"Kokoro Shinryaku Robot" was first uploaded on September 20, 2012. It was at first originally uploaded on 2011, however that version was removed from Nico Nico Douga and also Hinata Haruhana's YouTube account (the original version can still be heard in YouTube reprints and Hinata Haruhana's album "Mechanical Mystery"). Not too long after the original's upload, Hinata Haruhana also uploaded her own cover to the song with it's own PV.
