As Ace Kurotsuchi attempted to regenerate his severed arm, he discovered that something about the girl's slash had an unusual property. It seemed to contain a magic-canceling effect, preventing him from utilizing his powers to mend the wound. For the first time in his 500 years of existence, Ace faced a dilemma he had never encountered before. Sweat trickled down Ace's brow, a physical manifestation of the intense battle and the unfamiliar emotions coursing through him—defeat and the looming specter of death. It was a sensation he had never experienced, and it only fueled his determination to emerge victorious. Realizing that traditional magic wouldn't work against this adversary, Ace made a resolute decision. He summoned his ultimate weapon, The Lost Sword. It was a blade that only he could wield, a testament to his immense power. With a deep breath, Ace channeled his dark energy into the sword, modifying it to also possess the ability to cancel magic. With The Lost Sword in hand, Ace stood proudly before the enigmatic girl. He couldn't help but acknowledge her formidable strength, a rare compliment from the Demon King himself. "You are truly exceptional to have overwhelmed me this far," he remarked. "But make no mistake; it will be I who emerges victorious in the end." The duel between Ace and the enigmatic girl escalated to epic proportions. Each time their swords clashed, the very realm itself seemed to quiver in response. The sheer force of their confrontation unleashed destruction upon the landscape, leaving a trail of chaos in their wake. The girl proved to be a formidable opponent, always one step ahead of Ace. Her skill with the blade was unparalleled, and their battle was a mesmerizing display of unmatched swordsmanship. With every strike, their swords collided with such force that shockwaves rippled through the demon realm. Cracks formed in the ground, and the skies above crackled with energy as the clash of titans continued. Ace wasn't one to rely solely on his swordsmanship. He summoned his powers, unleashing a devastating slash of Kuhaku Goku. The dark energy cut through the girl's legs, causing her to lose them. However, Ace was left speechless as she instantly regenerated them. His powers had proven ineffective against her.
In a moment of realization, Ace understood that her regeneration was not reliant on magic. It was a capability beyond conventional magical abilities. She possessed a resilience that transcended the boundaries of the arcane. The battle raged on, and Ace found himself locked in a fierce struggle against an opponent who continually defied his expectations. The enigmatic girl's uncanny abilities posed a formidable challenge, and the outcome of their duel remained uncertain. It was a clash of strength, skill, and resilience, and neither combatant was willing to yield. As Ace grappled with the realization that the enigmatic girl's regeneration was beyond conventional magic, she seized the opportunity to strike back with a devastating assault. In a fraction of a second, she unleashed a barrage of slashes that cut through Ace's defenses.
The onslaught was overwhelming. The girl's strikes were precise and merciless, leaving Ace with no time to react. Each slash left a trail of destruction, and Ace felt an excruciating pain radiating from countless wounds. The force of the assault was enough to make Ace spit out blood, a rare occurrence for a being as powerful as he. His once-unshakeable confidence was waning as he struggled to withstand the relentless barrage. Despite his immense strength and abilities, Ace found himself pushed to the brink by the enigmatic girl's incredible assault. The outcome of their battle had never been more uncertain, and the realization that he faced a foe who could match and even surpass his power left him in a perilous situation. The relentless battle between Ace and the enigmatic girl had reached new heights, with both combatants taking to the skies. However, the girl's overwhelming assault had taken its toll on the Demon King. In a final, devastating blow, the girl's strikes sent Ace hurtling towards the ground with tremendous force. He crashed into the earth with a thunderous impact, leaving a deep crater in his wake. Lying amidst the rubble and debris, Ace was unable to move. His body was battered and broken, and the pain coursing through him was excruciating. For the first time in centuries, he found himself incapacitated, his powers temporarily extinguished. The fallen king lay on the ground, vulnerable and defeated, as the enigmatic girl hovered above him. The outcome of their battle had taken an unexpected turn, and the realms awaited the resolution of this pivotal moment, uncertain of what the future held. With Ace lying vulnerable and defeated, the enigmatic girl descended from the sky and approached him with an air of finality. She raised her hand, and in a swift, ominous gesture, she made a movement that caused Ace's heart to explode within his chest. The sudden and brutal attack left Ace lifeless, his once-mighty heart reduced to a lifeless void. The Demon King had been defeated, and the realms now faced a new and uncertain future. As the girl gazed upon her fallen adversary. The battle had concluded with her as the victor, and her actions would undoubtedly have far-reaching consequences for the realms. The chapter came to a close with the grim realization that Ace Kurotsuchi, the indomitable Demon King, had met his end. The realms were forever changed, and the darkness that had plagued them would continue to loom, its true intentions and origins shrouded in mystery.
