Ace stood alone in the shadowy depths of the demon realm, his eyes concealed beneath his unruly hair. His face was etched with frustration, anger, and profound sadness. He had been away for too long, and it weighed heavily on his soul. As he contemplated the darkness that continued to spread, he couldn't suppress the overwhelming emotions that surged within him. It was not just a battle against the enigmatic girl and the malevolent darkness; it was a war waged against the torment of his own heart. His eyes remained hidden as he transported himself in an instant to where the captains, Zara, and Yua's lifeless body lay. The entire demon realm shuddered as Ace's menacing aura enveloped the area. It was a presence that made it hard for anyone to breathe, a force that resonated with unbridled power. With a flash of his thoughts, Ace's sword was summoned, a nameless yet fearsome weapon that had become an extension of his will. The magic-infused slash, known as Shin'en no Hakka, surged to life with an otherworldly energy. In a single, powerful slash, the attack cleaved through the malevolent Amulet, dividing it into two halves. A shockwave of energy radiated outward, obliterating everything in its path. The malevolent darkness that had plagued the demon realm was no more, reduced to nothing but ashes. The realm began to regain its balance, and a sense of relief washed over all who bore witness to Ace's power. Ace's eyes remained hidden beneath his hair as he turned his attention to Yua's lifeless body. He knelt beside her, and the weight of sorrow and guilt pressed upon him. "Yua," he whispered, his voice heavy with emotion. "I'm so sorry I wasn't here to protect you." He reached out to touch her lifeless hand, and for a fleeting moment, it seemed as though there was a connection, a link between them that transcended the boundary between life and death. Ace's heart ached with the depth of his loss, and he vowed to honor Yua's memory by continuing to fight against the malevolent darkness. Her sacrifice would not be in vain. In the aftermath of this emotional and powerful moment, Ace remained a formidable presence, a guardian of the realms, and a beacon of hope. His newfound strength, his understanding of magic, and the guidance of Rokko Shisen had transformed him into a formidable force. With his menacing aura and his unwavering determination, he was more determined than ever to confront the enigmatic girl and uncover the mysteries that still shrouded their existence. In the aftermath of the monumental clash, Ace had obliterated the malevolent Amulet and shattered its barrier, unleashing an astonishing power that cut through the very fabric of space and time. His slash, Shin'en no Hakka, was an awe-inspiring force that transcended dimensions. It was as if he had cut through the very essence of reality itself—a power that defied understanding. Ace's newfound strength was staggering. It was not reliant on external artifacts or amulets; it was a manifestation of his sheer willpower and determination. The dark energy within him, guided by the Left Eye of God, Rokko Shisen, had propelled him to new heights. It allowed him to cut through the barrier and the Amulet without the need for Yua's necklace. His power was now unmatched.
But while Ace had grown stronger, he wasn't the only one who had experienced a transformation. In a realm shrouded in darkness, the Enigmatic Girl's eyes suddenly turned a deep crimson red, like two burning coals. Her once-prominent horns had disappeared, leaving a stark change in her appearance. She was no longer the same person. Her emotions had given way to a cold, unfeeling determination. She had become a ruthless killing machine, devoid of any humanity. In this moment, Ace's power was unmatched, but his enemy's transformation made her all the more formidable. Ace swiftly departed from the scene, leaving no trace for Zara and the captains to notice his departure. His speed had reached unparalleled heights, allowing him to move through the demon realm with astonishing swiftness. The Enigmatic Girl, now transformed and known as Ruta, the Queen of Chaos, waited patiently. Her eyes were filled with a strange mix of joy and anticipation. It was as if a switch had been flipped within her, and she was ready for a new kind of battle. When Ace finally reappeared before her, he remained an enigmatic figure, showing no emotion and concealing his eyes. Ruta's eyes lit up with delight. "Ace," she spoke, her voice clear and tinged with excitement. "That was a thrilling battle we had. I had so much fun. This time, I'll have even more fun. Are you ready to go all out?" Ace's response was as stoic as ever, his resolve unwavering. With a swift motion, he transported them both to a different dimension, far removed from the realms they had known. It was a place where they could unleash their full power without causing further destruction. As they stood in this newfound dimension, Ruta's crimson eyes sparkled with anticipation. She had transcended her previous limitations and was eager for a battle that would test the very limits of their abilities. Ace, now fully prepared to face this formidable adversary, would confront not just Ruta but also the mysteries of their existence. The battle ahead was destined to be unlike any other, a clash of titanic forces that would shape the fate of the realms themselves.
