After defeating the Grand Eater, I slumped down and sat there.
　Somehow I managed to defeat ...... maybe the most powerful enemy I've ever had.
　That's how cornered I was.

'......'

　...... No.
　You don't have ...... to take it down, do you?

　Look around.
　The basement level of the Nifonium Dungeon, near the exit.

　There's an exit in front of you, and you can see the view outside.
　If you turn around, you'll see the familiar dungeon, crawling with skeletons you've seen more than your parents' faces.

　But there's nothing.
　A drop, no.

　My own unique skill, drop S.
　In a world where everything drops from dungeons, the Drop S is the most powerful skill to make any monster drop.

　You can't drop Nifongnium monsters or Hagremonts that humans can't drop in this world.
　As long as you defeat them, they will drop.

　That didn't happen.
　Because I didn't beat them.

　Technically, I just got away with it.
　I used this world's immovable logic well to lead them out of the dungeon and make them disappear.
　I didn't defeat him.

　That's why I didn't drop it.

　It was the first time I didn't drop it.
　I was the first one who didn't drop no matter what I defeated, and I was the first one who didn't drop it.

.............

　A little ...... No, quite.
　That's pretty frustrating.

　I wish I hadn't noticed, but when I did, it was like a fish bone stuck in the back of my throat.
　It really bothered me and I had to remove it.
　It's that uncomfortable.

　That's when I wondered what I should do: ......
　That woman, that doll-sized, translucent woman in a kimono, appeared again.

　She bowed to me, which I already identified as a Nifongnium in my mind.
　It was a bow with an elegant gesture, just like the way she was dressed.

　Thank you, I felt as if she had said that to me, though it was silent.

'Don't worry, I don't want to lose it here either.
......

　Nifonium returned the kibble and started walking.
　He walked with such grace that he was a good example of good manners in a manners class.

　He walked a bit, stopped, turned around and looked at me.

'Do you mean to tell me to follow you ......?'

　When I asked, Nihonium started to walk further.
　I didn't know what she was talking about, but I followed her.

'So you're a Nifonium after all,'
......?

　She just turned her head and tilted it back, with me leading her.

'No, it's not right to tilt, anyone can see that when they see something like this.

　I pointed to the side.
　Nifonium basement level two, a level where the zombies swarmed.

　Normally, the zombies would be grunting and attacking me, but I didn't have any of that.
　The zombies made way for her, hands on their knees, heads down.

'It's some gangster, or maybe it's just a whole lot of polar wives.
......

　Nihonium just smiled and didn't answer.

　He was led away as it was.
　On the third, fourth, and fifth underground floors, the undead monsters bowed to Nihonium and yielded their way.

　Then Nihonium stopped at the back of the fifth basement floor.
　Beside it, there is a stone wall.
　She stared at it and turned to me.

'Ah, there's another one.'

　They nod.
　I knew it was a nihonium ...... the spirit of this dungeon.

　It looks like just a stone, but the Grand Eater's stone is foreign to this dungeon.
　Just like Aulum can detect an adventurer hunt, so can Nihonium detect this.

　I stared at the stone.
　The stone that hatches in the Grand Eater - the stone that the Grand Eater dropped.

　The stone I couldn't let ...... drop.

　I stared at it and sat down with a thud in front of it.

　Thinking.
　Remove the fish bone stuck in the back of my throat.
　I thought of a way to do it.

　...... Ask Celeste and she'll tell you.
　They're mass-produced enough to be used in a conspiracy, so there's probably an established way to take down a Grand Eater, but I decided to figure it out for myself.

　I stare at the stone and remember the fight I just had.
　It's a battle that made me lick the bitterness out of my body, which could be considered a complete defeat, but I thought about whether or not I could grab something from it.

　It's a pattern in a way.
　The Grand Eater erased everything like an eraser.

　It's kind of like an extinguishing bullet, only erasing what it touches.

'You're invincible: ......'

　You can erase magic as well as matter, so you would be unquestionably invincible.
　You want to use something that can't be erased to defeat it?　Then you'll be out of luck. ......

...... hmm?

　I'm stuck.
　I'm stuck for a second.

　I'm stuck on what?　I am.

　I can go back through my thoughts, trace what I think.
　I can erase everything, erase it like an eraser.

　The Grand Eater makes everything disappear with a single touch.

"Erase?

　Wait, do you want me to turn it off?
　Grand Eater, aka Dungeon Eater.

　Eater, not Eraser, Eater.

　They say a name represents a body.
　Either your real name or an alias.
　He was both an eater.

　He's not erasing it, he's eating it.

"Eater." ......

　I stared at the stone in front of me.

　　　　　Stars

　Outside the dungeon in Nifonium, right by the entrance.
　I put a stone there and kept my distance.

　It's shameful, but it's an insurance policy.
　If it didn't work, it was an insurance policy to guide me back in with the scrap bullets to eliminate them.

　Hopefully, my guess is right.
　I waited for it to hatch.

　After a while, the air changed.
　The air of a dungeon master drifted around.

　The stone hatched into a grand eater.

　I held up my gun.
　He loaded the remaining gun with only two types of bullets.

　Lightning rounds and recovery rounds.
　Two types of bullets that were infinite after attacking the dungeon.

　Infinite lightning bullets were shot, not hit, slightly to the right of the Grand Eater.
　The Grand Eater reacted, waved his arm and ate the lightning bullets (...).

　Then I fire a recovery round, also don't hit it, but shoot it slightly to the left of the Grand Eater.
　He reacted in the same way, waved his arm and ate a recovery round.

　Thunderballs, recovery bullets, thunderballs, recovery bullets.
　An infinite number of bullets were shot in turn.

　In a way, it's the same as with the scrap bullets.
　He swung the bullets left and right and swung the Grand Eater around.

　It's like a repetitive flying grand eater, and it eats the bullets.

　I keep firing.
　10 rounds, 20 rounds, 50...... 100.......

　I shot left and right, taking advantage of the fact that it was infinite.

　The Grand Eater's body, which continued to eat bullets, was clearly larger. It was one - or even two - larger than the first.
　It was so big that it was impossible to mistake it for anything else.

　Grand Eater, not Eraser, Eater.

　If you're eating it, there's a limit.
　Even an Eraser might have limits, but an Eater should have more limits.
　So I thought, I kept feeding it endless bullets, and this is how it worked.

　I could do it, I thought, and I picked up the pace.
　No longer swinging from side to side, I fired a series of infinite lightning bullets and infinite recovery bullets.

　The Grand Eater's body was growing in size at an accelerated rate.

''Can you really go ......?''

　The pace of that guy's eating didn't slow down to the point that I couldn't help but feel uneasy.
　No matter how many bullets you shoot at it, it will devour it with a flick of its arm without a problem.

......

　I shook off my hesitation and continued firing in rapid succession.
　Trusting myself, I kept firing bullets at the Grand Eater, which had swelled up to about ten times its initial size, the result.

　Pshhhh .......

　I heard a sound of air loss.
　A part of the swollen Grand Eater's body burst open and immediately afterwards, it rapidly squeezed out.

　The Grand Eater kept swinging its arms while it was out of the air and tried to attack me, but the pace of its exit was even faster than that, and soon it was smaller than the first time, and then it was gone.

　The amount of bullets that exceeded the limit - roughly four digits of bullets fed to me, the Grand Eater disappeared.
　Where it stood, it dropped a shining stone.

'...... Okay.'

　He gave a small gut-punch with his free hand while holding the gun at the ready.
