Demon Slayer Watch Order 2026: Mugen Train to Infinity Castle
If you want to watch Demon Slayer in order in 2026, the path is short and almost entirely spoiler-safe: four TV seasons, one film that doubles as a TV arc, and a new movie trilogy that finishes the story. This guide lays out every step, the episode counts, and exactly where each part streams today.
Demon Slayer (Kimetsu no Yaiba) tells one continuous story, so release order and chronological order are the same. There are no timeline jumps to plan around and, unusually for a long-running shonen, essentially no filler. Start at episode 1 and keep going.

Season 1: Unwavering Resolve Arc (26 episodes)
This is where everyone starts. Season 1 covers 26 episodes from 2019 and follows Tanjiro Kamado after his family is slaughtered and his sister Nezuko is turned into a demon. It carries you from his training through the Mount Natagumo spider arc.
Season 1 sets up every rule of the world: Breathing styles, the Demon Slayer Corps, and the Twelve Kizuki who serve the demon king Muzan. Nothing here is optional, and it is the strongest possible entry point for a new viewer.
Mugen Train: the movie vs. the 7-episode TV arc
Mugen Train is the one spot where people get stuck, because the same story exists in two formats. You only need one of them.
- The 2020 film — the original theatrical cut, and still the most cinematic way to experience it.
- The TV arc (episodes 27–33) — the same story recut into seven episodes, plus an extra prologue episode that follows the Flame Hashira Kyojuro Rengoku before the mission.
Watch the film for the theatrical version, or the TV arc if you want the added Rengoku prologue. Either way, Mugen Train is essential to the plot — do not skip it. Rengoku's story matters directly to the Infinity Castle finale, and he remains one of the most collected characters in the series.
Season 2: Entertainment District Arc (episodes 34–44)
After Mugen Train, Season 2 runs 11 episodes covering the Entertainment District Arc. Tanjiro, Zenitsu, and Inosuke join the Sound Hashira Tengen Uzui undercover in Yoshiwara to hunt an Upper Moon demon.
This arc is where the animation studio Ufotable's reputation for spectacle became impossible to ignore, and it introduces the stakes of fighting an Upper Rank demon head-on for the first time since Mugen Train.
Season 3: Swordsmith Village Arc (episodes 45–55)
Season 3 is another 11 episodes, set in the hidden Swordsmith Village. Tanjiro meets the Mist Hashira Muichiro Tokito and the Love Hashira Mitsuri Kanroji while two more Upper Moon demons attack.
The arc also advances the mystery of the scarlet crimson sword and Nezuko's growing resistance to sunlight — a plot thread that pays off directly at the end of the season and pushes the story toward its final confrontation.
Season 4: Hashira Training Arc (episodes 56–63)
Season 4, which aired in 2024, is the shortest TV season at 8 episodes. It is largely a bridge: the Hashira put the corps through brutal training while Muzan closes in on their leader, Kagaya Ubuyashiki.
The final episode of Season 4 leads directly into the Infinity Castle. If you are watching in 2026, treat Season 4 as the on-ramp to the movie trilogy rather than a self-contained season.
Infinity Castle: the final arc as a movie trilogy
The Infinity Castle Arc — the manga's finale — is not a Season 5. It is being adapted as three theatrical films that pick up the instant Season 4 ends, when Muzan drags the entire Demon Slayer Corps into his shifting fortress.
Where to watch Infinity Castle Part 1 (streaming July 28, 2026)
Infinity Castle Part 1 opened in Japan on July 18, 2025 and in the United States on September 12, 2025. It runs 155 minutes and grossed $793.5 million worldwide, becoming the highest-grossing anime film ever released in the US.
For streaming, it began its first subscription run on Crunchyroll worldwide on July 28, 2026, with the original Japanese audio, English subtitles, and the English dub that played in US theaters. Netflix carries the same film across Asia on that date, excluding Japan, Mainland China, and India.
When do Parts 2 and 3 arrive?
As of September 2026, neither Part 2 nor Part 3 has an official release date. Reporting points to 2027 at the earliest for the second film. Because Part 1 ends mid-story, there is no way to "finish" Demon Slayer yet — the trilogy is the ending, and it is still in progress.
Do you need the compilation films?
Between seasons, Ufotable released two theatrical compilation films: To the Swordsmith Village and To the Hashira Training. Each recaps the previous arc and tacks on the first episode of the upcoming season.
If you are watching the TV seasons in order, you can skip both. They exist for theatergoers who wanted a recap plus an early look, and they add no new story beyond the season premiere they preview.
Is Demon Slayer worth watching in order? (release vs. chronological)
Yes — and there is only one order to worry about. Demon Slayer runs as a single unbroken timeline, so its release order and chronological order are identical. Unlike franchises with prequels and side stories, you never have to choose between two viewing paths.
The only real decision is the Mugen Train format (film or TV arc), and the only truly optional content is the two recap compilation films. Everything else is watched in the order it aired.
FAQ: Demon Slayer watch order questions
Do I have to watch Mugen Train?
Yes. Mugen Train is core plot, not a side story. Watch either the 2020 film or the TV arc (episodes 27–33) — they tell the same story, so you only need one.
Is there any filler in Demon Slayer?
Essentially none. The anime follows the manga closely with no standalone filler arcs, which is why the total runtime is short for a series this popular. You can watch everything without skipping episodes.
Where can I watch Infinity Castle Part 1?
Crunchyroll streams it worldwide as of July 28, 2026, and Netflix carries it across Asia (except Japan, Mainland China, and India). It is also available to rent or buy on services such as Prime Video and Apple TV in some regions.
Do I need to watch Infinity Castle before Season 4?
No — it is the reverse. Watch Season 4 first; Infinity Castle Part 1 begins exactly where Season 4's finale stops. For a deeper breakdown of the film's release and streaming timeline, see our Infinity Castle streaming guide.
What to collect while you catch up
The gap between Infinity Castle films is long, and collectors are using it to build out their shelves. The most chased pieces right now are Rengoku, the Hashira, and the Upper Moon demons who drive the finale.
If the trilogy has you wanting Demon Slayer figures, Akibato ships them from Japan — browse the Demon Slayer collection for scale figures, prize figures, and the current Ichiban Kuji stock. New here?

- All four TV seasons plus Infinity Castle Part 1 stream on Crunchyroll; Netflix carries the film across most of Asia.
- Infinity Castle Part 2 has no confirmed date yet (2027 at the earliest), so the story is not finished.
