The little we see of the characters in the demo shouldn't be enough to write them off completely and decide they're unlikeable, Taiga only really had one conversation and Yoichi has shown enough complexity in the few he had that there's clearly some depth behind the aggression that needs to be discovered.
I hope you can get over your first impressions when the full game comes out. I'm sure there will be a reason that everyone behaves the way they do, both those who are overly aggressive and those who seem to be overly meek.
