Bring a camera into mementos

I dont think you could use a camera OR broadcast in mementos

who said the broadcast was live?

That's a fair point, bu how do you record?
In the beginning of the game, Ryuji mentions that the camera app on his phone won't work and that there's no service...

It wasn't recorded, Futaba said she had something planned and never told anyone. Everyone was wondering what she was making for the card. Its CGI probably

Deus ex Machina?

@Kumokia if thats CGI then holy crap

Well nobody knew about it so it has to be edited
