Void Shatters the Boundary and Enters the Shinobi World; the Three-Color Seal Battles Gen's Army

At the Allied Forces of the Five Great Nations' camp, Naruto rubbed his aching eyes from atop the watchtower. The golden pupils formed by Nine-Tails Chakra remained fixed on the horizon. The black mist left behind when Gen vanished three days ago had yet to dissipate completely. It had formed a warped gray curtain along the border of the Land of Fire, like a man-eating beast lurking at the edge of the Shinobi World.

"Any sign of movement?" Sasuke landed on the watchtower railing, the golden Power of the Fire Seed flickering at his fingertips and driving away the chill. He had just returned from the Uchiha ancestral grounds. The scroll clutched in his hand was covered in dense annotations beside the diagram of the Three-Color Rinne Void Seal. They were his additions to the advanced technique, based on the secret text of the Uchiha Stone Tablet.

Naruto shook his head. The Tailed Beast Chakra gathering at his fingertips turned into a golden streak of light and flew toward the gray curtain. The moment it touched the curtain, it was swallowed whole without making even the slightest ripple. "Something's wrong. Gen said the Void Realm's army would arrive soon, but it's been too quiet for three days. The silence is unsettling."

Su Ye's voice came from behind them. His Rinne Sharingan turned slowly, its pale purple glow piercing the tents as he gazed into the depths of the gray curtain. "It's not quiet. They're gathering strength. Gen's true body is reorganizing his army in the Void Realm. He's waiting for a chance to break through the spatial barrier in one decisive strike." He raised a hand and infused the scroll in Sasuke's grasp with a thread of Rinnegan power. The symbols on the diagram suddenly lit up, resonating with the three men's chakra and projecting a three-dimensional map of the Shinobi World into the air. Every spatial node along the Land of Fire's border was clearly marked.

Just then, the ground shook violently. The alarm bell atop the watchtower rang out with a piercing roar, and hurried footsteps immediately echoed through the camp. The Raikage flashed past the tents, Lightning Release chakra crackling around him. "They're here! The spatial barrier at the Land of Fire's border has been torn open!"

The three immediately flew toward the border. Along the way, countless Allied Forces shinobi were gathering in the direction of the gray curtain. Gaara manipulated Iron Sand to raise a massive defensive wall. Tsunade led the medical shinobi in setting up a temporary medical station behind it. Sage Fukasaku directed the Toad Army from Mount Myoboku as they formed a Senjutsu barrier in the sky.

When the three reached the border, the sight before them made their pupils contract. The gray curtain had vanished, replaced by a massive spatial rift. Black mist poured from it in an endless stream, and countless twisted figures leaped out. The Void Soldiers had no physical bodies; they were like flowing shadows, wielding weapons formed from black chakra as they charged the Allied Forces' position.

"Everyone, follow the plan!" Su Ye shouted. He channeled his Rinnegan power, forming a huge spatial vortex of pale purple chakra that sucked in the Void Soldiers at the forefront. Sasuke, meanwhile, wielded a golden-flamed sword and darted among the Void Soldiers like a phantom. Each time his sword swept past, golden flames clung to them with a sizzling sound, purifying them completely.

Naruto entered Nine-Tails Mode. The golden Tailed Beast Chakra formed a gigantic fist that he hurled toward the spatial rift. It collided with the black mist with a thunderous boom. The shock wave sent the surrounding Void Soldiers flying, but the rift remained untouched. Even more Void Soldiers poured out.

"This isn't working!" Naruto roared as he gathered a Tailed Beast Bomb. Just then, a low horn sounded from within the spatial rift. At its call, every Void Soldier stopped attacking and retreated to either side. A huge shadow slowly emerged from the rift: a Demon Eater Lord, as massive as a Tailed Beast. Its body was formed from pure black mist, and two enormous horns grew from its head. Crimson light gleamed in its eyes.

The Demon Eater Lord opened its mouth and fired a black beam toward the Allied Forces' position. Gaara immediately manipulated Iron Sand to raise a thick wall of sand in front of the formation. But the black beam pierced through it with ease and streaked toward the medical station. At the last possible moment, Tsunade leaped into the air, gathered pure chakra in her hands, and caught the beam head-on. The tremendous impact brought blood to her lips, but she gritted her teeth and held on, redirecting the beam into the sky.

"Sasuke, Naruto, with me!" Su Ye shouted. The three flew toward the Demon Eater Lord together. Su Ye channeled his Rinnegan power, forming a spatial cage of pale purple chakra around it and temporarily trapping it. Sasuke gathered the Power of the Fire Seed into a huge flaming sword and slashed at the Demon Eater Lord's horns. Naruto entered Six Paths Mode, merging golden chakra with Tailed Beast Chakra to form a gigantic Tailed Beast Bomb in his hands, then hurled it at the Demon Eater Lord's belly.

"Boom!" All three attacks struck the Demon Eater Lord at once. The golden flames set the black mist ablaze, the Tailed Beast Bomb exploded against its belly, and the spatial cage continued to contract, trying to seal it completely. But the Demon Eater Lord roared and unleashed a tremendous force of void energy, shattering the cage. It swung its head, charging at the three with its enormous horns.

Su Ye immediately used Space-Time Ninjutsu to teleport himself, Sasuke, and Naruto behind the Demon Eater Lord. Watching its wounds continually repair themselves, he furrowed his brow. "Its recovery is too strong. Ordinary attacks won't work. We have to use the Three-Color Rinne Void Seal and strike directly at its core!"

Sasuke nodded, gathering the flames of his sword once more. "I'll keep it occupied. Get the Sealing Jutsu ready." He flashed toward the Demon Eater Lord. The golden-flamed sword swept through his hands, sending wave after wave of fiery blades slashing toward it. Naruto entered Nine-Tails Mode, the golden chakra around him surging. He leaped into the air and punched toward the Demon Eater Lord's head.

Su Ye took a deep breath, and his Rinne Sharingan suddenly blazed. Pale purple chakra swirled around him, resonating with Sasuke's golden Power of the Fire Seed and Naruto's Tailed Beast power. Three pillars of differently colored chakra converged in the sky, forming a massive three-colored vortex. It spun faster and faster, warping the space around it.

"Now!" Su Ye roared, sending the three-colored vortex toward the Demon Eater Lord. The moment it touched the creature, it erupted in dazzling light. The Demon Eater Lord let out a shrill scream as its body began to fade away. But just then, another horn sounded from within the spatial rift. A dark golden figure leaped out—it was Gen's true body.

Gen raised a hand, sending a chain formed from black chakra flying toward the three-colored vortex. The chain wrapped around the vortex and dragged it forcibly to one side. The Demon Eater Lord seized the opportunity to break free, and its body quickly repaired itself. Gen gave a cold laugh as he looked at Su Ye and the others. "Last time, you only managed to drive me back by sheer luck. You won't be so fortunate this time."

He channeled his void energy, and the black mist around him gathered into a massive demonic sword. Gripping it, Gen slashed at Su Ye. Su Ye immediately used Space-Time Ninjutsu to teleport behind him. But Gen had anticipated the move; he swung his sword back at Su Ye. At the last moment, Sasuke and Naruto struck together. Sasuke's golden-flamed sword blocked the attack, while Naruto punched Gen in the stomach.

Naruto's punch sent Gen staggering several steps backward. He looked at the three, surprise flashing in his eyes. "I didn't expect your strength to have improved so much in just a few days. But it's still not enough!" He raised a hand, and countless spears formed from black chakra shot toward them. At the same time, more Void Soldiers and Demon Eater Lords poured out of the spatial rift, charging toward the Allied Forces' position.

"Allied Forces, heed my command!" The Raikage's voice rang across the battlefield. "First division, hold back the Void Soldiers! Second division, support the Tailed Beasts in attacking the Demon Eater Lords! Third division, protect the medical station and the rear position!" At his command, the Allied shinobi sprang into action. Countless ninjutsu attacks flew toward the Void Soldiers, while the Tailed Beasts launched their own assault, sending wave after wave of Tailed Beast Bombs at the Demon Eater Lords.

Su Ye, Sasuke, and Naruto fought Gen fiercely. His strength far surpassed that of his previous clone. His void energy could not only devour chakra but also warp space. Gen repeatedly countered Su Ye's Space-Time Ninjutsu. Sasuke's golden flames could barely hold back the demonic sword, while Naruto, even in Six Paths Mode, could do no more than match Gen.

"This won't work!" Su Ye shouted. "We have to activate the Three-Color Rinne Void Seal together if we want a chance to defeat Gen." Sasuke and Naruto nodded. They exchanged a glance and channeled their chakra at the same time. Pale purple, golden, and orange-yellow chakra converged once more, forming a three-colored vortex even larger than before.

Gen's expression changed when he saw it. He channeled all his void energy, making the light of his demonic sword burn even brighter. "I won't let you do it!" Gripping the sword, Gen slashed at the vortex. The sword collided with it with a resounding boom. The shock wave sent the surrounding Void Soldiers and Demon Eater Lords flying, and the entire battlefield shook violently.

"Hold on!" Su Ye roared, pouring more of his Rinnegan power into the attack. Sasuke and Naruto added their strength as well. The three-colored vortex grew stronger and gradually overpowered the demonic sword. Gen's body began turning transparent, and a trace of unwillingness flashed in his eyes. "I refuse to accept this! The Void Realm's army is endless. Even if you defeat me, you still won't be able to stop them!"

Just then, the Tailed Beasts' voices rang out in the three men's minds. "We'll help you!" All nine Tailed Beasts poured their chakra into the three-colored vortex. Their chakra merged with the trio's, and the vortex's power surged in an instant. It swallowed the demonic sword completely, then hurtled toward Gen.

The three-colored vortex struck Gen. His body let out a thunderous boom and vanished completely. The black mist within the spatial rift gradually dissipated. With their source of power gone, the Void Soldiers and Demon Eater Lords collapsed to the ground.

The three collapsed onto the ground, their chakra completely depleted. The Allied shinobi cheered when they saw them. The Raikage walked over and patted them on the shoulders. "Well done! You've driven back the Void Realm's army."

Su Ye shook his head, watching the spatial rift slowly close. "Gen may have been defeated, but the Void Realm is still there. As long as the spatial rift isn't sealed completely, they could invade again at any time. We have to perfect the Three-Color Rinne Void Seal as soon as possible and seal the Void Realm for good."

Just then, Sage Fukasaku landed in front of the three. "I know a way. Mount Myoboku's Senjutsu source can strengthen the power of the sealing technique. If we infuse it into the Three-Color Rinne Void Seal, we can seal the spatial rift for good."

The three brightened. Su Ye stood up, determination shining in his eyes. "There's no time to lose. We're heading to Mount Myoboku now. This time, we'll protect the Shinobi World once and for all!"

The three then followed Sage Fukasaku to Mount Myoboku. With Gamamaru's help, they successfully infused the Senjutsu source into the Three-Color Rinne Void Seal. When the three returned to the Land of Fire's border, the spatial rift had not yet fully closed. They immediately activated the sealing technique. The three-colored vortex merged with the Senjutsu source, forming a vast barrier that sealed the spatial rift completely.

With the spatial rift closed, the Shinobi World finally returned to peace. The leaders of the Five Great Nations gathered at the Allied Forces' camp to hold a grand victory banquet in honor of Su Ye, Sasuke, and Naruto. At the banquet, Tsunade looked at the three with heartfelt relief. "From this day on, you're heroes of the Shinobi World."

Su Ye, Sasuke, and Naruto exchanged smiles. They knew this wasn't the end, but a new beginning. The Shinobi World had returned to peace for now, but more challenges awaited them in the future. They would continue to stand together and protect the land they loved.
