Chapter 5
"..."
I reread the notebook in front of me.
No. 151?
No. 152?
Did that mean someone had come after me?
How did that make sense?
Wasn't I supposed to be the last one?
I hadn't even died.
Then how could I see records written by people who came after me...
No.
I didn't even know if they had actually come after me.
How was I seeing their records at all?
Don't tell me...
"..."
I hurriedly stepped outside the elevator.
The mascot, which had been standing quietly until then, trotted after me.
"Do you know something? Are more people kidnapped here even if I don't die?"
"...?"
The mascot tilted its head.
"I mean, am I not the last one? Is there really a No. 151?"
"...?"
It stared at me like it had no idea what I was saying.
I sighed.
Right.
My fault for expecting an answer.
Let's think.
There was someone after me.
And they said they were going to the second floor.
It sounded insane, but that meant someone was currently on the first floor.
And that person was going to come up to the second floor.
There was only a small chance, but...
What if...
Just maybe...
Someone really came up?
What if I met the person coming from the first floor?
Wouldn't things become easier?
At the very least, I'd have someone to talk to.
The mascot understood me, but it wasn't exactly capable of having a conversation.
"..."
For now, let's read more of the notebook.
I scanned through it.
The contents were still mostly the same.
A maze.
And apparently, there was no method other than wandering until you found the path.
Still, after rereading everything several times, there were a few entries that seemed suspicious.
[83. I think there's some kind of pattern. But even if there is, you still have to wander around to find the path... and the steam makes walking pretty hard.]
[121. I'm ■■, so I've just been walking nonstop. But once it gets hot enough, don't the pipes start making way too much noise?]
[130. I think there might be some cooler areas. I don't think I'm getting out, though.]
Three entries.
"..."
I tapped the elevator wall while thinking.
There was a pattern.
When the temperature passed a certain point, the pipes got louder.
There were cooler areas.
"I don't know."
That was far too little information.
I frowned deeply as I thought.
Then, almost as though it had been waiting for me, the announcement started.
<Further waiting is not permitted.]
<We repeat. Due to the characteristics of the second floor, further waiting is not permitted.>
<If you remain inside the elevator until the doors close, we will not be responsible for any accident that occurs afterward.>
The doors began closing.
Once again, the mascot, which had been standing still, grabbed my wrist and dragged me out.
"I can get out on my own."
"..."
Without answering, it simply pulled me outside.
The moment I stepped out, the elevator doors began to close.
A few seconds later...
Thud.
They shut completely.
"...Phew."
I looked at the closed elevator doors and sighed softly.
Let's wait ten minutes.
Exactly six hundred seconds.
Who knew?
Maybe someone else would come up on the elevator.
Thinking that, I stared at the doors.
The mascot beside me remained completely silent.
It just stared at me.
Exactly six hundred seconds later...
"Nope. Not happening."
Apparently, waiting here wasn't going to let me meet No. 151 or anyone after them.
Maybe...
"...It's like parallel worlds or something."
I didn't really understand the theory.
But I'd seen it plenty of times in movies and books.
Or maybe there was some other rule I didn't know.
The important part was this.
People were coming after me.
And they would act based on what I wrote in the notebook.
"..."
Did that mean people's lives depended on my words?
"Let's stay a little calmer."
"?"
"I'm talking to myself."
In the end, I had no choice but to move forward again.
But that was fine.
I'd already memorized the path.
"Last time, it was left, right, right, left..."
This time, I'd change things slightly.
Time was on my side.
If I died, I could try again.
For someone rich in time like me, this floor was basically something I could clear eventually just by repeatedly trying.
Dying was unpleasant, though.
"If I'm suffering too much, can you kill me?"
"..."
The mascot vigorously shook its head.
As though it couldn't do something like that.
"Is that so?"
Too bad.
This place really was easy to get lost in.
Every path looked almost identical.
If I hadn't memorized my route, I would've gotten lost in no time.
The temperature had risen slightly.
I kept walking without stopping.
"Haa..."
Hot.
I stopped briefly and caught my breath while watching steam hiss from a nearby pipe.
The mascot behind me also stopped.
It quietly stared at me.
"Isn't this hard for you too?"
"..."
It sweated less than I did, so it was probably fine.
It didn't even seem human anyway.
Or was it?
"They say the parts touched by the steam melt, so be careful."
"...!"
The mascot exaggeratedly twisted its whole body to dodge the steam.
Thinking about it, the mascot's body was much thicker than a human's.
How was it so good at avoiding everything?
I watched it weave around the steam, then opened the notebook again.
Maybe more entries had appeared.
No.
Nothing new.
Still, I felt encouraged.
It was awful that more people had been dragged in after me.
But knowing they had solved things more easily because of me gave me strength.
I continued building a map inside my head.
"Right here, then left after this..."
"..."
"Dead end. Then since we came from behind, eliminate the left path and take the right..."
Remembering all of this was work in itself.
After walking for a while, the heat started rising again.
"...Hot."
I took off my jacket and tied it around my waist.
The mascot stretched out its arms.
"What?"
"...!"
"Ah. You'll carry it?"
"!"
It nodded vigorously.
Strangely helpful.
"Thank you."
"!"
The mascot raised a fist proudly, then took my jacket.
If it wanted to help, I wasn't going to refuse.
I wiped sweat from my face with my shirt sleeve and kept walking.
Though I was starting to think this attempt was probably doomed.
We continued.
The heat kept getting worse.
But that was fine.
"If we just find a path to the right here, then we'll..."
A new route...
"...?"
A solid wall stood in front of me.
