The Book of Ruin, which should have been sealed, is released along with the mysterious immortal swordsman, Bacht. Darkness overflows from the book, causing the real world and Wonder World to disappear. Touma Kamiyama, alongside members of the Sword of Logos, challenge Bacht to a decisive battle in order to stop this situation.
Unfortunately the movie Kamen Rider Saber: The Phoenix Swordsman and the Book of Ruin is not yet available on Disney Plus.
