Apparently a studio called 'South of Heaven' has done a bunch of metal Ero-Game songs. Like Tori no Uta in their CD 'Keeper of Metal Key.' Yes... it's freakin' awesome, and yes... I would like to know how and whre to get these CDs! >.< Damnit! The 'Disillusion' metal from 'Answer to the Servant' kicks major a**! Plus there's 'Alice in Heaven' and 'Alice in Hell' CDs... those having stuff like Beat Angel Esclayer and Pastel Chime.
