Since Satoru was using this technique for the first time, he hadn't fully mastered it yet, so the attack speed wasn't as high as he'd like.
Many enemies dodged the light beams using Earth Release or other defensive jutsu.
Of course, some unlucky ones got hit. Those struck by the technique were instantly obliterated. Satoru's Flash Release combined Lightning Release's piercing power with Wind Release's cutting force. In offense, it resembled a laser beam; in defense, a laser shield.
"Flash Release? Never heard of such an element... Looks like the enemy's a Kekkei Genkai user... No wonder he's so strong!" The Cloud ninjas now fully realized how dangerous Satoru was.
"Don't give up! Charge!" Blue Bee shouted, regaining his balance and rushing back into the fray. Satoru targeted him again with Wave of Chaotic Light.
If last time the Wave of Chaotic Light was scattered across multiple ninjas, this time it focused solely on Blue Bee. A single moment's hesitation from the Eight-Tails jinchuriki, and Satoru could finish him.
At first, Blue Bee dodged effectively. But as Satoru grew more proficient, the Wave of Chaotic Light's speed increased. Soon, Blue Bee couldn't keep up.
"Damn! His speed keeps rising! This won't do! Attack him!" the jinchuriki yelled.
The remaining Cloud ninjas attacked Satoru immediately. The youth had no choice but to halt the technique. Blue Bee got lucky being saved.
"Flash Release: Flash Clones!"
"Wave of Chaotic Light from the Clones!"
First, Satoru created several Flash Clones using his Flash Release chakra. Then, through these clones, he unleashed countless homing Waves of Chaotic Light at the enemies. The speed of these light attacks was already very high, and their number surged. In an instant, several Cloud ninjas' bodies were pierced through.
Some quicker Cloud shinobi shifted at the last moment to avoid vital organs. But the Wave of Chaotic Light paralyzed them instantly.
In the end, only a few ninjas and Blue Bee himself remained, desperately fending off the relentless assaults.
"Eight-Tails! Lend me your power! Otherwise, I'm done for!" Blue Bee was in a critical spot. The Eight-Tails Gyuki, seeing this, naturally couldn't stand by. After all, he fully acknowledged Blue Bee as his jinchuriki.
At the last moment, Satoru's Wave of Chaotic Light wiped out the remaining Hidden Cloud ninjas. Only Blue Bee survived.
By now, he had borrowed the Eight-Tails' chakra. His body was cloaked in red chakra, but this wasn't the full Tailed Beast Cloak—just the first stage of using bijuu red chakra.
"Using the Eight-Tails' chakra, huh? Interesting. But in that state, you're no match for me with Flash Release. I suggest you go full Tailed Beast transformation right away," Satoru said, eyeing his opponent.
"Don't worry, even like this, I'll tear you apart easily!" Blue Bee charged at Satoru. This time, his speed and power had surged dramatically.
Satoru watched with interest, swiftly forming seals. "Flash Release: Flash Wall!"
A laser wall rose right in front of Satoru. Blue Bee didn't crash into it but leaped up and hurled the sword he carried on his back.
"I've never seen a fighting style like this," Satoru thought, spinning his Diamond Staff.
"Extend!" The Diamond Staff rapidly lengthened, seeming about to strike Blue Bee. But the jinchuriki grabbed it, using it as leverage to flip through the air straight at Satoru.
"Very agile. Like a mini Tailed Beast," Satoru was moments from close combat, but he feared such situations least.
Close quarters was Blue Bee's strength, yet Satoru dodged all his attacks with astonishing ease.
"Armament Haki: Monstrous Strength!" With one strike, Satoru repelled Blue Bee. Immediately after, he swung the still-extending Diamond Staff!
This time, it slammed into Blue Bee's chest, hurling him even farther.
"GRRRAAAARRR!" Perhaps displeased with his jinchuriki, Blue Bee's body instantly shifted to partial Tailed Beast transformation. His entire form turned crimson.
"Perfect. I wanted to test if I can stand against a Tailed Beast now," Satoru gave Blue Bee ample time to transform. Eight tails fully burst from the jinchuriki's back, a bony exoskeleton covered his body, and immense chakra erupted from him.
A massive shockwave arose! Blue Bee's Tailed Beast transformation was far stronger than Satoru expected!
Even from a distance, Satoru felt the terrifying power emanating from Blue Bee.
"Such chakra level... monstrous... Driving the Eight-Tails berserk... I might not want to live..." Seeing Blue Bee fully overtaken by the Eight-Tails, Satoru stepped forward. He was the only one who could stop the rampaging jinchuriki now.
Blue Bee, naturally, saw Satoru as his primary foe.
"GRRRAAAARRR!" Blue Bee roared, and the surrounding terrain shattered from the shockwave.
"Terrifying! But this time, I strike first!" Satoru no longer probed the Eight-Tails' power. He activated the Goro Goro no Mi fruit's abilities at once.
"Two Hundred Million Volts: Raijin!" Satoru instantly took Raijin form, his body cloaked in maximum-power lightning.
*BOOM! BOOM! BOOM!*
In Raijin form, Satoru assaulted the Eight-Tails head-on. The mini Eight-Tails was very nimble, leaping side to side, dodging all of Satoru's strikes.
"GRRRAAAARRR!" The Eight-Tails formed a Tailed Beast Ball in its maw and fired it swiftly at Satoru.
"Flash Release: Flash Star Core Wave!" Satoru concentrated Flash Release energy in his hand, then unleashed it as a powerful stream. The Tailed Beast Ball collided rapidly with the Flash Star Core Wave energy.
The surroundings changed again. A gigantic explosion erupted!
Satoru felt intense fatigue. Flash Release consumed far more chakra than Wind or Lightning Release. Though he repelled one Tailed Beast Ball, he knew a prolonged fight would wear him down.
As if on cue, the opposing Eight-Tails began firing serial Tailed Beast Balls one after another.
Satoru had no choice. The Tailed Beast Ball's power was immense; he couldn't tank a direct hit, so he countered attack with attack.
Thus, mimicking the serial Tailed Beast Balls, Satoru unleashed serial Flash Star Core Waves. Though he blocked the Eight-Tails' assaults, Satoru was at his limit.
*WHOOSH!*
The Eight-Tails Blue Bee wasn't foolish. Noticing Satoru's depleting chakra, it instantly formed a gigantic Tailed Beast Ball. This one dwarfed the previous. Satoru knew winning this clash would likely win the fight. Failing to block it meant certain death.
"Looks like it's time for that technique..."
"Yin Seal: Release!"
Satoru's chakra was nearly gone, but he had far more stored in his body. All that unabsorbed chakra resided in his Yin Seal.
