Chapter 24:Fishman Island!

As everyone got on the ship, they were all smiling and happy.

Zoro, walking alongside Itachi, smirked. "You've gotten bigger, more muscular."

Itachi smiled and replied, "You too." Then he noticed Zoro's eyes and asked, "What happened to your eye?"

Zoro grinned. "I got hurt while training with Mihawk."

Itachi nodded. "The strongest swordsman…"

Zoro smirked, "Yeah." But before they could continue their conversation, they both felt a sudden chill. Turning, they saw Robin standing nearby, radiating a dark aura.

Zoro quickly slipped away, while Itachi, undeterred, smiled and said, "How are you, Robin?"

Itachi looked at Robin from head to toe and said, "You've really changed." Robin blushed slightly and replied, "Yeah, I know." She glanced at herself and then asked, "Do you like it?"

Itachi smiled and said, "Yeah, you look great."

Robin smiled a little but then remembered she was still upset.

Robin looked at Itachi with anger on her face. "[I need answers."

Itachi, confused, glanced at her and replied, "Answers?" He could sense the frustration radiating from her. Saying nothing, he simply nodded. "If that's what you want, then I'll answer your questions."

Just as Robin was about to speak, a loud sound interrupted them. A cannonball was hurtling toward the ship. Usopp, wide-eyed, quickly grabbed his binoculars to get a closer look. His face turned pale as he saw the incoming threat. "Oh no! It's going to hit us!" he shouted in fear.

But before the cannonball could reach them, heart-shaped arrows flew through the air, striking the cannonball and turning it to stone. It shattered harmlessly in midair. Everyone watched as the Kuja ship slowly approached, positioned between them and the Marine vessel.

Robin looked at the approaching ship with a hint of irritation. "Kuja ship..." she muttered, then glared at Itachi. Nami, noticing the tension, asked, "Kuja?"

With an eerie smile, Robin replied, "Itachi, would you like to explain?"

Nami's face turned pale. Itachi, still confused but understanding the situation, sighed. "They are the Amazonian pirates, led by the Empress, a Warlord of the Sea... Boa Hancock," he said with a slight smile.

Robin's smile grew more sinister as her anger flared. "And why, exactly, are you smiling?" she asked through gritted teeth.

Itachi, still oblivious, calmly answered, "She's like family to me."

Robin's eyes widened as she began to imagine the worst—Hancock and Itachi starting a family together. Nami also froze in shock upon hearing this. Without warning, she hit Itachi in the gut.

Itachi, shocked, exclaimed, "Why did you do that?"

Robin, with a sad expression, whispered, "So it's true... anyone who sees her will be attracted to her beauty..."

Itachi, still confused, added, "And... they turn to stone in the end."

Brook, looking through binoculars, said, "Oh, too bright! She's dazzling!" and fainted dramatically. Usopp took a glance as well and shouted, "Wow, she must be a goddess!"

Sanji, now wide awake, jumped up. "Goddess? Goddess? I need to see her!" He snatched the binoculars from Usopp and looked at Hancock, only to immediately turn to stone with heart-shaped eyes.

Itachi sighed, muttering, "How childish." Zoro, beside him, nodded in agreement. Robin, glaring at him, thought, Just you wait...

Luffy, carefree as always, walked forward and said, "Oh, it's Hancock! She must be helping us!" Itachi smiled at the mention of her, which only further irritated Robin. The tension in the air grew heavier as Nami and the others could feel the chilling aura radiating from Robin.

On the Kuja ship, Hancock spotted the Thousand Sunny. "Go, Luffy... now is the chance!" she thought to herself, and winked at the ship.

Brook, witnessing the wink, fainted again with heart-shaped eyes. "She winked at me!" he said before collapsing.

Itachi looked at the ship and remarked, "It looks like jelly."

Robin, slightly irritated, explained, "This is the coating that will help us go underwater."

Itachi, unsure why she seemed so annoyed, glanced over at the Kuja ship and smiled. Robin, on the other hand, was waiting for the right moment.

Just then, Franky climbed down and activated the wind supply, causing the jelly-like coating to inflate like a balloon. Itachi looked around, intrigued. "That's interesting," he commented.

Robin muttered under her breath, "I'll remove your interest in a minute, just you wait…"

Itachi glanced at her, confused. Why is she upset? I haven't said anything to her… Is that why?

At that moment, they both heard Luffy's voice shout, "Let's set sail! I have a lot of things I want to share with you! But in any case, thank you for going along with my selfish decision for two years!"

Everyone smiled at him as the ship began its journey, submerging into the sea.

Everyone looked around in awe. Robin glanced up and said, "The surface is already far above us."

Itachi, gazing at the view, commented, "What a sight…"

Franky chimed in from behind, "Submarines can't have windows this wide."

Chopper, with a worried expression, muttered, "We're sinking… and sinking…"

Nami looked up and added, "It feels like we're leaving the inhabited world behind… It makes me nervous."

Usopp stammered, "C-c-can we go back to the surface? Not that I'm scared or anything…"

Luffy, wide-eyed and beaming, said, "It's so beautiful down here!"

Brook pointed out, "Look here, everyone!"

All eyes turned to the mangrove roots, and Sanji remarked, "Oh yeah, come to think of it, the Sabaody Archipelago is made up of giant mangroves."

Brook, overwhelmed by the scenery, exclaimed, "I'm in awe of nature's beauty! My eyes could pop out… wait, I don't have eyes! Yohohohoho!"

Zoro, unfazed, said, "I've seen this before."

Sanji, irritated, snapped, "Yeah, because you got on the wrong ship back then!"

Itachi, looking down at the roots, mused, "I can't believe these roots run all the way down to the sea…"

Robin nodded, "I was thinking the same thing."

Itachi smiled and said, "Sometimes our thoughts match."

Hearing this, Robin blushed slightly but quickly grew irritated, saying nothing.

Itachi, sensing the tension, asked, "Ah, Robin, didn't you want to ask me something?"

Everyone around them flinched, taken by surprise. Sanji, clueless about the situation, angrily shouted, "Robin-chan doesn't want to talk to you!"

Ignoring him, Itachi continued calmly, "You can ask anything. I'll try my best to answer."

Robin glanced at him, her tone serious. "What's your relationship with Hancock?"

The entire crew tensed at her eerie voice, but they were all eager to hear his answer. Sanji, upon hearing the question, fell to his knees in despair and began to cry. "Itachi, you bastard… stealing all the women from me…"

Itachi sighed and asked, "Is that why you're angry?"

Robin snapped, "Just answer me already."

As Luffy was about to say something, Nami, Usopp, and Zoro quickly grabbed him and covered his mouth. Nami hissed, "Don't butt in, you idiot, or you'll make the situation worse!"

Itachi smiled and said, "She's like my sister."

Robin looked at him in surprise. "She's your sister?"

Itachi nodded, confirming it. Sanji, hearing this, immediately perked up, exclaiming, "Ah, I still have a chance!" The rest of the crew sighed in relief.

Luffy, looking slightly annoyed, added, "I was going to say that too. I know she's his sister."

Nami frowned. "Then why didn't you say anything?"

Luffy shrugged. "I was going to, but you guys stopped me!"

Zoro, Usopp, and Nami sweatdropped at his response.

Suddenly, Luffy remembered something, his face lighting up. "Oh, Robin! I have a message for you from Hancock."

Robin turned to him, curious. "What is it?"

Itachi, also curious, silently hoped, Please, let it not be something weird…

Luffy put on his thinking face and said, "Ah, she told me to tell you that Itachi is really good in bed and can last for an hour without breaking a sweat, which makes Hancock very satisfied.I don't know what that means but yeah…."

Hearing Luffy's words, everyone's eyes widened in shock. Robin stood frozen, her expression was filled with anger. Itachi was equally surprised. Nami, stunned, stammered, "Itachi… you…?"

Zoro muttered, "Things just went sideways real fast..."

Usopp, Chopper, and Franky, now fearing Robin's wrath, stepped back, while Brook chimed in, "What was her panties' color?"

Sanji, completely heartbroken, cried out, "He stepped on my dreams again!"

Robin looked very angry, and glanced at Itachi, noticing that he seemed just as surprised. Itachi, feeling the weight of everyone's stares, turned to Robin. "That's not true… believe me," he said, his voice steady but pleading.

Robin, her anger rising, retorted, "One hour, Itachi?"

Itachi, maintaining his composure, replied, "Do you not believe me? I'm telling you the truth."

Robin folded her arms and said, "And why should I believe you?"

Itachi sighed and replied, "I can show you my memories if you want."

Robin narrowed her eyes. "How do I know they aren't altered?"

Itachi sighed again, his tone calm but firm. "I've already told you, she was like a sister to me. I serve no one but the truth, and I would never do something like that."

Robin, her frustration cooling slightly, took a deep breath and said, "Fine, I believe you this time."

Itachi nodded, relieved. He then turned to the others. "I want all of you to believe me. That wasn't true."

Nami, rolling her eyes, sighed. "Yeah, yeah, we believe you. You're not that kind of person."

Zoro nodded in agreement but added, "Though I know one person who still doesn't." He turned to Sanji, who was still on the floor, crying bitterly.

Usopp sighed in relief while Franky said, "That's good." Brook, unfazed, continued, "I still want to know about her panties' color though."

Itachi sighed deeply, visibly tired of the situation. "You should just ask her yourself if you're that curious."

At that moment, Robin's attention shifted. She noticed a letter peeking out of Itachi's pocket. With a quick motion, she snatched it. Itachi, seeing her take the letter, sighed and thought, Here we go again...

Robin, holding the letter, asked, "What is this?"

Itachi, glancing at the letter, answered, "It's from Amazon Lily. A girl named Aphelandra gave it to me… it's another confession letter."

The entire crew once again widened their eyes in disbelief. Usopp, exasperated, said, "Again?! We get it—you're a handsome guy!"

Itachi nodded politely. "Thank you."

Nami, crossing her arms, asked, "Then why did you keep it?"

With a sad smile, Itachi replied, "When I read it… I felt sympathy. I kept it out of respect."

Robin, her eyes narrowing, stared at him before opening the letter. As she read it silently, her expression shifted, a mixture of curiosity, frustration, and something else swirling within her.

Alephandra's Letter to Itachi

To the one who forever changed my heart,

When I first saw you, I thought you were one of us—another woman on this island full of warriors. It wasn't until later that I realized the truth: you're not only a man but perhaps the most beautiful and mysterious man I have ever seen. Your strength, your quiet nature, and that deep sadness in your eyes—I couldn't look away.

I understand you have to leave, that your path is one of duty, not of choice. And I know, deep in my heart, we may never meet again. I've accepted that, but it doesn't make it any easier. I have never felt like this before, and I don't think I ever will again. If I hadn't met you, perhaps it would have been better for me. I wouldn't be left with this feeling of emptiness, this ache that I carry knowing I will never see you again. But meeting you, even briefly, has filled my heart in ways I didn't know were possible.

I hope you can find your friends, that they bring you joy and peace. And if you ever find someone who can fill that void in your heart, please take care of them as you would take care of yourself. But… if you don't, if your heart remains as distant and unreachable as I fear, know that I will still wait for you.

Even if the days grow long and years pass, I will always remember you. You've left a mark on me, Itachi, and I will carry it until the end.

Please take care of yourself, wherever you go. I hope that in the world beyond this island, you find what you're looking for.

With all my love and a heart that will forever belong to you,

Alephandra

Robin couldn't help but feel sad while reading the letter. Itachi noticed her expression and quietly said, "I know how you feel. She was a very kind woman."

Robin nodded and handed the letter back to him. "Let's just say I forgive you," she replied softly.

Itachi looked at her with a gentle smile. "Thank you."

Everyone smiled, and Luffy, always full of energy, exclaimed, "Look at the Fish!" He jumped into the bubble and added, "I want to eat it!"

Zoro, seeing the bubbles, pulled out his sword and said, "Let's cut them and eat!"

Chopper and Usopp immediately smacked them on the head. "Those bubbles will burst, you idiots!" Ussop scolded.

Itachi sighed. "They never change," he muttered.

Robin, now feeling more at ease, giggled. Itachi then commented, "These bubbles are very similar to the ones at Sabaody."

Robin smiled and nodded. "That's right. They're made from the same material. You and nami are right—they stretch to a certain point, and beyond that, they allow things to pass through."

Itachi nodded, impressed. "That's quite handy."

Robin blushed slightly as she glanced at him. Just then, Itachi pointed ahead. "Look at the whale."

Everyone turned to see a massive white whale swimming beneath them. Luffy's eyes widened with excitement. "Whoa! It looks like a big old man—like Whitebeard!"

Itachi observed the surroundings. "It's getting darker."

Zoro nodded. "Yeah, it is."

Franky checked the readings on the ship. "I think we're about 1,000 meters deep."

Robin added, "Even though we're descending, it feels like we're flying through the sky."

Nami agreed. "I feel the same way. It's similar to how it felt on Weatheria when I was there for two years."

As they all marveled at the underwater view, Usopp suddenly froze, his eyes wide. "Look! There's a ship coming toward us!"

As the Straw Hat Pirates cruise through the open sea, a strange ship appears on the horizon. The crew gathers on the deck, staring at the approaching vessel with curiosity.

Luffy, with his usual grin, tilts his head. "Whose ship is that?"

Nami narrows her eyes, recognizing the large creature pulling the ship. "Wait... that's Momoo! The pet sea cow from Arlong's crew!"

Sanji's eyebrow twitches, lighting a cigarette. "Oh yeah... I remember that dumb sea cow. He got a pretty good taste of my boot last time."

Luffy laughs, clenching his fist. "Heh, I punched him too! Looks like he remembers us!"

Itachi, standing calmly beside Robin, glances over at the approaching ship with his usual stoic expression. His Sharingan activates briefly, observing the ship's movements. "Momoo is retreating. He recognized you."

Sure enough, Momoo, seeing Nami, Sanji, and Luffy, lets out a terrified bellow. With a panicked flip of his fins, he swims back in the opposite direction, towing the ship away at high speed. However, before the ship can completely vanish, a lone figure manages to leap aboard the Thousand Sunny.

Caribou, the swamp-man pirate, lands on the deck with an evil grin. "All right, men! Let's—" He turns around, noticing that his crew is nowhere to be seen. His grin falters. "Wait… where's everyone?"

Franky cracks his knuckles and picks Caribou up with one hand, effortlessly lifting him off the ground. "You mean those guys you left behind? Looks like it's just you now, swamp boy."

Caribou's confidence drains instantly. "N-no, no! I swear, I'm not their captain! I'm just a human bullet for them! I don't even like those guys!" He waves his hands frantically. "Please don't throw me overboard!"

Franky narrows his eyes. "You should've thought of that before jumping onto our ship."

With a casual motion, Franky tosses Caribou against one of the side rails. Caribou hits the railing with a thud, groaning in pain. "I-I don't want to go back! Let me ride with you guys for a bit!"

Zoro, leaning against the mast with his swords at his side, raises an eyebrow. "This guy's annoying. Should we even let him stay?"

Robin, standing nearby, glances at Itachi, who is quietly watching the scene with his usual calm demeanor. She finds herself stealing glances at him more often lately, her heart skipping a beat whenever their eyes meet. He's always so composed...

Meanwhile, Franky throws Caribou against the side rails with ease, though not too hard. "Alright, you can ride with us for a while," he says, wrapping Caribou in ropes, "but don't try anything funny, or I'll let Itachi deal with you."

At the mention of Itachi's name, Caribou pales. "D-Demon Eye Itachi?! That Itachi Uchiha?" Caribou stammers, his voice shaking.

Itachi steps forward, his presence alone enough to make Caribou freeze in fear. "If you cause any trouble, you'll wish Franky had thrown you into the ocean," Itachi says, his voice low and calm but filled with unmistakable menace. His Sharingan briefly flickers in his eyes, causing Caribou to whimper and back away further.

Luffy laughs, not fully grasping the terror Itachi inspires. "You can ride with us, but if you mess with my crew, you'll have to deal with him and me!" Luffy warns with his usual carefree tone.

Zoro, leaning against the mast with his arms crossed, smirks. "It's not just Luffy you should be worried about," he adds. "Itachi's got a way of dealing with trash like you."

Caribou frantically nods, feeling the weight of both Luffy and Itachi's reputations looming over him. He doesn't dare speak another word out of line, knowing that one wrong move could be his last.

The Straw Hats had just finished securing Caribou on the Thousand Sunny's deck, though they were unaware he was secretly plotting his escape. Bound in ropes, Caribou silently smirked to himself, thinking, These fools. They have no idea I can slip out of these ropes any time I want. But there's no way I can take them all on at once. I'll bide my time, learn their weaknesses, and then… I'll kill them one by one.

Itachi looked at Caribou with a piercing gaze, his Sharingan glowing faintly. "What are you thinking?" Itachi asked calmly.

Caribou flinched in fear, feeling as though Itachi's eyes were staring straight into his soul. He frantically shook his head, trembling, and stammered, "N-nothing!"

Luffy stood by the railing, looking at the horizon with excitement. "Hey, Nami! Wouldn't it be faster if we just go in a straight line?"

Nami, standing next to him with a hand on her hip, sighed in frustration. "Luffy, if we did that, we'd be swallowed up by the currents. Not to mention we could hit a volcano or sea mountain before even finishing our descent. There's only one safe route down."

At this, everyone perked up. Robin raised an eyebrow. "A descent, Nami? How deep are we going?"

Nami nodded. "The deep sea. And it's going to get colder the further down we go." She gestured to the crew. "Everyone, put on a coat. The water in the deep sea is freezing."

Brook, listening attentively, chimed in with his usual calm demeanor. "Ah, yes, the deeper levels of the sea have what are called Deep Currents. These are large, powerful ocean streams that move completely differently from surface currents. From what I've heard, once you're down in those Deep Currents, you can't just swim back up easily. Some say it can take nearly 2,000 years to return to the surface!"

Franky, standing at the bow of the ship, cupped his hands around his mouth and called out, "Hey, Nami! You might want to come look at this! 'It' has come into view!"

The crew quickly made their way to the front of the ship. Luffy bounced with excitement. "What does the current look like, Franky?"

As they approached the edge of the ship, Franky, wide-eyed with awe, gestured toward the phenomenon in front of them. "This, Straw Hats… is what I call Mother Nature's masterpiece. The Great Downward Plume."

Itachi glanced downward at the spiraling plume and remarked, "It feels like it's pulling us down."

Robin, observing the swirling vortex below, nodded. "Yes, look at the spiral. It's beautiful... though, if we get caught in it, the boat—and us—would be sliced to pieces."

Usopp, panicking, shouted, "Robin, don't say such dark stuff!"

Everyone gasped in awe as they looked out at the giant plume—a towering, swirling column of water that spiraled downward into the depths of the ocean. It was like a waterfall in reverse, pulling everything down with it. The currents twisted and churned, creating a mesmerizing yet terrifying sight.

Zoro, leaning on his sword, grinned. "Now that is something you don't see every day."

Itachi nodded said yeah you are right

Nami adjusted her hat, her eyes fixed on the plume. "We need to ride that current down. If we don't, we'll get stuck in the surface currents and never reach the deep sea."

As everyone marveled at the sight, Caribou, who had been unusually quiet, suddenly stood up, his eyes wide with panic. "You idiots! Turn back now! Something's wrong with that current!"

The crew turned to face him. Luffy blinked, tilting his head. "Huh? What do you mean?"

Caribou, trembling slightly, his usual arrogance replaced with genuine fear, shook his head. "I've heard stories about the Downward Plume. Ships that go in don't come back out. You're all walking into a death trap!"

Sanji flicked his cigarette, narrowing his eyes at Caribou. "And why should we believe anything you say? You've been trying to kill us since the moment you got here."

Itachi, standing near the back, had been observing Caribou closely the entire time. His Sharingan glowed faintly as he stepped forward. "He's afraid. But whether it's out of concern for himself or us, that remains to be seen." Itachi's voice was calm and calculating, cutting through the tension.

Caribou's eyes widened as he met Itachi's gaze, the cold red eyes of the Uchiha making him tremble. "I-I'm telling the truth! That current will pull you down so fast, you won't be able to steer! We'll all drown!"

Robin placed a hand on her chin, thoughtful. "There may be some truth to his words. The Downward Plume is a powerful force of nature."

Franky, ever the optimist, crossed his arms confidently. "I built this ship to withstand anything, even the strongest of currents. As long as we steer carefully, we'll be fine."

Nami nodded. "Franky's right. If we stay on course and time it right, we can ride the current safely. We just need to make sure we don't get pulled in too fast."

Luffy grinned, clenching his fist. "Alright! We've come this far. Let's go down!"

Despite Caribou's warnings, the Straw Hats had made up their minds. The Thousand Sunny turned toward the Great Downward Plume, ready to descend into the unknown depths of the ocean.

Itachi stood silently at the side of the ship, his eyes fixed on the swirling water below. As he narrowed his gaze, something caught his attention.

"Robin," he asked, still staring down into the depths. "Can you see anything down there?"

Robin looked over, peering into the darkness. "It's very dark... so, no," she replied.

Itachi's voice lowered. "I think there are tentacles down there."

As the Thousand Sunny approached the monstrous creature lurking at the bottom of the Downward Plume, Luffy squinted, pointing down toward the dark abyss. "Hey! I see something down there... It looks like a monster!"

The crew gathered at the railing, peering into the deep waters. Caribou, still bound and standing to the side, shook his head. "A monster in a downward plume? Never heard of such a thing. You're all imagining things!"

Itachi said just as I said its had tentaicles so it's a octopus…robin nodded said its large foe it size

Franky adjusted his goggles, his eyes locked on the creature below. "Oh, that's no imagination, Caribou and Itachi you are right. That's a Kraken. A giant, mythological octopus. I've heard it can crush ships in a single blow!" He folded his arms with a serious look. "Looks like it's been staying down there, feeding on the ships that tried to pass through here over the last few days."

Nami grimaced, gripping the railing. "That's why the currents have been so chaotic lately."

Luffy, however, looked far from concerned. Instead, his eyes lit up with excitement. "A Kraken, huh? I'm gonna tame it!"

"You're going to what?!" Usopp shouted, his face turning pale. "Luffy, this is insane! You can't tame that thing!"

Itachi just sign at his remark said why am I not suprice…robin just look at them with a smile 

As Luffy eagerly prepared to jump overboard, Caribou's attention shifted when he saw a familiar sight in the distance—his own ship, with Coribou and the rest of his crew, including Momoo, speeding toward them. "Finally!" Caribou exclaimed, relieved. "They're coming to save me!"

However, before Caribou's crew could get close to the Sunny, a massive tentacle from the Kraken shot out from the depths, wrapping around their ship. The coating bubble surrounding it popped with a thunderous burst, and the Kraken effortlessly crushed the vessel with one swift motion. Caribou watched in horror as his crew's ship disintegrated, and his crew, including his brother Coribou and Momoo, sank below the waves.

"N-No!" Caribou shouted, his face pale with shock. "They're… they're gone!" He sank to his knees, his voice trembling. "I can't believe it… My crew…"

The Kraken, now turning its sights on the Sunny, let out a deep, rumbling sound as it prepared to strike. Its massive tentacles loomed overhead, ready to crush the Thousand Sunny.

"Here it comes!" Zoro called out, unsheathing his swords.

Luffy clenched his fists, his excitement building. "I've got this!"

However, Usopp quickly intervened, waving his hands frantically. "Wait! You can't just attack it like that! If you break the coating bubble, we're all gonna drown down here!"

Itachi said with is sword ready said I was eagar to use my sword…

Franky, thinking fast, rushed to the helm. "Leave it to me!" He activated the ship's emergency system. "Chicken Voyage, engage!" The Sunny shot forward in a sudden burst of speed, narrowly dodging the Kraken's tentacles.

Luffy, still determined to fight, crossed his arms. "We've got to take it out! I'm not leaving here without taming that Kraken!"

Caribou, realizing Luffy's resolve, saw an opportunity. "If you're so set on fighting, I've got a suggestion," he said slyly. "You can't fight on the ship without damaging the coating, but you can fight out there. I'll show you how."

Luffy, Zoro, and Sanji turned to him, intrigued but wary.

Caribou continued, "I call it Barefoot Coating. It's like a man-made diving suit. You'll be in your own personal coating bubble, and you won't damage the ship. Just tie yourself to a rope lifeline so you can find your way back."

Usopp, wide-eyed, shook his head in protest. "That sounds risky! How do we know it'll work?"

Caribou smirked. "What sounds better to you—fighting on the ship and drowning when the bubble bursts, or fighting out there where you've got space to take the Kraken down?"

Usopp gulped, realizing the truth of Caribou's words. "Fine… fine! I'll take that over drowning."

Itachi glanced at Zoro and said calmly, "I'll come with you."

Zoro, folding his arms, shook his head slightly. "Wait here. We need someone to watch the ship, in case he tries something stupid," he said, casting a suspicious glance at Caribou, who flinched under the gaze.

Itachi gave a small nod, understanding Zoro's reasoning. "Alright, just stay safe."

Luffy, grinning as always, chimed in, "Alright! If that's settled, let's get going!"

Luffy, Zoro, and Sanji—readied themselves, slipping into the coating bubbles provided by Caribou. Once inside, they tied themselves to lifelines, though all three soon discarded them.

"These ropes are just gonna get in our way," Zoro said, slicing his lifeline with one swift motion. Luffy and Sanji quickly followed suit.

"Alright, let's do this!" Luffy declared.

The Kraken roared, attacking again with its enormous tentacles. From the Sunny, Franky fired rockets from his shoulders, blasting one tentacle away before it could hit the ship. As another tentacle swung toward them, Chopper transformed, using his Rumble Ball to enter Guard Point, his fur expanding into a massive shield that protected the Sunny from the Kraken's blow.

The force of the impact sent the Sunny hurtling backward toward a massive undersea mountain. Nami and Usopp screamed as they braced for impact, but just before the ship could crash, Robin extended two enormous hands made from her Hana Hana no Mi ability, pushing the ship away from the mountain and back on course.

Itachi noticed Robin struggling to maintain her strength in the sea, her usual composure faltering. Gently, he approached her, his voice calm and reassuring.

"You did great, Robin. Now leave the rest to me," he said softly, his Sharingan glinting with determination.

Robin blushed slightly, caught off guard by his kind words. She gave a small nod, her cheeks warm as she smiled. "Alright," she whispered, trusting him completely.

Luffy, Zoro, and Sanji, now floating in their coating bubbles, charged at the Kraken, ready for the fight of their lives. The stage was set for an epic battle in the depths of the ocean, and the Straw Hats were determined to come out on top.

The intense battle with the Kraken was unfolding underwater, and Luffy, already in Gear 3, hardened his arm with Armament Haki. "Gomu Gomu no Elephant Gun!" Luffy shouted, launching his attack. But as he was using it in the ocean, he began to weaken. The seawater was taking its toll on him.

The Kraken, sensing his vulnerability, tried to grab him with one of its massive tentacles. Before it could, though, Sanji darted through the water, using his Blue Walk technique to speed outside his bubble. "I'll handle this!" Sanji declared, his leg igniting with fiery power. "Diable Jambe: Bien Cuit: Grill Shot!" His powerful kick slammed into the Kraken, leaving a scorching mark on the creature.

Not to be outdone, Zoro rushed forward, spinning his swords. "Santoryu Ogi: Rokudo no Tsuji!" Zoro slashed through one of the Kraken's tentacles, cutting it cleanly into six pieces.

Itachi looked at them with a smile and said, "They also got strong."

"Oi! You two are going to chop off all its legs before I get a chance!" Luffy complained, charging back in.

Ussop angry said," that's not the time you idiot..!"

With a final punch, he launched his attack. "Gomu Gomu no Elephant Gun!" His fist collided with the Kraken, sending shockwaves through the water. The Kraken, beaten, fell limp.

As the trio looked around, they suddenly noticed a large shark wearing a shirt swimming around the Kraken. Luffy's eyes widened in curiosity. "Huh? Is that a shark... with a shirt?" But before they could even process it, a powerful current from the Downward Plume swept them all away.

Itachi's gaze fixed on the shark swimming nearby. "Shark…" he muttered under his breath, a flicker of memory flashing through his mind. He couldn't help but recall Kisame, his former comrade.

Robin, standing beside him, noticed the change in his expression and looked at him with concern. "Itachi, is something wrong?" she asked gently.

Shaking his head, Itachi replied, "No, it's nothing. Just... remembering someone, that's all."

Before he could say more, a sudden and powerful force began pulling the ship, interrupting the moment. The crew braced themselves, feeling the intense drag as the sea threatened to consume them.

"Ahhhh! We're getting pulled in!" Luffy yelled as he, Zoro, and Sanji were dragged further down into the depths of the ocean.

Back on the Thousand Sunny, Nami frantically navigated the ship. "Franky, steer clear of those rocks!"

"I got it!" Franky replied, gripping the helm as they narrowly avoided crashing into the sea floor.

However, the rest of the crew aboard the Sunny was now lost in a dark and cold part of the ocean. Brook shivered. "It's so cold down here, I can feel it in my bones... even though I don't have any flesh! Yohohoho!"

As they turned on some lights, they were immediately met with the terrifying sight of massive sea monsters swimming around them. Usopp's face went pale. "Wh-what are those?!"

"They're... sea monsters," Nami whispered, her voice trembling. The creatures were larger and more terrifying than anything they had ever seen.

A caption flashed before them, describing the dangerous depths they were in: "The Deep Sea, where light cannot reach. No normal creature exists here. It is known as 'The Underworld of the Sea'."

Meanwhile, Brook had been scanning the ship, his eyes suddenly narrowing. "Wait... Caribou! He's not tied up anymore!"

Nami gasped, looking around in panic. "What?! Where did he go?"

Itachi's Sharingan scanned the dark waters, locking onto the distant movements. "He's right here," Itachi said calmly, pointing to a shadow moving in the depths. "Now, let's grab him and tie him in the barrel."

The crew looked relieved. "That's a relief," Usopp muttered.

Robin, always cautious, glanced at Itachi. "We need to stay on our guard," she said.

Itachi nodded. "Agreed. First, we need to find Luffy and the others."

Nami frowned, looking worried. "We got separated. I can't find Luffy, Zoro, or Sanji…"

Itachi's expression remained stoic. "I know. We need to locate them fast."

Robin, her voice slightly grim, added, "I just hope they haven't been shredded by whatever monster is lurking down here."

Usopp, horrified, responded, "Your imagination is terrifying, Robin!"

As the crew discussed the situation, Itachi looked around. "There are a bunch of sea monsters," he said calmly.

Chopper, terrified, stammered, "It's too dark…"

Brook, equally unnerved, added, "I'm not good with darkness either, and I can feel them too!"

Franky adjusted his glasses. "We're about 7,000 meters deep now. Even a shark shouldn't be able to survive at this pressure."

Chopper nodded. "Are we near Fish-Man Island?"

Itachi glanced at the depth gauge. "Maybe. They could've reached it already."

Robin shook her head. "Camie said Fish-Man Island is 10,000 meters below sea level. We still have another 3,000 meters to go."

Usopp, clearly worried, chimed in, "They only have a small bubble! Even if they're alive, there might not be enough air. It's dangerous!"

Nami sighed in frustration. "That's why I told them to attach the safety ropes!"

Itachi, remaining calm as ever, said, "Standing around won't help. We need to search. Keep the ship steady while I look."

Franky, puffing out his chest, declared, "No need! I've got this covered!" He adjusted his sunglasses dramatically.

Chopper, with stars in his eyes, asked, "Is it from your eyes, Franky? Do you have some super tool?"

Even Itachi was curious for a moment, looking at Franky with mild anticipation.

Franky grinned. "Behold… FRANKY NIPPLE LIGHT!"

Usopp's face twisted in anger. "WHY DOES IT HAVE TO BE THERE!?"

Itachi sweatdropped and sighed. "I should've known…"

Suddenly, Robin looked up, eyes narrowing. "Itachi, you were right. There's something massive above us."

The crew's attention snapped upward. Usopp gulped, "That's huge…"

Chopper, trembling, added, "It's terrifying…"

Nami, on the verge of tears, muttered, "No way…"

Franky slammed the controls, pushing the ship into full speed. "We've got no time. We need to find them fast!"

The Thousand Sunny sped through the dark ocean, dodging the massive sea monsters, as Franky focused on getting them closer to their lost crewmates.

Chopper, Usopp, Brook, and Nami scanned the area with binoculars, while Itachi and Robin observed their surroundings, Itachi using his Sharingan to search. Robin glanced at Itachi's eyes and noticed something. "You use your three-tomoe Sharingan more than your Mangekyo," she remarked, her curiosity piqued.

Itachi smiled slightly, surprised by her observation. "Yeah, that's to control my Haki better."

Robin raised an eyebrow. "You mean Conqueror's Haki?"

Itachi nodded. "If I use Haki with the Eternal Mangekyo, it amplifies the impact… even just opening my Mangekyo could cause damage to the surroundings." He paused, glancing at Usopp, Chopper, and Nami. "It's safer this way."

Robin nodded in understanding. "I see… makes sense."

As they continued discussing, Chopper suddenly pointed upward. "Oh, look! A massive jellyfish!"

Brook's skeletal face twisted in awe. "That's huge!"

Itachi studied it for a moment and said, "It does look beautiful."

Robin agreed. "Yes, but be careful…"

Just then, one of the jellyfish's tentacles slid toward the ship, and Chopper reached out to touch it.

"Don't!" both Itachi and Robin shouted at once.

Chopper froze, looking back in confusion. "Why?"

Robin quickly explained, "They're venomous!"

Chopper yelped and hurriedly backed away, just as the giant tentacle slid away. From behind, they heard the sound of something approaching—a massive ship.

Franky shouted from the helm, "I have to move the ship! We're in trouble!"

Before Franky could take action, Itachi stepped forward. "Wait." He moved to the edge of the ship, gathering chakra in his hand. "Rasengan!" He thrust his hand forward, and the powerful blue sphere pushed the ship forward at great speed, narrowly dodging the looming jellyfish.

The crew stared in awe, wide-eyed. "Wow… what was that?" Usopp asked, his voice full of amazement.

Itachi looked back at them calmly. "That's called Rasengan. It's a powerful jutsu."

Robin, intrigued, asked, "Did you create it?"

Itachi shook his head. "No, someone from my world was able to use it. I just copied it."

Chopper, Usopp, and Nami looked at Itachi with stars in their eyes. "That was so cool!" they exclaimed in unison.

Itachi smiled softly. "Thank you."

Robin observed the impact of the Rasengan. "It's connected to wind, isn't it?"

Itachi nodded. "Yeah, it's a wind-based jutsu. Very powerful."

Robin admired the glowing blue sphere. "It's beautiful…"

Itachi chuckled softly. "You're right."

Robin blushed as she watched him, her heart beating faster. He's grown so much stronger, she thought to herself. I… I want to confess my feelings, but… it's hard…

Chopper said, "Do you guys feel hot here?" Itachi nodded. "It certainly does."

Franky frowned. "Why's there so much smoke? It's blocking our view forward."

Itachi, calm as ever, replied, "It's a volcano."

Nami, frustrated, asked, "Why are you so calm? We need to move!"

Chopper, looking down, said nervously, "Something's coming upward!"

Usopp, panicking, screamed, "It's a carnivorous tubeworm!"

Itachi immediately stepped back and used his Rasengan to push the ship forward. His eyes widened as he spotted something. "Look! A giant crab!"

Franky helped Itachi, shouting, "A little Coup de Burst!" and launched the ship forward. Brook and the others shouted again as they saw more strange creatures. Brook exclaimed, "I don't even know what these things are!"

Itachi, once more using the Rasengan, sighed as Chopper yelled, "The deep sea is terrifying!" Sweatdropping, Itachi thought to himself, How am I using this jutsu? If the Fourth Hokage saw me now, he might get angry...

As they moved forward, Chopper noticed a bright light. Smiling, he asked, "Is this from Luffy and the others?"

Itachi, scanning the area, shook his head. "I don't think so..."

Robin added, "I think it's something else..."

Suddenly, Franky, wide-eyed, said, "It's a trick!"

Usopp and Chopper, both trembling in fear, said, "The deep sea is terrifying!"

Itachi turned to Nami. "Give me the coating immediately."

Nami hesitated, and Robin interjected, "What if you get lost like them? That's not a good idea."

Itachi, determined, said, "Robin, we have to do something." He looked at Nami. "Please, give me the coating."

Reluctantly, Nami nodded, and Itachi put on the bubble suit. Robin tied a rope around him and said, "For your safety."

Itachi nodded in acknowledgment and jumped outside, activating his EMS, which emitted a faint burst of Haki. The sea creatures around him froze in fear, and even the fish they were pursuing halted.

Suddenly, Itachi noticed a massive monster beside them. Usopp shouted, "Itachi, come back!"

But instead of attacking the ship, the monster struck the fish monster. Much to their surprise, it said, "I told you not to eat ships. Captain Vander Decken won't like this."

Itachi, observing the situation, deactivated his EMS. Nami asked in disbelief, "Did that thing just help us?"

Robin called out urgently, "Itachi, come inside fast!"

Itachi turned, scanning his surroundings. "Wait." He looked directly at the monster and asked, "Hey, you… what are you?"

Usopp's eyes widened as he stared at the enormous figure. "It's an Umibozu! A sea giant!" he cried, trembling.

"That's no Umibozu," Robin corrected calmly. "It's just a regular giant."

Itachi hearing this lookat him and he hand on the sword ready to attack

The crew watched as the giant, whose name was Wadatsumi ,dealt with the angler fish. Meanwhile, Brook, standing on the deck, suddenly stiffened. His skeletal face grew serious. "Wait... Do you hear that?"

Everyone went silent for a moment, and then they heard it—an eerie song echoing across the water.

"That sound..." Brook muttered, his eyes widening in recognition. "No... it can't be..."

From behind Wadatsumi, an old, ghostly ship emerged from the darkness. Its tattered sails billowed in the deep sea current as it floated ominously toward them.

Brook's voice trembled as he spoke. "That ship... It's the Flying Dutchman."

Nami blinked. "The Flying Dutchman? You mean the legendary ghost ship?"

Brook nodded solemnly. "Yes. It's known as 'the ship that should not be.' The story dates back hundreds of years. On a stormy day, a captain named Vander Decken went mad. He threw his crew overboard one by one, killing them all. For his crimes, he was cursed to wander the seas for eternity, forbidden to ever reach port."

The crew stared in awe and horror at the approaching ship. "That's the cursed ship of Vander Decken," Brook continued. "And now it's here, right in front of us."

Itachi sighed, noticing Robin calmly sitting nearby, sketching a picture of the ship. He sweatdropped, thinking, Everyone's terrified, and she's... drawing.

Usopp's knees shook as he gripped his slingshot. "W-wait a minute, you're saying that's... the ship of a cursed madman?!" His voice wavered, pure panic taking over.

As the ship drew closer, Wadatsumi called out to the angler fish, Ankoro, "If you eat that ship, we won't get any treasure!"

The Straw Hat crew stood frozen in place, watching as the Flying Dutchman loomed ever closer, its eerie presence sending chills through their spines.

Adatsumi shouted, "Right, captain!" and was about to throw a punch when Itachi swiftly drew his sword and sliced off the monster's hand. In a cold voice, Itachi said, "Keep your hands away..." Wadatsumi froze, terrified by Itachi's presence. Suddenly, one of the Kraken's tentacles struck Wadatsumi, forcing him to step back as the Kraken reluctantly attacked him.

Amidst the chaos, a voice called out, "Alright, that's enough!" Everyone turned to see Luffy, Zoro, and Sanji inside a bubble. Sanji, with heart-shaped eyes, shouted, "Nami-chan! Robin-chan!" Itachi sighed and said, "You don't have to interfere."

Zoro smirked. "Yeah, I can tell."

From the ship, a voice shouted, "Hey, wake up, Wadatsumi! Avenge yourself and get back in the fight!"

Itachi stepped onto the ship, followed by Luffy, Zoro, and Sanji. Itachi asked, "What happened?"

Luffy replied, "Well, Sanji's bubble popped, and we ended up with Zoro. We landed, and I thought I was gonna die."

From behind, Nami chimed in, "Don't make us worry!" Chopper, crying, added, "Luffy, I was so scared!"

Zoro, standing next to Itachi, glanced at his sword and said, "Still using that sword, huh?"

Itachi looked at him and replied, "Yeah, it's a great sword."

Zoro smirked. "I sensed your Haki, but it felt weak."

Itachi understood what Zoro meant. "I don't know, but when I use my Eternal Mangekyō Sharingan, my Conqueror's Haki activates—just in small amounts."

Zoro made a thinking face. "I think when you use it, you might be tapping into both your own power and will. That might explain it."

Itachi nodded. "I've come to the same conclusion."

Zoro smirked again. "Well, after two years, we could spar... normally."

Itachi smiled. "Yeah, but it might wreck the ship."

Zoro chuckled. "Yeah."

Robin approached Itachi and said, "You did well." Itachi glanced at her and smiled. Robin smiled back, but with a blush, she added, "But don't worry me like that..."

Itachi, blushing slightly himself, nodded and replied, "I won't do it again."

As the Thousand Sunny settled on top of the Kraken's head, Luffy grinned and declared, "I'm gonna turn Surume into a top-notch navigator!"

Usopp looked a little uneasy, waving his hands. "Just make sure the ship doesn't get crushed, alright?"

Before anyone could respond, a rumbling noise echoed through the area. Nami's eyes widened as she glanced toward the volcanoes. "The volcano's about to erupt!"

Vander Decken's crew immediately panicked, and their captain shouted, "Pull out! Wadatsumi, Ankoro, get the ship out of here!"

Surume, hearing the command, quickly moved the Sunny away. Both ships managed to put some distance between themselves and the volcano before it erupted. The explosion sent a massive shockwave through the sea, blowing away the Flying Dutchman, Wadatsumi, and Ankoro in the process.

Surume, however, kept his speed, swimming ahead of the lava flow as it cascaded down the side of the volcano. The Kraken leapt into a darker area, diving into a trench as another eruption triggered an avalanche. Rocks tumbled down, smashing into the trench, and a boulder fell onto Surume, knocking him out.

The Thousand Sunny plummeted into the abyss alongside the unconscious Kraken.

When the dust settled, the Straw Hats found themselves miraculously unharmed, though the Sunny had landed on its side at the ocean floor. Luffy groaned, rubbing his head. "Well, that was a ride."

The crew climbed out, glancing around the eerie, deep-sea landscape. Then, a faint glow caught their attention.

"Hey," Franky pointed. "What's that light over there?"

Nami gasped, her eyes lighting up with realization. "It's Fish-Man Island! We made it!"
