Before we left the house, we found a hidden staircase, and we went down that staircase.

What was ahead of me when I got down was the room again.

That's also the room where the body is firmly laid on the floor.

Everyone was naked.

The smell and the harshness of the sight make me puke.

It's not the same kind of cruelty I've seen, it's a sight.

"Gas chamber, huh"

Again, I think my sister is amazing.

"The gas chamber, you know, the Empire was doing it during the Great War, are you?

It's a room famous for massacring certain ethnic groups, easily learned in videos and textbooks of teaching materials in a class in world history.

"I don't know if the features are the same.

But the meaning is, the same. "

My sister lets some pale demon squares unfold.

Just like in the first room, the demon squares floated around and moved around in that room, eventually disappearing.

"I wonder if this was the disposal site"

Disposal site.

Is it that he was disposed of?

And, then, this sight.

So, I'm hallucinating the sight of myself in that corpse.

If the times of birth were different, I guess I was here too.

And as a subject of some kind of experiment, was it over?

Oh, my God, I'm delusional.

Does that make sense?

Last as a subject.

Did that happen, was it bad luck or bad times?

I don't know.

Also, nausea comes in.

"The first rotten or moving corpse earlier was fine, but I don't know your criteria"

I answer to my sister's words when she vomits.

"I don't know either."

But that's probably what it is.

When I wipe my mouth with my sleeve, my sister gives me a bottle of pet with water.

I whispered with it.

"Nevertheless."

My sister said.

"It's like I just died.

It's not rotten. "

I don't know how many minutes ago that was.

I mean, that doesn't seem to mean the body's been damaged that much.

"If I told you it was fresh here, you'd be suspicious."

"It's okay, it's okay. Because there's no one here who doubts your sister's personality."

Well, I think it's black humor.

I said, opposite my sister, looking at the stairs.

Because I'm going to throw up again.

"Don't move."

The man whose neck was lifted can move, and the body that is (appears to be) dead here can't move, because it is certainly odd.

"Isn't that because you were disposed of?

"When that happens, what happens to the man whose neck was hanging earlier?

"Uh, you want to ask me that?

My sister spins her head faster, so this question didn't seem to make much sense.

"If that's what you were experimenting with here, isn't that a success story or something?

"Is that a success story?

My sister tells me to think again.

I immediately remembered if there was any.

No, I don't know what kind of research you're doing.

But with his neck hanging, he said he was alive.

Hmm, that's the study of immortality??

Uh, no, it was on a beautiful star, and a mad-scientist doing research that doesn't die is a novel in the dark.

It was so thick that I said it was a box.

From books for children to books that seem to be suitable for reading in coffee shops, I guess it's Arre Absolute Master's hobby.

That, too, was a limited number of readers because it was mostly written in exotic letters, including picture books and comics.

We were able to read it because my mother could read it, thanks to her reading.

"You're studying demons, too?

My sister continued.

It was closer to whining than asking.

"Isn't that what you're doing in research that won't kill you?

Look, the study of immortality. "

I joked half the time.

And then he mouths what he remembers.

"Look, how many years ago?

Immortality or the study of immortality went too far, an elf student was attacked, there was a serial murder??

Doesn't that feel like it?

I think it was definitely a foreign story.

There were many cases of Elves missing, and some time later they were found dead.

It's called serial killer.

After the investigation, the killer was captured and the death penalty was confirmed. It became news that it had been executed.

Elves, or long-lived species, were targeted because of their immortality close to immortality.

"Uh, there was.

He was eating it while I was studying it.

Well, it looks like we weren't going to eat here at least. "

Exactly, I couldn't laugh.

Yes, at least if you just saw it earlier, there's no sign of it like you ate.

The study of immortality and immortality in the first place is also only a delusion of mine.

"But so-called [non-dying research]?

I see.

But hey, um? Something's catching on. "

"With that said, you see, the research that used to be done here during the war, or human experimentation, it ended up?

"Well,"

My sister kept her mouth shut for a while.

As much as possible, I look back at my sister so she doesn't see the bodies laid on the floor.

My sister acted as if operating a mobile device in the air.

Eventually, you're done. Looking back at me.

"Anyway, let's go outside and find out.

It's always been a horror genre to die in the same place. "
