That is due, in part at least, to Akeno being the daughter to one of his most trusted friends among the Fallen Angels. As such, I would say he might fancy himself an uncle of sorts. As for her sex appeal, her potential isn't shocking. What 'is' shocking is that her sex appeal and potential is higher than most Fallen Angels and she is a half-breed. There in lies the shock of Azazel's analysis about Akeno. Well, this is my opinion anyways, albeit one backed up with information from the wiki and the novels.
