When Luffy was stranded on this island, he met Nami who was inside the cage.
Fast forward, Nami agreed to help him as a Navigator.
Though they are on a verge of fighting Buggy Pirates, Luffy still have time to introduce Nami.
"She's Nami! She's gonna be our navigator!"
Jack tilted his head. Navigator, huh? Same like Original story. He had seen her earlier, picking pockets and dodging marine in shells town with impressive skill. But now she was sitting cross-legged inside the cage, scowling at everyone like a cat that refused to be tamed.
"You just… decided that?" Jack asked.
"Yep!" Luffy said, grinning wide.
"Did she agree?" Jack pressed.
Luffy blinked. "Yes, she agreed!"
"Really?" Jack asked.
"Yes! If I manage to help her escape from the cage," replied Luffy with a smile.
Jack waited, half-expecting the familiar ding from his system to confirm a new Straw Hat crew member.
Nothing. So he stepped forward, touched the metal bars that held Nami and turned them into sand.
"What?!" Nami gasped, wide-eyed.
"Yahoo! Nami, now that we've freed you, from now on we're nakama, you are our comrades!" Luffy cheered.
"Of course," Nami replied, trying to sound sincere, though guilt flickered in her eyes.
Jack was still waiting for the system notification but nothing came.
So she's lying, Jack thought grimly. She's just playing along until she gets what she wants. Figures. Still… it's better to let this play out naturally. Nami's the type who has to choose her own path.
He sighed and shrugged. "Captain, there's an enemy in front of us. Let's focus on that first."
"Oh, okay!" said Luffy before charging toward his first target.
Then the fight began...
Buggy's crew roared and charged, brandishing swords, clubs, and pistols.
"Get them!" Buggy shouted, his nose twitching with rage. "They dare mock the Great Buggy the Clown?!"
Zoro stepped forward, drawing two of his swords with a sharp shing.
"Finally," he muttered, a grin spreading across his face. "A real fight."
Jack glanced down at his hands. He still didn't have much combat ability. He only had 2 abilities which is illusion and matter transmutation.
So the only thing he could do right now is play dirty.
Who told system to give him Sprite ability first.
These two ability are not really suitable for combat but it still can fool enemy.
The first pirate spotted him. "Hey, there's another one over..."
Jack waved his hand activated his ability then he used the illusion.
The pirate suddenly looked like Jack himself.
"The enemy is over here!" another crewman shouted.
Before the poor man could explain, half of Buggy crew turned on him, swinging clubs.
Jack smirked and ducked into an alley, making himself invisible with a flicker of illusion. Will it work if someone knows Haki?
Maybe, he remember luffy was being fooled by vegapunk illusion.
Meanwhile, Zoro met his opponents head-on, his blades flashing in the sunlight.
"Three-sword style…" Zoro clenched the third blade between his teeth and spun into motion. "Onigiri!"
Two pirates went down in a single strike, their weapons clattering across the ground.
"You guys aren't even worth breaking a sweat," Zoro growled, stepping over their unconscious bodies.
Another group charged him from behind, but Jack illusion made them see three Zoros at once.
"Which one is real?!" one pirate shouted in panic.
"Try and find out," Zoro said with a dangerous grin before cutting them all down in a single sweeping motion.
While Zoro and Jack handled the crew, Luffy was having the time of his life.
"You call that a punch?!" Luffy laughed, dodging Buggy floating knife with a rubbery backflip.
Buggy snarled, his detached hand flying toward Luffy's neck. "Chop-Chop Claw!"
Luffy ducked just in time and grabbed Buggy's foot, spinning him like a hammer throw.
"Gomu Gomu no… Rocket!"
Buggy flew head-first into a building, bricks crumbling around him.
"Curse you, Straw Hat!" Buggy roared, his body parts reassembling. "You'll pay for messing with my beautiful face!"
Luffy tilted his head. "You have a nose, not a face."
"MY NOSE IS BEAUTIFUL!" Buggy screamed.
Jack, now hidden behind a stack of crates, was watching carefully. Luffy hasn't figured out his weakness yet, he thought. Buggy's power only works if his parts aren't restrained…
Then it hit him.
"Luffy!" Jack shouted. "Tie up his parts!"
Luffy blinked. "Ohhh! Good idea!"
Buggy froze. "Wait, what are you.... NOOO!"
Luffy grabbed Buggy floating hand and wrapped it in rope, then tied his foot to a barrel. Soon, Buggy was a squirming mess, unable to pull himself together.
"This isn't fair!" Buggy cried. "Your straw hat reminds me of someone!"
"Oh, this straw hat? It's from Shanks," Luffy said proudly.
"Shanks?" Buggy was shocked. "THAT MAN DESTROYED MY DREAM!"
Buggy then ranted about his time as a crewmate with Shanks and how that "red-haired fool" ruined his ambitions.
"Shut up! You blame someone else for your own failure and you hurt people for it!" Luffy shouted, furious.
"Gomu Gomu no… Bazooka!"
The blow sent Buggy flying high into the sky, disappearing with a twinkle of light.
The fight was finally over.
The town square grew quiet. Buggy crew was either unconscious or running for their lives.
Zoro sheathed his swords and glanced at Jack. "You're sneakier than you look."
Jack grinned. "Hey, I'll take that as a compliment. I'd rather trick an enemy into hitting each other than get stabbed myself."
Luffy landed with a thud, brushing dust off his hat. "That was fun! Where's Nami?"
As if on cue, Nami holding a small bag of treasure she'd stolen during the chaos.
"You three make quite a mess," she said with a smirk. "But I suppose I owe you for getting rid of Buggy."
"So you'll join us?" Luffy asked eagerly.
Nami hesitated, fingers tightening around the bag. "...No. I don't want to. But since you guys helped me, I'll navigate for you.... just once."
Jack said nothing, he wanted to wait for a right time to reveal about Nami situation.
She still hasn't accepted the invitation, he thought. Should I show her my ability next time?
