It takes ideas for three characters to introduce.

_ A bodyguard for the Germa 66 group (I don't care whether it's a man or a woman)

_A child or a talking animal who will be Yamato's ally (he still has to be badass enough for Kaido to consider him as a member of his crew)

_And a person joining the CP0 (to make it a secondary antagonist)

'' Monkey D. Luffy ? ''

Being in his palace, Neptune had just repeated the name that Shyarly had just spoken. being bowed before the enormous king, the mermaid nodded.

"Far be it for me to discriminate against him or to scare you, your majesty ... but it looks like he will become someone to watch in the future. ''

'' Did you have visions? ''

''Yes. ''

'' What did they show you? ''

''It is difficult to explain ! All I can say is ... the world will be turned upside down. ''

'' The world ? ''

Scratching his beard, while being thoughtful, Neptune finally asserts.

"As king of the Island of the Fishmen, I don't intend to interfere with my kingdom in a human story! So while I understand the need to watch over this boy, I don't plan to do anything to stop him until he comes here. ''

"I understand, your majesty. Shyarly asserted. "I just wanted to warn you that ..."

Suddenly, feeling another flash in her head, the siren winced, before screaming in pain.

"Shyarly-san? " Neptune wondered.

Only able to moan in pain, Shyarly caught sight of a new vision.

"Emma, do you realize what you're going to do? " Sabo roared. "Think about it, if you allow Zephyr to carry out his plan, all of Wano Kuni will be destroyed. ''

''So what ? " Emma asked simply, putting on a stoic expression. "By killing Kaido, we will prevent the rest of the world from being destroyed! To accomplish this miracle, a sacrifice is necessary. ''

'' Grrrr! Do you realize what you're saying? Emma ... I can't believe a person like you could say such words! You've gone completely mad. ''

'' How dare you tell me that? " Emma roared. '' You were not there ! When Luffy, Ace and I were getting killed, you weren't there to protect us! My friends ... All my friends are dead. ''

Suddenly rushing towards Sabo, she tried to punch him but the man managed to grip her fist in his palm. Being then crying with rage, Emma questioned him.

"Where were you while I was getting killed? ''

Seeing a second vision, Shyarla thought her head was going to explode.

"Oz! Get out of my way. " Big Mom ordered him.

Standing in front of Yamato and the yonko, the huge giant roared.

"You are not my captain! Now, I am the shogun of Wano Kuni. ''

Clenching his fist, he covered it with Busoshoku Haki, before pointing it at Linlin. Immediately jumping to the side, Yamato moved away from the huge woman enough to avoid getting hit too. Not reacting in time, Big Mom was hit by the huge fist and found himself thrown against a wall, which was pulverized. Seeing her disappear under a pile of rubble, Oz threw his fists in the air before asserting.

'' I am the strongest! I am Oz, the demon. ''

'' OZ! OZ! OZ! OZ! " Juki, Goki and Jaki shouted, cheering on their new master.

Uninterested in the giants stomping, Yamato hurried away. However, she hardly took two steps when she felt a powerful aura. Screaming, Big Mom ejected the rocks which crushed her. Then, catching her breath, she showed an enraged face, as blood flowed down her forehead.

'' OZ! I intended to make you an inhabitant of Whole Cake Island, so that I would reunite all the peoples of this world. ''

Suddenly using her haki, she knocked out everyone around her and the giants, before asserting.

"I'll spray you. ''

Unable to take it anymore, Shyarly scratched her forehead as the third vision arrived.

"Did you see it, guys? " A pirate asked. "Captain Buggy declared war at Nazarick. ''

'' Yeah ! Even Ainz doesn't scare Captain Buggy. ''

"Huh? " The clown wondered, as several people cheered him. "What… What? ''

"We're with you, Captain Buggy. ''

''Yeah ! We're gonna help you to kill Ainz. ''

'' That ? A moment ! I ... I ... ''

'' What did you say ? ''

Freezing in terror, Buggy finally lifted his gaze, to see a flying humanoid creature staring at him in rage.

"What did you say about Ainz-sama? ''

"Huh ... I ..." stammered Buggy, feeling snot trickling from his nose.

Attempting to smile, the flying man could not calm his rage, while he finally affirmed.

"I promise you such an excruciating retribution that death will be a tickle, in comparison. ''

"Mom ..." Could only say Buggy.

Arriving to help Shyarly, the palace guards saw her roll on the ground, as she had one last sight.

Watching in dread the two huge monsters that had just appeared, as well as the mysterious warrior covered with his green aura, Sentomaru began to scream.

'' UNCLE! We must stop Mugiwara and his crew at all costs! Because if they manage to reach the new world and recruit other teammates, we'll be in big trouble! ''

Seeing the masked man pulled with his bazooka, Raynare moved in front of him, before creating a magic shield. Hitting protection, the bazooka shot created an explosion that spawned a cloud of smoke.

'' Grrr! Motherfucker ! " Zoro growled, pulling out one of his sabers.

However appearing through the smoke, the masked man gave him a powerful kick in the face, which made him back away.

'' That ... ? " Sanji wondered, as the smoke barely had time to settle.

Also struck in the face, he was taken by surprise by the enemy. Once he was on the ground, the masked man rushed straight to Nami and Vivi, who could only scream in fear, seeing him point his bazooka at them.

However, jumping to avoid a lance of light, he groaned as Raynare rushed towards him.

''You want to play ? We are going to play. ''

Jumping up the pole, the masked man was soon joined by the fallen angel, while Eevee was on her shoulder. Noticing her black wings, the masked man began to growl.

'' Black wings? I am going to slaughter you, you creature of Satan. ''

'' What did you call me? " Raynare roared.

Guided by anger, she began to attempt to stab him with two more spears of light. Using a shield to protect himself, the man managed to repel her attacks, while also looking for the best time to use his bazooka.

Seeing herself out of danger, Nami began to roar.

"Guys, a little motivation! What's the matter with you? ''

"That motherfucker ..." Sanji growled, trying to get up. '' I feel weak ... ''

" It's impossible to make a move without being out of breath. " Gin asserted.

'' Truly ? So why can Raynare fight without a problem? ''

"She's a fallen angel. " Lucy reminded her. " Before she was one, she had to be an angel who lived in heaven and used to fight under these conditions! The lack of oxygen is no problem for her ! And she's not the only one. ''

Looking at Menma, she declared.

" Spirits don't need to breathe to live. ''

Indeed, feeling as good as usual, Menma wondered why the others felt so weak.

'' Perfect ! In that case, take your gun and go help Raynare. " Zoro ordered her, trying to get up. '' Hold him back until I'm up the mast! I'll slice it. ''

Taking up her weapon, Menma prepared to use her wings to fly. However, barely her feet left the ground when she felt immense fear. Thinking back to what had happened before they got to Jaya, Menma felt like she was feeling the pain she had had when the bullet had passed through her abdomen.

Immediately she stopped using her wings, and the others could see her shake in fear. She was afraid of flying.

''No, I can't. ''

''Idiot ! " Zoro growled, before starting to climb up the mast.

At that moment, dodging one of Raynares' spears, her enemy gave her a powerful kick in the face, which made her bleed from the mouth. Seeing her fall back, Eevee jumped off her shoulder, before creating shooting stars.

Eevee use METEOR.

Seeing the projectiles, the masked man positioned his shield for protection, while the meteors only struck his shield without damaging it.

"A divine spirit? " He wondered, staring at Eevee.

Noticing that his attacks didn't have enough power to hit him, Eevee focused more power and created a purple sphere.

Eevee use SHADOW BALL.

However, like in her fight against Noscula, Eevee couldn't handle this attack properly and the purple sphere lacks power and precision. Having no trouble avoiding the attack, the man also punched Eevee and sent her flying until Raynare managed to grab hold of her.

'' Are you ok Eevee? ''

However, her pokemon didn't even have time to make a sound that their enemy fired again with his bazooka. Having no time to create another magical shield, Raynare hugged Eevee close, before turning around. The projectile hit the fallen angel's back, causing her to cry out in pain, as the explosion knocked her onto the floor of Vogue Merry.

" Raynare. " Her companions frightened. ''

"DIE, demonic creature. " Roared the masked man, targeting Raynare again.

However, hit by a punch, he nearly fell off the mast, while Luffy appeared next to him.

'' Motherfucker ! You'll regret doing this. ''

Simply growling, his opponent jumped high above the mast, before targeting the ship with his weapon, seeing it pulverize in one hit. However, it was at that moment that a figure appeared in the sky, while screaming.

'' It's enough. ''

Immediately raising his shield, the masked man managed in extremis to block the combat spear of an old man in armor, riding a strange giant pink bird.

Even though he had managed to block the attack, the masked man was pushed back and, falling back on the clouds, he used the power of his shoes to allow him to escape. Seeing this, the armored old man collapsed too, before landing gracefully on the Merry's floor.

Immediately, Johnny and Yosaku pointed their swords at him, while screaming in fear.

"HEY! WHO ARE YOU ? ''

Despite the guns pointed at him, the man asserted.

" I introduce myself! I am the knight of the heavens. ''

'' Knight? ''

Falling off the mast, Luffy asserted.

''He left. ''

"Raynare, are you okay? " Chopper asked her.

Managing to get up, Raynare had the skin on her back burned. However, having wanted to protect her wings, she had made them disappear before the explosion. Wincing in pain, she saw the knight watching her. Seeing the masked man's reaction, when he saw her wings, she thought it was a good thing that the old man didn't know that she was a fallen angel. Finally, this place could indeed resemble a paradise where fallen angels were hated.

Not seeming to realize that she was a fallen angel, the old man asserted.

"It's been a long time since I've met a Blue Sea Dwellers. ''

"Blue Sea… what? Nami wondered.

"This is the name we give to the inhabitants living on the blue sea, under the clouds." The knight told her.

"Sir… thank you very much for saving us. " Vivi thanked him, bowing politely to him.

'' You're welcome. " The man assured. '' In view of the urgency, I preferred to intervene! And since I did not have time to introduce myself and talk about my fees, before the fight, we can say that my intervention is free. ''

'' Fees? " Gin wondered.

Preferring to ignore the question, the knight let himself know on the Merry's railing, as his giant bird landed beside him.

"You nose the blue sea, don't you? I see you are surprised by the lack of oxygen! It's normal ! You are at an altitude of 7000 meters. ''

'' 7000 meters? " Bruno repeated. " And where is the Sky Island? ''

" Do you mean Skypiea? She is 3000 meters above us! So 10,000 meters above the blue sea. ''

Staring at the crew, he confessed.

"I'm surprised to see you here and I'm not asking how you got lost here. ''

"Hey, grandpa. " Sanji called out. "Thank you also for helping us but, would it be possible for you to tell us where to go to go higher in the sky? ''

'' A moment ! I know you have a lot to ask of me! However, before that, I would like us to talk a bit about business. ''

'' Business ? ''

"I am a mercenary knight and this white sea is teeming with danger! Therefore, in exchange for monetary compensation, I would be ready to help you! I don't want to scare you, but if the man who attacked you returns with his comrades, he's sure to succeed in destroying your ship. ''

'' Because he's not alone? " Lucy scared.

"My help will cost you 5 million extols, per whistle. ''

'' Extols? " Yosaku repeated, turning his head to the left.

'' Whistle ? " Usopp repeated, turning his head to the right.

'' QUA? " Carue said, standing between the two men.

Sighing wearily, the knight guessed.

"You've never heard of Skypiea's currency unit, right? ''

'' Indeed ! We weren't even sure the Heavenly Island existed. ''

'' What ? " The knight wondered, looking shocked. " Are you kidding? Wait a minute, you made it through Highwest, right? ''

'' Highwest? " Robin repeated.

'' WHAT ? " Usopp shouted. " Was there another way to reach the Sky Island? ''

'' Sure ! Given the number of celestial islands that exist, you can imagine that there is one that has found a way to create a path between the blue sea and the white sea. ''

"There ... are there several heavenly islands? " Nami wondered.

Seeming more and more surprised, the knight scratched the top of his helm. Finally, thinking he understood, he asked.

" Are you telling me you got here ... thanks to the Knock-up Stream? ''

"Huh… yes. " Nami replied, dreading his response.

"I can't believe there are people crazy enough to use this monstrous geyser to get up here! It was to prevent this that the Highwest was created. ''

'' WHAT ? ''

Falling to her knees, Nami began to cry.

"Was there a safer route to get up here? ''

Suddenly, taking hold of Vivi's pass, she began to shake her, while roaring.

'' You are a princess who was born on the Grand Line! Why didn't you know? ''

'' It is not my fault. ''

Still looking surprised, the knight noticed the little damage on the Merry, while its new wings had been torn off.

"I see that your boat has indeed had to endure the power of the Knock-up Stream! But, in concrete terms, have you had any human losses? ''

'' No, none. " Luffy assured him, with a big smile. "It takes more to kill us. ''

Immediately, Yosaku and Usopp gave him a double kick in the back of the head.

" Speak for yourself! If Nami wasn't here, we would be dead. ''

'' Highwest ... '' Bruno repeated. "Is it a road that allows us to get here safely? ''

"I can't really say that. " Retorted the knight. " It's a very long detour, which usually takes several weeks and requires a stopover on several celestial islands before reaching Skypiea! Along the way, there is a good chance of being attacked by the creatures that live in the White Sea! As a result, no one can predict whether a crew will be able to arrive at their destination as a whole! For those who use the Knock-up Stream, it's different! Either the crew get here entirely, or everyone dies! Rare are those who take such a risk! I must say that I am impressed by your courage. ''

This time it was Luffy that Nami tried to strangle.

'' It's your fault ! It's your fault ! It's your fault. ''

Preferring to be interested in what this knight might give them, Gin asked.

" What is this money and whistle thing? ''

Rummaging under his armor, the knight pulled out a whistle which he hurled at the crew. Grabbing it, Lucy noticed it was a normal whistle.

"If you're in danger, just blow the whistle! As soon as I hear you, I will come down from heaven to help you. ''

" And will it be necessary to pay 5 million extols? " Sanji asked.

Staring at the crew, the knight looked hesitant. Then, finally, he declared.

"I dare not even imagine the fear you must have felt, coming here! Therefore, to honor your courage, I give you the right to whistle once and I will come to save you for free. ''

'' Wait ! What we want is information about this place. " Johnny told him.

" How do you go about joining Skypiea? " Chopper asked.

'' It's for you to see. '' Asserted the knight, standing up. "Honestly, reaching Skypiea will be a very easy thing, compared to riding the Knock-up Stream! Do you really want to waste your whistle, making me your guide, when greater dangers may arise? ''

Looking at each other, the pirates didn't know what to say. Getting to his feet, the old man asserted.

"I think I'll leave you to fend for yourself! But if you can't reach Skypiea, you can still whistle at me. ''

Seeing him leave, Nami let go of Luffy before asking.

"Sir… what's your name? ''

'' Me ? I am Gan Fall! The knight of heaven. "He announced, before pointing to his bird." And here is Peter, my faithful companion. "

"A knight riding a bird? " Zoro wondered.

"It's not a normal bird. " Gan Fall retorted, leaping into the skies.

Immediately, flying up to him, his steed transformed and took on the appearance of a winged horse.

'' Pegasus? " Lucy and Bruno wondered.

However, instead of the magnificent winged horse, they saw only a rather ugly pink creature. Seeing the result, several people winced.

" He ate the fruit of the horse. " Gan Fall explained to them. " With him, we form a real duo made up of a knight and his steed. ''

Tilting her head to the side, Menma asked.

" Since he can fly and has no land here, what's the point of turning himself into a horse? ''

Immediately, Gan Fall almost fell from Pierre's back, before he retorted.

"A knight without a steed ... that's not a knight. ''

Then, giving the order to Pierre to leave, the duo ends up leaving.

"May luck be with you, my braves. ''

However, stopping, he turned his face, and began to look at a particular person.

" One last tip: never show the color of your wings to the inhabitants of Skypiea. ''

"Huh? " Raynare wondered.

Saying nothing else, the knight left.

" What did he mean? " Menma asked.

'' No idea. " Raynare said simply, starting to regret coming here.

" In the end, he didn't teach us much. " Robin asserted.

'' On the contrary. Bruno retorted, raising several fingers from his hand. " He confirmed the existence of the Sky Island, as well as a way to get there! Moreover, if the inhabitants of a celestial island have managed to design a way to connect the blue sea to the white sea, then that means that we will potentially have a way to leave the celestial island and return to the bottom. ''

'' It's true. " Vivi asserted. " Also, it looks like we only need the money to keep ourselves safe. ''

'' Because you think we have some? " Nami growled. " We are broke. ''

" Raynare has money. " Lucy retorted. "We still have part of Arlong and Alvida's treasure, as well as Morgan's piece of gold statue! In the end, maybe it will be of use to us. ''

Grumbling too, Raynare finally retaliates.

" Didn't you hear what he said? Here, the money is called Extol! If it is, even gold has no value here. ''

" So there is no question of wasting our whistle unnecessarily. " Sanji remarked. "The knight can serve as our guide! But in the event of a problem at Skypiea, we will have to pay it! But if we have nothing, he will never help us. ''

"Because you think we can really climb higher, without his help? Zoro asked.

" You have to ask him. " Luffy asserted, grabbing the whistle.

Seeing him about to whistle, Nami and Usopp began to grab hold of him and strangle him to keep him from wasting their whistle.

'' Asshole, stop it! You have just been told that we must not use it, except in an emergency. ''

" If the masked guy comes back, we're in big trouble. ''

Groaning at hearing of him, Raynare showed her anger.

"Raynare, is your back okay? " Chopper asked her.

'' Yeah yeah. " She replied dryly. "My fallen angel body will heal in minutes! Instead, let's find a way to get out of here. ''

"Why don't you go that way? " Robin asked, pointing in one direction. "Have you seen this strange cloud? ''

Approaching her, the rest of her teammates spotted a waterfall-shaped cloud, which was visible in the distance.

'' A waterfall ? " Yosaku wondered. " Do you really think joining her will solve our problem? ''

'' Do you have another idea? " Zoro questioned, already heading for the helm. "Nami, are we going? ''

With a simple weary sigh, the redhead finally gives her approval.

'' Yes ! Anyway, if we stay here, I'm afraid the masked man will come back with his comrades.

Whistling merrily, a man was fishing, while watching the float of his fishing rod float above the sea of clouds.

'' What a beautiful day. Pit asserted, as he sat down on a white beach, made from clouds. ''

Being drinking, Shanks was laughing, as he started to get drunk.

"HAHAHAHA! Yassop, fill me another glass of alcohol! It's an order from your captain. ''

"HAHAHAHA! At your command, captain. " The sniper assured, filling his glass.

Nevertheless, ceasing to smile, the two men felt a murderous aura, while Nana was in front of them.

"Shanks… what did I say about your binge drinking? ''

This is my first drink. The man assured, despite the fact that there were already three empty rum barrels behind him.

Preferring to run away, Yassop was discreetly walking away. Nevertheless, grabbed him by the back of his clothes, Nana asserted.

'' Yassop! I also ordered you to calm down your alcohol consumption! So why are you drunk? ''

"Huh ... I ... I ..."

"Captain. ''

Approaching the trio, Beckman looked serious as he declared.

'' He is coming. ''

"Huh? Shanks said in surprise, getting ready to drink another glass of alcohol. '' Who are you talking about ? ''

'' Aizen! ''

Immediately, all the pirates around the quartet heard a shattering glass, while Shanks had clenched his fist so hard that his liquor glass had been shattered into pieces. Feeling veins of rage appear on his forehead, the captain exhaled at length. Then, regaining his composure, he ordered.

'' Get ready! Party time is over! And get ready to fight! At the slightest suspicious movement on his part, kill him. ''
