One Piece: The Strongest Female Pirate Crews

********************************************************************

Late at night.

Marine Headquarters, Marineford.

"I will end the Pirate Era during my time."

"The entire ocean should be under the rule of the World Government—peaceful and prosperous."

Sengoku, who had recently been promoted to Fleet Admiral, stared at the world map with determination.

"Fleet Admiral Sengoku, we have an emergency!"

A panicked marine burst into the room. "Holy Land Mariejois has been invaded!"

Sengoku's face darkened. "What did you say? The Holy Land? Invaded? That's impossible!"

"Just an hour ago, an enemy infiltrated Pangaea Castle, freed all the slaves, and set the place on fire."

Sengoku's eyes widened.

"Summon all high-ranking officers immediately. What's the status of Mariejois?"

"We don't have full details yet."

As Sengoku hurried through the base, his heart pounded. This was an unprecedented disaster—something that hadn't happened in centuries. He roared, "What about the marine forces stationed at the Holy Land? Where is Vice Admiral Gion? Get in contact with her immediately!"

"We just spoke to the marine unit at the Holy Land. Vice Admiral Gion went after the enemy on her own, and we haven't heard back from her yet."

"Who is the enemy?" Sengoku's tone was filled with fury.

No matter who it was...

They would pay.

"We haven't identified the leader yet, but one of their accomplices is a Fish-Man."

"Find them! Right now! They must not escape!"

Sengoku's angry shouts echoed throughout Marineford.

Meanwhile, across the dark ocean...

A ship plunged down from the Red Line's river, crashing into the sea, sending up a huge splash of water.

The water soaked the three sisters huddled at the bow of the ship.

"We've escaped from hell."

The three Boa sisters looked back at the towering Red Line, a mixture of hatred and relief in their eyes.

"The real challenge starts now."

The boy steering the ship, Kuke, reminded the sisters, who were still crying with relief.

They turned their gazes toward him.

Hancock and her sisters looked at Kuke with gratitude.

At the darkest point in their lives, a ray of hope had broken through, saving them from their prison and dragging them out of hell.

"So this is Boa Hancock before she became the Pirate Empress?" Kuke thought as he watched the shy and awkward Hancock. He found it amusing.

The fierce, dominant woman she would become was nowhere to be seen yet.

She still had a youthful innocence about her.

But even now, her stunning beauty was undeniable.

"Why are you staring at me?"

Hancock felt her face grow hot under Kuke's gaze, and she quickly looked away, unable to meet his eyes.

"What are your plans now? If you come with me, you'll likely be hunted by the World Government too," Kuke asked, looking at the three sisters.

Sixteen-year-old Hancock, along with her two younger sisters, stared out at the endless ocean, lost for a moment.

They had no idea where to go.

Home? Returning to Amazon Lily would be difficult. If their identities were discovered, it could bring disaster to their homeland.

They were stuck with no options.

Biting her lip, Hancock looked at Kuke, her eyes filled with hope. "Can we... come with you?"

At this moment, the person they trusted the most was the one who had saved them—Kuke.

"If you come with me, you'll have to be ready to fight against the entire world. Do you have the courage for that?" Kuke asked, his gaze serious as he looked into their eyes.

The two younger sisters, terrified of the World Government, clung to each other.

As the eldest, Hancock slowly stood up. "If you're willing to take on the world for us, how could we back down?"

The Empress was beginning to emerge.

At that moment, Hancock felt fortunate for her strength.

Even though they had been slaves, their situation had been better than most of the Celestial Dragons' slaves.

Almost all Celestial Dragons owned slaves.

Each had their own twisted preferences.

Some liked collecting pirate captains, others found joy in torturing their slaves. Some were obsessed with beauty, gathering women from every race.

As for the Celestial Dragon that owned Hancock and her sisters...

He didn't care for beauty, but he loved watching slaves fight each other to the death. To make it more entertaining, he would even feed his slaves Devil Fruits to boost their abilities.

Hancock had eaten the Love-Love Fruit, giving her decent combat power.

"Alright then, let's go." Kuke reached out his hand.

Hancock placed her delicate hand in his, her face flushing bright red.

But Kuke didn't notice—his attention was elsewhere, focused on the system.

He was a transmigrator.

And he had a system.

[Ding! Boa Hancock has joined your pirate crew. Combat Power +10,369, Charm +9]

[Ding! Boa Marigold has joined your pirate crew. Combat Power +2,314, Constitution +5]

[Ding! Boa Sandersonia has joined your pirate crew. Combat Power +2,523, Constitution +5]

The system tasked Kuke with building the strongest all-female pirate crew on the seas.

Each time a new member joined the crew, Kuke would receive a power boost equal to that member's combat strength.

As their strength grew, so did his.

At this moment, Kuke's total combat power was:

[Kuke: Combat Power 169,058]

"Boa Hancock is a future Warlord of the Sea, and her sisters are powerful too. They're still young, so their combat power will at least double in the future."

Whatever they gained...

Kuke gained as well.

Saving those slaves had been worth it.

Recruiting Hancock and her sisters wasn't a loss.

The rest would be pure profit.
