Muichiro pushes Gyokko into revealing his true merman form, then beheads the Upper Rank with Obscuring Clouds. Elsewhere Zohakuten's wooden dragons nearly kill Tanjiro before Mitsuri arrives to turn the tide.
The 53rd anime episode and ninth of the third season adapts chapters 120 through 122. Goaded by Muichiro's insults toward his craft, Gyokko abandons his vase and assumes a serpentine merman form that can transform anything it touches into fish. The Mist Hashira, fully empowered by his mark and a renewed memory of his rescue by Amane Ubuyashiki, evades the demon's lethal blows and ultimately decapitates him. The episode then shifts to Tanjiro, who is swallowed by one of Zohakuten's wooden dragons before the newly arrived Mitsuri cuts him free.
After trading taunts, Gyokko sheds his skin and reveals a transparent-scaled body he claims is harder than diamond. Muichiro counters his fish-conjuring fists with Mist Breathing forms and recalls being saved from death by Amane and her daughters, fueling the deep rage that drives his training.
Using Obscuring Clouds, Muichiro confounds Gyokko's sight and severs his neck, then mutilates the head to ensure the demon's death. Afterward he collapses from the accumulated poison, but Kotetsu reveals that Tanjiro's gift of Rengoku's tsuba shielded him from a fatal wound, and Muichiro sees a vision of his reunited family.
Zohakuten's dragons rupture Tanjiro's eardrums and unleash combined wind, lightning, and sonic attacks before swallowing him whole. Mitsuri leaps in, races along a dragon's neck to split its head open, and rescues Tanjiro, then advances to face the manifestation of hatred herself.

Demon Slayer: Infinity Castle earned $778 million globally and nearly 40 billion yen in Japan, but it still couldn't top Mugen Train's domestic record. Here's why that barely matters....

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....
The second eyecatcher loosely recreates chapter 120's cover. The anime extends the scene of Amane and her daughters tending Muichiro and Yuichiro and shows Muichiro training relentlessly while injured. Gyokko's Killer Fish Scales is restaged as impossible gliding movements around Muichiro rather than a destructive frenzy. The anime also depicts Muichiro slicing Gyokko's severed head vertically and mincing it, producing an animation error where both eyes remain intact as the demon disintegrates. Mitsuri ensnaring a dragon with her whip blade is an anime-only addition.
In Demon Slayer episode 53, Muichiro Tokito forces Gyokko into his true merman form and beheads the Upper Rank using Obscuring Clouds. The episode then shifts to Tanjiro, who is swallowed by one of Zohakuten's wooden dragons before Mitsuri arrives to cut him free.
