The Self-Cultivation of the Moe King in a Crossover World!

My earliest memory was of being a slime. I can't remember anything from before that.

I don't know who I am or what I went through, but I know all sorts of strange things, and I know that I've been reincarnated many times.

As a proper slime, after someone named me Rimuru, I diligently put the knowledge in my memories to use.

Save my best friend, establish a nation, subjugate demons, become a Demon Lord after falling to darkness, and then save the world.

But after saving the world and becoming the strongest, I messed up. I really messed up!!

After that, I transmigrated, except...

A certain enemy, a Port Mafia executive: "I've finally seen you again. That's all that matters. As long as you're happy."

A certain great yokai from the West: "Are you here? My wife?"

A certain Shinigami: "Reincarnated? How surprising."

A certain black-faced great onmyoji: "How interesting. I wonder if I can put your power to use."

A group of great yokai: "We've finally found you, Master."

Rimuru: "...Panic. Did I transmigrate the wrong way, or did I transmigrate in the wrong position?!"

"Have you got the wrong person? I'm just an ordinary slime!"

#What on earth happened? #

#Don't all come over here!#

#Why does it seem like the whole world knows me?!#

This idea came to me out of nowhere, so I wrote it down.

Everyone has a one-sided crush on the protagonist.

My writing is terrible and the logic is dead. Please bear with me.
