Hey I have an idea for a crossover fic
Between demon slayer and mha
Start at when muzan turned tanjiro into
A demon and he break out of craze to late
Because he already killed everyone he loved.
Then he isolated himself by going inside
Of a cave for 500 years (since bnha set in
2400s. I Google that)(and kny is set in 1912)
And then a group of villain rediscovered the cave(since he destroyed the entrance when came in)
Or Alternatively
A group of archaeologist rediscovered the cave
