Naruto and Goku stared at each other, ready to clash again. Their energy grew stronger and stronger. The island below cracked and shook. Even the air could not handle their power. Lightning flashed all around them, created from their energy alone.
Just as they prepared to charge, a sharp voice echoed from the sky:
"STOP THIS FIGHT RIGHT NOW!"
A bright blue portal opened, and two shadows stepped out. The portal closed behind them like a door sealing a dangerous secret.
Naruto narrowed his eyes. "Who are they…?"
One man wore a long black cloak with a red cloud symbol. His eyes were powerful, spinning like a storm.
Naruto's heart dropped.
"Itachi…?"
The other figure floated beside him — tall, calm, and strong. He had blue skin, long white hair, and a halo ring behind his back.
Goku gasped. "Grand Priest?! Why are you here!?"
Both warriors from two worlds looked serious. No smiles. No jokes.
Itachi spoke first. "Naruto. This battle is not a normal fight."
Grand Priest continued, "If you two keep fighting at full power, your energy will tear your worlds apart. Not one world… but both universes."
Naruto and Goku were shocked.
Goku scratched his head, confused. "Really? It's just a friendly fight…"
Grand Priest's voice was stern. "Even a friendly fight between gods can create destruction. You both reached a level where even small mistakes can destroy reality."
Naruto felt Kurama's chakra calm down inside him.
Itachi stepped closer. "Naruto, you have become very strong. But Kurama's power and Sage power together… they are equal to a god."
Naruto looked at his fists. "I never wanted to destroy anything… I only want to protect."
Goku looked a little sad. "I just wanted a good match…"
But then Grand Priest's eyes turned sharp.
"But there is something far more dangerous happening."
Both fighters listened carefully.
"There is a hidden power watching this fight. A villain who wants your battle to break the walls between universes."
Naruto frowned. "Who would want that?"
Itachi looked toward the horizon. His Mangekyo Sharingan glowed.
"A creature who can feed on chaos. A being who wants to combine both worlds into one playground of destruction."
Naruto and Goku stood side by side now — not as enemies, but as allies.
Goku asked, "So what should we do?"
Grand Priest raised his hand and created a glowing cube made of light.
"This is a dimensional lock. It will keep your powers inside a safe battlefield. You can finish your fight there — without any danger to universes."
Naruto looked uncertain. "Should we still fight? If a villain is coming—"
Grand Priest shook his head. "You must fight. The villain wants your energy. If you stop now, he will attack when you are weaker."
Naruto and Goku looked at each other again. But now, their eyes did not show rivalry. They showed respect.
Goku smiled warmly. "Naruto… let's finish this the right way."
Naruto returned the smile. "Yeah. A true fight — warrior to warrior."
Itachi placed a hand on Naruto's shoulder.
"I believe in you. Show the strength of our world."
Naruto nodded with emotion in his heart.
Grand Priest placed his hand on Goku's shoulder.
"I trust you. Do not hold back."
Goku clenched his fists. His Super Saiyan Blue aura burst again, bright and powerful.
Naruto summoned Kurama's power — golden flames surrounded his body like a sun ready to explode.
The cube of light opened like a gate. Inside was a new arena — dark sky, broken rocks, and endless space.
This was their battlefield now.
Before stepping inside, Naruto looked behind.
"Itachi… thank you."
Itachi gave a small smile. "Win."
Goku looked at Grand Priest. "Don't worry. We'll make this awesome."
The gate closed after they entered. The arena rumbled with pure energy.
Naruto and Goku faced each other once more.
"No worlds will be hurt now," Naruto said.
"Then let's go all out!" Goku shouted with excitement.
Their auras rose high… shaking the entire dimension.
But above them, hidden in the shadows…
someone laughed.
A cold, evil laugh.
The real danger was just beginning.
