Episode 1: Where Are We?

In the final fight between both dimensions, Izuku and Tanjiro were fighting their arch-enemies, Tomura Shigaraki and Muzan Kibutsuji. As the battles continue, they are hit by two bright lights and now they have been isekaid to a Fantasy World. How would our Heroes and Slayers survive and adapt to this new world? And who will they face against those they are not familiar with? Found out when you read this story.

(I'm making it easy for myself by only focusing on My Hero Academia, Demon Slayer, Tensura, and So I'm a Spider so what? Also, some of my old waiting will also be in this store so some of my writing are the same.)
