Chapter Summaries

Chinatsu persuaded Oyakata-sama to let her serve as bait for Muzan instead of sacrificing himself, then told the Demon Slayer Corps that killing Muzan was their only chance to save him. They scheduled the Infinity Castle battle for a week later and prepared to strengthen Oyakata-sama until then.

• Chinatsu asked Amane to give Oyakata-sama as many restorative supplements as possible, regardless of side effects.

Obanai Iguro and Muichiro Tokito mastered the Transparent World before the Demon Slayer Corps Headquarters’ location was leaked. Muzan confirmed the discovery through Nakime and eagerly planned to attack the next night, but killed the demon who found it after using the report.

• Chinatsu rose, drew her Nichirin Blade, and faced Muzan as the final battle began.

• Doma revealed that he had become Upper Rank One after Kokushibo’s death and had received more of Muzan’s blood.
• Doma summoned an enormous ice bodhisattva with his Blood Demon Art, and its palm struck toward Chinatsu and Inosuke.

Chinatsu fought Doma while protecting Inosuke from his ice attacks and sent him to find the demon controlling the Infinity Castle. Left alone with Doma, Chinatsu prepared to avenge the people he had killed as their duel began.

• Doma's Mystic Ice Bodhisattva struck at Chinatsu and Inosuke, and Chinatsu kicked Inosuke clear before dodging the attack herself.

• Chinatsu turned her Nichirin Blade bright red and took her stance against Doma, ready to settle their scores.

Chinatsu arrived at the battlefield to find Muzan fighting the wounded Demon Slayer Corps, and sent Tanjiro to care for the injured so she could face Muzan alone.

• Chinatsu reminded Muzan that Yoriichi had defeated him instantly and that he had fled in terror, provoking Muzan's fury.
