In an epic confrontation, Tanjiro and his fellow Demon Slayers have fought on through the night, suffering terrible losses against the King of Demons, Muzan Kibutsuji. Dawn is breaking soon, and if they can keep Muzan at bay just a little longer, it will be the end of the centuries-long struggle. But Muzan will stop at nothing to destroy the Demon Slayers and unleash his most terrible powers. And if he can't defeat them, he may even be able to cause the Demon Slayer Corps to destroy itself from within. All fates and destines will be decided as the sun begins to rise… For teen audiences.
