Dressrosa, New World
The training ground trembled with each impact — dull, thunderous cracks echoing off the stone walls as fist after fist slammed into the massive slab of raw seastone ore. Dust shook loose from the ceiling. The smell of iron — blood and sweat — hung thick in the air.
In the center of it all stood a young girl, no older than twelve. Her long, white hair shimmered under the dim torchlight, bound behind her head by orange rods into a wild ponytail that faded into shades of aqua green and ocean blue, ending in rectangular locks that swung like banners of storm-tossed waves.
Twin horns jutted proudly from her head — red at the tips, softening to a flesh tone near the base — the mark of her cursed lineage. Her large, amber-orange eyes glowed like molten gold beneath furrowed brows, sharp with fury and grief far beyond her years. Golden hoops hung from both ears, glinting faintly as she moved.
A kanabo — its spiked body scarred from countless battles — rested at her side, only an arm's
reach away. But Yamato didn't touch it. Not yet. She didn't need a weapon. Not for this. Her fists — small, bloodied, trembling with exhaustion — were enough.
The unrefined seastone tore into her flesh with every strike. The jagged edges shredded her knuckles raw, numbing her arms until they felt like lead. Each punch drained her strength further — the curse of seastone greedily devouring the energy of her body — yet still she refused to stop. Every blow was a cry, every impact a curse hurled toward the specter that haunted her soul.
Kaido.
The name burned through her like acid. Her teeth clenched. Her vision blurred. Pain screamed through her arms, but she didn't flinch. She welcomed it — needed it. This agony was her crucible, her only proof that she was still alive, still fighting.
"One day…" she whispered through gritted teeth, breath ragged, voice trembling with hatred, "…one day, I'll kill you."
The words came out more like a vow than a threat. Blood splattered against the stone, mixing with the fine dust. Her knuckles split open again as she struck harder, faster, each blow fueled by the storm raging inside her. The sound was deafening — flesh against stone, heart against destiny.
Yamato's body moved on instinct now, abandoning form and discipline. Issho's teachings — the calm, centered breathing, the flow of motion through the body — were forgotten. She was no longer the student who sought balance. She was the beast born of rage and loss, clawing at the shadow of the father who had destroyed her world before she even had a chance to live in it.
The ground beneath her began to crack. Her fury pulsed through the air like heat, raw and suffocating. Even at her young age, there was something monstrous in her — a spark of that same overwhelming presence that had once shaken the world. But unlike Kaido's domination, Yamato's power burned with rebellion.
Each strike carried with it a piece of her soul — her loneliness, her guilt, her hatred, and her desperate longing to be free of it all. She could still hear his voice in her nightmares, still see the smirk that mocked her weakness, still feel the chains that had bound her since birth.
The faint echo of knuckles against stone faded into silence — replaced by a calm, almost melodic voice that cut through the tension like silk through steel.
"If you keep this up, you'll destroy your fists long before you ever find real strength…"
Yamato froze.
Her instincts screamed. Someone was here. And yet — she hadn't felt them arrive. Not a whisper of movement, not a flicker in the air, nothing to betray their presence. She had chosen this place precisely for its solitude — an isolated training chamber carved into the cliffside at the edge of the bay, where even the crashing waves of Dressrosa seemed distant. Only Issho-san and a few others knew she trained here.
How had this stranger entered without her noticing? Her body moved before her mind caught up — pure reflex. Her hand snapped toward the kanabo resting by her side, fingers curling around its handle with the ease of someone born to wield destruction. The weapon hummed with life the moment she touched it, responding to her fury as black lightning crackled faintly across its surface.
Yamato's blood roared in her ears. She didn't even think — she simply moved.
Her armament haki flared, coating the kanabo in a dense, obsidian sheen. And then — as if some deeper instinct within her awakened — a different power surged forth. The air around her warped, rippling like the surface of a storm-tossed sea as threads of Haoshoku Haki danced around the club in chaotic arcs of black and violet lightning.
It wasn't deliberate. It wasn't controlled. It was instinct. The raw, untamed conqueror's spirit of a child who refused to kneel before fate. With a roar that echoed through the chamber, Yamato swung — a perfect, furious strike aimed squarely at the intruder's skull. The weapon screamed through the air, splitting it apart with sheer force.
The figure didn't move.
"Boom!"
The sound thundered across the room as the kanabo met something unyielding — but it wasn't flesh, or bone, or armor. It was a hand. Bare. Unharmed.
The man before her — calm, expression unreadable — had caught her strike effortlessly in his palm. The impact sent shockwaves through the stone walls, dust and pebbles raining down from above. The ground fractured beneath their feet, web-like cracks spreading outward from where he stood.
But the man didn't even flinch. The air between them still crackled with the remnants of her Haki — invisible lightning snapping and biting at his skin — yet he remained utterly unmoved, as if he had simply swatted away a passing breeze.
Mansherry, perched on his shoulder, flinched at the burst of force and instinctively grasped a lock of his hair to steady herself. "H-Hey! Be careful!" she began to yell — but stopped when she realized he hadn't taken a single step back.
Yamato's eyes widened, disbelief flashing across her face. Her attack — her full strength — the culmination of everything she had learned, everything she had poured into that one strike — hadn't even made him blink.
Her breath hitched. Her knuckles trembled around the kanabo's handle, still pressed uselessly against the man's open palm. Then, slowly, he lifted his gaze — and she saw his eyes.
They were calm, impossibly calm, yet behind them was a depth she couldn't measure — like staring into the abyss of the ocean and realizing it was staring back. Haki radiated from him not as a flare but as a tide — smooth, absolute, eternal. He had seen her coming long before she had even moved.
The weight of that realization hit Yamato harder than the pain in her fists ever could. The difference between them wasn't just power — it was presence. A gulf so vast that even her rage, her defiance, her inherited strength felt like a flickering candle before a storm.
The stranger finally released her weapon, letting it fall back into her grip. The echo of the earlier impact still sounded almost like judgment.
"Your spirit's impressive," he said quietly, his voice carrying no mockery — only certainty. "But raw rage alone… will never bridge that gap. I am sure Ishho-san must have taught you that already…"
For a long moment, Yamato could only stare — chest heaving, heart pounding, eyes locked on the man who had effortlessly halted the storm she had unleashed. Then the recognition hit her — the weight of who she was looking at. Her breath caught in her throat.
"…You—"
The word never fully formed. She could only stare, wide-eyed and silent, as the realization sank in. The chasm between them wasn't just strength — it was something greater. Something divine. And for the first time in a long while, Yamato felt something other than hatred or rage. She felt awe.
The silence that followed was heavy — not with fear, but with revelation. As the dust settled, Yamato's wide, trembling eyes locked onto mine. I could see the recognition dawn within her, like the first rays of dawn cutting through an endless storm. Her lips parted, a single breath escaping — half disbelief, half wonder.
Because standing before her was the man she had crossed hell itself to find, Donquixote Rosinante.
The man who, years ago, had brought Kaido — the so-called Strongest Creature Alive — to his knees with a single swing of his blade. The man whose name and image had been burned into her very soul and every bounty poster the Beast Pirates tried to destroy. The golden-haired "ghost" whispered about in the underworld — a man who stood at the very apex of this world.
But for this girl… I was something else entirely. To Yamato, I wasn't just Rosinante. I was her reason. Her light in the darkness. The beacon that had guided her through the suffocating chains during most of her captivity — the proof that monsters could bleed, that tyrants could fall.
And now, that very figure stood before her in the flesh. Her kanabo slipped from her hand with a hollow thud, rolling across the stone floor. Tears welled up in the corners of her fiery orange eyes as her expression crumbled — rage melting into awe, hatred into trembling reverence.
Then, before I could speak, she dropped to her knees.
"Master!"
The word tore from her throat like a prayer long held in silence. Her forehead nearly touched the ground as she bowed, her white-and-aqua hair spilling across the cracked floor, streaked with blood and dust. The sound of her voice — so small, so full of devotion — cut deeper than any blade.
I froze. For all my years of war, all the titles and blood that had followed my name, this… this was what made me falter. Yamato was only a child — twelve at most. Her hands were still raw from striking seastone, her knuckles split and bruised. And yet here she was, kneeling before me like a knight before her god.
I scratched the back of my neck, feeling my face heat in embarrassment. Mansherry giggled softly from my shoulder, her tiny hand covering her mouth.
"…Ah," I exhaled, forcing a smile, though the weight in my chest made it difficult. "You know, I'm really not used to children calling me that or acting in such a way...!"
But she didn't move. Her back stayed straight, her gaze unwavering. There was a fire in those eyes — fierce, desperate, unshakable. The kind of conviction that made even the strongest men hesitate.
I wanted to tease her. I wanted to say something light — something to break the weight of the moment. Maybe a quip, like 'I don't recall ever accepting you as my disciple, you know.' But when I met her eyes, the words died in my throat.
Because there was nothing childish in her gaze. Only a soul forged by suffering and lit by faith. I sighed, my shoulders relaxing as I crouched slightly, bringing myself to her level. The air still crackled faintly with the remnants of her Haoshoku Haki — wild, uncontrolled, full of promise.
"So," I said at last, a small smile tugging at my lips. "You're the one who's been waiting all this time, huh? The one who swore she'd find me and become my student."
Yamato looked up — and for the first time, the fierce warrior child looked every bit the lost girl she truly was beneath the armor of vengeance. Her lips quivered, but her voice, though small, carried the same weight that had echoed through her fists moments ago.
"Yes… Master."
Her hands clenched tightly on her lap, still streaked with blood. "I've been waiting for you to return. I've trained every day. I've fought my father's men. I swore that one day I'd be strong enough to stand before you."
The words struck something deep inside me. In that moment, I didn't see Kaido's daughter — I saw a child fighting a battle the world had forced upon her. A reflection of every soul crushed under tyranny, clawing toward a dream that might never come.
I placed a hand gently atop her head. Her hair was still damp with sweat and salt, her body trembling faintly — not from fear, but from restraint.
"Then stand up, Yamato," I said softly, the faintest warmth threading through my tone. "A warrior of your spirit shouldn't kneel for anyone. If you truly wish to learn from me and be my student… then let your fists speak again. But this time—" I smiled, a faint edge of mischief in my voice. "—try not to aim for my face."
Little Mansherry snorted — a soft, bell-like sound that bounced around the quiet training chamber — unable to contain her laughter. Yamato blinked, the confusion flickering across her face slowly giving way to realization.
And then, it hit her. The words I had spoken — " my student." Simple, almost offhanded… yet to her, they were salvation. Her lips trembled as her orange eyes went wide, and before she could form another word, the dam inside her broke.
Tears — hot, heavy, long-suppressed — spilled down her cheeks. Her breath came out in short, uneven gasps, a choked sound tearing through her throat as she tried to speak, to thank me, to say something—but nothing came out except raw, unfiltered emotion.
All the walls she had built — the grit, the rage, the burning hatred that had kept her alive — cracked and crumbled in an instant. Because for the first time since the day her world became a cage… She wasn't alone.
For the first time in her young life, she wasn't Kaido's daughter. She wasn't the "Beast's Spawn."
She was simply Yamato. A little girl who, deep down, had only ever wanted someone to stand between her and the storms — someone to tell her she didn't have to fight the world alone.
And as I stood before her, I saw that facade of the warrior melt away, revealing the frightened, weary child beneath it all. The hands that had been so tightly clenched in defiance now trembled openly, her shoulders shaking as sobs wracked her small frame. The sound of her crying filled the chamber — raw, honest, human.
Mansherry, bless her heart, didn't say a word. She simply slid off my shoulder and waddled over to Yamato, her tiny tail swaying softly as she placed her glowing hands over the girl's torn, bleeding knuckles.
Warm golden light bloomed — soft and pure — wrapping around Yamato's hands like a mother's embrace. The bleeding stopped, the raw flesh knitted back together, leaving behind only faint scars that glimmered in the light. But I knew better. Those scars would never truly fade — not the ones carved into her heart. Yamato tried to speak between her tears, her voice breaking.
"B-but you should know… I'm Kaido's—"
I didn't let her finish. I crouched down before her and spoke softly — the kind of tone that came not from command, but from understanding.
"I know who you are," I said. "And it doesn't matter to me." Her breath hitched. I let my gaze soften, resting a hand gently on her shoulder. "It doesn't matter that you're Kaido's daughter. It doesn't matter what blood runs through your veins or what name the world calls you by. What matters…"
I paused, letting the weight of the next words settle between us like a sacred vow. "…is that from this moment on, you're one of us. You're family. The Donquixote family is your home now — your true home. And no one, not even the shadow of that monster, can take that from you."
Yamato stared at me, her lips parting slightly as if she couldn't quite believe what she'd heard. The storm in her eyes — the one that had always been there, raging and untamed — seemed to still for the first time.
Her small hands, still glowing faintly from Mansherry's healing touch, clenched over her chest as if to hold onto those words, to keep them safe.
"…Family," she whispered, her voice barely audible.
The tears began anew, but they were different this time — softer, freer. The tears of someone who had finally stopped running.
I stood, straightening my coat, pretending not to notice the tightness in my own throat. "Now then," I said lightly, forcing a small smile. "If you're going to cry every time I compliment you, our training's going to take forever, you know."
Mansherry giggled, shaking her head at me. But Yamato only laughed through her tears, the sound rough and uneven but pure — the laughter of a child rediscovering what it meant to feel safe. For a heartbeat, the heavy air lightened.
But even as her laughter echoed faintly in that lonely hall, I saw it — deep within her eyes, beneath the relief and the warmth, the storm still lingered. Hatred, grief, longing — all coiled together into something unbreakable.
"By the way," I said casually, brushing the dust from my coat as Yamato stood up, doing her best to hide the last traces of her tears, "you should know — I already have two other students. I'm sure you've heard of one of them… Lucci."
At that, Yamato's brows furrowed slightly. Even in the New World, Lucci's name carried weight — a prodigy whose cold precision in combat had already begun to stir whispers.
"The other," I continued, my tone softening, "is much younger than you. Her name is Kuina. Maybe someday, the two of you will meet."
Yamato nodded quietly, her small hands curling into fists at her sides. There was no jealousy in her eyes — only resolve. She wasn't the kind to be discouraged by rivals. If anything, the idea of others who had earned my tutelage only strengthened her conviction to walk this path.
But the truth was — taking Yamato under my wing wasn't a whim born of pity or sentiment. No, it was because she possessed something rare — something that even among monsters, stood apart.
Her will.
Even at twelve, Yamato was a creature of contradiction — fragile and furious, broken yet unyielding. And like Lucci, she carried within her the makings of a true calamity — a monster in the making. But what truly set her apart… was her affinity for Haoshoku Haki.
Without any structured guidance, she had already managed to project it, infuse it, shape it — to wrap it around her weapon instinctively. Most Conquerors never achieved that in their lifetime, and yet here she was, a child who could let her spirit crash against the world like a tempest. Her Armament Haki wasn't quite there yet, but the fact that her Haoshoku overshadowed it spoke volumes about the depth of her potential.
This girl wasn't destined to merely inherit power. She was born to rewrite it.
"Ross," Mansherry piped up suddenly, tugging at my ear with that mischievous grin of hers, "aren't you going to give your new student a gift?"
I shot her a flat look. "A gift? Really?"
The little troublemaker only giggled and hopped back onto my shoulder, her tiny frame fluttering. "Of course! Every great master gives their disciple something to remember them by."
I sighed, pinching her cheek lightly — to which she squeaked and pouted — then turned my gaze back to Yamato. The girl had straightened her back, orange eyes wide and glimmering with curiosity. For someone who had grown up surrounded by chains and beatings, the word gift might as well have been a foreign language — and yet, she looked at me now with the kind of anticipation only a child could muster.
"Well," I mused aloud, pretending to think hard, "you're not a swordsman like me… and I can tell you favor the Kanabo more than any blade. You already have a Devil Fruit too, so that rules out a mythical Zoan. Hm…"
Mansherry chirped again, ever eager to interfere. "Why don't you just ask her?"
I chuckled. "Suppose that works too."
Turning my gaze to Yamato, I asked, "Tell me then, Yamato — what do you want?"
Her eyes widened a fraction, clearly not expecting the question to be turned back on her. She hesitated, rubbing her freshly healed knuckles together, before finally blurting out in a soft but steady voice.
"C-can you teach me how you did that, Master?"
I arched an eyebrow. "How I did what?"
She swallowed hard, her eyes burning with earnest curiosity now. "How you managed to approach me without me noticing… even though I was using my Observation Haki. My Haki's not weak — I should've sensed you. But I didn't. And when you caught my Takeru…"
She paused, her voice trembling with both awe and confusion. "It felt like my body was being… suppressed. Like I was standing too close to Kairoseki. My strength — my very spirit — just… shrank. What was that? Is it something I can learn too?"
Her words hung in the air, her tone a mix of fascination and hunger — the same raw desire I had once seen in Lucci's eyes, in Kuina's blade, in every soul desperate to touch the unreachable.
I studied her for a moment — this little girl with the horns of a demon and the heart of a storm. Her eyes, those fierce orange flames, looked at me as if the entire world rested on my answer. A slow smile curved my lips.
"You felt it then," I said quietly. "Good."
I let my Haki stir — not a burst, not a wave, but a mere whisper. The air trembled, shadows bending just slightly, like the room itself was holding its breath.
"What you felt," I said, my voice steady but quiet enough that the flickering lantern light seemed to lean in to listen, "was the weight of will."
Yamato's eyes lifted to meet mine — bright, molten orange, still trembling with a storm of curiosity. "I'm sure Issho has already taught you most of the fundamentals of Haki, yes?" I asked.
She nodded instinctively. "Yes, Master. Kenbunshoku, Busoshoku, Haoshoku… and their intermediate and advanced forms. He showed us how to project armament outward, to destroy from within, to feel emotions and glimpse the future… and even to let my will clash and entangle with another's through Haoshoku."
A small smile tugged at my lips. "So he has been thorough, then. That man never does things halfway." But then I shook my head, stepping closer until her reflection shimmered faintly in my eyes. "Still… what I showed you just now — that wasn't any of those. What you felt wasn't simply 'advanced' Haki. It lies beyond that realm — in a space that very few have even brushed against."
Yamato tilted her head slightly, those horned shadows shifting across the floor as she frowned. "Beyond…?"
"Yes." I folded my arms, my tone turning almost reverent. "You see, Haki isn't just a weapon — it's an extension of one's soul. And like the soul, it can evolve infinitely if you can push past the limits of self."
I raised a hand, fingers curling lightly as the air around me dimmed — not with pressure, but absence. It was as if the world itself forgot I existed. Even Yamato, who was staring right at me, felt her senses blur for the briefest moment — that eerie, hollow silence where even her observation Haki couldn't feel me.
"The first," I said, my voice resonating through that quiet void, "is an evolved form of Observation Haki — a mastery where one's will folds perfectly into the world around them. Instead of reaching outward to sense, it retreats inward — erasing your existence entirely. It's not concealment through power, but through harmony."
Yamato's breath hitched; her senses screamed that I was standing right in front of her, yet every instinct said I wasn't there.
"With this," I continued, "even the sharpest Observation Haki cannot perceive you — not your breath, not your intent, not even your will. You become a void in the current of life. To the world's senses… you simply cease to exist."
I let the effect fade, and the air instantly rushed back into motion. Yamato stumbled slightly as her awareness snapped into focus, her chest rising and falling with uneven breaths.
"That's…" she whispered, awe coloring her voice, "…like becoming a ghost."
I smirked faintly. "A ghost of the living. And like all ghosts, it's a matter of acceptance — of dissolving your ego completely into the flow. It's not something easily taught. But it can be earned."
Her fists clenched, silent determination flaring in her eyes. I could already tell — she'd chase this secret until her knuckles bled again.
"But that wasn't the only thing you felt, was it?" I added softly.
Her eyes widened slightly as she recalled the earlier moment. "When you caught my Kanabo… it felt like my Haki was… dying. Like it was being eaten away."
I nodded slowly. Reaching to my side, I let my fingers brush against Akatsuki — the blade at my hip. Its black sheath shimmered faintly, humming like a restrained storm.
"That," I said, "is something I created on my own… after forming a deeper connection with Akatsuki. Just as this blade can devour Haki, I've learned to let my Busoshoku flow in the same way — not to clash with an opponent's Haki, but to consume it."
Yamato's expression tightened, trying to wrap her mind around the concept.
"It's a dangerous art," I admitted, my tone low. "Because to drain another's Haki, you must allow your own to intertwine with theirs completely — to open yourself to their flow while overwhelming it. One mistake, one moment of weakness… and you'll end up feeding your strength to them instead."
Yamato shuddered, both fascinated and terrified by the implication. "But when truly mastered," I continued, "it turns every clash into a harvest. Every blow you take… strengthens you. Every strike they land… weakens them."
For a moment, silence reigned — broken only by the faint hum of Akatsuki and the soft crackle of the lantern flame. Yamato stood motionless, eyes wide, as if she was staring at a chasm she could barely comprehend — and at the monster standing at the other end of it.
I looked at her then — really looked. This small girl, trembling between awe and defiance, still too young to understand what kind of world she wanted to stand against.
"You asked if you can learn it," I said finally. "You can. But power like this demands more than strength. It demands understanding. To erase your presence… you must first be at peace with your existence. And to consume another's will… you must first conquer your own."
Her fists tightened. Her voice, though small, was steady. "Then I'll do it. No matter how long it takes." A faint smile curved my lips — not of amusement, but of pride.
"I'd expect nothing less from my student."
The lantern light flickered again, casting our shadows across the cracked seastone slab — the shadow of a man whose will devoured even light, and a girl whose fury burned bright enough to challenge it.
