Why won't there be a Demon Slayer season 5?
The Demon Slayer Infinity Castle movie will soon arrive in UK cinemas.
The first Demon Slayer: Infinity Castle movie is officially in cinemas, with the franchise almost at its end.
Continuing the Demon Slayer story after adapting the Hashira Training arc, a storyline that's generally agreed to represent the calm before the storm, Infinity Castle ramps up the action as the heroes prepare to battle their demonic enemy, Muzan Kibutsuji.
The wildly popular anime, based on the manga by Koyoharu Gotouge, follows young Tanjiro in his mission to exact revenge after his family is massacred by demons and his younger sister is turned into a demon.
Here's everything we know about why there won't be a Demon Slayer season 5.
Why won't there be a Demon Slayer season 5?
There won't be a Demon Slayer season 5 simply because the anime is being wrapped up with three feature films instead of another season.
The first film arrived in UK cinemas on 12th September 2025, two months after its July release date in Japan, where Demon Slayer fans turned out in droves, causing the movie to spend six consecutive weeks in the number one spot at the Japanese box office.
The wait for the second film in the trilogy now begins!

"The Demon Slayer Corps members and Hashira engaged in a group strength training programme, the Hashira Training, in preparation for the forthcoming battle against the demons, Muzan Kibutsuji appears at the Ubuyashiki Mansion.
"With the head of the Demon Corps in danger, Tanjiro and the Hashira rush to the headquarters but are plunged into a deep descent to a mysterious space by the hands of Muzan Kibutsuji.
