You sure that's Miku and not Sailor Moon? It could be many skirt-wearing twin-tail-sporting girls...I don't see anything that pegs it as Miku specifically.

You mean that box next to the lamprey eel box which says "border something Yukari"?
Arceon said: Similarly Youmu is on a box too, on the high shelf to the left of the "center" shelf. The box is in the dark so it is rather hard to spot.
If that is Youmu, why does she have frills on her shoulders like Sakuya and not so short hair?
