The real Seto and his remaining clones, as they could see the tailed beast collecting chakra within the barrier near it's mouth. Seto previous experiences with Shukaku means he knew his companion or soon to be controlled companion surmises that Seto knew what he was gonna do. The focused determined eyes of the Sharingan followed the movements of Shukaku's eyes with ease, making note of his movements and translating it to the brain of Seto. His reflexes firing on all synapses allowing the Uchiha to react with little to no thought as if he operated on pure impulse and not thought pattern. The opening of the barrier had started as Shukaku clapped his hands together sending a force of chakra upward toward the first ball of flames, as the explosion of flames happened air currents radiated outwards in all directions as the real Seto's hair was blowing violently from the velocity of wind as fire shot down into various places around Seto and the areas surrounding the barrier of burning fire on top of the sand.
The clones standing near Seto got blew back as well as Seto who started sliding back four meters, though maintaining his upright balance as the false clones started hitting the sand and rolling for quite abit before dispersing into poofs of smoke. The real Seto watched as Shukaku launched himself into the air as if he was jumping toward the opening. As the force of Shukaku was coming toward the opening of the barrier the second ball would smack Shukaku again, as the brunt of that fire would blow into the barrier as flames start to burn the sand inside the barrier. The body of water the north Seto and clones came out of the body of water was six meters from the front of the barrier. The real Seto saw the chakra beast and what he was aiming to do with that chakra blast. The real Seto focused his chakra as he looked as if he disappeared from the spot he was standing in as the blast went off. The real Seto had committed the area to memory and knowing that using his shunpo step to go fifteen meters back would put him near another body of water to his right, as he appeared he slide back two meters, the blast ripping open sand and rock and causing the ground to start collapsing inward into the water coming toward Shukaku.
The form of Seto seen Shukaku land as he had landed. Seto knew the blast of chakra would buy him the time he needed to collect chakra within his chest, as Shukaku charged the distance between them was 18 meters as the ground that broke apart from the blast had grown to an ten meter hole going across now with an width of seven meters open of nothing ball water separated the two. Seto would fire the blast toward Shukaku, as an massive sea of flames rushed toward Shukaku flying over the body of water toward him, it's body of mass was massive. Daring to swallow Shukaku into nothingless of burning ash. The remaining three clones behind the barrier that now no longer exist stood and watched on.
After the real Seto fired the blast, the flames doubled in size spreading out into an thirty-five high meter burst of flames toward Shukaku. The expanding burst of flames expanding to forty meter width flying toward Shukaku, as hopefully this would be the end all be all for Shukaku in terms of taking damage. The flames built up with an high enough wall that Seto couldn't be seen by Shukaku by the sheer velocity of flames rushing toward him and outward in a blast of Katon that dared to burn Shukaku and singe the rest of the sand in the area from being used. As Seto stood watching the fire rush toward Shukaku and the momentarily moment of Shukaku not being able to see Seto due to the high velocity and height of the flames, Seto's sensory kept tabs on Shukaku and what he was doing. Meanwhile, the three remaining clones were behind Shukaku were completing hand seals at this time of Tiger → Ox, as they collected chakra swelling up from within there chest and shot the wind from the three. The winds flying in from the south of Shukaku daring to hit him in his back and send wind to make the flames they will end up colliding with to spread among the flames already burning in the area to force them to blow toward the back of Shukaku. The remaining threw clones having used up there last remaining amounts of chakra poof from existence leaving behind a plume of smoke.
The burning of the first and second ball of Naga remaining flames was now burning the sand within an seventy meter diameter around the barrier where it used to be standing. The wind release great breakthrough spread that fire making it burn even more sand as the wind were making the flames of fire spread onto other sand, burning it. Seto's Sharingan taking in the monstrosity they he unleashed upon Shukaku. He was focused and wanted to show Shukaku that his own strength was enough to protect Konoha and his friends and fellow village members. That can stand up to Shukaku without his power he has given him. To prove his worth. And, give Shukaku a chance to learn to believe in Seto. And, to start to accept him so they can bond into one. Friends. Not just an increase to power. Not to hold Shukaku as a prisoner. But, to be his friend.

Those Eyes Can See Through Everything:
When the Sharingan is active, and with his lifetime use of the Sharingan, Seto can commit things to eidetic memory and perfectly recall whatever he is looking at in perfect detail, be it writing, movements, locations, facial features, clothing, anything can be committed to memory that he focuses on.
Note: Everything after seven-eight hours of me and Zack speaking back and forth we we worked out our differences and this is what we agreed upon on discord between ourselves would be the outcome. Shukaku would have no durability after this and neither would Seto. All clones standing next to Seto would have poofed.
