I will refine the English translation by moderating the prose intensity, sharpening the character dialogue, and smoothing the transitions between metaphors to ensure a more natural narrative flow.
The moment I stepped into the summit plaza, I felt as if the world’s gravity had fundamentally shifted.
An oppressive, inescapable weight settled over us. The air felt thick, as if the oxygen had been replaced by invisible particles of lead. Merely standing and breathing was a struggle; it felt as if my very life force was being ruthlessly stripped from my lungs. The rift we had opened in the barrier yesterday was gone. In its place, a pillar of crimson light surged toward the heavens, glowing with a sinister brilliance that threatened to sear my retinas.
The ground was strangely damp. The scent of earth, parched by the ritual’s unnatural heat, mingled with the metallic tang of blood wafting from an unseen source. Together, they formed a stagnant, sickening aroma that numbed the senses.
"So, the mice have returned. Still too foolish to recognize their own impotence."
A man stood before the central altar where the Moon God was held captive. Like the other pawns of the Observers, he wore a featureless white mask, but his garments were of a far higher quality. He wore a kariginu—a hunting robe—of deepest black, woven from a fabric that seemed to swallow the light. He was the captain presiding over this blasphemous rite.
Distorted lunar crests were embroidered onto his billowing sleeves with the precision of a curse, their patterns enough to unbalance any who looked too closely. From the shadows of his mask, a clinical, freezing gaze shot out like an icy blade, piercing Koyoi’s chest with terrifying accuracy.
"Intruders confirmed. This time, see that they are eradicated."
With a ritualistic flourish, the man leveled his staff. At the signal, the silent ground began to churn. Humanoid figures rose from the earth like black mud bubbling to the surface. Ten, twenty...
Every one of them wore the same white mask and brandished weapons that glinted with a dull, inorganic light. The masks were smooth porcelain, devoid of eyes or mouths, yet they radiated a raw, pathological will to "observe." In their gnarled hands, they gripped short spears and warped, sickle-like blades. Traced by the scorched crimson light of the atmosphere, these weapons emitted a cold, absolute lethality—as if a single touch would freeze the blood in one's veins.
"Hmph! Better numbers than yesterday, at least," Asahi shouted, unsheathing the heavy sword from his back with a force that seemed to shake the earth. "I'll handle this lot! I’m used to clearing the way. You guys stop that damn ritual—now!"
Asahi lunged into the enemy formation like a bullet. Heavy arcs of steel carved through the air as he swung his blade. He parried the rain of spears with minimal movement, kicking through mud-like bodies and armored shells to force a path through the chaos. Gravel flew beneath his feet, and with every ferocious strike, the stagnant red particles in the air scattered like sparks.
Even as they were hacked apart, the masked men uttered no human cries. Only the dull, unpleasant sound of dry earth crumbling echoed across the plaza. Asahi’s breathing grew ragged and his lungs burned, but his iron footwork never wavered. Every time his sword fell, the warped shadows of the masked men dissolved back into the void.
"Go, Koyoi! Keep moving—I’ve got your back!"
Kuon sprinted toward the altar, weaving through the gaps in the fighting. Koyoi forced her legs to move, desperately keeping pace behind him.
"I gave orders that no one be allowed to escape," the man in the black kariginu said, snapping his fingers with robotic indifference. "Not a single mouse leaves this barrier."
From the base of the altar, countless chains of crimson light snaked out, moving with a predatory, living will. The chains liquified the stone as they crawled, relentlessly homing in on Koyoi’s feet. Even from the narrowest cracks in the rock, those deathly hands reached out to seal her escape.
"Ah—!"
Koyoi stumbled, unable to dodge in time. A searing chain coiled mercilessly around her ankle. A white-hot agony, far beyond a mere burn, surged through her entire body as if the light were charring her very soul.
"Lord of the Wind! Help me!" she screamed.
『Leave it to me! I’ll blow these filthy chains away!』
The Wind God’s furious voice resonated from her pouch. A localized gale erupted around Koyoi, effortlessly snapping the red chains as if they were scrap paper.
"How tiresome... To think a vessel capable of wielding divine power still remained in this land."
The man let out a low, cold murmur and leveled his staff. A massive fireball swelled at the tip, vacuuming in the surrounding heat. It distorted the moonlight as it expanded, radiating a piercing, lethal temperature. The tips of Koyoi’s hair shriveled; the smell of singed eyebrows stung her nose.
Even so, she did not look away. She knew that if she flinched now, they would never reach the Moon God.
"Stolen power is just a cheap imitation," Kuon said, stepping forward to shield her. His fingers moved with lightning speed over the Star-Reading Disk, operating it as if to unravel a knot. "Your control is pathetic. This is the end for those who drown in their own equations."
A needle-thin beam of blue light shot from the disk, striking the fireball at its weakest point. A massive explosion shook the summit. The blast brushed hotly against Koyoi’s cheek, the scent of scorched air lingering in her nose. As the smoke cleared, Kuon stood his ground with a defiant smirk.
Though sweat trailed down his face, he did not avert his eyes. His glass-like left eye shone with a clinical rage, cold enough to burn away the past.
"My eye perceives the flow of divine energy itself. Your clumsy techniques are laid bare before me."
"...You. The runaway from that time." For the first time, a hint of human emotion—a shock as cold as ice—crept into the man's voice. "To think a failed specimen marked for disposal survived like a sewer rat. A significant error in my calculations."
"Yeah. And I'm here to drag monsters like you back to hell where you belong."
Kuon and the captain faced off, sparks flying from their locked gazes. Seizing that breathless opening, Koyoi sprinted toward the altar with everything she had. Behind her, Kuon’s voice dropped to a heavy, quiet growl.
"You erased my name in the name of your 'experiments.' Now, I’m going to erase you from the memory of this world."
The man’s fingers froze for a fraction of a second. Before Koyoi, the massive pillar of red light loomed, its radiant heat scorching her skin. The terror of being blasted back yesterday returned in a vivid flash, but she did not stop. At the center of the crimson death, the Moon God flickered, a light ready to fade forever.
"Wait for me! I'm getting you out!"
Koyoi held the Glass Eye high. Vidro. Her hidden power was finally being tested with the fate of the world on the line.
『Reflecting. I shall reflect all the distortions of the world within this eye.』
Vidro’s voice—transparent and sorrowful—vibrated through the air.
『Gathering, and returning. This false light... I shall hurl it back to its source. Koyoi, do not let go of my hand.』
The Glass Eye began to suck in the tyrannical red light at a maddening speed. The energy condensed into a single, sharp point within the sphere. The glass trembled violently, sending a searing heat through Koyoi’s arm that threatened to unravel her resolve. The Wind God wrapped around her, scattering the heat with a fading breeze, while the voice of the Moon God echoed quietly in her soul, supporting her from within.
A red vortex pulsed inside the glass, condensing smaller and sharper. Koyoi’s arm went numb and her knees shook, but she never let go. If she failed here, the Moon God would sink into eternal darkness.
"GO!"
Koyoi let out a scream that felt like it was carving away her very being. The light stored within Vidro was released all at once toward the apex—the weakest point of the barrier. In that moment, the summit was enveloped in a silence as deep as the ocean floor. The only reality left was the hammering of her heart and the presence of the gods beside her.
A prayer for the Moon God, a fire-like rage toward the Observers, and a primal fear of death—all of it drew a single, pure path of light. The path was as straight as a ruler, yet it wavered, reflecting Koyoi's inner turmoil.
Her arm trembled beyond its limits, sweat dripping onto the stone. Through her soul, she felt the Moon God take a faint, certain breath. Behind her, the sound of Asahi's sword clashing with the masked men rang out, punctuated by the thuds of their collapsing bodies. The gears of Kuon's Star-Reading Disk shrieked as his blue light overlapped with Koyoi's, a supporting geometric pattern for her strike.
The wills of the three and the power of the gods aligned without a second's deviation, creating a miraculous equilibrium. Koyoi forced down the scream swirling inside her and closed her eyes. The light in her chest grew hotter than ever before; the breath of the Wind God and the heartbeat of the Glass God melted together. She felt the sensation of silver tears, dripping from the celestial abyss, brushing against her cheek.
She vowed to answer that droplet with her life. The surface of the red barrier shrieked in rejection, the atmosphere groaning with the friction. Within that savage vibration, Koyoi found it—the gentle pulse of the Moon God's soul. The moment she touched it, the flame in her chest erupted, sweeping away the darkness.
Behind her, Asahi's breathing grew labored, but he did not break. Though the masked men were thinning, their pressure was increasing as they rushed to complete the ritual. The captain struck his staff like a curse, and chains of red light snaked out from inside the barrier like serpents, intent on binding the Moon God even more cruelly.
"Hurry, Koyoi! They’re hitting the critical point!" Asahi's voice was a raw shout.
Kuon layered more blue light, focusing the radiance in Koyoi's hands with needle-like precision. The red vortex inside the Glass Eye let out a ferocious roar as it contracted to its limit, transforming into a single flash of silver lightning. Koyoi squeezed out the last drop of her strength and entrusted her entire destiny to that path of light.
At the edge of her vision, the Moon God's light flickered with a terminal intensity—a life-or-death signal that this was the seam of the world. Koyoi inhaled until her lungs felt like they would tear, burning the light in her chest like a sun. She would stake tomorrow on this one strike.
Outside the barrier, the wind swirled. The Wind God poured divine energy into her back, pushing her toward the future. The vortex converged into a single spear. Koyoi fully extended her trembling arm.
The barrier undulated; the air distorted. The silver light blinked. I will make it reach.
Time stretched like honey. The next instant would decide everything. Koyoi closed her eyes, called out the name she had almost lost, and cut away all hesitation.
The spear of light pierced the seam.
The world held its breath. Light shattered the heavens. And then, silence.
The violent roar of the summit faded. In the sudden quiet, a memory of the town lights on the distant moon-viewing hill flickered through my mind like a passing dream. As the world finally went still, the tension slowly, surely, drained from my shoulders.
