Sasori looked at what looked like a large ball of sun forming in Shota's hand. The rotating sphere of fire grew brighter and hotter with every passing second.
The air around it shimmered violently from the intense heat. Sasori knew he could not let the boy complete this jutsu or it would end very bad for him.
He used the Third Kazekage puppet's kekkei genkai and cast a powerful jutsu. "Black Iron Fist!"
A huge fist made of iron sand formed instantly and shot upward toward the floating Shota. The massive attack carried crushing force and sharp edges. Shota, still pouring chakra into his own technique, simply pointed the growing jutsu in front of him and held it steady like a shield.
When the Black Iron Fist came close, the iron sand literally melted and turned to liquid before it could even touch the fiery sphere. Molten droplets rained down onto the desert sand.
"How is that possible?" Sasori muttered in disbelief.
He now had no doubts that if the jutsu hit him, neither his iron sand defense nor his immortal puppet body would survive.
Everything would be turned to ashes in an instant. The power radiating from that spinning ball of fire was on a completely different level.
Shota thought as he kept pouring all his remaining chakra into the technique, 'I have been doing it all wrong. While fire principles would increase the power of the jutsu, the real strength of the jutsu lies in the basics of Rasengan.'
With Rasengan's rotation and fast speed, the fire constantly moving at a high rate increases the temperature tremendously. 'And then comes Rasengan's principle of power — increased chakra density to burst apart.'
'And finally containment — compressing the chakra into a stable structure.' Shota thought as what literally looked like a huge sun formed in his hand. The sphere glowed with blinding white-gold light. Waves of heat rolled off it in visible ripples, causing the desert air to distort.
Sasori was sure that the jutsu was similar to a tailed beast bomb but instead of just pure large amounts of chakra, this jutsu was formed using fire.
'And he had used some fire principles to make sure fire creates more fire, thus substituting the need of large amounts of chakra. Incredible... Is this his art?' Sasori thought, astonished and for some reason happy that the young boy who used to follow him had finally found a way to express himself.
'But I cannot let that annoying brat just kill me yet. I want to see what more he can show me,' Sasori thought as he unfurled the final scroll which contained a special puppet. It was his most precious and strongest puppet — a creation far stronger than even the puppet of the strongest Kazekage.
Shota threw the jutsu downwards with everything he had left. His clothes had already started melting from the extreme heat of his own technique. Burns covered parts of his arms and shoulders, but he did not stop.
"Cruel Sun," Shota muttered as the large ball fell from the sky.
The desert battlefield transformed completely as the Cruel Sun descended. The massive rotating sphere of fire lit up the entire area like a second sun had appeared in the middle of the day.
Sand for hundreds of meters around began to glow orange and melt into glass. Waves of scorching heat rolled outward, causing the air itself to shimmer and warp.
The sky seemed to burn as the jutsu fell, leaving a trail of superheated plasma behind it. The light was so bright that looking directly at it hurt the eyes.
Sasori's iron sand defenses began melting and evaporating even from a distance. It was an S-rank jutsu at the very top tier — something that could change the landscape permanently if it landed fully.
Shota watched with tired but determined eyes as his strongest technique fell toward Sasori. 'It was good while it lasted, Sasori nii-san. Let us hope you find a way to come back from the dead,' Shota thought.
But his eyes suddenly widened in shock as he saw his jutsu being cut apart into two by a silver flash. The massive ball of fire split cleanly down the middle with almost no resistance. The two halves of the Cruel Sun veered off to the left and right sides, missing Sasori completely. They crashed into the desert dunes far away with tremendous force.
The explosions that followed were catastrophic. The left half of the Cruel Sun slammed into a large dune, instantly vaporizing thousands of tons of sand and creating a massive crater that glowed with molten glass at the bottom. A towering pillar of fire and smoke rose into the sky.
Shockwaves spread outward, shaking the ground violently and sending waves of superheated air rolling across the battlefield. The right half created an equally devastating explosion, forming another enormous crater.
Shota stared in complete disbelief as the silver flash disappeared. His strongest technique, the one he had poured everything into, had been sliced apart like it was nothing.
The destructive power that should have ended the fight was now wasted on empty sand dunes. He felt his strength rapidly leaving his body from chakra exhaustion and the burns covering his skin.
The last thing Shota saw before he started falling from the sky was another puppet standing in front of Sasori. It was a human puppet with white hair and a white cloak, holding a shining blade that still glowed from the chakra that was being poured in it.
'Is that Sakumo Hatake, the White Fang... how?' This was his last thought as he succumbed to unconsciousness midair. His body went limp and began dropping toward the scorching desert floor below.
