Today was the day Luffy would leave Foosha Village to begin his journey to become the King of Pirates. Makino and Dadan both wept as they bid Luffy farewell, holding onto him as though they were afraid he might disappear before their very eyes.
Standing off to the side, with a grin just as wide and reckless as Luffy's signature smile, was his big brother Kael D. Raen.
The third sworn brother of Luffy. Kael, the eighteen-year-old oni and buccaneer hybrid. He wore the same wild, infectious grin as Luffy. Kael, as he watched Luffy sail off, said, "Fly, little brother. The sea's waiting for you to shake things up." The fire-forged heart of Ace. The sharp, calculating eyes of Sabo. A storm made flesh, wrapped in a brother's quiet promise.
Dadan, tears streaked down her weathered face, looked to Kael with a mix of hope and sorrow. "Are you leaving us just like your other brothers now that Luffy is gone?" she asked, her voice thick with emotion.
Kael's smile softened as he shook his head. He grabbed a bottle of sake from a nearby crate and looked at her, the firelight reflecting in his crimson eyes. "Not yet, Dadan." His voice was low, resolute. With that, he turned and made his way toward his makeshift shipyard, the place where he had spent countless hours with Ace, Sabo, and Luffy.
The half-built ship stood at the heart of it all. Kael stopped before it, his eyes lingering on the unfinished vessel, the product of years of sweat, blood, and fury. He exhaled deeply, then began to sing an old sea shanty, one Shanks and his crew used to sing when Kael and his brothers were just kids, dreaming of the sea.
🎶 Leave her, Johnny, leave her…
For the voyage is long and the winds don't blow…
And it's time for us to leave her. 🎶
As the song faded into the still night, Kael's thoughts drifted to a time that felt distant, but painfully close. The memory of Ace's death at Marineford, his last words, the heat of the flames, the roar of Whitebeard's fall surged like a tidal wave, threatening to pull him under. He saw a future where his youngest brother was rising a storm against emperors, warlords, and ghosts of the old age. The Yonko. Marine Admirals. Everyone Luffy would face on his path.
And then, amidst the memories, a voice low, resonant, and unlike anything he'd ever heard before cut through the chaos.
"Kael D. Raen, you have awakened the strongest pirate system."
Kael's breath caught in his throat as he stiffened, hearing the voice again. It echoed through his mind like an old, familiar song. This was no dream.
"This system will allow you to summon five members of the One Piece world. One from the dead, one from the Roger era at their prime, and the final three at their current level. The system gives you tasks to upgrade your ship, gain random treasure maps, weapons, skills, and mythical devil fruits."
Kael froze mid-step as a circle of shadow and flame ignited beneath his feet. Crimson symbols spun around him, unseen by the world, but sharp as daylight to him.
A translucent interface materialized before his eyes, its words carving themselves into his mind like a brand.

Kael's heartbeat thudded in his chest. Emotions tangled and thundered inside: shock, wonder, and the wild pulse of excitement. He couldn't deny the pull of the adventure that beckoned before him. A chance to change everything. To write a new story, one where his brothers didn't have to die.

Kael's pulse pounded in his ears. "What the hell?" His thoughts swirled as the weight of what was happening hit him. The dreams. The memories of another world. One where Luffy's adventures had been stories—stories that had played out in ink and pages. He had seen Ace's death. Whitebeard's fall. He had felt the grief, the fury, the loss.
But this… this wasn't fiction.
This was real.
Kael clenched his fists, the air around him crackling like the calm before a storm. "No more deaths… Not on my watch."

Kael's hand hovered over Ace's name for a long, heavy moment.
The weight of it hit him, his thoughts flashing to Ace's fiery determination, his reckless smile. But Kael wasn't ready for that yet.
"No… not yet," Kael whispered. "He's got his story. I need to write mine."
His gaze shifted toward the base of the mountain, where his half-built ship waited, like a silent promise of what was to come.
A labor of solitude, of fury, scavenged wreckage, forest timber, and the brutal will of a Buccaneer's bloodline.

[Summoning…]
A thunderous shockwave of spiritual pressure tore through the forest, shaking the very earth beneath Kael's feet. Leaves scattered, trees groaned, and the air itself trembled as a portal of crimson flame and swirling shadow erupted before him.
From its depths, a tall, fierce-eyed woman emerged, silver hair cascading around curved horns, clad in furs and iron chains.
Her aura blazed with rebellion, strength, and untamed fire, the very essence of a warrior born to break chains.
Yamato's sharp eyes locked onto Kael's as her hand gripped the handle of her kanabō, Takeru. The weapon hummed with bloodlust, its edge gleaming with promise. Her gaze narrowed.
"What the hell…? Where am I?"
Kael stepped forward, his crimson eyes gleaming beneath his bandana. A wild grin curved his lips. "I'm Kael D. Raen," he said, his voice low, confident. "And I just summoned you."
Yamato tensed, her grip tightening on her weapon. "Summoned me? Who the hell are you?"
Kael raised a hand, cutting her off. "I'm not one of Kaido's dogs, and I'm not after your head. What I want… is a first mate."
Yamato's eyes flickered with surprise, her stance relaxing just slightly. She regarded Kael for a long moment, and he could see the fire in her eyes, the same fire that burned in his soul.
"I need a first mate who's as untamed as the sea itself. Someone who doesn't bend to anyone. Someone ready to conquer the world with me?
So, what do you say, Yamato? You in?"
For a heartbeat, there was nothing but the crackle of residual energy in the air, the tension thick enough to cut through.
Then, Yamato's lips quirked into a sharp, feral smile. "Tch… you've got balls, I'll give you that." She hefted her kanabō over one shoulder. "Alright, Captain, I'm in."
[New Crew Member Acquired: Yamato – First Mate]
Kael chuckled darkly. "Good," he said. "Let's go raise some hell."
AN: For his summons, they are the only version of that character.
