Chapter 8: Ambition Declared on the Astro Sunny
(Word count: 4,312)
The galley lanterns had burned low. Most of the Straw Hats had drifted away—some to bunks, some to night watch, some simply to stare at the impossible sky that now replaced the familiar Grand Line. Only a handful remained at the long table: Luffy (still eating), Nami (scribbling frantic star charts), Zoro (sipping sake in silence), Sanji (cleaning the stove with unnecessary violence), Robin (reading by candlelight), and Kai—sitting at the far end, back against the bulkhead, hands folded in his lap.
The rescued sky-islanders had been settled in spare hammocks below deck, tended by Chopper. Their soft, grateful murmurs had faded into exhausted snores. The ship rocked gently on invisible currents; the thrusters hummed a low, constant lullaby.
Luffy finally pushed his twentieth plate away and leaned back, both arms stretched behind his head. His straw hat sat crooked, shadowing half his grin.
"Man… I'm full. That was the best meat I've had since… uh… since the last time Sanji cooked!"
Sanji flicked ash from his cigarette without looking up. "Flattery won't get you seconds, idiot captain."
Luffy laughed anyway—loud, bright, filling every corner of the room.
Then he turned his head toward the quietest person at the table.
"Oi, Kai."
Kai looked up. Steady. No flinch.
"You've been on the ship for a whole day now. You saved people. You punched drones. You're strong. But you still haven't said the important thing."
Nami glanced over from her charts, eyebrow raised.
Zoro's sake cup paused halfway to his lips.
Sanji leaned one hip against the counter, arms crossed.
Robin closed her book with a soft sound.
Kai didn't blink.
Luffy's grin softened—just a little. Not less bright, but deeper.
"What do you want to do? I mean really. Not just 'fight the purple guys.' Everyone fights them now. What's your dream?"
The question landed like a stone in deep water. No ripples at first. Just weight.
Kai let the silence stretch exactly three heartbeats. Long enough to show he was thinking. Short enough to show he wasn't stalling.
Then he spoke—voice low, level, carrying no bravado and no hesitation.
"I want to sail every sea there is. Not just this one. Not just the Grand Line. Every sky. Every star. Every place the rifts open to. I want to see them all. Fight in them all. Eat in them all. And when I've seen enough… I want to stand on the deck of a ship that belongs to me and my crew, look back at every world we touched, and know we made them better. Freer. Not because we ruled them. Because we refused to let anyone else rule them either."
He paused.
Then quieter—almost under his breath, but loud enough for everyone to hear:
"I want to be the Pirate King… of infinite seas."
The galley went still.
Not the dramatic hush of shock. The kind of stillness that happens when something true is spoken in a room full of people who understand what truth costs.
Luffy stared at him for a long moment.
Then he threw his head back and laughed—deep, rolling, from the belly.
"Shishishi! Pirate King of infinite seas?! That's even bigger than my dream! I'm gonna be Pirate King of the Grand Line—now the Galactic Line! We can race! You and me—who gets there first!"
Nami groaned and dropped her forehead onto her charts. "Luffy… he just said he wants to be king of everything and you turn it into a contest?!"
Zoro smirked into his cup. "Another D. The seas really are getting crowded."
Sanji exhaled smoke through a half-smile. "Multiverse, huh? As long as you don't steal my ladies from other worlds, we're good."
Robin's eyes sparkled faintly. "The D. clan… and now a boy who dreams beyond one world. History is rewriting itself while we sit here eating."
Franky pumped one fist. "SUPER radical! We'll build a fleet that can sail every dimension!"
Brook strummed a single bright chord. "A song for the Pirate King of Infinity! I shall compose the greatest ballad the multiverse has ever heard!"
Kai didn't smile. He didn't blush. He simply nodded—once.
"Thank you."
Luffy reached across the table with a rubber arm and clapped him on the shoulder again—gentler this time.
"Then it's official. You're not just nakama. You're my rival for the biggest pirate crown ever! But we're still crew until one of us wins. Deal?"
Kai looked at the hand on his shoulder.
Then at Luffy's eyes—pure, fearless, absurdly certain.
"Deal."
The moment broke when Nami slapped her charts down.
"Fine. If we're doing this insanity, we need a plan. The purple ships are blockading the old Red Line. Reverse Mountain is gone—swallowed by that rift mess. We can't just sail home. We need to understand what those rifts are."
Robin turned another page. "They are not natural breaches. The energy signatures match nothing in the Poneglyphs or Vegapunk's notes. Something—or someone—tore the fabric deliberately."
Zoro grunted. "Doesn't matter who. We cut through them."
Sanji flicked ash. "We need supplies. Food. Fuel. Information. We can't run forever on emergency rations and dreams."
Luffy stood up so fast his chair tipped over.
"Then let's go find more rifts! More fights! More meat! More friends!"
Kai rose more slowly.
"I know where one is."
Every head turned.
Nami's eyes narrowed. "You do?"
Kai tapped his temple once—casual, almost absent-minded. "When I was falling… I saw things. Green light. A lab. A man with blue hair and a lab coat. He was running. Swearing. Opening portals. The rifts… they're connected. That one's close. And he might know more than we do."
Luffy's eyes lit up like stars.
"A guy with portals?! Awesome! Let's go get him!"
Nami groaned. "We can't just chase every glowing hole in the sky—"
But Luffy was already halfway to the door.
"Jinbe! Head for the green light! Kai says there's a portal guy!"
Jinbe's calm voice drifted back from the helm. "Course laid in."
Kai followed Luffy onto the deck.
The night sky had changed again. A new rift had torn open off the starboard bow—sickly green, flickering like bad fluorescent lighting. Through it, faint glimpses: shattered glass domes, sparking machinery, black mechs crawling over every surface, and one skinny figure in a stained lab coat sprinting across a catwalk, flipping off everything behind him.
Rick Sanchez.
Kai kept his face neutral.
Inside his mind:
[Quest Progress Update: First Companion – The Mad Scientist]
[Target location confirmed: Rift R-137 – Celestial-seized Mega-Lab]
[Time remaining: 46 hours 18 minutes]
Luffy bounced on his toes. "That's him! He looks fun! And angry!"
Kai nodded once.
"Let's go get him."
The Sunny accelerated—thrusters roaring.
Nami shouted from the helm. "Everyone to stations! We're jumping!"
Zoro drew two swords. Sanji cracked his knuckles. Usopp loaded his cannon. Franky primed the cola tanks. Brook tuned his violin to a battle key. Chopper shifted to Guard Point just in case.
Kai stayed beside Luffy at the figurehead.
No dramatic pose. No speech.
Just quiet readiness.
The green rift swallowed them whole.
Reality twisted—colors inverted, gravity stuttered, the smell of burnt copper and cheap tequila flooded the deck.
They emerged inside the lab complex.
Glass domes cracked overhead. Corridors exposed to vacuum in places. Security mechs—Celestial black and rune-etched—crawled everywhere like beetles.
And ahead, sprinting across a shattered catwalk with a half-finished Portal Gun in one hand and a rude gesture in the other:
Rick Sanchez.
"Wubba lubba dub dub! You shiny purple pricks think you can copy my tech and make it suck less?! I've seen better engineering in a Morty science fair!"
A dozen mechs opened fire—entropy lances screaming.
Luffy launched himself off the figurehead like a cannonball.
"Gomu Gomu no… Rocket!"
Kai followed—Haki hardening his legs—landing beside Rick in a crouch.
Rick spun, eyes bloodshot and brilliant.
"Who the hell are you clowns?!"
"Straw Hat Pirates," Kai said simply. "Here to get you out."
Rick burped. "Pirates. Great. Another dimension of idiots with dreams. Look, kid, I don't do rescue—"
An entropy beam lanced toward him.
Kai stepped in front—Armament-coated arm raised. The beam splashed harmlessly against the invisible black coating and dissipated into sparks.
Rick blinked.
"Okay… quiet punchy kid's got moves. Fine. Temporary alliance. But touch my gun and I turn your organs into furniture."
Kai nodded once. "Deal."
Luffy landed beside them, already inflating.
"Let's go!"
The three of them moved—chaotic, improvised, devastating.
Luffy cleared corridors with sweeping Gear-5 fists. Rick fired wild plasma shots from a wrist device he'd clearly stolen five minutes earlier. Kai stayed efficient—intercepting drones with precise Haki strikes, redirecting lances, never wasting energy.
They reached the central core chamber.
The lab's heart pulsed unstable violet. Alarms screamed: "Core overload – T-minus two minutes."
Rick skidded to a halt. "They hooked my baby to their crap. If this blows, the whole pocket dimension folds."
Kai scanned the room—Observation Haki painting weak points red.
"How long to fix?"
"Sixty seconds if you keep the toasters off me."
Kai turned to Luffy. "Cover him."
Luffy grinned. "Got it!"
Mechs poured in.
Luffy met them with Gigant fists. Kai finally allowed a controlled summon.
Palms together—seal hidden in motion—he whispered:
"Shadow Clone Technique."
Four clones appeared silently behind cover—no smoke, no sound. They moved like extensions: two flanked entrances, punching drones into walls; one pulled Rick's scattered tools into reach; one intercepted a mech aiming for Rick's back.
Rick worked frantically. "Almost… almost… you're not half bad, quiet kid. What's your deal?"
"Survivor," Kai said. "Want to keep surviving."
Rick snorted. "Fair."
A boss mech burst through the ceiling—twice the size, cannon locking on Rick.
Kai blurred forward. Haki-coated fist met chest plate. The impact rang like thunder. The mech staggered.
Luffy followed with Gigant Pistol—caving its torso.
Rick slammed the last connection home. "Done! Portal Gun v2.1—anti-Celestial shielding!"
He fired a massive green portal beneath the Sunny.
The ship dropped through—reappearing outside just as the core detonated.
Violet fire lit the green sky.
Rick stood on deck, panting, gun smoking.
He looked around—at Luffy laughing, Nami scanning, Zoro cleaning blades, the rest watching.
Rick burped.
"So. Pirate ship. Rubber idiot. Punchy kid. Bunch of weirdos. Fine. I'll stick around. But I get my own lab corner, unlimited booze, and nobody touches my stuff."
Luffy slapped him on the back—hard enough to make Rick cough.
"Welcome! You're funny and you make portals! Best crew ever!"
Kai stepped back to the railing.
Inside:
[Companion Quest: First Companion – The Mad Scientist – COMPLETE]
[Rick Sanchez loyalty initiation (Phase 1) achieved]
[Rewards: Portal Gun Schematics (Basic) integrated | Mad Science Tree Lv.1 unlocked | 2,500 System Points]
[Concealment maintained. Trust progress +18% (total: 90%)]
Rick glanced at Kai—eyes narrowing slightly.
"You're too calm, kid. Most people freak when reality folds. You just… punch."
Kai shrugged. "Seen worse."
Rick smirked. "Liar. But I like liars. They're honest about something."
He turned away—already muttering about upgrading the Sunny's engines with portal fluid.
Kai looked at the new rift forming off the bow—fiery orange this time, with the distant roar of a nine-tailed fox.
The compass in his jacket warmed.
One down.
Many more to go.
He stayed quiet.
The Age of Space Pirates was accelerating.
And Kai intended to ride every wave of it—silently, carefully, alive.
