Multiverse Shenanigans: Raja's Journey

In the heart of a desolate battlefield, two titanic figures stood across from one another, each radiating an aura of pure strength and indomitable will. Mihawk's steely gaze met Kunia's fierce eyes, a mutual respect passing between them—a respect only warriors who have treaded the razor's edge of life and death could understand.

"Let's see how your Dragon Sword stands against Yoru, Dragon Empress," Mihawk said, his deep voice cutting through the silence.

Kunia smirked, gripping the hilt of her katana, Dragon Fault, its white and gold decorations gleaming. "And let's see if your title holds up, World's Greatest Swordsman."

In an instant, both figures lunged forward, their blades clashing with an earth-shattering clang. Sparks erupted from the collision as Mihawk's Busoshoku-coated Yoru met Kunia's Haki-enhanced Dragon Fault. Each warrior's Haki flared, creating a shimmering aura around them, an unspoken testament to the monumental clash that had just begun.

Phase 1: Testing the Waters

Kunia darted back, pivoting gracefully as she transitioned into her opening technique. "Serpent's Silent Fang!" She lunged with the speed of a striking snake, her katana aiming for Mihawk's vitals with lightning precision. Mihawk, however, anticipated her move with his Kenbunshoku Haki, stepping aside and countering with a swift, controlled slash.

"Quincy Cross!" Mihawk's Yoru released a wide arc of energy, slicing through the air like a guillotine. Kunia sidestepped at the last second, feeling the raw power of the attack as it carved a deep gash in the earth where she'd stood moments before.

Their weapons clashed again, and Kunia swiftly transitioned into her second technique. "Beast's Savage Tempest!" She launched a flurry of heavy, relentless slashes, the force of her strikes sending tremors through the ground. Mihawk met each blow, his expression unchanged as he matched her power for power, his blade absorbing the impact without wavering.

"Impressive strength," Mihawk commented, his tone calm and analytical. But as he blocked her final strike, he swiftly retaliated. "Black Hawk Slash!" A torrent of slashes erupted from Yoru, each one carrying the deadly precision and swiftness of a hawk. Kunia leaped back, evading with barely a hair's breadth of space as the attack razed the ground beneath her.

Phase 2: Heightening the Battle

Kunia's breathing steadied as she shifted her stance, her eyes narrowing. "Thunderbolt Impulse!" She moved so swiftly it seemed as though she teleported, her katana a blur as it aimed directly for Mihawk's heart. But Mihawk's Observation Haki was unparalleled; he stepped aside just as her blade grazed his coat. His sword swung in retaliation.

"Black Blade Strike!" Mihawk's Yoru was now fully coated in black Busoshoku Haki, shimmering with a lethal energy. He swung the blade in a calculated arc, aiming to end the battle in one decisive move. Kunia barely managed to block, her arms trembling under the pressure of Mihawk's strength.

Undeterred, she let out a fierce cry. "Thunderstorm Torrent!" She countered with a flurry of slashes infused with both Thunder and Beast Breathing, each strike aiming to overwhelm Mihawk with sheer speed and ferocity. Mihawk, however, remained calm within the storm of strikes, effortlessly parrying each one.

"Eye of the Storm," Mihawk said, his voice carrying a hint of respect. His sword moved in a fluid, circular motion, creating a defensive barrier that deflected each of Kunia's slashes, no matter the direction. She growled in frustration, but her gaze remained sharp, determined.

Phase 3: The Heat of the Battle

Kunia leapt back, her chest heaving. "You're strong, Mihawk," she admitted, wiping sweat from her brow. "But I'm just getting started."

With a fierce yell, she invoked her ultimate technique. "Dragon's Wrath!" Her katana surged with energy as she combined all her elemental breathing styles—Serpent, Beast, Thunder, and Mist—into a single, devastating attack. She closed the distance between them with incredible speed, her blade slicing through the air with deadly intent.

Mihawk's eyes sharpened as he recognized the level of power she was wielding. His grip tightened on Yoru. "World's Greatest Slash." He channeled his Haki and will into a single, ultimate slash. The two attacks collided, creating a blinding explosion of energy that tore through the battlefield, sending shockwaves in all directions.

As the dust settled, both warriors stood a few meters apart, each breathing heavily. Mihawk looked down at a cut on his sleeve, a rare sight indeed. Meanwhile, Kunia had a thin line of blood on her cheek.

"Not many can land a hit on me, Kunia," Mihawk said, a hint of admiration in his voice. "You're indeed worthy of the title Dragon Empress."

Kunia's lips curled into a smile, but she wasn't finished yet. "I'm honored, but I won't rest until I've bested you."

Phase 4: Pushing Each Other to the Limit

Mihawk took a deep breath, raising Yoru with a deadly focus. "Raven's Roar!" With a powerful sweep, he sent a wave of concentrated slashes hurtling toward Kunia, each one infused with his Haoshoku Haki. Kunia's own Conqueror's Haki flared in response, creating a forcefield that partially deflected the attack, though the sheer power behind it forced her back.

"Fine, then!" Kunia shouted, her eyes blazing with determination. She disappeared into a thick mist, her form vanishing entirely.

"Mist's Phantom Veil!" Hidden in the fog, she maneuvered swiftly, striking from unpredictable angles. Mihawk's Kenbunshoku Haki allowed him to track her movements, but her swift attacks from within the mist kept him on his toes.

But Mihawk was unfazed. "Eternal Night." His voice was calm as he channeled an overwhelming wave of dark energy into Yoru. He swung his sword, dispersing the mist with a powerful slash that seemed to blot out the sunlight for a split second.

Kunia reappeared, breathing heavily but still determined. She was met with another attack. "Rivers of Blood!" Mihawk slashed in a blur, his strikes so fast that the air itself seemed to tear around them. Kunia's Observation Haki barely kept up as she dodged, feeling each blade pass mere inches from her skin.

Final Phase: A Mutual Respect

As the sun began to dip below the horizon, both fighters slowed, neither willing to relent but both beginning to recognize the opponent's unmatched skill. Kunia prepared one last attack, her grip tightening on Dragon Fault. She charged forward with a roar, channeling all her strength into "Serpent's Lash of Thunder!" Her blade zigzagged through the air, combining agility and speed in a flurry of unpredictable strikes.

Mihawk met her charge head-on, his body moving almost instinctively. "Crossfire!" He unleashed a series of rapid, precise strikes, each one intercepting her attack perfectly, creating a blinding display of sparks as their swords clashed in rapid succession.

The two separated, breathing heavily, their gazes locked. Though neither had claimed victory, both knew the battle had reached its natural conclusion.

Kunia, chest heaving, lowered her sword. Mihawk, too, let Yoru rest at his side, a small but genuine smile forming on his face.

"You have extraordinary talent," Mihawk admitted, his voice devoid of its usual coldness. "With a few more years of training, you may very well reach my level."

Kunia smirked, though her exhaustion was evident. "I'll take that as a promise, Mihawk. Five years from now, I'll stand before you again, stronger than ever."

Mihawk nodded, impressed by her resolve. "I look forward to it, Dragon Empress." He sheathed Yoru, turning to leave. The battlefield, once filled with deadly intent, now bore the quiet mark of mutual respect.

As the last rays of the sun dipped below the horizon, Kunia watched Mihawk disappear into the distance, her heart alight with renewed purpose. Five years. It was a challenge, and she intended to meet it, no matter the cost.
