The anime wave in India is no longer a niche—it’s a full-blown cultural moment. And leading the charge is Demon Slayer: Infinity Castle, the latest cinematic installment in the globally beloved Kimetsu no Yaiba franchise. With its India release set for September 12, the film has already shattered records in advance bookings, including 5 am screenings in cities like Mumbai and Pune. But if you’re new to the series or short on time, don’t worry—you don’t need to binge all 50+ episodes to enjoy the movie.
This guide is your shortcut to understanding the essential arcs, characters, and emotional stakes that make Infinity Castle a must-watch. Whether you’re a long-time fan or just anime-curious, here’s how to catch up quickly and dive into the action.
Infinity Castle: Breaking Records Before Release
Before we get into the episode guide, let’s talk numbers. Demon Slayer: Infinity Castle has already sold over 2.5 lakh tickets in India for its opening weekend. It’s the first Japanese film to get 5 am shows in Indian theatres, with screenings starting as early as 5:15 am in Pune and 5:20 am in Navi Mumbai. Trade reports estimate Rs 15 crore in advance bookings, surpassing previous anime hits like Suzume and Jujutsu Kaisen 0.
With over 1700 screens nationwide and IMAX formats included, this is the widest anime release India has ever seen. The hype is real—and deserved.
Do You Need to Watch the Entire Series?
Short answer: No.
While Demon Slayer is known for its emotional depth and stunning animation, you don’t need to watch every episode to understand Infinity Castle. The film picks up from the end of the Hashira Training Arc and dives straight into the final battle against Muzan Kibutsuji and the Upper Rank demons. To get up to speed, just watch these three key episodes/arcs:

1. Mugen Train Arc – Episodes 6 & 7
These episodes introduce Akaza, one of the most powerful Upper Rank demons, and explore his tragic backstory and intense clash with Kyojuro Rengoku, the Flame Hashira. Akaza’s ideology and his connection to Tanjiro are central to the emotional weight of Infinity Castle. Even if you’ve seen the Mugen Train movie, revisiting these episodes helps reinforce the stakes.
Why it matters: Akaza returns in Infinity Castle, and understanding his motivations adds depth to the conflict.
2. Swordsmith Village Arc – Episode 1
Often skipped, this episode sets the stage for the remaining Upper Rank demons and their hierarchy. It introduces Gyokko and Hantengu, and hints at the growing threat of Muzan’s stronghold. This arc also showcases the evolving dynamics between Tanjiro, Nezuko, and the Hashira.
Why it matters: It builds the foundation for the demon hierarchy and foreshadows the battles in Infinity Castle.
3. Hashira Training Arc – Final Episode
While the arc itself is slower-paced, the final episode is crucial. It shows how Tanjiro and the Hashira prepare for their assault on the Infinity Castle. The transition from training to war is seamless, and this episode acts as a narrative bridge to the movie.
Why it matters: It sets up the entry into Infinity Castle and explains the characters’ readiness for the final showdown.
Why Selective Viewing Works
Unlike many long-running anime series, Demon Slayer is tightly written. There’s minimal filler, and each arc contributes meaningfully to character development and plot progression. By focusing on these three episodes/arcs, you’ll grasp:
- The emotional stakes between Tanjiro and Akaza
- The structure and threat of the Twelve Kizuki
- The unity and strength of the Hashira Corps
This approach saves time while ensuring you’re not lost during the movie’s intense battles and emotional turns.
The Rise of Anime in India
The success of Infinity Castle isn’t just about one film—it’s a reflection of anime’s growing popularity in India. From Naruto reruns to Jujutsu Kaisen watch parties, anime has evolved from underground fandom to mainstream pop culture. The 5 am screenings of Infinity Castle aren’t just shows—they’re celebrations, with fans cosplaying, cheering, and sharing the experience online.
Distributors like Sony Pictures India have taken note, expanding the release from an initial 700 screens to over 1700 due to overwhelming demand. This marks a turning point for anime in India, proving it can compete with Bollywood and Hollywood blockbusters.
