Usagi's twin blades swung fiercely, shattering the black and crimson flames into fragments. In her hands, the fiery shards reassembled, flickering and converging into two virtual laser pistols. Streams of searing energy swirled at their muzzles, ready to be unleashed.
"Take this—Usagi Cannon Barrage!"
With a thunderous roar, Usagi unleashed an unrelenting torrent of blazing beams from the pistols. The searing lightstorm ripped through the air, tearing toward Akari's position like a meteor shower.
Akari moved like a ghost, weaving through the ruins with uncanny speed. But Usagi's onslaught gave him no reprieve. The deafening explosions shook the ground as the fiery blasts illuminated the night sky. Buildings collapsed under the destructive power, their skeletal frames crumbling amidst the inferno, while the rubble seemed to ignite in the crimson glow.
Akari leapt upward, bounding off the scattered debris, his speed accelerating with each rebound. His movements blurred into a streak of shadow, darting through the chaos. Usagi's sharp gaze locked onto him, recalibrating her attacks to match his every move. Her laser pistols precisely dismantled every trap he had set—bullets, daggers, and steel wires disintegrated in the fiery storm.
"Running out of tricks?" Usagi sneered, her voice cutting through the din. She had discerned Akari's strategy—his arsenal was depleting rapidly, and his every motion betrayed his intent to close the distance.
"You've got nowhere left to hide."
Her barrage intensified, the cannon-like beams obliterating Akari's cover. His only choice was to continue his rapid approach. Yet, this was precisely the moment Usagi had been waiting for.
With a swift crossing of her arms, the black and crimson pistols shattered into fragments, spiraling in midair. The luminous shards fused together, forging a massive, awe-inspiring weapon. Energy pulsated as the weapon's form took shape, the very air around it warping under immense pressure.
The weapon emerged—a colossal energy cannon, its surface radiating with an ominous blend of black metal and crimson flames. Electric currents flickered across its body, pulsating with boundless energy. The cannon's barrel was vast, radiating an oppressive heat that distorted the surrounding air. It was a harbinger of destruction, its sheer presence dwarfing everything around it.
Usagi stood resolutely, her silhouette framed by the lunar glow, exuding an air of cold authority. The colossal cannon in her hands crackled with barely contained energy, its core glowing with an intensity that seemed to drain the light from the stars. The ruins quaked under its weight, as though the earth itself recognized its impending doom.
Suspended mid-air, Akari realized too late that he had no foothold left. Usagi's piercing gaze locked onto him, her precision unerring. With a swift motion, she raised the massive weapon, its glowing barrel aimed directly at her target.
The world seemed to freeze as Usagi's voice rang out, resolute and thunderous:
"Doomsday Usagi Cannon—Fire!"
A blinding torrent of light erupted from the cannon, tearing through the battlefield like divine retribution. The beam carved through the ruins, a river of incinerating energy that consumed everything in its path. The air itself seemed to scream under the sheer force of the blast, as the ground beneath it erupted into molten slag.
The explosion's roar was apocalyptic, reverberating like the final toll of the world's end. The beam surged forward with unstoppable momentum, obliterating buildings, steel, and stone alike. The night sky split apart, the darkness consumed by an overwhelming brilliance. Shattered debris and burning fragments flew in all directions, engulfed by the unrelenting tide of destruction.
Waves of energy rippled outward, expanding like the birth of a star. Usagi held the cannon steady, her icy determination unyielding. The ground quaked violently as the torrent continued, leaving no room for survival. Akari's figure vanished within the inferno, his silhouette lost to the cataclysmic flood. Hayato, too, was engulfed, his crazed smirk erased in an instant.
As the earth quivered and the sky trembled, the city crumbled into ashes. The once-quiet night transformed into an endless sea of fire. Usagi's assault ceased only when the cannon's energy was fully spent. Silence fell, broken only by the crackle of residual flames and the distant collapse of weakened structures.
The battlefield lay in ruins, the land scorched beyond recognition. Usagi lowered the colossal cannon, its form dissipating into fading embers. Her cold, unwavering gaze surveyed the devastation. In her hands, she held the power of absolute destruction—victory forged in fire and wrath.
Against the divided will of Akari, this was not just her triumph, but the dawn of annihilation. The battle had ended, but the scars it left would linger eternally.
