot, it made him think that something had happened between them, or the worst possibility, Hoshiko wanted to join them.

"I don't know why he created The Foundation, not many people do. I suspect only Danzo and the Hokage would know why. But the reason why his subordinates are so feared is because he trains them to become mindless and emotionless killers."

"What do you mean?" Hoshiko asked. She was completely transfixed on Itachi now.

"He raises them from children, forcing them to fight to the death when they come of age. He makes them kill off their emotions so they feel nothing and only do his will…"

Itachi could see the disgusted look in her silver eyes, this was news to her. Hoshiko was disgusted at the fact that Danzo would make children fight their friends, the people they had grown up with; and kill them with the sole intent of turning them into assassins. Hoshiko was all for protecting her village, but that seemed barbaric. It was like the Blood Mist Village.

"Hoshiko…" Itachi said her name slowly; his dark eyes met hers. "Has Danzo approached you?" He asked her. He saw the slight widening of her eyes, the nervousness behind them as she shook her head and stretched her arms up high.

"Of course not, I just wanted to know," she said with a fake smile that Itachi immediately saw through.

Why are you lying? What are you hiding from me? Itachi thought as Hoshiko wished him goodnight and made herself comfortable on the ground.

With her back to Itachi, he missed the worried look on her face.

In case you didn't know, Usuratonkachi basically means 'useless' in Japanese and is what Sasuke frequently calls Naruto. I just find it a funny insult and I guess we'll find out where Sasuke gets his bad potty mouth from, ne? ;)
