Once I said that I have a back fetish. But, it's not just anyone's back. Obviously I have to like (or interact with) the person before I like his back XD
And so finally I've found pictures that shown Umi's back!
My gratitude for Tohya who has taken and put the pictures at his blog. You're a good stalker, Tohya! X3
That back, somehow I feel it warm and giving sense of "older brother" *jumps out to his back* X3
