Sexy Isekai: One Piece Most Wanted-Chapter 56 - 54: The Nun of Whiskey Peak

When the ad appeared, Mandi thought it was a joke.

Tired of your boring life? Want adventure, freedom, and power?

Click "Yes" to apply for our Smart Isekai Experience.

No refunds.

Albert had laughed beside her on the couch, his arm draped over her shoulder. "You’re really gonna click that, babe?"

"Hell yes," she said. "What’s the worst that could happen?"

Now she knew.

Because when she opened her eyes again, the smell of gunpowder and sea salt filled her nose, and a nun’s veil slid off her head as she sat up in a dusty pew inside an old chapel.

The mirror across from her showed a stranger.

A tall, muscular woman with deep brown skin and pink hair tied into short twin-tails. A diamond-pattern dress hugged her broad shoulders and heavy curves, and three green flowers pinned at her chest looked absurdly delicate compared to her physique. She blinked—and the reflection blinked back.

Then the memories hit her like a flood: Miss Monday. Baroque Works. Whiskey Peak. Mr. 8. The Grand Line.

She groaned, clutching her head. "You’ve got to be kidding me."

But when she tried to stand, the world tilted—and a low, gentle hum stirred inside her body. Not a devil fruit. Something else. A vibration of potential and power that made her skin tingle.

Two quirks detected, a voice echoed faintly in her head—cold and mechanical, like the system interface from a dream.

[Overhaul][Creation: Creati]Initialization complete.

Mandi froze. Her pulse quickened. She clenched her fist and felt the air around her respond, bending slightly to her will. She could sense the structure of things—the wood of the pews, the fibers of her dress, the cells in her muscles.

"Okay," she whispered slowly, lips curling into a grin. "Let’s make this work."

The Nun of Whiskey Peak

It didn’t take long to learn her surroundings.

Whiskey Peak was a pretty little nightmare—rows of stone houses curling along a jagged coast, every window glowing warm with welcome and deceit. The people smiled too much. The laughter went on too long.

Mandi—now "Sister Monday"—played her part.

She wrapped her veil tight, adjusted her collar, and let her voice rise into the gentle, high-pitched lilt of an innocent young nun."Oh dear, weary travelers, please—come rest. Whiskey Peak welcomes all who brave the Grand Line!"

Her soft voice and calm demeanor disarmed suspicion, and even her partner, Mr. 8, believed her act completely. He had no idea that beneath the loose sleeves of her habit were biceps thick as iron cables—or that she could unmake a human body with a touch.

By day, she served tea to bounty hunters. By night, she modified herself in secret, using Overhaul to tune her muscles and ligaments, optimizing her stamina and control. Every nerve she rewired made her feel closer to mastery, closer to balance. She could sense the raw material of the world—and her Creation quirk whispered ideas at the edges of her thoughts: schematics, blueprints, possibilities.

The old her—the Mandi who’d dreamed of adventure—was gone. What remained was the woman who would survive.

And maybe, just maybe, find Albert again.

The Arrival of the Spade Pirates

The day started like any other. Mandi was arranging flowers at the chapel’s altar when the bell at the port rang twice—a signal that a new ship had arrived.

She walked to the window and froze.

The sails were black, emblazoned with a single flaming spade.

She didn’t need to know the future to understand what that meant.

"Portgas D. Ace," she murmured.

Mr. 8 burst through the chapel doors, out of breath and grinning. "Sister Monday! Big catch today! The Spade Pirates just docked—Captain Ace himself! Headquarters will pay handsomely if we deliver him!"

Mandi folded her hands piously. "Oh dear... how wonderful."But inside, her mind was spinning.

Ace was no fool—and no ordinary pirate. His Logia fire power would reduce the island to ash if provoked. Baroque Works was about to bite off far more than it could chew.

As Mr. 8 left to organize the "welcome party," Mandi stayed behind, slipping the veil from her head. Her reflection in the chapel window was serene, but her eyes were hard.

"Guess I’m done hiding."

The Trap

By nightfall, Whiskey Peak was glowing like a festival. Music echoed through the streets, and barrels of wine lined the square. The "good people" of the island raised their mugs high, all smiles and honeyed words.

Ace and his crew—loud, confident, unbothered—accepted the hospitality with easy grace. Mandi watched from a distance, veil pulled low, pretending to pour drinks for the guests.

She saw the moment it was supposed to happen—the instant when the poisoned wine was meant to be served.

She moved first.

In one smooth motion, she upended the tray, sending cups flying and liquid spilling across the floor. The crowd gasped.

"Forgive me, brothers and sisters!" she squeaked in her soft, childish voice. "But I simply cannot allow this! The wine—oh, it’s tainted!" 𝒻𝘳𝘦𝘦𝘸ℯ𝒷𝘯𝘰𝑣ℯ𝑙.𝘤𝑜𝘮

Dozens of heads whipped toward her. Mr. 8’s jaw dropped. "Sister Monday, what are you—"

But Ace had already raised his nose, sniffed the air, and smirked. "She’s right. Smells like almonds. Poison."

The air ignited around his shoulders before the nearest agent could blink.The explosion tore through the square, sending men flying.

Baroque Works’ cover shattered instantly. Swords flashed, bullets rang out, and Ace stood in the middle of it all, laughing as fire bloomed from his hands.

"Thanks for the warning, Sister," he called, grinning through the smoke.

Mandi dropped the act completely, tearing the habit off her shoulders as she charged into the fray. Her muscles rippled under the moonlight, her pink twin-tails whipping behind her. The bounty hunters barely had time to register the transformation before she slammed her fist into the ground, Overhauling the cobblestone beneath their feet into a jagged wall that sent them scattering.

"Never did like poison," she said, voice deeper now, her true tone emerging.

Mr. 8 gaped from a distance, too stunned to move. "Miss Monday! What in the hell—"

"Quitting," she said simply, and punched him into a crate.

The battle was short. Ace’s flames swept through the streets, his crew overwhelming what few hunters remained. Whiskey Peak burned, the sky above painted in orange and black.

An Offer at Dawn

By sunrise, the island was quiet again. Charred, smoking, but quiet.

Mandi stood at the port, watching the tide pull away the ashes. She hadn’t expected the guilt that gnawed at her stomach. She had lived among these people for weeks, laughed with them, shared meals. But they’d chosen their path.

A shadow fell across her shoulder.

"Didn’t expect a nun to throw punches like that," Ace said lightly, hands in his pockets. His smile was crooked, amused. "You one of Crocodile’s people?"

"Was," she said. "Not anymore."

He raised an eyebrow. "So why help us?"

Mandi hesitated. The truth was too complicated to explain: because I’ve already died once, because this world isn’t mine, because somewhere out there, Albert’s alive, and I’ll find him no matter what.

So she simply said, "Because I pick my battles wisely. You’re the kind of man people should bet on."

Ace studied her, then shrugged. "Fair enough. We’re short a few hands, and I could use someone who punches like you. You in?"

Mandi smiled faintly, brushing ash from her sleeve. "Depends on the benefits."

He laughed, a bright, carefree sound that carried across the harbor. "You’ll fit right in."

The First Voyage

The Spade Pirates set sail an hour later, their ship cutting cleanly through the foam. Mandi stood at the railing in her new outfit—a sleeveless black crop-top, white pants, and a pink bandana keeping her twin-tails in check. She’d left the habit behind for good.

The sea wind felt alive on her skin. Freedom. Real, dangerous freedom.

Ace sauntered up beside her, his hat tilted low. "So, Sister Monday. Or should I say...?"

"Mandi," she said, turning her gaze to the horizon. "Just Mandi."

"Alright, Mandi," he said with that easy grin. "Welcome to the Spade Pirates."

He walked off to bark orders, leaving her with her thoughts—and her reflection in the waves below.

She lifted her hand, watching faint golden light shimmer around her fingertips as she summoned her second quirk’s energy. Creation.

"Let’s see if it still works."

The air rippled, and a small metallic object formed in her palm—a charm shaped like a spade, gleaming softly. She smiled.

So both quirks had come with her. Overhaul to destroy and rebuild. Creation to manifest and invent. Two powers from two worlds, balanced in one body.

She clenched her fist, the charm dissolving back into light.

"Smart Isekai Ad," she murmured to the wind. "Guess it worked."

The ship rolled gently underfoot, sunlight spilling across the deck. Somewhere in this vast ocean, Albert was alive. Maybe a pirate, maybe a ghost, maybe a monster—but alive.

She would find him. She would make this second life matter.And when they met again, she’d make damn sure he recognized her.

Mandi tilted her head back, letting the sun burn across her face.

Behind her, Ace shouted, "Oi! Sister Monday! Hope you’re ready for training—on this ship, everyone learns to fight fire!"

She grinned, flexing her fingers. "Let’s see if fire can handle pressure."

As the Spade Pirates’ laughter echoed into the horizon, Mandi—the nun, the warrior, the woman from another world—finally began to feel at home.
