Hiiro Masa. 

This was his name. 

Even though he had said that he was part of the Isshiki Family, the truth was that his father, who was the little brother of the head of the Isshiki Family, was adopted by the Hiiro family during childhood, so due to that, his family name was Hiiro. 

Still, unlike Tatsuya, who had an incomplete family and was treated like a tool by his family, Masa had a completely warm family, including a cute little sister. 

That was why Masa, from the world of Mahouka, felt a little awkward and felt that he needed to work even harder, especially when he thought of Masa from the world of One Piece, who met so many troubles after he was transmigrated to the world of One Piece. 

More importantly, while everything was peaceful, Masa knew that it was just the prelude of all the troubles, the calm before the storm. 

"Masa-niisama, hurry up and put on your clothes! Cover your body!" 

Still, his thoughts were interrupted when he heard the shy voice of his little sister. 

Hiiro Hiromi. 

Masa looked at his little sister, a cute girl with long brown hair, which she tied into a single braid reaching to her lower back. Her bangs are split evenly in the middle of her head, which reaches to her neck and frames her face.

At that moment, his little sister blushed furiously, watching his upper body, which was completely uncovered, showing his muscles, which had become even more perfect after he shared the physical abilities of Masa from One Piece and DxD. 

The shape, silhouette, and beauty of his body were simply godly. 

His body was probably like a real God of War, which brought fear yet intoxication to those who saw his body. 

Even Hiromi was completely in a daze when she saw her big brother's body.

Wasn't her big brother becoming more handsome lately? 

Not only his skin but his appearance, and everything became so much better that she wondered whether he had developed a new magic that could make his appearance better. 

Yes, Hiromi knew that her big brother was amazing, someone that she was proud of, yet because she knew that he was so exceptional, she was afraid that she would lose him, especially—

"Masa, are you here?" 

Suddenly, from behind Hiromi, another beautiful girl with long blonde hair and purple eyes also appeared. She seemed to be about the same age as Masa, older than Hiromi, and naturally, due to her similar age to Masa, she could appreciate his charm better.

Watching Masa, who was completely topless on his upper body, the girl fell into a daze and couldn't wake up until Hiromi's voice echoed from the training room. 

"Masa-niisama, hurry up and put on your clothes!" 

It was complete chaos. 

---

"What's wrong with Hiromi? Did you do something, Masa?" 

Masa's father looked at his daughter in doubt, and he could see Hiromi pouting, showing her annoyance toward his son. 

"Nothing is happening." Masa didn't care much about his body being seen by his cousin and little sister. After all, he was a man; why should he be afraid of his body being seen? 

Still, in this conservative world, there was no doubt that his action was seen as being shameless. 

Yes, unlike in the past, which is sometimes called an age of immorality, in today's age, everyone is conservative, whether in their type of clothing or their way in a relationship. 

In the past, many dressed openly, showing their skin, but now, everyone dresses in a way that covers most of their skin, and they also do sexual acts after they marry. 

Still, for Masa, in the beginning, this was a bit weird, but for him, who had lived for so long in this world and was also still young, he didn't care much about sexual acts, especially when there were many dangers in this world. 

A woman is nice and all, but getting stronger is a priority in this world. 

"Ah, uncle, aunty." 

Still, Masa was surprised to see his uncle and aunty, which caused him to look at his little sister, Hiromi, and cousin, Isshiki Airi. 

Yes, the beautiful blonde-haired girl, who was also a half-foreigner who also happened to be his cousin, was one of the heroines in the world of "Mahouka," Isshiki Airi. 

Unlike him, Airi was the daughter of the current head of the Isshiki Family, and naturally, his relationship with Airi was very close, especially when their home was quite close. 

Probably, their relationship was a so-called childhood sweetheart. 

Yet, Masa didn't think too much of it since they were cousins, and frankly, he was so popular that he was close with many girls. 

"Masa, is it me, or have you grown taller?" Masa's uncle, the head of the Isshiki Family, sighed in amazement when he looked at Masa, who had grown. 

Masa might be in his 3rd year of middle school, but his body was relatively massive as he was about 185 cm, and he would probably become even taller in the future. 

He was not as tall as Masa in One Piece and probably within the normal height of a foreigner, but in this country, there was no doubt that he was on the taller side. 

Moreover, his figure wasn't a bloated muscle but slimmer and compact, which was within the line of beauty and taste of everyone. 

"I am still in my growing period, after all." 

"I am a bit jealous, though." 

Watching his nephew, who had become more handsome and grown up, the head of the Isshiki Family sighed, feeling a bit jealous of his little brother, who had such an exceptional son. His two children were good, but that's it; they weren't exceptional, which was different from Masa. 

Yes, Masa was exceptional in the eyes of many, especially when he had helped the Isshiki family to grow in the field of cyber security. 

The Isshiki Family had been famous for their bio-electricity-related magic, but it was only Masa who thought of developing this bio-electricity for cyber security. 

Rather, when this family entered the cyber security field, all of them were like fish that had entered the water. Being able to manipulate bio-electricity gave them a huge advantage over cyber-related fields as they easily hacked practically any electronic device and bypassed typical electronic security measures.

Yes, due to Masa, all the Isshiki Family became experts in the cyber-field as the new magic he developed made them able to practically manipulate an electrical device. 

Due to this, their status among the magician family became even higher, and their position within the country became even more important as they were trusted with many secrets, considering their expertise. 

If one wanted to keep their secret or protect something, one should search for the Isshiki family. 

This probably had become an open secret among people with high status in this country, which gave their family wealth and influence within the country as governments, the military, businessmen, and many others often relied on their service. 

At the same time, if they wanted information, they also had to search for the Isshiki Family, yet this was a secret, and no one except for the family knew since if the world knew that they could get any information they wished through their hacking magics, they might be targeted. 

Still, when he looked at his daughter's expression toward Masa, he let out a helpless sigh inwardly. 

Yet, the head of the Isshiki Family didn't stop his daughter's feelings. Instead, he probably supported it since he knew well Masa's DNA was the best of the best, and at the same time, he also expected Masa to develop a new type of magic to make their family stronger. 

Moreover, Masa was the strongest magician in their family, and naturally, as a magician, it was normal to respect the strongest since the stronger he was, the better it was for the family. 

Or rather, as the masterpiece of the Isshiki Family, everyone respected Masa the most and expected him to lead their family. 

That was why there was no way he would let other magician families take advantage of him, and this thought was shared by every member of the Isshiki family, whether they were part of the main family, braches, or those who joined another family. 

Or rather, everyone imagined that he would be the one who would lead the magician in this country. 

Yes, only him. 

At this moment, when everyone looked at him, their eyes were filled with an obsession, thinking that he was the best of the best. 

"By the way, have you developed a new magic?" 

He asked this with a joking tone, but Masa said, "Yes, I did." 

"....." 

"Eh?"
