I posted a subtitled video of an interview with Gackt about a voice acting role on popular anime, 'Sket Dance'. On one of the episodes for this show there is a music festival, for which Gackt's character sings a song. The song is title 'Ikitoshi Ikiru Subete ni Tsugu' (生きとし生けるすべてに告ぐ), which means something like 'I call out to all that can live as lives'.......I think. It's a little complicated.
Anyway, a CD containing this song and other songs that featured in that episode will be released in Japan on the 28th of September. It will be called (SKET DANCE: KAIMEI ROCK FESTIVAL EDITION).
