The series is notable for its use of a fantasy setting, along with its storybook theming. Premise The human world collides with a realm of fairy tales called Wonder World due to a conflict over the Almighty Book – a legendary artifact of unparalleled power as a trio of monsters called the Megids mount a failed attempt to claim it and create more of their kind. Two millennia later however, the Dark Swordsman Hayato Fukamiya, aka Kamen Rider Calibur, betrayed his comrades upon learning a horrible truth and was reportedly 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. Becoming a novelist and bookstore owner a further fifteen years later, Touma's attempt to stop a Megid attack causes him to inherit Kamijo's title as Kamen Rider Saber and he resolves to end the conflict after being recruited by the Water Swordsman, Rintaro Shindo, of an organization of swordsmen called the Sword of Logos. Among the other swordsmen Touma meets while recovering both his memories and lost Wonder Ride Books is his childhood friend, Kento Fukamiya, who wishes to understand his father's actions after Calibur resurfaces as the Megids' ally.
