To be honest, I hadn't have been interested in this comic until recently but I gave it a try since I had some time.
It was like almost immediately I got into this and caught all the story up. This story is exciting, heartwarming, and fantastic!
Now I understand why many people love this comic.
The movie is a part of the comic story where one of the Hashira was called to check a train that many passengers have been gone somehow and it is probably because of a demon.
Tanjiro and the other two joined him to conquest the demon.
I cry whenever I see this story and it is worth checking out.
If you haven't seen the comic at all, I recommend checking it out!
