Once they arrive at Fairy Tail, Lucy joins the guild. Then, Happy accompanies Natsu to rescue Macao Conbolt, as he has failed to come back from his mission on Mt. Hakobe. Lucy joins them much to Happy's confusion. At the mountain, Natsu and Lucy begin to argue but are interrupted when a Vulcan kidnaps Lucy. Natsu arrives to rescue Lucy but he is thrown down a cliff. However, Happy saves him and watches as Natsu battles and defeats the Vulcan, who turns back into Macao. Later, Macao and the team nearly fall from a cliff again but are saved by Taurus, one of Lucy's Celestial Spirits. After taking care of Macao's injuries, the team heads home, where Macao is finally reunited with his son, Romeo.
