As Mitsuya's companions lay defeated and the once vibrant worlds they had visited now stood as desolate wastelands, a twisted grin formed on Mitsuya's face. The taste of victory mingled with the darkness that had consumed his soul, fueling his insatiable thirst for power.
Word of Mitsuya's triumph spread throughout the cosmos, striking fear into the hearts of all who heard it. Planetary leaders, intergalactic organizations, and even cosmic beings themselves cowered before his might, realizing that their only hope lay in submission to his rule.
With Ten Tails Claws pulsating with corrupted energy, Mitsuya ascended to the pinnacle of his power, his form enveloped in an aura of malevolence. He reveled in his newfound strength, using it to reshape entire galaxies to his twisted desires, molding them into extensions of his dark will.
The once defiant whispers of resistance were silenced, crushed under the weight of Mitsuya's overwhelming dominance. Those who had once stood against him now trembled, their spirits broken and their hopes shattered. They were forced to bend the knee, their worlds enslaved and their freedom snuffed out.
Mitsuya's reign of darkness extended to every corner of the shattered cosmos, his influence unchallenged. He reveled in the chaos and despair he had created, delighting in the suffering of those who had once dared to oppose him.
With his dominion established, Mitsuya turned his attention to the remnants of his former companions. They sought refuge on the secluded planet of Lumina, believing it to be a sanctuary hidden from his sight. Little did they know that Mitsuya's power had eclipsed their feeble attempts to hide.
Tracking their every move, Mitsuya unleashed a devastating assault upon Lumina, obliterating the planet and its inhabitants with a single stroke of his corrupted power. The remnants of his former allies were torn asunder, their defiance extinguished forever.
Rei, the last remaining survivor of the companions, witnessed the destruction of Lumina from afar. Her heart sank, for she had hoped against hope that they could prevail against Mitsuya's darkness. Now, she stood alone, the weight of her failure pressing upon her weary soul.
Mitsuya, his victory complete, appeared before Rei, his form radiating with a perverse delight. "Did you truly believe you could stand against me, Rei?" he sneered, his voice dripping with contempt. "Your companions were fools to challenge my power. And now, you are the last ember of hope, waiting to be extinguished."
Rei, her spirit battered but unbroken, met Mitsuya's gaze with defiant eyes. She refused to succumb to despair, refusing to let her last glimmer of hope be snuffed out. With a trembling voice, she spoke, "You may have won this battle, Mitsuya, but the fight for light and justice will never end. As long as there are those who remember the true nature of heroism, your reign will always be challenged."
Mitsuya's laughter echoed through the desolate landscape, his amusement at Rei's futile resistance palpable. "Challenge me all you want, Rei. It matters not. Your defiance is but a fleeting moment in the vastness of eternity. I am the darkness that will forever overshadow your feeble light."
With a wave of his hand, Mitsuya unleashed a final surge of dark energy, engulfing Rei and erasing her presence from the universe. Her defiant spirit was extinguished, leaving only the lingering echoes of a valiant but futile struggle.
And so, Mitsuya stood alone, a god among mortals, his dominion unchallenged. The shattered cosmos remained under his oppressive rule, forever trapped in the suffocating embrace of his darkness. The universe itself wept for the loss of hope and the triumph of eternal night.
