Team Natsu, Wendy, Carla, Elfman and Warren are hired by the Balsamico family to capture the escaped convict Velveno who had infiltrated the Magic Dance Ball with the use of his Transformation Magic. During the ball, Erza, Lucy, Natsu, Gray, Wendy and Elfman are on the lookout for Velveno while Warren, Happy and Carla watch from afar with surveillance Lacrima. However, the group fails to find Velveno and the clock quickly chimes midnight, prompting Balsamico to announce that whomever manages to get to the Balsamico ring first will earn the right to propose to his daughter, Aceto. The boy dancing with Wendy then reveals himself to be Velveno and uses the Sky Dragon's Roar he copied from her to take the ring.
Seeing the escaped convict, Natsu charges at him and attacks with Fire Dragon's Iron Fist. Velveno attacks him with the same attack as well. Natsu then attacks with Fire Dragon's Roar and Velveno mimics his move once more, causing an explosion. Velveno then reveals that he had copied the Magic of every Fairy Tail Mage that attended the ball. Hearing this, Erza steps forward and tells Gray and Elfman to protect Aceto. She then requips into her Purgatory Armor and charges at Velveno. Velveno requips into the same armor as well and parries Erza's attack. Velveno then tells the group that he didn't come there to fight, but to propose to Aceto, putting an abrupt stop to the fight.
Velveno then tells the group his story, about how he was not allowed by the Count to visit his daughter because of the difference in the social standings and how he got involved in crime. He then kneels to Aceto and asks her to be his wife. Despite her father's objections, Aceto agrees with the condition that Velveno turns himself in for the crimes he committed. Velveno agrees and the two promise to wait for each other.
