IIRC (and using the walkthrough as a guide, check the dink solutions) you can't get into southtown castle until you've talked to the people in the northernmost village. This is across the bridge, so if you haven't made it across there then I'm not sure what's wrong, assuming that you've killed the monster, talked to Rain for your reward and rested.
