From October 10, 2021, the film was rebroadcast in episodic format as the first 7 episodes of the anime's second season, including a recut and extra bonus content.


Set after the events of the first season, Tanjiro Kamado, Zenitsu Agatsuma, Inosuke Hashibira, and Nezuko Kamado board the Infinity Train to assist the Flame Hashira Kyojuro Rengoku in eliminating Enmu, the Lower Rank One who has infiltrated the train, while defending the 200 onboard passengers.


Tanjiro, Nezuko, Zenitsu, and Inosuke board a train to assist the Flame Hashira Kyojuro Rengoku in his mission to hunt for a demon that has killed many demon slayers and civilians. Soon after boarding, all of them are enchanted and fall into a deep sleep. Enmu, Lower Rank One of the Twelve Kizuki, instructs four passengers, all suffering from severe insomnia, to enter the demon slayers' dreams and destroy their spiritual cores so that they can't wake up again. In exchange, Enmu will allow them a peaceful sleep with all of their own dreams.

During their sleep, Tanjiro and his companions have happy dreams. Tanjiro realizes that he is dreaming and tries to wake up, succeeding after a vision of his father instructs him to kill himself in the dream. At the same time, Nezuko uses her power to sever the intruders' connection, and awaken the passengers. In fear of Enmu, they attack Tanjiro, who knocks them out.

While Nezuko awakens the others, Tanjiro confronts Enmu, and in the ensuing battle, beheads him. However, Enmu does not die, and reveals that he fused his head with the train. Kyojuro instructs Inosuke and Tanjiro to look for Enmu's neck while he, Nezuko, and Zenitsu stay behind to protect the other passengers. Tanjiro and Inosuke find Enmu's neckbone in the engine room and Tanjiro severs it, killing Enmu and stopping the train.

However, Akaza, Upper Rank Three, appears soon after and attacks the demon slayers. Kyojuro fights him alone, and is fatally wounded, although Akaza is forced to flee when the sun begins rising. Tanjiro angrily calls him a coward for running away and declares Kyojuro the real winner of the fight. Kyojuro encourages Tanjiro and his friends, and dies. The Hashira and the entire Demon Slayer Corps are informed of his death, while Tanjiro and the others mourn his sacrifice.
