9 Eight Inner gates

Ever since being adopted into the Uchiha family, Satoru had only one thought in his mind, 'The Uchiha Massacre'.

To stop it or at least minimize its effects Satoru needed strength, strength to defeat an entire army of shinobi.

So, the question now was how could Satoru get this power so soon, he couldn't just go to google and search, 'How to get Op real fast tutorial by Uchiha Madara.' or 'How to stop an entire revolution being led by madmen using Talk no Jutsu.'.

So the only option left was to rely on himself. Then he came up with a plan that would let him minimize the effects of the Uchiha massacre, while not putting the Village and the Uchiha clan in danger.

The plan was to use his Cursed Technique Equivalent Exchange and then get Rikugan and transforming himself into a Cursed spirit or a half Cursed spirit like Itadori Yuji and Choso.

These two things will help him greatly. But to do this Satoru needed a large amount of Cursed Energy because apparently, these two things were expensive as hell.

So now he had two options either get enough Cursed Energy which was not possible or store enough for the Exchange.

The answer was obviously the latter option.

He then reduced his Cursed Energy by 95% which would work as a generator for his Cursed energy battery, leaving him with only 5% to work with, but just in case he gets into a hairy situation he made a little system by which he could go full power at any time without using his stored up Cursed Energy.

And the password to unlock the seal on his Cursed Energy was 'OPEN'.

'What just happened, the boy's power and speed just went up explosively..., OPEN when he said it something changed, most likely some kind of limiter,'

'A physical limiter like 8 gates, most likely, and since he is going all out I need to respect it and give my best as well,' Gai thought as he pulled out two nunchucks and did a weird pose.

Satoru who was now in the state of Zone and had full control over his Cursed energy, charged toward Gai at incredible speed and punched.

'Fast,' Gai swung his nunchucks to block Satoru's attack, Satoru fell back then again charged towards Gai, he punched and Gai swung his nunchucks.

Suddenly, Satoru performed a knee release and ducked down, he then grabbed some small rocks scattered on the ground and threw them towards Gai.

Gai used his other free nunchucks to sweep the debris away. This was what Satoru wanted, Gai now had no free nunchucks to defend himself and so he punched towards Gai's chest.

But one thing he didn't take into account was Gai's legs were still free. Gai kicked Satoru as Satoru defended with his free arm.

But then suddenly, Gai felt a sudden pain in his chest where Satoru was aiming.

'Divergent Fist'

Gai was hit by an after impact of divergent fist which Satoru launched. Within the six years Satoru had been here, he didn't do much except for training and mischief along with other daily activities.

One day while fighting a Chunin he found out that divergent fist is really good for taking opponents by surprise and also made up for his reach disadvantage.

So, he practiced it like a madman and mastered it, even making other new moves to add to this technique. This was when he still only had 5% of his Cursed Energy but now that he had all of his Cursed Energy and was in a Zone, divergent fist was more powerful than ever.

'So this is the strange hit the reports talked about, an invisible attack that comes out of nowhere, it's almost like the range of his attack increased,' Gai dusted off his jacket and took a stance again.

Satoru landed gracefully after being kicked away by Gai and also took a stance, he had a smile on his face along with some blood dripping from his mouth.

He again charged toward Gai and attempted to punch, Gai in response swung both his nunchucks in a cross pattern.

Satoru's fists which were closed for a punch opened and caught both the nunchucks, he then imbued a lot of his Cursed Energy into the nunchucks and pulled them.

Here is a note for all those sorcerers out there, if you put too much Cursed Energy into a vessel like a sword or in this case Gai's nunchucks, the vessel will not be able to handle it and break.

Gai's nunchucks broke only leaving one side of both the nunchucks. He backed out with a few flips and landed a safe distance from Satoru, he then tied the rope of both the nunchucks together to make them one.

Satoru dug his hands into the ground and pulled out a Katana. He slowly imbued some Cursed Energy into it and both charged at each other again.

Satoru swung his Katana and Gai swung his nunchucks. Both were in a battle of who would gain the upper hand and land the first blow or break the other's weapon first.

Satoru's sword forms were an imitation of the Sun breathing's sword forms. He was doing the sword forms without the breathing technique, so, he had no fire running along with his sword.

Satoru performed the thirteenth form but it was still not enough to bring Gai into a corner.

They were both stuck in a tie, until, Satoru formed a plan. He put a lot of Cursed Energy into his blade at once and swung it at Gai who blocked it with his nunchucks.

Satoru's blade broke into pieces and Gai's nunchucks were cut into half and thrown away. The pieces of Satoru katana created a blind spot and he punched Gai with all he had, the punch had some black sparks in them.

'Blackflash'

The punch hit Gai right in the face, he was disoriented, his brain was shaken up. Satoru tried to go in for another but was met with Gai's feet.

'Konoha Hurricane'

Gai's attack had also become faster and hit Satoru. Satoru landed not so far away and then he heard it, Gai screaming the name of his move.

"Eight Inner Gates: Gate of Opening, Open"

Gai had finally pulled out his final trump card, the Eight Inner Gates technique.
