The darkness of the Demon World engulfed them as soon as Dante and Hadrian stepped through the portal. The air was thick and oppressive, saturated with a malicious energy that gnawed at their senses. The landscape was a twisted, nightmarish realm; jagged, obsidian rocks jutted out from the ground, and rivers of glowing red magma flowed through deep crevices, casting an eerie crimson light across the wasteland.
The ground beneath them pulsated as though alive, and the sky overhead was an endless void, churning with dark clouds that occasionally flashed with streaks of blood-red lightning. Strange, distorted forms loomed in the shadows, watching them with hungry, unblinking eyes.
Dante took a deep breath, a devilish grin spreading across his face as he surveyed the landscape. "Ah, home sweet home," he muttered with a smirk, cracking his knuckles. "Let's make sure we leave a mark here."
Hadrian chuckled despite the unease settling in his gut. "If we're doing this, we're doing it with style." He adjusted Kanshou and Bakuya at his sides, feeling the familiar hum of energy radiating from the twin blades. In his mind, he felt the reassuring presence of Hedwig and Oryou, his familiars, ready to support him in whatever lay ahead.
They moved forward, their footsteps echoing ominously in the unnatural silence of the realm. The path ahead twisted and shifted as if the Demon World itself was alive and determined to lead them astray. After walking through a dense fog of shadows, they finally reached an open expanse, where the ground gave way to a massive, grotesque structure towering over them—a twisted throne of bone and flesh.
And there, seated atop the throne, was Argosax the Chaos.
The demon lord's form was a horrific amalgamation of countless demon parts, his body a monstrous fusion of limbs, wings, and heads. Eyes of varying sizes dotted his flesh, each one shifting and blinking independently, staring at them with malevolent intent. His body oozed a dark, putrid liquid that sizzled and hissed as it dripped onto the ground, corroding the stone beneath him.
As they approached, Argosax stirred, his many heads turning in unison to face them. A deep, rumbling voice echoed from within his twisted form, each word laced with venom and madness.
"So... the sons of Sparda have come," he sneered, his voice reverberating through the air like thunder. "I remember your ancestor... the traitor who sealed me here. And now you dare to stand before me, thinking you can finish what he started?"
Dante grinned, his hand resting on Rebellion's hilt. "Finish it? Buddy, we're here to do more than that. We're here to wipe you off the map."
Hadrian stepped forward, his eyes blazing with determination. "Sparda may have locked you away, but we're here to make sure you stay down for good. Consider this the final chapter."
The demon lord let out a hideous laugh, his many heads writhing as he unleashed a torrent of dark energy that crackled around him like a storm. "Foolish mortals. Your strength is nothing compared to mine. I am beyond time, beyond death!"
Without another word, Argosax rose from his throne, his form shifting and warping as he prepared for battle. His massive wings unfurled, casting a shadow over the entire area, and the ground trembled as he stepped forward, his demonic power twisting the very fabric of reality around him.
Dante unsheathed Rebellion, his Devil Trigger form flickering as he channeled his demonic energy, his entire body surging with a crimson aura. "Hadrian, we take him down together. Watch for his wings—they're the source of most of his power!"
Hadrian nodded, summoning Kanshou and Bakuya into his hands. He could feel the weight of his family legacy on his shoulders, but it only fueled his determination. With a flick of his wrist, Kanshou and Bakuya glowed, the blades ready to strike.
Argosax began by raising one of his grotesque limbs, which morphed into a whip-like appendage. It lashed out with blinding speed, slicing through the air toward Hadrian. He leaped out of the way, rolling to avoid the strike as the ground where he had just been standing exploded in a shower of rock and molten lava.
"Close one!" he muttered, quickly regaining his stance.
From above, Argosax launched a barrage of light needles, raining down on them like a storm of deadly stars. Dante deflected the needles with his sword, moving swiftly to cover Hadrian as he dodged and countered.
"You're gonna have to do better than that, ugly!" Dante taunted, firing Ebony and Ivory in rapid succession, the bullets striking Argosax's many eyes and forcing him to recoil in pain.
Hadrian seized the opening, charging forward with Kanshou and Bakuya. With a fierce battle cry, he unleashed a flurry of strikes, his blades cutting through Argosax's grotesque flesh. The demon let out an enraged roar, his form twisting and shifting as he retaliated with a powerful blast of electricity.
"Hadrian, watch out!" Dante yelled, leaping in to intercept the attack. He took the brunt of the shock, his Devil Trigger form absorbing most of the impact, though sparks of electricity crackled along his body.
"Thanks," Hadrian breathed, giving Dante a grateful nod.
"Don't mention it. Just make sure you pay me back by taking this freak down," Dante replied with a grin.
Argosax unleashed his reality-warping powers, distorting space around them, making the ground shift and twist beneath their feet. Hadrian stumbled for a moment, but Hedwig and Oryou quickly responded. Hedwig created a protective barrier that stabilized the ground under him, while Oryou, in her snake-like tattoo form, slithered down Hadrian's arm and fired beams of energy that disrupted Argosax's dark magic.
"Persistent little pests!" Argosax roared, his eyes narrowing in fury. He morphed his hands into massive, blade-like appendages, swinging them with deadly precision.
Hadrian and Dante split up, each attacking from a different angle to keep Argosax off balance. Hadrian lunged forward, his twin blades flashing as he carved through the demon's armor-like skin. With each strike, Kanshou and Bakuya resonated with a deeper power, their edges glowing with a fierce light.
Meanwhile, Dante activated his full Devil Trigger, his body transforming into a demonic figure with wings and horns. He moved at blinding speed, striking Argosax with relentless force, his sword, and guns working in perfect harmony.
"Let's see how you handle this!" Dante roared, summoning his power to unleash a powerful, flame-laden spin attack that cut through Argosax's defenses, causing several of his grotesque limbs to disintegrate.
Argosax, now visibly weakened, let out a furious scream. His body began to change, revealing his true form—Despair Embodied. The creature's flesh turned a dark, metallic silver, and he took on a more humanoid shape, his body radiating raw demonic energy as he prepared for his final stand.
"This is it, kid," Dante said, his voice steely. "We either end him now, or he brings hell to the human world."
Hadrian nodded, determination blazing in his eyes. "Let's finish this."
Despair Embodied charged at them, his speed blinding. He lashed out with his wings, each beat of them creating shockwaves that tore through the battlefield. Hadrian barely dodged a wing strike, feeling the wind whip past him with lethal force. Hedwig shielded him with a barrier of blue flames, while Oryou fired concentrated energy blasts at Despair Embodied's core.
Seizing the opportunity, Dante flew forward, engaging Despair Embodied in a vicious melee. He parried the demon's attacks, his Devil Trigger form making him nearly invulnerable as he fought with unmatched fury. Hadrian joined in, flanking Despair Embodied and delivering powerful strikes to the demon's side, each hit causing cracks to appear in his armored body.
Together, Dante and Hadrian unleashed a synchronized assault, their combined power overwhelming Despair Embodied. In a final, desperate act, the demon summoned all his remaining energy, creating a massive orb of dark magic above him, preparing to obliterate them in a single strike.
"Hadrian! Now!" Dante shouted.
Hadrian drew upon his power, pouring every ounce of magic he had into Kanshou and Bakuya. The twin blades blazed with an intense, radiant light as he charged forward, leaping high into the air. With a mighty swing, he drove both blades into Despair Embodied's core, the force of his attack shattering the dark orb and piercing the demon's heart.
Despair Embodied let out a guttural roar, his monstrous form buckling under the power of Hadrian's final blow. His knees hit the ground with a thunderous crash, and he slumped forward, defeated, yet still flickering with the remnants of demonic energy.
Dante and Hadrian stepped forward, their expressions grim and resolute. In sync, they raised their guns—Ebony and Ivory in Dante's hands and Hadrian's enchanted Desert Eagles—aiming directly at the bowed head of the demon.
With the precision and unity that defined the bloodline of Sparda, both warriors pulled the triggers, their voices ringing out in perfect harmony:
""Jackpot!""
The bullets fired, tearing through the core of Despair Embodied with lethal accuracy. In an instant, the demon's form shattered into countless pieces, fragments of his essence scattering into the void, dissolving into oblivion.
As the last echoes of the battle faded and the remnants of Argosax vanished into the darkness, Dante and Hadrian exchanged a look—a silent acknowledgment of their shared triumph and the legacy they had upheld together.
