She doesn't celebrate Christmas, Halloween, or Valentine's day... or even Summer in general I guess. Maybe she'll celebrate Easter. Easter Bunny Diana... (Ew.) lol But aside from jokes, hope she can be considered for this years Snow Down at least. Could honestly see her fitting the Death Sworn skin line very well for Halloween too. Idk.. she just has to many serious skins. None that are just for fun.
I'd say chinese new year is a festive time where the lunar revel of Lunar goddess diana came .
I wouldn't mind seeing something a bit more festive for my main Moon Lady, even if it wouldn't fit her usually serious demeanor too well.
Though, personally, I'd still love to see a "Solari Diana" skin from her pre-Lunari days. That'd be my ideal skin just because I think it'd be fun. Give her Leo's sword, give Leo a Lunari skin for funsies with the Crescent Blade just for a switcheroo there. Yes please.
I would like to see a Santa
