One Piece : Prince of Charlotte Family

"Clatter..."

The next morning, the sea breeze blew gently.

A medium-sized pirate warship, armed with plenty of cannons, was slowly sailing across the calm sea.

Onboard were the three sisters—Smoothie, Strong, and Cinnamon.

They had been ordered by Wilhelm to wake up early and start their first day of training.

From now on, every morning, they had to wake up early and practice swordsmanship for over two hours before they could stop to rest and enjoy a delicious breakfast.

After breakfast, they were allowed a half-hour break.

Then... it was back to training.

Faced with the strict Wilhelm, the sisters were frustrated and complained nonstop.

But this was a bet they had agreed to with complete confidence, and now they had to honor it. Wilhelm, being their dear younger brother, had no intention of letting them off the hook.

After two hours of training, the sisters were already drenched in sweat.

However, since Wilhelm trained alongside them, encouraging them in his own way, none of them wanted to lose face in front of their younger brother. No one tried to slack off or cheat.

"This is the 'Six Powers' training method, Sister Smoothie. You can learn it next!"

After finishing breakfast, Wilhelm held up a small notebook, no larger than the palm of his hand, and tossed it to Smoothie and her sisters.

The notebook was loot they had taken from the Marine Vice Admiral Onigumo the day before.

Inside, it detailed not only the Six Powers training techniques but also the Onigumo's personal notes and insights on mastering them.

"Hey, Wilhelm…"

As they listened to the training plan Wilhelm had prepared, the three sisters looked at their brother in surprise.

"You're asking us to learn the Marines' Moonwalk?"

"The 'Six Powers' is an advanced martial arts system developed by the World Government after centuries of refinement," Wilhelm explained with a shrug.

"Shave, Finger Pistol, Iron Body, Moonwalk, Tempest Kick, and Paper Arts—they're all impressive techniques. You don't have to learn all of them if you're not interested, but you must master Moonwalk!"

To Wilhelm, skills like Shave, Finger Pistol, Moonwalk, and Tempest Kick were essential.

Over the years of practicing alone, Wilhelm had relied on his incredible talent and monstrous physical strength. He had also learned from Katakuri and others who had fought against Marine masters of the "Six Powers."

Through observation, simulation, and repeated attempts, he had smoothly mastered these techniques one by one.

For Wilhelm, skills like Paper Arts and Iron Body felt unnecessary. With his naturally tough body—like copper skin and iron bones—he was already immune to most weapons and bullets.

Coupled with his awakened Observation Haki, these techniques seemed redundant. However, thanks to his talent and physical strength, mastering them would still be easy if he chose to.

What truly fascinated him were advanced techniques like the "Six King Gun" and the special ability known as "Life Return."

The Six King Gun (Rokuogan) was an attack technique capable of unleashing devastating shockwaves.

Life Return, on the other hand, allowed total control over one's body, including hair and internal organs. By focusing one's consciousness, it enabled precise control of any part of the body.

Take Vice Admiral Onigumo, for example. Using Life Return, he could manipulate his hair as though it were additional arms, wielding multiple swords at once to perform an unpredictable eight-sword style. This made him incredibly dangerous in battle, catching opponents off guard.

When Wilhelm found Onigumo's wet notebook among his remains yesterday, he carefully dried it and read through it entirely. He had already memorized everything about Life Return. However, mastering such a skill would still require time, patience, and continuous practice.

He believed that Life Return was the ultimate technique for controlling muscles, organs, and overall bodily functions. If he could perfect it, it would significantly enhance his strength.

"In this world, the sea covers more than 90% of the surface, except for the Red Line," Wilhelm explained as he watched his sisters, who didn't seem to take "Moonwalk" seriously.

"As pirates, we often fight near or on the sea. If any of us with Devil Fruit powers accidentally falls into the water during a battle, we'll be helpless, giving our enemies a chance to strike!"

He continued patiently, "Don't underestimate this skill. Mastering Moonwalk allows you to stay in the air briefly, giving you an advantage in aerial combat and serving as a critical life-saving technique in emergencies."

Then Wilhelm turned to Smoothie and added, "And as members of the Longleg Tribe, your leg strength is far superior to ordinary humans. Learning Moonwalk shouldn't be too hard for you!"

Having already mastered Moonwalk himself, Wilhelm understood both the strength of his sisters and the natural advantages of the Longleg Tribe. He was confident they could master the skill with consistent effort. Though reaching a true mastery would depend on their talent and dedication.

"Really?"

"So that's how it works!"

The three Smoothie sisters finally understood.

They now realized how useful Moonwalk could be. For Longleg women like them, practicing it wouldn't be overly difficult.

Snamon, in particular, was deeply impressed. As a Paramecia Devil Fruit user with the Squeeze-Squeeze Fruit, she had a strong understanding of how dangerous the sea could be for Devil Fruit users. Her eyes lit up with determination.

Make a decision to master a skill like Moonwalk.

"Of course, as members of the Longleg Tribe, skills like Shave and Tempest Kick would suit you well. It's up to you whether you learn them or not..."

Wilhelm shrugged and continued, "In the end, the Six Powers are the result of countless strong individuals' hard work. After hundreds of years of use in battle, they've been refined and perfected through experience..."

He didn't see the "Six Styles" as some unbeatable martial arts technique, but believed in studying and understanding them.

Not to mention forcing the three Smoothie sisters to master them, but he did think they had value. Even if they didn't want to invest too much energy in learning, they could absorb its essence and incorporate it into their swordsmanship.

"Sticking to the paths of the past without innovation or exploration won't help you carve your own path. It's important to learn from others, but also push forward with your own ideas."

Just then, a newsbird flew past.

Wilhelm raised his hand and flicked a coin.

The coin landed perfectly on the money pouch hanging from the bird's neck, grabbing the newly delivered newspaper.

Several bounty posters clipped to the newspaper followed, drawing attention.

"Eh? A Marine reward?"

"Wilhelm's picture? When did those Marines take it?"

"Two hundred million Berries? Tsk, those guys know everything—even about the 'Trembling Nobleman'!"

At the top of the reward list, Wilhelm's silver-haired figure was unmistakable. His bounty was clearly listed: Charlotte Wilhelm, unknown abilities, bounty of 200 million Berries, dead or alive.

Below him were his three sisters—Smoothie, Strong, and Snamon—with individual bounties of 30 million Berries each.
