it won't.
it'll be the same weeaboo crowd.
you'll get like a small increase in weeaboos that's it.
and like omar said, tons of people playing it at anime cons (which won't really grow the community lol).
that said. animaaaaay. i actually really like how the game looks (persona character design >>>>>> bb character design, persona music >>>>>> bb music, i actually get hype over that music). of course, it doesn't beat gear in terms of aesthetics.
as for overall game engine and balance, it's basically a mix of many many different games (go look up the mechanics and you'll see what i mean). i dunno if it's actually fun, i'd have to try it out myself.
LAST BEAT IN THE SOULLLLLLL
