[Konoha Training Grounds— The Uzumaki Heir]
"So, in order to transform a Rasengan into Rasenshuriken, you need to do three things at once. Create the Rasengan and stabilize it while also adding wind nature chakra to transform it into the Rasenshuriken." Minato said as he listened to Naruto's explanation about how the Rasenshuriken is formed.
The Rasenshuriken's learning method which Naruto had received as a reward from the System could only be seen on a System screen. As such, Naruto was explaining what he had read about the Rasenshuriken to his father since it was Minato's lifelong dream to create an elemental nature Rasengan.
"Yeah! The System has even advised to use Shadow Clones' help in creating the Rasenshuriken as they can handle a single part of the creation, making the whole process far more easier." Naruto replied.
It had been around three weeks since the Battle Royale had ended. Once the dust had settled, it had been found that the Battle Royale broadcasted by the System was visible not only in Konoha but the entire world, thus making everyone aware of the System's might.
As such, Minato had been busy handling the aftermath for weeks and it was only now that he could find enough time to ask about the Rasenshuriken.
"Using Shadow Clones to handle several parts of the Jutsu Creation, that is really a novel approach. Though I believe this will also make the Jutsu far more taxing. Especially since it is already an S-Rank Jutsu."
"That's correct. According to the System's notes, even a Shinobi with Kage level chakra reserves would only be able to cast Rasenshuriken two to three times." Naruto said, confirming Minato's suspicions.
"By the way, have you completed your Senjutsu training, Father?" Naruto asked suddenly.
Senjutsu was an obscure Shinobi art which allowed a Shinobi to absorb chakra right from the nature around him. This technique was very dangerous and very few people knew about it in the entire Elemental Nations.
"Where did you learn about Senjutsu?" Minato asked, confused how Naruto knew about such a high level subject.
"It is written in the System's notes." Naruto answered.
"Well, to answer your question, I can use Senjutsu to access nature chakra but still have not obtained control over it. Training Senjutsu requires me to go into secluded training with Toad Sages for months. I barely manage to find enough time for my family so how can I even go for Senjutsu training? Why did you ask though?" Minato asked.
"Because Rasenshuriken is an unstable Jutsu by nature. Without nature chakra to make the Rasenshuriken dense enough that it can be thrown, it would only be possible to use Rasenshuriken in melee. And that is something absolutely forbidden."
"But why?" Minato asked curiously.
"When Rasenshuriken hit its target and explodes, its explosion creates extremely fine wind blades. These wind blades are so fine that they can pierce through skin and sever those nerves and veins which carry a Shinobi's chakra. Moreover this damage can't be healed with Medical Ninjutsu. If the user is not prepared, he can damage himself while using Rasenshuriken so severely that he may never be able to use Ninjutsu again in his life."
One had to commend the System in this regard though. Not only did it warn the reader in its Jutsu learning method's notes, it even provided a simulation on how the Jutsu was created, thus making it extremely easy for the reader to learn the Jutsu.
Though Naruto knew well enough that he was still to far from actually being capable of practicing the Rasenshuriken. His chakra reserves were not big enough for the Jutsu and he still had to learn the nature transformation.
"Damn! Looks like I would have to finish my Senjutsu training. Though that would only be possible after I can actually learn Rasenshuriken." Minato said, knowing how difficult it would be to actually create the Rasenshuriken even though he already knew how it would be created.
After all, learning Rasengan was not an easy task despite it only having three simple steps. Learning Rasenshuriken would only be harder.
Even Naruto's mother Kushina Uzumaki had taken literal years to learn the Rasengan. His sister Narumi was still stuck on the last part though the main reason for that was her lack of chakra control.
"What about your progress with other rewards? Have you—"
"Reporting to Lord Hokage, the battle between your daughter and Neji Hyuga would start soon. You should depart now to make it in time."
An ANBU suddenly interrupted the father son conversation as he reminded them about the upcoming battle between Narumi and Neji.
As the battle between the two of them could not take place because of the System's intervention, they had decided to have a private battle to end their enmity once and for all.
"Oh, look at the time!" Minato exclaimed in embarrassment as realized that they had almost missed the battle.
Thankfully, they had been reminded in advance. Otherwise, if they had missed this battle, the father and son duo would have faced some real thrashing from the women of the their family. Especially since Minato had not been home much in the last three weeks.
"Shall we?" Minato said, offering his hand to Naruto.
Naruto grasped his father's hand and in the next moment, he was suddenly at Training Ground No. 7, watching Narumi glare at Neji with some really fierce intensity.
No matter how many times Naruto experienced the Flying Thunder God Jutsu, he couldn't help but be amazed by it. He longed for the day he would become capable of inheriting his father's signature Jutsu.
"Naruto!" Satsuki waved at Naruto as she saw him. Right after her, a blue haired girl with the translucent eyes of Byakugan waved at him from the side of a stern man who also had Byakugan.
She was Hinata Hyuga, Narumi's best friend and the one for whom she was fighting Neji. The stern man beside her was her father Hiashi Hyuga, the Hyuga Clan Patriarch. There was a brown haired girl with Byakugan on the other side of him, his second daughter, Hanabi Hyuga.
As the date of the match had been fixed in advance, a lot of people were here to watch it.
Naruto and Narumi's friends from the academy, their teachers and many of their parents too. There were also several Konoha Shinobi here to watch the Hokage's daughter fight.
"Looks like you are quite popular with the ladies." Minato teased Naruto upon seeing Satsuki and Hinata wave at him.
"Oh, come on—"
"We can finally start!"
Naruto couldn't finish his words due to Narumi's interruption as she took her place on the training ground, raring to fight Neji.
"Looks like you can't wait to lose." Neji said in an aloof tone as he also took his place.
Seeing that both of them were ready to fight, Kakashi, Narumi's teacher and Minato's student took his place as the referee.
"Ready, start!"
As soon as Kakashi started the fight, Neji shot towards Narumi while she created several Shadow Clones to engage Neji.
"Useless! These clones can do nothing against me." Neji said as he easily finished several Shadow Clones with his Gentle Fist.
"Then, try this!" Narumi replied as she opened several storage scrolls releasing a huge amount of water while her hands moved through hand seals.
Water Release— Water Tornado
The clones moved out of Narumi's way as a swirling tornado made of water formed and headed straight towards Neji.
However, Neji didn't fear this Jutsu the slightest bit as he bravely rushed forward.
Eight Trigrams— Vacuum Palm Wall
He released Vacuum Palms from both of his hands, destabilizing the water tornado as he headed right inside it.
Eight Trigrams— Rotation
Using Rotation to create a chakra barrier to protect himself, Neji pierced through the water tornado and attached Narumi.
Eight Trigrams— Two Palms
Neji's palms moved elegantly as they swiftly blocked two of Narumi's chakra points. But this was just the start of the signature Eight Trigrams Combo of the Gentle Fist.
Eight Trigrams— Four Palms
His palms moving more swiftly as the combo continued, Neji blocked yet another four chakra points of Narumi. However, this was as far as he could go as Narumi successfully formed a tiger seal with her hand under his assault.
Water Release— Rising Water Slicer
The puddle underneath Narumi's feet rose up to form a huge blade, making Neji disengage or risk being cut by it.
It was at this moment that Naruto noticed something.
'Why is Narumi Kyuubi's chakra? With Kyuubi's chakra, she can unlock her sealed chakra points and also gain more than enough strength to defeat Neji easily.'
'Then why is she not using it?'
