Nobu Jo
Nobu Jo is a fictional character in Kimetsu no Yaiba (Demon Slayer). He is a minor antagonist who appears during the Swordsmith Village Arc.
Nobu Jo is a demon affiliated with Muzan Kibutsuji. He is not one of the Twelve Kizuki. His primary ability is to manipulate and control the bodies of humans.
During the Swordsmith Village Arc, Nobu Jo is tasked with infiltrating the village to locate and eliminate the swordsmiths who create the Nichirin blades used by the Demon Slayer Corps. He accomplishes this by taking control of the villagers and turning them against one another, creating chaos and distrust.
He is ultimately defeated by Tanjiro Kamado and Nezuko Kamado, along with the efforts of other Demon Slayers present in the village. Nobu Jo's defeat contributes to Muzan's understanding of Nezuko's sunlight resistance, a crucial plot point in the series.
