I was like.... Whut ?! Gotta be kidding, right ?

First, your hand shortened or something ?
Second, the first and last time I saw you wearing fake nails was when you were advertise those of your merch.
Third.............. This is... Kawaii en tabarnak x_X

But in the end, it's KITTY's nails, so it's okay. (KITTY's being one of Kaya's female dancer... The other one is Ayano... If my memory is good (it ain't), in Salon de Chocolat, Kitty was the one with the blonde, lion-like hair-do...)
