Jujutsu Kaisen vs Demon Slayer: Which Should You Watch First?

Two teenagers, two secret organisations, two jobs that kill most of the people who take them. Demon Slayer and Jujutsu Kaisen arrived roughly eighteen months apart, run to about the same length, and both get animation budgets most shonen never see. What separates them is how they treat you: one wants you to grieve and keep walking, the other wants you to stop assuming anyone is safe. Every episode count, film and release status below is checked as of September 2026.

What actually exists to watch, as of September 2026

Neither series is finished on screen, which shapes the decision more than any tone comparison does.

Demon Slayer's television run is four seasons and 63 episodes, all from ufotable: the 26-episode original (April to September 2019), an 18-episode second season split between the Mugen Train arc and the Entertainment District arc (October 2021 to February 2022), the 11-episode Swordsmith Village arc (April to June 2023), and the eight-episode Hashira Training arc (May and June 2024). After that the story leaves television. Demon Slayer: Infinity Castle opened in Japan on 18 July 2025 and reached most major territories that September, runs 155 minutes, has taken more than $790 million worldwide, and is the first of a three-film finale.

One trap before you press play: the 2020 Mugen Train film and the seven-episode Mugen Train arc in season two tell the same story. The television version adds a whole new opening episode and a handful of extra scenes, but you only need one of them. Our Demon Slayer watch order sets out the sequence.

Jujutsu Kaisen is three seasons and 59 episodes from MAPPA: 24 across 2020 and 2021, then 23 in 2023 (five for the Hidden Inventory flashback, eighteen for the Shibuya Incident), then 12 from January to March 2026 for The Culling Game: Part 1. There is also a 105-minute prequel film, Jujutsu Kaisen 0, which follows Yuta Okkotsu rather than the usual trio, and a compilation film called Execution that opened in Japan in November 2025 and recuts Shibuya before attaching the first two season-three episodes. Execution is for cinema audiences catching up, not for you; the Jujutsu Kaisen watch order explains where the prequel belongs.

Both leave you mid-story. Season 4, The Culling Game: Part 2, was confirmed as soon as the season three finale aired in March 2026, and MAPPA put out a teaser video that June, but there is still no release date. Infinity Castle parts two and three have no confirmed dates either, whatever the years circulating in press write-ups suggest.

Tone: grief you recover from, or grief that accumulates

Demon Slayer runs on loss converted into kindness. Tanjiro comes home to a slaughtered family and spends the rest of the series proving he can walk through that violence without becoming it. The show extends the same courtesy to almost every demon he kills: a dying flashback that reframes the monster as someone who lost something first. It is sad constantly and genuinely bleak almost never, because Nezuko is always there as the reason the journey is worth making.

Jujutsu Kaisen opens closer to a workplace comedy. Sorcerers bicker about paperwork, teenagers get sent to exorcise a curse behind a vending machine, and the humour is genuinely good. Then it removes the safety net: the Shibuya Incident spends eighteen episodes on a single Halloween night and dismantles everything the first season built.

Spoiler warning: this describes the shape of that arc without naming who survives. Mentors die without redemptive flashbacks, the balance of power collapses, and the strongest character alive is taken off the board, which becomes the premise of everything after it. For that to land you need to have cared about season one first, and caring takes patience the show does not always make easy.

Power systems: forms you can name, or rules you have to learn

This is the cleanest practical difference between them. Breathing Styles are a physical discipline: control your lungs and posture and you get superhuman speed and strength, channelled through an elemental style with numbered forms. Water Breathing has ten. Thunder Breathing has six, and Zenitsu Agatsuma learns exactly one of them, the first, then drills it until it outclasses swordsmen who know all six. You can follow a fight in real time because the show announces what is happening, which is why our guide to every Breathing Style reads as a reference sheet rather than a decoder.

Cursed energy is the opposite design. It leaks out of ordinary people as a by-product of negative emotion, pools where humans suffer, and congeals into curses. Sorcerers are the rare few who can steer it, and almost every one has a different innate technique, so each fight arrives with its own rulebook. Above that sit binding vows, where a sorcerer trades a self-imposed restriction for more power, and the domain expansion, a pocket dimension in which the user's technique cannot miss. Our domain expansion explainer covers how those work, and you will want it.

The upshot: Demon Slayer fights are legible the first time you watch them, while Jujutsu Kaisen fights are arguments won by whoever reads the other's conditions faster. Enjoy that puzzle and Jujutsu Kaisen is the richer show.

The animation question: ufotable against MAPPA

ufotable's signature is compositing: painterly backgrounds, effects that behave like real water and fire, and camera moves that glide through three-dimensional space. The reference point is still episode 19, "Hinokami", from August 2019, where Tanjiro's fight with the demon Rui ends in the Hinokami Kagura reveal. The series trended worldwide afterwards and manga sales climbed sharply, and Infinity Castle is 155 minutes of the same craft without a television budget.

MAPPA's strength is weight and impact. Jujutsu Kaisen favours close-quarters exchanges, hard contact and a camera that stays inside the brawl rather than floating above it, with the Shibuya episodes and the Hidden Inventory flashback as its peaks. Demon Slayer is the more consistently beautiful show; Jujutsu Kaisen has the more thrilling individual sequences.

The casts: one great protagonist, or one great everyone-else

Demon Slayer's lead carries the show. Tanjiro is kind, stubborn and unusually good at reading people, and the series works because you believe in him. Zenitsu and the boar-masked Inosuke handle the comedy, while the Hashira arrive as specialists, dominate a fight and leave. Kyojuro Rengoku shows how well that format works: he carries the Mugen Train arc almost single-handed, and ufotable liked him enough to give the television cut an entirely new first episode following him before he ever boards the train.

Jujutsu Kaisen spreads its appeal differently. Yuji Itadori is likeable but is also the vessel for the series' antagonist, so his best scenes are often the ones where he is losing control of his own body. The gravitational centre is Satoru Gojo, a teacher funnier and stronger than any protagonist, whose presence or absence sets the stakes of every arc. Jujutsu Kaisen has the deeper bench; Demon Slayer has the better central relationship.

How violent is each one, really?

Demon Slayer's family-friendly reputation is largely a merchandising artefact. Common Sense Media puts it at 14 and up, citing decapitation, dismemberment and corpses including children, and the Infinity Castle film is rated R by the MPA in the United States for bloody violence throughout.

Jujutsu Kaisen sits at 15 and up on the same scale, and the gap is texture more than volume. Demon Slayer's violence is swordplay: clean cuts, arterial spray, an opponent who dissolves. Jujutsu Kaisen goes for body horror, with people reshaped and used as raw material by curses that enjoy the work. Demon Slayer is gentler by a small margin, and neither is a children's show.

Where the manga picks up if you catch up

Because both anime stop mid-story, this is the question new fans ask within a week of finishing. Both manga are complete, so nothing you start here will strand you.

Spoiler warning: chapter numbers alone give away roughly how much story is left.

Demon Slayer's television run ends at chapter 139. The Infinity Castle film then adapts chapters 140 to 157, so if you have seen it, open the manga at chapter 158 and read to the finish at chapter 205. Skip the film and chapter 140 is your starting line instead. Jujutsu Kaisen's season three stops at the start of chapter 181, and the story runs to chapter 271, which is roughly a third of the series still unanimated.

Our recommendation, by viewer type

You are	Start with	Why
New to anime entirely	Demon Slayer	Clear quest, self-explaining rules, immediate visual payoff
A lapsed shonen fan	Jujutsu Kaisen	Written for people who already know the genre's habits
Watching with family	Demon Slayer	Still bloody, but built on warmth rather than dread
Here for the fights	Jujutsu Kaisen	Denser choreography, outcomes decided by strategy
Here for the visuals	Demon Slayer	ufotable's consistency across four seasons and two films
Short on patience	Demon Slayer	Arc-per-season structure means fewer slow stretches

The tie-breaker, if you only have time for one: Demon Slayer is the better show to recommend, Jujutsu Kaisen the better one to obsess over afterwards. Finish both and the next step is our list of anime like Demon Slayer, built on the same monster-hunting-corps structure.

Frequently Asked Questions

Should I watch Demon Slayer or Jujutsu Kaisen first?

Demon Slayer first, for most people. Its arcs are self-contained, its Breathing Style power system is explained as it goes, and ufotable's animation makes the appeal obvious within a few episodes. Jujutsu Kaisen hits harder once you already love the genre it subverts.

Which is longer, Demon Slayer or Jujutsu Kaisen?

They are close. As of September 2026 Demon Slayer has 63 television episodes across four seasons plus two films, and Jujutsu Kaisen has 59 episodes across three seasons plus a prequel film and a compilation film. At roughly 23 minutes an episode that is about 24 hours of Demon Slayer and about 23 hours of Jujutsu Kaisen before the movies.

Is Jujutsu Kaisen darker than Demon Slayer?

Yes, though not by as much as its reputation suggests. Common Sense Media rates Jujutsu Kaisen 15+ and Demon Slayer 14+. The gap is emotional: Demon Slayer gives its villains tragic backstories and its heroes a reason to continue, while Jujutsu Kaisen kills characters you love without softening it afterwards.

Do I need to watch both the Mugen Train movie and the Mugen Train television arc?

No. The seven-episode television arc in Demon Slayer season two is a recut of the 2020 film with one new opening episode and some added scenes. Pick whichever format suits you, then continue straight into the Entertainment District arc.

Is Demon Slayer finished?

The manga finished in May 2020 at 205 chapters across 23 volumes. The anime has not. The television series ends with the Hashira Training arc, and the rest is being told as a film trilogy that began with Infinity Castle in 2025. Parts two and three have no confirmed dates as of September 2026.

Is Jujutsu Kaisen finished?

The main manga ended in September 2024 at 271 chapters across 30 volumes, and a three-volume sequel by Gege Akutami called Jujutsu Kaisen Modulo, set 68 years later, ran from September 2025 to March 2026. The anime is not finished: season three adapted the first half of the Culling Game arc in early 2026, and a fourth season covering the second half has been announced with a teaser but no release date as of September 2026.
