Tsunade snickered as Nitsu was now back on her stomach, afraid to move for fear of the guys seeing her exposed. And since she wasn't on the small side, she had to use her arms to cover what could be seen from her sides.

Sakura looked at her back in surprise as Tsunade told the boys to turn back. They blinked several times when they noticed Nitsu's bare back.

Kakashi walked up, "What does it mean?"

"It means Hokage-sama's a hentai," Nitsu mumbled.

Naruto and Sasuke faintly blushed and tried to focus on her back.

In the middle of her back was an intricate marking. It started about three inches from the base of her neck and ended halfway down her back. The width was about seven inches.

"Nitsu, what is this?" Sakura asked as she looked over at her face.

Said girl shrugged, "Dunno, I've had it as long as I can remember."

Tsunade touched her back making Nitsu jump slightly, "Did that hurt?"

Nitsu shook her head, "Cold fingers!"

The blonde woman chuckled, "Has it ever done anything, like hurt or burn?"

"Just a few times. But nothing major. Why?" she asked cautiously as she turned her head to see the woman better.

"I'll need to run a few tests to see what it is," she sighed as she walked out.

Nitsu took a deep breath and was about to move when she stopped and looked to her left where the guys stood, "What?"

Kakashi tugged Naruto with him after Tsunade, trying to figure out something.

Nitsu shrugged and dozed off into a peaceful sleep.

Sakura looked around and sighed, "I'll go see what's going on. Can you wait here until she wakes up?" She left before Sasuke could answer.

The Uchiha looked back at the sleeping girl and sighed as he studied her back. Even though he would never admit it, she was more attractive than the other kunoichi's in their village and the fact that she didn't stalk him was always a plus.

He lightly traced the markings as he thought about what they could mean, when Nitsu twitched slightly. The raven watched as he traced them again, making her move more. As he finished following all the markings, she sighed and peeked an eye open at him.

"What are you doing Uchiha?" she asked him as she carefully watched his face become red.

He stuttered slightly making Nitsu raise an eyebrow, when suddenly the door flew open to reveal Tsunade and the others again.

"What now?" Nitsu groaned as she waited for the woman to talk.

Tsunade shut the door once everyone was back in, "Nitsu, I've found out something interesting about your family history."

The girl blinked, "My family?"

The blonde woman nodded, "Yes. You see, that on your back isn't a seal. It's formed from your chakra."

"Really? But why do I have it on my back? And what's it for?" she asked trying not to jump up.

"I don't know why it's on your back. But what I do know is that that chakra on your back is far more powerful then the chakra you use normally," she grinned, "It kicks in when you need it the most and never drains away."

Nitsu tried reaching for her clothes, but was too far away, the pouted.

"Turn around you three," Sakura sighed as she handed Nitsu her clothes.

Quicker than ever, Nitsu was dressed and sighing happily, "Much better! You didn't know how much laying on my stomach was starting to get on my nerves. It's okay now."

Nitsu looked back over to Tsunade, "But what does it have to do with my family?"

Tsunade smiled, "That, Nitsu, is your Kekkei Genkai. I haven't found the exact name for it yet, but I will soon."

Nitsu and the others looked at eachother then shrugged.

As they were leaving, Nitsu suddenly started jumping around and giggling.

Naruto looked worriedly at Sasuke, who shrugged, then back to the jumping girl, "Why are you so hyper all of a sudden, Nitsu?"

She turned around and smiled holding up her fingers for a peace sign and grinned, "I have a Kekkei Genkai! Do you know how long I've wished for one?!"

Kakashi chuckled as Sakura walked up to Nitsu with a glare, "I'm still going to get you back for earlier."

Sasuke turned to Nitsu, "That's right, you said you'd tell me if I hid you."

"You hid her?!" Naruto and Sakura yelled.

He nodded then looked at Nitsu, "Well?"

She laughed nervously, "Earlier I had some cookies. Well, when Gaara came walking by, I offered him one."

"Oh no," Naruto groaned.

Nitsu continued, "He got really creepy with the big innocent eyes and asked for another. When I tried to get away, he chased me asking for another. That's when-"

"That's when she ran passed me, tossed the cookies to me and let Gaara chase me," Sakura cut her off.

Sasuke groaned as he glared, "I saved you from her because of that?!"

"Hey! You weren't really complaining!" Nitsu yelled then stopped. Kakashi and the others watched worriedly as Nitsu slowly looked at Sasuke with evil in her eyes. "AND ITS YOUR FAULT FOR THE RESULTS!" she screamed.

Sasuke blinked, "My arms buckled!"

"YOU'RE SUPPOSE TO BE THE 'UCHIHA PRODIGY'! HOW IN THE HELL, DO YOUR ARMS 'BUCKLE' HOLDING YOURSELF UP!" Nitsu yelled walking up to him.

"She's got you there Teme," Naruto grinned.

Sasuke glared at him as Nitsu walked slowly up to the raven.

"Hey Uchiha," she called.

"Wha-" he turned around only to have her fist make contact with his jaw. He flew back a few feet and landed hard on the ground as Nitsu glared down at him.

"Why did you do that?!" Sakura yelled as Sasuke stood up.

Nitsu growled, "That's what he gets for what you said earlier!"

The Uchiha glared hard at her and was about to leave when another fist caught him right under his right eye.

"What the hell?!" he yelled.

She looked at him with a look that could freeze anyone to the spot, "Don't you ever, EVER touch my back again!"

"Huh?" Kakashi blinked.

"Before you guys came back, he was tracing the markings on my back!" she yelled as she pointed to Sasuke, who was rubbing his now bruising cheek and jaw.

Naruto grinned, "Did he now?"

Sasuke glared at him as Nitsu nodded.

Kakashi chuckled, "Well, we have training tomorrow. Be at the bridge at eight in the morning." He suddenly poofed away as Naruto and Sakura groaned.

"Ne, Sasuke-kun? Would you want to go on a date with me?" Sakura asked with a sickeningly sweet voice.

He glared at her, "No."

"I'll go with you Sakura-chan!" Naruto yelled.

She scoffed at him, "I didn't ask you!"

Naruto pouted slightly then looked at Nitsu, "Do you wanna go eat ramen with me Nitsu?"

She shook her head, "I'll have to take a rain cheek Naruto. Right now, I need to go run scalding hot water over my back and rinse my mouth out."

Sakura's jaw dropped while Naruto burst out laughing. Sasuke glared at her, then turned to leave when someone spoke up.

"What's wrong Uchiha?" Nitsu yelled as she smirked at him.

He glared more, "Nothing, Otsuka."

She returned the glare, "I didn't know you'd get upset over that."

Sasuke turned around and walked up to her while the other two watched silently, he sneered as only a few inches were left between them. He looked down at her and hissed, "The only thing that upsets me is the fact that I have to see your face every day. You're more of a pain in the ass than the dobe over there!"

She hardened her glare, "Get off your high horse Uchiha before I knock your ass down a few levels. And speaking of faces, how is it that almost the whole female population of Konoha is in love with you? And what I don't understand is if they love you, and as long as I've known you, you've never looked at a girl unless you absolutely have to!"

He looked shocked for a minute when the words sunk into everyone's heads as Nitsu grinned evilly, "You wouldn't be gay by any chance…would you?"

Naruto choked out laughing as Sakura just stared at the two in shock while Sasuke's face flushed and Nitsu smirked.

The raven growled as Nitsu stepped back, still smirking at him. "I kissed you earlier," he glared with a slight smirk.

Nitsu gasped in fake shock, "Oh! Good cover."

Naruto lost his self-control and was on the ground rolling.

"I'll prove you wrong," he glared as she tried not to laugh.

"And how will you do that Uchiha?" she smirked at him again.

He smirked evilly and walked the last few steps, wrapping an arm around her waist and pulled Nitsu flush against him.

Naruto and Sakura stared wide-eyed as Nitsu looked disgusted and tried to get away. Sasuke leaned in closer and whispered in her ear softly, "You'll find out soon."

She scoffed as she tried to get away, "I'm not some stupid fangirl who'll go soft just from you touching me," she shook her head and looked at Naruto, "Poor boy must be in denial from realizing he swings for the other team."

Sakura glared at her for the fangirl comment while Naruto was holding his sides and crying from laughing so hard.

Sasuke held her tighter and said softly, "Real soon…Ni-tsu."

"Uchiha," she growled warningly, "Let go."

Before Sasuke could do anything a blue glow shown dimly through the back of Nitsu's shirt.

Suddenly, Sasuke was thrown a few feet away. He coughed and stood up to see Nitsu standing there panting hard with her fists clenched tightly. She glared at him darkly and growled, "Don't you ever fucking do that again Uchiha or I'll castrate you personally! And don't you dare call me by my first name!"

He stared in shock while she looked to Naruto, "Would you come do me a favor Naruto?"

The blonde nodded dumbly as she grinned and looked back to the raven, "Although, I do need to ask you how you get your hair and skin so soft."

Naruto grinned and walked with Nitsu to her house.

Sasuke glared at the retreating figures as he silently decided to follow, leaving Sakura confused and alone.
