Resonance of Shadows

As the cheers and murmurs began to fade, Aqua sheathed Darkness, returning the enigmatic blade into the depths of his subspace artifact. Its oppressive aura dissipated, but the weight of the clash lingered in the air. The faint scent of ozone and scorched marble hung heavily in the expansive arena, a testament to the intensity of the duel.

Aqua strode purposefully toward the sidelines, where Casial, Claire, and Emilia stood waiting, their expressions a blend of awe and anticipation. The soft afternoon sunlight streamed through the high-arched windows, casting golden patterns on the cracked floor beneath their feet. Venustusia, the revered Head of the academy, approached with measured grace, her piercing gaze fixed on Aqua.

"You know Blink. It's awesome," Casial blurted out, unable to contain his excitement. His eyes sparkled with pride as he looked at Aqua, his admiration evident.

Aqua tilted his head slightly, his calm demeanor unchanged. "What is Blink?" he asked, his tone genuinely curious.

Casial's animated response followed swiftly. "The magic you used at the end to defeat Regis—it's called Blink."

Aqua's expression remained unshaken as he explained, "Ah, teleportation magic. Yes. My brother created it and taught it to me. It's the only magic I know."

A profound silence fell over the group. The revelation seemed to ripple outward, leaving Claire, Casial, and even Venustusia visibly startled. Claire's delicate features were etched with disbelief. "You know that magic—even though you're a swordsman?" she asked, her voice tinged with amazement. "And you're saying Ray Rein recreated it?"

Aqua nodded with serene certainty, as though the notion was unremarkable. Yet, to the imperial siblings and their mother, it was anything but ordinary. Venustusia's composed exterior betrayed the faintest flicker of surprise. Blink magic was her own creation, an unparalleled technique thought to be exclusive to her genius. The idea that it had been replicated—and possibly refined—by Ray Rein was both astonishing and unsettling.

Before Venustusia could voice her thoughts, Claire interjected, her astonishment giving way to an eager inquiry. "And Darkness," she said, glancing at the subspace artifact on Aqua's coat, "that sword—it's unlike anything I've ever seen."

Casial chimed in with enthusiasm, "It's currently sealed. Even then, it's incredible." Aqua offered a subtle nod, affirming the statement without elaboration.

Venustusia's sharp gaze lingered on Aqua. Internally, her thoughts raced as she connected the dots. Was this the blade Ray Rein had wielded during the war against Count Froy? Rumors spoke of an artifact of overwhelming power, yet her sources had never described a sword. The mystery only deepened, but Venustusia chose to set it aside for the moment.

With her customary poise, she addressed Aqua. "Congratulations on your victory against the academy's best second-year student," she said, her tone warm yet measured. Her smile, however, did not reach her eyes as she glanced briefly at Regis, whose flushed face betrayed more than the exertion of battle. Venustusia knew of Regis's unspoken infatuation with Claire, a sentiment she did not condone in the countless admirers who approached her daughter.

Claire, unaware of her mother's thoughts, stepped closer to Aqua. Her sapphire eyes shone with an earnest light as she regarded him. Venustusia watched silently, her smile softening as she observed the twins and Aqua. Despite the swirling intrigue, her family's happiness remained her priority.

As the crowd dispersed, the arena grew quieter, the echoes of the duel fading into memory. Yet for those who had witnessed it, the resonance of shadows—the clash of determination, destiny, and an enigmatic blade—would linger for much longer.
