Hi my name is Elyssa and I will be telling you what I think the song Rolling girl sung by Hatsune Miku and created by Genjitsutouhi-P. I can relate to this song on a deep level so I love being able to tell what I think what it means. Miku are main character is being bullied and in being bullied she has developed depression *as I said I can relate to this*. I believe that "Rolling" means Cutting it self harm. The male character seen comforting Miku I see as her depression but instead of comforting her I see him as encouraging her to "Roll" or self harm, As seen in the final lines of the song "I'll stop your breath from rolling out..for now" I believe said by the male. So I believe the meaning of this song is this " A girl is being bullied at school and that leads her into a depression and self harm. In the end the depression is to much to handle and ends up killing herself"
