by The complete rebroadcast of Demon Slayer: Kimetsu no Yaiba continues to reignite fan excitement in 2026, and Episode 6, titled:
“The Swordsman Accompanying a Demon”
once again reminded viewers why the series became a worldwide phenomenon.
The episode aired on May 10, 2026, as part of the ongoing full-series rebroadcast event, and fans immediately flooded social media with nostalgic reactions such as:
- “My weekly Sunday reward!”
- “The real battles finally begin!”
- “Nezuko’s kick is still legendary!”
- “The Swamp Demon is seriously creepy!”
Episode 6 marks one of the first true combat missions for:
- Tanjiro Kamado
and also features one of the earliest iconic moments for:
- Nezuko Kamado
whose explosive entrance during the battle left a major impression on anime fans when the episode originally aired in 2019.
The Emotional Beginning of Tanjiro’s Journey
At the start of Episode 6, Tanjiro prepares to officially leave for his first mission as a member of the Demon Slayer Corps.
Before departing,
- Sakonji Urokodaki
explains several important details about the Demon Slayer uniform and Tanjiro’s newly forged Nichirin Blade.
The special uniform is made from durable fibers resistant to attacks from weaker demons, while the Nichirin sword changes color depending on its owner.
When Tanjiro’s blade turns black, Urokodaki explains that black blades are considered mysterious and uncommon. Some even believe swordsmen with black blades struggle to rise through the ranks.
Despite the ominous explanation, Tanjiro calmly responds:
“I don’t know what will happen in the Demon Slayer Corps, but I will definitely turn Nezuko back into a human.”
This moment perfectly captures Tanjiro’s determination and emotional strength, qualities that helped make him one of anime’s most beloved protagonists.
Fans Loved Nezuko’s Adorable Moments Before the Mission
Before the action begins, the episode also delivers several heartwarming scenes featuring:
Nezuko Kamado
Fans especially adored the scenes where Nezuko:
- Peeks out from under her blanket
- Reacts shyly to new clothes
- Returns to the futon “like a cat.”
- Shrinks down to fit inside the wooden box
Social media reactions included:
- “Nezuko peeking out is unbelievably cute.”
- “She acts exactly like a sleepy cat.”
- “Tiny Nezuko getting into the box is adorable.”
These early episodes helped establish the emotional warmth between Tanjiro and Nezuko before the series’s larger-scale battles began.
The Wooden Box Became One of the Series’ Most Iconic Symbols
To protect Nezuko from sunlight during the day, Urokodaki gives Tanjiro:
A special box for carrying Nezuko
The box is made from lightweight Kirigumo cedar and coated with strong rock lacquer for extra durability.
Tanjiro gently asks Nezuko to climb inside, and after some hesitation, she quietly enters the box.
As he closes it, Tanjiro softly says:
“We’ll always be together from now on.”
This emotional scene remains one of the defining early moments of the series and highlights the sibling bond that serves as the emotional core of Demon Slayer.
The Swamp Demon Introduces True Horror Into the Series
After arriving in a town in the northwest for his mission, Tanjiro encounters:
- Kazumi
a distraught young man whose girlfriend, Satoko, has disappeared.
As night falls, the episode shifts into horror territory.
A terrifying black stain begins spreading beneath a young woman inside her own home before monstrous arms drag her underground.
Fans reacting to the rebroadcast commented:
- “This scene is genuinely terrifying.”
- “The idea that demons can invade homes is horrifying.”
- “The tension in the early episodes is incredible.”
Unlike later arcs featuring large-scale battles against elite demons, the early episodes emphasize the fear ordinary civilians feel toward demons.
The Swamp Demon arc is often remembered as one of the anime’s creepiest early missions.
Swamp Demon Remains One of the Series’ Most Disturbing Early Villains
Tanjiro eventually discovers the culprit:
Swamp Demon
a supernatural demon capable of traveling through swamp-like dimensional spaces hidden beneath the ground.
The demon’s unsettling appearance, teeth-grinding sounds, and twisted obsession with young women made many viewers uncomfortable in the best horror-anime sense.
Fans online reacted with comments such as:
- “The Swamp Demon is disgusting.”
- “Its teeth-grinding sound still creeps me out.”
- “For an early villain, it was surprisingly dangerous.”
The demon’s ability to split itself into three separate bodies also made the fight far more difficult for Tanjiro than expected.
Tanjiro’s Water Breathing Techniques Continue to Impress
During the battle, Tanjiro demonstrates several Water Breathing techniques, including:
- Fifth Form
- Eighth Form: Waterfall Basin
The animation of:
Water Breathing
immediately became one of the anime’s defining visual trademarks when the series first aired.
Fans revisiting Episode 6 praised the choreography once again:
- “Waterfall Basin still looks amazing.”
- “The Water Breathing animation changed anime action forever.”
- “Even after years, ufotable’s animation is stunning.”
The rebroadcast reminded viewers how revolutionary the series’s visual presentation felt in 2019.
Nezuko’s Famous Kick Scene Still Excites Fans
The most celebrated moment of Episode 6 arrives when:
Nezuko Kamado bursts out of the box
to save Tanjiro during the battle.
Her sudden appearance and devastating kick attack instantly became one of the episode’s most iconic scenes.
Social media exploded with reactions:
- “Nezuko Kick!!!”
- “Her entrance is still unbelievably cool!”
- “This scene made me love Demon Slayer.”
- “Nezuko protecting Tanjiro never gets old.”
The moment perfectly demonstrates the emotional connection between the siblings while also establishing Nezuko as far more than just someone Tanjiro protects.
Instead, she actively fights beside him.
Urokodaki’s Hypnosis Explains Why Nezuko Protects Humans
The episode also reveals that while Nezuko slept:
- Sakonji Urokodaki
used psychological suggestion techniques to reinforce the idea that:
- Humans are family
- Demons are enemies
- Humans must be protected.
This explanation became an important foundation for Nezuko’s unique role within the story.
Fans often praise this aspect of the narrative because it gives emotional weight to Nezuko’s actions rather than simply treating her as a standard “friendly demon.”
Ryohei Kimura Voices the Swamp Demon
The Swamp Demon is voiced by:
Ryohei Kimura
well known for roles such as:
- Kotaro Bokuto in Haikyu!!
- Ryota Kise in Kuroko’s Basketball
To celebrate the rebroadcast, official cast comments were released, with Kimura humorously stating:
