In a dark, damp room, a foul smell of mold and cold moisture filled the air, seeping deep into the bones. The rough stone walls were covered with a thin layer of dew, and the only faint light slipped through a narrow crack in the high ceiling, barely dispersing the dense darkness.
Standing in the middle of this desolate place was a young man wearing dull gray prison clothes, slightly torn at the sides. His short black hair clung to his damp forehead, and his pale face reflected exhaustion and shock. His physique was well-proportioned and handsome—his muscles tense but not bulky—and he looked about sixteen or seventeen years old. He stared in complete disbelief at his reflection in a small puddle of water on the ground, as if his eyes refused to accept what they saw.
"Have I… really been transported to another world?"
Kyle muttered in a low, slightly trembling voice, wiping his eyes in confusion as he slowly looked around. He had spent many years reading isekai novels about traveling between worlds, dreaming of extraordinary adventures and immense powers—but he had never imagined it would actually happen to him. He had expected to wake up in his bed as usual, but reality now was completely different.
He took a deep breath, trying to calm his racing heartbeat.
"Well then… since I've been transported here, I might as well accept it and start over! I won't waste this opportunity."
Ding!
"The host has been detected by the Sovereignty of Worlds System. Initiating binding now!"
A sudden, clear mechanical voice rang inside Kyle's mind, echoing through every cell of his body.
Kyle spoke with excitement filling his voice: "Amazing! There must be some kind of cheat ability that will let me progress insanely fast—something that will turn me into a legend in this world!"
"The Sovereignty of Worlds System has been successfully bound!"
"How powerful are you exactly when it comes to conquering worlds?"
Kyle asked eagerly, curious about the true extent of this system that had suddenly appeared.
The system replied in a calm and confident tone: "This system allows the host to master a variety of skills with absolute ease and astonishing speed. For example: complete ninja techniques from the world of Naruto, Kidō arts from Bleach, Devil Fruit abilities, and even divine powers from higher realms."
Kyle didn't seem too impressed. Instead, he replied with slight disdain: "That exists in most systems I've read about. The real secret lies in the price one must pay for these abilities. Nothing in life… or in other worlds… is free."
He was not easily deceived after everything he had read.
"That is precisely where the strength of this system lies; the host only needs to pay a very small price to obtain all these abilities without any serious consequences."
Kyle asked, increasingly astonished: "Really?"
"Of course! If you don't believe it, you may open the beginner's gift package and see for yourself."
"Open the beginner's gift package!"
"There are three options. Would you like to view them?"
"Show them now!"
The system explained:
"Option one: the Immortal Sage Body + the Eternal Forest Control Arts.
Option two: the Crimson Eye of Fate + the Cursed Eye Techniques of the Shadow Clan.
Option three: the complete legacy of forbidden ninja arts from the Village of Shadows."
Kyle felt a powerful shock and complete astonishment. These options were legendary—any one of them alone would be enough for him to walk the world with unmatched confidence.
He asked, puzzled: "I understand the first and second, but what exactly does 'the complete legacy of forbidden ninja arts from the Village of Shadows' mean?"
"It includes all ninja arts except for those in the first and second options."
"Wait! Does that mean it includes the Eight Forbidden Gates of Wrath, the Instant Divine Thunder Teleportation Technique, and all the other powerful techniques?" Kyle's eyes lit up.
"That is absolutely correct."
"Well then… I choose the third!"
"Activating…"
"Congratulations to the host! The following have been activated: the Instant Divine Thunder Teleportation Technique, the Phantom Shadow Multiplication Art, the Devastating Spiritual Vortex Sphere, the Piercing Lightning Blade…"
"Special notice: with the activation of these techniques, the host has also obtained 'Inner Spiritual Energy.' The stronger you become, the more your spiritual energy will increase automatically. Good luck on your journey, Kyle!"
Inside the dark, damp prison cell, the notifications echoed within Kyle's mind like a wave of surging excitement. He felt an immense power rushing through his body, as if every cell within him was awakening from a long slumber. He was overwhelmed with exhilaration; from the moment he arrived in this new world, he was already on the verge of becoming an exceptional and powerful expert capable of defying the impossible with ease.
Kyle laughed loudly, his voice filling the narrow cell:
"Hahaha! From now on, I will conquer both the heavens and the earth! So tell me, System—what world am I in right now?"
The system replied in its calm, clear mechanical voice: "This is the world of One Piece. To learn the details of your current identity, please merge with the memories of the body you have transmigrated into."
"Merge? How exactly does that wor—"
Before Kyle could finish his sentence, a massive and sudden wave of information exploded inside his mind like a raging torrent. Memories flooded in like a fast-forwarding film: faces, places, pain, fear. It lasted only a few seconds, yet it felt as though he had lived an entire lifetime in a single instant.
Now he understood everything. The owner of this body was named "Kurtz," a simple servant to a noble in the Goa Kingdom. Everything that happened stemmed from a trivial incident: he had accidentally broken an expensive vase on the second floor. The enraged noble threw him into prison immediately and ordered the guards to torture him daily without mercy. Sometimes, the noble himself would come to sit and watch the torture, as if it were a form of entertainment.
Kurtz had endured three months in this hell—beatings, whipping, and starvation—until he could no longer bear it. After the final torture session, he bit his tongue with all his strength and took his own life, choosing death over continuing that suffering.
Kyle slowly felt his body. He only sensed intense hunger, but no real pain or open wounds. It seemed the system had automatically healed all the body's injuries the moment he arrived, leaving him with a renewed sense of strength despite the body's original weakness. He stood up slowly, stretching his muscles and taking a deep breath, then recalled everything he knew about the Goa Kingdom from the stories he had read before.
Although it had initially appeared as just a small kingdom connected to Luffy, Ace, and Sabo, the Celestial Dragons had personally visited it during that time. Kyle would never believe that such a simple kingdom didn't hide dangerous secrets or buried treasures.
"What a bunch of fools… those World Nobles come to a small country like this just out of curiosity? There's definitely a huge secret here. I'll uncover it myself—and make it my first weapon in this world."
As he thought about his future plans, Kyle looked outside the cell through the rusty iron bars. A sly smile appeared on his face as he easily activated the Flying Thunder God Technique. He picked up a small stone, quickly marked it with the technique, and threw it beyond the bars into the dark corridor. In the blink of an eye, he vanished from his spot and reappeared outside the cell entirely.
"Hey, you! H-how did you get out of there?!"
A prisoner from the adjacent cell shouted in shock, his eyes wide. Soon, voices erupted from the other cells like a storm:
"Isn't that the boy who gets tortured every day? How did he escape?!"
"That's him! They say he offended a noble and was beaten daily… I thought he'd definitely die!"
Kyle ignored their chatter completely, his face cold and expressionless. He kicked another stone marked with the technique, then vanished again before everyone's eyes, leaving behind stunned silence.
"Who's there?!"
At that moment, the guards at the main prison gate spotted him in his torn gray prison clothes. They immediately rushed toward him, their faces filled with shock and anger. Despite their disbelief at his impossible escape, their professional instincts drove them to attack without hesitation.
Kyle cast them a brief glance. His current body was still weak and lacked sufficient energy, but he didn't hesitate.
"To defeat them, there's no choice but…"
He forcefully activated the Eight Gates.
"Gate of Opening (Kai Mon)… open!"
"Gate of Rest (Kyu Mon)… open!"
BOOOOM!
A powerful, visible aura burst around Kyle's body, shaking the very air itself. The charging guards suddenly stopped in their tracks, gripped by an instinctive sense of danger that made them hesitate for a moment.
Kyle felt a wild, explosive power surging through his veins.
A wide, confident smile spread across his face. With immense strength in his legs, he dashed forward at lightning speed...
