ok, Yumiya did it again. Crazy crossovers with sexy girls, always a ok!

Hmmm, Alice, you look healthy there

I thought Marisa would be defaulted to Jotaro's spot, but Alice as Giorno is just plain odd.

Agreed. Some of the character choices here seem a little odd, but I'll be darned if Yumiya isn't able to pull it off regardless. (I'm LOLing at Yukari as Bruno, though. So perfect.) I wonder if there's any explanation for them offered on pixiv?

Bumping for explanation

Cosplay. That's an explanation in and of itself.
