Kingdom Hearts: Consumed by Darkness

The Colosseum was electrified with anticipation as Sephiroth and Achilles stepped into the arena. The crowd was a cacophony of cheers and jeers, the noise rising in waves as the two legendary warriors faced each other. On one side stood Sephiroth, his silver hair cascading down his back, his piercing green eyes glowing with calm intensity. He held the Masamune loosely in one hand, its impossibly long blade reflecting the sunlight. Across from him, Achilles stood tall, his golden armor gleaming brilliantly. He was the epitome of divine power, his spear gripped tightly in one hand, his shield in the other.

Phil's voice boomed across the arena. "Ladies and gentlemen! This is the match you've all been waiting for—the finals of the Advanced Tournament! On one side, we have Sephiroth, the Second Coming of Hermes, known for his unmatched speed and devastating attacks. And on the other, Achilles, the Invincible Warrior, undefeated and unscathed in battle. Let's see if speed can triumph over divine invincibility!"

The gong sounded, and the battle began.

Sephiroth vanished the instant the match started, leaving nothing but a blur in his wake. Achilles pivoted smoothly, his keen eyes tracking the faintest movement. As Sephiroth reappeared behind him, the golden warrior spun on his heel, his spear lashing out like a thunderbolt. The Masamune rose in a flash, deflecting the blow with a metallic clang.

Achilles didn't pause. He pressed forward, his movements calculated and deliberate. Each strike of his spear was like the fall of a mountain, the sheer weight and precision of his attacks forcing Sephiroth to stay on the defensive. The crowd roared as the invincible warrior demonstrated why he had earned his title.

Sephiroth, however, was unfazed. He danced around Achilles' relentless assault, his speed and agility keeping him just out of reach. Each time Achilles aimed for a strike, Sephiroth was already gone, forcing the golden warrior to adjust his stance.

"You're fast," Achilles acknowledged, his voice carrying across the arena. "But speed means nothing if you can't harm me."

Sephiroth smirked, his voice calm and cutting. "And strength means nothing if you can't hit me."

Achilles slammed his spear into the ground, the impact sending a shockwave through the arena. Sephiroth leapt into the air to avoid it, but Achilles was already moving. He hurled his shield with incredible force, aiming for the space where Sephiroth would land. Sephiroth twisted mid-air, the Masamune cutting through the air to deflect the shield. The collision sent sparks flying, and Sephiroth landed gracefully, his feet barely touching the ground before he vanished again.

The Masamune lashed out in a series of lightning-fast strikes, each one aimed at the gaps in Achilles' armor. Sparks flew as the blade glanced off the golden surface, leaving not a scratch behind. Achilles countered with wide, sweeping arcs of his spear, forcing Sephiroth to adjust his movements constantly.

Sephiroth's speed was his greatest weapon, but Achilles was no fool. He began targeting not Sephiroth directly but the areas around him, striking where Sephiroth stood moments before and cutting off potential escape routes. Each strike created shockwaves, forcing Sephiroth to stay on the move.

The crowd was enthralled, the arena alive with cheers and gasps as the two warriors tested each other's limits.

Sephiroth stepped back, his expression growing darker. "Impressive," he admitted. "But let's see how you handle this."

He raised his free hand, and the air around him began to shimmer with heat. Suddenly, massive pillars of fire erupted around Achilles, the Firaga Wall trapping the golden warrior in a cage of flames. The heat was intense, and the flames sucked in debris from the arena floor, creating a swirling inferno.

Achilles didn't flinch. He slammed his spear into the ground, creating a powerful shockwave that extinguished the flames in an instant. The golden warrior emerged unscathed, his armor glowing faintly from the heat.

Sephiroth's smirk widened. He raised his hand again, and orbs of darkness filled with dark flames—the infamous Shadow Flares—materialized around Achilles. The orbs homed in on the golden warrior, exploding one by one as they struck his shield and armor. Achilles moved with precision, deflecting the orbs and closing the distance between them.

Sephiroth vanished again, reappearing above Achilles with his blade poised to strike. Achilles raised his shield, the Masamune crashing against it with a deafening clang. The force of the blow sent tremors through the ground, but Achilles held firm, his shield unyielding.

"You'll have to do better than that," Achilles taunted, his voice steady despite the onslaught.

Sephiroth's smirk faded, replaced by a cold, calculating expression. Dark energy began to swirl around him, his aura growing oppressive. He raised his hand to the sky, and meteors began to descend, exploding on impact and shrouding the arena in smoke and debris.

The crowd was on the edge of their seats, the tension in the air almost unbearable. As the dust settled, Achilles stood tall, his golden armor shining despite the destruction around him. He raised his spear, pointing it at Sephiroth. "You can't win. Your tricks mean nothing against me."

Sephiroth's eyes narrowed, and his aura darkened further. He raised his blade high, dark energy coalescing around it. When he struck the ground, the energy erupted in a massive shockwave, forcing Achilles to brace himself. The golden warrior lunged forward, his spear aimed directly at Sephiroth's chest.

Sephiroth sidestepped the attack with ease, his movements a blur. He began circling Achilles, his blade lashing out in a relentless series of strikes. Each blow was aimed with surgical precision, targeting the few gaps in Achilles' armor. While none of the attacks pierced his invincible skin, the relentless assault began to disrupt Achilles' rhythm.

The turning point came when Sephiroth unleashed his most devastating technique. He raised his hand, his aura pulsing with malice. "Heartless Angel," he intoned, his voice cold and unforgiving.

A wave of energy spread from Sephiroth, sapping Achilles' strength and magic. The golden warrior staggered for the first time, his invincibility faltering as the effects of the attack took hold. Sephiroth followed up with "Flash," a series of sixteen lightning-fast Iaido slashes that struck with deadly precision.

Achilles stumbled, his movements slowing as he struggled to regain his footing. Sephiroth took advantage of the opening, unleashing a variation of Cloud's Omnislash. He flew around the arena, his blade striking from every angle in a dazzling display of speed and power.

Finally, with one last powerful strike, Sephiroth sent Achilles tumbling out of the arena. The crowd fell silent, the shock of seeing their undefeated champion defeated rendering them speechless.

Phil's voice broke the silence. "And the winner of the Advance Tournament is… Sephiroth, the Second Coming of Hermes!"

Sephiroth turned and walked away from the arena, his expression unreadable. As he exited, his eyes briefly met Helios's in the stands, a silent message passing between them.

Helios sighed and stood, disappearing into the shadows.
