The beloved sci-fi comedy classic Sgt. Frog (Keroro Gunsou) has announced major voice casting updates for its upcoming projects. Voice actresses Makoto Koishi and Rika Nagae have officially joined the iconic alien platoon, sparking widespread enthusiasm among longtime fans of the franchise.
According to the official announcement, Makoto Koishi will take on the lead role of the ambitious yet lazy Sergeant Keroro, while Rika Nagae will bring energy to the delightfully chaotic Tamama.
