One Piece: My Crew is from Other World

After bidding farewell to Shimotsuki Koshiro, Ryuunosuke led the crew back to the Ship of the Gods.

"Captain... is it just me, or have we... suddenly gotten stronger?"

Najenda asked as she stepped onto the deck, her senses sharpened.

Ryuunosuke nodded. "You're not imagining it."

The glow around the crew was subtle but unmistakable—the result of the Glory Aura that had just been unlocked from the system's reward. The Heart of Eternity wasn't just a treasure; it was reshaping the power of their entire fleet.

"This is the strength of unity. A team power-up, granted through the system. Let's not waste the momentum."

He turned, eyes sharp. "We're heading for the New World. First stop—Pluto's wreckage."

With every rising storm, Ryuunosuke knew one truth remained constant—only strength brings freedom. And finding the remains of Pluto, one of the legendary Ancient Weapons, would serve two purposes: upgrade the Ship of the Gods and skyrocket their reputation.

"I understand, Captain," Najenda responded, then asked, "Are we taking the Calm Belt or going the Grand Line route?"

"We'll take the Grand Line. I want to pass through Fish-Man Island first."

He didn't elaborate, but there were still unresolved thoughts lingering beneath the sea.

Najenda passed along the order to Nojiko, and soon the entire crew was back in motion.

As the ship sliced through the currents, Ryuunosuke quietly approached Mario, who was, unsurprisingly, flirting with the princess from his squad.

"Mario, take me to the ship's core."

Even Mario, caught mid-blush, straightened up immediately.

"Right away, Captain!"

He pulled a green warp pipe from inside his coat and gestured for Ryuunosuke to follow.

Moments later, they emerged in the core chamber of the Ship of the Gods.

This room pulsed with power. It was the heart of the vessel, where the energy core hummed like a slumbering dragon. The same core that had reacted to Pure Gold was now being prepared for something even greater.

"Let's begin."

Ryuunosuke activated the system's item reward—Ship Spirit: Active Mode.

In an instant, a gentle light filled the chamber, and from it emerged a floating figure—a ship spirit, shaped like a glowing elf, delicate and ethereal.

But this wasn't just aesthetic magic—Ryuunosuke could feel the spark of life within her.

A true spirit. A sentient being.

"Can you understand me?" he asked carefully.

"Yes, Captain!" she replied, her voice soft yet clear—warm like the sea breeze.

Ryuunosuke raised a brow. "Impressive."

The Ship of the Gods now had a will. A guardian.

"You are the official spirit of this ship," he said. "From this moment forward, you'll manage its systems, monitor its structure, and protect its heart."

He then reached into his inventory and retrieved the Heart of Eternity—a stone pulsing with cosmic light.

"This... is your core. The key to awakening the full potential of this ship. Do you accept it?"

The spirit's eyes lit up. Her delicate hands reached forward reverently, and she took the Heart of Eternity like a divine offering.

Without another word, she floated to the center of the chamber and pressed the heart into the core's housing.

BOOM—

The entire chamber flared with radiant light as the Heart of Eternity sank into place.

The ship spirit dissolved into pure energy and fused with the Heart. A wave of force erupted, so intense it pushed Ryuunosuke back a step.

He instinctively reached for his Observation Haki, trying to scan the transformation.

But it was blocked.

"…Tch. I can't even peek into my own ship?"

He chuckled wryly, but he wasn't frustrated. He knew this was a good sign.

Whatever was happening inside… it was massive.

He called Mario back and returned to the deck.

Despite the core undergoing fusion, the Ship of the Gods continued to sail smoothly, cutting through the sea like a blade. There was no instability, no delay—just quiet, efficient progress.

The crew slowly adapted to their new surge in power. Some meditated. Others sparred. A few simply sat and let the energy soak into their bones.

By nightfall, Ryuunosuke retreated to his cabin.

There, he did what he always did between battles—restore and reflect.

The world was changing fast. The Dragon Hunter Pirates were evolving rapidly. And now, with the Heart of Eternity fused into their ship, they had stepped into territory no pirate crew had ever reached.

He had barely closed his eyes when—

Click.

The door creaked open.

He turned, instinctively alert.

A figure entered.

Akame.

She stood at the threshold, her presence quiet but purposeful.

Her red eyes locked with his.

"Akame? What are you—"

Before he could finish, she let her clothes slip off.

Ryuunosuke froze.

Her breathing was soft, warm. Her gaze unwavering.

He had always been immune to temptation—until now.

After their feelings were laid bare, after the emotional tension that had simmered for so long... now, there was no denying it.

"Brother Ryuunosuke," she whispered, stepping closer. "I know you're awake."

"But please… don't speak."

"I… I'm a little embarrassed."

Her voice trembled, yet her steps never stopped.

By the time she reached the bed, Ryuunosuke felt heat rushing through his body. His entire frame stiffened.

Literally.

Moments later, the warmth of her body slipped under the covers, and silence fell.

"Akame… I…"

"Shh," she murmured, fingers against his lips.

And then...

—

When it was over, Ryuunosuke lay awake, holding the sleeping Akame in his arms.

He couldn't sleep.

His mind was reeling.

If the cabin weren't soundproofed, the crew would've had a lot of questions come morning.

He let out a long sigh.

Just as he began to drift into thought—

Click.

The door opened again.

This time, it was Kuina.

She froze the moment she stepped in and saw Akame resting in Ryuunosuke's arms.

Both she and Ryuunosuke blushed instantly.

"I… I came at the wrong time," she whispered, hurt flickering in her voice.

She turned to leave.

But Ryuunosuke sat up, eyes serious.

"No. You came at the right time."

"Come here."

Kuina hesitated.

Then their eyes met—and she stepped forward.

Drawn in like a moth to flame.
