One Piece: Trainers on the Straw Hat Pirates

But with so many things happening one after another, Ace has finally grown from a reckless kid into a mature and steady man.

At least, the worst possible outcome that Crimson had predicted did not occur.

"Dad, where are you now?" Ace asked into the Den Den Mushi. "By the way, I received intelligence saying... Kingdo was captured by the Marines!?"

"With the help of Luffy and his crew, we captured over a hundred Marine officers this time."

"These prisoners can be used to trade with the navy and rescue our people."

"Luffy... is that the younger brother you mentioned last time?" Whitebeard, who had been relaxed, suddenly focused his gaze upon hearing this.

"Your plans on the Sky Island this time were also aided by your younger brother, weren't they?"

"Ace, you really have a good younger brother."

"Please thank him for me~"

Clearly, his inner self was not as relaxed and natural as he appeared.

After a long pause, he let out a long, deep breath and said in a deep voice:

"Based on the directions indicated by the life card, the Moby Dick should be in the waters near you now."

"Please have your brother wait a moment, we'll be there soon."

The call was quickly disconnected.

Although a lot had happened during this time, Ace had a lot to say to Whitebeard, but in order to avoid the Navy overhearing their conversation, they had to do this.

After hanging up the phone, Ace immediately looked at Luffy and Akame standing to the side.

Before he could speak, Crimson suddenly reached out and interrupted him, then smiled earnestly:

"Looks like our journey is coming to an end, Ace."

"……yes."

Ace paused for a moment, then smiled at his silly younger brother with the same expression:

"I never imagined that I would be taken care of by you one day, Luffy."

"Hehe~ It's all thanks to my crewmates!" Luffy replied with a grin.

……

……

Two hours later.

A massive warship, comparable in size to the island whale Laboon, suddenly appeared on the calm sea.

Countless insects flew out from the dimensional hole above the warship, carrying one after another naval officers and soldiers, bound like dumplings, onto the deck of the Moby Dick.

Compared to the ship that the Four Emperors used, the Going Merry looked so small and exquisite at this time.

At this moment, on the deck of the Going Merry, the Straw Hat crew stood by the railing, watching Ace return to his companions.

Gazing at the towering ships before him and the inexplicably chilling aura emanating from them, Zoro rested one hand on his sword and chuckled softly:

"Is this the warship of Whitebeard, one of the Four Emperors?! It's really impressive!"

"It would be so satisfying to cut down warships like that!"

"Hey, hey, calm down, Zoro!" Upon hearing this, Usopp hurriedly waved his hands in a panic, only to be met with a glare from Zoro that seemed to say, "Do I look like an idiot?"

However, before Usopp could catch his breath, a powerful surge of Conqueror's Haki suddenly erupted from around them, pressing towards the Whitebeard Pirates on the other side.

Caught completely off guard, the Whitebeard Pirates were instantly hit by Luffy's full Haki, and some of the weaker members immediately fell to the ground one after another.

"Um!?"

At this moment, everyone, from the Straw Hat crew to the Whitebeard Pirates, focused their attention on Luffy.

"Luffy, what are you doing..." Usopp looked puzzled, but secretly reached into his pocket, preparing for a possible battle.

The next second, Luffy leaped onto the ship's railing, slammed his straw hat down, and pointed at Whitebeard on the Moby Dick, shouting:

"Hey! You big guy, you must be the one with the white beard, right?!"

"He actually possesses the same Conqueror's Haki as his father!"

"...Is that person...Ace's brother?"

The Whitebeard captains, who were welcoming Ace, were instantly shocked as they felt the overwhelming Conqueror's Haki that moved them all.

Whitebeard turned his gaze over, a slight smile playing on his lips, and slammed the naginata in his hand onto the ground.

"Straw Hat Kid, are you trying to provoke me?!"

boom!!!

In an instant, a vast aura of Conqueror's Haki suddenly rose from the Moby Dick, its surging energy soaring into the sky and shattering all the clouds.

Then it charged toward the direction where the Merry was.

In an instant, countless black bolts of lightning burst forth between the Merry and the Moby Dick, tearing through the air and the void.

The surging waves pushed the two ships backward.

The strongmen of the previous era displayed overwhelming power against the contestants of the new era.

Luffy's Haki only lasted a few seconds before being overwhelmed by Whitebeard's Conqueror's Haki, forcing him to retreat steadily.

But then a slight look of surprise appeared on the white-bearded man's face.

Because when his domineering aura swept over the Going Merry, not a single member of the Straw Hat crew was knocked unconscious.

Do not!

Not only was he not unconscious!

Those bright, sparkling eyes represent them...

It wasn't affected by the domineering aura at all!

Of course, this does not mean that Usopp, Nami, and others are completely unafraid of the Conqueror's Haki of the Yonko level.

The reason they looked so calm and their eyes so resolute was because, in the instant Whitebeard's domineering aura pressed down...

A strange purple-pink glint suddenly flashed in Robin's eyes, who was standing behind the group.

The next second, she spoke with a soft shout:

"Wow, that aura is incredible!!!"

boom!!!

The aura formed from superhuman power was instantly released from Robin's body, part of which became a mental shock that clashed with Whitebeard's Haki.

The other part is the formation of a light screen move in the Pokémon world, which greatly weakens the overwhelming power and makes it lose its original domineering and imposing nature.

Robin's arrival is just the beginning!

Aww!!!

A hazy, ethereal dragon's roar suddenly echoed on the deck of the Merry.

Zoro suddenly took a step forward, and a powerful aura suddenly erupted from his body.

Although Zoro's Conqueror's Haki was still quite immature compared to Luffy and Whitebeard, it successfully helped Luffy stabilize his stance and prevent his aura from being overwhelmed by Whitebeard's Haki.

"I really can't do anything with you guys."

At the same time, seeing this scene, Crimson couldn't help but shake his head slightly.

After muttering something to himself, he stepped forward and unleashed all the superpower within him, transforming it into a mental pressure that surged towards the white-bearded man.

With the addition of Red and others, Luffy's Haki was instantly infused with a brand new power.

For a moment, he even seemed to be subtly overshadowing Whitebeard's domineering aura.

However, Whitebeard quickly unleashed an even more powerful Conqueror's Haki, maintaining his dignity as the "strongest man in the world."

The two men's domineering presence created a situation of fierce competition.

The once clear sky was split in two by the imposing presence of the two, with rolling clouds forming.

This scene left many of Whitebeard's officers with expressions of disbelief and shock.

At that moment, Luffy, head bowed, said in a low voice, "Is this the power of a Yonko?! I'm still far from it!"

However, after he finished speaking, he raised his head again, clenched his fists, and looked firmly at the white-bearded man, shouting:

"The Four Emperors - Whitebeard!"

"Although I hate to admit it, Ace declined my invitation."

He likes you a lot!

"So...you'd better protect him for me!"

"He is an extremely important family member to me!!!"

"If Ace dies, I will never forgive you!!!"

Under Luffy's gaze, Whitebeard revealed a crescent-shaped smile, but his eyes were incredibly domineering.

He let out a cold laugh:

"Hmph!"

"Kid! I can do it even without you telling me!"

I hope you can keep your word!

Luffy responded with a serious expression.

But the next moment, his aura surged forth once more.

"besides!!!"

He suddenly took a deep breath, and his body involuntarily showed some of the martial god patterns that he only had in the fourth gear state.

Luffy roared as if he had used all his strength:

"I'll become the Pirate King!!!"

"—It must be me!!!"
