Demon Slayer Chapter 194

Demon Slayer Chapter 194, titled "Burn Scars," reveals Yoriichi Tsugikuni's enduring impact on Muzan Kibutsuji as his ancient wounds resurface, while Obanai Iguro, despite his own severe injuries, courageously defends Tanjiro Kamado in the relentless Sunrise Countdown Arc. Yushiro, tending to a mangled Chachamaru, reveals the cat is also a demon he transformed before the battle, then dispatches other Demon Slayers with anti-Muzan serum for the injured Inosuke Hashibira, Kanao Tsuyuri, and Zenitsu Agatsuma. Assessing Gyomei Himejima's critical condition, Yushiro worries about the Hashira's ability to fight with severe blood loss and a severed leg, pleading for Tamayo to aid Tanjiro, who he believes cannot last alone against Muzan with 50 minutes until sunrise.

Meanwhile, Tanjiro continues his desperate attempt to link the Sun Breathing forms against Muzan. His left sleeve is ripped, and he realizes that merely connecting forms is insufficient; he must precisely target Muzan's vital organs, but a lack of oxygen nearly causes him to black out. He tries to regain focus by sniffing out Muzan, but almost succumbs to an attack before Obanai Iguro heroically intervenes, scooping him to safety. Obanai deftly dodges Muzan's attacks, carrying Tanjiro out of danger, infuriating Muzan who questions their stubborn refusal to die. Tanjiro's vision clears, and he recognizes Obanai, whose face is horribly mutilated with slashes across his eyes. Obanai, however, dismisses his injuries, explaining they were from Muzan's earlier assault, and reassures Tanjiro that his impaired vision won't hinder him significantly due to his weak left eye and the aid of his snake, Kaburamaru.

Confirming Tanjiro's recovery, Obanai releases him and fiercely engages Muzan, tackling him one-on-one, much to Tanjiro's shock. With Kaburamaru's guidance, Obanai skillfully evades Muzan's attacks amidst the crumbling buildings, as Tanjiro rushes back to use Sun Breathing, aiming to distract Muzan. Muzan, annoyed that a mere snake is relaying crucial information, becomes enraged by his inability to kill the severely wounded Demon Slayers, attributing their resilience to Tamayo's aging potion. As Tanjiro continues to evade, he observes Muzan weakening but also feels his own body giving out. Suddenly, Muzan's body begins to sprout old, familiar burn scars—the cellular-level wounds inflicted by Yoriichi Tsugikuni centuries ago, which Muzan was never able to fully heal. Realizing these are Muzan's weak spots, Tanjiro declares that Yoriichi is still guiding them, marking a crucial turning point in the climactic Sunrise Countdown Arc of the Demon Slayer manga.
