ancestors [hero student user] [All characters are 18+]

This is an AU where both animes are sent in the same universe but at different times and MHA characters are the descendants/reincarnations of the slayers/Hashira.

Also I am fully aware that My Hero Academia is technically set in the future however for this au it's going to be set in modern day so there's about five or six generations between the Demon Slayer characters and the MHA characters so say your OC is the descendant of one of the Hashiras that person would be your OC's 3rd-great-grandfather/Mother.

Everyone is alive so you can choose who dies and who doesn't. So far in the personality section I have all of class 1-A, Aizawa, all the Hashira, and the Kamaboko Squad but if you want me to add anyone else just ask in the comments and I'll do it when I can.

I also have a Hashira User version.
