Everyone has their own troubles 1

Nerve Disturbance and Lightning. 

Those were the two trademark magics of the Isshiki Family, and as the most talented magician born within the family, there was no doubt that Masa's life was quite easy, and everything that he wished to learn and wanted was mostly granted. 

After all, the stronger Masa was, the better for the family. 

However, even if he was talented, he was still within the limit of tolerance, and even if he was known as the strongest in the family, compared to Tatsuya, who could erase anything and recreate anything, his existence was nothing. 

Yet, there was doubt: Masa's two strongest magic were useful, especially when it was innate, which meant that he didn't need to use CAD, a Casting Assistant Device, a spell support processor similar to a wand, staff, or something alike, but in the world of "Mahouka," to cast those two spells, so whether it was Masa from the world of One Piece or DxD, the two could use them with ease. 

Naturally, he still needed the CAD if it was another magic, but if it was two trademark magics of the Isshiki, there was no need for him to do so. 

Still, let's explain Masa's two trademark magic of the Isshiki Family. 

First, "Nerve Disturbance," the official name being "Nerve Electrical Current Disturbance" or "Nerve Impulse Jamming," is a short-range magic that can directly interfere with the nervous system of living beings. When used, it interferes with the enemy's nervous system, paralyzing their five senses and voluntary control. 

There was no doubt that it was a powerful magic, and even the magicians from the Isshiki Family, many of whom had no aptitude for this ability, so there was no doubt that he could use this magic without even using CAD, as naturally as he was breathing, was the best of the best. 

Still, while this magic is powerful, it also has limitations, as the bio-electric current interference magic of the Isshiki Family to work reliably has to be used within a distance of several meters of the target. If the target were to act as a friend and then betray the user, then this magic would be meaningless as using it at a close distance will cause the magic to fail, and at the same time, the magic can't be used from a far distance, and its limit distance is just a few meters.

It can't be used at a close distance or too far away, which makes this magic appear meaningless, yet it is okay since the main use of this magic is to capture enemy Magicians alive. 

Still, considering how this magic would directly affect the human body, there might be a question as to why this magic wasn't taboo or banned, and to answer that question, it was because this magic did not cause direct interference to turn the body into a puppet.

Well, as long as magic doesn't have the ability to turn a body into a puppet, everything is okay. 

Still, in his hand, this magic was dangerous since if he wished to do it, he could develop it further to manipulate the minds of people by sending bio-electricity to their nervous system and brain. 

Yet once again, if he really did, it was impossible for him to live anymore as he would be seen as a criminal, and many would be wary of him since no one wanted to be controlled, so he really hadn't shown this to anyone, especially when he knew how the treatment of a strong magician wasn't as glorious as it seemed. 

Moreover, frankly, due to his mastery over this magic, he had been living worrying whether he and his family would be killed since, unlike Tatsuya, he didn't have the ability to erase this world completely, which made no one dare anger him completely. 

Still, even so, he often used this magic, considering the convenience and the expectation of the family. After all, unlike his family, he didn't have a limited distance, and he could use this magic as long as he saw his target, but naturally, he made himself appear weak as if there was a limit within him since if this fact was known, there was no doubt that everyone would see him differently since once again, his family wasn't strong enough to bear the consequences of having a strong magician and he wasn't strong enough to protect his family. 

He might be a magician, but his body was just slightly stronger, and in case he faced the modern types of a weapon such as a Gatling gun, railgun, or even a nuclear bomb, he knew that he was as good as gone. More importantly, while he knew that he was powerful, there were still many ways for him to be killed since he wasn't invincible. 

Lastly, he had made many connections with many important people in his life in this world, so if possible, he didn't want to live as usual without having harm due to the consequences that came from being known as the most powerful. 

So, even if he was strong, he hardly used his everything, especially when it was related to this magic; instead, what made him famous in the family was that there was no doubt about his second magic, Lightning. 

While the name of this magic is "Lightning," it isn't magic that makes him release an electric, lightning, or even thunder. Instead, it is a spell that uses magic to perceive information that can be recognized and directly used without intervention from the brain and nervous system in order to move the body and spirit directly.

Lightning creates a shortcut in the process of transmitting electrical signals to the brain; this creates perception speeds capable of handling magical acceleration, which under normal circumstances is one more step where perception is established by transmitting the information to the brain.

It is a neurotransmission process shortcutting magic, but the Isshiki Family uses the magic's name, "Lightning," as camouflage since its true nature is not speed but quickness that puts them ahead of their opponent.

Well, in simple terms, this magic allows the user to have an instant reaction. 

When one was thinking of making a move to cast magic, a magician from this family had already made their move and killed the other. 

With this magic, whether it was close-range or long-range magic, no one could match him since they would be taken down by him first before they could even do anything. 

"Wow..." 2x

Yet, there was no doubt that the master of those two magics from the world of Mahouka made the two Masa feel happy since they knew that with those two magics, they would become stronger! 

"So, the focus of the Isshiki Family specializes in magic interference of electricity in living organisms, right?" 

"That's right." Masa from the world of Mahouka nodded. "Due to that, I have been studying medicine, trying to develop a new magic for my family, and all related bio-electricity-related research, so try to learn medicine there, okay?" 

He had been focusing on learning medicine, and there was no doubt the knowledge of medicine from the world of One Piece and DxD made him drool. More importantly, as long as he could improve the influence of the Isshiki Family on the world of medicine, his family would be stronger and safer; after all, in this world, who didn't want to be healthy? 

Who wanted to die? 

By then, no one would think to harm his family since if they didn't want to die, then they had to curry favor with him and his family, right? 

At the same time, gaining this new ability, the ambition that he kept inwardly started to set ablaze, roaring as he was ready to make his own power. 

"You don't have to worry." 

"Leave that to me." 

Masa from the world of One Piece and DxD nodded and agreed that to live well, one needs to take care of one's health, so it was natural to learn medicine, right? 

Still, there was no doubt that the power that was brought by Masa from the world of Mahouka was great since his family had a mastery over bio-electricity-related magic, and electricity had been one of the most powerful forces in the world, which was a great thing! 

"By the way, what is your timeline?" 

"Are you in high school? Have you met the protagonist?" 

"No, I am still in my third year of middle school, and I am about to start my entrance examination, so there should be a time before the start of the story, considering my cousin Isshiki Airi and Ichijou Masaki, the protagonist's rival, is the same age as me."

"Then, have you chosen which high school you intend to go to?" 

"Probably the Third High School, where the Magician of the One usually studies, but, you know, I think there is more fun if we go to a certain option, right?" 

The three Masas looked at each other and had a knowing smile. 

The three of them might appear kind, but it was because they were weak.

But once they gained power? 

There was no need to hesitate anymore!

"By the way, what about you? Which devil family are you from?" 

Masa from the world of Mahouka quickly put his attention to Masa from the world of DxD. 

Unlike Masa from the world of One Piece, who had just started his journey and even died, Masa from the world of DxD had a similar background to Masa from the world of Mahouka, who had a good family, so there was no doubt that he should be strong and had something that could be shared immediately with everyone. 

More importantly, as Masa from the world of DxD came from a devil family, he should have an innate ability, like Masa from the world of Mahouka. 

However, where did Masa from DxD come from? 

Gremory? Sitri? Or a non-canon family? 

If possible, the two wished for Masa from the world of DxD to have an electricity-based ability since, if so, then they could become even stronger as Masa from the world of Mahouka had two such powerful bio-electricity-related magic. 

If Masa from the world of DxD had electricity based on ability, their strength would definitely improve faster! 

However, Masa from the world of DxD became awkward since he also understood their expectations. 

"No, I am not from a non-canon family, and unfortunately, I don't have electricity-related abilities." 

"Then...?" 2x

Which family did you come from? 

"Vapula." 

Masa looked at the two and said helplessly, "I am from the Vapula family." 

"..." 2x

By the way, someone asked how many chapters I would update for this story, and I answered that I would have either one or two chapters daily, depending on the length of the chapters.

As for how much Masa it will be, I will make four Masa, and depending on the story, I will add more. 

By the way, just ask, which world do you want the fourth Masa to come from?
