What if Tanjiro Became a Demon in Episode 1?

What if Tanjiro turned into a demon in Demon Slayer? Welllll let's just say the ENTIRE demon slayer story would change. (and not in a good way). I cover shonen anime like Black Clover, My Hero Academia, Attack on Titan, Demon Slayer, and One Punch Man. #IMOTO #anime #demonslayer
