Um... yeah, they are failed Vocaloid. In terms of the song not coming out how the producer wanted it. The purpose is for Haku to represent failed attempts at producing a decent song, or failing to get the parameters correct enough to make it the Vocaloid sound decent.

Now failed Vocaloids are a gimmick and people are purposely messing up songs to have their failed Vocaloid character.
