Kamen Rider Saber will start with a total of five Riders, however, the series may have over ten Riders. Saber is the second Kamen Rider show of the Reiwa Era following Kamen Rider Zero-One which ended on Sunday, October 30th.
Kamen Rider Saber features a world based on fairy tales & fantasy adventures colliding with our own, centered over conflict with The Book– a legendary artifact that contains unparalleled powers and secrets. In ancient times, a sinister group known as Megiddo came forth to take The Book for themselves- as a result of the conflict, chapters of The Book were scattered across the world (becoming the WonderRide Books seen in toy listings). A collection of heroes known as the Sword Of Logos unites to fight the evildoers and reclaim The Book. The battles between both groups will throw the world into chaos- with people and places vanishing between worlds.
Directed by Takayuki Shibasaki and written by Takuro Fukuda (Kamen Rider Ghost), Kamen Rider Saber will debut September 6th.
