Since Part 6 finished thought I might as well make an updated version including its OPs. Anyway, since Suzi Q is Italian, and she is the grandmother and great grandmother of Jotaro and Jolyne respectively, they are both also Italian. Giorno is the son of Dio (Jonathan), British person and a Japanese woman, meaning he is not Italian. Weather is Pucci's brother, and Pucci is Italian, so Weather is Italian as well. I counted someone's stand as an extension of themself, so for the purposes of this video Star Platinum and Stone Free are Italians.
