Happy and Carla destroy the mechanical heart on the Grimoire Heart airship, which turns out to be giving Hades his power. Ultear uses her magic to return the Tenrou Tree to its original state, allowing Natsu, Lucy, Gray, Erza, Wendy, and Laxus to defeat the now powerless Hades. Makarov and their guildmates recover and order Grimoire Heart to leave Tenrou Island, and then celebrate their victory. As they leave, Hades and the other defeated members of his guild discover Zeref on their ship.

Despite using Laxus’s lightning power to its fullest, Natsu’s attacks continue to have no effect on Hades. Rather, Hades awakens the true depths of his magic power before the powerless Fairy Tail wizards, immobilizing them with fear. However, Natsu bolsters his friends with the same words of courage Gildarts had given them, and leads them in one final assault against Hades. Meanwhile, Happy, Carla, and Pantherlily stumble across a strange machine and try to destroy it.

Laxus furiously battles Hades to avenge Makarov. Their fight rages until Hades gravely injures Laxus, so he transfers his own lightning magic to Natsu and tells him to defeat Hades, reasoning that Makarov must be avenged by someone with the mark of Fairy Tail. Meanwhile, the rest of the uninjured Fairy Tail members defend their wounded master and friends from Kain Hikaru, Kowazu, and Yawazu.
