Find the Kujara Washing Shed.
Talk to the man outside the entrance to the Sculptor's Hut to activate the event. Now you all have to do is find the Washing Shed.
Go back to the lowest floor of the area and follow the road all the way to right, where you can find a red door next to a save point. Walk through the door and the event is cleared.
