Celeste, Vanadium, and I returned to the mansion using the transporter gate that Celeste had left open once we got back to the mansion.

''Then, please,''

　I'll give it to Celeste, who has been to the third floor of carbon.
　Because of the vanadium, we had to go around the basement to avoid the second floor.

......
Celeste?
Will you wait for me here?
Hmm?　What do you mean?
I'll go and capture the third floor with the others and then come back and take Ryota-san to the fourth floor.
Why would you do that?　That's going to add to the hassle of going from the third floor to the fourth floor and then coming back from the fourth floor to the third floor, no matter what you think.
That's true, but ......

　For some reason, Celeste clammed up.
　What the hell is going on here?

All right, let's go.

　Celeste thought for a moment, then let out some kind of determined line in a whisper, "Yeah, if this is it," and then opened the gate to the transporter room.

　What in the world is this all about?
　Before we knew it well, the gate opened and the three of us were back in the dungeon again.

　Carbon Dungeon, third basement floor.
　It looks exactly the same as the first and second underground floors.

　It's an underground labyrinth made of piled up stones, with walls, ceiling and floor glowing blue-white.

　As soon as they transferred in, a monster appeared.
　The monster tried to transform against Celeste--.

''Inferno Ultimate!

　Instantly, magic power exploded out of Celeste's body, and the monster before the transformation was burned away in an instant.
　It was the highest firepower - a super-serious blow - of Celeste's magic that I had ever seen.

''Celeste?''
What is it?
Something, that doesn't make you drop anything.
It's okay. I'm not here to make money today.
Yeah, I know, but it's an investigation and all the more reason to--
Inferno Ultimate.

　Before I could finish speaking, Celeste cast another spell.
　Something went up in flames behind me.

　I turned around, a little freaked out by the suddenness of it all, and there the monster before it transformed was in flames.

''Fuu.''
......, um, explanation.
Let's go.

　He doesn't seem to have any intention of explaining.
　Celeste interrupted the conversation one way or another and walked off with a stutter.

''...... (Guigui)

　I was a little puzzled, but Vanadium tugged at my sleeve.
　Won't you go?　I don't know why, but I decided to follow Celeste for now, because I felt like she told me.

　Celeste is hiding something.
　It's definitely about the monsters here - or the drop items.
　Otherwise, there's no need to defeat it before the drop.

　Which would it be, I wondered for a moment.

　Thinking about it, I went after Celeste.

　Then I heard the sound of a heel clacking on the cobblestones with a click, click, click.

　The sound was gradually coming closer and closer to us.

'This voice is ...... ah.'

　Celeste and us standing still.
　Eve came out of the corner.

　Eve came running in and braked in front of us.

Sorry, did we make you wait?　What about everyone else?
......
Eve?

　Eve looked up at me and didn't speak.
　For some reason, that Eve's face had a blush on it that I don't usually see.

'What's the matter - ouch!

　I was careless and ate it.
　Eve's chop, a hand blade called Excalibur.
　It was pretty painful as it went right into my forehead.

'You're low level and cocky,'
"Huh?
"Cheeky.

　Repeating the same words twice, Eve hung up even more tremendously as she ran away.
　Just before she ran away, her face seemed to be getting redder and redder .......

'What's going on?'
I see.
'What?　Celeste, do you know the cause?
...... I didn't say anything.
'No, but ......'

　...... Well, okay.
　If you don't tell me, I won't pursue it.
　Celeste and Eve are both a bit out of the ordinary.
　That's probably because of this carbon third floor.

　Then let's get the hell out of here and head to the fourth floor.

We'll meet up with the others.
Yeah.

　Celeste nods.

　He walks off, hand in hand with Vanadium.
　After a while, he joins everyone - but.

''Huh?''

　I was puzzled.
　The remaining two who had joined us, Emily and Alice, were blushing as soon as they saw my face.

'You're home ......'
Lyota Osoiyo. ......

　The two of them are blushing and their tone of voice is more moist than usual.
　When I turn around with a huff, Celeste is in a similar situation.

　And for some reason Neptune is grinning a little further away.

　I thought it would be best not to get too deep into ......, I thought.
