(Present)

Percy froze for a moment, her instincts screaming at her to bolt again. She didn't want to look at Poseidon's expression any longer, fearing it would send a tremor of terror through her. But as she turned to swim for her life once again, Poseidon's voice stopped her.

In a tone that cut through the silence like a blade, Poseidon spoke. "Since you so badly want to return to your world, I'll let you go."

Percy whipped her head around, her eyes widening in surprise. "Really? You'll let me go?" Her voice was a mix of hope and disbelief.

Poseidon nodded, and Percy saw that his gaze was chillingly cold. "But under one condition: You must defeat me in a fight. If you lose, you will stay by my side, permanently."

The words hung in the water like a heavy fog. Percy's heart sank. She had hoped for a simpler escape, but the idea of fighting Poseidon—an immortal god with untold power—was daunting. The challenge was both a glimmer of hope and a chilling reminder of the formidable force she was up against.

She took a deep breath, steeling herself. The prospect of facing a god like Poseidon, who was not her own father, was terrifying, but she knew she had no other choice.

She had to get out of this world.

She had to see her friends, family, and the love of her life again.

She had to take him on.

Steadying her nerves, Percy met Poseidon's gaze with a newfound resolve, pushing past the fear that threatened to overwhelm her. Her voice rang out with a confidence she didn't entirely feel, but she knew she had to project it.

"Fine," she said, her tone firm. "I'll fight you. If defeating you is the only way to get out of here, then I'll do it."

Poseidon's expression grew darker as he watched Percy's defiant stance. With a frustrated sigh, he raised his hand and conjured a small whirlpool of water. From the swirling depths, Riptide, Percy's trusty sword, emerged, its blade gleaming with a renewed edge.

"Riptide!" Percy exclaimed in shock, not expecting her sword to appear.

"Since you are eager to fight," Poseidon said, his tone icy as he tossed the sword toward Percy, "you can take this back."

Percy easily caught Riptide, her grip tightening around the familiar hilt. The weight of the sword felt reassuring in her hand, a reminder of her strength and her will to fight. She looked up at Poseidon, her eyes burning with determination.

The sea tyrant's gaze remained unwavering as he watched Percy prepare herself. The water around them seemed to grow completely still, the tension in the air palpable. The vast underwater realm stretched out behind him, contrasting with the battlefield that was about to unfold.

Percy gripped Riptide tightly, her knuckles whitening. She felt the familiar weight of the sword grounding her, its presence a reminder of her strength and the battles she had fought before. She took a deep breath, centering herself as she faced the god.

Poseidon's form shimmered momentarily, his divine aura radiating a powerful, almost oppressive force. He drew his own weapon—a trident that seemed to pulse with a deep, ancient energy. The trident's three prongs glinted menacingly as Poseidon held it with casual ease, a stark reminder of his immense power.

"Are you ready?" Poseidon's voice was a low rumble, almost drowned out by the distant echoes of the sea.

Percy nodded, putting on a brave face. "I'm ready."

Without further warning, Poseidon lunged forward, his trident cutting through the water with incredible speed. Percy barely had time to react, raising Riptide in a defensive stance. The clash of their weapons resonated through the underwater expanse, sending shockwaves that disturbed the surrounding sea life. The startled hippocampi swam away, fish scattered in a frenzy, and seaweed whipped around them.

Poseidon's strikes were relentless and precise, each thrust of his trident aimed to break through Percy's defenses. She parried and dodged, her heart thumping wildly as she fought to keep up with the god's formidable speed. Poseidon's fluid grace made him a blur in the water, his divine strength magnifying every movement.

The force of their battle was immense. Each clash between Riptide and the trident sent powerful ripples through the sea, shattering nearby underwater boulders. One particularly massive boulder cracked under the weight of their powers, its fragments exploding into a cloud of debris that scattered across the sea floor. The tremors from the impact sent a shiver through the ocean bed, highlighting the sheer scale of their confrontation.

Poseidon then shifted his tactics, summoning a colossal wave that surged toward Percy with terrifying force. Percy reacted swiftly, using her hydrokinesis to divert the wave. She formed a swirling barrier of water that absorbed the brunt of the impact, but the force nearly drove her backward. The wave crashed against her shield, the water spraying around them in a frothy explosion. Even with her breathing labored, Percy moved gracefully, her tail cutting through the water as she closed in on Poseidon.

She swung Riptide with precision, the blade slicing through the water with a gleaming arc. Poseidon blocked her attack with a wave of his hand, sending a spray of water that collided with Riptide. The impact created a shockwave that rippled through the sea, sending smaller underwater rocks tumbling across the sea floor. Poseidon's divine energy seemed to clash with Percy's elemental control, each hit creating a symphony of chaos and power.

The god of the sea retaliated with a flurry of rapid, powerful strikes. His hands wove intricate patterns, summoning torrents of water that lashed out at Percy with relentless fury. She countered by solidifying the water into crystalline formations, erecting barriers of ice that absorbed and deflected Poseidon's attacks. The ice glinted in the underwater light, creating a dazzling display of frozen artistry as it held firm against his onslaught.

Percy's movements were a blur of agility and precision as she wielded both her hydrokinesis and Riptide. She launched shards of ice with deadly accuracy, each projectile aimed to disrupt Poseidon's concentration. Poseidon's eyes narrowed as he dodged and deflected the ice shards, his frustration growing. The sea around them became a battlefield of glistening ice and churning water, a stark contrast of elements in constant collision.

The battle raged on, each combatant pushing their powers to their limits. Poseidon's divine strength manifested in colossal waves and whirlpools that threatened to engulf Percy. Percy responded with equal fervor, her cryokinesis freezing the water into treacherous obstacles and solidified barriers that shielded her from Poseidon's relentless attacks. The sea trembled with the force of their clash, each movement creating new currents and shifting tides.

Poseidon then summoned a vortex of water, a swirling maelstrom that threatened to engulf Percy entirely. She fought against the powerful current, transforming the vortex into a spinning storm of ice and water. The swirling vortex became a blizzard of frozen shards, whipping around them with a fierce, biting cold that numbed even the god's divine form.

The demigod pressed her advantage, using Riptide to slice through the icy storm and target Poseidon directly. The sea god struggled to maintain control, his focus shifting between the swirling ice and Percy's relentless attacks. Despite his immense power, the sheer force of Percy's elemental control was actually pushing him to his limits.

Poseidon could feel his pulse quicken. With a shark-like grin, a mix of lust and obsession swirled in his eyes.

Yes! This is exactly what he expected of her!

His daughter is powerful, and with such strength, only she can be his wife!

However, she would not defeat him!

He unleashed a massive wave of energy. The wave crashed against Percy with overwhelming force, sending her spiraling through the water. She fought to regain her balance, her breath coming in ragged gasps as she prepared for another attack. Her vision swam with the force of the impact, but she tightened her grip on Riptide, remaining unshaken.

The battle seemed to reach its peak, both combatants locked in a fierce struggle that threatened to overwhelm their surroundings. The water around them was a chaotic whirlwind of energy and power, each clash sending shockwaves through the sea.

Just as Poseidon prepared to deliver a blow that would not kill her but incapacitate her, a sudden, piercing voice cut through the tumultuous water, halting both fighters in their tracks.

"STOP THIS AT ONCE!"
