Chapter 5: Convergence of Power—Haki, Rokushiki, and Life Return

"Do you like this cabin? Or would you prefer two separate rooms?" Boa Hancock asked with a soft smile as she guided Hikari and Gin into a spacious, elegant chamber aboard her ship.

"This is perfect," Hikari replied, nodding with satisfaction. "We're fine sharing. By the way, how long until we reach the Sabaody Archipelago?"

Hancock paused in thought. "Hmm… a day or two, at most."

Hikari glanced around the polished wooden room, noting the craftsmanship. "No other questions. You should see to your crew. They'll need your help after that battle. We'll wait here."

Hancock gave a graceful nod. "Of course. I'll check on the others and return later with food." With that, she turned and left swiftly, closing the door behind her.

As the door clicked shut, Hikari turned to her son, her tone playful but sharp."Alright, Gin. You clearly know something about little Hancock and this crew. Spill it. Tell your mother everything."

Gin didn't hesitate. He shared all the information he knew about Amazon Lily, its Empress, and their combat capabilities.

Hikari raised an eyebrow, impressed. "So the women of Amazon Lily are all Haki users? Most wield Armament Haki, and some even Observation? They possess a natural affinity for both forms… Incredible!"

"It reminds me of Nadeshiko Village from our world," Gin mused. "All women there, too."

At the mention of Nadeshiko, Jiraiya's face flashed in Gin's mind. He remembered how Jiraiya had once infiltrated that village... and how it tied into Naruto's future.

"Maybe we should ask them to share their Haki training methods with us?" Hikari suggested.

Gin shook his head firmly. "Better not. Haki is the pride of the Kuja warriors. Asking outright might offend them or be seen as trying to steal their heritage. It's not worth the risk."

"Instead," Gin continued, his eyes gleaming, "we'll soon meet Hancock's predecessor—Shakuyaku, the former Empress of Amazon Lily. She's a master of both Haki types and has deep intelligence networks. Her husband, Silvers Rayleigh—the former right hand of the Pirate King—is a true Grandmaster of Conqueror's Haki. In our world, he'd be comparable to a Kage. Maybe not on Hashirama or Madara's level, but close."

Gin's voice grew more excited."We can learn Rokushiki, Life Return (Seimei Kikan), and maybe even get insight into Conqueror's Haki from them. That would be more respectful—and far more valuable."

"Someone near Madara's level?" Hikari's eyes widened. "Then his experience is worth gold. Do you think they'll agree to teach us?"

"I'm sure they will," Gin nodded. "Shakky and Rayleigh are grateful by nature. And if needed… I have information they wouldn't refuse. I'll get the secrets of Conqueror's Haki, Rokushiki, and Life Return!"

"If you're confident," Hikari said, then paused thoughtfully. "But tell me—what exactly are Rokushiki and Seimei Kikan? Are they really that important?"

Gin's eyes gleamed. "Absolutely. Rokushiki is a superhuman martial arts system used by the World Government's agents—designed to build immense physical power and control. It serves as a foundation for Haki training, especially Armament and Observation."

"But the real treasure," he added, "is Seimei Kikan—Life Return. It allows full control over every cell in your body. It enhances healing, digestion, physical regeneration, and even converts food into raw life energy. It's like chakra recovery on steroids."

"Control over every cell...?" Hikari murmured. "Then it could greatly speed up chakra recovery and amplify healing? That's a game-changer."

"Exactly," Gin affirmed. "But it's incredibly hard to master. Even in the world of One Piece, very few ever do. In CP9, where everyone learns Rokushiki, only Rob Lucci is known to have mastered Life Return."

"Difficult doesn't mean impossible!" Hikari smirked. "If I have the method, I will master it. After all… who isn't a genius?"

Gin chuckled. "That's the spirit!"

"But have you noticed, Mom?" he added. "People in this world… they're insanely strong. Much stronger than the average ninja back home."

"I've seen it already," Hikari agreed. "It must be the environment here. Everything seems… bigger."

"You're right. This world is home to creatures like Sea Kings—some are thousands of meters long. Even animals on land grow to dozens of meters. The people who survive in such a world evolve to match it."

"That gives me an idea," Gin said with a gleam in his eye. "We should start hunting Sea Kings and other giant beasts for food and training. Combine that with chakra meditation and Haki practice—it'll not only boost our physical stats, but restore life energy faster too."

Hikari's smile turned fierce. "That's a solid plan, son. Let's see how far we can push these new limits."
