Man, the 3rd still could've regenerated after taking on Tanjirou and Giyuu ... the 2nd didn't seem to have any humanity/empathy in him and 1st is no joke. It'll be tough for whoever's facing them.
@duylinh if memory serves me right, didnt the first season end anti-climactic, with Latifa recovering from the disease at the end of the first goal? Would it be hard to pick up where the original source intended?
Never read the LN so not sure how true to source the anime was.
