Novelist Touma Kamiyama's childhood memories are fragmented. He dreams of a swordsman fighting a great battle, and a girl who disappeared... Suddenly, part of the city disappears, swallowed up by a great book, and Touma discovers that his destiny overlaps with the Sacred Swordsmen who protect the Wonder Ride Books! Taking up the Sacred Sword of the man who protected him so long ago, Touma becomes the Flame Swordsman, Kamen Rider Saber! (Ununnilium)

The Book of Ruin is released along with the mysterious immortal swordsman, Bacht. Darkness overflows from the book, causing the real world and Wonder World to disappear. The Sword of Logos must challenge Bacht to stop this situation.

Touma, Yuri, and Mei somehow ended up in the World of Zenkaiger while the Zenkaigers, except Juran, ended up in the World of Saber. The reason for their swap is due to a man who wishes to rid the world of heroes. How does a male, teenage artist tie into this? And why are they sent into different stories with previous Kamen Riders and Super Sentai Teams?

Kamen Rider Revice, Saber, and their allies fight against a Kamen Rider from the future while attempting to help a time-displaced scientist reconcile with his now-elderly son.

Eight years after the battle for the Book of Omniscience, the peaceful lives of Touma, Rintaro, Mei, and Kento are troubled by a mysterious new Falchion who can seemingly erase people from existence altogether.
