In the arena of ever-changing landscapes in an unknown location in the JJK Universe, the two Ryomen, Meguna and Sukuna, faced off in a fierce battle to the death. As the veil of magic enveloped the arena, both combatants brought forth their Malevolent Shrines, ready to unleash their power. Sukuna cracked his neck and grinned, eyes sparkling with malevolent glee. "You think you can take me on, old man?" he sneered, his four arms flexing menacingly. Meguna didn't answer, but the air around him crackled with power as he activated his Reverse CT, instantly regenerating his body. He held out his hand, and a shimmering mahoraga materialized, ready to adapt to any attack. Sukuna let out a roar and charged at Meguna, his blades flashing in the dim light. But Meguna was too quick for him, his footwork expertly dodging each strike. He retaliated with a swipe of his hand, unleashing his default slashing attack, Dismantle, and Sukuna barely managed to block it with his own blade. "You're not bad," Sukuna growled, his eyes narrowing. "But let's see how you handle my Fuga!" He raised his arm, and a powerful fire arrow shot towards Meguna. Meguna smirked and simply raised a hand, causing the arrow to fizzle and die before it could reach him. "You'll have to do better than that," he taunted. Sukuna snarled and charged again, his blades a blur of motion. Meguna dodged and weaved, waiting for his moment. Finally, he saw his opening and unleashed his World Cutting Slash, a chanting 4D dimensional slashing attack that sliced through space itself. Sukuna barely managed to dodge, but the attack left him staggering. "You...you're stronger than I thought," he gasped, clutching his chest. "Of course I am," Meguna replied coolly. "I am the King of Curses, after all." He gestured towards his Malevolent Shrine, and the air around him began to shimmer. "But perhaps you want to see what else I can do?" Sukuna's eyes widened as Meguna's Wheel of Dharma began to spin, taking damage so that the mahoraga could adapt to any attack. With a fierce howl, Sukuna charged once more, his blades whirling. But Meguna was ready for him. He unleashed his Merge Beast Agito, and the mahoraga shifted and morphed into a powerful beast, ready to defend its master. With a mighty swipe, Meguna's Cleave sliced through Sukuna's guard, leaving him defenseless. Sukuna stumbled back, his breathing ragged. "How...how can you be this strong?" he gasped. Meguna simply smiled. "I have lived for a thousand years, my power is immeasurable," he replied. "And now it's time for you to face the consequences of attacking the King of Curses." He raised his hand, and his Female Deer Shikigami began to glow with an inner light. With a gentle touch, the Shikigami began to heal Meguna, restoring him to full strength. "Thank you, my friend," Meguna murmured. Sukuna snarled and raised his blades once more. "I won't go down without a fight!" he roared. Meguna simply shook his head. "You should learn when to quit," he replied. With a flick of his wrist, his Malevolent Shrine unfolded, dismantling and cleaving Sukuna relentlessly in a 200m radius. Sukuna let out a final scream of pain before collapsing to the ground, defeated. Meguna stood over him, watching as his lifeblood pooled on the ground. "It's over," he said softly. "Rest in peace, Ryomen Sukuna." As he turned to leave, his mahoraga at his side, Meguna couldn't help but feel a twinge of sadness. It was always a shame when someone had to die, especially in a senseless battle like this. But in the end, he had won, and that was all that mattered.
