Ever since I saw the video I got just one interpretation: The video is a critic to child prostitution. That's why you see all the confused/hurt prostitutes and the children's toys. The white stuff represents the milk that children drink and the semen that... you know. I know that's really crazy, but I watched the PV a lot and discussed with my friends here and everyone agreed. ^^
I think is really cool that Ayu stands up to that kinds of absurd of our world.
