The Raikage's tent was a fortress of canvas and steel poles, reinforced like a bunker more than a command center. A dim lantern burned in the corner, casting a golden glow over maps, scrolls, and the enormous silhouette of the Third Raikage. He was pulling on his armor to make an appearance on battlefield when his mind drifted back to a different evening... not so long ago... inside the training yard of Kumogakure.
It was Kaien, little Kaien, bouncing on the balls of his feet, his wiry frame lined with sweat. He had been insistent that day, pestering his grandfather for "real training." Not just chakra control, not calligraphy, but something physical. Something to test himself.
"Muay Thai, jii-sama!" Kaien had shouted, fists raised high, elbows tucked in awkwardly. "The art of eight limbs. I tried to improvise after reading it in a scroll, and it's awesome! Fists, elbows, knees, shins... you can't stop all of it!"
The old Raikage had raised one thick brow, then folded his arms across his chest. "Eight limbs - fists, elbows, knees, and shins. Is that the idea?"
Kaien grinned, his teeth white in the sunlight. "Exactly. Let's see if the wall can hold up!"
The boy had charged in, throwing a flurry of clumsy strikes. A jab, a low kick, an elbow meant to smash into the Raikage's chest. The old man hadn't moved. Every strike hit solid flesh like striking a mountain. Kaien's shins throbbed, his fists ached, his elbows scraped, but he didn't stop. He moved like he'd studied... turning hips, snapping knees, chaining attacks.
Finally, panting and drenched, Kaien leaned against his knees. "You didn't even budge," he muttered.
The Raikage finally cracked a smile. He reached out, rested his massive palm on Kaien's small, sweat-soaked head. "You're improving. Not because you can't hurt me... But because your body and your mind are beginning to move together. You see the strike before you throw it. You shift weight before the limb extends. That coordination, boy... that's what makes a shinobi."
Kaien looked up, wide-eyed. "So… I'm good?"
"You're better," the Raikage said. "And one day, you'll be the wall. Strong enough to hold everyone behind you."
The boy mumbled to himself "The wall...huh..."
The memory faded as the Third Raikage tugged his gauntlets into place, his jaw set. That boy's instinct... the same instinct that had warned about the Yellow Flash, about Kushina, about the Hokage's movements... was sharper than most veterans. He wasn't wrong. Konoha had unleashed both their jinchūriki and their prodigy in the same battalion, it meant they were serious.
The Raikage stepped out of the tent, the morning air bracing against his chest. The art of eight limbs...huh...

On the battlefield, kunai glinted like falling stars. Minato Namikaze moved faster than the eye, each flicker of light a teleportation, each strike deadly. He cut down two more earth-style shinobi who tried to bury his weapons underground. Their hands hadn't even finished their seals before he was behind them, his kunai slicing precise and final.
Dodai, though, was different. He had covered his body in a thick rubber coating, layers of hardened chakra-infused latex that blunted Minato's kunai and absorbed the shock of surprise teleportations. Every time Minato appeared, blade flashing for the seal, Dodai twisted, the rubber bulging, stretching, making it impossible for Minato's blade to find flesh.
Minato narrowed his eyes as he disengaged, landing light on the ground. His mind calculated rapidly. I need to tag him. A seal on his body ends this. But the rubber… he's padding himself perfectly. Even a direct stab only sinks halfway.
His hand moved instinctively to a fresh kunai, chakra already searing the Flying Thunder God mark onto the handle. He could plant the seal manually, yes... but that meant making direct contact, palm to skin, in the middle of a battlefield where every second counted. Dangerous. Risky. Not his style unless he was aiming for a killing blow.
Dodai smirked from behind his defenses, sweat dripping but his stance strong. "Your speed's wasted, Yellow Flash. Can't pierce rubber, can't pierce me. You're fast, i can't react to your strike but i have layers of rubber protecting me all the time."
Minato darted in again, flickering from kunai to kunai, probing Dodai's defenses. Each time, Young Ay was there... his body a blur of lightning chakra, intercepting Minato's path, forcing him off balance. Minato could feel it, the coordination. Ay was buying Dodai seconds at a time, and Dodai was turning those seconds into survival.
The Severed Link. Then, it happened.
Minato reached mid-stride for his mark... the special Flying Thunder God seal he had left on Kushina's chakra before the battle. It was his anchor, his safety line to her. His failsafe. But the connection… was gone.
The tether snapped in an instant. One moment it was there, steady and burning at the edge of his senses, and the next it was silence.
Minato froze. His heart clenched. Kushina…? is she dead? even if she is dead, i should be able to sense the FTG mark. So, She must be sealed.
A roar built in his chest, fury burning hotter than any fire. His body blurred with speed, kunai scattering in a furious storm around Young Ay.
Ay laughed, lightning crackling across his shoulders. "What's wrong, brat? Losing focus?" He charged, meeting Minato head-on, sparks splitting the air as kunai clashed against lightning armor.
Minato's strikes lost their surgical precision. They became wild, furious, each teleportation less controlled than the last. His golden hair whipped in the wind as his kunai slashed furiously, but Young Ay's armor held, Dodai's interference cutting off his cleanest kills.
For the first time, Minato fought with RAGE.

The ground quaked. A shadow blotted out the stars.
Minato flickered sideways just in time to avoid a crushing fist the size of his torso. The earth exploded where the blow landed, a crater blooming in the soil. Dust and fire shot into the sky.
Standing at the edge of the crater was the Third Raikage. His massive frame glowed with lightning armor, thicker and brighter than anything Ay had conjured. His eyes were steady, cold, unshaken by the chaos of battle.
"You are the Yellow Flash," he said simply, voice rumbling like thunder across the battlefield. "Good. I was hoping to test my speed against your teleportation."
Minato's eyes widened. His breath came ragged, but he set his jaw. So he's come himself… The Raikage didn't wait for an answer. He blurred forward, his speed monstrous for his size and faster than his son, closing the gap before Minato could even blink. The air burned with electricity.
Their clash split the battlefield.
