A SPIDER IN A HERO SOCIETY |Rui Ayaki x Mha|

What happens when a character from another dimension enters the world of MHA? Specifically, a little spider demon from Demon Slayer, also known as KNY or Kimetsu No Yaiba. Will he become a villain? A hero? Hell, even a vigilante? Who knows!
Characters are not mine.
MHA or KNY is not owned by me.
The only thing that I own is this book.

I'm probably going to be very unmotivated and might not post chapters for a long time.
