One Piece: Unreal Adventure

After the phone call, Luffy finally knew what he would need to do… Why hadn't he thought of it before… every one was saying he was strong… so the strength wasn't the issue.

What he needed to change was his approach. He looked at the nameless blade… walking towards it. Sparky already got down from his shoulder and stayed back.

When giving tips on how to better use Observation Haki, Ace revealed something odd… which was communication with his weapon with the color of Observation. It seemed while training with Rayleigh, Ace had picked up the sword.

It came naturally to him. Shanks teased that Ace was still not anywhere near a swordsman according to his standards, but for a brat who took the blade for only a year, it was impressive.

It seemed that Ace didn't just come to thank Shanks, he already challenged the Red Yonko and lost in his dual.

So Luffy seeing the opportunity asked his brother on his secret. Ace wasn't even hesitant and directly said that he was able to get used to the sword because of his use of Observation Haki. Being a Logia user Ace had to always work on his Observation Haki. And for a new swordsman, it should have been a drawback.

But Ace was able to make it his strength. He was able to communicate with his blade, it also helped that the blade he was using wasn't any ordinary blade.

So Luffy took a page out Ace's book.

He grabbed the cold steel of the blade, not even putting effort to lift it. He didn't know if it would work… but he had a gut feeling that this was the way to make the nameless blade his.

So he poured his Observation Haki in it, or at least tried to feel the blade was trying to tell him.

The boy opened his eyes with new conviction. "I am sorry for being weak all this time… but I promise you… now that I'm strong, you won't have to meet any humiliating defeat again. And that's a promising partner…"

With that Luffy grabbed the naginata with both his hands, and pulled it. The blade almost accepted him, but this was the blade's last test for Luffy.

"Haaa!" Luffy poured his will into the blade as he tried to show it his ambitions, goal his drive for strength. He didn't hold anything back, if this blade was going to be part of his journey then he would treat it like any of his crewmates.

"I will become the strongest!" Luffy yelled, as the ground beneath his cracked. His muscles were already bulking and red, and even his hair stood up, Luffy didn't know it, but he unconsciously released a wave of Conqueror's haki.

Sparky who was a bit far from Luffy felt the wild use of Conqueror's Haki, but it didn't make him kneel or put any pressure on him. No… this haki was derived from his ambition, and this was a power that wouldn't harm his friend, so the six-armed monkey only felt the raw strength and will of his friend.

But the others animals surrounding the island weren't that lucky as most of them fell with foam in their mouth. Even the trees that were near him coward at the presence of a king as they leaned away from Luffy.

"I-I have done it…"

That brought the monkey's attention back to Luffy, who was holding the nameless naginata on his hand. The naginata that was a bit big for him had shrunken to fit his size while a chain came out of weapon and wrapped around Luffy's right hand.

Luffy was lightheaded, the sudden use of Conqueror's was too much for him. But he didn't kneel, as he was able to support himself with it… no it seemed that blade didn't let Luffy kneel.

Luffy had a shit-eating grin on his face as he was finally able to feel the blade… it was asking him to be strong. Strong enough to fulfill his ambition…

And Luffy nodded. "So are you going to tell me your name…"

The blade hummed in response.

"Fine… be a tsundere," Luffy mused, it seemed that the blade didn't deem him worthy enough to know its name it. "But anyway, thanks for giving me a chance… you won't regret it."

With that Luffy planted the blade on his back, the chains wrapped around his shoulder and waist crossways, making a place for itself on his back. "Huh, neat."

Only then did Luffy look around, and see the utter destruction of the environment around him.

"Hmm… that's unexepceted…" Luffy could see multiple birds and animals already knocked unconscious with foam in their mouth. He could kind of guess what happened. "But oh well… Sparky, let's do some training with our new friend."

The six-armed monkey was still at awe, but Luffy's voice broke him out. He saw the straw hat boy grinning ear to ear as he already took out Naginata from his back and was doing some light work with it.
