The chant is featured prominently in the Xbox/Director's cut version of Fatal Frame II, in which it can be heard playing while the main menu screen of the game is open after loading the game. The lyrics to the song were published in the Fatal Frame Fanbook.
Lyrics
This chant takes the place of the voices of this world
those devoted to the Crimson Sacrifice and Kusabi
who originally committed the crimes and sins
pray for the sacred wind of the Land of the Dead
the revered Crimson Butterfly that shall set us free
the revered Crimson Butterfly that shall set us free
