Flame Hashira Kyojuro Rengoku receives new orders: Travel to the Mugen Train, where over forty people have gone missing, and conduct an investigation.
Leaving the Demon Slayer Corps Headquarters, he sets off on this new mission.
I'll just devour the humans that seem tasty,

con sangre sabrosa.
Me como a los humanos
con sangre sabrosa.
Humanos saborosos eu como, mas os com gosto
