The arrival of Kamen Rider Zero-One is more than just your usual Kamen Rider premiere. With new series starting annually fans are used to see Riders come and go, but rarely do they see one usher in a whole new era. Zero-One marks the beginning of the Reiwa era for Kamen Rider just as Kuuga did for the Heisei era back in 2000, and while this doesn't come after a long hiatus off the air it still aims to be just a significant a landmark in franchise history. Written by Yuya Takahashi ( Kamen Rider Ex-Aid , Kamen Rider Amazons: The Last Judgement ) and directed by Teruaki Sugihara ( Lupinranger vs Patranger ), Zero-One also sees legend Seiji Takaiwa pass the mantle of lead suit actor onto Yuya Nawata – whose previous portrayals include Kamen Riders Geiz, Cronus and Neo Alpha.
