Rolling Girl

Released on February 14, 2010, this song hit the 2nd position in the Weekly VOCALOID Ranking of the week of its debut and achieved the million mark on June 28, 2010.
The lyrics are very vague, but the general idea is that a girl with far-off dreams and a history of constantly "failing" takes to "rolling", even though her goal is still too far away and she would rather "stop her breathing". Commonly, the song has been interpreted as being about bullying, being shunned, or failing constantly, leading her to commit suicide.
