"No, everyone, please stop! don't harm each other!" Yelled Vivi as she watched the royal army and rebels suddenly starting to attack each other for no reason.

It started with only a few people, but then they slowly rose in number and they were still rising if anyone doesn't quickly intervene to stop them!

"M-My body... it's moving on its own!" Yelled a royal soldier before he shot a civilian that was getting evacuated and one of the rebels that saw him instantly retrieved his gun and aimed at him "You bastard, how could you shoot at civilians!"

"Kumo, stop! this situation doesn't appear normal" Said his friend, but just as Kumo hesitated, that royal guard moved like a marionette on strings and aimed his gun at his friend before he pressed the trigger with a fearful look on his face that didn't match his cruel actions!

"NOOO, YOU BASTARD, I WILL KILL YOU" Yelled this rebel Kumo before he aimed to shoot that royal guard but Koza suddenly rushed at him and stopped him in the nick of time while another one of his officers immobilized that royal guard...

"I understand your pain, but now isn't the time to be reckless, something doesn't feel right about what's happening here, we can't become divided at this point" Yelled Koza at the top of his lungs making Kumo and the many people that experienced the same situation as him to grit their teeth and the situation instantly turned chaotic until weird light started flashing above the two armies and broke the invisible strings manipulating them...

And it made one man that was watching everything from the sky in intrigue lose his wide grin...

...

"Damn that was close... That guy is really crazy, not caring at all about normal people..." Muttered Yuki who just cut the strings thanks to his Haki and newly found mastery of the way of the sword.

Then, he noticed that most of the fights started to conclude and only Luffy's fight remained… he could see that he was defeated and poisoned again but Robin was helping him

"Tch, can't he just win from the first try… This guy basically wins by exhausting his enemies mentally…"

Then, Yuki calmly started making his way to the palace while avoiding the crowds of civilians that were rushing out of the city and slowly emptying the streets which made him relieved and he could see that Pell and Chakra were trying to buy some time and stop Crocodile who wanted to kill everyone for ruining his plans…

However, Luffy soon came out of the crumbling palace and started beating him up with all of his strength…

"Smoker is making his way over too huh? it seems like the evacuation mission is almost complete…" Muttered Yuki as he stared at the unconscious Crocodile flying high into the air while Vivi and her father Cheered widely

Even the Strawhats made their way there wanting to help their captain, But that's when everything changed… Someone suddenly descended from the sky and kicked Luffy that was still in the air causing him to fall like a meteorite!

"Luffy!" Yelled Nami as she tried to rush to him the injured Zoro and Sanji stared at the new arrival…

He was a very tall man that was 3 meters (10 feet) Tall, he had short blond hair, a tanned body that was very muscular and lean, and he was wearing flamboyant clothes that were topped with a pink feathered coat. He was also wearing a pair of curved thin white sunglasses that had purple lenses. This was the warlord of the sea, Donquixote Doflamingo!

"HEHEHEHE Crocodile, what a disgrace, losing to such weaklings that can't even punch properly..." Spoke Doflamingo while holding the unconscious Crocodile by the head…

"Doflamingo… It seems like Yuki didn't lie to us" spoke Smoker as he faced Doflamingo and said "What are you doing in this place?"

"HEHEHEHE Alabasta, such a unique kingdom with a unique history how can I not come?" Spoke Doflamingo with a sinister smile on his face and Robin couldn't help but exclaim in her head 'Does he know about the history of this kingdom?'

However, her curiosity soon wavered as Doflamingo said "Now then, time to get rid of some bugs…"

"This bastard…" the injured Zoro glared at Doflamingo but the latter simply waved his hand at him causing him a sickening sense of danger that made him jump away and just as he did, the house behind him was split into pieces!

"T-This.." The Strawhats were shocked by what a casual swing from this newcomer's hand could do and Usopp directly yelled "GET LUFFY AND RUN!"

Smoker Ignored the Strawhats and rushed to stop Doflamingo who started to manipulate his soldiers into shooting each other, but he only ended up getting smacked into the ground and vomiting blood as Tashigi ran to his side

"CAPTAIN!"

"I'm fine…" Spoke Smoker through gritted teeth as he stared at Doflamingo still standing in the sky above them with his iconic grin, and he appeared to be about to attack the Strawhats that were attempting to run away but two people suddenly appeared on the scene

"Yuki!" Nami screamed in delight when she saw Yuki while he simply nodded at her and said "Tell Luffy you each owe me another 10 million berries after this… Yurei, take everyone away"

"HEHEHE, You are the guy that broke my parasite strings huh? I don't know who you are, but no one will be leaving this place ali-" Doflamingo didn't even get to finish his words before a giant flaming arrow that was almost 2 meters tall came flying from one of the buildings and passed right through his body leaving a gaping hole in it…

"OHH, who attacked just now? Is that guy even alive after this?" Yelled Usopp as he kept staring behind him while Yurei carried them away with his telekinesis…

"It's one of Yuki's weapons, although that guy doesn't seem to have taken any significant damage…" Responded Yurei worriedly

Meanwhile, Doflamingo still didn't take Yuki seriously and simply yelled "I said none of you will escape" and was about to capture them with his strings. Yet, Yuki suddenly disappeared and reappeared in front of him and sent him flying with a kick to the jaw that was coated with his full powered armament Haki that reached level 2 after his ten days of training with Sabo!

"Agh…" Doflamingo flew rapidly and smashed into many buildings as some blood leaked from the side of his mouth, but he then stood up and stared at Yuki seriously for the first time and asked "Who are you?"

"Heavenly demon Doflamingo… I'm just a simple pirate, don't worry about my identity" Replied Yuki casually prompting Doflamingo to laugh loudly and say "You? a simple pirate can be this strong in this part of the grand line… Don't make me laugh"

"Anyways, can you let those guys leave, I don't really want us to fight for no reason" Spoke Yuki with an awkward smile but Doflamingo simply wiped the blood on the side of his mouth and said "There are plenty of reasons for us to fight now..."

"You leave me no choice then…" then, the heavenly demon and Yuki rushed at each other and both threw out a punch clad in Haki…

The result of the clash was Yuki flying through the air and crushing multiple houses before stopping 'He's strong both in terms of Haki and physically… He's not someone like Crocodile that only focused on learning how to manipulate his devil fruit better…'

'Hmm, why did it feel like I punched something extremely hard…' Wondered Doflamingo while staring at his hand which felt a bit numb before he slashed at Yuki with a whip made of his strings that can even cut the hardest of steel!

'This is going to be a tough fight…' thought Yuki as he instantly dodged the whip and rushed at Doflamingo again…

…

"Oy Yurei, don't drag us away, we need to help Yuki!" Yelled Luffy who was very exhausted and Zoro shared the sentiment but Yurei simply stared at them eerily giving them chills before he said

"Yuki knows what he's doing… plus take a look, even this guy with his logia won't be of help and might lose his life, what do you think will happen to you lot?"

"Are you calling us weakling?" Spoke Zoro through his gritted teeth while the wound he received from Mihawk ached slightly, and seeing this, Yurei shook his head calmly and replied "No, you guys are strong, but I know better than any of you what kind of monster Yuki is, and if he wants you to get the hell out of here as fast as possible, that means this fight is going to be terrifying…"

"How strong can he be…" Spoke Nami but suddenly, a burning red string came flying by their side and they could faintly see a silhouette blocking it before going through countless buildings and leaving behind nothing but utter destruction while the sand on the ground turned into glass!

"This is…" Nami felt her heart shaking slightly and everyone else felt the same as they stared at the man that was heading their way at a rapid speed by jumping in the air while screaming "HAHAHA, foolish kid, taking my attack head on to protect them, and here I thought you will entertain me for a bit more…"

"That guy was hit by this attack?" Sanji's mouth widened to the point that he dropped his cigarette from his mouth, and the rest all felt a chill including Luffy and Zoro as they watched Doflamingo charging up another similar attack "OVERHEAT!"

Another flaming and long whip extended from the palm of Doflamingo's hand and he prepared to destroy them with it while they were still worried about Yuki's well being

"Yurei, do something!" Yelled Usopp at Yurei who had complete control over their bodies while Nami and Chopped hugged each other but Yurei simply smiled creepily and said "Don't worry, Yuki is even more resilient than a cockroach!"

"Eh?" Luffy was surprised but just as the red string neared them, ten Giant crossbow arrows that were covered in frost came flying from the distance and knocked the flaming whip to the side while Yuki whose upper half was now exposed after his clothes got destroyed suddenly appeared in front of Doflamingo with a sword in his hand and said

"I'm your opponent… Dark strike!" A cold light flashed through Yuki's eyes as his sword instantly disappeared and slashed at Doflamingo who was only able to dodge the first attack thanks to his observation Haki but the other two connected and left two giant slashes on his chest… although they weren't too deep as he used his Haki to protect himself...

"T-This…" Zoro's eyes widened in shock as he witnessed Yuki's swordsmanship and he couldn't help but wonder 'I didn't see him slashing at all…'

Meanwhile, Luffy's eyes shined like two sparkling stars as he yelled "OHH, Yuki that was so cool…"

The rest of the crew cheered as well while Smoker and Tashigi weren't able to hide their shock.

"You… it seems like I underestimated you" Doflamingo had a few veins popping on his forehead before he muttered "Athlete!" And sent Yuki smashing into the sandy ground with a devastating Haki-covered kick.

However, this time he knew that Yuki was probably still alive so he suddenly waved his hand causing everything around them, the buildings, the sand... everything turned into strings before he said "Flap thread!"

"So you are finally getting serious..." Muttered Yuki with a cold smirk on his face...
