The basement of the mansion at night.

　After dinner, I sneak into the basement alone.
　At the far end of the basement, at the far end of the basement, I put the key out of my pocket in a remote place.

　The key dropped by Prumbum's dungeon master, a guy who looks like me that she (Prumbum) has beautified by 10000%.
　I've tried many things since then, but it didn't work as an item at all.

　Then I decided to discard the normal effect and try to strengthen and regenerate it by making it into a haggler with drop S.

　So I came to the basement by myself.
　Sneaking around, avoiding my friends.

　Because--.

'Ah, Lyota, there you are.
'What are you doing, Emily has baked cookies. Come on, let's get back to the salon and have some tea.

　The jovial duo, Alice and Aulum, showed up.
　Ever since Aulum teamed up with Meeke and their actions were no longer restricted, they've been working together more often than not.

　Both have a jovial, upright personality, yet they both carry around adorable monsters.

　They've become like sisters, or maybe even best friends for years.

　The two of them came looking for me - at the worst possible time.

　A rusty key in the back hatched into a haggler over time.

"Wow, what's in the air?
Dungeon Master. You've come to the wrong place at the wrong time.

　The two of them felt the air and made an apologetic expression - but only for a moment.

'Whatever it is, hahahahahaha,'
'Pfft ...... Lyota?　It's Lyota.
'Lyota's sparkling, she's carrying a rose on her back. Geehahahahaha.
Don't laugh: "Don't laugh. ...... Pfft.

　The two of them laughed hugely when they got a clear view of the dungeon master, me, a 10000% beautiful me, and the dungeon master.

''Ah funny ...... ri-ching!

　For some reason, Alice used the summoning magic 'All Might' to call Ree-chin.
　At this moment, a total of three people, me and my two pathetic bodies, existed in the basement.
　This scene of all three of us meeting together is quite intense.

"What's the matter with you, calling that girl out of the blue?
Hey, this girl over here looks like a real ryo-chin, right?
Yeah, for all intents and purposes, you look like a 'ryo-chin'.

　Alice and Aurum get on well with each other. It looks like they have the same naming sense.
　I'm not sure what kind of face it is to have a "ryochin" face, but it's not hard to understand.

So I was wondering what the name was.
Of course it's .......
Yeah.

　Alice and Aulum, they nodded meaningfully to each other, then.

''Ryou-sama.''

　Unisoned.

　It's like oops .......

　I knew this was going to happen, so I had to sneak it in, and then I ended up being found and messed with.

Lippetishon ......

　I got discouraged and defeated Ryou-sama with my strongest round-robin magic.
　Hagremon Ryo-sama disappeared and dropped a golden key.

　It was the same shape as the first rusty key, but its color had turned golden and was glittering.

''Oh no, I beat it.
'I wanted to see some more. Hey, come to think of it, could Ryota use summoning magic or something?
'What?　I don't know, why?
If you can use it, you can call up a white horse at ...... and ride it, doesn't it look good on you?
'I'm in!　Oh--there's the bicorn!
The White Bicorn!　Ryo-sama and the bicorn. Nice, looks good on you.

Please don't.

　I'm getting more and more discouraged.
　The excitement of the two of us is hard to take right now.

'It would look so picturesque without the white horse, though.
Hey, I'd like to invite a famous painter to paint. Oh, maybe a statue or something.
Car-- ha!

　I ran out in a flash.
　I ran out of the basement and down the hallway.

"--

　There was a cell outside the window.
　His eyes met mine and he ran off like, Shubba-baba, and I was like.

'...... seriously?'

　I was desperate, and I gave up.
　The family that controls the minting rights in this world, even more so.
　Sel Sel Stema.

　He's an incredibly important man, but for some reason he's a big fan of mine, and he has a statue or figure of my "exploits" at every turn.

　I think I've been seen.

　Ryo-sama, he's going to be a figure!
　What a rambunctious announcement came into my head.

　I slumped my shoulders and trudged back to the basement.

'Welcome back, what's up?'
Let's go to .......
That means she's going to be a statue!
Why do you look so happy: ......

　Giving up reached the finish line and we laughed as we circled around.
　We can't do anything about that one, let's just forget about it.

　Let's just forget about this one - let's forget about Alice and Aurum, too.
　They're friends of mine ...... so let's forget about them.

　More importantly, it's a drop.

　I took out the golden key that Master Ryo dropped.

"That's the item you dropped, right?
Yeah.
What's it all about?
''I don't know. I'm guessing it's powered up because it's changed from a rusty key to a golden one, but I don't even know the original .......

　I kind of took the key and twisted it as if to unlock the door.
　Then - a door appeared.

　A door appeared in the basement of a large, empty house.

"What is this!　It's like a secret room!

　Alice was very excited, and the monsters on her shoulders were adorably excited.

　I, on the other hand, took a closer look at the door.
　A door that stood in the middle of the room, dawning like a sample product.
　There was a number on the door that read '01' in calculator-like typeface.

I wonder what 01...... means?
I guess that means only one of us can come in.
'Or I'll just put it in once--usually one of those two things.
Let's go in.
Wait. Awlum can wait.
Why not?
'It's possible that the door is a dungeon attribute. Even though Meeke is there, there could be a risk in that case.
......

　Aurum's lips twitched, but she withdrew with good listening.
　Dungeon attribute is a term I just made up, but he knows very well that she, as a spirit, disappears when she enters and leaves the dungeon, so he understood it right away.

'So it's me or Lyota, then.
Yeah.
Okay, I'll do it.
Are you sure?
'Yes!　Something about ...... smells really exciting.
I see.

　I knew it was a dungeon attribute.
　Alice, who was born in a dungeon, can wade through many things in a dungeon with a different "smell".

　Because she says so, there's a good chance that the other side of the door is a dungeon or similar space.

So let me go.
All right. Have a good day.
'Yes!　Well then, Aurum, go ahead.
If you're okay, I'm next.
I love you!　Here you go!

　Alice opened the door and walked in, keeping the tension high.
　As soon as she entered and the door closed automatically.

'01' turned into '00'.

'That's down,'
I don't know if it's the number of people or the number of times, but if it's 01 and 00, can it be increased, how?
Like, do you want to repeat the 'cat-and-mouse' thing, Master Ryo?
I don't know if I have a choice, but--

　While poking around, I thought it was one of the possibilities.
　Defeat that dungeon master and increase the number of people with more keys to increase the maximum number of people.

　Other than that, it's the passage of days.
　A pattern where the number increases and recovers, like 1 or 2 every day.

　We'll need to examine that area in detail as well...

Justadaima!

　About a minute after she walked in the door, Alice returned in high spirits.

'That was fast, how was it?'
Yeah, well, you know, how long have I been in there?
How long: ......
...... for a minute or so?

　I looked at Aulum and each other and nodded at each other.

'Hmph.'

　When Alice heard that, she became more and more hyped up.

''My God!　I've been in there all day!

　Alice put her hands on her hips and stuck out her other hand to make the V-sign.

　-- and a day inside?

What's going on?
I found an explanation inside. It said something about a day inside being a minute outside.
Hmmm, not sure.
...... No.

　I know exactly what you mean.
　It's a dreamy, dreamy room that a boy my age would dream of at least once.

　And there's a number on the door that says "00".
　This door, this room.
　I want to know more about it, I thought strongly.
