The film, which is a direct sequel to the 2019 anime series, is directed by Haruo Sotozaki and produced by Ufotable. The film was released on October 16, 2020 in Japan to great success, becoming the highest-grossing Japanese film and anime film of all time.

After a series of mysterious disappearances begin to plague a train, the Demon Slayer Corps' multiple attempts to remedy the problem prove fruitless. To prevent further casualties, the flame pillar, Kyoujurou Rengoku, takes it upon himself to eliminate the threat. Accompanying him are some of the Corps' most promising new bloods: Tanjirou Kamado, Zenitsu Agatsuma, and Inosuke Hashibira, who hope to witness the fiery feats of this demon-slayer model first-hand. Unbeknownst to them, the demonic forces responsible for the disappearances have already put their sinister plan into action. Under this demonic presence, the group must muster every ounce of their willpower and unsheathe their swords to save all two hundred passengers on board. Kimetsu no Yaiba: Mugen Ressha-hen delves into the deepest corners of Tanjirou's mind, putting his determination and commitment to duty to the test.


Tanjiro, Nezuko, Zenitsu, and Inosuke board a train to help Flame Hashira Kyōjurō Rengoku in his quest to hunt down a demon that has killed many demon slayers. Soon after boarding, everyone is delighted and sleeps soundly. Enmu, Lower Level One of the Twelve Kizuki, instructs four passengers, all suffering from severe insomnia, to enter the demon slayers' dreams and destroy their spirit cores so they cannot wake up again. In return, Enmu will allow them a peaceful sleep. While sleeping, Tanjiro and his companions have happy dreams. Tanjiro realizes 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. Afraid of Enmu, they attack Tanjiro, who knocks them out. As Nezuko awakens the others, Tanjiro confronts Enmu and, in the ensuing battle, decapitates him. However, Enmu does not die and reveals that he merged his head with the train. Kyōjurō 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 neck in the engine room and Tanjiro cuts it off, killing Enmu and stopping the train. However, Akaza, the Upper Moon 3, appears soon after and attacks the demon slayers. Kyōjurō fights him alone and is mortally wounded, though Akaza is forced to flee as the sun begins to rise. Tanjiro angrily calls him a coward for running away and declares Kyōjurō the winner of the fight. Kyōjurō encourages Tanjiro and his friends and dies. Hashira and the Demon Slayer Corps are informed of his death, while Tanjiro and the others mourn him.


Yūma Takahashi, producer of the animated series, indicated a desire to continue production of the series with Ufotable. The sequel project was authorized following the success of the series. A film was determined as the best format for the "Mugen Train" arc due to its shorter content and dramatic pacing. The anime series' main production staff, as well as the cast, were kept for
