The sphere fell from high in the heavens - it was deploying a barrier - and Tesfia caught it without danger.
　As he pressed a few buttons while looking at the surface of the sphere, the driving sound stopped and the light indicating activation disappeared from inside.

'You've made something interesting in a little while I haven't seen it,'

　This was the moment when Ars's curiosity as a researcher had raised its head.

　It was unusually Tesfia who responded. I'm not going to be able to get the same kind of information from you.

'This?　Kohon.........well, it's called the Duel Sphere........
So?

　He urged her to continue, but Tesfia shifted her gaze in the direction of the day after tomorrow, and her mouth moved to say something, but she didn't say a word. It seemed that she had done something unfamiliar, and what she had heard had fallen into the pit of her memory.

'Al, I wonder how you're doing with the energy needed for the barrier.

　Loki, who suddenly throws such a question at you, must have been anticipating what would happen next. It's a good idea to be able to have a good time with them.

　And as if invited by Loki's palm, Ars began to ponder, "Hmm.

'Probably due to pseudo-magic power. The substitution system itself is a machine and a pseudo-magic system, as is the one in the academy's training grounds. It's a good thing that the machines and special techniques complement a different configuration than magic in the first place, so pseudo-magic power is enough to deploy it. If you don't know, the barriers in the training grounds are inexpensive in terms of cost, but the amount of pseudo-magic power required is commensurate.
So that's what happened.

　Rather than the question being answered, this atmosphere, this exchange, reminded Loki of his days at the academy. Therefore, Ars hesitated for a moment on the second phrase at the discrepancy-like situation of responding with a carefree smile.

''Yeah, yeah, that's it!

　Tesfia points at me as if she'd said exactly what she wanted to say in a flash. This is exactly the moment when the itch is reached.

'How come I, seeing it for the first time, know more about it than you do? Anyway, the fact that it fits........
Yeah, apparently it's all thanks to the protective pseudo-wall that Al put in place in each country.

　Before Tesfia could open her mouth, and even more so, it was Alice who took over the words that Ars tried to continue. She glanced at her best friend and flew a wink with a mischievous look on her face, "Switch".

　However, from Ars's point of view, Alice's statement was something she hadn't expected to hear. The fact that Ars produced it has been treated as a secret in each country. Ostensibly, it feels like the plot that the seven countries are jointly setting up the installation and that the association is biting the bullet on this national project is a blank slate.

　Seeing Ars's twitching expression, Alice hurriedly waved her hands in the air.

'No, no. I didn't tell anyone, I swear. Even the chairman has told me so.''
Mr. Chairman...?
''Yes, Chairman Ilyce. The 《Duel Sphere》 is also on loan from the Association, and I've received a full explanation about the 《Duel Sphere》, so I'm completely receptive to it.......

　Alice mixed self-mockery as she scratched her cheeks and thought she was explaining something great. But the reality is that the red-haired girl who must have received the explanation has completely forgotten about it. Ars's assessment of Tesfia's taller stature was temporarily put on hold.

''Ilyce, or was it true that as you get older, your mouth gets lighter?''

　Wanting to talk to the young ones, is a scene that was also seen in the outer world base [Wictor].
　The two "ages? Before the question of "what's going on?" tails off, Ars tries to turn the tables on the gaffe. He seems to be concerned about it, and this is also something that cannot be made public. The name Ilyce was chosen so that she could not only make up her mind, but start again.

'As far as the situation is concerned, I understand, mostly the mission is also something that involves Ilyce.

　He answered immediately, "Of course.

I've heard that there's an unprecedented rush of development, with researchers from all over the world pouring over the material on the creation process. I've heard that it's more energy efficient than existing ones, and that it's a theory that's been shortened by a few years in the field of magic.

　After receiving repeated requests from the many national researchers involved in the creation of [The Third Babel], Ars also decided to disclose the information. Since only the heads of states had the authority to disclose the items related to the protective wall, they were unable to do so, but they only disclosed the information regarding its operational efficiency and other aspects of fuel efficiency.

　As a result, small and portable barriers like the Duel Sphere were probably developed as a result. Although pseudo-magic power was versatile, there was no balance between supply and demand in its consumption. Although pseudo-magic has often demonstrated its true value in infrastructure development, there was a limit to the amount of pseudo-magic it could produce.

　As a result, the supply of most of them was insufficient for consumption. However, the amount of consumption was reduced to less than half by the theory devised by Ars. Of course, in addition to consumption, this is an idea that focuses on the nature of pseudo-magic power, and the generation of much higher quality pseudo-magic power has been fundamentally rethought.

　The technology for storing the pseudo-magic power in a separate tank had also been greatly improved.
　In other words, even if the amount of pseudo-magic power produced is small, the effect of the pseudo-magic power is similar to that of pure magic.

　Ars held the lesson of the past that rapid development was not always a good thing. Nevertheless, it would be impossible to develop anything just by fearing it.
　Maybe this was a good thing if he thought it was also playing a part in Rusalka's rapid recovery.

''So, so........''

　It's not just the fact that they've been able to get their hands on a lot more than just a few of these things, but also the fact that they've been able to get their hands on a lot more than just a few of the things that they've been able to get their hands on, and also the fact that they've been able to get their hands on a lot more than just a few of the things that they've been able to get their hands on.
　You may be like a child, but you can't blame them for being childish, as you can see from the way they frolic.

　It's not just about the 《Duel Sphere》. Right now, the desire to show off those acquired knowledge may be leading the way, but the extra emotions may be clouded.
　Even so, you can sense a joyful look on her face.

''Al, what is it........''
Well it's getting a little noisy, isn't it?

　Following Loki's voice, Ars noticed, although they weren't yet far from the city, the sudden hustle and bustle gradually shook his eardrums.
　If that was the cause, Tesfia explained, pointing to a section of the "Duel Sphere".

''There's a camera mounted here, and it's able to relay a live feed, but........''
'Wait a minute!　You guys, how did you capture our location? Who leaked it?
It's...

　And once Tesfia and Alice looked at each other to see if they could say it, the decision was quickly made.

''Master Lithia, Head of Lusarka?''

　The slightest question mark was probably because he was afraid to mention that name.

　-- I see. He was fed a drink.

　This was obviously a consideration for Lithia. Ars himself may not have cared, but it would be difficult to get that reputation back again, even for someone who had been cleared of charges.
　At least Lithia did not tell Ars this time and broadcast the entire mock battle to the rest of the country so that his own people would not be prejudiced.

　Battles between magicians are familiar to the Seven Nations Goodwill Magic Convention and easily attract the public's attention. Even if this didn't remove all of the suspicion and fear once it was planted, it would have been a good opportunity to ease it.
　Of course, it might also have given people a break from the reconstruction work.

　But I'm sure they weren't thinking about what would happen afterwards.

　It is so popular that it can be said that there is hardly anyone within the seven countries who is not enthusiastic about magical warfare. Because it is the power that protects people as the embodiment of a dream or as a proud sword of study - magic.

　The clamor that grows noisier and noisier gradually brings even an earth shaking.

　The girls, except for Ars, loosened their cheeks happily and pulled Ars's hand.

''Come on, let's go.''

　Tesfia is the first to take Ars's hand, and on the other side, Loki shyly scoops his hand up from underneath and grabs it to counter it.
　Behind her, Alice happily pushes her back, "Run!

　It's as if there's no way she can get any speed.
　I don't even know if they really think they can escape. Even so, Ars's legs start to move as they are pushed and pulled.

"Wait, where do you guys think you're going?
Of course it's the institute.
