One Piece: Rising to Power as a Warlord of the Sea

The spring of the year 1515 in the Sea Circle Era, fifty miles north of the Revolutionary Army's headquarters on Baldigo Island, lies Beast Island.

"Hey, hey!"

"Up and down, up and down!"

"Ninety-six!"

"Ninety-seven!"

"Ninety-eight!"

"Ninety-nine!"

"One hundred!"

"Ah, that felt great! Finally done!"

With a heartfelt sigh of relief, a black-haired boy lay sprawled on the ground, arms and legs outstretched toward the sky. In the sunlight, his handsome face radiated with charm, making him hard to resist.

"Yikes, I'm exhausted!"

Next to him lay a plump, black-and-white panda, also sprawled out, tilting its head and sticking out its tongue, looking utterly despondent.

Around the boy and the panda, a massive white tiger was furiously practicing combat skills, swinging its claws with vigor. On the ground lay a small book titled Dragon Subduing Fist, while to the side, a muscular golden monkey was diligently practicing swordsmanship, wielding a large blade that was as tall as itself, with another book beside it labeled Dugu Nine Swords.

The boy's name was Natsu, full name Monkey D. Natsu. He was the son of the world's most notorious criminal and Revolutionary Army leader, Dragon, and the grandson of the Navy hero, Garp. Natsu was Luffy's biological brother, and at sixteen years old, he had been taken by Dragon to the Revolutionary Army when Luffy was just three. Since then, he had been operating under a golden mask, with only a few key figures in the Revolutionary Army aware of his true identity.

He was known as the Golden Lightning of the Revolutionary Army ⚡ for his incredible speed!

At that time, a book titled Revolutionary Book emerged, its ideas becoming the core philosophy of the Revolutionary Army, spreading across the world.

Concepts like peace, freedom, equality, democracy, and harmony became aspirations for people everywhere. A wave of resistance against the tyrannical Celestial Dragons surged in the hearts of the people, and the World Government was constantly seeking to eliminate the Revolutionary Army.

Yet, they had never succeeded!

At this time, Luffy was only twelve years old and had already met the person who would change his fate, Red-Haired Shanks. He had also consumed a special, divine fruit, the Paramecia-type Gomu Gomu no Mi, also referred to as the Mythical Zoan-type Nika Fruit. He was likely busy training hard with Ace.

"I can't believe it's already been sixteen years since I came to this world! Time flies!" Natsu got up and sat cross-legged on the ground, clenching his powerful fists. In his mind, a panel appeared—yes, Natsu was a reincarnator and possessed a "golden finger" ability. The panda, whom he named Kumo, was a reward for completing his first mission—a reminder of his home.

Ding! Congratulations, host, on doubling the completion of your daily tasks! In accordance with the "Self-Reflection: I Examine Myself Three Times a Day!" survival law, you have earned one lottery opportunity! Task Points +10!

A system voice echoed in his mind, and Natsu couldn't help but smile with satisfaction. "I'm so great!" ●´৺'●●´৺`●●´৺'●

He praised himself for sticking to this routine for ten whole years. Since the age of six, Natsu had been training using the Saitama method, diligently pushing himself day in and day out. With his past life's experience studying the survival laws, he fully embraced the habits of diligence, effort, and virtue.

"I examine myself three times a day," was his mantra—he trained hard every day, exceeding his system tasks, which helped him achieve his current reliable strength and build a set of eight-pack abs.

Looking at the eight accumulated lottery chances in his mind, Natsu felt overjoyed. If he could get just two more chances, he could do a ten-pull. Based on years of experience, he knew that a ten-pull would yield something good—at least a famous sword, powerful skills, or a devil fruit of equivalent value.

"Gululu~ Gululu~"

"Boss, I'm hungry~ ฅ(̳•◡•̳)ฅ"

The panda, Kumo, suddenly sat up, patting its round belly and looking at Natsu with pitiful eyes.

"Alright, I'm hungry too. Let's head to the beach! By the way, I haven't tried the Sea King yet." ٩(ˊᗜˋ)و

Natsu did a flip and stood up, a smile spreading across his face. Ever since he arrived on this island, he had become the king with his growing power. The local creatures had mostly been consumed, and there were no real challenges left.

Only the boundless sea ahead promised an exciting adventure!

"Komi Kene, Komi Shiro, let's eat first and then train later."

Due to Natsu's beast-taming talent, Komi Kene and Komi Shiro were the most gifted beasts on the island. After numerous attempts at reasoning with them, they became his tamed beasts. When Natsu went on missions for the Revolutionary Army, Kumo acted as the leader of their group, running wild on the island. But in front of Natsu, they always behaved like good children.

Natsu called to the two beasts who were working hard to train and then vanished from his spot, his speed astonishing.

As for why he ran so fast, Natsu often said, "He enjoys listening to the sound of the wind."

Following closely was the pudgy silhouette of Kumo, a surprisingly agile panda that had also learned the technique of super speed.

"Whoosh~ Whoosh~ Whoosh~"

The sea breeze howled, and the surging waves grew higher, crashing against the shore. Natsu and Kumo stood quietly at the water's edge, activating their Observation Haki to its maximum extent, constantly seeking targets in the ocean.

"Got it!"

Finally, Natsu's gaze locked onto a direction, and his body shot forward, leaping into the sea like a bolt of lightning.

"Boom! Bang!"

With a resounding clash from below the surface, blood spread across the water, staining the surrounding sea red. Soon, bubbles began to rise, and from the rolling waters emerged a massive black shadow, swaying unsteadily. One of its eyes was now bloodied, bleeding profusely.

"Drip! Drip! Drip!"

"Wow, it's huge! Is this the Sea King?"

"It should be delicious! (〃∇〃)"

Kumo gasped, its eyes widening as drool trickled down its chin.

In the water was a sea creature resembling a bull with a fish's tail, nearly a hundred meters long, glaring with lantern-sized eyes at Natsu. This human boy had nearly knocked it out with a single punch.

"Roar!"

"The skin is so tough; one punch didn't take it down!" Natsu licked his lips, a grin spreading across his face as he excitedly stared at the giant sea beast.

"Boss, boss, take it down! Let's eat meat! Meat!"

On the shore, Kumo waved its fists, excitedly shouting encouragement. It was a true meat lover; aside from its favorite bamboo, delicious meat was its second-best food.

"Tai Chi: Crushing Force!"

Natsu unleashed a punch, the terrifying force creating waves that crashed against the shoreline, shaking the surrounding space. The powerful impact struck the sea creature's body directly.

"Riiiiip! Whoosh!"

The sea shook again, and with a loud bang, the enormous creature flew out of the water, crashing down onto the island. The formidable Sea King was lifeless after a single blow.

Sea King: "I just stepped out for a meal; why am I being attacked?"｡ﾟ(ﾟ´(00)`ﾟ)ﾟ｡

Natsu: "Oh beast, it seems we're just fated to meet!" ╭︎(˙º˙)╯︎

An hour later, a mouthwatering aroma wafted through the air at the shore as Natsu and Kumo used their Illusionary Hands to quickly devour a mound of roasted meat, leaving a pile of bones beside them.
