[mimika]

hi guys~ i've been wonderin about this for a while..I have the RAINBOW and i've been lookin thru the booklet that i came across the last page which shows part of ayu's body but in a weird position...i've been wondering what position is she having..i mean it looks like part of her leg but it just doesn't fit with the rest of the picture....anyone knows?? There following pic on the rite is what i am referring to... thx if anyone knows!!
