Not sure if 'attracted' is the right word for this, but she just loves the fact that her uncle has wings and she wishes that she had wings, too.
She's like... "Can we go for another flight, pleaseeee?~"
But Yasu is suspicious about that. He's worried that Visari might get into a trouble if he allows her to go out with Devil too often. But she asks him everytime when Dev appears in their house /shot She seems to like him alot even though he's not always that nice to her. He's a Devil after all, lol. He can be mean to everyone, unconsciously.
