The Sword of the Universe descended into Ken's hands, radiating a divine aura. Light spilled from its blade, cutting through the surrounding darkness, and the hum of its power vibrated through the very air. This was no ordinary sword—it was sharp enough to slice through the cosmos itself. With the Ring of Elements on his finger and the sword in his grasp, Ken felt the flow of energy surge through him. The air around him seemed to warp; gravity, sound, and even time itself trembled under the pressure of his power.
The Dark Dragon sensed the shift. Its crimson eyes glowed with fury as it launched a massive attack, sending a shockwave through the battlefield. Ken gritted his teeth and raised the Sword of the Universe. The impact of his counterattack reverberated through his arms, tearing at his muscles. Pain shot through his hands. His legs trembled. Each breath felt like inhaling shards of glass.
But he remembered.
"Never break your promise. Always keep your word." His father's voice echoed in his mind.
His friends, Lexus, Professor Rex, Lana, Art. Their faces flashed before him. The lives of everyone depending on him.
A single drop of sweat ran down his temple. A bead of saliva escaped his mouth. He whispered to himself, barely audible over the roar of the Dragon:
"Alright… here I go."
The Dragon bellowed, wings flaring, shaking the very stars around them. "Come, child. If you think you can face me!"
They collided at impossible speed. Fists clashed. Shockwaves rippled across the universe. Stars blinked hundreds of times in a second. The intensity of the battle made time feel fractured.
Ken focused, channeling the ring's power. Flames erupted from his sword in a swirling Fire Vortex, attempting to trap the Dragon. The creature's powerful wings sent the vortex spiraling back at him. Reacting instinctively, Ken summoned a Water Vortex, neutralizing the flames. The Dark Dragon grinned, unleashing Universal Pull, dragging Ken toward its maw. Gravity bent, darkness consumed him. His vision vanished.
For what felt like an eternity, Ken was blind. Attacks struck from all directions. He dodged by relying on his instincts and the ring's faint whispers. The Dragon's fist morphed into Death Claw, then into a massive Death Punch, hitting him squarely. Pain exploded through his body, but in that impact, his sight returned.
Ken's legs wobbled. His arms screamed in pain. Yet in the chaos, a single thought anchored him: I cannot fail. I must fight.
Summoning his will, Ken channeled Elemental Fist into the sword, creating the Elemental Slash of the Divine Sword. A blinding arc of power struck the Dark Dragon, staggering it backward. But the beast's attacks accelerated, faster than ever before. Ken realized he had no time to prepare sword techniques anymore—it had become pure, unrelenting hand-to-hand combat. Every strike landed, every blow exchanged felt like shaking the foundations of the universe.
Then, taking a deep, shaky breath, Ken summoned the full might of his elemental powers:
Fire Phoenix, wings ablaze, screaming in flames.
Water Leviathan, tidal fury crashing against the Dragon.
Earth Golem, fists of stone pounding relentlessly.
Thunder Dragon, lightning shredding the darkness.
Beast of Frost, icy breath freezing even the shadows.
Divine Dragon of Light, born from the purity of Ken's heart, radiating hope and courage.
Every elemental attack surged through his body, flowing from the ring to the sword. Light and fire, ice and water, earth and thunder—an unstoppable torrent. With one mighty strike, he hit the Dragon squarely, sending it crashing to its knees.
Across the universe, gods and the Seven Star Lords felt the shockwaves. They exchanged worried glances. Even the mighty elemental dragons noticed the power of Ken's strike.
The Dark Dragon coughed, blood and shadow spilling from its maw. "Do you think it will be that easy? I… was never meant to exist. I am a byproduct of destruction itself. Neither god, nor demon—only rejection, only solitude. They sealed me in this eternal darkness, cast me aside. I was never accepted."
Its aura erupted, a monstrous force of pure destruction. Dark energy spiraled around it like a storm, threatening to tear the battlefield apart.
Ken's legs shook. His heart raced. Every fiber of his body screamed to retreat. The Dark Dimension seemed too heavy to hold. He pressed a trembling hand to the sword and whispered, "For the universe… for my promise… I stand."
The Dragon roared, morphing into its ultimate form. Its presence alone warped the very dimension, bending light and shadow.
The final clash began.
Ken used Lexus's ultimate technique: Ten-Directional Slash. The sword struck from ten angles at once, tearing into the Dragon. But the beast endured, countering with stolen powers from the Four Eternal Dragons—Death, Void, Devil, and End.
Death Ray scorched the air.
Evil Slash carved shadows.
Void Annihilation threatened to erase everything in its path.
End Beam split the ground beneath Ken.
Each attack felt like the universe itself was collapsing. Ken barely survived, using Lexus's Dimension Rift to retaliate. Every strike he dodged required every ounce of skill and willpower he had.
Then came the worst—the Eternal Darkness. The Dragon's most dreaded ability consumed Ken in a void of grief and despair, draining his very will to live. Shadows whispered, urging him to surrender. His body collapsed. His mind wavered.
Meanwhile, the elemental dragons fought the elites. Rex and Lexus battled tirelessly against the horde. Lana and Art defended the cities, pushing back with all their might.
Zevan: "Do you think you can defeat that entity…?" (he stops mid-word, his gaze flicking away)
Lana and Art didn't fully catch it.
Inside the darkness, Ken felt whispers of the sword, the ring, and his loved ones. Then came a strange voice:
"Nice move from my side, brother."
Ken's aura erupted in brilliant light. Willpower, memories, and courage surged through him like a blazing sun. The darkness shattered.
The Dragon recoiled, terrified. "What—what is this?"
Ken's voice was calm, yet full of conviction. "This… is the power of will."
With sword and ring united, Ken unleashed the Universal Destruction Slash. The attack cut through the Dark Dragon, ending its existence in a flash of divine light.
As the Dragon faded, Ken whispered, "You weren't evil… just broken. I hope you find peace… wherever you go."
The Dark Dragon's army, the elites, and shadow creatures vanished.
The gods, Star Lords, Lexus, Rex, Lana, and Art all stared in awe.
"A mortal…" one Star Lord murmured. "A mortal has done what even gods could not."
For a fleeting moment, the Dark Dimension seemed at peace.
But far away, in the deepest shadows, a new seal cracked. A darker force stirred.
Ken's eyes scanned the darkness. "Father! Where are you?"
The calm was temporary. The next storm was already rising.
