A final premiere date for season 2 of the Demon Slayer: Kimetsu No Yaiba anime hasn't been announced yet, but more details about the season have been revealed.
While a specific date wasn't revealed, the official Demon Slayer website confirmed that the second season will air continuously across 2021's Fall anime season and into the 2022 Winter season. The series will air on Fuji TV in Japan, in the 11:15 P.M. timeslot on Sunday nights. As reported by Oricon, Yuriko Nakamura, a manager at Fuji TV, confirmed that the broadcaster will air the season without any edits to the anime's content. The second season will adapt the fan-favorite Entertainment District Arc from the manga, which primarily takes place within a city's red-light district and features some suggestive content, but Nakamura confirmed that the series has passed the usual standards-and-practices review and will be broadcast without any changes or censorship to the original story. Funimation has confirmed that it will simulcast the series internationally when it debuts.
More details about Season 2 are scheduled to be revealed on Sept. 25, when Fuji TV will air the first unedited broadcast of the Demon Slayer movie, Mugen Train. The TV premiere of Mugen Train will be preceded by the airing of five TV specials, which will recap and condense the events of the first season of the anime series and will feature new art and behind-the-scenes material. An international release for these specials has not been confirmed at this time.
Demon Slayer: Kimetsu No Yaiba was originally created by Koyoharu Gotouge and began its serialization in Weekly Shonen Jump in 2016. Gotouge's creation is the latest series to enter the list of the top 10 best-selling manga series of all time, with over 150 million copies in circulation worldwide. The manga ended in 2020 with the publication of its 205th chapter. The anime adaptation premiered in 2019, and was followed up by the release of the Mugen Train movie in 2020. Unlike many theatrical releases based on shonen series, Mugen Train is not an anime-original story, but a direct adaptation of the canon story arc of the same name from the manga. The movie is the highest grossing anime film of all time, breaking the record that was set by Studio Ghibli's Spirited Away in 2001.
In addition to the premiere of the new season, Demon Slayer fans also have the release of The Hinokami Chronicles to look forward to this fall. The Hinokami Chronicles is the first console game in the franchise and is being developed by CyberConnect2, who previously worked on the Naruto: Ultimate Ninja Storm series of games. The game will be published by Sega on October 15 for Windows PCs, Playstation 4, Playstation 5, Xbox One, and Xbox Series X|S.
