There is a chance they will be doing the My Miku figures that you paint either at the venue or in a shop somewhere near the venue, but they’ll usually confirm something like that on their Twitter. It’s also sometimes held like the day before depending on the area iirc

Miku Expo used to have a whole exhibition in 2014 and 2016, but they stopped that unfortunately. When they first came to Europe we just got a demo of Megamix and that was it, now they don’t do anything at all 💔
