Theory(MHA & KNY)

This is not meant to be played, I just want to share a theory I made up. ————————————————————— So, Demon Slayer (KNY) is set in the Taisho Era (1912-1926) and My Hero Academia (BNHA) is set in the early to mid 2170s. Obviously quirks exist, but how? Theres lots of theorys but mine is that after everyone died in Demon Slayer, Yuishiro got lonely and made another demon, and since Yuishiro wasn't created by Muzan directly he didn't have Muzan's blood. That means that when Yuishiro created the demon his blood behaved differently, possibly causing a human with demon-like abilities, a quirk. ————————————————————— So in summary, after everyone died in Demon Slayer Yuishiro got lonely and made a demon, but his blood behaved differently than Muzan's therefore creating a human with demon-like abilities, which later became known as a quirk. ————————————————————— I hope you liked reading my theory and have a good morning/day/night! Bye!
