One Piece: Marine Luffy, Garp regrets it

"Are you kidding me? Could her strength actually exceed 4,000 Fighting power?" one Marine whispered incredulously.

"Otherwise, how could Bill be so thoroughly defeated with his considerable strength?" another responded.

"That's impossible. Even Lady Ain only possesses 3,500 Fighting power. Are we supposed to believe she's stronger than Lady Ain?"

"Well... it's not entirely implausible. Aren't there several individuals in Wano Country whose strength surpasses the Lady's? One more extraordinarily powerful person isn't completely unacceptable..."

As the discussions intensified around them, Reiju and Sanji stood in silence, exchanging meaningful glances.

At that moment, Bill—whom everyone had presumed "dead"—slowly opened his eyes. He coughed several times, then extended a trembling hand skyward.

"F-Fighting... power... 3,120..." he managed weakly. [Fighting Power=Doriki]

After delivering this vital information, Bill's head lolled to one side as he lost consciousness completely. Or rather, as he later justified to himself: "Just taking a strategic nap first, then I'll enjoy a feast when I wake up. Truly, I'm a genius."

Hearing this impressive number, everyone present drew in sharp breaths of astonishment. All eyes turned toward the pink-haired young woman standing calmly in the training field—her expression gentle, almost demure, belying the tremendous power she had just demonstrated.

"As expected of Germa... such incredible strength!" someone murmured, voicing the collective amazement of the gathered Marines.

While the onlookers marveled at Reiju's capabilities, her younger brother Sanji—who had appointed himself as her "guide" in her nascent Marine career—stood completely dumbfounded.

His motivation for rousing Reiju so early that morning, under the pretense of training, had been twofold. Beyond fulfilling Luffy's directives, he had secretly harbored the desire to demonstrate his own enhanced abilities to his sister after their years apart. He wanted to prove to her that he was no longer the vulnerable child who had once needed her protection.

However, reflecting on the numbers Bill had announced before losing consciousness, Sanji found himself utterly speechless, his expression a complicated mixture of astonishment, admiration, and perhaps a hint of wounded pride.

Reiju, naturally observant, missed none of this. The corners of her mouth curled upward slightly as she tilted her chin toward Sanji provocatively.

"Well? What do you think, Captain Sanji? Do I still require your basic training regimen?" she teased, her voice sweet but with an unmistakable undertone of triumph.

Sanji remained momentarily speechless, struggling to formulate a response.

"Hmph," he finally managed, affecting an air of nonchalance. "This level of strength is merely adequate—passable, but barely. Don't grow complacent. You might possess raw power, but you lack the refined techniques to complement it. Even with the disparity in our Dao levels, you're not necessarily capable of defeating me in actual combat."

To demonstrate his point, Sanji leaped lightly into the air, channeling his energy through his right leg to execute a powerful Storm Kick directed at a steel training dummy positioned nearby. The crescent-shaped vacuum blade that formed from his kick sliced cleanly through the metal construct, bisecting it with apparent ease.

Reiju's eyes brightened noticeably upon witnessing this display, and she offered a respectful round of applause in acknowledgment.

After landing gracefully, buoyed by the positive reception to his demonstration, Sanji regained some of his confidence. He crossed his arms and addressed Reiju with a slightly condescending tone:

"Next, I'll introduce you to advanced training protocols and instruct you in the Government's exclusive techniques—the Six Styles. I'll even guide your development of Haki, which will further enhance your natural physical capabilities."

Reiju listened attentively. As the princess of the technologically dominant Germa Kingdom, her knowledge base far exceeded that of ordinary North Blue inhabitants. At minimum, she was familiar with the terms "Rokushiki" and "Haki" from her extensive education.

However, under Judge's leadership, Germa had placed excessive faith in technological advancement. Consequently, Reiju's understanding of Haki remained theoretical and vague—she knew only that it represented an ability mastered by virtually all formidable combatants in the world.

This explained her careful attention to Sanji's words. For his part, Sanji was finally experiencing the satisfaction of demonstrating valuable expertise to his sister, making his earlier efforts feel worthwhile.

He provided Reiju with a concise introduction to the Six Styles and the fundamentals of Haki, eager to transition from sibling to instructor for his "new student."

Just as they prepared to begin practical training, Sanji's gaze traveled from Reiju's head to her feet, his brow furrowing as he examined her combat uniform with evident skepticism.

"While I'm not entirely certain what this outfit of yours represents, my instincts suggest you should remove it during training sessions," he advised firmly.

Reiju glanced down at her battle suit, considering his words.

"This is merely a standard combat uniform," she explained. "I happen to have another one with me. If you're interested, I could offer it to you."

The surrounding Marines froze, their expressions a mixture of disbelief and sudden intense interest.

"Battle suit?" Sanji repeated, dismissively. "I have no need for such devices. Keep it for yourself."

The Marines' collective disappointment was palpable, many suppressing audible gasps.

"Are you certain?" Reiju inquired, sounding genuinely surprised. "That's unfortunate. The spare unit is specifically designed for male users. If you truly don't want it, I suppose I'll simply discard it."
