In fact other than a
very occasional grunt they are entirely without voice overs, which leads to some
very odd situations as characters are shown trying to vaguely mime their way through the thankfully
very rare
cutscenes.
The narrative frame of the game is executed in a
very Japanese adventure game style — which is to say it has anime movies, fully voiced
cutscenes of characters talking on and on, and
occasional interactive decision - making (in this case, in the form of replying to mail messages from your girlfriend on your phone).
