8Muichiro vs. Gyokko
Swordsmith Village Arc | The Mist Descends
When the Mist Hashira finally regains his memories and unleashes his true power against Upper Moon Five, the animation creates a sequence that’s both beautiful and terrifying. What sets this sequence apart is how it visualizes the concept of “mist,” usingsemi-transparent layering effectsand depth-of-field manipulation to create genuine uncertainty about Muichiro’s position.
The animation team excels at conveyingMuichiro’s impossible speedand precision. Rather than relying on typical speed lines, they create multiple after-images that fade like morning mist, making his movements appear almost supernatural. The water effects in Gyokko’s fish tank prison create additional visual complexity that the animation handles flawlessly.
The most memorable sequence is the one where Muichiro executes his Seventh Form. The animation briefly slows down to show his perfect posture before accelerating into a blur of attacks so fast that even the viewer can’t track them. We simply see theaftermath of slashesappearing on Gyokko’s body.
7Tanjiro vs. Mother Spider Demon
Natagumo Mountain Arc | Water Breathing Afterlife
What makes this sequence remarkable isn’t an extended battle, but theemotional weightcarried by a single, perfectly animated sword stroke. After discovering the tragic story of the Mother Spider Demon, Tanjiro approaches her with compassion rather than hatred. The animation beautifully captures this moment of mutual understanding before her death.
As Tanjiro raises his blade, the animation slows dramatically, focusing on the solemn determination in his eyes rather than any sense of triumph. When he delivers the killing blow, the motion is animated with afluid, merciful grace;a clean, swift cut that minimizes suffering. The water effects of his blade trace a beautiful arc that feels more like a ritual than a violent act.
Most powerful is how the animation captures the Mother Spider Demon’s reaction to her peaceful acceptance as the blade approaches. Unlike typical demon slayings, there is no resistance or horror, just release.

6Zenitsu vs. Spider Demon
Episode 17 | Sleep-Fighting Lightning Strike
When a perpetuallyterrified near-death Zenitsufinally reveals his true potential while unconscious, the animation delivers a sequence that’s both shocking and exhilarating. The transition from his normal, cowering state to his sleep-fighting mode is marked by a dramatic shift in animation style, fromexaggerated comedic movementsto precisely choreographed speed lines and impact frames.
What makes this sequence particularly impressive is how it visualizes speed. The yellow lightning effects that accompany Zenitsu’s First Form create the perfect visual metaphor for his instantaneous movement. The camera work compounds this effect, tracking his body as it virtually disappears and reappears across the battlefield.
Most striking is the moment Zenitsu executes his attack. The screen briefly goes black before abrilliant flash of lightningilluminates his perfect form as he slices through the demon. This masterful use of contrast makes the speed and power of his technique viscerally felt by viewers.
5Nezuko vs. Daki
Entertainment District Arc | The Perfect Sibling
What makes this scene exceptional is how it fully showcases Nezuko’s demon abilities throughexplosive, primal animationthat contrasts sharply with the more disciplined techniques of the Demon Slayers.
The animation team creates a visual language uniquely suited to Nezuko’s awakened state. Her movements abandon human constraints, becoming erratic, unpredictable, and frightening in their speed and power. The pink-hued flame effects of her Blood Demon Art create a visual signature that stands in dramatic contrast to Daki’s elegant ribbon attacks.
When she kicks Daki through multiple buildings, the impact frames and debris animation create a sense of devastating power that makes her transformation truly frightening. The sequence expertly balances beauty and horror, showing both the awesome power and the concerning loss of humanity inNezuko’s most unleashed state.
4Tanjiro’s Hinokami Kagura vs. Daki and Gyutaro
Entertainment District Arc | The Dance of Fire and Blood
When Tanjiro fully embraces the Hinokami Kagura against the Upper Moon Six siblings, the animation delivers a sequence that builds upon the famous Episode 19 moment while elevating it further. This sequence is remarkable because it visualizes Tanjiro’sprogressive masteryof the fire techniques, with each swing having more refined flame effects than we saw in his first use against Rui.
The animation excels at showing the physical toll of the Hinokami Kagura. Tanjiro’s movements begin with perfect, flowing forms but gradually become more labored, with subtle animation details showing his increasing exhaustion. His breathing becomes visible in the cold night air, with each exhale animated to show his struggle to maintain the breathing pattern.
Most impressive is how the fire effects interact with the environment. As Tanjiro swings his blade, the flames illuminate the surrounding buildings withdynamic light sourcesthat create a constantly shifting interplay of light and shadow across the battlefield.

3Tanjiro vs. Rui
Episode 19 | The Water Dance That Changed Everything
This is the sequence that catapulted Demon Slayer from popular anime to global phenomenon. When Tanjiro, pushed beyond his limits and fueled by the need to protect his sister, unleashes the Hinokami Kagura dance, the animation shifts into something trulyotherworldly. The flowing water effects give way to brilliant flames that illuminate the dark forest setting.
What makes this sequence legendary isn’t just the technical brilliance, rather how the animation perfectly captures Tanjiro’s emotional breakthrough. As memories of his father performing the ritual dance merge with his present struggle, the animation creates a seamless visual narrative connecting past and present. The moment when Tanjiro slices through Rui’s webs, previously established as unbreakable, sends chills through viewers precisely because theanimation makes you feel the impossible becoming possible.
The sequence concludes with one of anime’s most breathtaking sword slashes, as Tanjiro’s blade meets Rui’s neck in a crescendo of flame and music. This single three-minute sequence permanently changed viewer expectations for what TV anime could deliver.
2Tengen vs. Gyutaro
Entertainment District Arc | The Flamboyant Symphony of Blades
TheSound Hashira’s battle against Upper Moon Six Gyutaroshowcases animation that perfectly embodies Tengen’s flashy, rhythmic fighting style. What distinguishes this sequence is itsmusical quality, Tengen’s movements are animated with a sense of tempo and beat that visual reflects his background as the Sound Hashira.
The dual-blade choreography presented unique animation challenges that Ufotable mastered completely. Each of Tengen’s swings contains multiple attacks, rendered with glinting metal effects and precise arc movements. When his blades meet Gyutaro’s blood sickles, the clashing weapons create visual rhythm through impact frames and particle effects.
Most impressive is how the animation conveys Tengen’s gradually declining condition as the poison takes effect. His initiallyperfect, symmetrical movementsbecome subtly asymmetrical, with micro-hesitations animated into his attacks to show his deteriorating state without explicitly stating it.
1Rengoku vs. Akaza
Mugen Train | The Blazing Heart of a Hashira
The climactic battle between the Flame Hashira and Upper Moon Three represents animation at its most emotionally resonant. As dawn approaches, Rengoku’s flame techniques grow increasinglybrilliant and desperateagainst Akaza’s overwhelming power. What elevates this sequence is how the animation embodies Rengoku’s spirit, his techniques becoming more radiant even as his body fails him, envoking adifferent kind of feeling than Tengen.
The animation team excels at conveying the physical weight and impact of each exchange. When Akaza lands devastating blows, we feel Rengoku’s body crumpling through precise animation of physical trauma. Yet when Rengoku counterattacks, hismovements convey determinationthrough fluid, purposeful motions.
Most impressive is the sequence’s use of lighting. As Rengoku unleashes his final form, the entire screen becomes a canvas of orange and yellow flames that illuminate the pre-dawn darkness. His famous “Set your heart ablaze” line gains tremendous power from animation that literally sets the screen ablaze with his fighting spirit.
