One Piece: Rising to Power as a Warlord of the Sea

After hearing Natsu's suggestion, Katakuri stopped his impending attack, his mochi-based ability dissipating as he looked at Natsu with a serious gaze, as if trying to see through him.

"Non-aggression?! Peaceful coexistence!"

Katakuri began to think, especially after noticing the thunderous energy and the ongoing battles with his siblings in the distance. He realized that Natsu's suggestion wasn't bad.

Currently, the Big Mom Pirates simply didn't have the ability to fully wipe out the Smile Pirates. This operation had been too hasty by Perospero.

Without a strong enough force, it would be impossible to defeat the Smile Pirates.

"I agree!"

After pondering for a while, Katakuri finally spoke with a cold gaze at Natsu. Continuing the battle would only result in mutual exhaustion, and he didn't want to see his beloved younger siblings get hurt.

"Smart choice! Hahaha!" Upon hearing Katakuri's words, Natsu laughed happily. After all, Natsu didn't want to engage in direct combat with the Four Emperors' pirate crew just yet, as it would be too costly.

Once their opinions aligned, they both disappeared in a flash and quickly headed towards the battlefield where Enel and the others were.

"60 million volts—Thunder Dragon!"

"Stop, Enel!" Natsu suddenly appeared behind Enel, and his calm voice reached Enel's ear.

"Huh?! What's up, Natsu? I'm in the middle of a good fight! I finally found a group of decent opponents!" Enel shrugged, frowning slightly, looking puzzled.

His intense battle had strengthened his Conqueror's Haki, and Enel really enjoyed the feeling.

"We've reached an agreement!" Natsu responded with a smile.

"I haven't had enough fun yet!" Enel groaned in frustration.

"Don't worry, there will be more chances!" Natsu patted Enel's shoulder helplessly. He couldn't understand how Enel had turned into such a battle maniac.

"Perospero, stop! There's no need to continue fighting!" Katakuri also arrived on the Big Mom Pirates' side and explained the agreement with Natsu.

"What?! You agreed, but what will Mama say...?" Perospero's face darkened. After all, he had promised Big Mom to destroy the Smile Pirates, and now returning in this state would surely not sit well with Mama.

"I'll explain it to her!" Katakuri rubbed his forehead and said. It was better to personally explain things.

"Well then, everyone, to show our sincerity of non-aggression, here's a gift!" Natsu turned to Katakuri and his crew, his lips curving into a strange smile.

"A gift?!" Katakuri's expression changed. He didn't think natsu would have anything good to offer.

"Of course, Little Ryuji, come out!"

Natsu shouted loudly towards the sea. Suddenly, a massive wave surged upward from the calm sea, and a giant nine-headed  Ryuji appeared before everyone.

Feeling the terrifying pressure from the Ryuji, Katakuri took a step forward, shielding the others, his arms turning mochi-like as he prepared for battle.

"Relax, let me introduce you. This is the guardian beast of our Smile Pirates! Ryuji!"

Seeing the tense atmosphere once again, Natsu smiled faintly. He jumped into the air and appeared in front of Ryuji, gently stroking one of its heads. Ryuji enjoyed the touch.

"Let's begin, little one!"

"Roar!" A fierce but joyful roar echoed across the sea, causing massive waves to surge. The calm sea was soon disrupted by the soundwave, crashing onto the shores.

Purple liquid began oozing from the massive body of the Little Ryuji, dripping onto the sea, and in an instant, a thick purple mist began to rise from the surface, rapidly expanding. Soon, with Ryuji's powers, the toxic mist began to spread across the islands, creating a unique dividing line.

The mist grew, with a width of ten kilometers and extending nearly a hundred kilometers, continuing to spread outward.

Seeing Natsu's actions, Katakuri furrowed his brows, veins bulging. Was this how Natsu's idea of non-aggression worked?

Looking at the toxic mist dividing the sea, Katakuri tried launching a barrage of rice cakes, but upon contact with the mist, a sizzling sound erupted as the rice cakes were quickly corroded, their surfaces covered in countless small dents.

Such a terrifying ability made the Big Mom Pirates even more wary of the Smile Pirates. They now saw Natsu's crew as formidable, especially considering the new pet that could unleash such fearsome abilities. They began to wonder if Natsu was some kind of beast tamer.

"Hmph, let's go!" Perospero grumbled, his face dark as he turned to leave. However, the movement made his injured mouth hurt, causing him to wince in pain and hastily leave, not wanting to stay any longer.

"Good job, little one. I'll reward you with grilled meat when we get back!" Natsu turned to Ryuji, offering a praise-filled gaze.

"Roar~"

Hearing Natsu's praise, Little Ryuji worked even harder, expanding the toxic mist in every direction, sweeping across the sea. With the venomous mist, everything in its path fled. Of course, Natsu had already planned the route, so the mist didn't pass directly through the island but instead spread over the ocean.

"The Smile Pirates, Monkey D. Natsu, a dangerous guy!" Katakuri, riding on a ship, stopped and looked at the still expanding toxic mist, muttering to himself. Big Mom had once told him that those with "D" in their names were dangerous and rebellious, just like her former captain, Rocks D. Xebec.

A man who sought to be the ruler of the world and control everything, who tried to obtain the treasures of God Valley and was destroyed by the combined forces of the Navy and Roger.

"The Great Pirate Era! What is Pirate King Roger's goal?" Katakuri gazed at the clear sky, slowly closing his eyes, lost in thought.

"Let's go, crew, time for the banquet!" In stark contrast to the heavy mood aboard the Big Mom Pirates' ship, Natsu's crew was in high spirits. With a wave of his hand, Ryuji parted the mist and created a path. The crew boarded the Smile ship and set off for the Sea of Chaos.

"Looks like I'll have to install a teleportation anchor here next time; otherwise, it takes too long!" Natsu thought to himself.

On Smile Island, when the Smile ship arrived, the newly joined pirates erupted in cheers. Natsu's return meant that the Smile Pirates had survived the confrontation with Big Mom without suffering any significant losses. This signified that their captain, even facing one of the Emperors of the Sea, was not afraid.

"Everyone, prepare the food, let's start the banquet!" Natsu jumped onto the island, shouting at the top of his lungs.

"Yay~"

"Yo-ho, banquet time!"

"Banquet! Banquet! Banquet!"
