Hi there! There’s finally news about something related to Kin’iro no Corda which is the release of Cool Voice that is now featuring an interview with Yuuya Uchida as well as a pin-up that was previously reported as well, which is here: https://nekonome.wordpress.com/2009/04/13/corda-update/
The magazine was released a few days ago (on April 25th). That issue also features Mamoru Miyano, Yuuichi Nakamura, Hiroyuki Yoshino, Hiroshi Kamiya, Shinichiro Miki, Kishou Taniyama, Kenichi Suzumura, Hiro Shimono, Miyu Irino, Takehito Koyasu as well as the 2 main features of the issue, Daisuke Ono and Toshiyuki Morikawa.
The seiyuu mentioned before Daisuke Ono and Toshiyuki Morikawa are only known by the picture provided by the staff blog crew. Whether they are featured or not is not confirmed yet without a bigger cover of the magazine.
Thank’s for reading!
