“This floor is dangerous” (Celeste)
“Yeah, in many ways” (Ryouta)
“We should go to the next floor.” (Celeste)
Alice, Celeste and I all agreed.
Only Emily, who couldn’t recognize her black history as black history, tilted her head in confusion.
“Then, let’s go down immediately.” (Ryouta)
“Yes. If it comes out, I’ll leave it to Ryouta-san.” (Celeste)
“Leave it to me, I’ll defeat it before it transforms.” (Ryouta)
I hit my chest and took on that role.
Black history———would not always be just one.
From my experience of the first and the second floor, there is a high possibility that more than one will be drawn.
There are at least five or six remaining stories that are objectively “die smiling” to subjectively “oh fuck just kill me”.
Maybe Alice and Celeste are the same.
We hurriedly proceeded so as not to peel off the scab, which is our youth.
Because I understood the situation, I asked Alice to take the lead.
It should be possible to go downstairs with almost no encounter.
However, it’s not 100%, so I was ready to cast Repetition at any time.
Fortunately, we arrived at the stairs leading down without encountering any monsters.
“Phew 
” (Ryouta)
“I’m tired” (Celeste)
“Me too.This might be my most tired since starting as an adventurer.” (Ryouta)
“Then should we take a little break desu? I’ll prepare tea and snacks desu.” (Emily)
The angel of my home has made a fascinating proposal.
Normally, I would ride on it.
“No, let’s go down.” (Ryouta)
“Yeah, even if we want to take a break, at least take it downstairs.” (Celeste)
“Agree” (Ryouta)
“Is that okay desu? I remember Yoda-san saying that, “Just a little more, just one more floor” is a flag nanodesu.” (Emily)
“Ughh.” (Ryouta)
I was struck by a painful part.
As Emily says.
It is common to say “just a little more” and get the consequences.
A few years ago, “Let’s go home, we can come back again” became a revival boom, and this way of thinking has become more commonplace.
“HO-WEVER!!” (Ryouta)
“People sometimes need to take a courageous step.” (Celeste)
“When is that? Obviously it’s right now!” (Alice)
Emily, who proposed to take a rest, was desperately turned down by Celeste, Alice and I.
“I-I understand nanodesu.” (Emily)
As a result, Emily had to agree, and we decided to dive to the fifth floor without resting.
New floor.
The front is me with Vanadium.
After that, Celeste, Emily, and Alice are always ready to call Ryo-chin.
We went down the stairs in that order.
Carbon dungeon, 5th floor.
“

Hmm?” (Ryouta)
“What’s wrong with Ryota-san” (Celeste)
“Something 
 feels off?” (Ryouta)
“Eh?” (Celeste)
“What’s the difference desu?” (Emily)
“Hmmm.” (Ryouta)
“I think so, I don’t know, but it’s different.” (Alice)
“So you feel the same Alice.” (Ryouta)
As soon as I got off, I thought something was differentt.
Emily and Celeste didn’t seem to feel it, but Alice, born in the dungeon, did.
“If Alice says that there’s something wrong.” (Celeste)
“Yes. Do you know what that is desu?” (Emily)
“Hmm, I wonder. The only thing I know is that it’s different.” (Alice)
Both Alice and I looked around the dungeon.
A stone dungeon, a pale blue light that blinks repeatedly.
The appearance is exactly the same as the upper floor.
“Let’s compare the two.” (Alice)
“I will do that too” (Ryouta)
I went up the stairs with Alice and returned to the 4th floor.
We stared at it and burned the sight of the 4th floor into our eyes, then went down the stairs and returned to the 5th floor.
We compare the scene that was burned for comparison with the 5th floor.
“Hmm. I don’t know what’s the difference.” (Ryouta)
“I am the same. But
” (Alice)
“Yeah, I’m sure something is different. I’m more convinced.” (Ryouta)
Alice and I nodded to each other.
It was like “somehow” we know.
However, thanks to the fact that I burned my eyes and came back to compare them, I was convinced that they were “certainly different” even though I didn’t understand the same thing.
“If we don’t know then it can’t help it, but let’s be careful.” (Celeste)
“Yes, it’s on the 5th floor, so it’s not weird if something changes desu.” (Emily)
The two believed us even though we made no sense.
“Okay, then let’s be careful” (Ryouta)
“Yes” (Celeste)
Celest responded and both Alice and Emily nodded.
I thought we would proceed carefully as declared.
“Oh you’re here.”
Neptune came down the stairs while waving his hand.
“What happened?” (Ryouta)
“What did you do over there? In the last ten minutes” (Neptune)
“This ten minutes? Well, not much. Rather, we just stepped foot on this floor.” (Ryouta)
“Hmm,  I see 
 then you’re not the one, is it our behavior?” (Neptune)
“What do you mean by that?” (Ryouta)
“Actually” (Neptune)
Neptune was smiling, but he had serious eyes.
“The entrance has closed again.” (Neptune)
“–!” (Ryouta)
☆
I stopped exploring the 5th floor for the time being and returned to the 1st floor with the Neptune family.
We came back to the entrance of the dungeon.
It was completely closed and was just a wall.
“It’s really gone” (Ryouta)
“Emily, try hitting it” (Celeste)
“Yes desu!” (Emily)
Prompted by Celeste, Emily swung a hammer overhead and rushed, hitting the wall where the entrance was.
The best power fighter in the family is Emily, but the wall didn’t leave a dent.
“It was the same when we were first trapped.” (Celeste)
“Yeah, Celeste was from the inside when she was first trapped.” (Ryouta)
“Yes” (Celeste)
“I see, so this was happening 
” (Ryouta)
“What will you do?” (Neptune)
“Let’s go out” (Ryouta)
I loaded an Iron wall bullet and a Vanadium bullet and ‘opened’ the entrance through the wall.
After making it large enough for people to pass through, the Neptune family, my companion, and finally me.
When we all went out, the entrance was restored, leaving behind the Iron wall bullets.
“One thing has been confirmed” (Neptune)
“Yeah, the entrance will return when there are no more people inside.” (Ryouta)
“In that case, there should be a condition as to why it closes.” (Ryouta)
Neptune nods.
The rules of this world are quite precise when “Drop S” is not involved.
“Thanks to you, it’s almost as if I knew something that was up after a dozen minutes.” (Neptune)
Neptune smiles.
It doesn’t matter if it’s because of me.
If that is the case, let’s verify that the possibilities are narrowed down a little more.
