Demon Slayer: Kimetsu no Yaiba Episode 27: Flame Hashira Kyojuro Rengoku

Rengoku Kyojuro, the Flame Hashira, receives orders to investigate the **Mugen Train**, where more than forty people have disappeared, and he immediately leaves the Demon Slayer Corps Headquarters for the assignment.

At the train station, he begins looking into the case and checks the area where a conductor’s body was found, treating the disappearances as part of the same troubling incident. While investigating, he encounters a grandmother and granddaughter who are selling bento boxes, and he speaks with them as part of his search. The episode establishes that Rengoku is now actively working the Mugen Train case on his own, following the latest orders from the Corps.

The focus stays on Rengoku’s arrival and initial investigation rather than a full battle, with the episode setting up the larger Mugen Train mystery and showing him as the Hashira assigned to lead that inquiry.
