I don't think the story is "very good", but it's decent. Just that. "Decent". It's all a bunch of cliches put together very well, but still a bunch a cliches. It does have it's shortcomings, terrible main villain and Lao's story should've been build up a little more IMO. I don't know.
Story aside, the fact that the game forces you to play with 2 characters (Elma and Lin) the whole game to get trough the story is a feature I very much disliked and everything Tatsu-related, in general, I hated.
