Naruto: Chakra System

In the classroom, all 27 Genin waited eagerly, as their shinobi lives were set to officially begin from today. From the staff room, each Jōnin went to the classroom one by one, announced the names of the Genin who would be under them, and then took them to a separate training ground.

With now Kurenai's turn, now 7 Jōnin had already left, leaving only Asuma and Kakashi in the staff room. Asuma got up from his chair and said, "Now I should go, and Kakashi, don't make your team wait too long, okay?"

Kakashi waved his hand, remaining seated with his legs resting on the table, his eye closed as if he were sleeping. Once Asuma left, leaving him alone in the room, he slowly opened his visible right eye and summoned, "System Panel!" The transparent status screen appeared before him, staring back at him.

[Host: Kakashi Hatake]

[Chakra Pool: 258,425/265,260]

[Chakra Control: 89/100]

[Chakra Level: Elite Jōnin]

[Chakra Affinity: All]

[Chakra Growth: +20,000 per day]

Kakashi curiously glanced at his stats. "Today I've reached over 250,000 in my chakra reserves, and yet it's still only Elite Jōnin. Just what is the actual difference between a Jōnin and Kage-level chakra reserves?"

He mused, "Doesn't that also mean my initial chakra reserves, despite being good, were very low compared to even a low-level Kage? Man, but whatever, my chakra reserves are more than double my initial amount, and chakra drainage from my Mangekyō Sharingan is no longer any major problem."

He then made his status screen vanish and put his hands behind his head, closing his eye once again for a short nap. After ten minutes, he got up and decided to go and meet his new Genin squad.

He thought, 'I should try to make them focus on their main strengths, like Naruto's control over his chakra and the Nine-Tail's chakra, Sasuke on his Ninjutsu and Genjutsu, and Sakura on Medical Ninjutsu.'

He didn't want to waste time as the original Kakashi did in the anime, especially not when he knew their strengths and weaknesses.

"But still," Kakashi muttered while walking casually towards the classroom, "The bell test is necessary, but this time it should only be to ensure they take me very seriously, especially Sasuke. I don't want him to go to Orochimaru and then Itachi for revenge and all that."

Kakashi reached the classroom and saw that Naruto's duster prank wasn't set up. He thought, 'Maybe because I'm not very late, and they haven't been waiting for me for hours.'

Creak!

The door opened slowly with a soft sound, and Kakashi entered the classroom. He saw Naruto pacing around the bulletin board in the classroom.

Naruto wore his usual orange and blue jacket with a white collar, a white swirl with a tassel on the left side, and a red Uzumaki crest on the back. He also wore orange pants with a shuriken holster on his right knee, blue sandals, and the Konoha forehead protector given to him by Iruka after graduating from the ninja academy that night.

He was clearly quite impatient, even though Kakashi wasn't hours late like in the anime. Just to the side, Sakura sat casually with her arms bent at the elbows, her forearms and hands resting on the desk.

She had bright pink hair, wore her Konoha protector like a hairband with bangs to cover her forehead. She had large green eyes and fair skin, and wore a red qipao dress with short sleeves, featuring white circular designs.

Underneath, she wore tight green shorts and standard ninja sandals. At the next desk to her, Sasuke Uchiha was seated, his hands placed on his chin with elbows on the desk, in a deep, brooding posture.

He wore a navy blue, short-sleeved shirt with a high collar, white shorts, and, for a time, white arm warmers. His dark eyes were half-closed as he glanced at the newly entered Kakashi.

Sakura immediately straightened up. "Good M—" she started, but Naruto unintentionally interrupted her.

He shouted in loud voice, "Finally, you're here! Woh-Hoh!"

Smack!

Sakura immediately punched Naruto on the head, then smiled at Kakashi wearily, "Sorry about him, he's just a little idiot."

Sasuke ignored their antics, maintaining his calm posture, thinking he was a cool guy. Kakashi glanced at the three of them.

He smiled under his mask, and for the first time since he had transmigrated last week, he felt a wave of nostalgia. He thought, 'Seeing these three together like back in anime, really brings a nostalgic feeling, hah!'

He then spoke to them, "Alright, take a seat on the front benches."

Sakura looked confused. "Sensei, aren't we going outside like everyone else?" she asked.

Kakashi shook his head. "Today is just an introduction day. There's no need to go outside for such matters."

Sakura nodded, and the three of them sat on the same front desk, with Sasuke on the window side, looking sometimes outside and sometimes at Kakashi, as if analyzing him.

Sakura sat in the middle, sneakily glancing at Sasuke, and Naruto sat on the outer side, grumbling at seeing Sakura looking at Sasuke.

CLAP!

Kakashi chuckled at their actions and grabbed their attention with a loud clap, drawing their focus completely to him. With his hand resting behind on the table, he said, "Well, let's begin with introducing yourselves."
