Kaga raised her head, sneering as she observed the tense atmosphere between Shingin and Watcher 16. In a soft voice, she remarked, "They say souls that resonate with one another naturally create bonds of love. The stronger Shingin's alien soul becomes, the more resonant Watcher 16's alien soul will grow. Isn't this the scenario we've been waiting for?"
Watcher 16's lips curled into an amused smirk at her words. He fixed a cold gaze on Shingin, his eyes glinting with a hint of provocation. "Well? In your current state, how much strength can you muster? Show me."
Shingin gave no response. His gaze was as cold as the depths of the abyss, devoid of anger or emotion, staring at Watcher 16 as though he were looking at a meaningless, lifeless being.
"Hmph," Watcher 16 sneered, stepping closer. "Don't look at me like that. I'm not one of those insignificant pawns you can ignore…"
Before he could finish, Shingin's answer came not in words, but in action. Slowly, he raised his hand and spoke two low, chilling syllables: "Raigeki."
At the sound of his voice, Shingen's corpse began to float, its frozen form wrapped in an aura of purple and gold. From within the lifeless body emerged a spectral blue and red soul, flickering like a phantom as it flowed into Shingin's outstretched palm.
The soul took shape in his hand, transforming into a sword—a weapon exuding a menacing aura of death and slaughter. Its blade seemed forged from the flames of the soul itself, with blue and red fire intertwining and rippling along its edge like a living stream. The sword's brilliance was not dazzling but chilling, its blade emanating a sinister light that pierced deep into the hearts of those who looked upon it. At the end of the hilt, a blood-red rune shimmered faintly, as though watching all of existence with a malevolent gaze.
The weapon's oppressive aura weighed down the air, distorting the space around it. Anyone who approached could feel an invisible force clawing at their soul, an overwhelming presence that suffocated all who dared to draw near.
Shingin regarded the blade in his hand, a flicker of complex emotion passing through his eyes. His fingers traced the edge of the blade, and the soul flames burned brighter, emitting a deep, resonant hum.
The sword seemed to respond to his touch. The blue and red flames roared to life, letting out a sound like the exultant cry of a vengeful spirit. The air trembled violently as Shingin gripped the hilt, his aura of slaughter spreading outward like the herald of an imminent bloodbath.
Watcher 16's expression shifted subtly. First, he glanced at Shingen's corpse, then at the weapon in Shingin's hand, disbelief flickering in his eyes. His voice wavered as he spoke, "You… used your brother's soul… to forge a weapon?"
Shingin remained silent, his gaze locked onto Watcher 16, the soul-forged sword radiating boundless killing intent as he raised it, its tip aimed directly at his opponent.
The icy, unfeeling stare instantly froze the mocking expression on Watcher 16's face. A shiver ran from the soles of his feet to the top of his head—a bone-deep terror he couldn't suppress.
Kaga, standing off to the side, smiled slyly as she watched the scene unfold. In a low, chilling voice, she murmured, "Heh, Rayl… Was your brother's love for you greater than his ruthlessness, or was it the other way around?"
Nearby, Riyugi's heart trembled violently. She whispered to herself, "Rayl is dead…? Rayl was Shingin's brother?"
Watcher 16 pushed down his fear, forcing a cold smile as if willing himself into composure. "Whatever strength you have, I can match it."
Before his words had fully settled, an immense wave of water-based energy surged from his body. Crystal-clear streams swirled around him, exuding a sharp and biting coldness. With a swift motion of his hand, the streams transformed into countless deadly blades of water, slicing through the air like a storm of liquid light toward Shingin.
Shingin's expression didn't waver. He raised the Raigeki Sword with an almost casual motion. As its blade swept through the air, the oncoming torrents of water were abruptly severed, their halves freezing midair before shattering into a cascade of glittering ice fragments.
In that instant, a piercing sonic boom echoed from afar. Shingin's sword energy shot skyward, its terrifying power carving a thin, precise fissure through a distant mountain range. The smooth, glassy edges of the split terrain stood as a testament to the weapon's overwhelming might.
Watcher 16 narrowed his eyes, his once-calm demeanor now infused with wariness. Tightening his grip on his weapon, he steadied his stance, his predator-like gaze locked on Shingin. His fighting spirit burned even brighter, tinged with danger.
"Interesting…" Watcher 16 muttered under his breath. He began to move, his blade tracing elegant arcs in the air. The fluidity of his movements belied their lethal intent, the water that trailed his weapon writhing like a serpentine dragon, leaving shimmering streaks of light in its wake.
Shingin didn't hesitate. He extended his hands, summoning six ethereal, mirror-like barriers. They floated around him, gleaming with a mysterious aura that hinted at both defense and offense. Each icy mirror radiated an unearthly power that seemed to draw all who beheld it into a trance.
"Sixfold Ice Mirrors."
Without delay, Shingin launched himself at Watcher 16, his speed surpassing the limits of perception. The Raigeki Sword, wreathed in violet and gold energy, cleaved through space itself with an aura of annihilation. Watcher 16 met him head-on, his weapon parrying the strikes as the icy mirrors hummed with every clash, amplifying the shockwaves that rippled through the battlefield.
The metallic clang of blades colliding echoed endlessly as the two combatants exchanged blow after devastating blow. Shards of ice and bursts of water exploded around them, saturating the air with a bitter chill and an oppressive bloodlust.
Watcher 16 retreated a step, his breath slightly ragged, but Shingin refused to let up. Planting his foot firmly on the ground, he unleashed a gale of wind, his voice resonating with quiet authority: "Heaven's Vortex."
The air surged violently, forming a massive whirlwind infused with water and the soul-forged energy of the Raigeki Sword. Purple and gold light enveloped the weapon, its radiance intensifying as it slashed forward with an apocalyptic force.
The collision between their powers detonated like a cataclysmic eruption. The resulting shockwave reduced the surrounding terrain to rubble and left the entire battlefield cloaked in a suffocating mist of destruction. As the dust settled, Kaga's sinister smile widened.
"Shingin…" she murmured, her voice tinged with malicious delight. "You never cease to exceed expectations…"
