10 Funniest Demon Slayer Season 4 Scenes, Ranked

Season 4 of Demon Slayer slows down the pace, giving Tanjiro and his allies in the Demon Slayer Corps time to train and prepare for the upcoming fight against Muzan Kibutsuji now that Nezuko has conquered the sun. Knowing that Muzan intends to take Nezuko’s ability to walk in sunlight for himself, making him essentially immortal, the Demon Slayer Corps enlist the powerful Hashira to lead training for all enlisted Corps recruits.

This arc tends to focus more on character development and comedy over action, especially when compared to other seasons in this hit shōnen anime. From the hilarious waterfall training that Tanjiro, Zenitsu and Inosuke undergo to the leotard outfits Mitsuri Kanroji insists her trainees wear, Season 4 delivers a slew of hilarious scenes.

10 Tanjiro’s and Genya’s Crows Sling Insults Whenever They Meet

Season 4, Episode 6, “The Strongest of the Demon Slayer Corps”

After an initiate joins the Demon Slayer Corps, they are given a Kasugai Crow companion to help them with various tasks, such as delivering messages, guiding them to specific locations and conveying orders. These crows have become almost as synonymous with Demon Slayer Corps mythology as the Nichirin blade color meanings. Tanjiro’s crow is named Matsuemon Tennoji and possesses a keen intellect and an inflated ego, while Genya’s crow Hashibami was initially dismissed by his Demon Slayer Corps members when first partnered together.

Tanjiro and Genya’s friendship grew over the series, with the two coming to rely on each other as comrades-in-arms during the pivotal Season 3 arc. Now that all Demon Slayer Corps members require training from the Hashira, these two characters cross paths again. The swordsmen consider each other friends now, but the crows immediately break into a barrage of insults when they meet. The calm, almost happy exchange between the slayers juxtaposed to the inflamed feud between the crows leaves audiences chuckling.

9 Tanjiro Convinces Giyu to Rejoin the Hashira With an Eating Contest

Season 4, Episode 2 “Water Hashira Giyu Tomioka’s Pain”

Season 3 of Demon Slayer concluded after a series of brutal fights between the Demon Slayer Corps and Muzan Kibutsuji’s Upper Moon demons. With broken bones, thick bruises and cuts galore, Tanjiro opens Season 4 in the recovery wing, being nursed back to health by Aoi and Goto. Before he’s recovered fully, a crow from Kagaya Ubuyashiki appears, sending him after Giyu, the Water Hashira.

After an intimate moment where Giyu relives some of his past trauma and memories, a beat of silence passes. In that still moment, a nervous Tanjiro decides that challenging Giyu to an eating contest is the only way to get him to come back — even though the Water Hashira had already made up his mind to return. Tanjiro’s earnest plea for an eating contest is both endearing and delightfully funny, all while strengthening the friendship between these two water-breathing swordsmen.

8 Love Hashira Mitsuri Kanroji Explains how Her Mark Materialized

Season 4, Episode 1, “To Defeat Muzan Kibutsuji”

The previous Swordsmith Village arc in Season 3 of Demon Slayer saw Tanjiro and his friends fighting alongside Love Hashira Mitsuri Kanroji and Mist Hashira Muichiro Tokito after demons invade the village where the Demon Slayer Corps create the crucial Nichirin swords. Infused with sunlight, these swords can cut through demons, making them of vital importance to the slayers.

Thanks to their marks appearing, and by being some of the strongest Hashira swordmasters, Mitsuri and Muichiro slay their respective opponents. Upon returning to the Ubuyashiki Mansion, or the Butterfly Mansion, Corps leadership ask if either of the Hashira can explain what happened to make these powerful markings appear. The onomatopoeia Mitsuri uses, coupled with her extravagant hand gestures as she tries to explain something that happened on pure instinct make for a delightful scene, especially when the keen Muichiro takes over to explain in more scientific detail.

7 The Cuts on the Demon Slayer Corps Members Sting in the Bathhouse

Season 4, Episode 5, “I Even Ate Demons”

After the Hashira decide that each Demon Slayer Corps swordsman must undergo rigorous training, each Hashira selects an aspect of swordplay they wish for their recruits to master. Serpent Hashira Obanai Iguro opts for sword precision, demanding that his trainees strike accurately, for if a slayer’s sword becomes stuck in the terrain while fighting, it could prove fatal.

Obanai feels resentment toward how close Tanjiro and Mitsuri seem to be, so the Hashira decides to make his training as difficult as possible: he ties other Corps members to the wooden beams in the room and demands Tanjiro fight him. If Tanjiro swings carelessly, his attacks strike his fellow trainees. As if such a set-up weren’t hilarious on its own, the trainees then bathe each night, the hot water aggravating their cuts and scrapes. The dread of the bathhouse and the communal reluctance each night make audiences laugh while also being thankful to not be in the trainees’ shoes.

6 Zenitsu Hears Nezuko Speak for the First Time

Season 4, Episode 1 “To Defeat Muzan Kibutsuji”

Now that Tanjiro’s sister, Nezuko, has conquered the sun, and can stand in daylight even as a demon, more of her humanity appears to be returning. Along with that is her ability to speak. Her muzzle is removed and she’s slowly re-learning words and phrases she knew while she was human.

Zenitsu’s reaction when he returns to the recovery wing and is greeted by a smiling Nezuko during the middle of the day makes the viewers’ hearts soar. And then audiences are delivered a prime jab of hilarity when Nezuko calls Zenitsu by Inosuke’s name instead. Zenitsu’s devastated reaction, Nezuko’s obliviousness, Tanjiro’s ignorant conversation with Goto about how Inosuke purposefully taught Nezuko his name only, and the fact that this scene is jam-packed with some of the series’ most popular characters make the whole interaction downright delightful to watch.

5 Tanjiro Pesters Water Hashira Giyu Tomioka To Rejoin Training

Season 4, Episode 2 “Water Hashira Giyu Tomioka’s Pain”

While all the other Hashira agree to the training regime in order to strengthen the Corps members while hoping to unlock their marks, Water Hashira Giyu Tomioka decides against it. He retreats to a private mansion, away from all other members of the Corps, for reasons he doesn’t share with his fellow Hashira members.

Kagaya Ubuyashiki sends a request to Tanjiro, asking him to bring Giyu back into the fold and to be persistent in his efforts. What follows is a hilarious montage of the polite and determined Tanjiro attempting to overcome Giyu’s resistance to discuss the emotional turmoil stopping him from rejoining the others. The scene’s proverbial cherry on top comes from the knowledge that Tanjiro might be one of the nicest shōnen protagonists out there, making the whole pestering that much richer for audiences.

4 Love Hashira Mitsuri Kanroji Teaches Flexibility in Leotards

Season 4, Episode 5, “I Even Ate Demons”

As one of the two female Demon Slayer Corps leaders, Love Hashira Mitsuri Kanroji dominates the screen whenever she appears. Her fighting style revolves more around flexibility and poise, rather than strength and force, and this way of fighting has helped her win crucial battles in the previous Swordsmith Village arc. As such, Mitsuri decides on flexibility training for her trainees after all the Hashira elect to retrain the Corps.

When Tanjiro arrives for his training — and after a quick tea party with pancakes, butter and syrup — Mitsuri gives him a soft pink leotard to change into. Seeing Tanjiro standing proudly and excitedly in his leggings, while the other trainees look embarrassed, makes this scene humorous. But then watching as Mitsuri forces her trainees to make a very sharp, very sudden split with their legs makes this scene all the more laugh-out-loud delicious.

3 Serpent Hashira Obanai Iguro Makes His Students a Part of His Training Exercise

Season 4, Episode 5, “I Even Ate Demons”

After completing Muichiro’s constant movement challenge, Tanjiro heads to Serpent Hashira Obanai Iguro for precision and accuracy when it comes to swings and strikes. Tanjiro likens the experience to fighting in the forest, noting that a slayer’s sword getting lodged in a tree, the ground or anything else could mean life or death for the fighter when he’s in an actual battle.

To ensure this lesson hits hard for Tanjiro — and maybe to punish him for getting too friendly with Mitsuri — Obanai ties the other Corps members to the horizontal and vertical beams in his training house. Their panicked expressions and muffled cries when Tanjiro and Obanai spar strike the perfect blend of tense and hilarious, especially when audiences see how frazzled Tanjiro is about not hitting his fellow fighters.

2 Zenitsu Attempts to Flee from Wind Hashira Sanemi Shinazugawa’s Brutal Training

Season 4, Episode 5, “I Even Ate Demons”

Wind Hashira Sanemi Shinazugawa elects to have infinite slashing training with his Corp members, which basically amounts to him hitting them over and over again. It’s a brutal form of training, one that’s (presumably) meant to build up resistances and defensive strength. In reality though, it just seems to be an opportunity for the slightly unhinged, continuously furious Shinazugawa to vent out his frustrations, which he gladly does once Tanjiro joins, as he seems to dislike the protagonist strongly.

Zenitsu attempts to flee the rigorous training, running into Tanjiro on his way to join it. Beaten to the point where he has to crawl along the ground and walls like a spider, Zenitsu begs Tanjiro to rescue him before Shinazugawa finds them. Flustered, Tanjiro’s polite declines stall the pair long enough for the Wind Hashira to come and collect Zenitsu, with the whole ordeal leaving a stitch in viewers’ sides from the sheer ridiculousness of it all.

1 Tanjiro, Zenitsu and Inosuke Barely Survive Waterfall Training

Season 4, Episode 6 “The Strongest of the Demon Slayer Corps”

For the last leg of their training, Tanjiro, Zenitsu and Inosuke train underneath the Stone Hashira, Gyomei Himejima. Arguably the strongest out of all the Hashira, his extraordinary training regime involves Corps members standing underneath a freezing waterfall, lifting a massive set of heavy logs and then pushing a boulder nearly four hundred feet.

This training portion sees the main trio back together again, for the first time in the season. And their coming together kicks up the antics to hilarious levels. Between Zenitsu hugging a rock to stay warm to Tanjiro nearly taken away by the river’s current, this scene packs a steady stream of pure comedy gold into it, despite its depressingly short length.
