Hello! I'm really sorry for making you all wait. Hope you enjoy this chapter and the more that will come! ^^

"First exercise, I want each and everyone of you to circulate your own chakra through your own body. I want every single one of you to control the flow through your entire chakra pathway system allowing all of you to be properly familiar with your tenketsu."

"I thought only people from the Hyuuga clan can do that?" Naruto asks, confused.

Rina shakes her head before correcting him, "The Hyuuga's special ability allows them to see the tenketsu of whoever they choose with their dojutsu however anybody; Byagukan or not are able to be familiar with their chakra system. It just takes concentration, practice and a little luck."

Suddenly, the tall kuniochi whips out a scroll and unwinds it to reveal a diagram of what a chakra pathway system should look like in a human ninja's body. She lays it on the ground and gestures her students to gather around and take a look .

"This is not drawn to scale but you can get the general idea of it."

Sasuke frowns hearing that because he was going to use his Sharingan to memorize it for future study. He looks it over again and sees something that startled him, the signature of the person who created the diagram.

Hyuuga Hisako

Sasuke blinked, an image of Hinata's mother flashing in his mind.

He knew Hinata's mother was once upon a time a great medical nin according to Hinata but he never expected this.

Rina speaks again, disrupting Sasuke's train of thought.

"Anyways this diagram is not particularly accurate because everybody is different. Everyone has the same number of tenketsu but not everyone's chakra points are in the same place. Some may be a little higher or lower than what the diagram indicates hence why only the Hyuuga clan are able to fully utilize this knowledge with their abilities."

"So how does this benefit us? We can't see our tenketsu." asks Sakura, not understanding where her sensei was getting at.

"No you can't see it but you can feel it and like I just said, all it takes is concentration. If you are sensitive enough to be able to pinpoint your tenketsu then congratulations, otherwise being able to properly flow your chakra throughout your entire system will be helpful regardless."

Naruto tilts his head, curious, "How?"

Rina opens her mouth to answer but Karin beats her to it, "Usually if you're in a cold climate, ninjas will use their chakra to circulate within their body to warm themselves up so that they do not catch pneumonia or frostbite."

Mitsukai smirks, impressed that Karin knew that and praised her ward for her accurate example before keeping the scroll aside. She claps her hands and instructs the genin to sit in a circle. She moves to sit beside Kakashi who closed his book, knowing fully well Rina would not take kindly if he did not participate.

"Erm Mitsukai-sensei?"

Rina turns to see it was Karin who seemed embarrassed to call her guardian by such an address causing the older female to smile and patiently asks what did Karin wish to ask.

"You told us you will tell us why we can't sit after exercise."

The 21-year old smiles wider before taking out her notebook and writing something out as she speaks, "While exercising, your heart is pumping hard and sending blood to the working muscles in your arms and legs. If you stop and sit down your heart will quickly slow down, leaving lots of blood in the particular area. Some people may actually faint from that if they are not careful. Thus it is recommended that before and after exercise, you stretch to ensure your muscles are properly warm and ready where you can also benefit from increased blood circulation."

Naruto's eyes widen after hearing the whole explanation, "Cooool! So that's why you always make me and Karin stretch all the time?"

She winks at him in response causing Naruto to grin before passing over a piece of paper she tore from her notebook to pass to Karin who looks it over only to recognize a few familiar medical terms like, 'aorta' and 'cardiovascular'.

"That, is for your own benefit. That is a lengthier version of the answer to your question however his better explains what actually happens within the body before and after exercise by scientific standard. I hope this helps in your medical training."

Karin smiles fondly at the kind gesture before lifting her face to sincerely thank her guardian. Rina merely waves her hand modestly.

"Now, all of you concentrate, I am officially starting the first exercise."

She watches as all of them get into a meditative position and proceeds to speak in a voice clear and loud enough for all of them to hear but in a pleasant tone that calms everyone.

"Just relax and focus on the flow of your chakra. Close your eyes and focus on the warmth that is within you."

Rina watched as one by one, her students closed their eyes, she turned to Kakashi who was also studying them carefully. She gently tapped his shoulder and mouthed to him to use his Sharingan. Once he nodded his head to confirm his understanding, the experienced kuniochi stood up and slowly made her way walking around the circle. Sasuke was the first to get her attention.

"If any of you are feeling numbness in a certain part of your body means that you are not focusing your chakra enough on that particular part. Keep in mind that you must flow your chakra throughout your system."

Sasuke frowned, wondering how she knew that he was feeling numb in his left leg in that particular moment but guessed it was probably because he was fidgeting in his left side to get the feeling back. He pushes the thought aside for now and instead focused on the exercise.

Meanwhile, Kakashi was impressed by the control Karin and Sakura displayed he's observed however he mentally reminded himself that Sakura had small reserves to begin with hence control would come naturally for her but Karin on the other hand has a rather large chakra reserve which is almost as big as Sasuke's hence larger than any average genin. He concluded that out of the four, Karin probably had the best chakra control.

"If any of you are sweating profusely and feeling hot all over, it means you are pumping too much chakra and that you have no control. You need to reign it in."

Kakashi turns and sees Rina standing in front of a frustrated looking Naruto.

"I-I c-can't..."

"Yes you can Naruto come on."

The grey-haired jounin watches with his Sharingan as Naruto's chakra flares up almost scalding Karin and Sasuke who swerved to the side from the heat of the chakra. Sasuke calls him an idiot which only agitated the blonde more. Naruto then opens his eyes suddenly, panting as if he was out of breath. Sakura opens her eyes too and watches in shock as for some reason, Naruto looked like he was hyperventilating.

"H-help.."

Rina crouches down calmly, she sees the terrified look in her ward's eyes and her heart was telling her to snap him out of it but her brain was telling her that she had to make him try harder.

"Naruto, come on don't stop trying. You can do this."

"I c-can't!"

Rina uses her arm to shield her face and bends backward from the chakra that flares her way but it manages to lick at the side of her hand causing a loud hiss to escape her pink lips. She looks up and sees Naruto, disgruntled as he had obviously caught sight of his chakra hurting his guardian but due to his added stress, Naruto's chakra flares some more that it made Karin and Sasuke move closer to Kakashi and Sakura respectively.

"M-mitsu-"

Rina closes her eyes, realizing that Naruto really couldn't do it hence there was no helping it; she must help him now. The rest of Team 7 watches as the green-haired special jounin rest both palms on her lap before straightening her back. She takes a deep breath and she sings sweetly, slowly raising her good palm to her diaphragm to control her breathing as she sang..

Much as you blame yourself,

You can't be blamed for the way that you feel

Had no example of a love that was even remotely real

How can you understand something that you never had?

If you let me, I can help you out with all of that

Slowly Naruto regain his breathing, the tension almost disappearing in his shoulders with each continued word Rina sang soulfully. He meets eyes with her when she opens hers; amethyst meeting cerulean blue. Kakashi breathes a sigh of relief as Naruto's chakra simmered down bit by bit.

Let me love you

And I will love you

Until you learn to love yourself

Let me love you

I know your trouble

Don't be afraid, oh, I can help

Let me love you

And I will love you

Until you learn to love yourself

Let me love you

A heart of numbness gets brought to life

I'll take you there

Slowly Rina extends her hand towards Naruto as she finishes and the blonde takes it gratefully, completely mesmerized. Karin was the first to approach and moved to sit by her cousin who was now completely mellowed. She squeezes his arm and Naruto turns to see her worried expression. He apologizes softly as the rest of the team comes toward them.

"Naruto."

The blonde turns his head and Rina looks at him carefully as she speaks, "Naruto what you have displayed for me just now is a clear indication that your chakra control is absolutely dreadful."

The blonde's face colored with embarrassment at the critique immediately, he tries to look down in shame but Rina lifts his face by the chin so that he maintained eye contact with her.

"Naruto, you and I are more than well aware that you have been gifted with extremely large chakra reserves practically monstrous in size and nature but you can never be able to make use of this if your chakra control is not up to standard."

Naruto, like Karin and Kakashi did not miss the fact that she used the word 'monstrous' but wisely kept their mouths shut as Rina continued.

"The leaf exercise isn't doing shit for you. Pass me your notepad for a bit and I will jot down some exercises you can do that will improve your chakra control accordingly."

Naruto did not hesitate in the least; he passes to her the notebook and watches her write everything down in a fast pace without a word.

Sakura however, spoke up suddenly,; hearing all this quietly, "If Naruto can't do the simplest chakra control exercise how can any of your exercises be any better for him?"

Unperturbed, Rina responds as she continues, "Like I said earlier, Naruto has huge chakra reserves. The leaf exercise is only applicable to academy students and genin due to the fact that they would normally have low reserves. Naruto needs exercises with a more aggressive structure that is suited to his peculiar large chakra."

Sakura says nothing, unable to argue with a straightforward explanation like that. She watches as Rina returns Naruto's note book back to him. The blonde mentally reads them to the best of his ability, completely oblivious to the fact that Karin had leaned over to read them as well.

"Next exercise children. Come on, move it!"

The remaining genin scramble to their places at her loud, commanding tone. The clap of her hands bringing them back to attention. Before she begins, Rina rearranges the seating and moves Karin to sit next to Sasuke and Naruto in between Kakashi and herself with Karin beside her.

"Alright, this next exercise requires you all to work together and flow your chakra into the next person that you're holding hands with on your right. Now-"

"HOLDING HANDS?!"

Sakura squeals in delight because Sasuke was on her left which meant she was going to feel his chakra directly. The Uchiha groans in disdain but knew fully well that Rina would not let him out of it so he reluctantly moves to hold Sakura's hand causing the pinkette to blush furiously at the contact.

"As I was saying, this exercise will help us see how much chakra you can take and how much you can really control. Now in order to do this everyone, you will all hold hands and on the count of three, focus on your chakra to flow into the palm of the person on your right and absorb the chakra of the person on your left."

"Ow!"

Rina's eyes shoot open and sees Sakura clutching her hand in her wrist with a pained expression on her face and immediately she turned to Sasuke who looked confused.

"Sasuke, putting too much chakra can burn someone. Sakura has small reserves so the amount of chakra she can absorb can only be so much. Be gentle please."

The avenger deadpans but grunts a response to indicate his understanding before gently taking Sakura's hand again causing Rina to smile softly before starting the count.

"3...2...1."

Kakashi watches everyone during the exercise but Naruto once again catches his eye; Naruto was sweating with an anxious expression on his face and Rina was squeezing his hand everyone so often. It was then he realizes that Naruto was probably burning her with his chakra and Rina was quietly trying to remind him to ease up. It made sense why she purposely rearranged the seating, she did not want the other genin to be burned by Naruto's chakra.

Kakashi, who had done this exercise in ANBU before decides to help Rina out to get the exercise going, "Everyone, please tell me what each of you are feeling."

"Stressed." Naruto mutters, barely audible.

"Warm" Karin announces clearly.

Sasuke answers next with a peaceful expression on her face, "Soothing"

"Hot"

Kakashi turns, hearing Sakura's answer and realizes that as much as Sasuke was trying to control his chakra, it was still too much for Sakura to properly reign in and control. Rina counts down, seeing this happening as well and everyone breathed a huge sigh of relief once they released each other's hands.

The green haired kuniochi pulls a tiny bottle from her pouch and pours the medicinal cream onto her hands; Naruto watches in amazement as the burnt marks he gave her disappears almost instantly.

"Wow, that's so cool!"

Rina says nothing as she rubs her hands and wrists carefully before closing the bottle to put it away again and slowly flexing her fingers. She made a mental note to thank her goddaughter for the medicine later.

"Mitsukai-sensei, may I have some too?"

Rina raises her chin, just enough to see Sakura with small circular burn on her open palm so she motions for her to come forward. The pinkette does so but stiffens immediately when her new sensei gently pours a bit of the cream on her hand and freezes in shock as Rina rubs it on her palm gently without instruction. Sakura blushed at the soothing warmth of healing chakra slowly absorbed through her skin surprised by the kind gesture. Once the mark disappeared, Rina passes Sakura two pieces of paper before telling her to go back to her seat and pass one of the papers to Sasuke to use; Sakura nods and follows instructions accordingly after mumbling a soft thank you and giving the green-haired jounin a little bow in respect.

"Now then I am passing a piece of chakra paper to each of you to use to find out what nature affinity you are. Just put in a little chakra and it will react accordingly."

"Mitsukai-sensei, I already know what their elements are."

Kakashi blinks, unsure if he heard right but he asks Karin how, only for her to respond with a mere smirk. Karin smugly points to each member of the team, announcing their element with confidence.

"Mitsukai-sensei is Water type. Naruto is Wind. Sasuke and Sakura is Fire while you are Lightning type and I am Earth type."

Rina tilts her head, intrigued, "So that is how you got the idea to prompt me to use the river that time because you saw I was water-natured somehow?"

The redhead nods, pleased with herself after explaining that she has superior chakra sensor abilities hence how she is able to see who has what affinity however, much to her surprise, Rina says she still wants the others to use paper.

Naruto, extremely curious was the first to try but his chakra sends the paper to fly above his head but before he could stand up to try and catch it, Rina holds him back and points above it.

"Naruto, you can see your paper has split into half. What does that tell you?"

"Erm, I don't know?"

Rina sighs, rubbing her forehead but she takes a deep breath and explains to him that it shows that his chakra is wind which gets a gleeful 'awesome' in return.

Sakura tries next and her paper turns to ash so Rina informs her that she is indeed Fire-natured. Kakashi and Rina goes next for demonstration and his paper wrinkles in his hand defining his affinity as Lightning-type while Rina confirms her affinity as water-natured when her paper becomes damp in her palm. Karin then finally uses her chakra paper which turns into dirt and crumbled in her hand defining her as Earth-type.

"Then what am I?"

Everyone turns to look at frustrated Sasuke with ash in his hand. Karin sees this and rolls her eyes, "Clearly you are fire-natured like I sensed you to be."

"My paper wrinkled like Kakashi's before it burned FourEyes."

Rina flings another chakra paper in Sasuke's way without notice and orders him to try again and just like he said, the paper wrinkles in his palm before burning which just confirmed one thing.

Sasuke was dual natured; lightning and fire which was rare for any shinobi. Sasuke smirks triumphantly hearing this while Naruto looked a little jealous but Karin on the other hand was pissed.

"He cannot be sensei! I sensed him to be fire!"

Rina shakes her head, answering calmly, "Fire has been Sasuke's predominant element all this while. Majority of his arsenal includes fire release techniques. It is unsurprising that the chakra Sasuke emits is more like fire."

Karin frowns deeply as Rina continues, "Now obviously the reason why I am doing this is because I plan for all of you to delve into elemental ninjutsu training."

For the first time since Sasuke returned to the village in a mangled heap, he smiles; not smirk but smiles and listens intently as Rina explains.

"Kakashi will be the teacher in charge of this exercise due to this vast experience in element release techniques. Therefore-"

"I thought there never has been anybody that mastered all 5 elements before?" Sakura asks, interrupting Rina but before she could turn to look at Kakashi, a shuriken cuts her cheek and she turns to see Rina glaring at her intensely, "Sakura, I hate being interrupted and you have interrupted me 4 times already so interrupt me again and you will see what I will do to you. Understand?"

Sakura gulps and Rina answers nonchalantly before straightening her posture, "Kakashi is known as Thousand Eye Kakashi due to the fact he has copied many techniques with his Sharingan and he has release techniques of all the elements."

Kakashi shrugs modestly before adding on, "The only elements I have mastered is lightning, fire, earth and water but wind is more difficult. Only the people who have the affinity are able to properly master it."

Naruto cheers, saying he has the coolest element while Sasuke rolls his eyes. Kakashi goes on to say he will train everyone the best he can on their affinity. However if any one of them wants to partake in ninjutsu of a different element, he suggests mastering the element that have an affinity for first beforehand. Karin asks why and Kakashi explains that molding your chakra from an element you are already used to into some other element will take training and a lot of hard work. He does not want them to be discouraged from ninjutsu by trying things too early but makes it clear that Sasuke will have a hard road ahead of him as he has two affinities and focusing on lightning after training so long with fire will be hard.

Rina claps her hands once Kakashi finishes, "Now, as you are all aware this will be what happens. Each of you will do research on your affinity and the techniques you can use. You are to come in every week with knowledge of 2 or more release techniques of your affinity. One must be performed effectively and accurately for us to see your progress while the other technique is something I want you to inquire Kakashi about because you have trouble with it. Bring along your guidebook, in case you have extra time on your hands. Elemental training will be conducted on the first of your four training days. Got it?"

"4?" Sakura repeats. "I'm pretty sure our training was only three times a week."

"The other teams in your cohort have 4 team training days hence why I am changing it so that all of you have four days like everybody else."

Sasuke frowns, confused," Why were we only 3 days? "

"Because aside from training you kids, the Hokage always assigned me many missions on the side." Kakashi admits finally.

The genin blinks, confused by this new revelation until Sakura who got over it rather quickly suddenly speaks up.

"Sensei, four days is too much. I have parents, a family business to help out and chores at home. Can't we just remain as 3 days? Everybody else has it easy because they live alone but I have stuff to do."

Almost immediately, everyone else turned to look at Sakura carefully, wondering if she was actually serious. Rina on the other hand was calm.

"Yamanaka Ino is in the same situation as you but she does not complain so why are you?"

"I am not complaining! I am just saying! "

Rina waves her hand dismissively, not in the mood to get into it and promptly changes the subject, "It is rather interesting that this entire team has all 5 elements at our disposal."

Sasuke deadpans, confused until he realizes what she meant; he and Sakura had fire, Rina was water, Naruto was wind, Kakashi was lightning while Karin was earth. The 5 elements were indeed at their disposal.

"Ok everyone stand up and let's do some stretching and a quick full body workout. Before I end this session, I want everyone to be able to go home with sweat on their skin."

Kakashi chuckles, realizing what she is upto. He stands with the rest of them and smirks when Rina calls Sakura to come forward and lead the warm ups.

"Ehhh no way! It's too embarrassing!"

"What's embarrassing about warms up?" asks Rina, puzzled.

"I don't wanna stand in front of everyone and instruct them to do stuff!"

Kakashi chuckles, hearing that so he points out that Sakura was always the bossy one in the group much to the pinkette's displeasure.

"Sakura you know the Academy stretches by heart hence why I want you to do them now come on up."

Sakura sighs heavily before moving to stand beside her sensei and Rina watches gleefully as the team follows her lead and even more so when she sees Kakashi doing them from behind.

The young sensei moved to where Kakashi was and stretched by his side, speaking to him in whispers.

"I'm surprised you're doing it along with them."

"Well your hell full body workouts would be good for me. I have been slacking lately. I could use a good sweat."

"Hn, getting soft are you Tomoe?"

"Not at all beautiful."

Rina swats his arm playfully before clapping her hands to get everyone's attention as she moved back to the front.

"Now then, let's get moving!"

Sakurai moves to stand in between Sasuke and Naruto but when she turns back to the front, she pales instantly at the devilish smirk on the gorgeous woman's face hence she came to one conclusion.

Mashiro Rina was somebody not to antagonize .

Hope you liked the chapter! Please rate and review! Thanks! ^^
