Aika groaned and opened her eyes, she was in an unfamiliar room. She sat up quickly looking panicked.

"Aika you're awake!" she heard her idiotic big brother shout and hug her immediately

"Naruto" Aika looks at him "..where are we?"

"Oh we're at old man Tazuna's house" Naruto tells her as he lets her go "How could you use your weird fire ability again, we've talked about this"

"Idiot I told you it's called a kekkei genkai" Sasuke says as he walks into the room

"Whatever, I still told her not to use it" Naruto crosses his arms

"I told you I can't control it" Aika pouts "I don't even understand how to use it"

"Well it was useful" Sasuke sits on the other side of her "it seems your special fire kekkei genkai was stronger then Zabuza's clones"

"really?" Aika smiles "that's good"

"It would be better if we knew what it was" Naruto sighs "I may not understand a lot of things but not even Sasuke knows what it is"

"the only kekkei genkai I know well is the sharingan" Sasuke tells him annoyed "it's from my clan, Aika's is different, her eyes just glow red. Their's no way for me to identify it"

"maybe Kakashi sensei knows" Aika suggests

"we'll ask him later, he just woke up and asked for us to see him" Sasuke tells them

"Alright" Aika stands up

Naruto stands up as well, Sasuke stands up and picks up Aika.

"hey what are you doing?!" Naruto shouts

"I'm carrying her idiot" Sasuke tells him "she's weak and their's no way I'd let you carry her"

"I can carry my little sister just fine!" Naruto shouts

"guys stop fighting" Aika whines

The three walk into where Kakashi's staying, Sakura was already there kneeling next to him.

"Good to see you're awake Aika" Kakashi smiles "I was worried you overdid it"

"I'm glad to see you're awake as well Sensei" Aika says happily

Sasuke sits Aika down next to him and they all look at Kakashi.

"Listen Sensei" Sakura began "Your Sharingan is amazing and everything but if it puts that much strain on you, maybe it's not worth it."

"Don't worry we'll be safe for a while" Kakashi tells her

"Right but what about that boy in the mask?" Sakura continued to question

"what boy?" Aika asks confused

"you were unconscious" Sasuke tells her "just listen"

"He's from the elite tracking unit from the village hidden in the mist. Those masks are only worn by the most elite Shinobi" Kakashi tells them

"Oh I know" Aika speaks "The ANBU Black Ops also known as the Infernal Squad, destroy all traces of a rogue ninja's corpse. The Shinobi's body contains many secrets, ninjutsu, chakra. These are the secrets of his village. If his enemies find him, his village will be in grave danger. For example. If Kakashi-Sensei was to die by the hands of an enemy, he'll try to analyze his Sharingan. In the worse case, his entire jutsu could be stolen and used against our home village. It is the sacred duty of the tracker to prevent this and keep the village's secrets safe. If a ninja betrays his village, trackers hunt him down and eliminate him and obliterate any trace of his existence. That's their specialty"

"Yes" Kakashi nods "Tracker Ninja deal with the body quickly so there's no room for error. But remember what that kid did to Zabuza's body?"

"We don't know what he did. I guess he took it away somewhere" Sakura replies

"Yeah but why? He should of worked on Zabuza on the spot. Did you see the weapons he used?" Kakashi questions

"They were throwing needles." Sasuke answered. He then thought for a moment. His eyes widened when he hit realization. "...No way."

"Exactly.. none of it adds up" Kakashi says

"What are you jabbering about? You demolished that assassin." Tazuna speaks

"Here's the truth...Zabuza's still alive..." Kakashi tells them

Tazuna's, Sakura's and Naruto's mouths dropped open.

"Kakashi-Sensei, you checked him yourself that his heart stopped!" Sakura shouts in disbelief

"His heart did stop but that was a temporally state to simulate death" Kakashi replies

"Well according to what I hear, the weapons that the tracker used are called Senbon. They can pierce deeply but rarely kill unless they hit a vital organ" Aika explains "They are modified for needles used in medical treatments like acupuncture. Trackers are trained to know every detail of the human body, causing the heart to stop temporally while keeping the body alive is a easy matter for them. First.. you guys said the boy used senbon which have a precise effect but are rarely fatal. Then, he carried the body away. From these factors, we can conclude that the tracker wasn't trying to destroy Zabuza, he was trying to save him"

"Come on kid, you're over thinking it." Tazuna says

"No way" Aika shakes her head "I may be bad at Jutsu's, but when it comes to the books I've memorized every detail" she looks at Naruto who looks excited "big brother you're unbelievable"

"I'll have to train you guys" Kakashi says

"Hold on! A little last minute training won't make us strong enough to fight Zabuza! You could barely defeat him with your Sharingan! We have to be reasonable about this!" Sakura shouts sounding panicked

"Sakura, I was able to stop Zabuza because you all helped me. You've grown.. Naruto; you've grown the most" Kakashi praises

"alright big brother" Aika hugs him happily

"So you two noticed? Now things will get better, believe it!" Naruto shouts

"I don't believe it!" a voice shouts annoyed, they all turned to see the source of the voice; a little boy

"Inari, where have you been?" Tazuna asks

"You're back Grandpa!" Inari happily ran into his arms

"Inari, that was very rude! These ninja helped your Grandpa and brought him here safely!" Tsunami scolds

"Mom, don't you see these people are going to die! Gato and his men will come back and find them and wipe them out" Inari argues

"w-wipe us out" Aika mumbles

Sasuke pats her head comfortingly

"What did you say?! Listen up, do you know what a super ninja is?! That's me only a lot better. I'm going to be Hokage! This Gato is no match for a real hero like me!" Naruto shouts

"There's no such thing as a hero. You're just full of stupid ideas." Inari crosses his arms

"What'd you say?!" Naruto headed towards him but Aika wraps her arms around him

"Big brother don't fight with him, he's just a kid" Aika says

"If you want to stay alive, you should go back from where you came from" With that, Inari left.

Aika lets go of Naruto and stares at the door.

"Training starts now" Kakashi says as they stood in the forest "First, we will begin with a review of chakra. Understanding chakra is essential."

"We know that already" Naruto complains "A long time ago we learned about..Catra"

Sakura and Sasuke look annoyed at Naruto while Aika giggles.

"Chakra not catra" Aika tells him

"Yeah that's what I said" Naruto replies

"Sakura, Aika, please explain" Kakashi sighs

"Sure thing" "no problem"

Sakura starts "Chakra is essential to even the most basic jutsu. Through various methods, the most common of which is hand seals, chakra can be controlled and manipulated to create an effect that would not be possible otherwise, such as walking on water, exhaling fire, or creating illusions"

"Chakra is ordinarily not visible to the unaided eye unless it is highly concentrated or manifested in large amounts. This is rarely seen due to the restrictions of eight specific tenketsu known as the Eight Gates, which limit the amount of chakra an individual can release at a single given time" Aika finishes

"Right" Kakashi says

"So, what's the point?" Naruto questions annoyed

"I actually agree with this idiot for once" Sasuke crosses his arms "we need to be training to defeat Zabuza, not having a history lesson"

"Because chakra takes time and a great deal of training to gradually build up, the key to its use is not actually having large amounts of chakra but instead being able to sufficiently control and conserve it" Kakashi explains "This is called chakra control. In order to have good chakra control, a ninja should only mould as much chakra as they need to perform a given ability"

"oh, If a ninja moulds more chakra than is needed, the excess chakra is wasted and they will tire out faster from its loss. If they don't mould enough chakra, a technique will not be performed effectively, if at all, likely creating problems in a combat situation. Because chakra consists in part of spiritual energy, the user is more easily able to mould the correct amount of chakra by remaining calm and focused" Aika smiles

"right you are" Kakashi agrees "you learn fast"

"...so?" Naruto looks confused

"This is your lesson" Kakashi looks at them "you will.. climb a tree"

The four look at him doumbfounded.

"but their's one rule, no hands" Kakashi adds

"no hands!" Aika shouts

"mhm" Kakashi nods

"You're kidding right?" Sakura asks

"Am I? Let's see" Kakashi focuses his chakra to his feet and started walking up the tree. "Focus your chakra to the soles of your feet and use it to connect it to the tree."

"oh no" Aika sulks "I had the worst chakra control of the class"

"Wait a minute.." Sakura says "How does that help us fight Zabuza?"

"Let me get this through your dense head. It helps you draw a precise amount of chakra to a precise point of your body. If you can master this, you can master any jutsu theoretically. This also helps you maintain your chakra levels" Kakashi threw kunai to their feet "Use the kunai knives to mark the highest point you can climb without using your hands. Then try to get past that part the next time and the next. Run at the tree to get started"

The group picked up the kunai

"uh, sensei" Aika looks at him

"Go" Kakashi instructs, ignoring her

The group charge at their trees. Aika put one foot on the tree and immediately fell onto her back. Naruto made it a bit up the tree, Sasuke made it about the same as him before they both fell and landed on their feet.

"This is fun!" they look up and saw Sakura sitting on a branch

"How did you-" Naruto gaped

"Well looks like Sakura has the most advanced chakra control. Well done" Kakashi praises then glances at the boys "We spoke about someone becoming Hokage didn't we? Seems like Sakura has the best chance at that. And as for the Uchiha Clan, maybe not so great after all."

The boys look annoyed and seem more motivated. As the boys start up again, Aika sighs and stays laying on her back, she just stares up at the tree. Aika soon sees Kakashi standing next to her, peering down at her.

"Hey sensei" Aika greets lazily

"What are you doing Aika?" Kakashi sighs

"Just, watching the tree" Aika replies

"You're supposed to be climbing the tree" Kakashi says

"Yeah.. but I won't be able to" Aika sits up

"What makes you think that?" Kakashi asks

"Well I took one step and immediately fell" Aika chuckles "with my chakra control I won't be able to climb it"

"Aika" Kakashi sighs and bends down next to her "You passed out after using your jutsu while fighting Zabuza because of your weak chakra control. If you work on it you'll be able to do a lot more during fights"

"I don't need to, Naruto's got it" Aika smiles

"you have no motivation to fight at all, the only time you fought seriously" realization hit Kakashi "...was when someone.. was in danger"

"hm?" Aika tilts her head

"Aika, why did you fight Zabuza?" Kakashi asks

"huh?" Aika looks confused "why did I fight him? To save you of course Sensei, because you're like family"

"And what about those brothers after we left the village?" Kakashi questions

"well Naruto froze up and Sasuke saved him leaving an opening for the other brother to attack" Aika explained "Sakura and Old man Tazuna could've been killed if I didn't do anything"

'her only motivation for doing anything is to protect people' Kakashi thinks

"Aika in the future how are you going to face a stronger enemy?" Kakashi asks

"What would I do that for?" Aika questions "the show's called Naruto, not Aika"

"What?" Kakashi looks confused

"don't mind me" Aika lays back down "just casually breaking the fourth wall"

"Aika, you have to do the exercise" Kakashi says

Aika sighs and stands up "yeah yeah"

Kakashi stands back and watches as Naruto and Sasuke continuously go up the tree as Aika can't even get up one foot.

"Oh boy" Kakashi rubs the back of his neck "what am I going to do with this girl?"

At dinner, Naruto and Sasuke stuffed their faces. They were pigging out like there was no tomorrow.

"I want more!" They held up their bowels, glaring at each other

A few seconds later, they turned their heads away from the table, puking out everything from their stomachs.

"Don't eat so much if you're going to puke it out!" Sakura shouts annoyed

"I have to eat" Sasuke says

"And I have to eat more than him" Naruto says "Its the only possible way I'll get strong enough to beat him"

"Tsunami thank you for the food" Aika stands up and bows to her

"oh of course" Tsunami smiles "no problem"

"I'll be back later" Aika says to Kakashi before running out of the house

"hm?" Kakashi raises his eyebrow

Aika kicks the tree in anger "AH, why can't I do it! Stupid tree!"

Kakashi stands behind a tree a bit away from her watching 'so she does care'
