In December 2020, Funimation announced that they would be streaming the official English dub of “Demon Slayer.” While they got the first opportunity to stream the hit series, other streaming platforms weren’t far behind. By early 2021, “Demon Slayer” was also available on Crunchyroll, Hulu, and Netflix. With that wider availability came a much broader audience for the anime, and the popularity of “Demon Slayer” hit an all-time high.
The sudden availability of “Demon Slayer” on multiple streaming platforms spurred another spike in manga sales. In September 2020, the “Demon Slayer” manga had over 100 million copies in circulation. The manga was already the second-highest selling series published by Shueisha, second only to the unstoppable juggernaut that is “One Piece.” By February 2021, shortly after the English dub of the anime came to major streaming platforms, the “Demon Slayer” manga had a stunning 150 million copies in circulation.
Streaming brought on a big spike, but the anime itself deserves most of the credit. When the anime first aired in Japan in 2019, the “Demon Slayer” manga had sold just 3.5 million copies. By the end of 2020, the economic impact of “Demon Slayer” was estimated at 270 billion yen in Japan. Such an incendiary rise to mainstream popularity is unheard of in almost any form of media, and “Demon Slayer” shows no sign of slowing down.
