While the Demon Slayer manga introduced us to the Hashira, the power group of demon hunters, the anime offers a deeper exploration of these elite pillars.

These anime scenes give us a better understanding of the Hashira and provide more details about their background, personalities, and fighting styles that were not included in the manga.

Whether you’re an anime viewer curious about what you may have missed or a manga reader eager to relive these character-enriching moments, we’ll guide you through the fascinating world of Demon Slayer’s extensive content.

What is filler content in anime?

In anime, filler refers to episodes or scenes that are not directly adapted from the source material, usually manga. These episodes were made for different reasons.

When the anime catches up to the manga storyline, filler episodes are added to create a buffer and allow the manga to produce more content before the anime runs out of material.

In the Demon Slayer anime, the filler scenes expanded Hashira’s character development and built the tension between Muzan Kibutsuji’s demon forces and the Demon Slayer Corps.

The filler scenes we discuss are brand new content that wasn’t in the manga. Although some episodes do not follow the same order as the manga, we only highlight the new scenes that are unknown to manga readers.

Episode 1 – Defeating Muzan Kibutsuji

The manga does not include a scene from the first episode of Season 4. This scene, set between the Season 3 finale and the beginning of Season 4, featured Wind Hashira Sanemi Shinazugawa and Serpent Hashira Obanai Iguro on a rescue and assassination mission.

They are tasked with tracking down a demon responsible for kidnapping civilians near a village. Their investigation leads them to an abandoned castle, which serves as a demon stronghold. Disgusted by the demons’ excesses, the two Hashira invade the castle, quickly defeating the ambushing demons.

One demon attempts to flee by jumping off the edge of the castle, revealing a glimpse of the Infinity Castle as it escapes. However, it disappears before Shinazugawa and Iguro could reach the Infinity Castle.

After this special scene, the episode continues with the opening events of the To the Hashira Training arc, which adapts chapters 128 through 131 of the manga.

Episode 2 – Water Hashira Giyu Tomioka’s Pain

This episode follows the manga closely.

Episode 3 – Fully Recovered Tanjiro joins Hashira training

The scene where former Sound Hashira Tengen Uzui pushes the lower-ranked demon hunters to their limits is similar to chapter 129 of the Hashira Training arc in the manga. The anime expands on this by including the perspectives of the demon hunters, who describe the training as hell.

The parts where Tanjiro shows his superior skills, strength, and endurance compared to the other demon hunters, along with the three women of Tengen personally thanking Tanjiro for saving them during Season 2’s Entertainment District arc, are also anime exclusives.

These scenes do a great job of fleshing out the Demon Slayer Corps and highlighting the relationships Tanjiro formed with his comrades from Season 2. The scene where the two demon hunters go on patrol appears in the manga, but is more prominent in the anime.

The two biggest scenes in episode 3 that are not in the manga are Tengen challenging all the demon hunters and Tanjiro to fight him in the mountains, and the Wind Hashira Sanemi Shinazugawa and the Serpent Hashira Obanai Iguro challenging each other in a temple.

Episode 4 — Putting a Smile on Your Face

Episode 4 features numerous new scenes exclusive to the anime. These include an in-depth look at Mist Hashira Muichiro Tokito’s grueling sparring sessions, which led to significant character development for the Pillar.

Tokito explains that he trains the demon hunters as hard as he can because he wants them to survive and have a long life after defeating Muzan.

The part where Mr. Kanamori is invited from the Swordsmith Village to help improve the Demon Slayers’ Nichirin blades is also new, along with the paper airplane competition at the end of the episode.

Finally, the scenes where Tokito, Iguro, and Shinazugawa have secret sparring sessions are exclusive to the anime.

Episode 5 — I Even Ate Demons

Most of the scenes in episode 5 closely follow the manga, especially chapter 132. The difference lies in the more in-depth look at Serpent Hashira Obanai Iguro’s training.

Additionally, it features scenes of Tanjiro and the other demon hunters recovering after each training session with Iguro.

Episode 6 – The Strongest of the Demon Slayer Corps

Episode 6 is based on the events of chapters 135 and 136, which are faithfully adapted from Koyoharu Gotouge’s original manga.

The only difference is that the anime had more detail than the manga, especially in Tanjiro’s interactions with the other demon hunters. These additional scenes gave more depth to the series’ supporting characters and emphasized the camaraderie within the Demon Slayer Corps.
