As the Hotetsu organization members emerged from the portal, Ace quickly glanced at Yua, noting her apprehension. He took a moment to explain, both to her and the reader, how ranks in the Demon Realm worked. "Yua, in the Demon Realm, there are seven Captains, besides me, The Demon King" Ace began, his tone focused but informative. "We're among the highest-ranking demons, each with unique abilities and responsibilities. Kyokuske Yoratami, whom we met earlier, is one of them." Yua nodded, her curiosity piqued. "So, what comes after the Captains?" Ace continued, "Below the Captains, there are various ranks, such as Generals, Lieutenants, and soldiers. Each rank has its own duties and powers. The ranking system helps maintain order and ensures that the Demon Realm operates smoothly." As the Hotetsu organization members encircled Ace and Yua, Ace's confidence didn't waver. He began to explain the intricacies of the Demon Realm's hierarchy to Yua while effortlessly defeating each of their adversaries with just one hand, never going all-out in his attacks. "Yua," Ace started, his voice calm amid the chaos, "the Demon Realm's hierarchy is built upon a balance of power and responsibility. The Captains are chosen not just for their strength but also their wisdom and leadership qualities." With a swift, controlled motion, Ace hollowed one of the attackers, rendering them immobile. "This is where our training and experience come into play," he continued, "we learn to harness our powers with precision." Ace's words were punctuated by his actions as he effortlessly subdued another opponent, their powers proving no match for his mastery. "We aim to resolve conflicts without causing unnecessary harm," he said, demonstrating the delicate balance between strength and restraint. But of course I will kill them all. With each passing moment, Ace maintained a conversation with Yua, explaining the complexities of the Demon Realm's hierarchy while gracefully dispatching their adversaries. His movements were almost like a dance, a testament to his control over his immense power. "We'll have to ensure the safety of both worlds, Yua," Ace said, his voice unwavering as he cam to the last one of their foes. "But we'll do it with care and precision, protecting what matters most without unnecessary destruction." Ace puts his hand in a horizontal position and says "Shin'en no Hakka" and he waves his hand like a sword slowly and a black trail behind his hand appears, then it quickly launches toward the last enemy and when it impacted all the trees and earth behind him, blew up. When the fight was over the only thing left was the enemies blood all over the place. They went on a walk towards an ancient forgotten temple because Ace felt so much power inside it and needed to check it out. As the sun dipped below the crimson horizon of the Demon Realm, Ace and Yua found themselves in a dimly lit chamber within the depths of an ancient, forgotten temple. In the center of the room, bathed in an eerie azure glow, rested the source of their quest: the enigmatic rune. Ace's keen eyes studied the rune, his mind racing with possibilities. "Yua, this rune holds the key to untold power, but it comes at a great cost to others. We must find a way to neutralize it," he said, his voice tinged with determination. Yua nodded, her eyes fixed on the rune's pulsating energy. "But how do we even begin, Ace? It's said that this rune has confounded the brightest minds of the Demon Realm for centuries." Ace wore a confident grin as he approached the rune. "That's precisely why we're the ones to solve this mystery. You see, Yua, every powerful artifact has a weakness, a vulnerability that can be exploited. We just need to find it." He carefully extended his hand toward the rune, his fingers hovering inches away from its surface. "It's absorbing energy from anyone who touches it, but it can't be limitless. There must be a limit to its capacity." Yua watched in awe as Ace's hand approached the rune. It was as if his intellect alone was enough to disarm the malevolent artifact. "What's your plan, Ace?" A mischievous glint sparkled in Ace's eyes. "I believe we can overload the rune. If it can't contain any more power, it should release everything it has stolen." With that, Ace's fingers made contact with the rune. A surge of energy coursed through him, but Ace's unwavering determination held firm. Beads of sweat formed on his brow as he concentrated, pushing the amulet to its limits. Yua witnessed the rune's glow intensify until it reached a blinding crescendo. A deafening roar filled the chamber as the rune shattered into a thousand shards, each releasing a torrent of stolen power. As the dust settled and the chamber fell silent, Ace turned to Yua with a triumphant smile. "Mystery solved, Yua. The amulet's reign of power has come to an end."
