[@Lugubrious] Good post from you. Sorry I haven't posted in ages. Worth noting: Erina should be able to at least see the Stands, since it's been established that she can see supernatural entities, and in particular the Stand Heavy Fuel provides the appropriate precedence.

I must have forgotten that, because it is a little shaky in my opinion.  The rule insofar as I can remember it is 'only Stand users can see Stands', not necessarily that whoever has spiritual abilities can see them.  But then again, the JJBA rules are broken with surprising regularity by its own canon, and since I didn't catch it the first time (or permitted it the first time) it's not an issue.  I'll go ahead and edit.
