Start by Eating Jake Jake no Mi

"Oh, I can use it too!" 

Perona looked at herself, who had become a wolf, in amazement before she quickly took off the jacket made from the Inu Inu no Mi, Model: Model. 

"Why did you take it off?" Masa asked curiously. 

"It's too ugly." Perona had an uncomfortable expression when she thought of a wolf version of herself, which made Carina and Kalifa nod. 

Before Perona, the two of them had tried the jacket made from the Inu Inu no Mi, Model: Wolf, and they could feel the improvement in their physical ability, which was amazing, but then again, it was too ugly somehow. 

"....." Masa. 

"I am fine with the Horo Horo no Mi." Perona felt that her Devil Fruit was good enough as it could help everyone monitor their surroundings to remind them whether spies or other people were entering their place. "But if there is a different Devil Fruit, let me try, Masa." 

Masa had the ability to turn a Devil Fruit into a jacket, which allowed those who had eaten a Devil Fruit to have another Devil Fruit, so Perona wanted to try those Devil Fruits as it was fun. 

Still, while Perona didn't care about how Masa had such an ability, Kalifa was so curious, but she held it since if Masa talked, then he would talk, but if he didn't, then she could only wait. 

Nevertheless, Carina nodded at their reactions before she asked, "Where did you get that Devil Fruit?" 

"CP9 agents." Masa played with the Devil Fruit on his hand and said, "Do you remember when I talked about the ancient weapon on the bar before? That night, those agents suddenly came to him, and I beat all of them, taking their Devil Fruit." 

"Oh." 2x

While Carina and Perona nodded, Kalifa was speechless, realizing that Masa was the hunter all along. 

"Wait!" Carina suddenly realized something and asked, "Is there an agent on this island?" 

"Kalifa is an agent." 

"..." Carina and Perona. 

"I am his woman now," Kalifa said calmly, clearly accepting her fate. Anyway, it wasn't bad to stay with Masa, especially when he didn't lack anything and he was strong. More importantly, he also happened to be her type. Instead of fighting and resisting, she might as well be his woman obediently since it was more enjoyable than being an agent that made her need to work so hard. 

Kalifa also wanted to rest, okay? 

However, unlike in the future when the work was limited to five, in the world of One Piece, the workers were expected to work every day for more than 12 hours or more daily! 

While Kalifa was used to such a schedule, she had to say that living like Carina and Perona was much better. 

Having a good man to rely on, Kalifa thought this was the best path of her life, especially when she knew Masa planned to become an admiral. 

Nevertheless, there was no doubt that everyone understood why Masa could control a cat, and it was probably due to the Neko Neko no Mi Model: Leopard from Rob Lucci. 

Still—

"Kalifa, do you think your boss has a Devil Fruit?" Masa asked. 

After joining Masa, Kalifa told everything about the CP9, including their purpose, which was to get the blueprint of the ancient weapon, the members of the agent, headquarters, and everything. 

Yet, aside from the ship, Masa was more interested in the Devil Fruit that could be gained from the CP9. 

'Oh.' 

Now, Carina understood why Masa had mentioned that she would get her Devil Fruit soon. 

"I am not sure whether it is counted, but my boss should have a sword that ate a Devil Fruit." 

"A sword that ate a Devil Fruit?" 2x

Carina and Perona looked at Kalifa with doubt; after all, it was common sense that only a living being could eat a Devil Fruit, so how could an item, a non-living being, or a sword, eat a Devil Fruit?

"I am not lying." Kalifa rolled her eyes and said, "It can turn into an elephant, so it should be eating the Zou Zou no Mi, Model: Elephant." 

Yet, as the three women talked, Masa fell into a deep thought. 

'This technology that allows a non-living thing to eat a Devil Fruit... isn't it like a Sacred Gear?' 

Yes, Masa thought it was the same since the Sacred Gear was an item crafted by the god of Christianity that combined a non-living thing, such as a weapon or other item, with a supernatural creature. 

The sword that was mentioned by Kalifa, owned by her former CP9 boss, was such a weapon as it had eaten the Zou Zou no Mi, Model: Elephant, so it could transform into an elephant or give an elephant-like feature to the animal. 

The Sacred Gear was similar since it could allow the user to use the innate abilities it originated from. 

The best example would be the "Boosted Gear," which was crafted from the Welsh Dragon, Ddraig, which allowed the user to access the power owned by Ddraig during its life. 

If Masa had to say, in the world of One Piece, it would be like letting a non-living being eat the mythical type of Zoan. 

In the case of the Hito Hito no Mi, Model: Nika, it could be put into a weapon, then it could make the weapon, and the user could stretch like rubber, and when it reached an "awakening," it could allow the user to control the terrain. 

'It's a bit similar to my ability to turn a Devil Fruit into a jacket, huh?' 

Yes, instead of turning the Devil Fruit into a jacket, which allowed one to wear the ability as they pleased, this technology that allowed a non-living thing to eat the Devil Fruit was similar. 

Nevertheless, this technology... Masa felt like it could be used in another world, too, especially in the world of DxD, where supernatural beings existed everywhere. 

Or rather, if Masa had discovered the corpse of Satan, then it might even be possible for him to combine that corpse with a weapon, turning it into a Sacred Gear. No, it should be a Longinus, considering it was created from the body of Satan. 

So, in the world of DxD, while devouring the corpse of powerful supernatural beings was the best way for all of them to become stronger, crafting something by using those corpses was also quite a good method to become stronger and, more importantly, such items could be used by his followers, especially the peerage members of Masa DxD such as Asia. 

He might have been able to get the data of this technology by hacking the Punk Record, but he wanted to get his hands on the real thing to make a comparison and, more importantly, to develop this technology further since if Zoan Devil Fruit was possible, then other Devil Fruits should be possible, right? 

As Masa thought so, he couldn't stay lazy like this. He had made up his mind to get the sword of Spandam, the chief of CP9. 

"Kalifa, let's go." 

"Huh?" Kalifa was confused. "Where are we going?" 

"Let's get this sword." 

"..." Kalifa fell silent and persuaded Masa softly, "This sword should be placed in the Enies Lobby, one of the World Government's three major strongholds." 

"Yeah, it will be fine." Masa put on his clothes and then carried Kalifa on his arm. "Carina, Perona, we will go back soon." 

"Wait! Wait! Let me put on my clothes first!" 

"Oh, right." 

After putting on her clothes and sighing, Kalifa quickly left with Masa to go to the Enies Lobby helplessly. 

Nevertheless, Carina and Perona looked at each other for a moment. 

"Should we go shopping?" 

"Okay." 

Yet, as Masa and his group were enjoying their stay on the Water 7, it was different from the others, who were rather gloomy due to their appearance. 

But so what? 

As always, the number rule of this world was simple: the weak had no rights, and the strong got everything. 

In front of overwhelming power, all the people on this island, whether they loved it or not, could only succumb. 

Yet, more importantly, if one was weak, they should know their place and not provoke him. 

Masa might love peace, but if someone troubled him, then don't blame him for being ruthless.
