Go to the Forest Dungeon exploration, and go for the Imp Den. Fight all of them at once, and win (having one stat above at least 15 is more or less required to do so). There will be a choice to access a door rather than having your way with the imps. Go through that and you will play through the scene in which you unlock the dungeon.
