Zenitsu Agatsuma might be one of the most chaotic characters in Demon Slayer, but that’s exactly what makes him hilarious. Equal parts coward, romantic, and reluctant genius, Zenitsu is the comedic heart of the series—screaming, sobbing, and stumbling his way through life-threatening battles. Yet, despite his nervous breakdowns and dramatic meltdowns, he also manages to shine with jaw-dropping moments of unexpected brilliance. Whether he’s chasing after Nezuko or fainting into God mode, Zenitsu never fails to leave an impression. Here are the Top 10 Funniest Moments Featuring Zenitsu Agatsuma that had us laughing out loud and loving every second of his panic-fueled journey.
#10: Zenitsu Clings to Tanjiro for Dear Life
The first time Zenitsu meets Tanjiro is an instant classic. After Final Selection, Tanjiro finds Zenitsu lying on the ground, begging a girl to marry him because he believes he’s going to die soon. What follows is an absurd meltdown as Zenitsu latches onto Tanjiro like a child terrified of thunder. He clings, cries, and pleads for protection, while Tanjiro—stoic as always—just stares in disbelief. The visual of Zenitsu gripping his new “friend” like a human security blanket while screaming about imminent death is unforgettable. It sets the tone for Zenitsu’s entire presence in the show: always dramatic, always loud, and always somehow charming in his cowardice. You can’t help but laugh and wonder how this guy survived Final Selection at all.
#9: Zenitsu Screams at a Sparrow
When Zenitsu is assigned a sparrow instead of a crow like the other Demon Slayers, it leads to one of his most ridiculous rants. The bird, named Chuntaro, chirps away enthusiastically while Zenitsu proceeds to scream at it in frustration, demanding why he didn’t get a “cool bird” like everyone else. His over-the-top fury directed at an adorable sparrow is comedy gold. Even better, Chuntaro just keeps tweeting away, completely unfazed. The juxtaposition of Zenitsu’s fury and the bird’s calm chirping makes the scene a classic. It’s so ridiculous you can’t help but burst out laughing. And the best part? Chuntaro stays by his side loyally, no matter how many tantrums Zenitsu throws.
#8: Zenitsu’s Reaction to Nezuko Exiting the Box
When Nezuko first emerges from her box in front of Zenitsu, his entire personality implodes. He instantly switches from panic mode to over-the-top prince mode, declaring his love and kneeling in awe like she’s descended from heaven itself. The guy who was just sobbing seconds ago now speaks in poetic tones about Nezuko’s beauty, while hearts practically explode from his eyes. Tanjiro’s blank expression as Zenitsu fawns over his sister only adds to the comedy. It’s the beginning of Zenitsu’s one-sided love saga, and the sheer intensity of his “romantic” reaction had fans howling. Whether he’s chasing Nezuko down the street or begging her to notice him, Zenitsu’s over-the-top infatuation never fails to amuse.
#7: Zenitsu Hides Under the Tatami
During the Entertainment District Arc, when the trio infiltrates the district in disguise, Zenitsu is forced to play a geisha-style undercover role—complete with makeup, a wig, and a kimono. Already hilarious on its own. But the real gem comes when, after being pushed to the brink by Daki’s haunting presence, Zenitsu hides under the floorboards to escape detection. Yes, he literally rips up the tatami mat and wedges himself in like a cartoon character. His eyes bulge with terror, and his shrieking is so loud it’s amazing the demon didn’t find him right away. It’s physical comedy at its finest, and another moment where his cowardice becomes so extreme it loops back to being hysterically entertaining.
#6: Zenitsu Slaps Tanjiro for Insulting Nezuko
In a surprising yet hilarious turn, Zenitsu loses his temper—not at a demon, but at Tanjiro—for supposedly not appreciating Nezuko enough. When Tanjiro downplays his relationship with his sister (probably to avoid Zenitsu’s obsessive rants), Zenitsu responds by slapping him repeatedly and screaming about how “precious” she is. What makes it funnier is how serious Zenitsu is—his voice cracking with emotion, as though Tanjiro has committed the greatest sin of all time. Meanwhile, Tanjiro is left blinking in disbelief, probably wondering how this became his life. The absurdity of Zenitsu’s passion for Nezuko mixed with his shameless aggression makes this scene both ridiculous and unforgettable.
#5: Zenitsu Faints—Then Wipes Out a Demon Instantly
One of Zenitsu’s defining gags is his tendency to faint from fear—and then unconsciously unleash pure lightning-powered destruction. The first time this happens, during the battle at the Tsuzumi Mansion, is absolutely shocking and hilarious. Zenitsu, screaming and shaking moments earlier, collapses in terror. Just when it looks like he’s about to be devoured by a demon, he suddenly enters a trance and uses Thunder Breathing First Form: Thunderclap and Flash. In one impossibly fast movement, he slices the demon to pieces—then wakes up confused, crying, and still convinced he’s about to die. The disconnect between his unconscious badassery and waking cowardice makes this one of the most iconic and funny reveals in the series. It’s a joke with massive payoff—and it never gets old.
#4: Zenitsu Argues with a Child
During the Natagumo Mountain Arc, Tanjiro and Zenitsu are temporarily placed under the care of the Butterfly Mansion. There, they’re tasked with training alongside young girls like Aoi and the tiny trio of Naho, Kiyo, and Sumi. Zenitsu, in full over-the-top glory, begins arguing with children, accusing them of torturing him with training drills. His rants about the horrors of rehabilitation training—delivered with tear-streaked cheeks and dramatic flailing—are laugh-out-loud funny, especially because his tormentors are little girls who remain completely unbothered. The more Zenitsu complains, the more they calmly push him through the drills. His comedic suffering is theatrical gold, especially when compared to how Tanjiro and Inosuke embrace the process. Zenitsu turns what should be a recovery montage into a three-act comedy.
#3: Zenitsu Screams About Being Tricked Into the Entertainment District
When Tengen Uzui ropes Tanjiro, Inosuke, and Zenitsu into infiltrating the Entertainment District, Zenitsu’s reaction is nothing short of hysterical. Upon realizing he’s being forced into a mission disguised as a courtesan, he loses it. His high-pitched voice, frantic complaints, and wild expressions make the scene unforgettable. He accuses Tengen of betrayal, screams about the inappropriateness of it all, and desperately tries to escape—only to be dragged along anyway. What makes it even funnier is how completely opposite Inosuke and Tanjiro are—stoic and cooperative while Zenitsu flails like a toddler. His sheer lack of chill in every situation adds a layer of comedy to even the most dangerous missions, and his exaggerated reaction to this assignment had fans in stitches.
#2: Zenitsu Plays the Shamisen—Furiously
In his undercover role at the Entertainment District, Zenitsu ends up in a brothel disguised as a girl. At first, it seems like he’s about to blow his cover—but then something unexpected and hilarious happens. He sits down with a shamisen and shreds it like a rock star. His fingers move at lightning speed, and his music captivates the entire house. It’s such a bizarre yet brilliant twist—this crying, shrieking ball of nerves is suddenly a musical prodigy. And he plays it angrily. His furious, rapid strumming is both impressive and absolutely hysterical. It turns his character into a living contradiction, which only makes fans love him more. He’s crying one moment and outplaying everyone in the district the next.
#1: Zenitsu Tries to Marry Every Girl He Sees
Zenitsu’s over-the-top obsession with finding a wife reaches legendary heights in the early episodes when he’s seen proposing to random girls on the street. In one unforgettable moment, he clings to a terrified woman’s leg, begging her to marry him because he could die at any time. The poor girl is trying to walk away while Zenitsu screams about loneliness, love, and how unfair life is. The scene is pure chaos—Tanjiro has to physically drag him off the woman, while Zenitsu sobs about wanting to experience romance before he dies. It’s outrageous, embarrassing, and absolutely hilarious. It perfectly captures his wildly inappropriate, overdramatic charm. While other characters think about training or fighting, Zenitsu is thinking about love—all the time. And it’s that absurd tunnel vision that makes him one of the funniest characters in anime.
Zenitsu Agatsuma is more than just comic relief—he’s an explosion of chaos, charm, and confusion all wrapped into one shrieking, sword-wielding package. Whether he’s fainting mid-battle, arguing with children, or proposing to strangers, Zenitsu knows how to steal every scene. His blend of cowardice, sincerity, and hidden power makes him one of the most entertaining parts of Demon Slayer—and one of the funniest characters in modern anime.
