Demon Slayer: Kimetsu no Yaiba - Mugen Train The Movie + Hashira Gou Kaigi/Chou Yashiki-hen - *English Dubbed*

Tanjiro, Nezuko, Zenitsu and Inosuke board a train[N 1] to meet the Flame Hashira Ky?jur? Rengoku and assist him in his mission to hunt for a demon that has killed more than 40 demon slayers on a train. Soon after boarding, all of them fall into a deep sleep, and Enmu, Lower Rank One of the Twelve Kizuki, instructs four passengers, all suffering from severe insomnia, to use magic ropes to enter the demon slayers' dreams, and destroy their spiritual cores so that they can never wake up again. In exchange, Enmu will allow them to have a peaceful dream.

During their sleep, Tanjiro dreams of reuniting with his late family, Zenitsu dreams of having a date with Nezuko, Inosuke dreams of going on a cave exploration mission, and Ky?jir? dreams of meeting his brother. Tanjiro realizes that he is dreaming and tries to wake up, succeeding after being instructed by a vision of his father to kill himself inside the dream. At the same time, Nezuko uses her power to burn the ropes, awakening the passengers. In fear of Enmu, the passengers attack Tanjiro.

While Nezuko awakens the others, Tanjiro confronts Enmu, and eventually beheads him. However, Enmu does not die and reveals that he fused his head with the train itself. Ky?jur? 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 him and stopping the train.

However, Akaza, the Upper Moon Three, appears soon after and attacks the demon slayers, severely injuring Tanjiro. Ky?jur? fights him alone, and is fatally wounded by Akaza, who is forced to flee when the sun begins rising. Tanjiro angrily calls him a coward for running away and declares Ky?jur? the winner of the fight, as he dies. As the Hashira and the rest of the Demon Slayer Corps are informed about Ky?jur?'s death, Tanjiro and his companions tearfully mourn him.
