Okay, I'm stuck. I'm at the part where I have to find 3 people and beat them so the old guy from the mountain will teach me Soulboost. I found and beat the girl at the police station. I found one guy at the diorama store but can't beat him because I don't know how to do combos. And then I found the other guy by the sea and then he ran off. So my questions are: 1) How do I do combos? I need at least a 160 combo. 2) Where did the guy by the sea run off too? He said something about a tall building.
