Toei unveiled Kamen Rider My-th, a mouse-themed Reiwa-era Rider whose teaser shows a chest-mounted transformation belt and an egg-shaped collectible. The reveal names two additional Riders, Kamen Rider Rid as a second Rider and a villainous Kamen Rider Maou. The teaser brief includes the tagline "Awakening from a Century's Slumber. People's wishes endure, and a falling star becomes a MYTH." Global streaming of the reveal was confirmed. Writer Naruhisa Arakawa, known for work on earlier Kamen Rider projects, is reported as the MY-TH writer. Social discussion highlighted the chest-worn Driver as a deliberate design choice to contrast cat and mouse motifs and noted the series title is commonly pronounced like "mice."
