With Season 4 of Demon Slayer: Kimetsu no Yaiba coming to a close, now is the perfect time to dive into the manga and explore the epic Infinity Castle Arc — one of the most anticipated storylines yet to be fully animated.
The fourth season adapted the shortest arc in Koyoharu Gotouge’s manga, the Hashira Training Arc. The anime expanded this storyline with original content, giving more depth to each Hashira — characters who previously had limited screen time prior to the final showdown against Muzan Kibutsuji.
The arc concluded with Episode 8, a longer-than-usual finale that not only wrapped up the training arc but also set the stage for the explosive final battles.
If you’re eager to get ahead of the anime and witness the epic conclusion of Demon Slayer, you should begin reading the manga from:
📚 Chapter 140
(Start of the Infinity Castle Arc)
This marks the beginning of the final saga, which is packed with intense one-on-one battles, major reveals, and emotional farewells.
While no official release date has been set, Demon Slayer’s final arc will be adapted into a trilogy of theatrical films. This trilogy is expected to cover:
That’s a total of 66 chapters remaining — a grand finale that’s too epic for TV alone.
Infinity Castle is not just a setting — it’s the battleground where every major character faces their ultimate opponent. Each Hashira gets a dedicated moment to shine in high-stakes combat, making it one of the most beloved arcs in the series.
Given the complexity and intensity of these battles, fans agree:
Only a movie trilogy could do it justice.
