That title does not literally mean Slime x Hunter for those kinds of people who expected it to be some ship of a slime and a hunter.
Rimuru woke up, something did not feel right. He scratched his head and found a piece if paper in front of him. "My bad Top G," the paper read, "I changed a couple things here, again my bad Top G. Anyway, on topic, I'm editing your world's storyline, but I'll make sure you somehow forget about it once you finish reading this. I loaded your brain with the basic knowledge of this world. And a few other things as I've said. But you'll find that soon enough. GTG Top G!" And the paper poofed, with a Rimuru Tempest forgetting the "editing your world's storyline" part.
Now obviously, credits belong to their original creators, and is made because I got motivation from Hunter x Slime because it seemed like a cool idea.
Also, this story's plot is basically improvised, except the first 3 chapters where I base it off the plot of HXH. But in later chapters the plot will slowly, but surely be closely related to HXH, except with Rimuru being actually acomplishing some stuff here rather than be a background character.
Recommended to read on mobile! But not mandatory.
Now enjoy the story and let's see if I can actually make a full blown story.
