Is there any kind of interview or line from Araki or whatnot where Araki confirms that Epitaph is a substand or stand of its own? It seems to be a substand since Diavolo keeps it as well as KC but I was wondering if there was any confirmarion from Araki or some line in the manga I missed or somet other canon confirmation. Thanks.
