So I finished the story mode today and while I definitely would have preferred the english dub, the Japanese is passable. The voices sound a little weird at first but it's not like Guilty Gear where you have to mute May to even tolerate the game. I'll agree the story really drags for the first, like, 80%, and honestly is pretty bad compared to CPEX, but I think that it has a pretty satisfying ending. The plot twists where also pretty good; a couple of the revelations actually caught me off guard but still made sense. If you like the gameplay of BB at all I would definitely recommend picking up a copy. If you just want the story you can probably just find a full upload on Youtube or something.
