One Piece: With Sign-in System

For the next while, the group settled temporarily on the Sabaody Archipelago. 

While Rayleigh helped coat The Traveler for their undersea journey, Bonney used her abilities to transform Kuina, Robin, and Conis into little girls of various ages, disguising them to avoid attention. 

The archipelago was swarming with wanted posters of them and Ron. If word got out about their presence, Kizaru would likely come chasing again. 

As for Ron, after being turned into a ten-year-old boy, he spent his days either training his body by diving into the ocean's depths to endure the pressure or traveling to nearby islands to complete his sign-in rituals. 

---

One particular day...

Ron, still in his ten-year-old form, arrived at Amazon Lily, the island in the Calm Belt, home to the Kuja tribe. Without alerting anyone, he quietly landed on the island. 

The moment his feet touched the ground, a familiar system notification rang in his ears: 

[Ding! The host has arrived at Amazon Lily, fulfilling the sign-in condition. Proceed with sign-in?]

"Sign in," Ron responded without hesitation. 

[Ding! Sign-in successful. Rewards obtained: +10 Vitality. 

Sealed Item Obtained: Sealed Tenseigan.]

Hearing the reward, Ron was momentarily stunned. 

"Tenseigan? Could it be the Tenseigan from the world of Naruto?"

"Sealed?"

"What kind of nonsense is this?"

Sitting beneath a tree in the Amazon Lily forest, Ron closed his eyes and accessed the item's details. 

---

[Sealed Tenseigan

- A visual jutsu from another world with the power to create and destroy worlds.

- Currently in a sealed state.

- Can be fused with the host's eyes immediately.

- However, until the seal is undone, its abilities cannot be utilized.

- Fusion requires immense vitality and mental strength to sustain.

- Once fused, the host will be unable to open their eyes until the seal is undone.

- Proceed with fusion?]

---

After reviewing the description, Ron felt completely at a loss. 

"It really is that Tenseigan… but why is it sealed?"

"If I don't fuse it, it's just a useless trinket sitting in the system space. But if I do fuse it, I won't be able to use its powers until the seal is undone. I'd essentially be blind."

"System, how long would it take to break the seal?" Ron asked internally. 

[Based on your current vitality and mental strength, approximately three years.]

Ron's youthful, innocent face twisted into a bitter smile. 

"Three years of blindness... Is that the price for gaining the power of the Tenseigan?" 

After pondering for a while, Ron quickly made up his mind. 

For someone who had mastered Observation Haki and the Transparent World, losing his sight wouldn't be much of a hindrance. He could still perceive everything around him clearly. 

Compared to the price, the power of the Tenseigan was undoubtedly worth it. 

Without hesitation, Ron murmured in his heart: "Fuse." 

---

In an instant, an overwhelming and fiery energy surged into his eyes! 

Pain.

An indescribable agony. 

It felt as if his eyes were being incinerated by the sun, as if his very soul was being burned! 

Even Ron, who had endured countless hardships, couldn't suppress the pain. Clutching his face with both hands, he let out a beast-like growl. 

"AAAAAAAHHHH!" 

A deafening roar erupted as his black hair whipped wildly around him, his unleashed aura forming a storm that snapped trees and tore up the earth, sending debris flying in all directions. 

Unconsciously, his Conqueror's Haki burst out with his anguished cries. Crimson ripples of power spread across the entire island, causing weaker-willed Kuja citizens to faint instantly. 

Even the strongest warriors of Amazon Lily stood frozen in shock. 

"Conqueror's Haki? Is it Lady Boa Hancock? Or... someone else?" 

As the skies over Amazon Lily darkened, fierce winds howled, and crimson lightning snakes coiled within the thick clouds, roaring with an ear-splitting intensity. 

Inside the grand palace, atop its towering spires, Boa Hancock, the Pirate Empress, abruptly opened her eyes while bathing in the hot springs. 

"Who dares?!" 

Without delay, she donned her robes and, flanked by her sisters, Sandersonia and Marigold, along with a contingent of Kuja warriors, marched toward the forest where the disturbance originated. 

At the forest's center, an open clearing had appeared, the trees reduced to splinters by the explosion of energy. 

In the middle of the crater stood a ten-year-old boy with black hair flowing wildly. His eyes were shut tightly, and trails of fresh blood dripped from the corners of his eyes. 

"A child?" 

Marguerite, one of the Kuja warriors, observed in disbelief. 

Could this little boy truly be the source of that overwhelming Conqueror's Haki? 

How was that even possible? 

Under the watchful eyes of everyone, Boa Hancock stepped forward and addressed him, her voice commanding: 

"Was it you who released that Conqueror's Haki just now?" 

Hearing her voice, Ron slightly tilted his head toward her, though his eyes remained closed. "Who are you?" 

Sandersonia scoffed, "Child, do you not know the ruler of this island? You stand before Boa Hancock, the Empress of Amazon Lily!" 

Boa Hancock...

Ron instantly pieced everything together. 

Before he could respond, Marigold interjected, her tone sharp: "Answer clearly. Was that your Conqueror's Haki just now?" 

---

Ron sighed inwardly. 'Did I release my Conqueror's Haki unconsciously?'

No wonder they all came rushing here. 

With his Transparent World activated, Ron's heightened senses allowed him to perceive their presence, heartbeats, and even their emotional states. 

These women bore no hostility toward him, only wariness and curiosity—likely due to his current childlike appearance. 

Still, his silence seemed to aggravate Marigold. 

"How rude!" Marigold hissed, her irritation evident. "Sister, allow me to capture her!" 

Her assumption was natural, given that everyone on Amazon Lily was female. With Ron's shoulder-length hair and small frame, he did resemble a girl. 

Boa Hancock raised a hand to stop her. "Someone capable of releasing such powerful Conqueror's Haki is not someone you can handle." 

She approached Ron, her piercing gaze locked on him. "What is your name? And what happened to your eyes?" 

---

Ron chuckled softly at her authoritative tone. 'So this is the voice of the world's most beautiful woman... Too bad I can't see her face now. I should've taken a good look before fusing with the Tenseigan.'

He lifted his head, smiling faintly despite his closed eyes. 

"My name is Ron, a traveler. Nice to meet you, Pirate Empress." 

"Traveler Ron?" 

Boa Hancock furrowed her brows, the name ringing a faint bell. 

But before anyone could react further, the scene took a dramatic turn. 

In the blink of an eye, the ten-year-old black-haired "girl" transformed into a tall, lean, and well-built young man with strikingly handsome features and a calm demeanor. His sudden growth left him standing even taller than Boa Hancock herself. 

The abrupt transformation brought him so close to her that their noses almost touched. 

"Ah, looks like Bonney's power wore off," Ron murmured with a playful grin. "You have a lovely scent, by the way." 

Boa Hancock's eyes widened in shock. 

"A... man?!" 

Sandersonia's startled voice rang out behind her. 

Realizing the truth, Boa Hancock's expression hardened. Without hesitation, her leg shot up in a powerful kick. 

Ron reacted swiftly, raising a hand to block her strike. 

BOOM!

The clash of their forces sent shockwaves rippling outward, toppling trees and stirring the air like a tempest. 

The rest of the Kuja warriors immediately readied their weapons, their arrows imbued with Haki as they aimed at the now shirtless black-haired young man. 

"So this is what a man looks like?" 

Margaret, gripping her bow, stared at Ron with a mixture of curiosity and wonder. "Can men really grow and shrink like that?" 

---

Meanwhile, Boa Hancock narrowed her eyes, her voice icy. 

"Traveler Ron... Now I remember. It's you." 

Her gaze bore into him. "Why have you come to Amazon Lily? What is your purpose here?" 

Ron chuckled softly, his eyes still closed, and said in Hancock's direction, "If I said I was just here for sightseeing… would you believe me?" 

Hancock's expression darkened, her piercing gaze growing colder as she leapt back, creating some distance. 

Raising her hands in front of her chest, she formed a heart shape and called out, "Mero Mero Mellow!"

The heart-shaped beam shot directly toward Ron. 

However, to everyone's astonishment, Ron remained completely unaffected. 

"What?! It didn't work?" 

"Could it be because he kept his eyes closed the whole time and didn't see Sister's unparalleled beauty, so he wasn't moved?" 

A bead of sweat slid down Marigold's temple as she speculated aloud. 

"Or perhaps…" she continued, "he already knew Sister's abilities and prepared countermeasures in advance. This guy… did he come here specifically targeting Sister?" 

Hancock's expression turned icy, her face tinged with suspicion. 'Is this man here just for me? What is his true purpose?'

"You think this will stop me?" Hancock's voice was laced with cold fury as she suddenly lunged forward, her figure disappearing in a blur of speed. 

"Perfume Femur!"

Her leg, coated with Armament Haki, came crashing toward Ron with devastating force. 

Through his Transparent World ability, Ron sensed the power behind the strike. It carried an intensity that was on par with—or perhaps slightly greater than—his current strength. However, it hadn't yet reached the third stage of Armament Haki. 

With a faint smile, Ron activated Shave. His body vanished the moment Hancock's kick was about to land, evading her attack entirely. 

"He disappeared?" 

"Where did he go?" 

"I can't sense him!" 

The Kuja warriors, armed with Haki-imbued bows, frantically scanned the area, their vigilance heightened. 

Hancock spread her Observation Haki across the surroundings. Sensing a faint trace of Ron's presence, she immediately looked up. 

Suspended midair, the shirtless black-haired youth hovered effortlessly. His lips curved into a teasing smile as he addressed her. 

"Such a pity I didn't get to see the face of the Pirate Empress this time. Let's hope I'll have the chance next time." 

"Slave Arrow!" 

Hancock touched her finger to her lips, forming a massive pink heart-shaped energy construct. She pulled it back like a bow and released a torrent of pink arrows into the sky, all aimed at Ron. 

These arrows, enchanted by her abilities, would petrify anyone they touched, regardless of whether they were enamored by her beauty or not. 

Ron, sensing the incoming attack through Transparent World, stepped downward with force, causing the air beneath him to explode with a deafening roar. His body shot upward, swiftly evading the pink projectiles and ascending into the unreachable heights of the sky. 

"Farewell." 

Ron's voice, tinged with laughter, echoed as his figure disappeared into the clouds above. 

Hancock, retracting her abilities, stood still. Her gaze lingered on the sky where Ron had vanished. Her brows furrowed slightly, a mixture of confusion and frustration flickering in her expression. 

"That man… what was he really here for?"
