One Piece - Heaven Defying Comprehension!

Time flew by, and a month passed in the blink of an eye.

Ace was once again sent back to the Dadan family by Garp.

"Ace!" 

When Dadan opened the door and saw Ace, she was momentarily surprised, but quickly cleared her throat.

"Hmph! You brat, back again? You're such a bother!" she grumbled, trying to hide her joy.

A loud cough from Garp made Dadan snap to attention.

"Ah, Garp-san! You're here too? Would you like something to eat?" Dadan asked, her tone suddenly flattering.

"No, I have other matters to attend to. I'll leave Ace with you for now," Garp replied.

"No problem at all, Garp-san! Ah—" Dadan's sentence trailed off as she suddenly noticed something unusual. 

"Garp-san, what happened to your face?"

She stared at the burn mark on Garp's right cheek in confusion.

"Huh?"

Garp's expression darkened.

"Oh! My mistake! Of course, Garp-san couldn't possibly be injured! Haha..." Dadan laughed awkwardly, trying to brush off the topic.

"Ace, I'll teach you again next time I'm on leave. Remember, you must become an excellent Marine," Garp said sternly before disappearing in a flash.

As soon as Garp was gone, Ace smirked triumphantly. 

"Dadan, let's throw a party!"

Aboard Garp's Warship…

By this time, Garp had returned to his warship, heading back towards Navy Headquarters.

He stood silently on the deck, his hand gently touching the burn mark on his cheek.

Is this the power of the Mera-Mera Fruit? he thought to himself.

His mind flashed back to the final day of special training with Ace—the flaming blade that had soared toward the sky. That attack had far exceeded Ace's current abilities.

Even though Garp had been using his Observation Haki to help Ace control the power, the intensity of that blow still left him with this burn mark.

The destructive force of Ace's Mera-Mera Fruit surpasses even Sakazuki's Lava Devil Fruit at the same level… it's unbelievable, Garp reflected. The Lava-Lava Fruit was listed in the Devil Fruit Encyclopedia as the Logia Devil Fruit with the highest offensive power. Its flames could even burn other flames. In a sense, it was the superior version of the Mera-Mera Fruit.

Yet here Ace's Mera-Mera Fruit had unleashed a destructive force greater than Sakazuki's Lava-Lava Fruit.

Garp had a strong gut feeling that if Ace ever reached the same level of mastery as Sakazuki, the Lava-Lava Fruit would crumble before Ace's power!

Such a thing had never been seen before on this ocean!

"With power like that… Ace, you'll be just fine, won't you?" Garp murmured, smiling as he gazed out over the vast sea.

Three years later…

Ace was now ten years old.

During these three years, Ace met Sabo at the Grey Terminal, and together they began "collecting" money to fund their adventures. Ace's growth had slowed compared to the intense training with Garp, but his strength continued to improve steadily.

Thanks to his remarkable ability to absorb and master techniques like Turtle Breath, Ace's progress was smooth and unhindered. His natural talent and understanding of combat allowed him to roughly gauge his own strength. Physically, Ace estimated that his power was equivalent to a Navy Headquarters Colonel.

Of course, as a Logia Devil Fruit user, Ace was virtually untouchable to anyone who lacked Haki. In addition, he possessed the overwhelming force of Conqueror's Haki-Tangle, as well as powerful moves like Ring of Fire—Red Hole and Flame Sword Burial.

If he caught his enemies off guard and fought at full strength, even a Vice Admiral would struggle to escape unscathed against Ace.

In short, Ace's won't have a problem in the Grand Line.

But today, Garp arrived at Dadan's house with a new guest.

"Dadan, this is my grandson. Take care of him, too. Hahaha!" Garp said with a laugh, holding a seven-year-old boy by the hand.

"You've got to be kidding me! This isn't a nursery, you know! I'm not running a daycare!" Dadan protested, her anger flaring up. Is he trying to bully me because I'm too soft-hearted?! she fumed silently.

"Huh? Do you want to spend the rest of your life in prison?" Garp asked, his eyes narrowing as he released an intimidating aura.

"Yes! Yes! I understand! I'll take care of him!" Dadan immediately gave in, realizing there was no point in resisting.

"Ace, make sure you get along with him," Garp said as he turned around, looking at Ace, who was perched in a tree.

"Luffy?" Ace narrowed his eyes at the boy Garp was holding, noticing the sandals in his hand.

This seven-year-old was none other than the future King of the Pirates, Monkey D. Luffy—the boy who would go on to eat the Human-Human Fruit, Model: Nika from the Mythical Zoan class.
