D Genesis, 3 Years after Dungeon Appeared

"Damn it... what am I supposed to report?

Naruse Miharu was in trouble.

Here, the Dungeon Management Section Monitoring Section of JDA (Japan Dungeon Association) mainly deals with the generation of dungeons in Japan and the status of attacks.

It is said that new dungeons, albeit less frequently, occur about once a year in each area.

It was presumed that there were many dungeons that had not yet been found, since few countries, like Japan, had installed high-precision seismographs on a national scale.

I've heard that before, but...

"Just report what happened."

"Fu, the wind won't come!

Faced up, there was a beautiful boss there. Furai Sho, 29 years old. I'm the assistant chief of the surveillance section.

He was a young, nervous man with a retracted forehead.

"Especially if you're lost. Would it be confusing to incorporate random speculation?

Ha.

Yes, that's true, but the result is...

Beautiful was hesitant to report it as it was and she was likely to suspect her sanity.

"What is it? Don't wear it. What the hell is going on?

"No, um... well, I'll report it as measured!

That's why I told you to do it from the beginning.

You already know. I'll press my boss for the rest. Beautiful decided to start talking like water on the stand.

"At 14: 32, I caught what I thought was a dungeon near the new National Stadium."

"Right next to Yoyogi?!

The Yoyogi Dungeon was created three years ago between the NHK broadcast center and the second sports event at the Yoyogi Stadium.

"Is it about a kilometer in a straight line?

"So close? How big is it?"

"Uh, uh... depth."

"What do you mean?

"If the measurements are correct, the depth is more than 1400 meters."

"1400 meters?!

The dungeon depth of the Yoyogi dungeon is 280 m. That's roughly five times. There is no doubt that it is the best depth in the world.

"Well, then, the Oedo Line is in big trouble... contact all relevant locations immediately!

When the Yoyogi Dungeon was born three years ago, the Yoyogi Park on the Chiyoda Line was cut off from Harajuku, causing a major accident.

It's early on the afternoon of the week, and if the subway line suddenly disappears, it could be catastrophic. But...

"Ah, no, it's near Aoyama Gate, so it's probably safe."

Studies had revealed that the space actually occupied by the dungeon was cylindrical in diameter from a few m to at most a dozen m.

Dungeon vibrations are shocks when the needle is pushed in, and extinction vibrations are known to be shocks when the needle is pulled out.

From Aoyama Gate, it's just under 200 meters to the Oedo Line route. If the measurements are correct, there should be no damage anywhere.

"Nevertheless, we need a report. The entrance has to be sealed, and the impact on the arena under construction is inevitable. to the Olympic Committee."

Wait, please.

"What?

That's what I was asked, without hiding the truth about this fucking busy situation.

"That's it... it's gone now"

"What?

"So the dungeon."

The boss looked like a pigeon had eaten a bean gun. I thought my face when I saw the data just now would be like this, but Mitsui was facing the next storm.

"A deep dungeon appeared in the city....."

The boss glanced at his watch.

"Extinguished in an hour? Are you kidding me?

Mitsumi dropped her shoulders as she saw her boss laughing with a willingness not to forgive a joke.

"That's why I was confused about the report. Anyway, the deep dungeon that occurred near the Aoyama Gate of the new National Stadium at 14: 32 has already disappeared as of 15: 20. An extinction earthquake very similar to Denver has also been recorded. Just a few minutes after it happened."

After the last monster was defeated in Denver, everyone returned to Earth and after a while an extinction earthquake was recorded, it was reported that only traces of broken holes remained there.

Similar phenomena have been reported in shallow-depth dungeons that have been trampled.

"Do you want to say that someone showed up and attacked the deep dungeon in a few minutes?

"I don't know. I don't know, but the city's peace and schedule for the Olympics were kept. Isn't that good?"

Towards her stunned boss, Mitsui made up a conversation like that and lowered her head to say that she could not speak any more.

The boss who heard the report gave a serious look toward Beautiful.

"So, what do you think I should tell the section chief?
