Seikima-II - Midnight Soldier (Unreleased song)

An unreleased song entitled Midnight Soldier. I have found no info about it other than that it was probably written by Damian Hamada. I also don't know which members are performing the song here, other than Demon on vocals, and most likely Zod on bass. If anyone has any info on the demotape this song is from, please tell me. If you have a copy of, or a rip of the demotape which sounds better, I'll trade something rare for it.
