How many seasons does Demon Slayer have?

A friend told you about Demon Slayer, you start the first episode on a Sunday evening, and three hours later you are looking up how many are left. The question comes up for everyone who starts the series, and the platforms do not help: one shows four seasons, another five, and the films slot in between.

Here is the exact count, season by season, with the dates, the number of episodes and the manga arc adapted, then where the films fit and what is still to come. The precise order to watch everything is on our page Demon Slayer in what order, seasons and films.

How many seasons does Demon Slayer have?

The TV series has four seasons and 63 episodes, all produced by the studio ufotable. Each season adapts one or two arcs of the manga, in story order.

The seasons get shorter as the story goes on, but the episodes get longer. Season 3 opens with a one-hour special episode and ends with a 70-minute episode: real short films broadcast on television.

If you are discovering the series, know that the pace picks up sharply on Mount Natagumo, from episode 15 of season 1: that is often where hesitant viewers become fans.

Why does Netflix show five seasons?

Netflix France presents Demon Slayer in five seasons, and it is not a mistake. The platform puts the seven Mugen Train episodes, aired in autumn 2021, in a season of their own, while Japan counts them as the start of season 2.

The same arc exists as a film, released in Japan on 16 October 2020. The series version takes up the film’s story and adds a brand-new episode, devoted to Rengoku before his mission: you can choose one or the other, there is no need to see both. Our article on the Mugen Train, as a film or a series helps you decide.

Depending on the platform, you will therefore see three ways of splitting it. Netflix numbers five seasons. Japanese sites talk about arcs rather than seasons: the Final Selection arc, the Mugen Train arc, the Entertainment District arc, the Swordsmith Village arc and the Hashira Training arc. And most fans in France talk about four seasons, like this guide. Our article on the platforms where you can watch Demon Slayer sets out what each one offers.

A tip to find your way: go by the arc titles rather than the numbers. Whatever the service, the order stays the same, from the Final Selection to the Hashira Training, and each arc starts where the previous one stops.

Rengoku, the hero of this arc, has his large tapestry, which takes up the whole train scene on a bedroom wall; it is filed in the wall tapestries collection, next to the character posters.

The four seasons, one by one

Each season has its colour, its big villain and its star Hashira. Here is what awaits you, without revealing the endings.

Season 1 sets up the whole universe. Tanjiro Kamado loses his family, sees his sister Nezuko become a demon, trains for two years on Mount Sagiri and joins the Demon Slayer Corps. It peaks on Mount Natagumo, where Rui’s spider family pushes him to his limits. Our article on Demon Slayer season 1 tells it arc by arc.

Its 26 episodes leave time to get attached. You meet Zenitsu, who screams with fear before every fight, Inosuke and his boar’s head, then the Hashira, gathered in the last episodes to judge Tanjiro. Episode 19, in which Tanjiro rediscovers his father’s dance facing Rui, remains one of the most famous in the whole anime: it is the one fans show their friends to win them over. Our page everything about Tanjiro Kamado traces the hero’s journey.

Season 2 links two arcs. The Mugen Train features Rengoku, the Flame Hashira, facing Enmu then Akaza. The Entertainment District sends the trio to Yoshiwara with Tengen Uzui, the Sound Hashira, against Daki and Gyutaro. Our article on season 2 and the Entertainment District details this second half, and the portrait of Tengen Uzui, the Sound Hashira presents its hero.

The Entertainment District is often cited as the most beautiful season to watch. The lantern-lit streets of Yoshiwara, Daki’s sashes slicing through the rooftops and the final fight, spread over several episodes, set the bar very high for all Japanese animation of the time.

Tengen also comes as a figure, gem headband on his forehead, in the complete Tengen Uzui collection.

Seasons 3 and 4, before the final battle

Season 3 takes place in the hidden Swordsmith Village. There, Tanjiro meets Muichiro Tokito, the Mist Hashira, and Mitsuri Kanroji, the Love Hashira, while two Upper Moons attack the village. It is the season in which Nezuko crosses a decisive threshold. Our article on season 3 and the Swordsmith Village tells it, and our portrait of Muichiro Tokito, the Mist Hashira presents the young prodigy.

Its eleven episodes alternate two fights in parallel, Muichiro’s against Gyokko and Tanjiro, Nezuko, Genya and Mitsuri’s against Hantengu and his clones. It is also the season that reveals Muichiro’s past, one of the most moving moments of the series.

Season 4 changes tone. No big fight for seven episodes: the Hashira train the demon slayers in turn, between exhausting exercises and funny moments. The eighth episode, for its part, opens the final war. Our article on season 4 and the Hashira Training details it, and the one on the Hashira Training, station by station follows Tanjiro from master to master.

Muichiro, the hero of season 3, draws his sword in a swirl of mist on his 25 cm figure, presented in the complete Muichiro Tokito collection.

Which season is the best?

Every fan has their favourite season, and the answer depends on what you are looking for. Here is what each one does best.

If you are hesitating to continue after season 1, at least watch the Mugen Train: it is the arc that turned the series into a worldwide phenomenon, and Rengoku’s death made entire cinemas cry in 2020. Our portrait of Kyojuro Rengoku, the Flame Hashira explains why this character left such a mark, and our page on the nine Hashira of the Demon Slayer Corps presents the heroes of each season.

Season 4 divides opinion more. Those who love fights find it slow, those who love the characters see it as the most endearing: it is the only one where the Hashira laugh, eat and train together. Above all, it prepares the Infinity Castle, where each of these bonds will matter.

And where do the films fit in?

The films slot in between the seasons. There are three kinds, and only one is essential to the story, depending on the version of the Mugen Train you choose.

The compilation films contain nothing new for anyone following the series. Our article on the Demon Slayer compilation films explains what they take up, and the one on the first Infinity Castle film what it tells.

Will there be a season 5?

No, not in the form of a season. The end of the story, the Infinity Castle arc, has 44 chapters of almost non-stop fighting, and the studio chose to adapt it as three films rather than as a series.

As of 21 September 2026, no date has been announced for the second film. A Sony Pictures listing published in September 2026 mentions a US release on 17 September 2027 for an untitled Crunchyroll film, which the specialist press links to the sequel, but neither the studio nor Crunchyroll has confirmed it. Our article on the Infinity Castle sequel is updated with every announcement.

There is still a lot to tell. The first film stops after the fight against Akaza, around chapter 157 of the manga. The next two will have to cover the end of the Castle, with the fights against Doma and Kokushibo, then the whole final night against Muzan, around sixty chapters in all. Fans who have read the manga know that the best moments are still to come on screen.

In the meantime, the manga tells everything, up to the last chapter. If you cannot wait any longer, our article on the chapter to pick up from after the anime gives you the exact page, and our page on the manga and its 23 volumes gives the rest.

How long does it take to watch everything?

The 63 episodes add up to about 25 hours, special episodes included. Add the Mugen Train film if you prefer it to the series version, nearly two hours, and Infinity Castle, about two and a half hours: allow around thirty hours in total.

If you want to save time, do not skip any season: each one prepares the next, and the films assume you have seen everything. The only optional parts are the compilation films, which take up existing episodes.

At two or three episodes a night, the series is finished in a month. Those in a hurry get through it in a few weekends, and many fans rewatch it before each new film. If you are watching with a child, our article on the recommended age for Demon Slayer lists the episodes worth watching together.

Also choose the language before you start: all the seasons are available with a French dub and in the subtitled original. Our article on Demon Slayer, French dub or subtitled original compares the two. The characters you are going to meet are all presented on our page listing all the Demon Slayer characters.
