Start by Eating Jake Jake no Mi

Masa Vapula. 

Heir of the Vapula Clan. 

He was probably the strongest devil that had ever been born in this family, and he might even be stronger than his progenitor. 

However, the problem is that he is a Vapula! 

The devil whose innate ability was to tame or control a lion! 

Any lion creature in this universe, be it from reality or myth, once they crossed paths with him, their fate was sealed.

No matter how strong they were, they were under his control! 

Frankly, his talent was great, and due to the amount of his Demonic Energy, he was even better than his progenitor. 

To be honest, when he was named heir, no one objected, especially when he showed a strong talent in governing his territory and showed extreme talent in his innate ability of Vapula Clan. 

In terms of governing, the GDP of his territory had increased many times, and as he became the heir of this family, he also started to monopolize several industries in this world and underworld, especially pets, animal care, confectionery, spices, foods, retail, and media. 

What about other industries, such as technology and medicine? 

If possible, he wanted to enter since those industries made the most profit, but he knew well that even if he was quite "smart," there were many who were smarter than him, such as Ajuka Beelzebub, who was the creator of the "Evil Pieces," a set of 15 chess pieces given to High-class Devils to increase their ranks by reincarnating other beings into Devils. 

Naturally, he got the "Evil Pieces," too, but he hadn't used them since he didn't have much interest in them. 

But let's put that matter aside, and frankly, as he was young and the overall power of the Vapula Clan was just like that, he wasn't greedy and just maintained the status quo.

There was no doubt that his territory might not be the richest, but due to his management, it had become one of the top ten best territories in the Underworld. 

Nevertheless, similar to Masa in the world of "Masa," who couldn't show all of his power, Masa in the world of DxD didn't dare to show all of his ambition since, once again, there was a limitation within the innate ability of the Vapula Clan. 

Lion taming. 

This was the ability of the Vapula clan, and due to this, they had collected many mythical lions in the Underworld, whether it was Manticore, Griffin, or even Sphinx! 

He had collected all of them and let those creatures live in his territory so they could protect his territory and people! 

They might be ugly, but they were strong. 

"Yeah, I know that it is a hard truth, but they are too ugly." 

Whether it was Masa from the world of One Piece or Mahouka, the two had to agree that many lion-type mythical creatures were ugly.

Or rather, those lions were too creepy! 

Well, Griffin was cool, though. 

"...let's put appearance matters aside since what matters is strength, right?" 

"You are right." 2x

It didn't matter what their appearance was, but as long as they gained strength, they would gain respect. 

"By the way, can you merge with those creatures?"

"...if possible, then will I even stay low-key? If I am strong enough, then I will directly get Kuroka and Koneko, you know?" 

If this lion-taming ability could be used to strengthen himself, such as merging with the lion-like mythical creatures such as Griffin, Sphinx, Manticore, or even Nemea Lion, even if he couldn't reach the Top Ten strongest in the DxD universe, it was possible of him to enter the Top 20! 

Unfortunately, he couldn't, and the best he could do was to improve the lion-taming ability into a feline-taming ability, controlling all the types of feline-type creatures, so there was no doubt if he used this ability on Kuroka or Koneko, they would be an obedient domestic cat by his side instead of a naughty stray cat. 

Still, with his Demonic Power, he could strengthen those lion-type creatures and create a new powerful lion monster of gigantic size. 

It could be said that the power of his clan was quite similar to that of one of the four Satan families, Beelzebub.

However, unlike him, who manipulated a lion, Beelzebub's ability was to manipulate insects. 

Still, which was better, a lion or an insect? 

If he had to say, naturally, it was an insect since it was invisible, cheap, and also poisonous. 

Or rather, there was a record that one of the devils from this family could create a gigantic, powerful fly that brought death everywhere, and only the strongest devil in the current era, Sirzech Lucifer, could stop it. 

Then, if the insect could be so strong, then shouldn't the lion do the same? 

Once again, a lion or a feline-type creature was powerful, but it had a certain limitation. They might be called apex creatures, the king of the beasts, but all their advantages were their strength, speed, flexibility, or cunningness. 

What could a lion do when facing the overwhelming power of the dragon or deity? 

Still, if Masa really could merge or transform into those lion creatures like the Bune Clan that could transform into a dragon, it would be good since that way, his speed, regeneration, and power could increase, but unfortunately, he really couldn't.

"What about the Longinus? With your power, it shouldn't be difficult to gain Regulus Nemea, right?" 

Sacred Gear. 

This was an item created by the God of the Bible from the soul and body of a legendary creature.

Among the sacred gear, there were a few known as the strongest known as the Longinus, which made the user capable of even killing a god. 

This was also the origin power of the protagonist of the DxD universe, which made him slowly become the strongest being and achieve his dream of becoming a harem king. 

Still, they didn't care much about Issei Hyoudo, the original MC of this world; instead, they were more curious whether Masa from the world of DxD had gained a Longinus or not since they knew all of those Longinus, one was created from the body and soul of Nemean Lion, the legendary lion in the myth, and the strongest lion too, called the Regulus Nemea. 

If Masa could get the Regulus Nemea, it would even be possible for him to enter the Top 10 strongest! 

"...I am not the protagonist, and do you think it is easy to search for a Longinus?" 

Masa from the world of DxD felt speechless because of their words.

Since there are billions of humans in this world, how could he find a Longinus? 

He wasn't the main protagonist who was so lucky that he could become the one among the billions! 

Or rather, he should have used all of his luck to reincarnate as the most powerful and talented Vapula clan devil.

More importantly—

"More importantly, I don't have a good background or backer that can protect me from the danger that comes from gaining that power." 

"You are right." 2x

Once again, Masa from the world of One Piece and Mahouka had to agree. 

Background or backer. 

They knew that no matter how strong the potential of the protagonist in the story was, if they didn't have a good background or backer that could help them become stronger, it would be impossible for them to grow. 

How many talented people had died before their power bloomed? 

Many! 

It was also because Issei Hyoudo was the servant of Rias Gremory, the little sister of the strongest devil, Sirzech Lucifer, that he could grow. 

If Issei became the reincarnated devil of another devil, then it was impossible for his growth to be so smooth, as the others would definitely be jealous and try to kill him. 

Everything that Issei gained in the story was all due to Sirzech, so there was no doubt that Issei, who almost touched Grayfia, Sirzech's wife, was the lowest. 

Fortunately, Issei was a virgin and a coward, so nothing happened. 

However, if it was someone else, could they even stop themselves from touching such a beautiful wife who presented herself and gave her everything when her husband wasn't around? 

Masa definitely couldn't do it, and he would definitely make a move. 

Still, the real problem was that he didn't get the Regulus Nemea because he didn't have a strong background to protect himself and grow. 

In the original story, the Regulus Nemea, a Longinus created from the Nemean Lion, was mastered by Sairaorg Bael, the heir of the Bael Clan, who was also the Great King of the devil, and the house of the leader of the Great King Faction, so even if this family was pressured by the Four Great Satans faction, he could hold on. 

However, what about Masa?

Masa's family might be good in the eyes of the ordinary devil, and many would be envious of him, but in front of the strongest, it wasn't enough! 

In the world of the DxD, being a genius wasn't enough, and what one needed to become was either a pervert or a monster! 

Masa was neither of them, and his limit was probably the "Ultimate-Class Devil," but by then, it was impossible for him to grow stronger anymore, so he knew that the best way for him to live in this world was to be low-key. 

Yes, he might not go after those main heroines, but even so, there were still many beautiful women that he could go after, such as Issei's mother, Rias' mom, Sairaorg's mom, and even Riser's mom! 

At the same time, he also thought that it might be a good chance for him to start to use his "Evil Pieces" since he hadn't used them since he had gained them. 

"But you don't have to worry. I have a good relationship with Sairorg-nii." 

"Sairaorg-nii? Are you younger?" 

"I should be one year younger than the protagonist."

"So, the same year as Koneko?" 

"Yup." 

"By the way, has the story started in your place?" 

"Hmm... it should happen soon since Rias and Sona should be in the third grade, and Riser-nii told me that he wanted to meet Rias." 

"...you have a good relationship with Riser?" 

Riser Phenex.

Riser was the first villain who was defeated by Issei, yet Masa told them that he had a close relationship with Riser.

"It's normal, isn't it? We're coming from a noble family, after all, and I am also the heir, so I have to have a good relationship with other devil houses. More importantly, the number of noble devils is low, so it is more than a reason to have a good relationship with each other, especially for us, who don't have a powerful family who can protect us, like Sona and Rias, who can go to the human world as they wish." 

When Masa from the world of DxD finished his words, the two looked at him and said, "I think that you just want to get close to Riser's mother and little sister, right?" 

"..." Masa DxD. 

The two nodded and thought that Masa from the world of DxD was still the same. 

"Be careful." 2x

Still, the two looked at Masa with concern since if Masa from the world of DxD was close to Ravel Phenex, the little sister of Riser Phenex, then... when Riser lost to Issei like in the original story... 

Masa from the world of DxD took a deep breath and nodded. "I know, you don't have to worry. I might not be able to become the strongest, but I am not weak, and if someone picks up a fight with me, even if it's Satan, I will kill him even if I have to die." 

Frankly, he couldn't care less about Rias or Sona, but as the two had said before, he was close to Ravel, and if Issei's victory over Riser would bring a certain reaction, then he knew well that he had to take this matter into his own hands even if he had to offend Sirzech Gremory. 

Still, at this moment, the three Masas realized that everyone had their own difficulty, and to solve this difficulty, they had to work together. 

"By the way, you should try to search for a Devil Fruit." 

"I agree. If possible, try to get Paramecia since it has the most potential." 

"I think he should eat the "Goro Goro no Mi," so he can become a human thunder!" 

"That's not bad." 

If Masa from the world of One Piece could eat the "Goro Goro no Mi," then there was no doubt that the three of them would become even stronger! 

"Wait, what was your timeline?" 

Masa from the world of One Piece felt a little helpless, but he decided to be truthful since he knew sooner or later everyone would find out. "I am not sure what timeline I am in now, but... probably like you guys, I should be within the canon time, or just a moment before the start of the adventure of Luffy, but to be honest, I have eaten a Devil Fruit, so I can't eat the "Goro Goro no Mi" even if I want to." 

"You have eaten a Devil Fruit?!" 2x

"...yes." 

"As expected, you are us." 

"Yeah, if you are not lucky, then you are not us." 

Their luck might not be as outrageous as the original protagonist, but the fact that Masa from the world of One Piece could get a Devil Fruit after he just arrived in the world of One Piece showed that he was like the two; his luck wasn't bad. 

More importantly, as there were the three of them, their luck would also be combined together, which gave them greater luck! 

"What kind of a Devil Fruit did you eat?" 

Still, what kind of Devil Fruit did Masa eat? 

Even if it was a normal Zoan Type of Devil Fruit, which was known as the weakest Zoan and lowest potential Devil Fruit, it didn't matter since they believed that they could make it stronger. 

However, his answer made them not know how to react. 

"...it's Jake Jake no Mi." 

"...what?" 2x

"It's Jake Jake no Mi, okay?" Masa from the world of One Piece let out a helpless sigh and said, "I have become a human jacket." 

"..." 2x
