LUFFY VS ZORO

It's been two months since both Nami and Luffy left Orange town after defeating Buggy Pirates, they had been sailing and looting some no name pirates on their way. They even met the man who was stuck into the treasure chest, but they left him there on his request. In these two months Nami slowly but surely started to open up to Luffy little by little and one day she finally told him her true reasons about stealing moneys.

Even though Luffy, who had read the manga and already knew the backstory of Nami, he still got angry at hearing it in real life. He hugged Nami and reassured her that he will completely annihilate Arlong Pirates for her and save everyone. Nami cried a lot that day while still being hugged by him. Even though she still has some doubt about Luffy's strength, but she really liked the feeling of companionship she got from Luffy, maybe she is selfish but she doesn't care.

At current time, they were sailing towards their next destination Syruup Village, the birthplace of the Legendary Warrior 'GOD USOPP' himself. While sailing there Luffy told Nami everything about his system and promised her to make her stronger, so that what she endured in past, she never have to suffer again in the future. Nami was little suspicious about all this system thing but when Luffy told her that she can see with her own eyes when his First-Mate exit the chamber. Because it's been two months, Zoro's training should be about to end any moment.

Few minutes later, a light shined on the boat they were on and when the light dimmed they saw another figure is now occupying the boat with them. The figure is about 6'4'' tall with short light green hair wearing three golden colored tear drop shaped earnings on his left ear, an ankle length black coat which is tied by red shash around his waist, inside the coat he is completely bare upper body showing his long diagonal scar across his chest, a green haramaki along with black trousers and black boots. (A.N: BASICALLY HIS ONIGASHIMA RAID OUTFIT) There is a black bandana tied on his left bicep and a vertical scar is going down his closed left eye. He is none other than Roronoa Zoro who had just finished his two years training inside the Hyperbolic Chamber.

Luffy and Zoro looked at each other in the eyes then they both smirked and clasped eachother's hands with an extremely tight grip. "Long time no see…Captain!!!" "Yeah, but it was only two months for me….You sure became a real beast now!!!" Zoro just kept smirking and started to put more strength in his grip, but then both of them released their hands, not wanting to break the small and fragile boat with their grip strength alone. Zoro then looked at Nami with raised eyebrows, "Who is she??" Luffy smirked, "She is our new Navigator!!!" Zoro glanced at her then nodded, "If it is you, then you must had a good reason to invite her!!!"

Nami when first saw Zoro just appeared out of nowhere was shocked then when she looked at him carefully she realized he is Pirate Hunter Roronoa Zoro, "W…wait a minute…. Your first-mate is Roronoa Zoro???" Luffy looked at her shocked face, "Oh…sorry about that Nami, I didn't told you his name." Nami looked at him with annoyed look then calmed herself down, " 'sigh' Forget it…but tell me how did he just appear here out of nowhere??" "Remember I told you about my system…" Nami was shocked, "So that is real…. I can also become strong!!!" Both Luffy and Zoro nodded at her.

"You know if you want I can give some demonstration!!!" Luffy said to which Nami nodded, then Luffy looked at Zoro's swords or just a sword Wado Ichimonji, "Well Zoro, what happened to your other two swords??" "Huh??? Oh they broke!!! But for the time being the system gave me two spare swords to train but because my training is over I had only Wado left with me now." Luffy nodded at that, "I think I have a solution for that!!!" Zoro looked at Luffy with anticipation, "Hey System do you have sword store for Zoro??" suddenly a blue screen appeared infront of all three of them, this screen shocked Nami.

"AFFIRMATIVE"

"OPENING SWORD STORE"

"ALERT"

"THE CHARACTER CAN BUY ONLY THREE SWORDS"

Luffy nodded at that, "What will happen if we buy the same sword which is already present in the real world??"

"IF YOU BUY THE SAME SWORD WHICH ALREADY EXIST, THE SYSTEM WILL CHANGE ITS DESIGN AND COLOR AND YOU CAN ALSO RENAME THE SWORD AS YOUR LIKINGS"

"ALERT"

"DURING CHANGES, THE AURA OF THE SWORD WILL ALSO CHANGE AND IT WILL THEN ATTACH TO THE CHARACTER'S AURA MAKING HIM THE ONLY MASTER OF THAT SWORD."

I looked at Zoro, who after reading this nodded his head. Then I bought both Enma and Sandai Kitetsu and gave them to Zoro. "Now, give them a new name!!!" Zoro looked at his new swords and with the help of his Observation Haki he can feel the dangerous auras oozing out of them. He then unsheathed Enma and flow his Armament Haki into it turning the blade black. Suddenly Enma started to forcefully suck in Zoro's Conquerors Haki to which Zoro replied with releasing his all of his Haki into Enma. Nami who was sitting with them when saw Zoro just holding his sword up got confused because she didn't know anything about Haki and it is also an invisible thing, so she can't see anything too but she started to feel a very heavy feeling upon her. She almost fainted when a sudden warm feeling washed over her, she looked at Luffy who is holding her hand while still looking at Zoro. Luffy had just now enveloped Nami with his own Conquerors Haki.

Zoro who was feeding Enma with his Haki suddenly said, "FUSHIGIRI" Luffy's eyes widen hearing that and when he looked at the system, it had renamed Enma as Fushigiri then he looked at Enma which is slowly changing, the cloth wrapped around sword's handle become black with red underneath it, the guard of the sword turned into metallic colored sunflower shape, the sheath of the sword turned into red-wooden color. But the noticeable change is the blade of the sword, it started to turn into blood red color completely and soon the transformation finished and as soon as it finished, Zoro swing the sword downwards towards the sea and suddenly a dark-red crescent slash flew through the air, parting away sea water for kilometers and the clouds above also cut in two. Then the sword stopped absorbing Haki and went back to normal. Zoro inspected the sword a little more then he sheathed it.

Luffy looked at Zoro with shock on his face, 'That's the Mortal's Blade from Sekiro: Shadows Die Twice.' He then saw Zoro unsheathe Sandai Kitetsu and did the same thing with it but this time instead of sucking Zoro's Haki, the Sandai Kitetsu started to release its own aura, an aura of death. But Zoro did not faltered, he kept his Haki steady this time, "MUGETSU" he said and the sword started to turn, the cloth on the handle turned completely black with the guard shape turned into that of the Kanji 'BAN' means full, the blade of the sword still retained its slivery hue but with added dark black patches covering the sharp side of the blade, the sheath turned into black in color with crescent moon design printed on it. Zoro seeing the change nodded his head with appreciation and then sheathed his sword. 

Luffy looked at the two new familiar swords on the Zoro's waist, he then shook his head in resignation, 'Well good for him!!!' he thought then he looked at Nami, "So what do you think??? Do you wanna try it now or latter??" Nami who was watching the swords transformation shook her head out of surprise and then looked at Luffy with hope and new excitement in her eyes, "Yes I wanna try it….but not right now." Luffy nodded at her then he told Zoro about Arlong, hearing the Nami's story Zoro nodded and accept to help her.

Luffy looked at Zoro and used his Observation Haki to sense his strength, since he knew that in original canon, Zoro after training with Mihawk for two years, he was able to reach an insane level in swordsmen skill and unlocked his Armament Haki and Observation Haki. But now, not only did he learn under Mihawk but also under Roger too and he can clearly sense as a day that Zoro has unlocked all three of his Haki and well adverse with his Advance Armament Haki and maybe in Conquerors coating too. He still did not know how strong is Zoro's Observation Haki is? And did Zoro also learned Roger's signature move, 'KAMUSARI' or 'DIVINE DEPARTURE'.

Zoro also glanced at his captain with the corner of his lone right eye. Before when he saw Luffy move to intercept with bullets at Shells town, he could not able to see him move, but now after training for two years in that Chamber, he understood my Luffy is so strong even at very young age. He also knows that what he saw Luffy do is the fraction of his true strength and that feeling he got when Luffy made the Marines faint, now he knows that it was Conquerors Haki which he himself also possess.

When Zoro was first training under Mihawk, he found out that how weak he actually is and how he was just a small frog croaking in a small well not knowing the true extent of the world. But now, he has absolute confidence in himself that he can take on anyone as long as he didn't become arrogant.

Both Luffy and Zoro looked at eachothers and smirked, "Wanna test out???" Luffy asked, "Sure thing Captain!!!" Zoro replied with feral grin. Luffy looked at Nami, "Nami, is there any uninhabited Island nearby??" Nami looked at both Captain and the First-Mate then she sighed and looked at any island nearby and found a small island with no population, "There is one, but we'll reach there tomorrow!!!" "Well, set the course towards that island then!!!"

MARINEFORD---

Fleet Admiral Sengoku was in good mood because today he got less paper and now he is relaxing a bit. Seeing Sengoku so relaxed made Garp, who is also sitting in the office eating rice crackers, found it little concerning. So he chooses to ask it, "So Senny…did you contacted with Mihawk???" Sengoku looked at his friend and sighed, "Yes I did and told him everything about the situation. He said that he would see if he had time then he could test them a little, but he also warned that if the boy died then it is not his fault!!!" saying this Sengoku closely observed Garp's expression.

As he thought, Garp's face contorted into gloomy expression and he looked complicated. He could feel the unease radiating from his friend's emotion. Garp mood is really sour at the moment, 'Luffy, I hope you can get live out of this situation.' He thought. If just Luffy could've listened to his wishes and became a Marine then this event would've never happened.

Sengoku seeing Garp is thinking too much, so changed the topic, "Not long ago there was new news that he had recruited a new crew member." Hearing this Garp was little bit relieved thinking atleast his grandson is not alone anymore and if this new member is strong enough, they could survive Mihawk's test.

Garp looked at his friend, "Who is it??" "A former Pirate Hunter from East-Blue, had a very good reputation to be best Swordsmen there. His name is Roronoa Zoro. Although he is good but it is still East-Blue we're talking about which the weakest of all the Blue." Garp hearing Sengoku talking trash about East-Blue his own home turf just gave him an unimpressed look, 'Yeah the same East-Blue which birthed the Pirate King and his Right-hand man the Dark King. Me and my idiotic Son….and now my Grandson…' he thought and continued eating his rice cracker.

Back with Luffy and his crew, after a day of sailing they were finally on an uninhabited island. Right now only Luffy and Zoro were on the island and Nami is on the boat few kilometers away from the island watching both Luffy and Zoro with binocular. She still didn't understand why both of them had ordered her to get far away from the island, the island is already pretty much big so she thinks that it's a bit unreasonable, it is not like their battle will destroy the island. But she really wanted to see how strong both of them are, that...is there really a chance to defeat Arlong and his crew. She hope they do.

Right now with the help of binocular she can see both Luffy and Zoro were facing off eachother. Zoro looked at Luffy with his lone right eye and slowly unsheathed his Fushigiri and coated it with his Armament Haki and Conquerors Haki. Luffy seeing this also coated his right hand with his Armament Haki and Conquerors Haki. Nami who is watching them got confused, why are they just standing there and not doing anything, because she had not awakened her Haki so she can't see the Haki coating on Zoro's sword or Luffy's hand.

Then suddenly both Luffy and Zoro moved or more like just disappear from spot and finally a second later when their attacks were about to make contact with eachother, it stopped just few inches away but the force behind their attacks cause ground to rip apart, the trees tore off and flew away, the sea water started to move more violently and the boat on which Nami is on almost flipped over. Nami seeing all this with wide eyes and an absolute shock on her face, "W…what is this?? What is this power…their attacks are not even touching eachother!!!"

Slowly and slowly, Luffy's fist and Zoro's sword started to came more closer and when they finally made contact a bright light shinned and everything thing went silent. For Nami, it was like as if someone had just pushed a mute button and then it happened, a thunderous roar as if the heavens itself got destroyed. Nami had fallen on her back on the boat, when she opened her eyes the first thing she saw was that the clouds above the island had been parted into two. She groggily stood up on the boat again and looked at the island, only to witness that the island is completely ruined, the trees, the ground, the sea water is entering into the island, everything got destroyed. On the now ruined island, both Luffy and Zoro looked at each other and then at the ruined state of the island, "Man I really hoped that this island could atleast tank five to six attack. But now, it is about to collapse." Luffy pouted. Zoro nodded at that, "Although I also wanted to continue our test, but state of the island is not good so we must leave now!!!" with that both of them left the now ruined and scared island.
