[User: MilimBestGirl]: wait wait wait.
hold on.
is this BEFORE rimuru arrives in the world?
like, this is a prequel?
a woman finds veldora first?
[User: SlimeFan_442]: bro.
BRO.
imagine if rimuru arrived RIGHT NOW.
like, right at this moment.
he spawns in the cave and there’s a naked woman on the floor.
LMAOOO
[User: TempestKingdom]: …this would basically be a smut novel.
you know that, right?
[User: DragonSimp_99]: don’t tell me…
is this before rimuru arrived in this world???
[User: SlimeFan_442]: YES!
imagine what would have happened if rimuru the slime arrived before this woman died.
or maybe right now.
he’d see a naked woman in the cave lol.
it would have become a smut novel.
The writer — the author, the creator, the sweaty man at his keyboard — grinned.
He leaned forward, fingers hovering over the keys.
“Yeah,” he muttered to himself, typing as he spoke.
“Yeah, this would have been better than the original.”
He posted the reply: ‘Yeah, this would’ve been better than the original.
Imagine Rimuru spawning right next to her.
The system evolving him based on his first contact with a human body.
A SEX SLIME.
LMAO.’
He hit send.
Leaned back.
Laughed at his own joke.
Then a window popped up.
Not on his screen.
In the air.
Directly in front of his face, hovering at eye level, a translucent blue rectangle of light materialized from nothing — no hologram, no projection, no explanation.
It simply existed, floating in the space between his nose and his monitor, and on its surface, in clean white text, were the words:
「Do you truly think that?」
He blinked.
He rubbed his eyes.
The window remained.
“What the—”
He reached out.
His hand passed through the rectangle of light — it was not solid, not tangible, but it was there.
Real.
Present.
Impossible.
“What is happening?” His voice came out as a croak.
“Is this — is this a prank?
Some kind of AR thing?
Did someone hack my—”
「Do you truly believe your version would be superior to the original?」
The text changed.
The window pulsed with soft light.
He stared at it.
His heart was hammering.
His palms were sweating.
This was not normal.
This was not something that happened to people in one-room studios at two in the morning.
“Prove it,” he said, and his voice was barely a whisper.
“If you’re — if this is real — prove it.”
「As you wish.」
The window flared.
The light expanded — not outward but inward, folding into itself, collapsing into a point of blinding brilliance that hung in the air for one agonizing, beautiful second.
Then the light took him.
He did not scream.
He did not have time.
The apartment was empty.
The computer screen glowed.
The forum thread sat open, the cursor blinking in the comment box, waiting for a reply that would never come.
## Rebirth
I opened my eyes.
No.
That was not quite right.
I became aware.
There was a difference — a vast, fundamental difference between the act of opening eyes and the act of simply…
becoming aware that one existed.
I had no eyes to open.
No eyelids.
No face.
No body that I recognized as a body.
Where am I?
The thought echoed through me — through whatever I was now — and it was the first thought I had, and it was the same first thought that every reincarnated soul has had since the beginning of time, and I hated myself for how unoriginal it was.
Dark.
It was dark.
But not empty.
I could feel — something.
Pressure, from all sides.
A warmth, a wetness, a softness that surrounded me completely, enveloping me like I had been submerged in something warm and yielding and alive.
I tried to move.
I could move — but not the way I expected.
I had no arms to lift, no legs to extend, no torso to twist.
I simply…
flowed.
Shifted.
My body — my form, whatever it was now — deformed and reformed around the space I occupied, conforming to the shape of whatever contained me.
I was in a tunnel.
No — a passage.
Narrow, tight, warm, and wet, the walls soft and yielding, coated in something slick and slippery that made movement easier but also made me acutely aware of how strange this all was.
I was moving forward, sliding deeper, the passage growing tighter as I progressed, the warmth increasing, the wetness—
A sound reached me.
Not through ears — I had no ears — but through some other sense, some new mode of perception that registered vibrations in the fluid around me and translated them into something my consciousness could interpret.
A pulse.
Slow, steady, faint.
A heartbeat.
Something is very wrong here, I thought.
This is not what reincarnation is supposed to feel like.
This is not a field of flowers.
This is not a void with a god offering me choices.
This is—
The passage opened.
The tight walls gave way to a wider space — still warm, still wet, still impossibly soft, but larger, a chamber of living tissue that pulsed gently around me, contracting and releasing in a slow, rhythmic cycle that matched the heartbeat I had heard.
I was inside something.
Inside something alive.
And then —
「…Analysis complete.
Commencing evolution.」
The voice came from nowhere.
From inside me.
From the structure of whatever I was now.
It was flat, toneless, mechanical, and it arrived in my consciousness like text on a screen, not sound in the air.
What?
Evolution?
What are you—
「Host organism has been analyzed.
Unique biological template detected.
Evolution pathway established.
Acquiring traits based on environmental stimulus and biological contact.」
I did not have time to process this.
The warmth around me intensified.
The walls of the chamber — the living, pulsing, wet-walled chamber I was floating inside — contracted around me, and I felt something happening to my own form.
A change.
A shift at the most fundamental level, the structure of whatever I was altering, reorganizing, adapting to the environment in ways I could not See or understand.
