Arc 20The Infinity Castle Battle
Teiichi prepared the Hashira and Corps members for Muzan’s final battle while they shared their pasts and trained together. Muzan drew the Corps into the Infinity Castle, where the Hashira faced the Upper Ranks as Teiichi rushed to Kagaya Ubuyashiki.
- Teiichi rallied the Hashira to prepare for Muzan, and Giyu explained why he felt unworthy of his position before agreeing to fulfill his duties.
- The Hashira shared the losses and hardships that led them to the Demon Slayer Corps, and Teiichi urged Sanemi to reconsider rejecting Genya.
- Teiichi explained the Upper Ranks’ abilities, delayed Nezuko’s transformation to keep Muzan from sensing her, and began training the Hashira in strength, speed, breathing, and teamwork.
- Kagaya told Teiichi that he planned to use himself as bait for Muzan, but Teiichi later learned that Nakime had transported the Corps into the Infinity Castle and hurried toward Kagaya.
- The Hashira and Corps members fell into the Infinity Castle, where Muichiro encountered Kokushibo and Akaza defeated Tanjiro, Zenitsu, and Inosuke before Kyojuro arrived.
- Gyomei fought Muzan, while Kyojuro, Obanai, Tanjiro, Zenitsu, and Inosuke battled Akaza, whose attacks gained the advantage.
- Kyojuro failed to cut through Akaza’s neck and lunged to intercept an attack aimed at Tanjiro, while Sanemi joined Muichiro against Kokushibo, who charged at Genya.
