I don't get why the P4 MC would be in but not the P3 MC. It's not like the P4 guy had any more character.
it's a persona 4 fighting game,i think aegis is more there since she's a fan favorite (hasn't she got like 2 spinoff?) that said aren't they worried that now everybody will know the shocking truth of who's the villain?

you know removing rise (since she doesn't fight) there are 7 characters + aegis that makes 8,there would be two character remaining,counting one as villain guy that makes 9 which is 1 less that character select screen show
unless they decide to use the new vita port character?
