Okay, since someone found the reference, I have to admit that Hyou's arc is a re-adaptation of one of the Murcielago manga arcs. I admit that I like this manga (it is sixth in my personal ranking) even if there is no French version. And to be honest, the arc where Isuka and Ace meet is also a adaptation of the same manga. Since you asked me about the appearance of new characters, I had to cheat in this way (the introduction of Isuka in the story was made three days after one of you made me demand) and so I had the idea to use a little known manga. I plan to use it again in arcs where Luffy doesn't appear.

Having many pieces of debris in his hands, Snake threw them in several directions and let them hit the walls and the ground. However, contrary to what he thought, nothing happened.

"Strange! Could the reception hall be the only room trapped?"

"I would be very surprised if that were the case." Cavendish retorted. "After all, don't forget that this guy invited a logia among his guests! It would be stupid of him not to have planned anything to kill him, in case he used his powers to escape the traps."

For his part, having given up his guitar and sunglasses, Ace hadn't bothered to hide his identity any longer. However, as the group of survivors had just left the reception hall and walked down a long hallway, the pirate could feel many eyes aimed at him.

"Tssss! When I think I'm finally getting the chance to kill you." Cavendish growled. "If that stupid psychopath hadn't appeared, I swear I would have had your head by now."

"Remind me to thank Hyou for that." Ace said, barely interested in what he was doing.

Tapping one of the walls with the back of his hand, Moyo turned to the pirate.

"This wall is not trapped! Why don't you use your powers to pulverize it?"

"I already thought about that..." Ace affirmed, putting his hand on the wall. " But ... "

Immediately, he felt his strength being taken away from him and he quickly withdrew his hand.

"These walls, they have a layer of Seastone in them."

"So the owner of the place didn't do things by halves." Snake understood, putting his hand under his chin. "Ten years to build this mansion? He had to think of I don't know how many things to make sure no escape could happen."

Following them, while drinking a glass of wine, Cordio only directed his gaze towards one of the group members.

"Vice-Admiral Karly! I'm surprised to see a man like you among the guests."

"I see I'm famous." Karly said casually as he had his hands in his pockets.

In truth, the man put on a bored face, when the situation barely seemed to concern him. Showing no seriousness in his gaze, he seemed to act in a manner contrary to that of his famous father.

"Of course! After all, you are one of the Navy's five hopefuls."

"Five hopes?" Moyo repeated.

"These are the five people predestined to replace one of the admirals, should the need arise." Snake told him. "These are Vice Admiral Garp, Vice Admiral Emma, Vice Admiral Fujitora, Vice Admiral Ryogukyu and...Vice Admiral Karly."

"Yeah, that's me." Karly agreed. "But if I'm here, it's definitely not because I'm a villain! In fact, I had to pose as corrupt in order to be invited."

"Tssss! That lie is really stupid." Cavendish retorted. "Why do you want to attend this party?"

"Because it's not the first party this place has had." Karly affirmed. "Within the Navy, I am the leader of the group in charge of ensuring respect for the code of honor of the Navy within the various fleets! Among the soldiers, I was responsible for spying on some of them , who were suspected of corruption or selling arms! However, most of them suddenly disappeared! And they had one thing in common! Among the belongings of several of them, we found an invitation An invitation to a party that was happening here."

"So you..." Snake began.

"Yes, I was assigned to come here to conduct an investigation, and now I must confess that Hyou has become my number 1 suspect! However…"

Turning to Isuka, he declared.

"I must admit that you were not one of my targets! Would you have managed to deceive my vigilance?"

"No!" Isuka retorted. " I ... "

Suddenly, she felt Ace's hand pat her head several times, while he smirked.

"This girl is trying to capture me."

"Huh?" Karly wondered.

"Since the day we met, she keeps chasing me trying to kill me but... she always failed."

Turning his arm into flames, he asked.

"After all, what can she do against me when she can't master haki?"

"And you let her chase you without trying to kill her?" Moyo wondered.

"Why would I? I have to admit that I really enjoy ridiculing the Navy! As long as it doesn't have a seastone with it, it's harmless.

" Grrrrr ! " She growled.

Even though she knew Ace was saying that to protect her, she couldn't hide her frustration that he was right: even if she wanted to, she could never catch pirates like Ace. Finally, she declared.

"I tracked Ace down here and hoped I could meet some high-ranking Navy people to help me capture him! However, things didn't go as planned."

Starting to count on his fingers, Moyo said.

"I'm a mercenary! And there are two pirates! A mob boss! Two Navy soldiers! And..."

He turned to Snake.

"Why were you invited?"

With a sigh, the man declared.

"Years ago I was in a band and an assistant to one of the most famous people in this world: Vegapunk."

"VEGAPUNK?" Several people wondered, turning to him. "You worked with Vegapunk?"

"You overestimate me." Snake retorted. "Like I said, I was just an assistant! The real scientists who worked with him only saw me as someone barely worthy of cleaning up their equipment."

"But what does it have to do with your being here?" Cavendish asked. "Vegapunk is believed to have saved thousands of lives with its inventions."

"I don't know if you're unaware of this, but before allowing anyone to be able to obtain an invention, it must be tested! And for that you need guinea pigs! And sometimes... you need human guinea pigs. "

Remembering various prisoners screaming and trying to struggle, he asserted.

"When I entered in the scientific world, I was sent to Punk Hazard, and it was there that I discovered the hidden side of science! To be able to make people's lives better, you have to sacrifice some."

" So, Vegapunk and his team killed thousands of people and since you worked with them, Hyou considers you one of their accomplices. " Ace understood. "And since you worked with Vegapunk, that's why your name was unknown to everyone."

"That's right! Even working two years with him, my life was so secret that no one outside the island knew who I was! Normally, no one should be able to name the names of people Vegapunk has rubbed shoulders with! Bad people might try to kidnap me so that I tell them all the secrets of Vegapunk."

" But then, how did Hyou know? " Isuka asked.

"Probably because of his money." Karly affirmed, yawning. "When Vegapunk worked at Punk Hazard, he was working in partnership with the Navy! If Hyou found a soldier who was on the island and managed to pay him enough, I'm sure he could get all the information That he wanted. "

"Tsssss! This guy has no scruples." Moyo growled.

" I don't want to hear that from the mouth of a bloodthirsty mercenary. " Isuka retorted.

"HEY! I'm not a psycho." Moyo retorted. "It's true that I accept contracts! Especially contracts from countries being at war and looking for mercenaries to defeat the soldiers of the opposing country! Yes, I have killed many people, but it was not only during my contract periods! When I'm not on a mission, I don't kill anyone."

"And do you think that makes you forgivable?" Isuka retorted.

"I don't see the harm." Moyo retorted. "Honestly, what is the difference between a soldier from a country at war and me? When this soldier kills an enemy of his country, he is not considered a murderer! And yet, that is the case with me because that I'm not a citizen of this country! That's pretty hypocritical."

"It's not just that." Retorted Karly. "There was also the Foxtown carnage where you slaughtered a dozen Navy soldiers."

"Tssss! These assholes wanted to hold me responsible for several crimes only so that my arrest could allow them to have a better rank! I made them understand that they should never take me for an idiot."

Turning to Cordio, he declared.

"This guy has done much worse things than me."

"Why suspect me?" Cordio asked innocently. "After all, if I was a criminal, I'm sure the Navy would have tried to capture me."

Smiling then, he asked.

"Are you suspecting me of bribing a few people to be quiet?"

"Tssss!" Isuka said, displeased.

"And you?" Moyo asked, looking at the last member of their group. " Why are you here ? "

Startled, the second girl in the group couldn't help but calm her trembling as she confessed.

"I came with my brother and...he was making money selling weapons illegally."

"Are you arms dealers?" Cavendish wondered.

"It was just a few weapons." The girl asserted. "I... besides, I only helped him to carry out some negotiations! I didn't do anything wrong."

"Idiot." Karly growled. "Selling guns illegally means that the people who buy them intend to use them to do bad things."

Glancing in the direction of the teenager, he asked.

"Do you know how many people died because of those 'few' guns you sold?"

Not knowing what to answer, the teenager lowered her head, before mumbling.

"So ... Sorry."

"In truth, few of us can afford to believe ourselves better than others." Ace remarked. "But me, what I want to know..."

Turning his gaze to Karly and Cavendish, he declared.

"I admit I don't know if we can team up."

"Tsss! Like I said, I'm going to kill Hyou first, and then I'll take care of you." Cavendish assured.

Yawning, meanwhile, Karly declared.

"I admit that being forced to fight you is not really one of my priorities! Besides, I already have a mission to carry out! I am not motivated to accomplish another one at the same time. "

Looking at him, Isuka couldn't hide her astonishment at the man's laziness. She had never met Akainu, nevertheless, she knew perfectly the character of the man who, in her eyes, always defined the sense of her justice.

Before meeting Ace, her vision of perfect justice had always been instilled in her by Akainu's actions and his burning desire to want to make all the pirates on this planet disappear.

Still, if Isuka had to guess Karly's father, she would have bet on Aokiji, rather than Akainu. Karly didn't seem to have inherited her father's seriousness at all.

Noticing that too, Ace couldn't help but stare at the man, wondering if he could really consider him an ally. Seeing him walking close to him, the pirate saw the vice-admiral put one foot on the ground. And immediately, a strange noise was heard.

The noise was minimal and the duo seemed like the ground to have heard it. However, the next moment, Karly jumped back and avoided getting stabbed by several spikes that popped out of the ground. Stepping back too, Ace felt one of the spikes brush against his cheek and hurt him slightly.

"Seastone?" He wondered, landing on his feet.

"Tsssss! The traps we're about to encounter will be more dangerous than those in the party hall." Cavendish understood. "Hyou wants to kill everyone, including Devil Fruit users."

Suddenly, Moyo turned to him, and gave him a powerful kick in the abdomen. Spitting saliva, Cavendish slammed into the wall behind him, before grabbing his sword.

" YOU ... "

However, part of the ceiling suddenly disappeared and a liter of green liquid fell on the floor, where Cavendish was. And in an instant, the carpet that covered the floor, as well as the parquet began to melt, while the liquid disintegrated everything it touched.

"Acid." Snake noted, turning to Cavendish. "You almost died."

Still holding his sword, Cavendish groaned again, turning his face away from Moyo. And instead of thanks, he asked.

"How did you know it was going to show?"

Showing his ears, Moyo affirmed.

"When you're a mercenary and you spend your life at war, your senses develop! My hearing is five times more developed than the average! It allows me to hear noises that no one else can hear."

Turning then to Karly and Ace, he declared

"You have very good reflexes! I must admit that I barely had time to hear the mechanism of the first trap! A normal person would have been killed."

"Navy training." Karly affirmed, still looking bored.

Suddenly, a submachine gun appeared behind the man and pretended to fire. Nevertheless, a revolver bullet disappeared inside the firearm, before detonating it. Finishing his drink, while having one of his revolvers in hand, Cordio displayed a serene smile, while affirming.

"52 years of shooting training! I could hit a mouse in a sandstorm."

"Su…Sugoi." The arms saleswoman said, seeing the men around her. " You are incredible. "

"And you, what do you know how to do?" Isuka questioned her.

"Huh...?" the blonde said, not knowing what to say. "I don't know how to do anything."

Seeing her about to sob again, Isuka sighed and asked.

" What's your name ? "

"Ya…Yank." The blonde said.

"Yank...I too disapprove of what you did! Even though you only sold a few guns, what you did may have cost many people their lives."

Not knowing what to answer, while she lowered her gaze, Yank saw Isuka seize the hilt of the sword and violently strike another submachine gun that had appeared behind Yank. Making quick movements, Isuka returned her weapon to his belt, while the submachine gun had been transformed into a colander.

"Stay close to me." Isuka ordered.

Having barely had time to see her act, Yank immediately nodded, before following the lieutenant.

Having resumed walking, Snake stared at the hallway walls, declaring.

"The door through which we entered this place has been sealed, as have the windows! And brute force or the powers of a logia have no effect! Clearly, Hyou has blocked us here."

"Really?" Cavendish asked, sarcastically. "I hadn't noticed it."

"Don't you understand what I'm trying to tell you?" Snake asked. "We move through this mansion hoping to find Hyou but... who tells us that he hasn't fully sealed off the part of the mansion we are in? For example, if we get stuck in this hallway, we we'll have no way of escaping."

" Don't worry about that. " Ace retorted. "We will meet him once we destroy all his traps."

" Huh ? "

" I saw the joy on his face, when he saw people die. " Affirmed Ace. "He doesn't want to give his victims a chance and he wants to see them die brutally and through one of his traps! So either he'll be happy to see us go through or whatever...or he'll be happy to see us die right in front of him! I'm sure he's waiting for us, with a little surprise for us! Plus, with his power, he can afford to let us get close to him."

"Maybe..." Snake said. "But judging by his sadism, he might also be content to see us die for a few days, leaving him stuck here until death ensues."

" I know men like him. " Ace retorted. "He's not the kind of person who favors torture! What he wants is to see us dead! Someone like him would be the kind of person who would get annoyed easily, if he decided to waiting for our death by blocking us in a place where we will not be able to escape and be obliged to watch ourselves for several days. "

"That remains to be proven." Snake stated. " In any case ... "

Suddenly drawing a dagger from one of his sleeves, he used it to strike a painting that hung on a wall. Feeling his weapon sink beyond the paint, he finally pulled out his dagger, as his blade had skewered the paint, as well as the body of a den-den mushi, which was hidden just behind it.

" Hyou nous observe. " Affirma Snake.

Indeed, despite being discovered, Hyou laughed, while seeing Snake's face staring at the den den mushi. Then, finally, the image disappeared, while the snail finally succumbed to its wounds. Regardless, Hyou stared at the hundreds of screens in front of him, matching the number of den den mushi he had concealed inside his mansion.

" Kahahahaha! No matter what you do, you won't be able to hide! Because I know exactly where you are doing! And even if I was blind, I know this mansion so well that I know what traps you will have to face. "

Then, thanks to another den-den mushi filming Ace's group, while he was stuck in the ceiling, Hyou looked at the pirate's face, as he could hear what he had said to Snake.

"Indeed! I am not someone who likes torture! I take no pleasure in seeing people suffer in front of me."

Then putting on a hateful face, he declared.

"All criminals must be eradicated immediately! None of them deserves to live an extra second, even if it is to be tortured! The mere fact that they can breathe the same air as ours is an unforgivable act. "

"Indeed, master." Assured Kamy, who was standing behind him.

Regaining her composure, Hyou then smiled, while affirming.

"He's also right that I have something in store for them, if they manage to get here."

Turning to Nodeath, he questioned him.

"If Ace gets this far, will you be able to kill him?"

" Don't ask me that question, Hyou-sama. " His bodyguard retorted.

Fixing Ace, while mounting a certain hatred in his gaze, the man assured.

"I will destroy him no matter what! And there will be nothing left of him when the slaughter is over."

Chuckling grimly, Hyou declared.

"I can't wait to see the corpse of that cursed pirate at my feet! It's not something anyone could brag about."

"Now what do we do?" Moyo asked.

Having reached the end of the hallway, the group saw that the hallway split along the way. One was going left and the other was going right.

"The path splits in two." Snake remarked thoughtfully. "Do these two paths allow us to reach Hyou or will one of them continue us to certain death?"

"What do we do?" Yank asked.

"Our guest went out of his way to throw this party." Cordio affirmed. "In that case, let's be good guests and make sure we destroy each of his traps! Let's split into two groups of four."

"And how do you want to form these groups?" Cavendish questioned.

Simply stepping forward, Ace asked.

"Who wants to go right and who wants to go left?"

"LEFT!" Isuka, Moyo, Karly and Cavendish said, pointing in the direction.

"RIGHT!" Snake, Cordio and Yank said, imitating them.

Seeing the composition of the two groups, Ace declared.

"I'll go right with Yank and the others! Moyo, take care that Isuka and Cavendish don't mess up."

"Why are you treating us like children?" The duo roared.

Simply smiling, Ace headed for the right path, immediately followed by Yank. However, quickly ceasing to smile, Ace discreetly looked behind him.

Following him without a word, Snake continued to stare thoughtfully at the walls as he seemed to think about ten thousand different ideas in order to get out of this place. Cordio, meanwhile, walked forward with a wicked grin on his face, as he looked like he was ready to stab Ace at any moment.

Ace didn't like leaving Isuka alone but he didn't want to leave Yank with this duo. Isuka could defend herself, compared to the teenager who was overwhelmed by events. strangely, Ace trusted Moyo more than he trusted Snake. As for Cordio...he knew he couldn't trust this guy at all.

Nevertheless, he knew that the duo behind him was made up of two very intelligent people. With a little cooperation, they could prove to be of great help.

However, suddenly stopping, he said to the other group.

"Stay alive."

Receiving no response, he didn't see Moyo smile with conviction as he knocked his fists together. Cavendish growled again, grabbing his sword. Yawning one last time, Karly cracked the muscles in his neck, before putting on a much more serious look. And finally, Isuka whispered.

"You too...stay alive."
