The Demon King Navy's new Ice Battleship No. 501 dates back about a month from the start of its construction, or about six months from the completion of its "Hydra," February 10.

I think the beginning of it all was probably that day.

Naturally, I didn't think that would happen at that time.

It was the first day off in a long time and I was supposed to take it easy at home.

... As you know, my dear home is the hypnotic room next to the barracks bureau office.

The commute time of 0 minutes is nothing better than the charm of being swayed by a full train over two hours each day, and I can't care less about using my unpaid salary to buy a used apartment in the Devil's Capital.

And the lifestyle cultivated during the company livestock age continues even after being summoned by different worlds.

I mean, say what you want to say,

".................. I got up early as usual even though I was off"

If you look at the somewhat old smelly pendulum clock, it's only 6: 30 in the morning.

Even the sun is still asleep in the latitude of the Devil's Capital, Groth Stadt, but when you come with me...

Dominus of a Megadeus said

'You may sleep slowly until after noon. That's what a free man is.'

Apparently, however, people who are summoned by the Demon King and engaged in barracks operations without freedom of professional choice are not covered.

Well, fine.

I think the only good thing about this sad lifestyle stained with livestock lies in letting the world know how wonderful it is to sleep twice.

That's why I go to bed, gentlemen. Because you're a free person, until after noon...

"Akira! Hey, Akira, you awake? Hey, Archira!

I wanted to sleep......

The sound of knocking on the door many times, and a slightly taller voice interfering with the time for a restful second sleep.

Son of a bitch, I don't remember asking for a morning call, and I want you to wake me up on board sleeping with Mr. Yayoi, even if I ask you to keep doing it.

Leona go home.

"Oh, you don't have a key to this! I'm not going in! '

"I'm not going in, I'm not..."

No, really, I want you to go home.

"Oh, I'm awake. I'm awake. Sophia's right. You're up early."

"That's why I really think you should go in..."

Ruthlessly the door was opened, and it was Leona and Sophia, who were on duty today, who entered my room.

Just leave Mr. Sophia and Leona just go home.

"Um, excuse me, Master Akira. I stopped..."

"No, that's fine. I was awake before Leona woke me up."

Besides, the drowsiness to sleep twice since Leona arrived seems to have flown 10,000 feet to the other side.

I have no choice but to wake up.

"So, what's it been all morning? It doesn't seem like a big deal anyway."

"Hey, there's something human Akira wants you to see."

"... ho"

Not as me at the station, but as me as a human being, huh?

I guess I brought you some trouble again, here's my intuition. Well, that's a routine tea thing, too.

I'm not going to change in front of the two women for now, so once I get out, I'm going to change into my usual suit and head out to the barracks office.

There were several bureaucrats in the office, Sophia standing sorry, and Leona putting a familiar machine on someone's desk in the bureau.

"Wait a minute. Because I have recently learned how to use it. Er, sure..."

That's what Leona said and ready to install, but I knew what that "machine" was before it was explained.

The machine is not that big, yet not even small box-shaped.

On top of the box, metal wire made a quadruple rhombus, and on the front of the box there were several dial-shaped knobs.

Leona is manipulating that knob.

That much explains it, and I think you can tell, even if you're awake.

And I guess Leona's done getting ready.

Light music came from the box along with unpleasant sounds like sandstorms. She had her chest stretched to her satisfaction, and she looked...

"Huh. This was successfully captured in an earlier small-scale offensive against the human army."

"That's a radio. No power and the scientific power of the human army, it would be Ore Radio."

…………

- I just tried to explain, and when I interrupted and canceled the doya face, it solidified with an indescribable look.

Kind of funny.

"It's... is NRBC, at lunch... in tin time... at first, depending on what the Kingdom Land and Sea... stands for..."

And then came the news of a radio broadcaster called NRBC.

It was hard to hear a lot of murmurs, but there was a lot going on in some empire that communism was being erected, like the kingdom and the Yakuza had defeated the Demon King's army, and the politics of the Federation and Yakuza were confused.

The human army seems to be in trouble, too.

To say that the Devil's Capital was at 6: 30 in the morning and the NRBC broadcaster ran the noon news, the time difference was more than six hours.

Since there is a difference in longitude of 60 degrees, it would mean broadcasting quite remotely. Is it a short-wave broadcast?

"... Dear Akira, you know, even if you think about it by yourself and you're convinced by yourself, what is it?"

"Oh. Excuse me."

So explain to the two of you that this is a machine named "radio".

Radio broadcasting on Earth began in the 1920s.

It feels somewhat like future technology because of the scientific power of the human army in this world, but it wouldn't be strange to have a public broadcast, depending on the level of penetration of the receiver.

Well, still, "broadcast" doesn't seem to be out of military range yet. How many years from here will traffic information flow to the radio waves?

"So, what happened to that radio? I don't suppose that's why you beat him up, huh?

If that's the case, I'll hit Leona with all my strength.

"Oh, yeah. Don't look like you're going to grab me like that. Because there's a good reason."

"Is that a good reason?

"... I want you to convince me after I hear this. I don't understand the language of mankind, so I want you to listen to Sophia and Akira."

"Ha... I heard the radio, but it's no different than the paper, okay?

That's what I said, but Leona frowned and talked with her head in poly.

"Hey, there's a weirder broadcast."

"Weird? You could understand the words, but they're odd?

"Yeah. That's how odd it is. I don't know, too pale...... Anyway, listen."

Strange, pale, radio broadcast......

Could that be......

I was thinking a lot, and Leona moves the knob again to change the frequency.

And a few minutes later. The strange broadcast came from the radio station earlier that I changed it.

The first thing that has flown is music. However, it is not a normally composed song called A Melo, B Melo, but just repeatedly streams a passage of the song in a broken Orgol-like tone.

After playing that strange song a few times, a woman's voice was heard. In what Leona calls "bizarre" and "pale voice,"

"5 6 3 2 0 5 6 3 2 0 5 6 3 2 0 5 6 3 2 0 5 6 3 2 0 5 6 3 2 0 -"

and even read out the same few columns.

"Apparently this is a number. I don't think it's a meaningful few columns, but it's flowing the same ones over and over again."

And, Mr. Sophia, who can understand the language of the human army.

"Doesn't that make sense?

"Yep. I'm even just saying '5 6 3 2 0' - oh, you've changed the numbers a little now. But I repeat the five-digit number twice, and I'm just saying it's pale."

Beside what she explains, I looked up to heaven.

Somehow, crossing radio broadcasts, which probably would have just begun, and putting broadcasts like this on the radio quickly already means that the human army is quite successful, too.

"Akira? Why do you look like that?

"Oh, yeah, kind of. I remember this broadcast."

"Really!? What is this! Sophia said you're only flushing numbers, but maybe there's something behind it!?"

"There is - and they say"

"Yes?"

Radio broadcasts that only continue to spread this number existed on Earth as well. Caller unknown, purpose unknown, recipient unknown, content unknown.

A mysterious monstrous broadcast where everything is "unknown" and only its existence is known.

People called it "random number broadcasting".

"... what's that?

"I don't know. But it's also known as" Spy Broadcasting. "

"Does that mean you're giving information to a spy whose army is out there somewhere?

"Understandable and helpful, Mr. Sophia"

A system in which spies infiltrating an enemy country decipher and obtain information based on random numbers tables, using rows that the average person does not understand.

Radio is an invaluable radio receiver for spies who can't have massive reception facilities in the pre-mobile world, even in the 21st century.

Easy structure, convenient and small.

Short-wave broadcasting allows radio waves to reach the back of the planet even with small output power. It's a means of contacting spies by hitting them.

That said, there is no way that this information can be made public because of the anomaly of its broadcasting, and it is all speculation. There's also a theory that it's by drug trafficking organizations, not intelligence agencies.

"Either way, do you mean we don't understand"

"That's the thing. I don't know if this broadcast is about us."

Or because there are a lot of random number broadcasts, there is no specific choice.

"But isn't it impossible for the human army to spy on the Demon King's army? 'Cause if you go in there, you can see that you're human, and you can't get away with it."

"Yes, you are."

Leona is right, humans can quickly distinguish from demons and subhumans. In fact, as soon as I get down to the Devil's Capital, I'm in a lot of trouble.

Thinking about it, would this broadcast be called Negeva between the human armies......

If I had talked about things like that, at some point the broadcast was over and I could only hear the sound of a sandstorm.

"Hmmm, kind of indigestion......"

Leona is unhappy, but it's been a long time since I've heard an interesting broadcast, so let's not ask what was caused.

So I go to bed twice.

Don't let it happen except in enemy attacks.
