Sailing: I was falsely accused of watching Nami bathe, but I'm blind.

Sailing: Accused of Watching Nami Take a Bath, But I'm Blind Author: Shy Factory Girl from the Music Bureau

He transmigrated and became a member of the sea, only to be falsely accused by Sanji of spying on Nami while she was bathing.

LOL, I was born blind!

Was the cook framed on purpose? Did Luffy and Zoro expel me without even asking questions? Do the Straw Hat crew all think I'm a burden to be sacrificed?

it is good!very good!

While everyone thought I was a piece of trash that could be discarded at will, they didn't know that my "insight" had already seen through everything!

[Ultimate Observation Haki] allows one to see the essence of all things; [Mind's Eye Sword Path] cuts through false rules!

When darkness becomes my only perception, the ultimate Observation Haki becomes my eyes to see the world!

They stole my trust and my sense of belonging, so I will use absolute justice to overturn this ocean!

Marineford? Perfect, let's use "Fire Fist" Ace as a sacrifice first!

Becoming Fujitora's apprentice, joining the Navy, codenamed "Mingyan"? No, this is just the beginning!

I, Kai, will use the knife in my hand to uphold my justice, cut through this sea, and crush all hypocrisy!

Straw Hat Luffy, are you ready to reap the bitter fruits of your own making?!

Chapter 1 Blind Kai

The sea, like a vast, dark ribbon, rippled gently under the faint starlight. The Going Merry sailed smoothly through the first half of the Grand Line, the night breeze carrying a salty, refreshing scent that caressed the faces of every crew member. Most on deck were fast asleep, except for the figure on watch and one who maintained a peculiar posture: Kai. He stood silently at the ship's railing, facing the boundless, dark sea, his body swaying slightly with the ship's rhythm, as if he had become one with the ship and the sea. His ears twitched slightly, catching the subtle sounds imperceptible to others, his skin sensing the delicate changes in air pressure and humidity.

Suddenly, Kai turned his head slightly and spoke towards the helm, his voice calm yet carrying an undeniable certainty: "Nami, prepare for the storm. We'll arrive in about half an hour. Wind force 7, northwest. Waves will exceed five meters. We need to adjust our angle eastward by fifteen degrees, otherwise we'll be swept into the strong currents that have deviated from our planned course." His voice wasn't loud, but it was exceptionally clear in the quiet night, piercing through the low roar of the waves.

Nami, who was checking the nautical charts in the navigation room, was startled by the sound. She quickly walked to the door, poked her head out, and said with a hint of surprise and habitual reliance on her face, "Kai? The weather looks calm right now, and there are no obvious cyclone markers on the charts." Although she said this, her hand had already begun to subconsciously prepare to turn the rudder. She knew Kai's sudden warnings all too well; they were almost never wrong, and their accuracy even surpassed that of her most sophisticated instruments and richest experience.

Kai didn't "look" at Nami; his face remained turned towards the direction of the sea breeze, as if listening to distant whispers. "The moisture in the air is condensing rapidly, the seabirds are dropping sharply, and the sound of the waves in the distance is becoming heavy and chaotic—clear signs of a gathering storm. Trust my senses, Nami, adjust immediately." His tone was devoid of emotion, simply stating a fact that was about to unfold. This calmness, ironically, made Nami even more convinced.

“I understand!” Nami didn’t hesitate any longer, quickly returning to the helm and adjusting the course according to Kai’s instructions. She muttered to herself, “What a monstrous intuition, more accurate than my navigation skills.” Like the other crew members, she had long been accustomed to attributing Kai’s extraordinary perception to some kind of innate “sixth sense,” or perhaps incredibly sharp hearing and intuition. After all, Kai was usually very agile, even surpassing normal people in some aspects; who would have thought that such a trustworthy partner was actually blind?

Half an hour later, just as Kai had predicted, a violent storm swept in. The sea instantly became menacing, with giant waves crashing against the ship with a deafening roar. However, because they had adjusted their course in advance, the Going Merry, despite the violent rocking, remained steadily in relatively safe waters, avoiding the powerful ocean current that would have kept them off course for days. Nami gripped the helm tightly, her trust in Kai deepening even further.

After the storm, the morning sun shone brightly on the deck. The crew members emerged from their cabins, breathing in the fresh, post-rain air. Chopper was carefully drying some herbs that had been soaked by the rain when, in a moment of carelessness, a sea breeze blew, and several precious herbs slipped off the drying net and fell towards the deck. Chopper cried out in alarm, trying to catch them, but it was too late.

Just then, Kai, who had been standing quietly not far away, moved. He didn't even turn around; he simply shifted his body slightly, and with an extremely smooth and natural movement, his five fingers accurately caught the few falling herbs in mid-air, holding them steadily in his palm. The whole process was as fast as a blur, as precise as if it had been calculated countless times.

"Wow! Kai, you're amazing! Your eyes and hands are so fast!" Usopp happened to witness this and couldn't help but exclaim in admiration, his eyes shining with worship. "Your reaction speed is incredible! It's like you have eyes in the back of your head!"

Kai handed the herbs back to Chopper, his face still calm and expressionless. He simply nodded and replied, "I just happened to sense it." He never explained how he did it, because it was too complicated, and no one would believe him anyway. He was used to this kind of praise based on misunderstanding.

Chopper took the herbs and looked at Kai gratefully, "Thank you, Kai! These herbs are very important." It patted its chest with its little hoof, seemingly still feeling the lingering fear from the accident.

Kai tilted his ear slightly, trying to catch the emotion in Chopper's voice, and the corners of his mouth curved upwards almost imperceptibly: "You're welcome. Take good care of them."

No one noticed that throughout the entire process, Kai's gaze remained unfocused. His pupils were deep and still, as if veiled by a thin mist, unresponsive to changes in the surrounding light. He never actively used his "eyes" to follow moving objects or speaking people, but rather relied on the source of sound, the flow of breath, the breeze stirred by moving objects, and that nascent "perception" that even he himself hadn't fully understood. These details were unconsciously overlooked by the crew, or they interpreted them as Kai's introverted nature, his aversion to eye contact, or perhaps a unique way of focusing on his surroundings.

A little later, Robin also came onto the deck, holding a rubbing of an ancient inscribed stone tablet, lost in thought. She walked over to Kai and asked softly, "Kai, do you feel anything special about the texture of these lines? I always feel that the way these lines are arranged contains a certain rhythm." She knew that although Kai was blind, his sense of touch was exceptionally keen, and he could sometimes offer unique insights from different angles.

Kai stretched out his finger and gently stroked the uneven texture of the rubbing. His fingertip was like the most precise probe, carefully sensing every turn, the depth of every engraving, and the shape of every edge. "Hmm," he pondered for a moment, "these lines are ancient, the engraving technique is very steady, but there is a subtle pause and a concentration of power at the turns. It's not like a simple record of words, but more like a... map of energy flow, or rather, a sealed mark. When I touch them, I can feel a faint, dormant aura."

A flicker of surprise and admiration crossed Robin's eyes: "A pattern of energy flow? A seal? That's a truly unique sensation. Thank you, Kai, this has given me some new perspectives." She had always felt that Kai was an enigma; his perception of the world was completely different from ordinary people, yet exceptionally precise and profound. She respected his differences and appreciated his unique sensitivity.

Kai simply nodded slightly, turning his attention back to the distant sea, feeling the warmth of the sun on his skin, listening to the cries of seagulls soaring through the sky, continuing to immerse himself in his silent, lightless, yet incredibly rich sensory world. Life on the ship continued day after day, filled with adventure and laughter, but also with misunderstandings and estrangement, and all of this seemed to be merely the prelude to some huge turning point in the future.

Chapter 2 Sanji's Jealousy!

The lunch bell rang, and an enticing aroma immediately filled the kitchen. Sanji was wielding a kitchen knife, deftly processing various ingredients while humming an off-key love song. Kai, meanwhile, sat quietly on a small stool nearby, holding a potato and a peeler, helping out. His movements seemed slow, even somewhat mechanical, but his efficiency was surprisingly high. Thin potato skins were peeled off neatly like ribbons, falling into the bucket beside him, while the potato itself was smooth and round, with almost no unnecessary cuts or damage to the flesh.

Sanji occasionally glanced at Kai, noticing the small mountain of potatoes piled up in front of him. Looking at his own team's varied but slower-paced preparations, a subtle, inexplicable displeasure rose within him. This displeasure was complex, a mixture of admiration for Kai's efficiency and focus, an inexplicable sense of competition, and perhaps even a hint of defeat at being outdone, especially in his prized culinary field—even something as simple as peeling potatoes.

"Hey, Kai," Sanji said in a joking tone, trying to hide his little scheme, "You're amazing, you could do a job so well even with your eyes closed. Have you secretly practiced some kind of unparalleled swordsmanship?" As he spoke, he exaggeratedly twirled his sword, almost slicing the onion next to him away.

Kai's hands didn't pause for a moment; he didn't even look up, simply replying calmly, "Practice makes perfect." He could clearly "hear" the slight awkwardness in Sanji's tone, but he chose to ignore it. On the ship, he had long been accustomed to being the center of attention and jokes, and he was used to responding with silence and the most concise language.

Just then, Nami walked into the kitchen with a sea chart in her hand, her face showing a hint of excitement and anticipation. "Sanji-kun, is lunch almost ready? Kai, it's perfect that you're here too, let's discuss our next stop, 'Whispering Town.' The chart says it's a very bustling port, and there's even a famous hot spring inn!" she said, spreading the sea chart out on the table beside her.

Kai stopped what he was doing, turned slightly to face the direction from which Nami's voice came. "Whispering Town," he repeated the name, then closed his eyes (though it made no difference to him), listening intently to the various sounds coming from the open kitchen window. "I hear the seagulls' cries are getting higher, and their circling seems to be concentrated in the southeast. The sound of the water lapping against the hull is also becoming more regular, with an echo that seems closer to land. Judging from the wind direction and our current speed, we should be able to see the outline of Whispering Town in less than two hours; the location is basically accurate." He was like someone deciphering an invisible sound map, combining and analyzing various subtle sound information to arrive at a precise conclusion.

Nami once again showed a surprised yet matter-of-fact expression: "Wow, Kai, you can even 'hear' this? You're so reliable! With you around, I feel that sailing is much easier." She didn't hold back her praise; in her opinion, Kai's ability was invaluable in navigation.

Sanji listened to Nami praising Kai, and a barely perceptible pang of jealousy resurfaced in his heart. He felt that ever since Kai joined the crew, Nami and Robin seemed more willing to talk to this taciturn guy, especially when discussing serious matters. Perhaps it was because Kai was always so calm and composed, never losing his composure like himself when he saw beautiful women? Or was it because his "magical" abilities were indeed very useful? Sanji pursed his lips, sped up his chopping, making even louder noises, trying to attract the attention of the two ladies.

Soon, a sumptuous lunch was laid out on the table. Luffy was the first to rush over, grabbing large chunks of meat and stuffing them into his mouth, his mouth dripping with oil as he mumbled "Delicious!" In the chaos, a piece of meat covered in sauce flew off Luffy's fork and hit Kai squarely in the face.

For a moment, the atmosphere at the table froze. Nami frowned, Usopp gaped, and Sanji stopped his fawning. Everyone stared at Kai, waiting for his reaction. However, Kai only paused for a moment, then silently picked up a napkin and calmly and carefully wiped the food crumbs and sauce from his face. There was no disgust, anger, or embarrassment on his face, not even a twitch of his muscles, as if he had simply been brushed aside by the wind. After wiping himself clean, he nonchalantly picked up his cutlery and prepared to eat.

This subtle moment, devoid of the emotional response expected of a normal person, was once again overlooked by everyone. Luffy casually apologized and then continued to eat with his head down. The others were quickly drawn back to the lively atmosphere at the table, and no one delved into the reason behind Kai's overly calm reaction. It was because he simply couldn't "see" how the food had unpleasantly gotten on his face; all he felt was a sudden foreign object on his face and a change in temperature.

Sanji looked at Kai's overly calm face, then at Nami's beaming smile and Robin's gentle grin, and the indescribable feeling in his heart became even clearer. This Kai, despite being a newcomer, always managed to integrate into the group in a peculiar way, even gaining more respect and trust than him, the "veteran," in some ways. Especially Nami and Robin—their calm and natural manner when speaking to Kai made Sanji feel a surge of inexplicable anger. He decided that when they arrived in Whispering Town, he would definitely make a good impression and show Nami and Robin who the most reliable and gentlemanly man on the ship truly was.

Kai ate his lunch quietly, savoring the taste and texture of the food. He could sense the emotional fluctuations of everyone at the table: Luffy's pure appetite, Nami's cheerfulness, Usopp's chatter, Zoro's quietness, Chopper's innocence, Robin's composure, and even Sanji's subtle, negative emotions hidden beneath his enthusiastic exterior. He silently absorbed all of this, continuing to play the role of the silent, reliable, yet enigmatic crew member. He knew that as long as he didn't actively uncover the secret, this harmony based on misunderstanding might continue indefinitely. However, secrets always carry the risk of being discovered, and misunderstandings, in some unguarded moment, could ferment into an irreversible poison.

The peaceful voyage didn't last long. The weather on the Grand Line is unpredictable; one moment the sky was clear, the next, an ominous cloud had rolled in. Worse still, beneath the cloud, several pirate ships flying the skull and crossbow flag were menacingly closing in on the Going Merry. Usopp on the lookout immediately sounded the alarm: "Enemy attack! It's the 'Black Shark' Pirates! They have three ships, and they're closing in from the left and right!"

"What? These guys are relentless!" Nami's expression changed. The Black Shark Pirates were notorious raiders in the nearby waters, known for their ferocity and cunning.

Upon hearing there was a fight, Luffy immediately became excited, cracking his knuckles: "Oh! Perfect for stretching my muscles! Ladies, prepare for battle!"

Chapter 3 The Ultimate Observation Haki!

Zoro gripped the hilt of his sword, his eyes sharpening. Sanji immediately shielded Nami and Robin, assuming a fighting stance. Chopper also transformed into his beast form, ready to provide support.

Kai remained standing on the ship's railing, his back to the cabin, facing the direction of the approaching enemy. He wasn't as fired up as Luffy and his crew, nor as tense as Nami; his expression remained calm, but his body was slightly taut, like a fully drawn bow. His senses expanded with unprecedented intensity, covering the surrounding sea and the approaching enemy ships. The murderous aura in the air, the pounding of enemy hearts, the sound of ships breaking the surface, even the subtle metallic scraping of cannonballs being loaded—all were clearly fed into his mind, forming a dynamic, three-dimensional "image" of the battlefield.

"The ship to our left has five men on the foredeck, two with guns and three with knives. They are expected to be within musket range in ten seconds. The ship to our right has its broadside gun ports open, and three cannons are aiming at our mainmast." Kai's voice rang out clearly, like a prophet on the battlefield, accurately reporting the enemy's movements and threats.

"Damn it! Are they trying to break our masts?" Nami immediately ordered the ship to adjust its course in an attempt to avoid the cannon fire.

"Leave it to me!" Luffy shouted, "Gum-Gum Rocket!" He stretched out his arms and blasted the enemy ship to his right.

Almost simultaneously, Kai spoke again: "Luffy, the two behind you on the right! Prepare to board the ship with the grappling hook from near where you bounced back!" His warning was half a beat faster than the enemy's actual action.

Sure enough, under the cover of Luffy's attack, two members of the Black Shark Pirates darted across the gap between the two ships like ghosts, their gleaming grappling hooks aimed straight for Luffy's back. But thanks to Kai's warning, Luffy twisted his body mid-air and kicked the two men back into the sea.

"Zoro, cannonballs from above!" Kai's voice rang out again.

Zoro didn't even look up. Relying on his absolute trust in Kai's warning, he suddenly lowered his body and shouted, "Three-Sword Style: Demon Slash!" The sharp blade slashed upwards, splitting a whistling cannonball in two, which exploded in mid-air, scattering fire and fragments everywhere.

The battle quickly intensified. Relying on their numerical superiority, the enemy launched relentless attacks, bullets, shells, and melee weapons weaving a dense web of fire. The deck of the Going Merry was instantly filled with peril. However, thanks to Kai's continuous and accurate warnings, the Straw Hat crew always managed to react at the most crucial moments, defusing crisis after crisis.

"Sanji, watch your step! Someone's diving from underwater at three o'clock!"

"Chopper, cover Nami! There's a stray bullet on starboard!"

"Usopp, your slingshot is off to the left by three degrees. Correct it!"

Kai was like a tireless battlefield commander; his voice, though not loud, always pierced through the noise and reached the ears of every comrade. He himself moved like a ghost along the ship's side, his body always half a step or even a full step ahead, dodging stray bullets and flashing blades with minimal movement. He never attacked first; all his movements revolved around "perception" and "evasion." He kept his eyes closed (though this was the norm for him), yet his body was exceptionally agile and swift; every sidestep, crouch, and lateral movement was perfectly timed to evade fatal attacks.

To onlookers, Kai seemed to possess almost supernatural dynamic vision and reaction speed, as if he could see through every attack trajectory and predict every move of his enemies. Usopp was dumbfounded, muttering to himself, "Has Kai really gained 'mind's eye'? He's too strong!"

The battle lasted for about fifteen minutes. With the Straw Hat crew's strong individual strength and Kai's precise battlefield support, the Black Shark Pirates' three ships were shattered and suffered heavy casualties, ultimately forcing them to retreat in a sorry state.

After the battle, the deck was a mess, but thankfully no one was seriously injured. Chopper busied himself treating the wounds of his injured companions. He ran to Kai and noticed a shallow cut on Kai's arm, from a weapon, that was oozing blood.

"Kai, you're hurt!" Chopper said with concern, taking out his first-aid kit. "Why didn't you move aside? Let me bandage you up."

Kai let Chopper treat his wound, his face remaining expressionless. "I sensed it a little too late; I avoided a vital spot," he said casually. In fact, the wound was caused when he was simultaneously alerting to threats from three different directions, his attention was slightly diverted, and he failed to perfectly dodge a sharp, piercing blade.

As Chopper carefully disinfected and bandaged him, he looked up curiously and asked, "Kai, how do you 'see' so many attacks? Sometimes the enemy is clearly hiding in the smoke, or attacking from a very tricky angle, but you can still spot them in advance. That's amazing!" Chopper's eyes were filled with pure curiosity and admiration.

Kai paused for a moment, then answered in his usual vague manner, "I just... focused very intently on listening and feeling. The sound of the wind, breathing, the sound of weapons cutting through the air, and the... well, intentions emanating from them. Combining these, I could roughly determine their location and actions." He tried to explain in terms that ordinary people could understand, but in reality, the kind of ability that transcended the five senses that he relied on was far more complex than that.

"Wow! I see!" Chopper nodded, seemingly understanding, interpreting it as an extremely advanced technique for focusing during combat. "Kai, you're a genius!"

Kai didn't speak again, only feeling the slight constriction from the bandages on his arm. He knew that his explanation had once again successfully concealed the truth beneath a seemingly reasonable pretext. The crew had become accustomed to his "extraordinary performance" and had spontaneously found "logical" explanations for it. This misunderstanding acted as a protective shell, allowing him to remain safely within the group, but also as an invisible wall, isolating him from his comrades. He looked down at his bandaged arm, a complex emotion that no one could understand passing through his mind. How long could this continue?

Night fell again, and the sea returned to its deep and tranquil state. After a day of fighting, most of the crew had long since fallen asleep, the cabins filled with the even sound of breathing. Kai volunteered for the first half of the night's watch. He stood alone at the bow, facing the cool sea breeze, quietly "standing." For him, the watch wasn't about sight, but about extending his senses as far as possible, like an invisible net covering the waters around the Going Merry. The rise and fall of the waves, the movement of schools of fish, the outlines of distant islands, even the surging of the undercurrents, were all vividly present in his "mental image." This was a unique "watch" of his own.

I can show you Chapter 4, but you'll have to pay!

The sea, like a vast, dark ribbon, rippled gently under the faint starlight. The Going Merry sailed smoothly through the first half of the Grand Line, the night breeze carrying a salty, refreshing scent that caressed the faces of every crew member. Most on deck were fast asleep, except for the figure on watch and one who maintained a peculiar posture: Kai. He stood silently at the ship's railing, facing the boundless, dark sea, his body swaying slightly with the ship's rhythm, as if he had become one with the ship and the sea. His ears twitched slightly, catching the subtle sounds imperceptible to others, his skin sensing the delicate changes in air pressure and humidity.

Suddenly, Kai turned his head slightly and spoke towards the helm, his voice calm yet carrying an undeniable certainty: "Nami, prepare for the storm. We'll arrive in about half an hour. Wind force 7, northwest direction. Waves will exceed five meters. We need to adjust our angle eastward by fifteen degrees, otherwise we'll be swept into strong currents that deviate from our planned course." His voice wasn't loud, but it was exceptionally clear in the quiet night, piercing through the low roar of the waves.

She quickly walked to the door, poked her head out, and said with a hint of surprise and habitual reliance on her face, "Kai?

Half an hour later, just as Kai had predicted, a violent storm swept in. The sea instantly became menacing, with giant waves crashing against the ship with a deafening roar. However, because they had adjusted their course in advance, the Going Merry, despite the violent rocking, remained steadily in relatively safe waters, avoiding the powerful ocean current that would have kept them off course for days. Nami gripped the helm tightly, her trust in Kai deepening even further.

After the storm, the morning sun shone brightly on the deck. The crew members emerged from their cabins, breathing in the fresh, post-rain air. Chopper was carefully drying some herbs that had been soaked by the rain when, in a moment of carelessness, a sea breeze blew, and several precious herbs slipped off the drying net and fell towards the deck.

The whole process was as fast as a blur, as precise as if it had been calculated countless times.

"Wow! Kai, you're amazing! Your eyes and hands are so fast!" Usopp happened to witness this and couldn't help but exclaim in admiration, his eyes shining with worship. "Your reaction speed is incredible! It's like you have eyes in the back of your head!"

She knew that although Kai was blind, his sense of touch was exceptionally keen, and he could sometimes offer unique insights from different angles.
