Valkyria Chronicles 4: Launch Edition - PlayStation 4

Does it come with downloadable avatars/themes just like when pre-ordering from PSN?

does it come with a controller? there is a controller in the photo, but description does not say it includes a controller.

What language options are on this game? Can you select Japanese dialogue?

I only played the 1st one. Is it following a story line or can I play this one by itself?
