Young Master, You Are Underestimating Me!

One Month Later

At Naval Headquarters, the Marine fleet stood ready to set sail.

Nearly every officer of Vice Admiral rank and above led their respective fleets, their mission clear: to cleanse the seas of piracy. From Admiral to recruit, every Marine carried a Hearthstone, the groundbreaking life-saving device now central to Marine strategy.

The Hearthstone device, stationed securely in the underground base's central square, had been tested rigorously over the past month. Every Marine had trained repeatedly in its operation, mastering its simple but invaluable functionality. With such a failsafe at their disposal, confidence surged among the ranks.

The new Marine Marshal, Finn, issued strict orders: in encounters with overwhelming foes, soldiers were to prioritize survival, using the Hearthstone to retreat instantly to headquarters. This directive ensured the preservation of Marine forces for the battles to come.

During the same month, Finn also directed Violet and Pudding to investigate the entire Marine organization thoroughly. Their efforts rooted out spies and traitors, leaving the Marines purified and prepared for the challenges ahead.

As the mighty fleet departed for the four seas, the sight was awe-inspiring, a display of power that sent shockwaves across the world.

Mariejois

In the sacred halls of Mariejois, before a grand throne surrounded by twenty symbolic weapons, the Five Elders knelt.

The throne, traditionally vacant as a reminder of shared governance, was now occupied.

Atop it sat Im, a figure shrouded in mystery and dressed in attire that seemed almost otherworldly. The towering hat and intricate robes only added to the aura of strangeness. Im's eyes, cold and disdainful, gazed down at the Five Elders as though they were mere insects.

One of the Elders, the bald man wielding a sword, spoke first. "Lord Im, we have urgent news. The Marines have launched an unprecedented operation. Their fleet, led by nearly all high-ranking officers, has departed Naval Headquarters."

Im's gaze remained calm, unreadable. "Are they moving against us?"

"No, my lord," the Elder replied. "The fleet appears to be dispersing, some heading to the Calm Belt, others to the far seas. It seems their target is... pirates."

A faint smirk tugged at Im's lips. "Pirates? How amusing. The new Marine Marshal certainly doesn't play by the rules."

The Elders exchanged uneasy glances.

"Lord Im, should we take this opportunity to strike Naval Headquarters?" the bald Elder suggested cautiously.

Im's smile widened, laced with mockery. "Have you already forgotten the lesson from our last attempt?"

The Five Elders stiffened.

"Marine's actions are peculiar," Im continued, their tone deliberate. "Observe for now. Gather intelligence. Only then will we act."

"Understood, Lord Im," the Elders replied in unison, bowing as they retreated.

On the Seas

Marine fleets moved swiftly, and Finn's flagship, a colossal super battleship, led the charge. Its destination: the Calm Belt and Nine Snake Island.

"Master! Pirates are looting nearby!" Nami rushed to Finn, her voice eager.

Finn leaned back, enjoying a massage. He opened one eye lazily. "Pirates? Convenient timing. Let's deal with them."

"Master, let me handle it this time!" Nami exclaimed, brimming with determination.

Finn chuckled. Over the past month, Nami had trained diligently, using special cards to cultivate top-level Observation Haki and Armament Haki. Though still inexperienced compared to seasoned warriors like Kuina and Tashigi, she was eager to prove herself.

"Alright," Finn agreed. "Take 100 female warriors and eliminate the pirates."

"Yes, Master!" Nami replied enthusiastically, already preparing to leave.

"Wait," Finn called out, stopping her mid-stride.

"What is it?" Nami frowned, turning back.

Finn glanced at Robin, who stood nearby. "Robin, go with her."

Robin smiled knowingly. "Understood." She approached Nami, ready to ensure her safety.

"Master, you're underestimating me!" Nami pouted, her hands on her hips.

"Prove me wrong, then," Finn teased. "Just don't get yourself beaten up."

With a huff, Nami stomped over and bit Finn's arm playfully before storming off.

Robin shrugged, her tone light. "Don't worry, Master. I'll make sure everything goes smoothly."

The two women left the ship, heading toward their first challenge, ready to make their mark on the battlefield.
