I Even Ate Demons...

This is the sixtieth episode of the anime and the fifth of its fourth season. After Mitsuri's stage, Tanjiro moves on to Obanai Iguro's training and finds the Serpent Hashira waiting and visibly furious. He must refine his swordsmanship under harsh conditions, then advances to Sanemi Shinazugawa, where a clash over Genya brings the program to a sudden stop.

Mitsuri welcomes Tanjiro with buttered pancakes and puts the recruits through dancing and stretching drills, forcing them into painful splits with sheer strength. At Obanai's dojo, recruits are tied to posts as obstacles while Tanjiro tries to strike chimes between them, his hesitation drawing repeated blows. By imagining himself and Obanai alone in a forest, Tanjiro learns to ignore the distractions and finally lands a hit on the Hashira's haori to pass.

On the way to Sanemi, Tanjiro finds a panicked Zenitsu fleeing the Wind Hashira's brutal endless-attack drills. Tanjiro endures the punishment, then witnesses Sanemi berating Genya and demanding he quit the Corps. When Genya admits he ate demons to gain strength, Sanemi tries to gouge his eyes, and Tanjiro shoves Genya clear. Refusing to let Sanemi decide his brother's path, Tanjiro fights him to a standstill that lasts until sundown. The Corps reprimands Tanjiro and suspends his training with Sanemi. The next day he and Zenitsu discover Gyomei Himejima's stage, where recruits chant beneath a waterfall while the Stone Hashira hauls heavy logs across burning ground.

The episode adapts the remainder of chapter 132 and chapter 133. The anime extends Tanjiro's time with Mitsuri and Obanai, adding scenes such as Mitsuri feeding him pancakes and Obanai stewing over her letter of praise. A volume extra comparing the Shinazugawa brothers' fight to Tanjiro's playful tussles with his younger brother Shigeru is adapted here. The first eyecatcher recreates chapter 132's cover, and the second recreates chapter 133's.
