One Piece : Prince of Charlotte Family

In the first half of the Grand Line, there was a misty, sunless sea.

A massive eagle with white feathers, Finley, flew high in the sky, carrying a silver-haired figure.

It patrolled back and forth in this sea area.

This was the legendary "Magic Triangle."

It was surrounded by black mist all year round, so dark that the sun couldn't shine through.

It was said that many ships got lost here every year and couldn't find their way out.

Occasionally, one or two old, dilapidated ghost ships could be seen drifting in the area, adding an eerie feeling to the already creepy sea.

"Yo ho ho ho ~~~ Yo ho ho ho ~~~"

"Yo ho ho ho ~~~ Yo ho ho ho ~~~"

"Binks' fine wine~~~"

Suddenly, a haunting song echoed from the depths of the dark sea.

Some people couldn't help but get up, feeling a chill.

"The musician of the Rumba Pirates, 'Soul King' Brook... is this finally him?"

Looking down at the pirate flag hanging on one of the old ghost ships drifting aimlessly, Wilhelm, sitting on Finley's back, noticed the ship. He had been flying over the sea for three days, searching, when he saw the ship full of strange "skeletons" dancing around.

His eyes flashed with recognition.

Three days ago, he had crossed the Red Line and didn't stop there.

Instead, he went straight through the Sabaody Archipelago and came to this Magic Triangle.

He had been searching the area for three full days.

Finally, he had found the "Soul King" Brook, who had eaten the Underworld Devil Fruit.

The next moment, Wilhelm's pupils flashed, and he disappeared from Finley's back in an instant.

He flew directly toward the Rumba Pirates' ship. The ship was full of holes and pits, its rudder damaged and unable to steer.

On the broken deck, a skeleton wearing a tuxedo with an afro leaned against the side of the ship.

He was humming "Binks' Wine," a popular song loved by pirates in this sea.

But suddenly, everything in front of him became blurry.

Out of nowhere, a silver-haired figure appeared before him.

Brook, with his eerie skeletal grin, stared at the handsome young man and said, "Eh?"

"Flying Blade and Blood Claw!" Wilhelm's face darkened.

He wasn't interested in talking to Brook. He attacked immediately.

"Hoo--" He turned his fingers into sharp claws and lunged forward.

The beast-like claws, incredibly sharp, sliced through the air with lightning speed.

Five blood-red claw strikes tore through Brook's fragile, skeleton body in an instant.

"Boom..." A large part of the ship's side was ripped apart.

Deep, terrifying claw marks were left behind.

"Thump..."

A pile of broken skeletons fell to the deck, crashing down in a heap.

"Wait, I'm not a ghost, please don't kill me!" Brook, or rather his skull, shouted, desperate as the sudden attack left him immobilized.

"Oh? It's destroyed like this, but it's not really dead yet?" Charlotte Wilhelm raised an eyebrow in surprise.

With a grin, he bared his gorgeous, sharp teeth.

"The Underworld Fruit's power isn't meant for you!" Without hesitation, he pierced Brook's skull in an instant.

The skeletons shattered completely into dust.

"Ability transfer!"

Wilhelm's eyes glowed with bright blue light.

A strange glow enveloped the blade of his sword, Natural Fang.

A delicate blue gemstone on the sword's hilt shined brightly.

"Did you make it?"

Looking at the unchanged blade of Natural Fang, Wilhelm wasn't disappointed. Instead, he chuckled in satisfaction.

Earlier, the Paramecia Healing Fruit had affected the sword itself.

Now, he had eaten the Paramecia Baran Baran No Mi, which had transformed the gemstone on the sword's hilt into an unbreakable, indestructible gem.

From this moment, the true healing sword, Natural Teeth, was born.

Perfection had been achieved!

"With this, the true Natural Teeth is almost complete..."

Wilhelm gently caressed the beautifully patterned and extremely sharp blade of Natural Fang, speaking to himself: "Theoretically, if the Underworld Fruit's ability is fully developed, it could open a path to the Underworld, even to the very world of souls."

Cold air, and even souls, could be controlled!

"If it's combined with the Healing Fruit's ability, it might be possible to truly bring someone back to life!"

"But that's just theoretical..."

In his vision, if the Healing Fruit could be perfectly combined with the Yomi Yomi no Mi Fruit's powers, bringing the dead back to life might not be impossible.

But Wilhelm wasn't sure if it would work.

To fully master this unique sword and perfect its Devil Fruit abilities, he would need more time for testing and experimentation.

Furthermore, the Yomi Yomi no Mi Fruit had the ability to restrain the Soul Fruit power of that woman, Charlotte Linlin, which would be a huge advantage when he faced BIG-MOM in the future.

"Next, how much power this Tenseiga can unleash depends on destiny!"

"Whoosh!"

In the next moment, Wilhelm vanished from the ghost ship.

When he reappeared, he was already back on Finley, who was about to descend from the sky.

"Let's go, our next destination is Asuka Island!"

He returned the Natural Teeth to its sheath and sat on Finley's back, giving a direct command.

"Hey—" Finley, now a giant eagle, responded with excitement.

With a powerful flap of its wings, a strong gust of wind was kicked up as it flew toward the distant sea.

"The legendary cursed demon sword... don't let me down!"
