I don't think you've read up much into the game. It is going to be dark, it's all about war. Balthear looks like he's going to be the next badass character you're looking for, and the newest character, Basshe seems like a dark character as well.

According to the front site, "The latest character is Basshe, a commoner of Dalmaska who rose in the military ranks to become a general. Basshe is a good leader who is very well-liked in the kingdom, but also he is surrounded by mystery and tragedy. When the King of Dalmaska is murdered, Basshe becomes the prime suspect. His character becomes even more cloudy when he negotiaties a surrender with the forces from the Kingdom of Arcadia."

Sounds like you've got some two characters that you might like there. But really, it's a little early to be making so many generalizations. We don't even know much about the game except for short little snippits.
