Kakashi's face was extremely close to Ryu's. In fact, if she licked her lip she would probably lick his also. A furious blush was on her cheeks and a smile had made its way onto Kakashi's face. "What are you doing, Kakashi?" She asked. He chuckled a bit.

"I don't know." He replied and crashed his lips against hers. It was her first kiss. Honestly, she never imagined it would be with Kakashi. Even as a child, she was more boyish, having to have had toughen up to the villagers' hateful words directed at Naruto and her. She had thrown herself into training to be the strongest kunoichi that she could be.

She could feel his hand move down, to her waist and suddenly pinched her side, making her gasp and slightly flinch closer to him. He took the advantage of her gasp and slipped his tongue in. He gently coaxed her own to join him. Ryu's hands went up and buried themselves into Kakashi's hair.

Kakashi gently pulled away but he lingered and gently kissed her once more. Knocking startled the both of them apart, and Ryu had a bright red face and Kakashi returned to laying down and covering his face with the blanket. Before Kakashi could say "Come in." to the visitor, Ryu disappeared with a yellow flash.

~The Kyuubi Twins~

It was the fourth day Team Kakashi had been gone and Ryu was avoiding Kakashi. Each time she let her mind wander, she would think of the kiss and her face would go as red as Hinata's whenever Naruto was near. Tsunade called Ryu to her office with an ANBU that had a Hawk mask.

She vaguely recognized the voice but couldn't place it. "Ne, Hawk-kun, I recognize your voice from somewhere but I can't place it. Care to tell me?" She said to the ANBU she was following.

"ANBU are not suppose to reveal their identities to others." Hawk replied.

"Oh, calm on. I'm ANBU too! You can tell me." Ryu pouted. Hawk shook his head.

"I know you are, Ryu." Hawk said. Ryu blinked. She frowned and put on a burst of speed, surprising Hawk when she caught him up to him and reached for his mask. Hawk dodged last minute but Ryu settled for pulling the hood off. She recognized the hairstyle instantly.

"Did you think you could hide the fact from me long?! Ne, Sasuke?! Even if I didn't do anything I could have just gone to headquarters and looked!" Ryu said, grinning. Sasuke sighed and shook his head.

"She just had to send me to get you…" He muttered under his breath.

"You'll have to call me senpai! Since I was in ANBU way longer than you." Ryu said, nudging Sasuke. He narrowed his eyes.

"Rejected." He denied.

"Call. Me. Senpai, okay?" She smiled, however the air around her said, 'Or else.' Sasuke gritted his teeth in irritation.

"Fine." He said reluctantly. Ryu's eyes shined with victory. "Anyways, how's Kakashi?" He asked. Ryu's face instantly flushed red.

"H-he's fine! J-just stuck on bed red for a week, dattebane!" She replied hastily, starting towards the Hokage Tower again. Sasuke frowned and followed. When they finally arrived, Tsunade yet again threw another paperweight at Ryu. Ryu caught it easily before it could hit Sasuke since she had dodged instinctively.

"You called?" Ryu asked. Tsunade nodded.

"I need you to deliver something for me to Kakashi." She said.

"W-what! Why not have Sasuke deliver it?!" Ryu protested, she was trying her hardest to not blush but a pink twinge showed. Tsunade blinked and then smirked.

"Oh? Did he finally act upon it?" Tsunade said curiously. Ryu frowned.

"Huh? What do you mean?" Ryu asked.

"Oh, nothing. Sakura has told me that you liked Kakashi. But she didn't know how to help you so I kindly directed her to search up family bloodlines." Tsunade replied.

"What! So that's where she got the information about the Hatake line and their…." Ryu trailed off. Tsunade nodded.

"So, it's an uttermost importance that you deliver this." Tsunade said, handing Ryu an envelope. Ryu sighed, defeated.

"Is there anything else?" Ryu asked. Tsunade shook her head and dismissed her.

As Ryu arrived at Kakashi's room, she heard voices and frowned. She knocked and opened the door. She saw that it was Naruto, Sakura and someone else she didn't recognize.

"Ah! Ryu!" Sakura said, waving. Ryu smiled.

"When did you guys get back?" Ryu asked.

"Not too long ago." Sakura replied. Ryu walked over and met Kakashi's gaze and blushed. Sakura caught the blush and looked between the two then grinned.

"Anyways, who is this?" Ryu asked, her gaze at the black haired male.

"Oh, this is Sai. He replaced Sasuke on Team Kakashi because Sasuke is too busy with ANBU missions." Sakura answered. Ryu nodded and stuck out her hand.

"Nice to meet you, I'm Uzumaki Ryu, Naruto's twin sister." She greeted. Sai took her hand and smiled back.

"Can I call you…-" Sai said, about to give Ryu a nickname but Ryu cut him off.

"Ryu. Just Ryu and nothing else." Ryu said with a smile that promised pain if he didn't do so.

"Alright…" Sai said hesitantly.

"Anyways, was I interrupting anything?" Ryu asked. Kakashi shook his head.

"No, I was about done explaining." He replied. Ryu noticed the Icha Icha book in his hand. She narrowed her eyes at Kakashi and he sighed, closing the book. Naruto blinked at the exchange and leaned over to Sakura, whispering,

"Do you think there is something going on between those two?" He asked. Sakura grinned.

"Hopefully!" She replied excitedly. The door banged open.

"How are you doing, Kakashi?" Asuma said.

"Asuma-sensei, at least knock!" Ino scolded.

"Hi!" Choji said through his munching. Shikamaru greeted Naruto and Sakura. Ryu however was having a glare fight with Kakashi. He refused to back down and so did Ryu. The tension rose and everyone felt a sudden chill.

Everyone turned and they blinked twice to make sure their eyes weren't playing tricks on them. What they saw were sparks flying between Kakashi and Ryu in their intense glare fight. But they got the feeling it was like a fight between a wolf and fox and neither would back down.

Asuma suggested that his team and Team Kakashi go to BBQ and that it was on him, since he needed to talk to Kakashi about something. With one last glare, Ryu turned and went with them.

~The Kyuubi Twins~

They were all talking and eating cheerfully with each other, but Ryu wasn't paying much attention. She was doing the motions of eating but not really processing them. Sakura kept on giving Ryu some looks that said she really wanted to know what's going on between Kakashi and her.

Sakura was just about to ask Ryu when after Ino introduced herself to Sai, he gave her the nickname, 'Pretty Lady', which made Sakura mad because he had given her the nickname, 'Ugly Dog.'

"SHANNAARRROOOO!" Sakura yelled, raising fist to punch Sai as hard as she could. Naruto grabbed Sakura and was trying his hardest to stop her. Naruto called out desperately to Ryu.

"Help me, Ryu! I think you're the only one with the strength to stop Sakura completely because you were also trained by Tsunade-baachan, dattebayo!" Ryu sighed and leaned over to whisper in Sakura's ear.

"Kakashi kissed me." She said simply. Sakura instantly stopped trying to punch Sai and turned to Ryu.

"REALLY?!" Sakura said excitedly. Ryu nodded. Sakura pumped a fist in the air.

"Yes! Now time to get you two together! I have to get shishou in on this…" Sakura said murmuring to herself. Ryu shook her head and sighed, her cheeks pink.

~The Kyuubi Twins~

The next day was one that Ryu had to herself. She was cleaning up the apartment she shared with Naruto. Since he was out training with Kakashi, she would have no one bothering her, or so she thought. When she finished cleaning Naruto's room, which was beyond messy, Ryu heard the knocking on the door.

When she opened the door, she really wished she didn't. Standing there was Sakura, Ino and Hinata. "What are you guys doing here?" She asked.

"Operation Get Kakashi to ask you out on a date, of course!" Sakura replied. Ryu shook her head.

"Oh, no way! Do you remember the last time I tried? I got scolded!" Ryu said, protesting. Sakura grinned.

"This time, it will work." She reassured. Ino and Sakura grabbed Ryu's arms and dragged her to Sakura's house with Hinata following.

It was hours later when the three of them relented on giving Ryu a make-over. They had curled her hair in gentle waves and gave her some color on her lips, making it soft 'kissable' pink as they stated it.

They gave her a whole new outfit, telling her that the ANBU outfit she always wore was not pretty at all. The outfit was a light blue with one side being sleeveless and the other being a long sleeve that flowed down, which was also good for hiding kunai. They gave her thigh-high boots which with the outfit covered the right side, going down to her knee and leaving the left side showing, which was fine because she was wearing shorts that went with the outfit. The outfit showed off her breasts, because there was a corset-like cloth that went across her midriff. Lasting there was an arm-bind that went from the middle of her bicep to her elbow.

"There, you're done!" Sakura announced. Ino nodded, agreeing. Ryu smiled and bent down to grab her weapon bags and was skillfully able to hide them in the outfit but still allow her to easily access them. "Now go to Kakashi! He's training Naruto so I think you know where he is." Sakura said, pushing Ryu out the door.

~The Kyuubi Twins~

Ryu arrived at the training area as Kakashi was explaining chakra types to Naruto. Kakashi gave Naruto the paper used to tell one's type and after a second or so of concentration, the paper in Naruto's hand split into two. Ryu walked up and Kakashi turned to her, his eye widening in response.

"Ohh! Ryu, you changed your outfit!" Naruto said, surprised. "Are you still in ANBU then?" He asked. Ryu nodded.

"Yea, but I thought of changing what I wore for a bit. I wanted a change." She replied. "Does it look nice?" She asked, twisting her body right and left. Naruto nodded and gave a thumbs up. Kakashi blinked and turned his face away.

"Honestly, Sakura, Ino and Hinata chose this for me. It's easy to move in yet also pretty at the same time. And it covers my ANBU tattoo so that's a plus." She said, moving her right shoulder, which was where it was. She was looking at Kakashi pointedly and he refused to meet her eyes.

"It's nice on you." He said, nodding in her direction but still not meeting her eyes.

"Oh! Sis, what's your chakra type?" Naruto asked suddenly.

"Lightning and Wind. Though I have more control over lightning than wind…" Ryu replied, shrugging. "Are you going to use Kage Bunshin to train?" Naruto nodded.

"How many do I make, Kakashi-sensei?" Naruto asked. Kakashi pointed to the tree he was standing in front of.

"That many." He said, talking about the leaves. Naruto nodded and went to his training. Ryu pouted at Kakashi which he noticed and blinked, startled.

"What?" He asked.

"Just it's nice? Nothing more?" Ryu replied. Kakashi sighed and reached over to ruffle her hair but she ducked under his hand. "I'm not a kid, anymore!" Ryu protested. His eye softened and he pulled her into a hug.

"I know you aren't." He said softly. Ryu relished the warmth that radiated from Kakashi. She wrapped her arms around him and hugged him tighter.

"We haven't gone on a mission together in a while." Ryu said into his chest.

"I agree." He replied. "But our missions are rather dangerous." Ryu sighed.

"I think Tsunade is trying to keep me from going on any missions alone. Now that Akatsuki is actively going around and going after jinchuriki." Kakashi froze up and hugged Ryu closer to him. Ryu wiggled a bit from the discomfort.

"I think Tsunade should. Don't go on a mission without telling me first, alright? And never alone." He said seriously, holding Ryu out in front of him and into her eyes. She frowned.

"What about Naruto, huh?" She asked. Kakashi shook his head.

"He's still ranked as a genin, he'll always at least be in a four-man squad. It's you I'm worried about. You're a jounin and ANBU. You can be sent out on S-rank missions." He reached up and gently caressed her cheek. He leaned down and gently placed his forehead against hers. He closed his eyes and softly whispered, "I don't think I will be able to handle it if I lost you too."

Ryu closed her eyes and listened to his breathing. A soft pressure on her lips made her open her eyes. Kakashi had gently brushed his clothed lips against hers. A cough made Kakashi stand up straight and Ryu turn her head with her cheeks tinted pink. "Kakashi-sensei, Isn't there anybody else in Konoha with the 'Wind' element?" Naruto asked.

"...You want to get some tips?" Kakashi replied. Naruto nodded. "Well, there is somebody but...he should be playing shogi around this time." Naruto frowned a bit confused.

"Asuma, he means." Ryu interrupted. "He often plays shogi with Shikamaru." Naruto hit his fist against his palm in understanding.

"Ok!" He ran off to go find Asuma. Ryu watched as he ran off. She turned to Kakashi and smiled.

"Well, it's time for me to go too. I think Sakura, Ino and Hinata are waiting for me to come back to see if their plan was successful or not." She shrugged. Kakashi blinked and tilted his head to the side in curiousity.

"Was it successful?" He asked. Ryu shrugged one shoulder.

"Don't know. Their plan after all was to get you to take me out on a date. Either way I think it was successful." She replied. Kakashi sweat-dropped. Ryu twisted this way and that, looking at the outfit she was wearing. "I think I'll keep this outfit. It makes me feel like a girl. I'll just wear my black cloak over this if I'm going as ANBU."

"Think that's a good idea?" Kakashi frowned. Ryu nodded.

"I can move quite easily in this and I don't feel that anything is restraining me. With this sleeve, I can hide quite a couple of weapons if needed." She said, pointing it out. "But if it's a strictly ANBU mission, I'll wear the standard." Kakashi nodded in understanding.

"Then, I'll be off then." She waved to Yamato and disappeared in a flash of yellow.

~The Kyuubi Twins~

The next day, Ryu was heading towards the training grounds where Naruto was supposed to be training when she noticed them at Ramen Ichiraku. She walked in and sat beside Kakashi and greeted Teuchi and ordered the same as Naruto.

"How is the training?" Ryu asked.

"He mastered changing his chakra to wind." Kakashi replied. Ryu grinned.

"I wonder how well he's going to master it." She said thoughtfully. Kakashi sweat-dropped.

"I don't think he's going to master it to the point you did." He sighed. "I saw that punch you pulled on Deidara. Not only did you have it infused with chakra, making it already extremely dangerous to even get lightly punched but you even changed your chakra into lightning?! I think a punch from you now is just plain old deadly."

Ryu still had her grin on her face. "I'm called a demon, why not live up to it?" Her order was placed in front of her and she dug in. Though she was eating it rather quickly, it was quiet. Kakashi stared at her for a bit. He had already finished his ramen.

"You've learned how to eat it quickly from me didn't you?" He asked. Ryu nodded, swallowing.

"Don't you remember? Whenever we were on missions, you told me to eat quickly whenever we had a break from heading to our destination because enemy ninja could attack at any moment and you of course had already finished your food." Ryu replied, continuing to eat and swallowing once more. "It took my stomach a while to get used to having food that fast." She frowned, sending a glare at Kakashi.

Naruto placed his bowl down after finishing the soup. Ryu finished about the same time he did. "Alright! I'm re-energized now, let's get back to work!" Naruto said, about to stand up with Kakashi stopped him.

"Easy. I have to explain a few things first." Kakashi said. Naruto reluctantly sat back down. "Naruto..I've got something extremely cool to show you.."

"Cool?" Naruto asked curiously.

"Well, I also have a number of things to explain before we end our lunch break."

"What?! I've had more than enough explanation already!" Naruto said, protesting.

"Don't worry...I have a way with words so I'll get you in the mood, no problem." Kakashi reassured. Ryu sweat-dropped. Kakashi stood up and Naruto and Ryu followed him. "Yamato, here, if you wouldn't mind." Kakashi said, telling Yamato to treat them.

"What!? Isn't it the senpai that's supposed to pay in these situations?" Yamato protested.

"In my eyes, once I respect you, senpai and kouhai mean nothing...granted...you're pretty much the only kouhai I've ever respected…" Kakashi replied, then sighed. "Although, I suppose I should…" He trailed off. Yamato stood up, feeling flattered.

"Oh no! I'll take care of everything!" Yamato insisted. Ryu sweat-dropped and quietly snarled at Kakashi,

"You ever do that to me and I'll make sure you'll regret it."

"I know better than too." He replied. The four of them went to the training grounds that they had been previously using. Kakashi started explaining the difficulty in making a new jutsu and Ryu quickly lost interest.

As Kakashi was explaining, Ryu reached up to Kakashi's left ear which was covered by his hair. She felt along his ear, which he did his best at ignoring her and felt the piercing in his ear which held the chakra receiver that was connected to the earring in her left.

Ryu sent a bit of chakra into the earring in hers and felt the one in his ear warm up a bit. "What are you doing, Ryu?" Kakashi said, jolting Ryu out of her slight daze. He had finished explaining everything to Naruto.

"Did you get this, knowing that you would give me it's partner to me?" She asked, releasing her hold on his ear. He nodded, pulling out his Icha Icha book and opened it to the page where he had left off. She frowned but didn't do anything about it.

A loud clap of thunder startled Ryu and it started pouring heavily. She looked up at the sky with narrowed eyes. "I'm gonna go home in safety from this rain." She said. Kakashi nodded and Ryu disappeared.

It was a couple hours later when she got the news that Asuma had died in battle. Ryu stood by Naruto who was comforting Konohamaru. She silently walked over to Kakashi and without a word, weaved her fingers with his, tightly gripping his hand. He silently understood what she was trying to say and gripped her hand in return.
