The ending of one of the Musical numbers in the game. The idea in this song is that the choir (named the Lunabelles) sing first, and then you copy the melody, but the lyrics that pop up in the "Karaoke-field" are of course dynamically created from choices you have made in the game. Or, if  you don't want to play in "Karaoke Mode", you can enjoy the lead voice-actor's interpretation of the many variations :D
