Fantastic series! One of the best and unique animations I've seen as of recent. I love the breathing techniques and the individual characters. Tanjiro's journey into avenging his family and find a cure for his sister Nezuko who has turned into a demon.
His companions along the way that go through Demon Slayer training have specialized techniques that bring something different in the form of breathing style.
It's crazy how there are 12 main demons that the Demon Slayers have to conquer in order to get to the final boss Muzan Kibutsuji. I hope to be watching this show for years to come since they are barely scratching the surface of the overall storyline.
Oh and the opening and ending songs are godlike!
