I missed out on the Premium Bandai effect, but I still want the Moonlight Butterfly somehow...
So I made one myself using concert stickers and plastic sheet.
It was a very easy and inexpensive build.
As for the main ∀ figure...I replaced the saber blade and repaired some broken parts, but it's basically a knock-off assembly.
