Arc 19Makomo’s Sword and the Upper Ranks
Hane trained Makomo and her junior disciples, and Makomo’s swordsmanship led her into the Demon Slayer Corps’ fight against the Twelve Kizuki. After Hane rescued her junior disciples from Doma, Makomo secured the Shogunate’s support for the Corps, while Muzan filled the vacant Upper Rank position with Nakime.
- Hane reunited Subaru Natsuki with his parents in the Underworld Bureaucracy, then married Rem three years later and entered the Demon Slayer world to experience mortal life.
- Hane taught swordsmanship to a group of orphaned children, and Makomo stayed behind to master his techniques after her junior disciples left to pursue their own path.
- Makomo left the mountain, obtained the sword Cherry Blossom Snow, and defeated a demon before battling Akaza with her extraordinary swordsmanship.
- Kanae arrived to investigate the fight, and Makomo nearly killed Akaza with a freezing sword style before he escaped at dawn.
- Makomo joined the Demon Slayer Corps, demonstrated her swordsmanship to the Hashira, and agreed to teach them her new style.
- Makomo’s former junior disciples founded the One-Heart Style Sword Sect, but Doma attacked them and gravely wounded Xunri, Mei, and Suye before Hane arrived and killed him.
- Hane gave the disciples Devil Fruits, and Makomo reunited with them before leading negotiations that secured Shogunate support for the Demon Slayer Corps.
- Muzan ordered an investigation into Doma’s death, killed Hantengu after he volunteered for the vacant rank, and named Nakime Upper Rank Three.
