It was another beautiful day in the Leaf village. Asuka Nakamura laid on the grass in the park staring up at the clouds. It was hard to believe it had been three years since she had become a Chunin. Despite living in the Leaf Village since she was 11 years old she hadn't really made friends with anyone. She knew the names of a few of her class mates either because Sensei either scolded them or praised them. Asuka sat up and ran her fingers through her long blue hair. She then pulled out one of her kunai knives and inspected it closely. She didn't specialize in weapons or anything but she often found herself being picky about them and almost obsessionally inspected them. This one still looks good but may need some sharpening soon. She thought. She put the knife back and flopped back on the grass and gazed up at the clouds.
"Something bothering you?"
Asuka was so startled that she leaped to her feet and drew her kunai in under five seconds. She stopped herself once she saw it was Kakashi. Asuka had heard Kakashi's name and had seen him around but she never actually had a conversation with him and knew little about him.
"With all due respect sir don't you know its not nice to sneak up on people?!" Asuka said panting and heart still racing from the adrenaline.
"Sorry scaring you was not my intention." he responded coolly, then pausing allowing Asuka to catch her breath, "So back to my question, is there something bothering you?"
"No sir, I was just thinking. Was there something you needed?"
"Lady Tsunade asked me to check up on you."
"I didn't realize the Hokage noticed me."
"She mentioned that you work well in a team but since becoming a Chunin you haven't asked anyone to mentor you."
"I haven't met anyone who really knows a whole lot about my jutsu, sir."
"Well what would you say to becoming my student?"
Asuka thought for a moment.
"I think that if you are up for it then I would gladly accept any training you could give me Kakashi Sensei."
"Alright then, we will start tomorrow morning."
After Kakashi left and Asuka laid back down on the grass staring at the clouds she suddenly got a wave of panic as she remembered another reason she never put a lot of effort into finding a Sensei.
The next morning Asuka met up with Kakashi at one of the training grounds just outside the village.
"Ok first I would like to see what you can do so that I can assess your skills and see what needs work."
"Forgive me Sensei but how will you be able to help me without possessing the same jutsu?"
"I will watch you with this." Kakashi said as he straightened his headband and revealed his sharingan eye. Asuka had read up on the sharingan so she knew about its abilities.
"Alright good enough for me." Asuka then turned so she was perpendicular to Kakashi.
"Ice jutsu: Hailing Kunai." Asuka said making the correct hand signs. Several ice kunai appeared above her head and completely shredded a tree that was about 25 meters away. Kakashi went over to inspect the tree and noticed that the cuts in the were not rough. Kakashi was impressed. He turned around to give feedback to find Asuka had striped down to her sky blue and snowflake pattern bra perfectly holding her size D breasts and panties.
"Asuka! What are you doing!?" Kakashi shouted as he covered his eyes.
Asuka looked down at herself realizing she had done what she had feared of doing.
"I'm sorry Kakashi Sensei, I meant to warn you about this, I didn't think I would do it this soon in training." Asuka responded in rushed tones.
"Don't apologize for showing off that beautiful bod of yours." came a pervy type voice from the bushes.
"I know that voice," Kakashi said daring to look again but trying to look past Asuka, "is that you Master Jiraiya?"
"It sure is." came the response as a bulky man with long white spiky hair emerged.
Kakashi stepped in front of Asuka to shield her from Jiraiya's eyes... as well as his own.
"Pervy Sage! Where are you?" came another voice.
"Over here Naruto!" Jiraiya responded.
A boy around Asuka's age came out of the bushes with blonde spiky hair.
Naruto looked at the situation.
"Pervy Sage! What's with you spying on girls all the time! I oughta tell Grandma Tsunade on you!"
"Aw come on Naruto you can't even deny the beauty of this ice queen."
"I can't see her cuz Kakashi Sensei is standing in the way." Then it hit Naruto that Kakashi was there too. "Hey just what are you doing here Kakashi Sensei? Don't tell me Pervy Sage here got ya into some bad habits."
Asuka stepped out from behind Kakashi.
"Actually Naruto, Kakashi Sensei was training me. This is just a bad habit I picked up from the training I had with my mother."
"I wouldn't call it a bad habit." Master Jiraiya piped up.
"How is stripping part of your training?" they all asked together.
A smile crossed Asuka's face. She never dreamed that this habit of hers would create such a humorous response and after the initial shock of Kakashi Sensei's reaction she felt comfortable in her own skin. Even though Master Jiraiya was pervy Asuka found it nice to be complimented on her body. She then remembered that they had all asked a question and they looked at her expectantly.
"Before moving to the Leaf Village my mother and I traveled all over. When I told my mother I wanted to become a shinobi she took me to the Land of Iron to train. My mother said that our clan's specialize in ice so she said that in order to wield ice we need to become one with the ice. We did this by going out into the snow and striping down." Asuka explained gesturing to herself. "Eventually, I started doing it without realizing it, thus the awkward moments."
Asuka put her clothes back on.
"Even though those of us present will get used to this little quirk of yours it would probably be best if you find a way to stop doing it. At least when your on assignment. We don't want it hindering you in the middle of a mission. Consider it as part of your training." Kakashi concluded.
"Alright I will do what I can, Sensei," Asuka replied.
"Well it was nice to meet you Asuka but I want to get back to the village." Naruto said.
And with that Naruto and Master Jiraiya left Asuka and Kakashi to their training. They trained for the rest of the day then parted ways.
Asuka walked home pondering about what Kakashi had said. I wonder if there is a way to break myself of this habit. I tried breaking it before but it ended in vain. She sighed and continued thinking as she walked. Once she got home she made herself some ramen for dinner and slowly savored it as she did some more thinking. While in the middle of eating there was a knock at her door. When she answered the door she was surprised to see Naruto.
"Hi Asuka, Kakashi Sensei told me where I could find your place."
"Oh, okay," Asuka responded still wondering why Naruto would come visit her.
"Hmm? Something wrong?" Naruto inquired.
"No, I'm just not used to people coming by. I don't really know anyone very well."
"Okay. Anyway can I come in I want to run some stuff by you."
"Sure c'mon in." Asuka invited. There was something about Naruto that just put her at ease. It was like she had known him her entire life. "Sorry about the mess, as I said I'm not used to people coming over."
"Don't worry about it, my place is usually way worse."
"I was just in the middle..."
"I smell ramen!" Naruto interrupted excitedly.
"Yeah its one of my favorite foods so I always make sure I have it in the house."
"Mine too!"
"Would you like me to make you some?" Asuka offered seeing how excited Naruto was getting.
"You would share your ramen with me!?"
"Of coarse, for someone who likes ramen as much as you seem to it would be torture for me to finish eating mine in front of you without offering you some."
"Asuka, I have the feeling that this is the start of a beautiful friendship!"
Asuka then continued to prepare Naruto a bowl of ramen. After she handed it to him she remembered that he had come to run some ideas by her.
"So Naruto, what was it you wanted to run by me?"
"Oh right, I was thinking about what Kakashi Sensei said about you breaking your habit, and I thought that if you dressed in such a way that you felt like you already had removed your clothes then you wouldn't feel the need to take them off."
Asuka was surprised. She had never thought of something like that, yet it was so simple.
"Naruto that is a fabulous idea but there is only one problem I see with it. How do I do that without showing too much?"
"I don't know but I figured you could just try stuff till you find what works."
"Why do you care about this anyway?" Asuka asked.
"When I reported to Grandma Tsunade I asked her about you and she told me you didn't have any friends and after our first encounter I figured that was why."
Asuka smiled. This was the first time anyone went out of their way to make friends with her, and this was after finding out about her "quirk". Naruto was really something special and a friend she knew she would want to keep around.
"Thanks Naruto, its been nice hanging out with you."
"Hey I have an idea! Why don't you meet me at Ichiraku's tomorrow at lunch for ramen and I'll introduce you to my friends."
"I would love that." Asuka replied gratefully. She figured that since Naruto was making an effort for her to make friends then so would she. She was always shy in groups but she hoped that once she got to know everyone she would be able to loosen up. Just then Naruto let out a big yawn and a stretch.
"I guess it's time for me to head home and wind down." Naruto said.
"Alright I will see you tomorrow."
After Naruto left Asuka flopped on her bed and stared at the ceiling.
"First training with Kakashi Sensei and made friends with Naruto all in one day. I doubt my life will ever be the same." she said aloud. After a while, even though she didn't realize it, she drifted off to sleep.
