Dancing Circles on the Horizon of Events

"In what way are you trying to enchant (...) and do (...)?

"Hey...... Do you know what an alfania is?

…… Shin? "

"Photos. You don't seem to know how it is... (Well, what is it...)"

Waltz, who found out that Alfania didn't know the pictures, worried about whether to tell her what the pictures were. He expressed concern to the rumored Alfania that she was still alive in future times that poorly taught technology would change history. Having done so many things so far, the world of the future has not changed, so there should be no problem teaching Alfania the principles of photography... As for Waltz, whose weird thing is the cautious one, he didn't seem to be worried.

She seems to have decided to explain her conclusions only, largely omitting descriptions of the components in making cameras, such as troubled citations, lenses and focal points, and silver salt films.

"Look, like this, twisting the light brings up the view you see"

With that said, Waltz unfolds about three gravitational lenses to form the scenery on the side of the Enchant's instrument. As a result, Alfania, without knowing the translation--,

"............" Pocahontas

--seemed to have opened his mouth when he saw the view he had formed with. But still, Waltz's explanation doesn't stop. I was going to finish my explanation before I got weird here.

"So when you change the bending of the light, you can make the statue smaller or bigger like this. This is the principle of photography, and what we're going to do is we're going to form a magic circuit on the subject's surface like this, and we're going to draw a magic circuit on the subject's surface."

Having heard such a proper explanation of Waltz, Alfania, when it comes to --,

"... right!" Gattang

—— He understood something and rose to momentum.

"Er... sorry, Alfania. Which part, yeah! Why?

"I mean, is this the same principle as the eyes of people and demons?

"What... (No way, now you know?!

"I never had the idea of using my eyes as a tool. I see..."

"Wait a minute, Alfania. Let me tell you something, this isn't going out, is it? I don't mind doing a lot of stuff at Alfania's, but you can't let me out there, okay? After others develop it, I don't mind if you let me out..."

"I understand. Originally, I give up or sell the work I made to someone, etc. --"

""... things, etc?

"... whoa hon. I can't say anything about what Lord Waltz taught me. Don't worry."

"Oh yeah... (I'm not relieved...)"

"(Sister, you stepped on a mine quickly ~)"

"So, yeah. Using the principle of the eye, I knew I could do a statue. But how do you draw a circuit using a statue? You can't just make a statue, can you?

There is no magic flowing in the circuit made of pictures, and it is not possible to transfer magic ink... Alfania couldn't think of a way to achieve what the Waltz called an enchantment.

Waltz, on the other hand, took two bottles from a work bench that was nearby and showed each to Alfania, while beginning the following explanation. Well, it seemed closer to the question than an explanation.

"Come on, Alfania? Here are two drugs. One softens when the light shines, and drug A remains stiff if it does not. And the other is Agent B, which removes only the soft part of Agent A. With this I can do something like magic..."

Hearing that word of Waltz, Alfania makes her eyes shine.

"Right! First of all... after applying the ink all over the subject, apply the drug A from the top and reflect the circuit... the part of the circuit where the light is shining should be soft, so use the drug B to peel it off, right? Then, only the unnecessary part of the circuit will peel off the drug A, so if you wash it with a mana or something, the magic ink will peel off... only the circuit will remain."

"That sort of thing. Is this some kind of etching technique?

"That's Lord Waltz. I didn't know it was easy to come up with dirty techniques like this..."

"No... I developed it, not me. And I'm not dirty..."

Waltz accidentally laughed bitterly before Alfania turned her gaze excitedly to the bottle she held. Apparently Waltz himself had similar feelings for those who invented the art of etching to those of today's Alfania.

Then Waltz tries to demonstrate etching using the equipment provided... In doing so, she realizes that the experiment is flawed.

"... ah. Right. Alfania? Magic ink, you got it?

"Magic ink? There's no way I can keep it. Isn't Lord Waltz keeping it?

…………

And the air on the spot that solidifies. Apparently, the three of them were oblivious to the preparation of the most important.
