Frequently Asked Questions
Should I watch the Mugen Train Movie or the TV Episodes?
We highly recommend the TV Episodes. While the movie is a cinematic masterpiece, the 7-episode TV arc includes a completely original first episode showing how Rengoku made his way to the train. The subsequent episodes take the exact movie footage and add new music, slight touch-ups, and proper episodic pacing.
Are there any filler episodes in Demon Slayer?
No, there are no traditional “filler” arcs. The only episode considered an “anime original” is Episode 1 of the Mugen Train TV arc, but it is heavily approved by the creator and considered canon to the anime timeline. Everything else is directly adapted from the manga.
What comes after the Hashira Training Arc?
The story will conclude with the Infinity Castle Arc. Instead of being adapted as a standard television season, Studio Ufotable has officially announced that the grand finale will be adapted into a trilogy of high-budget theatrical movies.
