Natsu Dragneel, Lucy Heartfilia, and Happy travel to the city of Marguerite to visit Lamia Scale, which now includes Wendy Marvell and Carla. Wendy declines the trio's invitation to help reorganize Fairy Tail, thinking that leaving Lamia Scale would upset her friend and current partner Shelia Blendi, but is admonished by Shelia for staying out of pity. That evening, the city is invaded by a horde of 100,000 monsters commanded by Orochi Fin, a rival guild to Lamia Scale. Taking Happy over Natsu's objections, Shelia flies off to help Wendy defeat the wizard controlling the monsters; in his anger, Natsu stampedes through the advancing horde in pursuit of Shelia and Happy.
