Start by Eating Jake Jake no Mi

"So, you have eaten three Devil Fruits?" 

"Yup." 

"Ton Ton no Mi aside... you devoured Kizaru?" 

"Yup." 

"..." Masa from DxD and Mahouka. 

After the three of them entered the space, Masa from DxD and Mahouka naturally knew about the fight of Masa from One Piece against Kizaru, yet even so, hearing it from the mouth of Masa dumbfounded them since wasn't this guy too unlucky?! 

Yes, the two had never thought that Masa from One Piece could devour Kizaru as luck; instead, this guy was too unlucky! 

After all, not only was this guy almost being sold as a slave, forced to fight on the first day of his transmigration, then lastly, he had to fight the admiral! 

Damn, what was wrong with this guy's fate?! 

Fortunately, this guy had Carina on his side, or else, there was no doubt, he would be stressed. 

At the same time, Masa, from the world of Mahouka and DxD, couldn't help but think how lucky their lives were. 

Whether it was Masa from the world of Mahouka or DxD, the two of them had their share of fights. 

Rather, Masa, from the world of Mahouka, had even joined a war against another country in the past. 

Yet, even so, the two of them never fought against those who were stronger than them, and the two of them had quite good backing that could protect them. 

On the other hand, Masa from the world of One Piece had to fight the impossible, and this guy had no backing! 

Still, at the same time, hearing the cause of his fight, the two of them supported him since if their women were treated the same way, even if they had to fight the impossibility, they would do it since it was related to their pride as a man. 

Even if they had to enter hell by fighting a powerful opponent, they wouldn't let their women be molested! 

Yet, they had to say that Masa from the world of One Piece was amazing for being able to develop the Jake Jake no Mi into such a powerful ability, and naturally, they also benefitted a lot from it, which was good. 

"Thanks, Masa from DxD; if you hadn't trained your physical ability, then I might not be here today..." 

If Masa from the world of DxD's focus hadn't been on physical ability, then Masa from the world of One Piece knew that his battle wouldn't end so soon. 

"It's fine." Masa from the world of DxD shook his head and said, "I do this because I need to protect myself." As a devil from the Vapula family, his innate ability was limited. Learning magic might be a good choice, but it lacked power, and the importance of physical ability was higher in the world of DxD. 

Sairaorg, who was known as the weakest devil and lowest potential, could become one of the most powerful due to training on his physical ability, so Masa, who was known as the highest potential of the Vapula Devil, naturally, could do better, especially with the amount of his Demonic Power being comparable to an Ultimate-Class Devil. 

Still, in the world of DxD, if one wanted to become strong, one had to have a Longinus, so there was no doubt that Masa was a little helpless, especially when he had no ability to use Longinus. 

Fortunately, he had this ability, which allowed him to share everything with all the other Masas from another world. 

"By the way, when I recover, I will try to get that Devil Fruit." 

Masa from the world of DxD was startled and quickly said, "No, no. It's fine. You don't have to worry. You should go and rest now. Moreover, you have eaten three Devil Fruits, right? We have hit our limit. Let's wait till the next Masa comes again." 

If Masa from the world of One Piece wanted to devour more Devil Fruit, another Masa had to come out, or else, Masa would explode and die. 

If Masa had just died, then it would have been okay, but what if he had lost all of his abilities? 

Jake Jake no Mi, Ton Ton no Mi, and Pika Pika no Mi. 

While the combinations of those Devil Fruits were weird, there was no doubt all of Masa had become stronger, especially after Masa from One Piece was able to devour Kizaru. 

"I will try to develop the Ton Ton no Mi here." Masa from the DxD had nothing to do anyway, and there were hardly any problems in his life, considering he had been staying in the Underworld, so he thought of developing the Ton Ton no Mi. 

As for why Ton Ton no Mi instead of Pika Pika no Mi, it was because it would be wasteful if one didn't develop this ability, right? 

Anyway, they had this ability, so it was natural for them to develop it instead of wasting it. 

More importantly, as they had said before, the potential of the Ton Ton no Mi wasn't bad at all, even if they had to say they felt a bit regret about eating this Devil Fruit, considering the three limited Devil Fruits that Masa could eat, there were many Devil Fruits that could give them a better potential. 

"Still, Ton Ton no Mi is a power, and Pika Pika no Mi is a speed. The combination of speed and power isn't bad at all." 

Masa from the world of One Piece sighed, then said, "What is left is for the improvement of physical ability, especially vitality, endurance, and stamina." 

So, in case the next Masa appeared, his choice of the next Devil Fruit was obvious. 

"Still, I am sorry for not being able to help much." Masa from the world of Mahouka felt quite inferior since he knew that he couldn't help much, yet what could he do? 

The magic in his world couldn't be used freely like in the world of DxD, and his physical ability wasn't that strong, to begin with. 

"No, no. You have helped me so much. If you aren't there, then my picture will be seen everywhere, and I will become the most vicious criminal on the next day." 

Yes, if there wasn't Masa from the world of Mahouka, Masa knew that it would be hard for him to hide his identity. 

Masa from the world of Mahouka might not be that powerful, but his attainments in bioelectricity-related magics, control over the minds, and technology-related knowledge were amazing, which greatly helped him to make his situation in the fight convenient. 

"That's great then..." 

Still, each Masa had their own role, and they helped each other become stronger. 

Masa, from the world of One Piece, tried to acquire a new ability and became stronger in his own ways. 

Masa, from the world of DxD, learned magic, strengthened his physical ability, and learned everything that was possible to be learned. 

Meanwhile, Masa, from the world of Mahouka, was probably the most complex as not only was he a magician, a scientist, a researcher, a doctor, and even a businessman. This guy learned everything that he could to improve his power and family, even if his ability was limited. 

Yes, the Isshiki Family might be a member of the 18 Assistant Houses, which meant Masa from the world of Mahouka was part of one of the strongest magician families in his country, yet even so, his family wasn't the strongest, and even on the weakest side, especially when it was compared to the other magician families, which was related to the 18 Assistant Houses. 

Heck, some of them were even weaker than other lower-ranking families. 

So, at this moment, while Masa from the world of One Piece wanted to take it easy and rest after his long fight with Kizaru, Masa from the Mahouka decided to take a turn to become the protagonist of the story, trying to strengthen himself and his family and if possible tried to protect himself and his family from the protagonist of the world Mahouka, who could destroy the world with a nuclear fission similar to the type of magic. 

Because of that, Masa from the world of Mahouka also said, "For the development of the Pika Pika no Mi, leave that to me." 

All Masa wanted was to become stronger, and they would support each other in doing that. 

---

There you go. 

By the way, I know that many of you wish for him to stay in the world of One Piece all the time, but tomorrow, Masa from Mahouka will appear; please look forward to it!
