In response to the word "Holy Demon," Katie begins her investigation of the relic with great joy. Hikaru went down to the ground with Lavia and Paula because there doesn't seem to be any other Japanese descriptions and Celica is still on the top floor.

I needed time to sort out my thoughts.

(Build a radio station means you should have scheduled a broadcast for a large number of people. The architecture of this tower alone involves quite a few people. However, the ruins of this tubular were later "discovered". What happened to the people who were here —— something that could interrupt history so easily?

The first question is "The Mystery of Radio Stations and Interrupted History".

(And the Holy Demon. Was the technology called Holy Demon common in the past?

The second question is, "What is the Holy Demon?"

(Considering that I'm Japanese who knows radio, I'm about 100 plus no matter how old I am. There were no old fonts in Japanese written on the wall either. But this ruin was built more than a few hundred years ago... I knew the timeline was off)

The third question - not the question, but mostly the answer - is "the unevenness of the Earth and the timeline of this world". Even though the timing of Hikaru's and Celica's metastases hasn't changed as much, Celica was here less than a year ago.

"Hikaru"

Lavia has spoken to me thinking about it.

"I know you originally intended to cooperate with Dr. Katie, but are you glad you taught the Count of Tubra that far?

"Well, I'm in trouble if you don't get this country to come together. I thought I'd behave in large measure if I was to leave you with a whiskey. Besides, I was worried about what was left of me and my hometown..."

What should I do when I come to another world?

That was also a major theme to think about for Hikaru.

"If you cooperate with the investigation, you'll bring a document from the other side saying, 'Read me this,' even if you leave me alone, right? If you read that, you'll know what he (...) was trying to do"

All of a sudden, I'm alone and I'm flying to another world —— what can people do?

What are you going to do?

Isn't he his mirror?

"... Hikaru"

Lavia has been holding hands softly.

"I am by your side"

"Oh, I know. Thanks."

Knowing that Hikaru was an otherworldly man, Lavia may have cared that Hikaru was feeling lonely.

"Wow, I'm here too! Dear Hikaru!"

"... right. And Paula, thank you."

"Huh!?"

You honestly didn't think you'd be appreciated, Paula glanced a little, then turned her face bright red,

"Oh, no, no, no! That's awesome!

I have to take a few steps behind my back.

"Well —— and that was nothing more than I thought. Well, after I pulled up everything I had left inside, I can't help it."

Katie is in the process of investigating, but there is little more Hikaru can do (she also said she left it all to Celica).

Looking around, the low mountains continued, with coniferous forest belts underneath his eyes and the city of Nekoha in the distance.

"Hikaru. The, the radio? Was it meant for the city of Nekoha?

"That's what I thought at first, too, but thanks for the different orientation of the 'plate'.... No, wait? Given the shape of the" dish, "I thought it was a receiver.

"Yeah?"

"The radio wave transmitter was like a metal antenna...... uh, I wonder how it went. —— When that happens, that 'plate' is oriented..."

Hikaru throws his gaze.

The "plates" attached to the top of the tower face towards the valley between the mountains and the mountains.

(... also "Valley")

It's where I was concerned when I came.

"Let's go to the valley"

Holding hands with Lavia, he also followed Paula from behind as Hikaru walked out.

"Oh, how far do you want to go? Guests"

A guard soldier comes and tells him, "Hey, to see what's going on up to the valley,"

"There's nothing over there, is there? This area is after a thorough investigation. There will be signs out there. Beware, the ground is loose up ahead."

He told me. He doesn't even want to stop it in particular.

Walk to the valley. There is a distance there from the tower, which is a relaxing downhill.

Then, I see, there was definitely a sign.

A blunt golden stick -- a round stick with a wooden sign attached to it. I'm concerned about the difference between the stick on the stand and what the sign does.

"Before this, the ground is brittle."

Hikaru, looking at the letters, finds out.

"This axle stick... isn't it what was originally here?

"What do you mean?

"If so —— this"

When I checked the signs, the wooden planks were just tied together with strings. Looks like those soldiers stuck together.

A 15 cm diameter wheel clamp is stuck at equal intervals to the axial rod about 1 metre high. The top edge shows signs of metal cobs connecting but broken.

"... Could this metal be part of the roof (...)?

I've seen this shape before. It's a metal ornament attached to the head of a pentathlon or temple building, a "companion".

The sticks here are vaguely built, not exactly shaped, but wouldn't that support "based on memory"?

I mean —— wasn't it made by the Japanese who were here?

"Did you say part of the roof? Even though it's buried in the dirt?

"--Lavia, that's it"

Hikaru flashed.

"The building is buried in this basement."

Hikaru wasn't sure if he should be able to reward Katie and the others for this right away, but I can only imagine that this metal stick is "compatible". I thought I'd do some more research.

(There's something buried beneath the ground —— if it's buried (...), that part of the ground is naturally loose.)

Hikaru heads to the valley. There were ramps down to the valley bottom, bypassing steep slopes and cliffs. As you go down, you can hear the water and it gets dim. They haven't received daylight to the bottom of the valley. Along the way, a few monsters appeared like Imori, about 50 cm, but when one was cooked by Lavia's fire magic, he made his way out.

"The road to the bottom of the valley is tightened. As that soldier said, it looks like you've been here many times."

"Why do you come so many times, Master Hikaru?

"I guess it's part of the patrol. Nothing protects that tower but its human counterparts. Even monsters destroy ruins. They must be crusading monsters by checking the bottom of the valley."

"I see."

"So we can look around safely..."

Valley bottom only about 10 meters wide. As long as there is a thin river. The water seems to be gaining momentum and I hear seyings everywhere.

"It was this way that there was that sign... Careful, Lavia, Paula. Scaffolding is bad."

Nor do the soldiers seem to have even made it to the bottom of the valley to walk. Dusty stones are rolling and hard to walk. When people ask me if there's anything ahead, I don't know. I've tried to follow my "intuition" to get this far, but of course even "surveying" can come off.

I went on for about 5 minutes. Give Lavia a hand she's about to fall over, stick her foot in the se and wet her shoes.

But nothing.

"... I guess that soldier's right"

"Nothing?

"Hmm... right. All right, let's turn back--"

"Dear Hikaru. There's a monster over there, like a muddy Lizard."

What Paula found was a fellow monster roasted by Lavia earlier. The imori, which was crashing on the slope, ran away when he saw the hikals.

"--Huh?"

I doubted my eyes.

Imori disappeared.

"Kid, disappeared? Why? —— Ah!

Hikaru activates Magic Detection.

"!! Yes! There's a cavity there --"

Looks like a steep slope without any weird philosophy. Enough to say cliff.

But Magic Detection had a clear reaction —— it was a blue curtain that covered the slope.

"Lavia, is there such a thing as magic to cover up a cave?

"It's magic, it's magic."

"Okay —— just give me a minute. I'll check it out."

Hikaru leaves Lavia and Paula, alone, approaching the blue curtain. It was just a slope of dirt in front of me, but when I reached out, I couldn't help myself. When I never stepped out of my mind, I was able to get ahead of it.

"Hikaru!?"

"Master Hikaru is gone!!"

"It's okay —— because I just went inside"

It wasn't dark inside. There's light coming in from outside the cave. From Hikaru, I can see Lavia and Paula coming this way.

Meet the two and the three of us cave again. The stretch of the cave is clearly in the direction of the sign.

"Wow... you had a cave here... it's like an adventure story about finding treasure"

"Isn't that a big discovery!? There might be a treasure!?"

"What do you do, Hikaru?

Lavia asked, and Hikaru laughed.

"Of course you can reward Dr. Katie and the others. —— But before you do, you can look inside lightly enough, right? as the first discoverer's privilege."
