im so into fatal frame that i started listening to its older theme song from tsukiko amano, 天野月子...especially the theme songs from fatal frame 2 and 3, theyr're the best
the title of the songs from fatal frame 2 is called chou, 蝶 (means butterfly) while the third one was called koe, 聲 (means sound if not mistaken)
this is chou mv
and this is koe mv, my personal favourite
and the latest theme song in fatal frame 4 was not bad either, called ゼロの調律 (just call my name), so sit back and relax!
