Be stronger!

After returning to his domain, Masa took Asia to his room, letting her rest, then went to his laboratory to start his research about the Boosted Gear, which he had taken from Issei, especially when he had free time, considering he had to help Ravel when Ravel moved to his domain as she had become his fiancee. 

"Hmm..." 

As expected of the Longinus, Masa thought. After he got his hand on the Boosted Gear, he could tell that it was trying to rampage, trying to get away from him, like a wild beast that was impossible to tame. 

"It's different from Asia's Twilight Healing." 

After Asia became a member of his peerage, it was natural that he tried to research her Sacred Gear, Twilight Healing, and as expected, as he used his Supreme King Haki to dominate her Sacred Gear, it obediently followed him and let him use it. 

Meanwhile, the Boosted Gear was different. Even though he could use it, the soul within this special Sacred Gear known as Longinus tried to fight his control, yet he also felt that it was normal since the Welsh Dragon, Ddraig, which was the Heavenly Dragon, had rampaged over the Great War in the past, killing, destroying, and even tried to fight the god of the Christians despite a huge difference of power between them. 

"It's a good thing that this dragon is dead." 

One of the best things that god had done for humanity was to turn those creatures that harmed the world into Sacred Gear, becoming the power of the weak humans to fight against supernatural beings. 

Unfortunately, Masa wasn't a human, but he was a devil, so the weaker the human was, the better it was for him. 

"It'd be great if they caused trouble to other myths, though." 

After Masa took down Issei and took the Boosted Gear, he knew that his focus should be on something else, such as the devil itself and the other myths within this world. 

Yes, as a devil, his myth might be spread widely to the world, especially when he was part of the most widespread myth within this world, but it didn't mean that he was the most powerful, especially when in this world, many supernatural beings, whether it was gods, or even dragons had a power that was enough to destroy the world. 

However—

"So what?" 

In the original, all of them could only succumb to Issei, the perverted boy who spent all of his time on porn and masturbation. 

So, why should Masa be afraid of all of them? 

More importantly, he also had a unique ability, so he knew that he could grow even stronger. 

So, even if many problems in this world existed and might come to him after he had defeated Issei, so what? 

Masa didn't think that he would lose despite the fact that they had many unique abilities that could even affect the concept itself. 

Instead, they might as well fight each other so he could devour them, making himself stronger, and then also become the ruler of this world. His thoughts might be quite extreme, but then again, considering the nature of the gods in the myth, he felt like... it was better for him to be a devil to rule this world instead. 

"I think that all supernatural beings are the same." 

Yes, in his mind, Masa knew that all of those beings on the top were the same as humans. 

The only difference was their bodies; no, it should be their power. 

If a human had the power of a god, then would they be called a human anymore? 

By then, they would be called either a monster, a god, a devil, or even a hero. 

"What is it called again? Oh, right, Gnosticism."

Gnosticism claims that humans are but immature gods that can reach ascension and God's power with enough training, which even the Apostle John sees as blasphemous.

At the same time, while it sounded like blasphemy, Masa felt that gods were just like other species. Their existence was like that of a king, an emperor, a president, or whatever the name was before humans took control over the world. 

If there is a difference, it is in the shape of their powers. 

Regardless, he put the problem aside as he wondered what he should do with the Boosted Gear. As he had gained the DNA of the Welsh Dragon, Ddraig, he could create a replica or even the clones of Ddraig to become his monsters, letting them become part of his army in his domain, so if the Great War really happened, then there was a huge chance that a devil would win. 

Rather, the devils would mostly have the upper hand, especially due to their Evil Pieces technology, which allowed them to reincarnate powerful creatures from different races into devils. 

On the other hand, the church only had a pitiful number of angels and a group of fanatics. 

The fallen angel group was even more pitiful since their numbers were so low that they could only rely on the group of Sacred Gear users, who would probably betray them when a serious situation happened. 

Yet, this war would cause a huge weakness within the devil even if they ended up victorious, which made them become the targets of other myths, especially those whose myths were pushed away and had their believers taken away due to Christianity. 

Still, the war was good, so that way, he could erase all the tumors on the devil, so annoying devils, who thought their words should be listened to and followed, could go die. 

"Well, if they die, I will become them, too." 

As Masa thought so, he let loose his control over the Boosted Gear, and as expected, Ddraig started to talk. "You coward! You, a young devil, won't be able to control me! I am Ddraig, the Heavenly Dragon!" 

Being used like a tool by Masa so carelessly was a humiliating experience for a Ddraig, yet even so, it also had to admit that Masa was strong enough to take control over it after he stole it from its previous host, Issei Hyoudo. 

However, even if it had become a tool, Ddraig wasn't a weapon, a tool, or even a slave! 

It was its own being, and it wouldn't change even if it had died! 

"Just give up! You have no chance to fight me!"

As Ddraig kept talking, Masa opened his mouth wide, which made it confused. 

"What are you—"

Crack!

"GAAAAAAAA!!!!" 

Ddraig roared in pain as its soul was torn apart. 

Rather, not only Ddraig but all of the souls of the previous hosts of the Boosted Gear were screaming in pain as Masa took a bite of the Boosted Gear. 

Yes, Masa had gotten the DNA of the Boosted Gear, and all the rest was simple. 

As for what he would do with the Boosted Gear, it was definitely impossible to return it to Issei, especially given how perverted that guy was. 

Masa was also quite curious. 

If Issei lost the Boosted Gear, how would Rias and the others act toward him?

What would they do to Issei? 

Would the Gremory family follow their belief, who always treated their servants like their families?

Masa wanted to laugh at the duplicity of the Gremory family somehow. 

"It's good that I have engaged to Ravel." 

Compared to Rias, Ravel was simply an angel. 

Nevertheless, it was also for this reason that Masa couldn't give Issei a chance to rise up, so he decided to eat the Boosted Gear to empower himself. 

"Stop! Stop eating me! NOOOOO!!!" 

Unlike when Ddraig was killed by the god, with how powerful it was, it was impossible to die, and its soul would persistently live within the Boosted Gear. Its shape might be different, but the fact that it was still living didn't change. 

However, if Masa devoured Ddraig, then Ddraig would die completely without any chance of returning! 

All of its ambitions, dreams, and everything would end with this before it completely disappeared from this world! 

As Draig and all of its hosts screamed in horror as they pleaded with him, Masa finished eating the Boosted Gear. 

Burp! 

"Oops. If Aunt sees me, she will get angry." 

Masa closed his mouth with his palm, thinking that his way of eating was quite unnoble-like, but then again, he was glad that he had eaten the Baku Baku no Mi, especially when he gained the power of the Boosted Gear, all of its hosts, and Ddraig, which also, in turn, became the source of ability that made his foods could make the health of Mio became better. 

"Oh, how useful~!" 

At the same time, it seemed Ddraig was more useful than he had thought.
