Shunta Sono, a member of the pop group M!LK, will appear as the enemy Kamen Rider Yumemi in the film Kamen Rider Zetts (working title), part of the double feature Kamen Rider Zetts & Super Space Sheriff Gavan Infinity W Hero Summer Movie 2026. Sono plays Shuma Kumon, a young elite who chairs the National Public Safety Commission on the surface but secretly transforms into the dark rider Yumemi, who turns the real world into a daydream and controls people's minds. The role required swordsmanship training and full-scale action choreography, both firsts for Sono. He said he discussed the transformation pose with the director and paid close attention to it, drawing on his childhood admiration for the series after watching Kamen Rider Hibiki and Kamen Rider Kabuto. Fellow M!LK member Jutaro Yamanaka, who appeared in Kamen Rider Gotchard, gave him acting advice. The film opens July 24.
