Kimetsu No Yaiba Episode 12 May 2026

Separated from Tanjiro and paralyzed by fear, Zenitsu is cornered by a demon. In a moment of pure terror, he passes out—only to reveal that he is a deadly efficient "sleepwalker." While unconscious, he performs a single, lightning-fast strike: Thunder Breathing, First Form: Thunderclap and Flash , instantly decapitating the demon.

Reviewers from Anime News Network and Screenspy highlighted the fluid animation during the mansion's gravity-defying shifts and Zenitsu’s lightning strike.

Critics and fans generally praised the episode for its animation quality, particularly the "room-shifting" visual effects and Zenitsu's first real action scene.

The episode picks up with Tanjiro Kamado , Zenitsu Agatsuma , and the young boy Shoichi trapped inside a mansion where the rooms rotate and change whenever the demon Kyogai plays his tsuzumi drums.

The episode introduces the concept of Marechi blood. Shoichi’s older brother possesses this rare blood, which is significantly more nutritious for demons, making him a high-value target and the reason they were kidnapped. Critical Reception

In episode 12 of Demon Slayer: Kimetsu no Yaiba , titled the story continues the intense Tsuzumi Mansion Arc. The episode focuses on the group being split up within the ever-shifting rooms of the mansion, showcasing the unique (and often bizarre) fighting styles of the new supporting cast members.
