Weak point
*Roar!*
A two meter tall fiery monster was rushing towards another monster, this second monster was made of black ropes and had a fire style mask on it's face.
*Whoosh*
The two tailed monster was Sato and Hinata transformed into a smaller Matatabi.
When the battlefield became deadly Sato suddenly remembered, Naruto had used a combination transformation justu with his toad summon in the orginal story, and transformed the toad into Kurama.
That was the complete Kurama, full with a set of claws and fangs, and this justu was cast using nine tailed fox's chakra too, which is what made it realistic.
*Step*
Sato kept circling around the fire masked monster, he was thankful for Matatabi's chakra right now, without it he wouldn't be able to copy her body so well either.
And he was also thankful for the Inuzuka's as well.
Inuzuka's as a clan specialised in transformation justu and combination transformation justu, if Sato didn't fight the Inuzuka on his way back, there is a high chance he would never think of this.
But now that he had figured out how to trigger the justu with Hinata, he had a big power boost in the form of a Byakugan.
'I am able to use the Byakugan as a transformed creature, Hinata's chakra pathway system is linked with mine, making it possible for me to see through her eyes.'
Linking chakra pathway using transformation jutsu wasn't difficult, Sato did it when he used the justu with both their hands.
Casting justus using someone else's hand was a skill shown in the orginal story, both Anko and Sasuke had it.
It's a very easy skill as long as the partner wasn't resisting, and Hinata didn't resist at all, this is what made it possible for Sato to join their chakra networks.
And with the Byakugan's x ray vision on his side now, the fight became extremely easy for Sato.
"You know Kakuzu, those masks are pretty weird looking, but I can see something very interesting inside them using Byakugan."
*Grin*
"Sister! C! There are hearts beating inside each mask! All of them are connected back to Kakuzu's body."
"Hit those monsters on their chin, there is a weak spot there!"
Kakuzu froze, he was inside Yugito's body right now and was trying to tear it apart, but Sato's sudden exclamation froze him on the spot.
"Shit! How did I forget about the Byakugan!"
Kakuzu cursed and ran out from Yugito's torn belly as fast as possible.
*Bang*
"Aggggh!"
But the only thing which greeted him was Matatabi's smiling face and a broken mask monster, which was just broken by Matatabi's paw.
"Huff huff huff.. you bastard, you almost tore me in half."
*Sizzle*
Matatabi's body started regenerating at a fast rate, as long as tailed beasts weren't killed quickly, they can keep regenerating again and again.
"Attack the chin right? Got it, thanks Sato!"
Yugito and C thanked Sato and quickly attacked Kakuzu.
Now that his weakness was obvious to them, the fight became much easier compared to before.
Kakuzu on the other hand was under great pressure, he had to forcibly call back the fire mask chasing Sato.
"Are you are running away? Good, run as fast as you can."
Sato murmured, until now he was using his agile body to dodge all attacks, but he never once hit back.
He silently looked at the mask monster run towards Yugito, yet he no longer had the desire to chase it.
There was a reason for his actions, his transformation was done with Hinata, and she was barely able to maintain herself.
This transformation might look strong, but because of Hinata's involvement in it, it could take only one hit before collapsing.
And Sato wasn't about to risk it, this is why he kept dodging and kept leaking news using Byakugan, Hinata was so weak he couldn't do anything else at all!
'But now it's over, I need to stay away from the battlefield, Yugito will take care of it all, she is back in full health and has our support.'
'As long as C and I keep helping her from the side, she is bound to win.'
Byakugan was the best support in the battlefield, and Sato was going to support her the best he could using it.
Yugito wasn't weak, her previous loss against Kakuzu was because she didn't know his secret, but now she did know it, so she would not lose.
"Sister, the wind mask is doing something, stop it."
*Bang*
Matatabi quickly attacked the wind mask and Kakuzu stumbled back, he glared at Sato but immediately had to focus on Yugito again.
He hated the Byakugan, he was just about to sneak attack using the wind mask but the Byakugan saw through his plan.
'That bastard Sato is really good at using the Byakugan, if it was just that girl and that Hyuga Neji, I wouldn't be in trouble.'
'All he is doing is sharing his Vision with the girl named Hinata, he dosen't even have full control over her Byakugan, but he is still so good at it.'
'He really reminds me of you, Tobirama.'
Kakuzu kept attacking and defending against C and Matatabi.
Two of his Masks have been destroyed, he was using combination ninjutsu with the remaining three.
This was letting him keep up against his enemies.
'But it's only a matter of time before someone slips up, and with me here, only Kakuzu will slip up.'
Sato maintained a high concentration vision and kept telling Yugito and C what he saw.
But Hinata's Byakugan was starting to hurt, so he had to use it less and less, thankfully the fight was almost over now.
*Riip*
And with a sudden claw, Yugito tore apart Kakuzu's neck.
*Thump*
Killing him on the spot.
Just like that, Kakuzu who had survived since the founding of ninja villages, was dead.
No fancy speech before death, no laughter, not even a final attack, just a quick sudden death.
This was reality not everything could be planned for, Kakuzu never would have guessed that today was his last day.
"It's over.."
*Puff*
The small two tails collapsed into a bunch of smoke and two kids walked out from within.
Sato and a tired Hinata who was hanging on his shoulder, these two were the heroes of today's battle.
And their relationship had gotten significantly closer after this one battle.
