As soon as Satoru released the Yin Seal, all his wounds vanished instantly, and his mental state reached peak condition.
"Flash Release: Mightiest Flash Star Core Wave!" Seeing the Eight-Tails-formed Blue Bee preparing a Tailed Beast Ball, Satoru unleashed all accumulated chakra via Yin Seal release.
The chakra once gained from Sarutobi Sasuke was now fully concentrated in his hands.
This Satoru technique resembled Kamehameha, differing only in using "ki" versus chakra.
The Tailed Beast Ball comprised Yin and Yang chakra, while Satoru's Flash Release chakra fused Wind and Lightning Release. Which was stronger remained uncertain.
Moreover, neither side interfered this time, giving ample prep time for their ultimate attacks.
Finally, the Eight-Tails Blue Bee and Satoru exchanged a silent glance of understanding. In the next second, both unleashed their mightiest techniques.
Satoru fired his Flash Star Core Wave, while the Eight-Tails Blue Bee launched the long-prepared Tailed Beast Ball.
The attacks finally collided.
*BOOM!*
A deafening explosion rang out first, then surrounding trees and ground bore the full brunt.
A massive crater formed instantly.
Everything around Satoru and the Eight-Tails Blue Bee, within collision radius, was utterly annihilated.
Satoru breathed heavily, his body cloaked in white Susanoo.
At the last moment, Satoru used both Mangekyo Sharingans' power. Susanoo and Sage's Cloak protected him from severe damage.
As for the Eight-Tails Blue Bee, he lay on the ground.
"Eight-Tails... defeated?.. That easy?" Satoru approached the fallen Blue Bee step by step, doubts gnawing at him.
"Kill him? Or not?" Killing him would alter history. Worst, his dream of peace in the shinobi world might collapse.
"If I want a voice in the ninja world, I definitely can't kill this guy. After all, he's the cousin of the Fourth Raikage A..." Satoru decided against killing Bee. But as he turned away, terrifying chakra erupted from the jinchuriki again.
Satoru rolled forward, teleporting dozens of meters instantly. Glancing back, he saw a massive octopus tentacle emerging from Blue Bee's body.
Soon, Blue Bee's body fully transformed into the Eight-Tails.
"This... full Tailed Beast transformation?"
"This guy... really berserk now?" Previously, Satoru fought partial transformation Blue Bee, but now faced the fully enraged Eight-Tails.
"GRRRAAAARRR!" The Eight-Tails didn't speak, only roared. It seemed in great pain. Spotting Satoru, it grew even more feral and uncontrollable, charging immediately.
"Looks like I'll have to clash head-on with the Eight-Tails!" Using Body Flicker Technique, Satoru dodged a powerful tentacle strike and grabbed one.
"Ha!" Satoru unleashed Monstrous Strength, spun the Eight-Tails, and slammed it into the ground.
"GRRRAAAARRR!" The Eight-Tails roared, all eight tails crashing down on Satoru.
"Amaterasu!" Blood streamed from one of Satoru's eyes, and black flames ignited on the Eight-Tails' body.
The tentacle meant to crush Satoru was severed instantly, like a lizard shedding its tail.
"Sacrificed part of its body. Wise choice," Satoru thought, then used Enton: Kagutsuchi to cloak his Susanoo's back staff in Amaterasu flames.
In Susanoo state, Satoru swung the Amaterasu-enveloped staff. Each hit elicited agonized howls from the Eight-Tails. This time, Satoru went all-out, using every trump card. After all, his foe was the Eight-Tails! Even among Tailed Beasts, it was immensely powerful.
Satoru's battle naturally drew Hidden Cloud ninjas' attention, but none dared ambush him now.
He single-handedly held back the Eight-Tails.
"This... monstrous! A Konoha kid suppressing a Tailed Beast?!"
"He's just a brat! Unbelievable!"
"When will Lord Raikage arrive?!"
"Lord Bee's berserk! If this continues, he might die!"
Satoru's focus was solely on the Eight-Tails, ignoring the rest.
"GRRRAAAARRR!" The Eight-Tails prepared another powerful attack, forming a Tailed Beast Ball in its maw. The previous one was partial transformation; countering it required Yin Seal release. Now, it was full Tailed Beast form.
"Now I can only tank it head-on," Satoru extinguished Amaterasu and reconcentrated all chakra in his body. Facing the Eight-Tails' Tailed Beast Ball, he showed no fear, trusting his power.
"Run, quick! Can't stay here!" Nearby hidden Cloud ninjas saw the Tailed Beast Ball prep and fled at max speed.
"Perfect Susanoo!" Satoru activated both Mangekyo Sharingans, channeling all chakra into his dojutsu.
Susanoo instantly evolved from third stage to perfect form.
A gigantic Perfect Susanoo in Sage's Cloak appeared.
"Flash Release: Flash Shield!" Satoru created a laser shield before him. "This is my strongest defense right now! My absolute defense! Eight-Tails! You won't breach it!"
The enraged Eight-Tails didn't reply, instead maxing the Tailed Beast Ball and firing it at the young shinobi.
The Tailed Beast Ball ultimately slammed into the Flash Shield, exploding immediately.
*BOOOOOOM!*
Chaos reigned. Everything within kilometers was obliterated.
Satoru was spent too. No strength left. Goro Goro no Mi, Yin Seal, Flash Release, Susanoo... He'd used all trumps, yet the Eight-Tails seemed to have reserves.
"Can't even beat a Tailed Beast? How laughable..."
"No! If this is my limit... I'm too weak!" Satoru, seemingly exhausted, rallied in the next second.
His body instantly reformed into Perfect Susanoo. This time, he squeezed out every last bit of energy.
"Susanoo: Flash Star Core!" Satoru unleashed a star core, birthing devastating force.
At that instant, a figure appeared.
"Hell Stab: One-Finger Strike!"
