Naruto: Chakra System

A few days passed, and today was finally the day for the mission to the Land of Waves.

Just yesterday, Kakashi had spoken about this to Hiruzen and also found that Tazuna had finally issued this mission yesterday, and started convincing Hiruzen that Team 7 would take it.

Hiruzen was reluctant at first, but with Kakashi's explanation of how much they had improved, plus his own protection to Naruto and Sasuke if anything happens, Hiruzen agreed easily.

"Shall I have a few days rest from training until I'm on this mission?" Kakashi mused, while looking at his system status. Though most of his training was only done by his Shadow Clones aside from little physical training, but even Shadow Clones has limted span time and would be vanish after few hours.

Currently, he was sitting in his room, after getting ready for meeting his students, summoning his system panel before moving.

[Host: Kakashi Hatake]

[Chakra Pool: 634,550/636,000]

[Chakra Control: 91/100]

[Chakra Level: Kage]

[Chakra Affinity: All]

[Chakra Growth: +20,000 per day]

Kakashi nodded. "Well, my chakra reserves are quite good, probably and obviously second after Naruto in Konoha and even my inventory is completed."

His chakra control also increased by 1 more point, all thanks to the Fūinjutsu training he had done. The Dimension-type storage seal he had been working on, well, his Shadow Clones, was ready yesterday and he placed that seal formula on his left palm.

He initially thought to name it as Dimension-type storage seal or Four-Symbol Storage Seal, but they sounded lengthy, so he only decided to call it simply, 'Inventory Seal', since that would be its main function.

However, this was not just a simple storage or inventory that could only store non-living objects; rather, it could, just like a normal Four-Symbol Seal, also store living ninja as well, also Bijuu can be stored and later sealed.

But unlike Four-Symbol Seal or any other seal that used to seal a Bijuu, they were directly connected to a Jinchūriki's mind space, creating a new space for Bijuu and Host to interact, which wasn't part of Kakashi's Inventory seal.

His inventory was just like Kamui dimension, a different space or dimension, which had the main function of storing whatever Kakashi liked, but if a living person or Tailed-Beast came in, they could easily go out, unless Kakashi sealed them intentionally, and this space wasn't as powerful as Kamui dimension.

Though that didn't matter, since Kakashi only made it for weapons and tools storage, and money as well.

After analyzing his current status, Kakashi got up to move, shut the door behind him, and Flickered to the training ground.

Upon arriving at the training ground, Sakura and Naruto greeted him, while Sasuke just gave him a small nod.

Naruto then said, "Kakashi-sensei, I have mastered the 'Wind Style: Gale Palm Jutsu' now teach me that A-rank Ninjutsu that you promised."

Sasuke also gazed at Kakashi expectedly; he had also mastered Lightning Hound Jutsu, and now wanted to learn ahead.

Sakura wasn't much aware that Kakashi promised them about teaching A-rank Ninjutsu, though even if she knew, she didn't have anything to say.

After weeks of theoretical understanding of Medical Ninjutsu, she had finally started to practice in practical, so she wouldn't bother Kakashi about this anyway, and be busy learning Medical Ninjutsu, plus she herself hadn't completely learned Wild Water Wave Jutsu.

Kakashi glanced at them and asked, "Just yesterday, I requested Hokage-sama to give you three your first C-rank mission. Now tell me what you want first, to learn an A-rank Ninjutsu or do your first C-rank mission?"

Naruto's eyes sparkled and he said, "Really? A real mission, Yes, Finally!"

Sasuke also said, "T-then I think a mission is better, we can learn Jutsu later anyways."

Sakura had no say in it; she was okay either way. If not for the mission, she would be practicing medical ninjutsu most of the day, but she also liked to do real mission.

Kakashi nodded. "Alright, that's good," he said. "Now go and pack up your tools and necessary stuff, you have an hour, then meet me at the Hokage Building, in the mission counter, okay!"

"Yes, Kakashi-sensei!" With that, they all Flickered, and in exactly one hour, all three of them came to the Hokage's building, where Kakashi waited for them, and then they moved towards the mission counter inside the Hokage's building.

Inside the mission counter, a brown wooden room with two open windows, sat three figures on chair behind a large wooden table.

At the center sat Hiruzen, on his left sat Iruka Umino, in his Chunin attire, and on his right sat an old man, retired from his ninja duties, now only working at the Mission counter.

Naruto, upon seeing Iruka, smiled, really happy to see Iruka in a few weeks. "Good morning, Iruka-sensei!" he said.

Iruka smiled back. "Morning Naruto; Sakura and Sasuke you too, how are you all doing?" he said.

Sakura replied, with a small bow, "Hello Iruka-sensei, we have been good, Kakashi-sensei really has been taking good care of us."

"Oh, Really, that's good then," Iruka said, then looked back at Kakashi behind them, and greeted him.

Then they all greeted Hiruzen, who was taking a puff of his smoke, and sorting out a few documents. He smiled at them and passed a document of their mission to them.

He said, "I actually don't want to send any newly graduated Genin team to C-rank missions that early, however Kakashi told me you all are ready, so here, this will be your first C-rank mission, an escort mission."

Naruto proudly said, "Yeah, we really have improved, just a few days back, I defeated Kiba easily."

While Naruto started to summarize all his spar details to Hiruzen and Iruka; Sakura and Sasuke read the mission details. Just then, the door slammed open and an old man, with grey hairs, glasses, a large beard and dark eyes, entered the mission counter room, with a bottle of sake in his hand.

He glanced around and at Team 7 and complained, "Haah, what's this? They are a bunch of stupid brats, especially the shortest one, with a super stupid-looking face, are you really a ninja?"

-------------

Well thanks for all the proof you have shown me that Kakashi can't turn his Mangekyō back to Three-Tomoe stage, especially with pictures. But I once again checked in internet on Google and it's still freaking saying NO!

While I remember that seen, when Kakashi and Obito upon Rin's death able to transform their respective Sharingan into Mangekyō, which was also an obvious case that Kakashi's Sharingan is also a Mangekyō just he himself didn't knows about it for long.

But those from Pain's attack arc, and against Kakuzu and Hiden, where Kakashi has Three-Tomoe despite using Kamui before against Deidara, I really didn't recalls them, they were really the small details I missed, at first I only checked it on internet, then at reddit.

And at both I find answer no, with on internet it say that Kakashi's ain't Uchiha and on Reddit one explained it saying that Kakashi's Mangekyō from the time it awakened was de-evole because he hasn't enough Chakra and can't turn it back once finally used Kamui.

But looks like they were all wrong informations, so I will in future keep it correct, consider my mistakes regarding it in story as not happen, and I don't want to correct in back because I would remember I make an error, and once again Thanks For Reading!
