Pure Stone is a title theme for the anime Akai Kodan Zillion, and was featured in both games based on the show. The song was composed by Yoshiaki Ouchi and the lyrics were written by Masami Tozawa and sung by Risa Yuuki.
This is the first game made under the Zillion license. There are two versions of Pure Stone in the Master System release. The first is based directly on the anime's title music and plays during the game's title as well as the surface of Planet X. The second uses a more somber arrangement and plays as game over music. Also, the game's Death theme uses notes from Pure Stone.
This music is rendered on the SN76489 in the Master System or Mark III.
Zillion II: Tri Formation (SMS)
The second and final game for the Zillion anime also incorporates the song Pure Stone. It is rendered on the SN76489 in both the Master System and Mark III versions.
Although no games use them, the song has lyrics.
