After getting a dozen fruits that resembled the shape of a bell and putting them together and tucking them into the Grand Eater's pockets, he finally descended the stairs and stepped down to the tenth floor underground.

'...... First off, everything's clear,'

　What I came down to was the exact same, visceral looking dungeon as the one upstairs.

　The dungeon snow - the red snow is what's falling, but that's within the realm of normal dungeons.
　It was a bit of a letdown, as I had imagined it to be something much bigger and different.

　I figure out the structure of the dungeon.
　It was an intricately shaped, maze-like dungeon, with a staircase leading down at a distance.

　Is there still more to the Nihonium dungeon?

　I pulled myself together and walked off to encounter the monster.

　I walked a little differently than I did on the ninth floor.

　It doesn't make any sense, but when I'm just encountering them, I walk and look at them in a different way for no reason.
　It could be circling around in a circle, or going back and forth with two points in mind, or a combination of the two.

　It doesn't mean anything in particular, I just change it as I feel like it's appropriate at the time.
　I still walk differently now than I did on the ninth floor for no reason.

　As I was doing so, I met a monster.

'Huh?'

　I tried to make my way towards the monster, but I lost sight of it.
　It looked like a ball of fire floating in the air, which I saw a short distance away just before.
　When it tried to get closer, it disappeared.

　Or so I thought.
　I waited for a little while and it appeared as normal.
　Isn't it bad to get close?　And then I remembered the ninth-floor celestial demon and waited a little while as I stopped in place.

　But that guy disappeared again.

　After it disappeared and did nothing for a while, it reappeared a bit further away.

　I pulled out my gun and moved closer.
　It didn't react at all at first, and then suddenly it disappeared and reappeared again.

It doesn't seem to have anything to do with what we're doing.

　Since they weren't attacking me, I didn't attack them either, so I took a wait-and-see approach.
　Unlike the heavenly demons, they have been coming and going regardless of my actions and intentions at all.

"Human souls--or is it the foxfire one?

　I tried to use all my knowledge of the monsters and specters on this floor to try to guess the identity of the monsters and specters.

　It doesn't attack me, so I decide to test it some more.

　As soon as it disappears, I fire a conventional round into the spot where it disappeared.

　The bullet misses and lands in the wall.

"Hmm.

　I nod and wait for it to reappear.
　You wait for it to reappear, and then it disappears again, and this time you spread conventional rounds around the area instead of where it disappeared.

　And then one of the loose rounds "hits" you.
　In the air, it slowed down a bit as if it had hit something, and its trajectory shifted.

　Immediately afterwards, a thinly veiled human spirit or foxfire burst out with a bang.

　And then it dropped a blue - or rather green oval fruit.

''A lemon?''

　I mumbled, moving closer and picking it up.
　The smell wasn't a lemon.
　It was a thick smelling fruit, so thick that you could tell just by picking it up that it was sweet and sour.

　The skin on the surface was smooth and smooth, obviously different from the lemony, citrusy, mousy rind of the fruit.

　To the touch, that skin was about the size of a thick grape.
　The flesh, like the flesh inside, feels completely different, the kind of skin you can peel off with your hands, not a blade.

　So I peeled the skin off with my hand.
　What came out of it was an orange flesh.

'Is this a ...... mango?'

　The flesh inside was familiar. I knew what it smelled like.

　When I took a bite - the sourness prevailed, but it tasted like a mango I'd had before.

　I wondered if it wasn't fully ripe or if it was that kind of variety that looked green.

'I didn't know there was such a thing as a mango.

　And since Nihonium had been all about sweet and sour fruits so far, the taste of this mango immediately made sense to me.

　It was a waste, so I flattened it and then walked around the dungeon.
　It's still sour on my drop S, so maybe it's that kind of variety.

　With that in mind, I take down the encumbered monsters.

　Specters in the form of flames floating in the air that follow and disappear.
　The only thing that follows and disappears is its appearance, not its existence itself.

　To prove it, if you use tracking bullets, the tracking bullets will chase it, defeat it, and make it drop a blue mango, even if it is following you or disappearing.

　I wondered if it would be tougher if you're an adventurer who relies heavily on sight, and I was analyzing it.

　The fireball I encountered swooped in and disappeared.
　As soon as I raised my gun, to my surprise, the entire dungeon went dark!

Mmm.

　It's so dark that you can't help but speak up.

　You bring your hand in front of your face, but you can't see that it's there.

　It's like every light has gone out, and you're enveloped in such darkness.

...... mirror?

　I mumbled reflexively, having been convinced that the three divine weapons would be the key items, and I've been prepping for them.
