I in the same boat as that guy looking for the demon but shes nowhere to be found, I been searching at night but no luck, I already met her once but that was a scene with the hooded girl at night in the town.
Ahh I see now, did either of you went to the guild to talk it out with the others?
'cause thats what you need to do since the cliff area is not accessible to the player(for now...?), so go to the living room
So I took the advice of continuing to level all girls up and I finally got the quest update. Ty btw!
You're welcome
