A week later.

Once again, a birthday party was held at the Misaka Design Bureau to become the "Misaka Yayoi Birthday Festival".

Based on the last reflection, SS and Toto Design Bureau officials seem to have stopped making it a lame, lavish event.

It should also be noted that the staff was responsible for the dry food last week. It was delicious.

More than that.

"I'm late, but happy birthday, Mr. Yayoi"

"Oh, thanks...... And clothes... thanks"

I'm not used to wearing it, it's cute that Mr. Yayoi brings it to his freshly tailored clothes.

The clothes changed mainly the structure of the jaws and underwear due to the two tails. But the basic design goes hand in hand.

Because of this, I thought it would be better to change the design, but the tailor was unfamiliar with the Japanese-style costumes Yayoi often wears.

I don't know, I don't know if it would be nice to have a clothes-style yayoi, but then I think Yayoi would reject me.

Anyway, I'm glad that Yayoi is old and growing up safely... yeah, I'm glad to hear that. It's good for a child to grow up.

"Dear Akira, why do you have such a depressing look on such occasions?

"Nandemonaides"

While Sophia reads her mind a little, the birthday party progresses unconnectively.

There is no booze, by the way. It's because the bureaucrats don't run wild, and there are some educational problems with Mr. Yayoi.

"Hey, come on"

"Alcohol starts when you're twenty."

"There's no such thing as a decision."

Don't let Lori drink. I need Mr. Yayoi to grow up healthy.

"So what caused you to end up with more tails?

"Oh, that's according to old literature..."

And, Mr. Sophia just explained, there was a zucchin 'interruption from the side.

It is Leona Calzette with four tails growing on her head.

"Because pure fox tribes are highly magical and demonic!

…………

And Mr. Sophia, who was deprived of the dialogue, became a muddled expression,

"Why did you bring me here?"

And he whispered in my ear.

It sounds like Leona would whisper because the distance is close, but you probably know what you're doing.

Really, these two are close, aren't they? I smile when I look at it.

"Where did you get the information about the birthday?"

"It's weirder not to call this genius, Master Leona! Even I can celebrate Yayoi's birthday!

No, I'm sure Leona and Mr. Yayoi aren't friends you don't know, but they're ostensibly the top tech side of the Demon King's Army Development Authority and the top tech side of the Missaca Design Authority.

Normally, I wouldn't send invitations on alert.

But Leona came to herself unintentionally through it. If you try it on Mr. Yayoi, he's an admirer, and I hope so because he was welcoming you.

"So, what is it? You get more tails when you have more magic?

"Yeah, yeah, yeah. When magic increases, so does magic power. And when you use powerful magic, magic waste heat really develops in your body. I think the waste heat treatment system is the tail in the case of the Fox. So, that the weak-minded Fox tribe has no reason to have their tails in two. So I'm assuming you have one tail but Yayoi!

"'I think' or 'guess'...... What do you say, Mr. Sophia? You hit it?

It would be written in old literature, and I shook the subject thinking,

"Come on......"

and was returned. You know, I thought I'd tilt my neck.

"You didn't write that much in the literature. There was just a statement saying that if you have more magic, you have more tail."

"... I see"

Should I say boulder that I can deduce Mr. Yayoi's tail growth phenomenon from less information?

"You thought it was really interesting. Because the magic waste heat treatment system does it with trial and error, even my demon statue. If you dissected Yayoi's body and analyzed the system, it would be useful for my research..."

"Hih."

"Don't worry, Yayoi. It only hurts the first time - it hurts!

"Hey, Leona, that's all I'm threatening you with."

Mr. Yayoi freaked out too much to grab my arm and let go.

"Just kidding, kidding"

"It doesn't sound like a joke when Leona says..."

When I open the mysterious door of the Bureau of Development, there seems to be an autopsy room or something.

Ha, I don't know why the Bureau of Development is so small.

"Yes, sir. Let's not cheer up without the guest of honor. I've never seen a guest cry at a birthday party."

Indeed.

Why don't we celebrate seriously? Birthdays are to be rejoiced and celebrated if they are before the age of twenty.

After that, the fear of the "thirties" is gradually approaching, and before that, enlightenment is opened.

"In the meantime, it's a gift from me to Mr. Yayoi. I hope you like it......"

and Mr. Sophia handed it over from the bag.

"... clock?

Zenmai-style clock.

It has an antique design and is well-crafted by the way. I can't say it's an exact watch, but if you try it as a craft, no complaints.

Thinking I was about to give you the drawing table, I think I've made a lot of progress.

"You may not need it now..."

"Yeah. Glad...... thanks"

Saying, Mr. Yayoi turned his smile to Mr. Sophia. Probably not a lie or a lie.

I saw that. Mr. Sophia blushed for a moment,

"It's worth the effort."

I replied.

"... I think I know how Akira feels. This smile is cowardly."

And I said something weird.

Mr. Yayoi didn't seem to hear you, leaning over his neck and putting a question mark over his head, but you don't need to know.

Let's just tell Mr. Sophia "Welcome" for now.

And, that's when Leona slapped Pong and his hand.

"Oh, yeah. I've got something for you, too!

"Gee."

"Wait, what's that reaction?"

"No, you're definitely not busy, are you?

It's not a skeleton specimen (real) or a machine that explodes when used incorrectly, is it?

"It's a shame, but it's a busy thing. Yes, this!

And what Leona had offered Mr. Yayoi, who was frightened, was something familiar.

But this is the first time Mr. Yayoi has seen it.

"... what is this?

Even with Lori, Yayoi, a researcher, is immediately intrigued by the mysterious object.

"Huh! It's an invention of the human army called" Ra 'o "!

Why does Leona look like a doorman?

The radio you brought in is obviously the same as when you were brought to the station. And the "radio" pronunciation is suspicious.

"Ra... Ra...?

Mr. Yayoi, on the other hand, is blind to Leona and the dishes and cakes in front of him at the earliest opportunity, tapping the radio he receives and manipulating knobs.

And the operation worked, and audio came from the speakers.

"- by - and, Ki - including Congressman Berg - submitted the divorce papers - dated - Monday -"

Apparently, I picked up a national radio wave somewhere.

I guess it's just pretty far away, the noise is terrible and I can barely hear the content.

"Of the human army, the Magic Communicator......?

"It's a shame. That's for reception only. And I'm not a magician."

"Huh?

Cute.

I will also give Mr. Yayoi the radio description I explained to Leona and others before.

"... that's funny. If you understand the language, you will also progress in gathering information."

"Right. That said, there won't be any military secrets drooling over the waves."

"Yeah, but didn't you manage to tell Akira before this that there's something called 'Ransu-Ho-Soo'?

"Random number broadcast? Well, I told you, that's because it's encrypted..."

And I also told Mr. Yayoi, who looked strange here, about the random number of broadcasts. And there, I realize there's Leona.

"Oh, maybe there will be another. It's random numbers. In time."

"Hmm? Oh, right. That's gonna be on the air on a regular basis. Well, sometimes the channels are changing or the time is changing."

However, due to such anxiety, random number broadcasts continued to flow as usual today.

That's why a second random number broadcast viewing meeting was held abruptly.

In the usual time, on the same frequency as usual, with strange and creepy music and audio, the numbers came to light.

Unlike earlier news, is it in that audio is less noisy and clearer?

"... you're scared"

And the first word of Mr. Yayoi's thoughts was that.

"I certainly don't want to hear it in the middle of the night."

"Yeah. But it was funny"

Mr. Yayoi seems to be the type to fall for amateur radio.

And then you mess with the radio, and you hear me say, "What's going on with that?" "What does this mean?" "Can't you do this?," etc., was on question-attack from Mr. Yayoi.

I didn't have a clear answer with me because I'm neither a radio expert nor an amateur radio guy, but I answered her questions as far as I could answer.

The question, which was particularly feverish,

"Can't you identify where it's coming from or something?

is.

"There is."

"What?"

"It's triangulation by wireless directional probing."

There is a vector in a radio wave.

If you can see that vector, that is, where it comes from and which direction it intends to take, if you follow it in reverse, you can see the direction of the origin. If you do it in more than two places, you can identify the exact location using triangulation procedures.

That said, can this method be used in the Demon King's Army?

At any rate, radio waves are not visible. Nor do they have the tools necessary for wireless directional exploration. In the first place, the Demon King's Army, including me, is ignorant about radio waves.

"So I think that's hard."

And I answered once and for all.

But I know that the curiosity of sleeping behind Mr. Yayoi's eyes is not something that disappears so easily. This is Leona's face when she looks up close and tries to create a new weapon with a great deal of determination.

Mr. Yayoi's two ears and two tails touching the radio were moving with pleasure.

Oh, this is going to be trouble again.
