Anime fan for 15 years. Covers shonen, seasonal previews, and the occasional deep dive.
Demon Slayer is one of the most visually stunning anime ever made, but its release format — mixing TV seasons with theatrical films — creates genuine confusion about watch order. Where does Mugen Train go? Is it the movie or the TV version? What about Infinity Castle?
Here's the clear, simple answer.
The quick answer
Watch in this order: Season 1 → Mugen Train Arc (TV version OR movie) → Entertainment District Arc → Swordsmith Village Arc → Hashira Training Arc → Infinity Castle (movies). That's it. Demon Slayer has zero filler.

Mugen Train: movie or TV version?
The Mugen Train movie (2020) became the highest-grossing anime film in Japanese history. When Season 2 aired, the first 7 episodes were a TV adaptation of the same story with additional scenes.
Watch the TV version if: You want a consistent viewing experience and don't mind slightly less cinematic quality.
Watch the movie if: You want the best animation quality and the theatrical experience Ufotable intended.
Both cover the same story. Do NOT watch both unless you want to see the same events twice. The TV version's Episode 1 is anime-original and provides nice context, but episodes 2–7 are essentially the movie recut into episodes.
Where to watch Demon Slayer
- Crunchyroll — All seasons (subbed and dubbed)
