Author's note:

I don't own Naruto.

Well, here it is then:

Chapter 5

The twins had gotten to leap late the night before, so the mad rush about the apartment was not entirely surprising. Despite the lack of time, Kitsumi managed to make a portable breakfast for the two of them. Unfortunately, her hurried choice of clothes was less successful. while she managed to avoid her brother's clothes, the blue skirt she found would not work well for training, although it happened to match the shirt she picked out. Regardless, there was not time to worry, as the pair ran towards the academy.

Their running, although not the leaps and bounds of a real ninja, had quickened significantly: almost twice as fast as when they began the academy. In fact, the six months at the academy had done quite a bit to them. The children seemed so different that they would barely recognize their past selves. Naruto had grown two inches, which brought him close to four feet. All trace of baby fat was gone, replaced by muscle that seemed slightly out of place on his young body. Kitsumi had also grown: almost an inch and a half. She was no longer taller than her brother, but was much thinner. Her muscles, while as strong as Naruto's, were not as visible. She had also chosen to wear her hair in pig tails. She liked it long, but if she wore it in a ponytail, she would look like a member of the Sasuke fan club.

Somehow, the pair managed to arrive on time, and took their seats. Only ten seconds later, Iruka walks into the class to begin the lesson.

"OK class, today we are going to learn about chakra. Does anybody know what chakra is?" As usual, the lesson began with a question, but this time, the question was something they had not yet covered.

"Umm... Chakra is... life energy... that flows... through your body." Everyone turned, slightly startled that Hinata had said something. They recovered quickly as Iruka began to speak again.

"Very good Hinata. Now, does anyone know what ninjutsu is?" Iruka continued.

"Ninjutsu is the art of channeling one's chakra through hand signs to create a variety of effects in the world" Sasuke answered methodically.

"Very good Sasuke. Where did you read that?"

"Brother told me."

"I see. Now, today's lesson concerns chakra. Now, because you all have never used chakra before, I am going to teach you how to find it within you. Now, during this exercise, we need space, so everyone follow me." Iruka finished his speech, and began to lead the kids to an empty building kept for this purpose. When they arrived, Iruka turned to address them again.

"Alright, now that we're here, I want you to form a circle, and sit down." They all sat in something that was close to a circle and Iruka continued, "Now, everybody close your eyes, hold out your hands, and think of a blue substance running through your body like blood. Once you get a good picture, I want you to imagine it concentrating in your hands. OK?" The class furrowed their eyes in concentration, and soon Iruka went around to check their progress.

Naruto and Kitsumi were sitting next to eachother. They were attempting to perform the excersize, but every time they got the blue stuff to go to their hand, it would all drain away somewhere. However, Naruto eventually gave up, deciding to check and see how the others were doing. He noticed that Sasuke's hand was glowing faintly blue, and also Shino's. He decided to try harder, and went back to imagining his own blue liquid, only to discover that it wasn't there.

Meanwhile, Kitsumi had finally met with some small success. She had successfully gotten that evasive blue liquid to gather in her hand. She felt a pull from somewhere within her mind, almost like when she visited the sight of sealing, when something interrupted her.

"Kitsumi. Very good." Iruka whispered extracting her from her trance. She opened her eyes to see that the others were staring at her. Well, not Naruto, he was busily concentrating.

"Did you see what you did Kitsumi?" Ino whispered from next to her.

"No, why? Was it cool or something?" she whispered back.

"Yeah, it was amazing. Your hand was glowing really brightly, and it was almost smoking. How did you do it?" Ino replied.

"Well, its just like going to the... I mean, its just like Iruka says. You just imagine the blue stuff, and eventually it comes to life. Then all you do is think it to your hand." She had almost let out the big secret. That wouldn't have been good.

"Whoa, look at Naruto." Ino suddenly elbowed Kitsumi and pointed. "That's what it looked like." Kitsumi turned to see Naruto's hand glowing blue around the edges, and with a small amount of blue mist falling off his hand.

"Whoa, I did that?" Kitsumi wondered aloud.

"Very good Naruto." Iruka awoke Naruto in the same manner. He looked slightly puzzled. Academy level students shouldn't have enough chakra that it begins to leak out. He would have to look into the incident later.

After that, the children went back to trying to focus their chakra into their hands. By the end of the day, most of them could make their hands turn slightly blue, but none could match the brightness of Naruto and Kitsumi. Although, neither could repeat the success, and they too had to work until the end to make their hands glow slightly blue again.

When they returned to their appartment after school, Kitsumi decided to continue practicing until it was time to cook. Naruto however, snuck out of the house to work on his surprise.

Later, he returned to find her with her hand and arm glowing, as brightly as in class, and shook her lightly.

"Hey, sis. When did you get so good at it?"

"Huh, I don't know, ever since I've been home its been easier. My chakra doesn't run away anymore." She stirred out of the trance and responded.

"Huh, let me try" and Naruto slipped into his own trance. Kitsumi realized that she had to make food for dinner and tomorrow, and headed into the kitchen.

When she returned a later, she saw him as he had seen her earlier: with his arm and hand glowing brightly.

"Hey, brother, did you see what I meant?" She shook him lightly.

"Yeah, its a lot easier when we're at home. I wonder why that is."

"Me too. You know what this reminds me of?"

"What?"

"When we went to the site of sealing. Remember?"

"Yeah, maybe we should practice that at home, and the chakra in school."

"Thats a good idea. I mean, they are kind of similar, so if we get better at one, we should improve the other. And, we can't let one skill get past the other right? So lets go." They slipped back into the trance, but this time, went to the site.

"Hey, its you two." The loud voice sounded from within the cage. "What have you been doing lately? There's been some blue stuff flying around in here."

"We've been practicing our chakra." Kitsumi replied.

"Oh, you think you can use chakra now?" The beast began to laugh.

"What? We've been training really hard!" Naruto retorted defensively.

"Oh, its just that you two don't have very much chakra." The laughter subsided.

"Well, you can expect to see us here a lot more often now, cause we decided to practice this again in addition to chakra." Naruto was miffed by the fox's comment.

"Anyway, we need to get to sleep, so we'll be back in a bit." Kitsumi said, as she and Naruto returned to their bodies, and went to sleep, returning to the site of sealing.

They began to go through their warm ups from class, while the fox watched with amusement.

"Why are you stretching?" It asked after a few moments.

"So we don't injure ourselves when we practice. Iruka-sensei says to always stretch before practice." Kitsumi replied.

"But, how do I say this... Your in your mind. Why do you think stretching your 'body' will make a difference?" The demon almost laughed.

"It can't hurt." and with that Kitsumi and Naruto went back to training.
