The anime adaptation of Koyoharu Gotouge’s Demon Slayer: Kimetsu no Yaiba manga has been one of those big worldwide crossover titles, notably with the feature film doing so well.
With the dub having progressed there, Hulu previously scheduled it to make the leap to the service so it can join the subtitled side that they’ve had.
The manga from Koyoharu Gotouge began in early 2016 and wrapped up in 2020 with twenty-three volumes.
