The Z Pirates (One Piece/Dragon Ball Crossover)

Sengoku's Vacation Home

Sengoku stared at the two men seated across from him at the dining table, his patience wearing thinner by the second.

For the past three days, he had endured their ridiculous presence in his home, questioning why he had ever bothered pulling them out of the ocean in the first place.

They ate without concern, taking up way too much space in his dining hall, their large frames dwarfing even the hefty wooden chairs beneath them.

Jinzo—formerly Android 8—was a hulking brute of a man, yet his mannerisms were strangely gentle. He ate slowly, carefully, as if making sure not to break the utensils in his massive hands.

Gevo—formerly Android 16—was taller, leaner, and far more methodical in his movements. Unlike Jinzo, who ate in quiet contentment, Gevo analyzed everything—from the texture of the food to the cutlery, to even Sengoku's mannerisms.

The Fleet Admiral sighed, rubbing his temple.

"Are you two done yet?"

Jinzo paused mid-bite, looking up like a guilty child. "I apologize. I was just enjoying the food."

Gevo, on the other hand, simply set his utensils down neatly, looking at Sengoku with a calm, calculating gaze.

"Your hospitality is appreciated, Fleet Admiral," Gevo said smoothly.

Sengoku grunted. "Hospitality, my ass. I was hoping you'd leave by now."

Jinzo frowned. "We have nowhere else to go."

That was another thing. Their story—or rather, their lack of one.

They had claimed amnesia, which in and of itself wasn't uncommon. The Grand Line was ruthless; people washed up all the time, barely remembering their own names.

But these two? Something about them felt… off.

For one, Conqueror's Haki hadn't affected them at all.

Sengoku had tested it several times over the past few days—just subtle bursts, nothing major—but neither of them had even flinched.

Most people would at least feel dizzy. Some would faint on the spot.

Gevo, instead, had asked what that strange energy was with the curiosity of a scientist.

Sengoku had, of course, lied. He wasn't about to explain Haki to two strangers who conveniently remembered nothing.

And then there were their names.

"Android 8" and "Android 16." As if those were actual names.

Sengoku had laughed at them outright, and to his surprise, the next day, they had taken on new names.

Jinzo and Gevo.

Sengoku wasn't sure if that made things less suspicious or more.

Gevo suddenly spoke, snapping him out of his thoughts.

"We want to become Marines."

Silence.

Sengoku blinked, slowly lowering his teacup.

"You what?"

Jinzo nodded, his deep voice calm but firm. "We wish to help people."

Sengoku leaned back in his chair, crossing his arms. "And where exactly did this decision come from?"

Gevo smiled faintly. "You explained how the Marines protect people. You also explained the dangers of pirates, the corruption in the world. If there is something we can do to help, then it is logical for us to align ourselves with the Marine cause."

Sengoku narrowed his eyes. "That simple, huh?"

Gevo nodded. "Yes."

The Fleet Admiral resisted the urge to pinch the bridge of his nose.

These guys… were too damn weird.

They were clearly powerful—even without knowing exactly what they were, Sengoku could tell they weren't normal. Their sheer presence alone was unnatural.

And they wanted to be Marines?

Most people hesitated before making a commitment like that. These two? They just decided it over dinner.

Sengoku glanced at Jinzo, who sat patiently, as if waiting for his decision.

Between the two, Gevo was clearly the one driving this decision. Jinzo just… followed.

But then again, there was something strangely pure about Jinzo.

Sengoku sighed. "You guys don't exactly have combat training, do you?"

Gevo tilted his head. "We do not recall any formal training. But…" He paused, flexing his fingers experimentally. "I believe we have natural instincts for battle."

Sengoku hummed. "That so?"

He wasn't convinced. At all.

The logical thing to do would be to send them away, tell them to figure things out on their own.

And yet…

Something told him not to.

He had seen talent before. He had personally scouted the greatest Marines in history.

And his gut feeling—the one that had never failed him—was telling him that these two were not ordinary men.

They weren't spies. They weren't schemers. They were something else entirely.

Sengoku sighed heavily, leaning forward. "Alright. Let's say I don't kick you out of here and actually let you join. What do you plan to do?"

Gevo met his gaze evenly. "We will train. We will serve. And we will protect."

Sengoku almost scoffed at how damn serious he sounded.

Jinzo nodded in agreement. "Yes. I do not like hurting people. But if I can protect others, then I will."

Sengoku ran a hand through his beard. These guys were too damn weird.

But fine.

He had a little test in mind.

"You wanna be Marines?" he said, standing up. "Then you train with the Marine cadets."

Gevo and Jinzo both straightened.

"I will not give you special treatment. You'll follow orders, run drills, and fight alongside other recruits. You fall behind? You leave." Sengoku's eyes hardened. "Got it?"

Gevo didn't hesitate. "Understood."

Jinzo nodded as well. "Yes, sir."

Sengoku grunted. "Don't 'sir' me yet. You haven't earned it."

He turned toward the window, looking out at the sea.

Perhaps… the world had given him these two for a reason.

He didn't believe in coincidences. Not at his age.

Maybe, just maybe…

They were meant to be here.

And if they truly had nowhere else to go…

Then he would make sure they found a purpose.

Marineford – Fleet Admiral's Office

Sengoku sat at his desk, rubbing his temple as he skimmed through the latest report.

It was supposed to be just another evaluation report—something he had read hundreds of times in his long career. Yet, this one was different.

His eyes flicked over the neatly written words, detailing the progress of two particular recruits.

Gevo and Jinzo.

Sengoku leaned back in his chair, a low hum escaping his lips. The results were… surprising.

Across from him, Instructor Board—a grizzled, no-nonsense veteran with more battle scars than patience—stood at attention, arms crossed over his broad chest.

The man was not one for exaggeration. If anything, he was known for being harsh, blunt, and painfully realistic.

Yet, here he was, practically singing praises about the two recruits.

"They're elites of the elite, Fleet Admiral." Board's voice was gruff but steady. "No other way to put it."

Sengoku raised an eyebrow. "That good, huh?"

Board nodded. "They started in the lieutenant-level training, like you ordered. At first, the others underestimated them—especially Jinzo, given his… slow demeanor." He hesitated before continuing. "That was a mistake."

Sengoku smirked faintly, already intrigued. "Go on."

Board adjusted his stance, his tone taking on a rare note of respect. "Jinzo might be a pacifist, but when pushed, he's a damn fortress. Man's got strength like an ox, maybe more. One of the lieutenants—an arrogant bastard—tried to take him down with a sneak attack."

Sengoku arched a brow. "And?"

Board chuckled dryly. "Jinzo didn't move an inch. Just stood there and took the hit like it was nothing. Then, when the guy tried again, Jinzo grabbed him—gently, mind you—and just… set him down on the ground like a misbehaving child."

Sengoku let out a low chuckle. That sounded about right.

"And Gevo?" he prompted.

Board's expression turned serious. "Now that one… he's the real deal."

Sengoku had expected that answer. Gevo had always given off a different kind of presence. Even when the man was simply sitting at the dinner table, he had an almost unnatural calm.

"How real are we talking?"

Board exhaled through his nose. "He's got instincts you don't teach. His reaction speed is off the charts, his technique is damn near flawless. I've seen plenty of prodigies, but he's different. He doesn't just fight—he adapts. He reads his opponent, counters them like he's done it a thousand times before."

Sengoku frowned slightly. "So, a natural?"

Board shook his head. "More than that. A natural talent still takes time to hone their skills. Gevo fights like he's been doing it for years. If I didn't know better, I'd think he had decades of battle experience under his belt."

That made Sengoku pause.

That wasn't normal.

He tapped his fingers against his desk. "You're saying he could become an admiral?"

Board exhaled. "If he keeps up this pace? Easily. The kid's got the mindset, the discipline, and the skill. Hell, he already fights on par with some of the senior lieutenants, and that's just after a few weeks of training."

Sengoku closed the report and folded his hands together, deep in thought.

It was as he suspected.

Gevo and Jinzo weren't ordinary men.

He had known that the moment they brushed off his Conqueror's Haki like it was a light breeze. That wasn't something even vice admirals could do.

And now?

They were outpacing trained officers in a matter of weeks.

Sengoku finally looked up at Board, his expression unreadable. "What do the others think of them?"

Board shrugged. "Mixed reactions. Some respect them. Some are jealous as hell. Others are just confused as to how two 'nobodies' are making them look bad."

"Anyone causing trouble?"

"A few, but Gevo shut that down real quick. He's smart—doesn't get emotional, doesn't start fights. But the moment someone tries to mess with Jinzo or anyone weaker? He shuts them down instantly."

Sengoku almost smirked. "And Jinzo?"

Board chuckled again. "He just takes it. Doesn't complain, doesn't fight back unless absolutely necessary. Honestly, I think some of the guys feel bad picking on him because he's so damn nice."

Sengoku sighed. "Sounds like they're settling in well."

Board nodded. "Yeah. And if you ask me? They're worth keeping an eye on. Especially Gevo. He's got that presence. The kind that makes men follow him."

Sengoku leaned back in his chair, exhaling deeply. That was the real issue, wasn't it?

Gevo wasn't just strong.

He had the aura of a leader.

And that? That was rare.

Sengoku finally stood up, walking over to his window, gazing out at Marineford.

Gevo and Jinzo had no past. No memories. Nothing tying them to the world.

And yet, they had adapted so seamlessly.

It wasn't just their strength.

It was their presence.

Sengoku didn't believe in fate. But maybe… just maybe, these two

And if Gevo truly had the makings of an admiral?

Then it was only a matter of time before the world took notice.

Sengoku exhaled through his nose, folding his hands on the desk as he fixed Board with a pointed look.

"That everything?" he asked, his voice even.

Board sighed, rubbing the back of his neck. "Not quite. There's… one more thing."

Sengoku gestured for him to continue.

Board shifted his stance before speaking. "During training, I demonstrated Rokushiki—the Six Powers—to the lieutenants. Gave them a basic rundown of each technique." He let out a dry chuckle. "Gevo… picked up Soru and Shigan almost instantly."

Sengoku raised an eyebrow. That fast?

Board nodded. "Yeah. Kid's got an uncanny sense of movement. It was like he already understood the mechanics of it before I even explained." He huffed. "Most trainees take weeks just to grasp the basics. But him? One damn day."

Sengoku leaned back slightly, processing the information. "And Jinzo?"

Board smirked slightly. "Surprisingly, he picked up Shigan too. Didn't expect that from someone like him. He's slow when it comes to decision-making, but his execution? Near flawless. Reminds me of Garp, honestly."

Sengoku's eyes narrowed slightly at the comparison.

Jinzo… was like Garp?

That was a bold statement.

Garp's fighting style was overwhelmingly physical, relying on pure strength and durability rather than technique. But if Jinzo was showing signs of similar raw power…

It meant he had the potential to be just as monstrous.

Sengoku exhaled through his nose. "And? What are you getting at?"

Board crossed his arms. "Well, I was wondering if I should start introducing them to Haki."

Sengoku's gaze sharpened. "You think they're ready for that?"

Board shrugged. "Lieutenants are taught about Haki at this stage. Whether they actually awaken it is a different story. Some take years, some never get it at all." He met Sengoku's gaze. "But if anyone's got a shot at picking it up fast… it's them."

Sengoku was silent for a moment, fingers tapping lightly on the wooden desk.

Gevo already had elite combat instincts and was adapting at an unnatural speed. Jinzo, despite his slow nature, was showing ridiculous physical capabilities.

Both of them were rising through the ranks far too quickly.

It was absurd.

It was a gamble.

But… it was his gamble.

Sengoku finally nodded. "Continue training them like the other lieutenants. If they qualify fully with speed and technique, I'll consider them for advanced training."

Board gave a small nod. "Understood."

Sengoku leaned back, his gaze shifting downward toward the open file on his desk.

Photos of Gevo and Jinzo stared back at him.

Neither of them had malice in their eyes.

They didn't look like schemers, manipulators, or ambitious upstarts clawing for power.

They were anomalies.

He hated relying on gut instinct. He preferred hard data—facts, reports, numbers.

But in this case… there was no data.

Nothing to compare them to.

Nothing but his own judgment.

His fingers traced the edge of Gevo's photo, his mind drifting.

There was a kindness in that man. A natural calmness.

The kind of calmness a leader needed.

Sengoku had spent years thinking about his successor.

It was a painful thought, but necessary.

Aokiji was the obvious choice. He had the charisma, the tactical mind, and the ability to rally people around him. But…

Akainu? Too rigid, too brutal. A frontline soldier, not a leader. He saw only absolutes.

Kizaru? Too laid-back. A man who followed orders, but never cared enough to give them.

And now?

Now he had Gevo.

A complete wild card.

Someone who could be a leader.

Someone who—if he continued at this unnatural pace—could rival the admirals themselves.

It would be funny, wouldn't it?

To see this nameless man, drifting in the ocean weeks ago, rise to the highest ranks of the Marines?

Sengoku smirked faintly.

"Alright then, Gevo…" he murmured under his breath.

"Let's see how far you can go."
