Kanzaki Kendo, the national kendo champion, got involved in a fantasy dispute after encountering a fierce battle between a Kamen Rider and a monster. He is a born swordsman, from questioning the power of fantasy to resonating with the lost holy sword, obtaining a blank book and the Shadow Style Sword, and transforming into a Kamen Rider Shadow Style. He combines pure sword skills with fantasy power to uncover family secrets, and ultimately protects the balance of the two worlds with his partners.
