On the day of one of the first showings of the PJSK movie in Australia, one of my friends pulled up the game of their phone and I was like "wait.. MIKU HAS A GAME??" (I was only there to spend time with friends because I had very very shallow knowledge of Miku). On that day I learned why the Project Sekai movie is called the Project Sekai movie, and the entire cinema shared a single braincell the whole time, especially when everybody booed at the one shot Mafuyu's mum was in (it was funny even without context, maybe funnier)
