Yusei Yagi is a member of the dance-and-vocal group FANTASTICS and has been announced as a guest voice actor in the new Keroro Gunsō film, while also contributing the opening theme for Magilumiere Co. Ltd. Season 2 as part of the duo syudou × Yusei Yagi.
Yusei Yagi, a member of the dance-and-vocal group FANTASTICS, has two announced anime-related credits from mid-2026. In a May 30 story, he was named among seven guest voice actors for the upcoming film "New Theatrical Version ☆ Keroro Gunsō: Revival and Immediate Crisis of Earth's Destruction!" The film marks the first new Keroro movie in 16 years and commemorates the anime's 20th anniversary. Yagi joins a cast that includes fellow idol group members, a comedian, and veteran seiyuu such as Tomokazu Seki and Koichi Yamadera. The film is directed by Yuichi Fukuda and opens nationwide on June 26.
Less than three weeks later, a June 18 story revealed that Yagi is also part of the musical duo syudou × Yusei Yagi, which performs the opening theme "Late Magic" for Magilumiere Co. Ltd. Season 2. A 30-second promo video featuring the theme was released alongside the announcement of two new cast members, Manami Iwami and Masaya Fukunishi. The second season of the workplace magical-girl series is set to premiere in Summer 2026. The first season will stream free on Jump+ YouTube starting June 20.
These two stories establish Yagi's involvement in anime as both a voice actor and a musician within a short span of time, though no further details about his voice role in the Keroro film or his broader career trajectory are provided in the coverage.
