Vongola Primo in One Piece

Giotto was even stronger than he was five years ago, especially when it came to his Devil Fruit abilities and the utilization of Flame of Night. However, at this moment, the Flame of Night was his trump card, something he wouldn't reveal to the world unless absolutely necessary. In fact, in the world, no one knew that he could use Flame of Night.

Even within Vongola Family, only the Guardians and Arcobaleno knew that Giotto could use Flame of Night.

After exchanging blows with Garp, Giotto remained expressionless. He soared into the sky like a fiery tornado, with scorching flames on his fists before driving Fire Fist towards Garp.

Garp grinned and threw a punch in response. His fighting style was straightforward. Regardless of the opponent's abilities, as long as they weren't stronger than his overwhelming strength, he could defeat them with a single punch. That was how he had defeated all his opponents until now.

"Bam!"

Following a thunderous sound, Giotto's Fire Fist was instantly dispersed by the overwhelming air pressure of Garp's punch. The shockwaves from their collision sent tremors through the air!

"Giotto, show me your true strength. That one earlier is ticklish!" Garp laughed heartily as he watched Giotto hovering in mid-air.

"Is that so? Then how about this one?" Giotto responded calmly. The flame on his whole body was concentrated into his hand. A colossal fireball was formed in his grasp, and it span rapidly. The intense heat created a scorching wind, making the desert area even hotter.

Ace, who was watching from a distance, might have some complicated feelings at this point. After all, this was supposed to be his Devil Fruit power, and the attack was an improved version of Flame Commandment.

"Flame Commandment: Flame Emperor!" Giotto's deep voice echoed as he raised the immense fireball above his head! This attack wasn't flashy, but the tremendous power it contained made it too powerful to withstand for most people. Even some of the famous pirates would likely be reduced to ashes by this attack.

However, Garp was different.

To be honest, if his opponent weren't for Garp, Giotto wouldn't have attacked so recklessly.

"Is that all you've got? What about your Dying Will Flames? If you think you can defeat me with just your Devil Fruit abilities, then you're over your head!" Garp taunted as he enveloped his fist in Color of Arms Haki.

Upon seeing this, Giotto released the immense fireball from above and sent it hurtling towards Garp. The high-temperature flames left a distorted sensation in the space they passed through, even though it didn't actually distort space. It was just a peculiar visual effect, given the extreme temperature.

Watching the rapidly expanding fireball, Garp burst into laughter. He tightly clenched his fist, and enveloped it with Color of Arms Haki. Garp then threw a punch, generating overwhelming air pressure that collided with Giotto's Flame Emperor.

"Boom!"

The rotating flame ball and Garp's Haki-imbued punch collided, generating a tremendous shockwave. The force even made Giotto's arm numb briefly. He swiftly stepped back, shaking off the pressure transmitted through the fireball. 

He immediately formed circles of flames beneath his feet once more. Then, he concentrated it into his hands. This time, the flame was shaped into a fiery bow and arrow, and the flaming arrow turned blue, indicating that it was at least five thousand degrees Celsius.

"Supreme Flame Commandment: Sun Chaser!" Giotto's deep voice echoed as he fired the blazing arrow towards Garp. The intense heat caused the distortion in the air even though it was just the effect of a really high temperature.

Although Giotto's attack was formidable, Garp was one of the strongest combatants in this world. His mastery over Color of Arms Haki was exceptional. Faced with this attack, Garp stomped, and his overwhelming Color of Arms Haki wrapped his iron-clad fist. 

"Galaxy Divide!"

His Color of Arms Haki-imbued punch struck o the flaming arrow head-on. The collision resulted in only a subtle sound, but the fire arrow was completely destroyed by Garp's overwhelming Color of Arms Haki and dissipated in the air in the blink of an eye.

"Like I said, your Devil Fruit power alone won't be enough to deal with me, kid!" Garp triumphantly declared.

"My Devil Fruit powe alone should be enough to give you a hard time!" Giotto retorted immediately.

However, he had to admit that his Devil Fruit power alone wouldn't be enough to defeat the Marine hero in front of him. Garp's Color of Arms Haki was on a whole another level. In the previous clash, Garp had applied three aspects of his Color of Arms Haki: Hardening, Emission, and Internal Destruction, completely overwhelming Giotto's Sun Chaser. Even Knuckle and Alaudi's Color of Arms Haki was nowhere near Garp's level.

But coming to think of it, who said that his was to defeat Garp?

Giotto didn't even know why he was fighting this old man here. It seemed like Garp was just bored and decided to pick a fight with him out of nowhere.

But now that the battle had started, there was no backing down. Besides, his Devil Fruit power was not that weak.
