Ch. 121Inabi, Mangekyo Awakens!
Uchiha Yoru’s group waited in Swordsmith Village and ambushed Muzan, but Nakime transported them to the Infinity Castle after Muzan recovered from decapitation. There, Inabi fought Kokushibo and awakened his Mangekyo Sharingan and Susanoo when he was driven to the brink.
- Yoru convinced Tanjiro and Nezuko to stay overnight while Sanemi evacuated the villagers from Swordsmith Village.
- Muzan arrived to claim Nezuko, but Itachi trapped him briefly with Tsukuyomi and Inabi beheaded him with En'yōmaru.
- Muzan regenerated, called for Nakime, and had her transport Yoru, Itachi, Inabi, Tanjiro, and Nezuko to the Infinity Castle.
- Yoru directed Inabi to face Kokushibo alone, and Kokushibo overwhelmed him with Moon Breathing techniques.
- Kokushibo’s attacks and taunts drove Inabi into a rage, awakening his Mangekyo Sharingan and manifesting his Susanoo to repel the crescent blades.
