A/N
Hi, it's author-san here. First fanfic and this idea has been on mind for a while.
Warning: SPOILERS AHEAD FOR ANIME, MANGA AND LIGHT NOVEL
Also, I don't own any characters or worlds here. The only thing belonging to me is the plot, everything else belongs to their respective authors.
There may be some things that don't make sense, like location. Don't even ask me how to merge all the fictional worlds I included into one.
There will also be lots of plot holes. I'll try my best to cover them but I can't guarantee I will for all of them.
Also although Rimuru doesn't have a physical gender I will refer to him as HE.
My rule is basically one verse doesn't interfere with the other at all. For example, when Sukuna in jjk wiped out Shinjuku, characters from one punch man aren't going to interfere at all.
Some characters from different verses may meet but there won't be anything too deep with it.
There may also be some timeline changes in the story.
I will also make some skills up for Rimuru and basically make everything more understandable.
Also, this is written in the future, but reading back to the earlier chapters, I can definitely feel my writing is a bit rushed. I just ask for you to bare with me for a while here until maybe the later chapters.
Hope you like it <3
