The Fourth Generation Kazekage Rasa, Gaara's biological father, was also the culprit who sealed Shukaku within Gaara's body.
To make it easier for Gaara to control Shukaku, Rasa deliberately weakened the sealing power, which directly led to the One-Tail Jinchuriki easily going berserk.
But now, Yuta was very grateful for the shoddy seal Rasa had made; perhaps even Rasa hadn't expected that the seal he personally created would undergo some subtle changes, changes that directly suppressed Shukaku's true power.
"Damn ants!"
Shukaku roared angrily at the sky; as one of the Nine-Tailed Beasts, being beaten by a Summoning Beast like Gamahiro greatly stimulated Shukaku's already fragile nerves.
"Wind Release: Infinite Sand Cloud Great Breakthrough!"
"Whoosh! Whoosh! Whoosh!"
A massive sandstorm tornado swept up, and Gamahiro nervously gazed around: "Yuta, I can't see the surroundings."
"The large amount of Chakra contained in this sandstorm is preventing detection; we must escape from here first," Yuta said through gritted teeth.
Gamahiro's main strength lay in his two long swords and two toad fists; facing such a wide-range Ninjutsu, Gamahiro had no good way to deal with it.
"Whoosh!"
A piercing sound of rushing air rang out, and a wind bullet containing a massive amount of Chakra tore through the sandstorm.
Gamahiro looked at the rapidly enlarging wind mass and quickly held his long swords in front of his chest; at this distance, it was too late to dodge.
"Boom!"
The Drill Air Bullet, containing violent power, directly sent Gamahiro flying.
"Desertification!"
The land within a thousand meters centered on Shukaku rapidly turned to sand, and Shukaku raised its right hand, shouting excitedly: "Die!"
"Boom boom boom!"
Under the influence of Shukaku's Chakra, a hundred-meter sand sea rose from the ground and surged towards Gamahiro.
"This is bad," Yuta quickly formed hand seals with both hands.
This place had become Shukaku's advantageous combat environment; at this moment, Gamahiro alone could no longer cope.
"Water Release: Great Waterfall Technique."
Yuta once again spewed a large amount of clear water from his mouth, striking the sand wave, and Gamahiro took the opportunity to flee backward.
"Boom boom boom..."
"Shukaku's power is growing," Yuta looked at Shukaku helplessly.
"Boom boom boom..."
The sand sea gradually calmed down, but strangely, Shukaku did not pursue the disheveled duo.
"What is Shukaku thinking?" Yuta stared at Shukaku standing in the sand sea; a quiet Shukaku was more unsettling than a berserk Shukaku.
"Tap tap tap..."
"Hm?" Yuta looked down at the small, slightly vibrating stones on the ground.
"Click clack click clack click clack..."
"Gamahiro, jump!" Yuta suddenly shouted loudly.
"Boom!"
The moment Gamahiro jumped, the ground rapidly collapsed, and Yuta looked at the land that had become a sand sea, feeling lucky: "That was close."
"Myriad Sand Spikes!"
Shukaku slammed its two hands on the ground, and hundreds of sand spikes, each over ten meters long, shot like a rainstorm towards Gamahiro, who had nowhere to gain purchase.
"Whoosh whoosh whoosh..."
Yuta jumped down from Gamahiro's head, extended a chain, and firmly bound the katana: "Gamahiro, throw me over."
"Be careful," Gamahiro threw the long sword with force.
Yuta formed a hand seal with one hand: "Summoning Technique: Release!"
"Bang!"
"Damn brat!" Shukaku opened its large mouth at the long sword: "Drill Air Bullet!"
Looking at the rapidly enlarging Chakra wind mass, Yuta crouched slightly and jumped with force.
"Boom!"
The katana was knocked away by the Drill Air Bullet, and Yuta, in mid-air, extended another chain from his back, nailing it into Shukaku's head.
"Thud."
Successfully landing on Shukaku's head, Yuta quickly dodged the sand bullets that shot out from Shukaku's head.
"Stop it right now, you damn brat! I don't want to go back to that dark place!" Shukaku frantically swept its head with its hands, but these clumsy attacks couldn't hit the agile Yuta at all.
"Get off me!" In a fit of desperation, Shukaku summoned a sand sea to attack its own head, while Gaara was reabsorbed into Shukaku's body.
"Damn it," Yuta looked at the sand sea and gritted his teeth fiercely, not expecting this damned Shukaku to be so ruthless.
Before the sand sea could arrive, Yuta's consciousness sank into his mental space and he said to Kurama: "I agree, five is five."
"..." Kurama lay on the ground, silently looking at Yuta.
"What do you mean?" A bad premonition flashed through Yuta's mind.
"..." Kurama continued to look at Yuta.
"Alright, ten," Yuta's eyelids twitched slightly twice.
"..." Kurama still didn't speak.
"Don't go too far," Yuta was a little annoyed.
Hearing Yuta's words, Kurama finally spoke: "The sand sea is coming."
"..." Yuta took a deep breath and stomped his foot angrily: "Twenty! Is that okay?! If not, then forget it!"
"Deal, don't go back on your word," Kurama sat up; Kurama still understood the principle of quitting while he was ahead: "Is it that one-tailed thing outside? Leave it to me, don't worry."
Looking at Kurama's smug expression, Yuta gnashed his teeth in hatred; this unlucky fox was getting more and more skilled at extorting, exiting the mental space, Yuta stomped twice on Shukaku's head with a gloomy expression.
It's all because of you!
"Gurgle gurgle... gurgle gurgle..."
The Nine-Tails Chakra enveloping Yuta underwent a subtle change; a fourth tail extended once again, and the illusory Chakra solidified, as Yin-Yang Chakra converged proportionally in front of Yuta's mouth as he raised his head.
"Boom boom boom!"
Because a lot of time had been wasted in the mental world, the sand sea was already approaching overhead.
"Too slow, you trash with only one tail."
Kurama grinned and fired an incomplete Tailed Beast Ball; this was the limit that could be achieved in the Four-Tails state.
"Whoosh!"
A fiery red light streaked across the sky, and the next second, the world lost its color!
"Boom!"
The incomplete Tailed Beast Ball exploded a thousand meters in the air; even from such a high distance, the violent Chakra turbulence still affected the ground, uprooting trees, evaporating lakes, and cracking the earth.
"Whoosh."
Kurama was not in the mood to admire the power of the incomplete Tailed Beast Ball; its right hand pierced into Shukaku's head, and hundreds of Chakra arms branched out, quickly searching for Gaara's location.
"Found him!"
Kurama raised its hand and grabbed Gaara, and just as Kurama was about to kill Gaara, Yuta suddenly said in the mental space: "Don't kill him."
"Tch, troublesome," Nine-Tailed pouted, and with a backhand, threw Gaara to the ground.
"Crack... crack... crack crack crack..."
Without Gaara's support, Shukaku's eyes lost their luster, and large cracks appeared on its body, like parched land exposed to intense sunlight.
"It's dealt with, don't forget my cake," Nine-Tailed instructed before returning to the mental space.
"Whoosh whoosh whoosh."
Yuta deactivated Nine-Tailed Mode and landed on the ground with the sand flow.
"Thud."
Yuta pretended to be exhausted and fell to the ground; for realism, Yuta even used Water Release to condense a few drops of water on his forehead.
"Hoo... hah... hoo... hah..."
For a moment, only Yuta's heavy breathing remained on the battlefield.
"You..." Gaara, severely injured and unable to move, suddenly asked: "Why can you go to such lengths for the people in this Village? The pain and malice you've endured should be the same as mine, so why protect such a Village?"
"I'm not protecting this Village at all," Yuta laughed wryly: "The people in this Village have given me no other feelings besides malice; probably ninety-nine percent of them wish I would suddenly die one day."
"Then you still..." Gaara asked, puzzled.
Yuta chuckled softly: "Because I've decided to protect a certain idiot, and this Village has people he values; he definitely wouldn't want this Village to be destroyed."
"..." Gaara silently looked at Yuta; he didn't understand Yuta's words or the emotions contained within them.
"Hey, don't you have anything you want to protect, kid?" Yuta struggled to get up and looked at Gaara.
"No," Gaara closed his eyes.
"Nothing at all?"
"No."
"Then, does no one care about you? Even just a little?" Yuta looked at the two cautious figures not far away and asked again.
"No..." Gaara was about to say this, but for some reason, two persistent figures appeared before his eyes.
"Gaara!"
Warm arms helped Gaara up, and Gaara opened his eyes in surprise.
"Gaara, are you... are you alright?" Temari asked nervously.
"..." Gaara lowered his head and didn't answer.
"Yuta!"
On the other side, Naruto and Sasuke also rushed over, blocking in front of Yuta, warily watching Kankuro and the others.
"What is it?" Yuta said with a smile: "Someone does care about you, after all."
Gaara looked up at Kankuro and Temari; the concern hidden beneath their nervousness and fear caused a subtle stir in Gaara's heart.
"Yuta has lost his fighting ability, and I can't fully exert my strength due to the Cursed Seal, so we should try to avoid combat," Sasuke quickly analyzed in his mind and decided to retreat, gesturing to Naruto with his right hand behind his back.
"Whoosh."
Naruto, supporting Yuta, quickly ran into the forest; Sasuke, holding a Kunai, slowly retreated step by step, turning to leave once he reached a safe enough distance.
"With this, Gaara's problem is solved; I hope he can successfully become the Fifth Generation Kazekage like in the original world. At least my efforts should yield some return," Yuta unconsciously smiled smugly.
The reason Yuta acted completely differently from his usual self was very simple; it wasn't some so-called empathy between Jinchuriki. In the original timeline, Gaara later became the Fifth Generation Kazekage of the Hidden Sand Village, and befriending a Kage of a Ninja Village was Yuta's ultimate goal.
I know this chapter is a bit toxic, please don't hit me. I'm not very good at writing the part about persuading others, but Gaara will play an important role for Yuta in the future, so...
