Kamen Rider MY-TH Special Teaser: Cast & Crew Reveals A Mythical New World!

Surprise, Kamen Rider fans! Toei has just dropped a special production teaser for the newest series — Kamen Rider MY-TH. The video, released on the official Toei Tokusatsu World channel, introduces the main cast and gives us our first look at the actors behind the upcoming hero and his rivals.

The new series follows Sora Otosumi, a young man who becomes Kamen Rider MY-TH — a mouse-inspired hero. Serving as the devoted butler to Yuna Mizuki of the prestigious Mizuki family, Sora is the ultimate attendant, flawlessly handling everything from household duties to combat, even if he occasionally grumbles or talks back. He fights to protect Yuna and uphold the promise he made to her. Standing in his way are the mysterious creatures known as the Inexplicable, as well as Kamuri Minetaka, the leader of a shadowy organization that has returned after a century. Transforming into Kamen Rider MAOU, Kamuri shares Sora’s goal of eliminating the Inexplicable — yet their opposing ideals make a fierce clash between them inevitable. The new trailer has confirmed that both Sora Otosumi and Yuna Mizuki will also star in the upcoming film, Kamen Rider Zeztz: Farewell Mission, in theaters nationwide (in Japan) on July 24th, 2026.

MY-TH was teased at Kamen Rider’s 55th Anniversary event in April. Three months later, Toei confirms the mouse-themed Rider continues the chest-worn belt style from predecessor Zeztz. Cat Riders MAOU and RID wear their belts at the waist, with MAOU using a unique MAOU Driver and RID featuring the Hammer Bone Buckle. This design choice creates a striking contrast as the mouse-versus-cat rivalry unfolds. Each Driver have different abilities, including which the riders will use new egg-shaped items called Ride X-Eggs.

Kamen Rider MY-TH (仮面ライダーマイス) is the eighth Reiwa-era series, following predecessors such as Zeztz, Gavv, and Geats. Created by Shotaro Ishinomori, the Kamen Rider franchise (仮面ライダーシリーズ) launched its first television series in April 1971, sparking the Henshin Boom and spawning sequels, films, manga, and anime that shaped Japanese superhero storytelling. Fans can currently watch Kamen Rider Zeztz on TV Asahi’s Super Hero Time block Sundays at 9 AM JST, with Western audiences streaming episodes on Tokushoutsu’s YouTube channel.
