One Piece: Unreal Adventure

When Luffy woke up again, he was at Makino's place, he quickly got up and found Garp and Sparky having a meal. Of course, Luffy was sour about his loss and challenged the marine hero.

Who denied his request this time…

"Too much training won't do any good other than overworking yourself." Garp had said. "And if it's about pestering me to learn Armament Haki… then no. I won't teach you that unless you join the marines. Besides your body is quite adaptable… if you were able to learn the Rokushikis then you might be able to learn Armament as well. But to learn that you have to join the marines, Bahahaha."

The man said the last part mostly to himself, but Luffy heard it just fine. For him, it was eye-opening. It meant his physical powers were close if not ready to learn the color of Armament. He just needed to figure out how.

After that Garp stayed for a few days, not even joining the boy's sparing sessions once, so Luffy was left to do regular exercises to increase his strength. And he was right.

The plateau that he was facing was now gone. He could gain more strength now. And that felt awesome.

Technique wise he didn't improve much, other than learning more about Observation Haki. He had even started journaling about how it works and whatnot. Even though the logic of this world was messed up, it still acted on some basic principles, and learning them would help him master Haki.

"Sparky, so what should we do about this one?" Luffy asked his six-armed monkey as he looked at the odd-shaped fruit.

When Luffy was on the unknown island he was able to explore it. Being an island on the clam belt it had some of the most dangerous creatures to be found. They were a lot stronger than any of the wild beasts in Dawn island, but were weaker than what Luffy expected.

Luffy was actually expecting beasts to be as strong as those that canon Luffy fought while training with Rayleigh. But that wasn't the case. They were, of course, stronger than Luffy even if he used all of his gears with his rokushiki he found it hard to beat them.

But they weren't as dangerous as they hoped. It seemed that holding out against Garp made the old marine underestimate his fighting abilities.

Sure he did show off the rubber version of tekkie, but Luffy made sure to play it off as a rubber body ability.

Anyway, it took Luffy around twenty to twenty-five days to conquer the island. And after that, he was able to explore it. Luffy had a bold idea to look for any hidden treasures… and so he asked the island animals about it.

Of course, Luffy couldn't understand them, but Sparky could. With that they found some old shipwrecks that were washed ashore on the beach. And after searching through some skeletons he found some gold and an odd-shaped fruit.

It seemed that the ship was a merchant ship. But looking closely it was more of a black market merchant ship. Luffy had even found some mermaid skeletons with normal human ones to make notice of it. It seemed the ship was trying to smuggle the mermaids to some rich nobles that lived in the blues.

So was the reality of this world, and so Luffy didn't mind taking the fruit for himself.

But the problem was… Luffy didn't know which fruit it was. Sparky seemed eager to eat the fruit and gain cool powers like Luffy, but the boy held the monkey off.

"Just wait for a bit more little guy… let's find ourselves a devil fruit encyclopedia first… we don't want you to gain one of the stupid powers," Luffy said. 

Sparky would be a long-time friend and a member of his future crew of course he would want the best possible fruit for him.

The monkey reluctantly agreed, and closed the small treasure box that held the fruit.

Luffy had contacted some of the criminals that were in contact with the black market to get himself a devil fruit encyclopedia. But it seemed they didn't have access to that high level of stuff, so Luffy would have to wait and ask Shanks for it. Asking a Yonko for mundane things was quite shameless, but Luffy never cared that much for anything.

"Hey, buddy don't feel down… if the powers are good. I have no problem letting you eat it." Luffy said, patting the monkey, "But I don't want you to end up eating a stupid fruit that won't help you at all."

The monkey seemed to cheer up a bit. Luffy didn't know how old the monkey was, but by how he acted it seemed that he was still a kid. So, Luffy could understand the impatience.

For now, Luffy stashed the fruits and treasures away. With the added treasures that he liberated from Goa kingdom nobles and the occasional shiny objects that he found around the island, Luffy was making up a good amount of treasure to start his journey.

So after looking over his treasure vault, he went out for a walk.

"Buddy, let's see if I am strong enough to lift that."

The monkey looked at the straw hat boy curiously, as he sat on his shoulder. After a bit of walking, he was in front of the nameless weapon. His nameless naginata.

With his observation Haki, Luffy was able to see the strength of the magnificent blade. "Well, hello there… I hope you deem me worthy enough to lift you."

Luffy removed the dusted cloth as the full view of the weapon came into view. "Sparky you might want to step away a bit."

Luffy grabbed the weapon with two hands as he started to put strength into lifting it. "Let's put my back into it…" But it seemed the more strength he put on, the more heavier it got. "Fine, we do it the hard way." Luffy's body bulked up, his skin turning red as steam started coming off, even his hands and feet were getting enlarged as he put on full strength. "You are mine… got it. I will become your master."

Luffy roared as he finally was able to lift the blade off the ground for a just few inches. The ground around him was already forming spider cracks due to the struggle. But just as the weapon was lifted, it suddenly became even heavier and planted again into the ground.

"Uh…" Luffy took a few steps back as he failed to lift the naginata and he was panting profusely due to the struggle. "So I'm not ready huh… well, I will be… I will make you mine and that's the last thing I will do before I start my journey. And that's a promise."

The six-armed monkey looked back from the weapon to Luffy, he seemed shocked that there was something heavy that Luffy wasn't able to lift.

"Come on sparky, let's get back to training," Luffy said, grumbling his way out of the forest. "I should also ask Shanks for some sea stones the next time we talk."
