Volume 11. After stomping the guild master, Selene takes over Diabolos and commands the seven strongest members to embark on a special quest. They must navigate their way through an enormous secret labyrinth and find Elefseria's heart. However, because Selene's gotta Selene, she makes the quest a game where she can enjoy the spectacle of seeing the members of Diabolos fight against Natsu's team in a deadly race to see who can reach the heart first. With half of the members of Diabolos supposedly at Suzaku's level of strength, it's going to be a game of survival for Natsu's team! Volume 12. The battles between Fairy Tail and Diabolos continue to rage in the labyrinth, with both sides beating the living daylights out of each other. Selene’s enjoyment of the violent spectacle comes to a screeching halt when the fire dragon god Ignia suddenly appears, throwing the worst wrench in her plans. Natsu, of course, is instantly fired up to fight Ignia, but Ignia’s got plans of his own--secret plans that may spell disaster for all! Volume 13.
