In the world of One Piece, the existence of Devil Fruits is widely recognized and accepted.
Finn, with his own warship, brought Nami, Tashigi, Robin, Vivi, and Kalifa aboard the grand vessel. The fact that such a massive ship sailed without anyone operating it only reinforced Finn's story about his "Devil Fruit powers."
Some Paramecia abilities, like the Lick-Lick Fruit or the Biscuit-Biscuit Fruit, allow their users to create warships. However, these still require large crews to operate. Finn's fabricated "Devil Fruit for Summoning Warships" was unique in that the ship could be operated without any crew at all.
Of course, the supreme warship he received from the system could be driven automatically, though it could still be operated manually if necessary. If Finn ever found a good helmsman, he might consider switching to manual control.
As they traveled, Garp's warship led the way, while Finn's luxurious vessel followed behind, heading toward Enies Lobby.
"Wow, Master! Your Devil Fruit ability is amazing! This ship is like a floating castle!" Nami exclaimed, running barefoot across the massive deck.
The deck was enormous, almost endless, making it impossible to worry about falling off. At some point, Nami had changed into a bikini and, after sprinting happily for a while, dove into the large pool on the deck with a splash.
Tashigi, wearing a short-sleeved T-shirt, was off to the side practicing her swordplay, while Princess Vivi emerged from the cabin, also dressed in a bikini, and joined Nami in the pool.
Kalifa, the busiest of the group, was holding a stack of blueprints, meticulously inspecting various facilities on the ship. As the ship's secretary, it was essential for her to know the layout inside and out, so she could execute Finn's commands at a moment's notice. She was also making careful notes for herself—perhaps for her "undercover mission"...
Under a parasol, Finn lounged on a chair, wearing nothing but shorts and flip-flops, holding a Michelin three-star ice cream and watching the scene unfold with a satisfied smile.
Life was good.
Just then, a pair of hands landed on his shoulders. Without even looking, Finn knew, thanks to his Observation Haki, that it was Robin.
"Miss Robin, what can I do for you?" he asked casually, not turning around.
"Can't I just give you a massage, you stinky little brother?" Robin teased as she started to knead his shoulders.
"Oh? My big sister being so nice to me? You must want something," Finn said with a knowing smile.
Robin's tone became more serious, though not accusatory. "Finn, you lied to me, didn't you?"
There was no anger in her voice, just curiosity. Robin had been around long enough to gauge someone's true nature, and after traveling with Finn, she had a good sense of who he was.
"Who said I lied to you?" Finn replied calmly. He noticed Robin continued to massage him gently, a sign that she wasn't truly upset, just looking for answers.
Robin leaned in slightly, her voice soft but playful. "The last time we made a bet, you told me you weren't a Devil Fruit user."
"Oh, that," Finn chuckled. He patted her hand lightly, then stood up and walked toward the pool. "Miss Robin, I didn't lie. I'm not a Devil Fruit user. Watch."
With that, he jumped into the pool with a splash, drenching Nami and Vivi in the process.
"Master, be careful!" Nami shouted, panicking. "You'll sink to the bottom if you're a Devil Fruit user!"
She quickly swam over to grab Finn, and Vivi followed suit. "Benefactor, this is dangerous! You shouldn't be swimming if you have Devil Fruit powers!" Vivi added in concern.
Finn blinked, confused. He had jumped in to prove he could swim, but now his arms were being tightly held, ruining his demonstration.
"Relax, everyone. I'm not a Devil Fruit user," Finn said, pulling his arms free.
To further prove his point, he performed a backstroke, followed by an elegant butterfly stroke, then dove underwater for good measure.
When he resurfaced, he hopped out of the pool and stood beside Robin, arms crossed. "Satisfied?" he asked with a grin, leaning a hand on her shoulder and winking.
Robin, slightly embarrassed by her misunderstanding, smiled wryly. "But... didn't you say this warship was summoned by a Devil Fruit ability?"
Nami, curious as ever, chimed in. "Yeah, you did say that, Master."
Vivi, though silent, looked intently at Finn, awaiting his explanation.
Finn shrugged casually. "It's a little more complicated than that. It's not exactly a Devil Fruit ability—more like an ancient power I inherited. Maybe I have the genes of the ancient gods. Who knows?" He waved his hand dismissively. "Anyway, now that you all know my secret, don't you think it's time you shared one of yours with me?"
Robin raised an eyebrow, surprised. "You want to know a girl's secret?"
"Well, I misunderstood you, stinky brother, so I suppose I owe you something in return," Robin teased with a playful smirk.
"Master," Nami added with a grin, "I'll share my secret with you too."
Vivi giggled softly. "Benefactor, if it's only fair, I suppose I could share one with you as well."
Finn chuckled, leaning back in his chair. "Alright, I'm listening."
After the lighthearted moment passed, Finn glanced at Robin again. "Want to go for a swim?"
Robin shook her head with a smile. "I can't. I'm a real Devil Fruit user, remember?"
"Ah, that's right. But who says Devil Fruit users can't have fun in the water?" Before she could protest, Finn lifted Robin and threw her into the pool with a splash.
"Stinky brother!" Robin laughed as she emerged from the water, not as upset as she pretended to be.
For the next few hours or minutes, Finn's life on the ship was nothing short of bliss.
Eventually, the warship arrived at Enies Lobby.
