Arc 12The Final Battle Approaches
After Nezuko conquers sunlight, Rokuya recognizes that Muzan will target her and begins preparing the Demon Slayer Corps for the final battle. He helps arrange Muzan’s ambush, protects Nezuko with humanizing medicine, and ends the arc surrounded by allies as the battle draws near.
- Nezuko’s blood turned Tanjiro’s blade bright red, and Tanjiro killed Hantengu’s true body as sunrise arrived, and Nezuko survived in the sunlight, revealing her immunity to Muzan.
- Rokuya realized Muzan had learned of Nezuko’s immunity, then helped evacuate the Swordsmith Village as Muzan sent Upper Ranks to capture Nezuko and kill him.
- Rokuya and the others fought Doma until Kyojuro Rengoku, Giyu Tomioka, Sabito, Obanai Iguro, Sanemi Shinazugawa, and other Demon Slayers arrived and forced Doma to retreat.
- Rokuya reported to Kagaya that Muzan would pursue Nezuko and proposed using the Ubuyashiki estate as bait, while the Corps began final Hashira Training.
- Rokuya learned Kaigaku had become a demon, arranged to keep the news from Jigoro Kuwajima, and agreed to train Zenitsu to fight Kaigaku.
- Rokuya worked with Tamayo on a plan to weaken Muzan, then injected Nezuko with medicine that suppressed her demon traits and left her in Sakonji Urokodaki’s care.
- As Muzan’s forces found the Headquarters, Rokuya briefed the Hashira on Kagaya’s planned trap and promised to protect the Ubuyashiki family from the explosion.
- Rokuya assigned Tanjiro to the main assault team and asked Kanae and Shinobu to stay by his side, and both agreed as the final battle neared.
