The next mission is in Asakusa, Tokyo. Tanjiro is taken aback by the opulent Taisho Era cityscape, but soon picks up the demon’s scent there. His pursuit of the scent leads him to Muzan Kibutsuji. Tanjiro attempts to strike him down. But Kibutsuji transforms a passerby into demon, triggering a commotion. As Tanjiro desperately tries to get things under control, someone appears before him...
The bystander Kibutsuji strikes turns and bites his wife he was walking with, forcing Tanjiro to leave Kibutsuji to subdue him, and Kibutsuji takes advantage of the chance to leave with his "family." Police arrive and try to pull Tanjiro off the demon, but he won't move as this will let the demon escape.
A nearby demon, Tamayo, uses her Blood Demon Art, Blood Bewitchment: Scent of Illusory Blood, Visual Dream spell to blind and distract the police, having noticed Tanjiro was still trying to save the demon and wants to help. She confirms she and her companion Yushiro are demons to a shocked Tanjiro, but she is also a doctor who wants to kill Kibutsuji. Kibutsuji meanwhile, sends his family ahead to their home and orders two demons to bring him Tanjiro's head.
Tanjiro retrieves Nezuko and Yushiro leads him to Tamayo's cloaked house, where she is treating the bitten woman, her husband restrained in the basement. Tamayo tells Tanjiro she can treat the woman without being overcome by hunger because she has tweaked her body and removed Kibutsuji's curse so she and Yushiro can live without eating humans, needing only a bit of human blood. She also reveals she turned Yushiro into a demon, despite the general belief only Kibutsuji can do so, as she developed the ability after two hundred years. She clarifies she's not trying to make more demons, and only turns humans who agree to it when it is clear they will otherwise die.
Tamayo is also searching for a way to return a demon to a human and asks Tanjiro to let her study Nezuko's blood, as she is special for being able to sleep long periods of time without eating and for freeing herself from the bloodlust, and to bring more blood from other powerful demons for her to study. Tanjiro agrees to help.
The two demons Kibutsuji sent, Susamaru with temari balls, and Yahaba with eyes with arrows for pupils on his palms, find and ruthlessly attack the house.
Characters in Order of Appearance
- Tanjiro Kamado
- Muzan Kibutsuji
- Yoriichi Tsugikuni (Flashback)
- Nezuko Kamado
- This episode marked the first time that a Bright Red Nichirin Sword was shown in the anime.
- This episode incorrectly depicts Muzan's flashback, showing the Demon King's encounter with the swordsman in an alley, despite the actual encounter occurring in a stone path surrounded by bamboo. This may be attributed to the fact that the episode was released 7 months before Chapter 186, where the encounter was more thoroughly shown.
