The magic in this world is very troublesome...

After Sumire came out from the bathroom, she was looking at Haru, who was still researching on his hologram computer that was given by Tabane. "Is this the reason why we stopped at Tabane's world before?"

Haru turned his head and raised his eyebrow when he saw Sumire was wearing a loose bathrobe and a towel on the top of her head. He saw her smooth legs, and her wet messy purple hair somehow made her more seductive. He quickly looked away and said, "No, Tabane has a lot of hacking devices and various tools, especially with her new power. It can enhance the functions and abilities of those devices and tools."

"I see." Sumire then sat next to Haru directly, ignoring the distance between them, or rather, she stuck into him. "So what have you found out? Is there something that I need to know?"

"Well, there are a lot of things, but the first thing that I'll explain is what a magician is," Haru said, but somehow when there was someone beside him, he felt relief. After all, it was tough and lonely to do the quest by himself. He missed the time he spent doing the quests with Esdeath, Jeanne, and everyone else, which was why he felt grateful that someone he knew was right beside him, after all, when he was alone, there were no people that he could trust, and even though he didn't say it, he was tired.

So just having Sumire next to him, Haru felt relief.

With all of that, Haru started to explain what a magician was to Sumire next to him.

A Magic Technician or Magician is an individual imparted with magic. Magicians can manipulate Psions which makes it possible to alter the Eidos. In the past, called "Supernatural Power Users," the name changed once magic became a technical skill, thus making them "Magic Technicians."

It is said that only 1 in 1000 teenagers have magical talent, which becomes 1 in 10000 adults after taking into consideration the loss of power due to stress during the growth process. However, this is only counting those with practical level magic. Those with combat-level magic are undoubtedly rarer.

"Wait, wait, what are Psions? What is Eidos? And how is magic in this world different?" Sumire asked since there were many things that she couldn't understand, but one thing for sure, she knew that a magician was very rare. After all, the chance was only 1 among 1000, and even those 1 among 1000 might not have an ability to fight, which made her realize how rare a magician was.

"Well, from what I know, there are two kinds of magic, which are ancient magic and modern magic. I won't explain ancient magic since it is quite similar to the magic you see in a novel or storybook-like using an amulet, talismans, etc. On the other hand, modern magic is a skill that changes real-world "phenomena." Haru looked around and said, "For example, this building, this room, is the condition of "now." There's information in every "phenomenon." This world "information that is attached to phenomena" is called "Eidos." Magicians do not create anything with magic spells. "Eidos" is manipulated by temporarily rewriting information."

Haru then tried to use magic in this world. Even though he didn't need to be so troublesome since he could use it immediately, he wanted to test whether he could use magic by following how the magician in this world used it. "For example, if I want to create heat with magic, it doesn't mean that Psion will instantly make it for me, oh, by the way, a Psion is like a Mana, Chi, a Magic Power, or something."

"Then how do you make a heat if not by transforming the Psion into a heat?" Sumire asked.

"Well, the heat is created by accelerating the molecules in the air, and I have to admit that the process of using magic in this world is very troublesome," Haru said, and he could feel the heat on his palm.

Sumire also could feel the heat, even though it wasn't that strong, but she could feel it. "How did you use it?"

"The first thing we need to do is chant the spell, in this world, or rather in this modern world, they don't call it a magic spell, but rather, a "Magic Sequence," then to fasten the process of magic, they also need a catalyst, if usually, the magician will use a wand or book to use their magic, then the magician in this world will use a CAD."

"CAD?"

"Yes." Haru nodded and said, "CAD is a "Casting Assistant Device." It's a device that helps magicians to use their magic."

"Do you have it?" Sumire asked since she wanted to see it.

"Here." Haru took out the CAD that he had taken from the yakuza group before, and after he rewrote everything inside, he didn't need to worry that someone might be able to track him.

"It has the shape of a bracelet?" Sumire raised her eyebrows.

"There are a lot of shapes. Everything depends on the company, users, etc., it can be anything, as long as it helps the magician use their magic," Haru said. Even though the CAD might be useful, that was all, as long as the magician was powerful enough, or rather, very powerful, they could use magic directly without using CAD. However, he knew that even with all of that, it was still necessary to use a "Magic Sequence" or a Magic Spell since it was the setting in this world.

"Well, let me continue my explanation."

"Um."

"After the CAD process, it will send back that data to the user. Then the magician will be projected out into the real world. Of course, only some magicians can do this since most of the magicians don't have a fighting ability and decide to enter an engineering profession," Haru said.

"It's so complicated, unlike the Fairy Tail, or the world where you previously go, in all of those worlds, you only need to use your imagination, then the magic will be constructed, but in this world, it feels like programming on the computer? Is that right?" Sumire asked.

"Yeah, it is like programming. You need to create a set of instructions that tell the Psions in this world to move before it is projected into this world," Haru said. He was sure that if Shin was sent to this world, that guy would become an ordinary guy without a doubt. After all, to use magic, they needed to create a set of instructions before it was projected into this world.

"Still, all I can say about modern magic is like a molecule or atom manipulation, right?" Sumire said.

"You're not wrong, it is a molecular manipulation, but still, it is a powerful ability, right? You can manipulate a molecule after all," Haru said.

"That's true, but I wonder whether I can learn it. It seems to be very difficult." Sumire then rested her head on Haru's shoulder.

"With me here, you don't need to worry. I'll learn it with you," Haru said without hesitation.

"So what is our plan after this? How are we going to do this quest?" Sumire asked since it was the most important question that she really wasn't sure what they needed to do in this situation. After all, she was only a smart scientist and doctor, and she didn't have a talent in politics, leadership, and manipulating people.

"Well, in truth, I have been thinking a lot of ways, but before that, let me show you something amazing," Haru said and showed something to Sumire.

"Oh? What is it?" Sumire asked curiously.

"Hlioskjalf." Haru smiled and thought that there were really many good things in this world, especially this spy network.
