Start by Eating Jake Jake no Mi

At the speed of light, it would take 0.13 seconds to go around the entire Earth. 

Unfortunately, while Masa had the speed of light, it didn't mean that he could travel at the speed of light to any place that he wished to, especially in those places that he hadn't been or wasn't sure which. 

Moving at the speed of light was difficult, and this was also the reason why Kizaru didn't go to the Saobody Archipelago from Marine Headquarters by using the power of Pika Pika no Mi. Instead, he went to the island by ship, and when he was close, he would use the power of Pika Pika no Mi to land on the island. 

The consumption of energy aside, it was relatively difficult to do long-distance and difficult maneuvers at light speed, especially since it was only the physical ability that could move at the speed of light, but the mind's speed couldn't catch up with the speed of a physical at all. 

Before the brain was able to comprehend everything, their physical being had already arrived, which made the Pika Pika no Mi difficult to control. 

To solve this problem, they either had to think about the speed of light or move without even using their minds. 

Masa's mind was comparable to a supercomputer, and naturally, it made it easier to move by using the speed of light, but what about Kizaru? 

Kizaru's mind couldn't move that fast, so all he could rely upon was his physical ability and reflexes, so he usually used the speed of light for short-distance travel and fighting instead of long-distance travel. 

Regardless, it was easy to see the difficulty of moving at the speed of light, right? 

Instead, moving at Mach speed was far easier for him, especially in a place that Masa hadn't been to, which was why he used his Fallen Angel form and used "Mercury," the new magic developed by Masa of Mahouka. 

While Masa couldn't use all of the magic mastered by Masa of Mahouka due to the lack of CAD, if it was a magic that relied on bioelectricity, then he could use all of them now, including "Coulomb's Sword" and "Dominator." 

Still, to defeat someone, he had many ways, so there was no need to hang up on the magic of the Masa of Mahouka. Instead, he should use his other abilities so that readers don't forget them, and all of his abilities wouldn't be so monotone. 

Nevertheless, he should focus on his goal, which was to get his Devil Fruit on the Impel Down along with devouring many powerful and legendary criminals. 

He might not be using the speed of light, but with his Mach 10 speed, it wouldn't take much time for them to arrive at Impel Down, but there was no doubt this would shock Carina, Perona, and Kalifa. 

"...Masa, are you a fallen angel?" 

"No, I just ate a fallen angel Devil Fruit before." 

"Oh!" 3x

Somehow, they thought that this might be a secret as to why Masa could eat several Devil Fruits at the same time. After all, there were many Devil Fruits in this world, and each of them had unique abilities. 

Still, was there a fallen angel in this world? 

Masa knew that it existed in the myth, especially when Buddha also existed, considering the Devil Fruit eaten by Sengoku, the Fleet Admiral of the Marines, was a Hito Hito no Mi, Model: Buddha.

'It's kind of weak.' 

Nevertheless, Masa felt that Sengoku's Buddha was relatively weak, which made him a bit strange, considering how powerful Buddha was in Masa of DxD. 

"...by the way, Masa, can you show your wings later tonight?" 

"...." 

Masa was silent, glancing at Perona, whose expression was like a janitor on a hentai story after she saw him having fallen angel wings. "...okay." 

Similar to him, who often asked them to dress as a secretary, nurse, maid, cheerleader, and many others, Masa didn't mind dressing himself up. 

At the same time, he thought of letting them eat the 2nd Devil Fruit. 

Masa, who had gained Teach's DNA inside his body, knew that it was impossible for him to modify the DNA of others so that they could also eat the 2nd Devil Fruit. 

'Is so, what kind of a Devil Fruit?' 

Out of all of them, he thought that it should be a Zoan type. 

Why did he think so? 

Not only would it increase their physical ability, but when Masa thought that they might have the ears and tails of a bunny, a cat, a fox, and many others! 

"..." 

Still, let's keep this plan a secret! 

"By the way, Masa, what is the Devil Fruit that you want to get so much that you are going to the Impel Down?" 

The three were clear on how much Masa wished to go to Impel Down, and they were clear that there was this one or several Devil Fruits that he wished to get no matter what. 

If so, what?

"Hey, instead of talking about what kind of Devil Fruit he is interested in, isn't it more important to ask about why he decided to become a king?" Kalifa looked at Carina and Perona strangely, who were more interested in what kind of Devil Fruit Masa was interested in than in his decision to become the Drum Kingdom. 

"Ah!" 2x

Carina and Perona only realized, and the two showed an awkward expression, but then, Masa was so easy to make his decision as if his decision to take the Drum Kingdom wasn't a big deal, so they couldn't help but forget about this matter when the truth this was a big deal! 

Yeah, being a king was a big deal! 

Yet, when they thought of Wapol, that greedy and large-mouthed man, and how easy it was for Masa to kill him, they felt that being a king also wasn't a big deal either. 

After all, in the end, a king was just a human like them, and when Masa killed them, then they were as good as dead. 

"Well, it's fine, isn't it? The Drum Kingdom isn't that bad." Carina felt that it wasn't a big deal to become a king of the Drum Kingdom. 

"Well, that's true." Kalifa nodded and said, "Moreover, this kingdom was just attacked by a pirate, and we could use this accident to make a story about him being the savior of the kingdom and the reason why the previous king died." 

"Genius!" 2x

As the three discussed Masa's new kingdom and supported his decision to become a king, Masa shook his head calmly, thinking that status and wealth were just momentary. It wasn't something that could be maintained forever. 

Only his own strength was the one that he could rely on. 

At least, in this world, if he wanted to maintain everything, then he had to be strong, or else the others would try to rob him and destroy everything. 

Still, Masa thought that the three of them were also affected by his influence as they started to write a story about how he could become a king righteously. 

At this moment, he was just a civilian, someone without status, but if a pirate could become a king, then why shouldn't he, right? 

However, let's talk about the kingdom later since—

"We have arrived." 

"Oh..." 3x

Watching the gigantic gate that stood in the middle of the sea, they felt slightly overwhelmed by the power of humanity as they were able to build such a massive structure in the middle of the sea. 

Still, their destination was a little further, and as expected soon, they saw a large fortress standing straight above the sea. 

Imposing and majestic, yet Masa didn't have much of an interest in observing this building. 

Slowing down, Carina, Perona, and Kalifa were slightly tense, but with Masa, they felt at ease somehow. 

"Carina." 

"Leave it to me." 

In front of the wall of the fortress, suddenly, a door appeared before them, and Masa entered the door before it closed automatically, returning to the previous wall and leaving no trace of their infiltration into the strongest prison in the world, Impel Down.
