Kazuki Ura has been cast as Shirō in the Pokémon Horizons anime and as an unnamed cast member in the upcoming The Vermilion Mask anime, which is set to debut in October 2026.
Kazuki Ura was added to the cast of the Pokémon Horizons anime in late June 2026. He voices Shirō, a muscular character with tremendous power, who appears in the new "Wonder Voyage" arc that premiered on May 22. The arc incorporates elements from Pokémon spinoff games and introduces new characters tied to Lumiose City. Yū Serizawa was also added to the cast as Navi.
A week later, Ura was named among the cast for the anime adaptation of Dr.Poro and Nabana Naba's The Vermilion Mask. The first main trailer and full cast were revealed during Crunchyroll's Anime Expo panel. The anime is directed by Tetsuaki Watanabe at 100Studio, will debut in October 2026, and will run for two cours. Crunchyroll will stream the series.
The two announcements, made within days of each other, establish Ura as a voice actor active in both a long-running franchise and a new supernatural action adaptation. No further details about his role in The Vermilion Mask have been disclosed beyond his inclusion in the cast.
