> Demon Slayer

yes.

don't know if OP is referring specifically to some anime or anime in general but the 3 of the top 5 grossing films in japan are animes and animation is a fully developed medium for story telling of all ages.

if native japanese don't know about kimetsu i guess it's the same way my parents have definitely not watched a single marvel film, and i'm not sure if they are even aware of their existence.
