Gen Sato is voicing Ranka Manku in the Disney Sparklink Stars app and Ryuu Sazame in the Iwamoto-senpai no Suisen anime, which premiered July 4, 2026.
Gen Sato has two active voice roles announced in mid-2026. On May 29, Coly revealed that Sato would join the cast of the television anime adaptation of Hiroshi Shiibashi's manga Iwamoto-senpai no Suisen as Ryuu Sazame, a supporting character. The anime premiered on July 4, 2026, on Tokyo MX and Sun TV, directed by Toshifumi Kawase at Studio Deen.
On July 6, Coly announced Sato as the voice of Ranka Manku, the youngest member of the UPbeats! unit in the smartphone app Disney Sparklink Stars. Ranka is described as an easygoing character who often pranks with previously revealed Raska Moncrief, and the two wear acorn earrings suggesting they are based on Chip and Dale. The app's core concept involves original characters based on classic Disney icons.
The two announcements establish Sato's presence in both a traditional broadcast anime and a mobile game in the same season, with no further details about his other upcoming projects provided in the stories.
