--- Chapter 377 ---

Swoosh!

Admiral Fujitora kicked the air with some ferocity, causing a small vacuum that propelled him forward. Fujitora's Observation Haki spread toward the Sabaody District 1, hoping the Celestial Dragon hadn't gotten killed yet. 

Although Admiral Fujitora hated the Celestial Dragon for their untamed greed and vanity, he also acknowledged the World Government needed these so-called nobles to maintain a lofty image. 

There are pirates, and there are World Government and Celestial Dragons.

With Marines in the middle, they could intercept them with force. However, they could trick the World Government and Celestial Dragons in one way or another. 

Of course, Fujitora would rather deal with pirates than Celestial Dragons because the latter is literally too bothersome. 

'I need good drinks after this.' Fujitora thought. 

Fujitora's sharp sense suddenly sensed danger. He felt coldness in his neck like a sharp guillotine was hanging above him.

"What?" He stopped mid-air and landed on the rooftop, looking at his trembling hand. He even instinctively pulled his sword out. 

"What actually happened in District 1 to make me feel like this?" 

"Even Yonko 'Four Emperors' won't give me such feelings." 

"My Kenbunshoku Haki and bodily instinct warned me not to enter that area. If I enter, I might die..." 

Fujitora's face turned solemn. Was it worth it to sacrifice his life for the Celestial Dragons?

Such a question flashed in Fujitora's mind.

However, he sighed in the end. He couldn't disobey the order from the Fleet Admiral.

He pulled out his Den Den Mushi and called for support. Even though he has entered District 1, it's better to be cautious rather than dying in the way.

After the Den Den Mushi got connected, Fujitora uttered with a solemn expression.

"This is Admiral Fujitora."

"The target's strength is too powerful!" 

"I'm calling for support. Repeat, I'm calling for support." 

"Call Admiral Onigumo and Admiral Ryokugyu to the Sabaody immediately!"

"Roger!" A voice responded. "Admiral Onigumo and Admiral Ryokugyu are already on the way."

Fujitora's eyebrows raised a little. "They are coming here already? Did Akainu predict this?" 

"No, he probably distrusts me." 

Fujitora couldn't help but shake his head, "That guy..." 

"Well, let's do what I can do." 

After putting Den Den Mushi aside, Fujitora seized his sword and moved forward again. He ignored the goosebumps on his body, reaching for the source of danger. 

...

Meanwhile, Luffy and Kuina arrived at District 1.

"Woah! What happened here? Where are the people?" Luffy was shocked, finding not a single person in District 1. It was desolate, devoid of lives.

Kuina frowned slightly, "It seems Robin is causing mischief here..."

"Mischief? Robin, that's a bit..." Luffy tilted his head. 

"Well, maybe you're right. But Robin won't harm the innocent. I believe her!" 

"Because she's my Nakama!"

Kuina rolled her eyes, "I knew that too, idiot. Robin is not that kind of person." 

"However, if I had to guess... She might attack Celestial Dragons." 

"Celestial Dragons?!" Luffy choked on his barbequed squid. 

"Hurry, we need to look for Robin!" 

Luffy grabbed Kuina's collar again and ran with a 'solemn' look.

Kuina glanced at Luffy's expression and couldn't help but feel surprised because this idiot actually knew how to get serious. This much is 'naturally' expected from a man who becomes Zoro's captain.

They arrived at the main street and were surprised to see everything covered with white papers. 

When they meant everything, they really meant it. 

The buildings, ground, trees, and even some people.

"What is this? Devil Fruit?" Luffy stomped the paper on the ground with a curious look.

"No, it's Martial Soul," Kuina replied calmly. "To be precise... Well, Robin's Martial Soul did it." 

"Martial Soul? What's that? Can I eat it?" Luffy responded naturally.

"..." Kuina.

Kuina facepalmed, "Gosh..." 

"What kind of Gods cursed you with this level of intelligence?" 

"You're really a God's perfect idiot, Luffy." 

"Hehe, I am!" Luffy proudly smacked his chest.

"THAT'S NOT A PRAISE!" Kuina smacked his head decisively, causing the future Pirate King to roll around on the ground in pain. Of course, she controlled her strength as she didn't want to kill Zoro's captain.

"Painful! So Painful!" Luffy screamed. "I am made of rubber... And I've trained Busoshoku Haki with Rayleigh. How can a smack feel so painful??" 

Luffy felt wronged. 

Did he train wrongly?

It is Rayleigh's fault!

Not far away from the Sabaody Archipelago, a tall, white-haired elder sneezed while putting down a box of beers.

"Achooo~!" 

"Why did I sneeze all of a sudden? There is no way I got the flu. It must be that brat, Luffy!" 

"I only left him for an hour, and he already missed me? Hahaha~!" 

Of course, Rayleigh didn't know Luffy was cursing him. If he knew, he would return to Sabaody and smack that brat like a volleyball for not respecting elders like him. 

"Hmm? That's a huge fleet. What are Marines doing?" Rayleigh frowned upon seeing two Grand Warships, followed by many others heading to the Sabaody. 

It's not 'bad' to have so many Marines in one place.

"This will only happen when 'dangerous pirates' gather or..." 

"Celestial Dragons got in accidents, threatened perhaps?" 

"I should probably go back and check on my idiot student." The Dark King sighed because although Luffy had gotten strong, he was still not at the level where he could contain multiple Admirals.

Unknown to the Dark King, he will change his fate by returning to the Sabaody. 

...

Back to Luffy and Kuina. 

They finally arrived at the cave where Robin, Nami, and Brook had peaceful tea time. 

"Wow! IS THAT YOU, ROBIN??!" Luffy was shocked to see Robin's appearance.

Robin is still Robin, but she's much more beautiful now. 

Even Boa Hancock felt short compared to the Goddess Robin.

Robin smiled, "Luffy, long time no see!" 

After two years of not seeing her captain, Robin couldn't help but feel emotional. She could tell Luffy had matured, though the process was painful. 

Losing a brother isn't a good thing. 

Before Robin could react, Luffy barged into the cave and hugged her. It was a reunion hug with no bad intention, so Robin didn't mind and patted her captain's back a few times.

"Oh, you actually come with Kuina-chan." Robin spotted Kuina not far away.

"Don't call me that!" Kuina hissed at her. 

Robin giggled, "Raikou is right. You're cute when you get annoyed."

"Have you found Zoro yet?" 

"No, that green-haired idiot probably lost his way somewhere in the Sabaody." Kuina shrugged casually.

"That's such a Zoro thing!" Robin and three others laughed. 

After that, Luffy walked to Nami and Brook and excitedly hugged them. 

Nami and Brook smiled, patting their captain. 

"So, we're just short of Zoro, Sanji, FRANKY, and Chopper." Luffy counted with his fingers. 

Robin nodded, "Don't worry. They should be here soon." 

"Before that, Luffy. Take this, a gift from me." 

Luffy blinked at the item in his hand. It's an armband.

The armband is white with a green game in the middle.

"Luffy, you wear an armband once, right?" Robin patiently explained. "It will be the replacement for it." 

"The name is Armband of Power. It's a training item that could impose gravity, physical, and spiritual restraint on the user, allowing them to train without equipment." 

"You can even use the extra gravity to make your attack heavier. I believe you can explore it yourself later." Although Luffy's IQ is questionable, he's actually a combat genius with sharp instincts. 

"The green gem on the armband is spatial storage, allowing you to store food and drink, with 10-meter cubic space." 

"Here, let me demonstrate." Robin grabbed a cup and threw it into Luffy's armband, making it disappear.

"Woah, magic!" Luffy exclaimed, clapping his hand. 

"This... I'm afraid Luffy can't use it." Nami was the first to drop the bomb.

"Yeah..." Brook also agreed.

Robin shook her head gently, "The operation is simple. Luffy, you can try infusing your Haki into the armband."

"Okay." Luffy infused his Busoushoku Haki, sensing a space that Robin talked about. He also sensed the cup and pulled it.

"He did it!" Nami, Brook, and Kuina were shocked. 

'You guys really don't have faith in his intelligence, huh?' Robin was amused.

"Oh, someone is coming here." 

"It's Marine. An Admiral?" Robin glanced outside.

"Admiral? Someone at Caliber is here already? So fast!" Nami and Brook were in disbelief.

Robin waved her hand, sending a clone made of papers. "Go." 

"I will let my clone deal with him." 

...

...

Fujitora landed on the paper-covered building and stared at the cocooned Celestial Dragons with a surprised expression. While he cannot see, he can sense them.

And they are dying!

Robin's clone appeared before Fujitora, smiling at him.

"Well, well, well..."

"I didn't expect Marines to be so quick. As expected of a Celestial Dragon's dog."

"Who are you? Why are you doing this?" Fujitora drew his sword.

Robin glanced at the bloodied Celestial Dragons and replied, "I'm the Devil Child, Nico Robin. You must know me."

"As for why I'm doing this? I'm just bored." 

Robin wasn't afraid of the World Government and Marines after experiencing many things with Huo Yuhao.

So, revealing her identity is just a side chore.

Fujitora clenched his grip on the hilt, "Young lady, you're playing with fire right now!" 

Robin chuckled, "Fire? They are just worms in my hand." 

Fujitora sighed, "I have no choice." 

"Gravito!" 

An immense gravitational pull appeared and covered Fujitora's sword, bursting toward Robin at breakneck speed.

Robin flicked her sleeve, "World in the sleeve." 

A white energy escaped her sleeve and met with the gravitation pull, causing a shockwave in the area.

BOOM!

A vacuum was 'instantly' created and sucked some buildings, shocking Fujitora.

Fujitora frowned, "So, the danger is coming from you..." 

"Hehe, you should call me Demonic Goddess instead of Devil Child from now on," Robin replied with a faint smile. "But that's only happened... If you can survive." 

BOOOOM!

A burst of pale violet Haoshoku Haki exploded from Robin, covering the entire Sabaody Archipelago. Thunderclouds appeared, and the sea stirred wild.

Fujitora's body trembled as he laughed bitterly, "Haha... It is more troublesome than I thought."
