# Kamen Rider Saber

Kamen Rider Saber (仮面ライダーセイバー（聖刃）, Kamen Raidā Seibā) is a Japanese tokusatsu drama, the 31st entry of Toei Company's Kamen Rider franchise, and the second series to debut during the Reiwa period. The series premiered on September 6, 2020, joining Mashin Sentai Kiramager, and later, Kikai Sentai Zenkaiger in the Super Hero Time line-up after the finale of Kamen Rider Zero-One before being succeeded by Kamen Rider Revice on September 5, 2021. The series is notable for its use of a fantasy setting and its storybook theming.

## Premise

The human world collides with Wonder World, a realm of fairy tales, because of a conflict over the Almighty Book – a legendary artifact of great power that a trio of monsters known as the Megids seek to acquire in order to create more of their kind, and that an organization of swordsmen known as the Sword of Logos seeks to protect. Two millennia later, the Dark Swordsman Hayato Fukamiya, also known as Kamen Rider Calibur, betrayed his comrades after learning a terrible truth and was seemingly killed by the Flame Swordsman Daichi Kamijo, with a girl named Luna being an apparent causality of their fight. Daichi gave his Wonder Ride Book to a boy named Touma Kamiyama before leaving his sword behind.
Fifteen years later, Touma has become a novelist and bookstore owner. After being caught in a Megid attack, his attempt to stop it causes him to inherit Kamijo's title as Kamen Rider Saber and he resolves to end the conflict after the Water Swordsman, Rintaro Shindo, recruits him to join the Sword of Logos. Among the other swordsmen Touma meets while recovering his memories and the lost Wonder Ride Books is his childhood friend, Kento Fukamiya, who wishes to understand his father's actions after Calibur reappears as an ally of the Megids.

## Production
