A video has been released on YouTube featuring Yoko Shogenji of the idol group Hinatazaka46, who serves as a promotional ambassador for the TV anime "Snowball Earth," based on the manga by Yuhiro Tsuji, which is serialized in "Monthly Spirits" (Shogakukan), in a conversation with director Munehisa Sakai, who is in charge of the series.
Shogenji asked frank questions about "Snowball Earth," revealing the story behind the creation of original anime scenes not present in the manga, and explaining why Takuto Yoshinaga was chosen to play the main character, Tetsuo. Director Sakai offered advice to Shogenji, who said, "I've always been interested in the profession of voice acting..."
"Snowball Earth" is a sci-fi x monster x robot action series set on Snowball Earth, an Earth covered in snow and ice. The story follows Tetsuo, a shy boy, and his giant robot partner Yukio, as they return to Earth 10 years after a final battle for the survival of humanity, only to find it frozen solid. It airs every Friday at 11:30 PM on Nippon Television's anime block "FRIDAY ANIME NIGHT (FuraAni)".
