Demon Slayer has one trap: the Mugen Train arc exists twice — as a movie and as an extended TV version. You only need one. Here is the correct order, verified against air dates.
- TV · 26 ep · 2019
The start of Tanjiro and Nezuko's story. Watch it all.
- Movie · 2020
Continues right after Season 1. Alternative: the 7-episode TV version (2021) covers the same story and adds one extra episode at the start — pick one, not both.
- TV · 11 ep · 2022
Listed on AniList as Yuukaku-hen. Follows Mugen Train.
- TV · 11 ep · 2023
- TV · 8 ep · 2024
- Movie · 2025
First of a movie trilogy that closes the story. Parts 2 and 3 have no release date yet.
