It was half an hour later that Itachi and Shin burst out of the summoned dog, as it vanished in a puff of smoke.
But the first thing that came to their eyes wasn't a battlefield filled with tension, but one filled with war.
" Ora! "
A loud yell given by Kasamaro was heard clearly through the massive noise of the battlefield.
* Bang *
Itachi's head turned quickly all around as he guessed the situation with the surroundings, filtering out the noise.
' They were provoked, neither Mist nor Akatsuki would want to fight this intensely without some solid gain, was it Uchiha madara? '
Itachi's mind quickly calculated the most probable scenario amongst the countless possible ones.
So now there was only one thing left to do.
* Bam *
Kicking Shin away hard enough that his body collided with a ruined buliding nearby, Itachi's flaming red susanoo erupted on the battlefield.
Successfully taking the attention of everyone present, he wouldn't mind Akatsuki losing out, but Mist was currently his brother's ally, he didn't want to cause his brother any troubles.
Can you imagine what would happen if say a jinchuriki dies to help Konoha's Uchiha clan leader? Itachi didn't want to imagine it, as he was about to not let that happen in the first place.
" Amaterasu "
Everyone immediately dodged the wall of flames that erupted at their feet, some blocked it with their swords, some used ice mirrors to flash away and some blurred out of the way.
" What the hell?! It burns! "
Screamed Hidan as his hands were trembling, burning with the black flames he accidentally touched from his scythe.
Itachi's emotionless eyes looked at everyone present, successfully attracting attention and hatred, he made sure the war stopped and his brother won't be blamed for it.
" If you want to live, cut off your hand. "
Itachi spoke without care to Hidan, who looked royally pissed but immediately slashed his arms.
Looking at his fallen arms burned to ash within a few seconds, he gave Itachi a murder filled look.
If only looks could kill, wait they do, but sadly it was Itachi's looks that did that, not Hidan's.
" This is our fight, stay out of this, unless you want to die first. "
The Akatsuki didn't communicate and immediately stepped back, they wouldn't want to fight Itachi without a good enough reason.
And Mist looked at Kasamaro for confirmation, who stood in his place for a while, before nodding and backing away.
Mist too backed away seeing that, and Zabuza broke apart his own kubokiribocho after watching Hidan's hand, he was the one who had blocked Amaterasu with his sword.
' It needs blood. '
Thought Zabuza as he looked at the sword, now all but a handle, it's blade burning away at his feet, Amaterasu flames consuming it.
But Zabuza didn't care, this was a legendary sword, kubokiribocho, all it needed was a little bit of blood, and it would regenerate immediately.
* Bang *
A rock fell from the place Shin had been kicked at, and the building remains immediately burst open.
" Susanoo "
With a war cry emitted from Shin's throat, a purple half humanoid body took shape, Shin's susanoo was in it's third form.
" That hurt brother. "
Said Shin as he smirked, not looking hurt in the slightest, his susanoo was purple, it's left hand held a crossbow, with round shield like design.
And his right hand held an orb, from which an arrow protruded like a sword.
Yes, Shin's susanoo was the exact same as Sasuke's susanoo, surprise surprise.
" If that much hurt you, you might as well give up, little brother. "
Said Itachi, again without emotion, he and Shin had made a deal, now the only thing remaining was fighting a mock battle.
This farce will have to end after that.
" Hurtful! "
* Siwsh *
* Bang *
Blocking a blinding fast arrow released from the purple susanoo, Itachi looked calm.
Itachi understood looking at Shin's Susanoo, that it was a long range one, and his was an all rounder, none of the arrows would hurt him with the yata mirror in place.
It was quite literally the perfect defence, his shield, yata mirror changed it's nature to whatever nature of attack hit it, theoretically, it can block even a truth seeking orb.
As those too, were composed of all nature releases combined, something the yata mirror can change into autonomously as soon as it encounters it.
" Yasaka magatama. "
Said Itachi as his susanoo raised it's arms, it meanwhile kept turning and it's shield kept blocking the blindingly fast arrows released by Shin, who was running circles around Itachi to get him to make a mistake.
One mistake and the arrow would penetrate straight through Itachi's susanoo armour, because it too, was made of the same material.
Itachi's only defence was the yata mirror, so Itachi did what any smart person would in this situation, attack back.
" The yasaka magatama! "
Exclaimed Shin as he saw Itachi's susanoo raise his hand and the sword of totsuka vanished, in it's place three spinning tomoe took shape on the Susanoo's palm.
* Wisssh *
And they came for Shin's Susanoo with immense speed, Shin's susanoo could handle it, but it would crack, so Shin used his own strengths to counter it.
* Tiiinnnnng *
The three spinning tomoe connected with Shin's Susanoo, as it raised it's left arm up, the one with a crossbow.
His crossbow had a round shield built into it as well, it was no yata mirror, but it was a thick susanoo shield.
Built with shock absorbers, as it was part of a crossbow design.
So all three beads collided with the shield, causing sparks of chakra, as the spinning tomoe attempted to cut through the thick shield.
" Hup "
Understanding their rotation would chip away at his shield's durability sooner or later, Shin's Susanoo turned on it's axis and the shield pushed the yasaka magatama beads away.
* Boooom *
And it collided with the ground, causing a massive crater to emerge and a whole lot of smoke to be emitted.
Shin turned his head back towards Itachi as he just saw the destruction.
" That was some narly stuff- Hey! What the hell man?! Another one! "
Before Shin could release a sigh and trash talk, Itachi's susanoo had grown extra arms and now all three empty arms called for yasaka magatama, his last arm still held onto the yata mirror.
Giving Shin zero possibility to attack him with his crossbow.
Shin's forehead popped with blood vessels showing, he was pissed.
" Not only you can grow extra arms, behold, yasaka magatama! "
Shin's susanoo grew out extra two arms as well, Sasuke's Susanoo by default had three when not mastered, Shin only removed the limiter and grew out all the available ones.
It wasn't only Madara who could do stuff like this, Sasuke's susanoo was no joke, but it's user in the series left a lot to he desired.
As soon as the arms grew, they too created two yasaka magatama attacks, and his original arms got into position to fire his arrows.
' Good job Shin. '
Said Itachi proudly in his mind, as he understood exactly what Shin was going for here.
Shin had made use of the training ground jutsu well enough, this much Itachi can tell.
Meanwhile the audience was sweating, the sheer skill they were showing was immense, every attack was fast enough that even one slow reaction would mean death, and both brothers were attacking and dodging as if this speed was nothing to them.
Utakata was now slowly realising, why Mizukage sama wanted to help Shinnosuke Uchiha, even without the benifits, a possible ally this strong was worthy enough as an investment.
