Here’s the best chronological order to watch Demon Slayer: Kimetsu no Yaiba so the story flows smoothly from Tanjiro’s first steps to the newest arcs, including movies and seasons.

How to Watch Demon Slayer in Chronological Order

1. Core Watch Order (No Confusion)

Follow this and you’ll experience the story in clean timeline order, without spoilers or backtracking.

  1. Demon Slayer Season 1 – “Unwavering Resolve Arc”
    • Episodes 1–26.
    • Covers Tanjiro’s origin, training, Final Selection, and the early Demon Slayer Corps missions.
  1. Mugen Train – Choose One Version
    You have two options that cover the same story arc:
 * **Option A (Recommended): Mugen Train TV Arc**
   * Season 2 Part 1, Episodes 27–33.
   * Includes an original Episode 27 plus extended/extra scenes.

 * **Option B: Demon Slayer: Mugen Train Movie**
   * The theatrical film retelling the same arc with tighter pacing.

If you want maximum content , watch the Mugen Train TV arc. If you just want the “cinema” experience, watch the movie and skip Episodes 27–33.

  1. Demon Slayer Season 2 Part 2 – “Entertainment District Arc”
    • Episodes 34–44.
    • Follows Tanjiro, Inosuke, and Zenitsu teaming up with Tengen Uzui to face Upper Rank demons in the red‑light district.
  1. Demon Slayer Season 3 – “Swordsmith Village Arc”
    • Episodes 45–55.
    • Focuses on Tanjiro’s visit to the swordsmith village and introduces new Hashira and Upper Rank demons.
  1. Demon Slayer Season 4 – “Hashira Training Arc”
    • Episodes 56–63.
    • Centers on intense training with the Hashira as the final battle approaches.
  1. Infinity Castle Movie Trilogy (Upcoming)
    • Planned trilogy adapting the “Infinity Castle” final battle.
    • Set after the Hashira Training arc, so watch it last when it fully releases.

2. Simple Chronological Checklist

If you just want a quick checklist to tick off in order:

  1. Season 1 (Unwavering Resolve Arc) – Episodes 1–26
  2. Mugen Train
    • EITHER Mugen Train TV Arc (Episodes 27–33)
    • OR Mugen Train Movie
  3. Entertainment District Arc – Season 2 Part 2, Episodes 34–44
  4. Swordsmith Village Arc (Season 3) – Episodes 45–55
  5. Hashira Training Arc (Season 4) – Episodes 56–63
  6. Infinity Castle Movies – watch when all parts are out, after Season 4.

This order matches the in‑universe timeline and current official structure of the anime.

3. Chronological vs Release Order

For Demon Slayer , chronological order and release order mostly match , with the only real fork being how you handle Mugen Train.

  • Release order :
    • Season 1 → Mugen Train movie → Season 2 (TV Mugen Train arc + Entertainment District) → Seasons 3 & 4.
  • Chronological viewing (recommended today):
    • Season 1 → Mugen Train TV arc or movie → Entertainment District → Swordsmith Village → Hashira Training → Infinity Castle movies.

If you accidentally watch the Mugen Train movie and the TV arc, it won’t break the story; you’ll just see the same events twice, with a bit more detail in the TV version.

4. Forum & Trending Talk (Spoiler‑Light)

On anime forums and subreddits, most fans recommend:

  • New watchers:
    • Season 1 → Mugen Train TV arc → Entertainment District → Swordsmith Village → Hashira Training , then wait for Infinity Castle.
  • Binge watchers in 2025–2026:
    • Start now and you can reach Hashira Training and be fully ready for the Infinity Castle trilogy movies hitting theaters.

Viewers often say the jump in animation quality from Season 1 to the later arcs (especially Entertainment District and beyond) makes the chronological ride feel like leveling up with the characters.

5. Mini FAQ for New Watchers

Q: Do I have to watch both Mugen Train movie and TV arc?

  • No. Pick one. TV arc = more content and a bonus first episode; movie = faster, cinematic.

Q: Are there any spin‑offs I must watch for the main story?

  • As of now, the core story is covered by the four seasons plus Mugen Train and the upcoming Infinity Castle films ; you won’t miss key plot if you follow the list above.

TL;DR:
To watch Demon Slayer in true story order: Season 1 → Mugen Train (TV or movie) → Entertainment District → Swordsmith Village → Hashira Training → Infinity Castle movies when released.
