Galuna Island arc
She appears with the rest of the villagers, at the arrival of Natsu, Gray, Lucy, and Happy, in robes. When Moka, the mayor, tells them to take their robes off, Lulu is revealed with a leg similar to a Demon's. Moka then explains the situation to the Mages. Then, the moon turns purple and the villagers transform into complete Demons.
When Gray wakes up after his defeat by Lyon in the village storage location, a little bit farther away from the village, Lulu is there to greet him and informs him all the villagers had to move here after the village was attacked last night. She also tells him that thanks to his friends nobody was injured, and that they are waiting for him in a tent.
Later on, it is revealed the villages were being confused by the side-affects of Team Lyon using Moon Drip, and that the villagers were actually Demons in the first place, but mistook their ability to turn into humans as their true forms.
