Start by Eating Jake Jake no Mi

"Impel Down?!" 

After Kalifa and Perona returned with a lot of food, Masa started to eat calmly as he talked about his Yami Yami no Mi's power, which he didn't hide from the two. 

"....." Kalifa and Perona. 

Naturally, the two were dumbfounded when they saw him wielding such new power, but as their man had become more powerful, it was a happy event than a sad one, yet there was no doubt it brought them a shock as it was their first time to know that a man could eat several Devil Fruits at the same time. 

However, this also strengthened their desire to be with him more since the stronger he was, the better it was for all of them, right? 

Yet, there was no doubt after Masa explained his power, Kalifa was at a loss when she heard about his next destination. 

"Impel Down?" 2x

Unlike Kalifa, Carina and Perona looked at Kalifa with confusion as Kalifa showed such a strong reaction.

Impel Down was just a prison, right?

Why did you show such a strong reaction? 

"..." Kalifa. 

Masa only smiled and said, "It's like the Enies Lobby; it is one of the strongholds of World Government." 

"Er... what is the problem?" Perona was confused and said, "Didn't you two just visit the Enies Lobby with ease?" 

"..." Kalifa. 

"That's true, but unlike Enies Lobby, Impel Down is an inescapable prison, and no one has escaped from this prison." 

"Inescapable? Why?"

"Because it was built underwater, in the middle of the Calm Belt!" 

"Calm Belt..." 2x

When Perona and Carina heard those words, they also understood why no one could escape from this prison. 

Calm Belt is the two areas of the ocean that border the north and south of the Grand Line. 

If there is something special about it, these areas are always completely calm, never having any ocean currents or winds blowing, making it impossible for non-self-propelled ships to travel through. They also happen to be the nesting grounds for the world's largest sea kings, which attack any ship attempting to cross over.

As most ships moved by sails, most of them would definitely die as they passed the Calm Belt. 

Not only they couldn't move as there were no winds, but they would also be hunted by the sea kings, a large type of fish that could reach a hundred meters or more in size. 

For a prison to be built on such a place, no criminals could ever escape from that place unless they got their hands on the ship of the Marines that was coated by a seastone underneath or had a Devil Fruit ability that allowed them to fly. 

"Oh, right, there was one person who could escape from that prison." 

"Who?" 

"Golden Lion, Shiki."

"...who?" 

"...." 

Masa looked at the three young women and understood why they didn't know who Shiki was. "He was a famous pirate from the same generation as Gold Roger and Whitebeard." 

"...." 3x

"If I am not wrong, his Devil Fruit is Fuwa Fuwa no Mi." 

"Fuwa Fuwa no Mi?" 

"It's a Devil Fruit that allows the user to make anything he wishes to float, including himself." 

If Masa had to say, it was like telekinesis, which was a pretty neat ability. If he didn't have Ton Ton no Mi, then he might aim for this Devil Fruit, but as he had Ton Ton no Mi, if he ate Fuwa Fuwa no Mi, it wouldn't give him much of an improvement in strength, and he had already made up which two Devil Fruits he would eat, to complete a total of eight Devil Fruits that he could eat. 

"...is that a dangerous ability?" Perona tilted her head, which made Masa speechless, and said, "Let's say that he makes an island float, then throws it to you. Is that dangerous?" 

"...." Perona. 

Okay, Shiki was quite strong, she thought, but Moria and Masa were stronger than Shiki, she thought. 

"So, why do you want to go there? While you have said that our ship can pass the Calm Belt previously, do you really need to go to such a dangerous place?" 

Carina didn't think the Calm Belt was a dangerous place, especially when Masa had told them that their ship was coated with seastone so they could pass the Calm Belt without worry, without being noticed by the sea kings, but even if they were noticed, Masa was strong enough, but what was the point of provoking the World Government? 

If it was before, like on the Saobody Archipelago, where they were targeted by an admiral, or like to take the Devil Fruits from the Enies Lobby, then Carina understood, but what kind of benefits that Masa could gain from the Impel Down. 

Masa didn't answer that question immediately but took out a single Devil Fruit in front of them. 

"...Devil Fruit?" 

"Did you get another one?" 

"....." 

They had to admit that Masa's luck was as great as ever since if one might not be able to get one in their entire lives, he could get it with ease. 

"Do you know what kind of Devil Fruit is this?" 

"No."

"What is it?" 

"Ushi Ushi no Mi, Model: Bison." 

"....." 3x

"The one... that was eaten by that stupid cow?" 

"Yes." Masa nodded and said, "By using the power of Yami Yami no Mi, I can absorb the Devil Fruit from the user." 

"..." 3x

"Impel Down is a place full of the cruelest, most vicious, and strongest criminals who are kept. In that place, there are also many who have eaten the Devil Fruits there, so you understand, right?" 

Naturally. 

All of them nodded and understood why Masa wished to go to Impel Down. 

No, if that was the case, then there was nothing wrong with them going to Impel Down, especially when the Marines were busy with the preparation for the admiral competition to choose the new admiral to replace Kizaru, who passed away. 

"Okay, why not? Let's go there." Carina agreed without hesitation since she knew the importance of the Devil Fruits well. Even if they couldn't eat them, it would be good for their children and followers. 

'Children...' 

Carina blushed shyly and hurriedly shook her head. 

"I know that it might be late to say this, but you can eat more than one Devil Fruit?" Kalifa asked with reverence. 

"Yes." 

Compared to all the secrets that Masa had kept, this secret was nothing. 

"....." 3x

"There is also one Devil Fruit that I need the most there." 

"Okay, even if it's dangerous, it doesn't matter." 

If Masa had said that this Devil Fruit was the one that he needed the most, then even if they had to fight the World Government, it didn't matter, especially when their confidence rose to him even further after knowing that he could eat more than one Devil Fruit. 

"Okay, let's go now. If we go now, we might be able to go back before the dinner." 

"...can our ship move so fast?" 

"I have never said that we will go by a ship, right?" 

"Oh, right." Carina moved closer to Masa's back and said, "Don't fight back, okay? Let me open the door on your body." 

"..." Masa. 

Still, he followed Carina's words, and the door opened behind his back, which Carina entered. 

"....." Perona and Kalifa. 

"Come on," Carina looked at the two and urged them to enter. 

The two were still shaken when Carina opened Masa's body with a door, but they could think about that later since they would be lying if they didn't feel curious about Impel Down. 

More importantly, how did they get to Impel Down? 

"Carina, can you open the door to Impel Down?" Kalifa asked curiously. 

"...who do you think I am? I never knew this place before he even told me, okay?" Carina was speechless, then said, "But if it is a Water 7, then it might be different." The Doa Doa no Mi suited her well, and after she got this Devil Fruit, she could mostly go to any places that she had been to. 

At the same time, this also made her think of the thief, who had worked with her on the East Blue in the past. 

'Should I visit her?' 

If it was in the past, Carina might not think about that girl, but she felt that she owed something, and she, who had seen the world, felt that the pirates on the East Blue were too weak, but let's talk about that problem when Masa finished his goal. 

So, as the three entered his body, Masa thought to tell Brook, Chopper, and Kureha that he would leave for a while. 

But—

"How dare you say something so rude to the princess!" 

"I am just asking the color of her panties! What's so rude about that?! It is a gentleman's etiquette to ask about a lady's panties!" 

"....." Everyone. 

"...what's wrong?" 

When this voice fell, all of them became quiet, and they greeted him respectfully. 

"Masa-sama!" 

The man with a weird hairstyle quickly became tense when Masa appeared, but the young woman with light blue hair slammed her head to the ground and begged with all of her might, "PLEASE SAVE MY KINGDOM!" 

"....." Masa.
