I don't, mind explaining? Also who would be Polnareff, Iggy and Dio in this scenario?
Natalia has dark skin = Avdol Kaede is the oldest on the group = Joseph Miho is the youngest one = Jotaro Chiaki likes older people than herself is = Kakyoin
As for the others? Dio maybe Rin, Polnareff as Uzuki and Mio as the dog.
