(Y/N) is a half demon. Her mother was turned into a demon while pregnant and still miraculously gave birth to (Y/N).

Just a small giyuu x reader since I'm in quarantine and v bored. Lowkey a shitty description that doesn't describe the book well now that I reread it but just read and y'all will find out lmao Copy right: I do not own demon slayer or any of the characters

After Zeus The Lighting God died the Gods only had only one thing to do and that was take Zeus's soul and Reincarnate him into an new baby and that baby was Y/n. Y/n grew up with Nothing but One day he met Rias that day an that changed his whole life but it was not what he seems. Also I don't own any art that I use or Highschool DxD
