@Khang Ngọc Chung Nguyễn don't give spoilers dude some people HAVE'NT read the manga, and by obviously canon I meant in the first season we are not sure about tanjiro but we are very sure for kanao when her older sister said she would open her heart with love, when tanjiro flipped the coin and made her promise she would follow her heart and ran away, in that scene there was a close up and wind effect with the sparkles in her eye
Yeah i think they died but they got reincarnated in the modern world, as u can see by their clothing, but they basically forgot everything, they dont even remember that there is a demon long ago
