Barnaby’s voice actor Masakazu Morita will be a guest on Hoshizora Sunrise radio two weeks in a row, on September 18th and 25th. The radio airs on FM NACK5 at 23:00 JST on Sundays. Instructions on how to listen to it through Keyhole TV here.

The tweets don’t give much additional information, but it’ll be a Tiger & Bunny feature and they’re accepting questions to Morita through the Hoshizora site (in Japanese, of course).
